Conference Coverage

It remained an open question in 2018, on the unveiling of the COAPT trial’s 2-year primary results, whether the striking reductions in mortality and heart-failure (HF) hospitalization observed for transcatheter edge-to-edge repair (TEER) with the MitraClip (Abbott) would be durable with longer follow-up.

The trial had enrolled an especially sick population of symptomatic patients with mitral regurgitation (MR) secondary to HF.

As it turns out, the therapy’s benefits at 2 years were indeed durable, at least out to 5 years, investigators reported March 5 at the joint scientific sessions of the American College of Cardiology and the World Heart Federation. The results were simultaneously published in the New England Journal of Medicine.

Patients who received the MitraClip on top of intensive medical therapy, compared with a group assigned to medical management alone, benefited significantly at 5 years with risk reductions of 51% for HF hospitalization, 28% for death from any cause, and 47% for the composite of the two events.

Still, mortality at 5 years among the 614 randomized patients was steep at 57.3% in the MitraClip group and 67.2% for those assigned to meds only, underscoring the need for early identification of patients appropriate for the device therapy, Gregg W. Stone, MD, said during his presentation.

Dr. Stone, of the Icahn School of Medicine at Mount Sinai, New York, is a COAPT co-principal investigator and lead author of the 5-year outcomes publication.

Exclusions based on LV dimension

The COAPT trial included 614 patients with HF and symptomatic MR despite guideline-directed medical therapy. They were required to have moderate to severe (3+) or severe (4+) MR confirmed by an echocardiographic core laboratory and a left ventricular ejection fraction (LVEF) of 20%-50%.

Among the exclusion criteria were an LV end-systolic diameter greater than 70 mm, severe pulmonary hypertension, and moderate to severe symptomatic right ventricular failure.

The systolic LV dimension exclusion helped address the persistent question of whether “severe mitral regurgitation is a marker of a bad left ventricle or ... contributes to the pathophysiology” of MR and its poor outcomes, Dr. Stone said.

The 51% reduction in risk for time-to-first HF hospitalization among patients assigned to TEER “accrued very early,” Dr. Stone pointed out. “You can see the curves start to separate almost immediately after you reduce left atrial pressure and volume overload with the MitraClip.”

The curves stopped diverging after about 3 years because of crossover from the control group, he said. Still, “we had shown a substantial absolute 17% reduction in mortality at 2 years” with MitraClip. “That has continued out to 5 years, with a statistically significant 28% relative reduction,” he continued, and the absolute risk reduction reaching 10%.

Patients in the control group who crossed over “basically assumed the death and heart failure hospitalization rate of the MitraClip group,” Dr. Stone said. That wasn’t surprising “because most of the patients enrolled in the trial originally had chronic heart failure.” It’s “confirmation of the principal results of the trial.”
 

Comparison With MITRA-FR

“We know that MITRA-FR was a negative trial,” observed Wayne B. Batchelor, MD, an invited discussant following Dr. Stone’s presentation, referring to an earlier similar trial that showed no advantage for MitraClip. Compared with MITRA-FR, COAPT “has created an entirely different story.”

The marked reductions in mortality and risk for adverse events and low number-needed-to-treat with MitraClip are “really remarkable,” said Dr. Batchelor, who is with the Inova Heart and Vascular Institute, Falls Church, Va.

But the high absolute mortality for patients in the COAPT control group “speaks volumes to me and tells us that we’ve got to identify our patients well early,” he agreed, and to “implement transcatheter edge-to-edge therapy in properly selected patients on guideline-directed medical therapy in order to avoid that.”

The trial findings “suggest that we’re reducing HF hospitalization,” he said, “so this is an extremely potent therapy, potentially.

“The dramatic difference between the treated arm and the medical therapy arm in this trial makes me feel that this therapy is here to stay,” Dr. Batchelor concluded. “We just have to figure out how to deploy it properly in the right patients.”

The COAPT trial presents “a practice-changing paradigm,” said Suzanne J. Baron, MD, of Lahey Hospital & Medical Center, Burlington, Mass., another invited discussant.

The crossover data “really jumped out,” she added. “Waiting to treat patients with TEER may be harmful, so if we’re going to consider treating earlier, how do we identify the right patient?” Dr. Baron asked, especially given the negative MITRA-FR results.

MITRA-FR didn’t follow patients beyond 2 years, Dr. Stone noted. Still, “we do think that the main difference was that COAPT enrolled a patient population with more severe MR and slightly less LV dysfunction, at least in terms of the LV not being as dilated, so they didn’t have end-stage LV disease. Whereas in MITRA-FR, more of the patients had only moderate mitral regurgitation.” And big dilated left ventricles “are less likely to benefit.”

There were also differences between the studies in technique and background medical therapies, he added.

The Food and Drug Administration has approved – and payers are paying – for the treatment of patients who meet the COAPT criteria, “in whom we can be very confident they have a benefit,” Dr. Stone said.

“The real question is: Where are the edges where we should consider this? LVEF slightly less than 20% or slightly greater than 50%? Or primary atrial functional mitral regurgitation? There are registry data to suggest that they would benefit,” he said, but “we need more data.”

BOSTON – Women with breast cancer who have several tumors in one breast do not necessarily need to have a mastectomy, as new data show a low risk of recurrence at 5 years when they are treated with breast-conserving therapy and radiation.

“[The study] proves the oncologic safety of breast conservation in women with two or three sites of disease, making this a very reasonable option for (previously reluctant) surgeons to present to patients,” first author Kari Rosenkranz, MD, an associate professor at Dartmouth Health in Norwich, Vt., said in an interview.

The findings were presented here at the International Conference on Surgical Cancer Care (SSO 2023), and were published online in the Journal of Clinical Oncology.

Commenting on the study, Hiram S. Cody III, MD, an attending surgeon and professor of surgery at Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center, in New York, said the findings provide valuable new evidence on the issue.

“This is an important study confirming that breast conservation is feasible and safe for women with multiple ipsilateral breast cancers, with excellent results comparable to those for women with unifocal (single site) disease,” he said in an interview.

Although there have been as many as seven previous randomized trials that have shown identical outcomes in survival and local control of disease with breast-conserving therapy versus mastectomy, all those studies excluded patients with more than one site of disease.

At present, many surgeons and guidelines continue to recommend mastectomy for women with multiple-site tumors, based on older data that showed higher recurrence rates.

That is why the new study is so important, Dr. Cody explained. “Here, we see in a prospective trial that breast-conserving therapy is feasible for those with more than one site of disease as well, with high survival and very low rates of local recurrence,” he emphasized.

Dr. Cody noted that “the ideal candidate would be a woman with relatively small tumor size and a breast large enough that the multiple excisions could be performed with a good cosmetic result.”

“We have followed this approach for some time and hope that with the publication of these results more surgeons will recommend this approach for suitable patients,” he said.

The new results were also highlighted in a press release from Mayo Clinic highlighting the Journal of Clinical Oncology publication. Lead author of the article, surgical oncologist Judy Boughey, MD, from the Mayo Clinic in Rochester, Minn., commented: “I am excited about these findings because it will empower patients and the multidisciplinary care teams caring for patients to be thinking about this option for women who may want to preserve their breast.”

This study showed the rate of cancer local recurrence was 3.1%, she noted. This is an excellent outcome and is similar to the local recurrence rate for patients with a single tumor in a breast who had breast-conserving therapy, Dr. Boughey said.

Historically, women with multiple tumors in one breast have been advised to have a mastectomy. Now, patients can be offered a less invasive option with faster recovery, resulting in better patient satisfaction and cosmetic outcomes, she added.


 

Study details

This study, known as the ACOSOG (Alliance) Z11102 trial, was a phase 2 trial conducted in 204 patients enrolled between 2012 and 2016 who had two or three sites of biopsy-proven breast cancer (each site less rhan 5 cm in size, with cN0 or cN1 disease).

These patients were a median age of 61 years, and 83.5% were ER-positive/HER2-negative, 11.5% were HER2-positive, 5.0% were ER-negative/HER2-negative, and 77.5% were node-negative.

All patients were treated with breast conservation surgery, including lumpectomy resected to negative margins, followed by whole breast radiation with a cavity boost to all lumpectomy beds.

With a median follow-up of 66.4 months, six patients developed local recurrence, with five of the recurrences occurring in the ipsilateral breast and one in the chest wall.

For the primary endpoint, the six recurrences represented an estimated cumulative incidence of local recurrence of 3.1% (95% CI, 1.3-6.4), well below the cutoff of 8% that was determined to be the acceptable 5-year local recurrence rate based on historic recurrence rates for unifocal disease, Dr. Rosenkranz explained.

There were no cases of synchronous local and distant recurrences, six contralateral breast cancers, and three new primary nonbreast cancers. Eight patients died, including one related to breast cancer.

There were no significant associations between risk of local recurrence and factors including patient age, number of sites of preoperative biopsy-proven breast cancer, HER2 status, and pathologic T and N category.

In terms of secondary endpoints, 14 patients (7.1%) converted to mastectomy because of positive margins, while 67.6% achieved margin-negative excision in a single operation.

Regarding cosmesis, 70.6% of patients reported good or excellent cosmetic outcomes at 2 years.

In terms of adherence, the whole breast radiation therapy protocol was feasible in most patients.

Of note, among patients without a breast preoperative MRI, the 5-year rate of local recurrence was significantly higher, at 22.6% (n = 14) at 5 years, compared with 1.7% among the 180 patients who did have a preoperative MRI (P = .002). However, Dr. Rosenkranz said these differences should be interpreted with caution.

“We may look at these data and think we should consider preoperative breast MRI in patients who do have known multiple ipsilateral breast cancer, although I think this cohort was certainly much too small to draw definitive conclusions, and this was not a planned secondary endpoint of the trial,” she said during her presentation.
 

Most prefer breast conservation, when possible

Overall, the findings are important considering the array of known benefits of breast conservation over mastectomy, Dr. Rosenkranz concluded.

“The reason this is so important is that we know that patients who undergo breast conservation report improved quality of life, self-esteem, and body image, and therefore it’s incumbent on us as surgeons to expand the indications for breast conservation where we can,” she told the audience.

Speaking with this news organization, she added that the decision-making around breast conservation versus mastectomy can be complicated, and some women do opt for mastectomy because of a variety of factors; therefore, “tailoring therapy to the individual goals and priorities in addition to the disease characteristics is critical.”

That said, she added that “the majority of patients who are eligible for breast conservation do prefer this option.”

Dr. Rosenkranz and Dr. Cody have reported no relevant financial relationships.

This study showed the rate of cancer local recurrence was 3.1%, she noted. This is an excellent outcome and is similar to the local recurrence rate for patients with a single tumor in a breast who had breast-conserving therapy, Dr. Boughey said.

Historically, women with multiple tumors in one breast have been advised to have a mastectomy. Now, patients can be offered a less invasive option with faster recovery, resulting in better patient satisfaction and cosmetic outcomes, she added.


 

Study details

This study, known as the ACOSOG (Alliance) Z11102 trial, was a phase 2 trial conducted in 204 patients enrolled between 2012 and 2016 who had two or three sites of biopsy-proven breast cancer (each site less rhan 5 cm in size, with cN0 or cN1 disease).

These patients were a median age of 61 years, and 83.5% were ER-positive/HER2-negative, 11.5% were HER2-positive, 5.0% were ER-negative/HER2-negative, and 77.5% were node-negative.

All patients were treated with breast conservation surgery, including lumpectomy resected to negative margins, followed by whole breast radiation with a cavity boost to all lumpectomy beds.

With a median follow-up of 66.4 months, six patients developed local recurrence, with five of the recurrences occurring in the ipsilateral breast and one in the chest wall.

For the primary endpoint, the six recurrences represented an estimated cumulative incidence of local recurrence of 3.1% (95% CI, 1.3-6.4), well below the cutoff of 8% that was determined to be the acceptable 5-year local recurrence rate based on historic recurrence rates for unifocal disease, Dr. Rosenkranz explained.

There were no cases of synchronous local and distant recurrences, six contralateral breast cancers, and three new primary nonbreast cancers. Eight patients died, including one related to breast cancer.

There were no significant associations between risk of local recurrence and factors including patient age, number of sites of preoperative biopsy-proven breast cancer, HER2 status, and pathologic T and N category.

In terms of secondary endpoints, 14 patients (7.1%) converted to mastectomy because of positive margins, while 67.6% achieved margin-negative excision in a single operation.

Regarding cosmesis, 70.6% of patients reported good or excellent cosmetic outcomes at 2 years.

In terms of adherence, the whole breast radiation therapy protocol was feasible in most patients.

Of note, among patients without a breast preoperative MRI, the 5-year rate of local recurrence was significantly higher, at 22.6% (n = 14) at 5 years, compared with 1.7% among the 180 patients who did have a preoperative MRI (P = .002). However, Dr. Rosenkranz said these differences should be interpreted with caution.

“We may look at these data and think we should consider preoperative breast MRI in patients who do have known multiple ipsilateral breast cancer, although I think this cohort was certainly much too small to draw definitive conclusions, and this was not a planned secondary endpoint of the trial,” she said during her presentation.
 

Most prefer breast conservation, when possible

Overall, the findings are important considering the array of known benefits of breast conservation over mastectomy, Dr. Rosenkranz concluded.

“The reason this is so important is that we know that patients who undergo breast conservation report improved quality of life, self-esteem, and body image, and therefore it’s incumbent on us as surgeons to expand the indications for breast conservation where we can,” she told the audience.

Speaking with this news organization, she added that the decision-making around breast conservation versus mastectomy can be complicated, and some women do opt for mastectomy because of a variety of factors; therefore, “tailoring therapy to the individual goals and priorities in addition to the disease characteristics is critical.”

That said, she added that “the majority of patients who are eligible for breast conservation do prefer this option.”

Dr. Rosenkranz and Dr. Cody have reported no relevant financial relationships.

HAMBURG, GERMANY – Around 86 billion nerve cells in our brain work together in complex dynamic networks to control almost every sensorimotor and cognitive process. However, the way in which the information is processed in the different regions of the brain is still unclear. There are already some promising approaches to specifically influence the dynamics of neuronal networks to treat neurological and psychiatric diseases.

One of the main topics at the Congress for Clinical Neuroscience of the German Society for Clinical Neurophysiology and Functional Neuroimaging (DGKN), recently held in Hamburg, Germany, was the dynamics of cerebral networks in sensorimotor and cognitive processes, as well as disruptions to network dynamics in neurological and psychiatric diseases.

“We will be unable to develop innovative therapies for widespread neurological and psychiatric diseases until we understand neuronal functions on every level of complexity,” Andreas K. Engel, PhD, director of the Institute for Neurophysiology and Pathophysiology at the University Hospital of Hamburg-Eppendorf, president of the DGKN, and congress president, said during an online press conference.
 

Characterizing states of consciousness

For more than 30 years, it has been known that neuronal signals in the brain are dynamically coupled. Despite intensive research, the functional significance of this coupling on information processing is still largely unknown.

Neuroimaging methods such as electroencephalography (EEG), magnetoencephalography (MEG), structural and functional magnetic resonance imaging (MRI), and electrophysiological examinations were used. Model calculations of the data suggest that dynamic couplings of signals in the cortex play a crucial role in memory performance, thinking processes, and developing perception, among other things.

It has already been shown that the network dynamics of neuronal signals could possibly characterize states of consciousness. Neuronal signals and coupling patterns differ significantly between healthy individuals in a waking state and those who are asleep, under general anesthetic, or in a vegetative state. In Dr. Engel’s view, it may be possible in the future for machine learning algorithms to be used to classify states of consciousness.
 

Changes in brain activity as a biomarker?

The differences in the dynamics of neuronal signals between healthy individuals and patients with psychiatric diseases such as schizophrenia appear much more important for clinical practice. “The characteristic changes in brain activity in the primary auditory cortex could be considered a potential biomarker and used to predict the clinical course of psychiatric diseases, such as psychoses,” reported Dr. Engel.

The gamma-band activity in the auditory cortex could be a potential marker for schizophrenia. According to MEG examinations, the values are decreased both in people at increased risk of psychosis and experiencing first symptoms compared with controls.
 

Activation or inhibition of cerebral networks as new therapeutic approaches

New therapeutic approaches based on the activation or inhibition of cerebral networks are currently areas of intensive research. Close interdisciplinary collaboration between basic science researchers and clinicians is necessary, stressed Dr. Engel. The use of noninvasive brain stimulation is already within reach for the neurorehabilitation of stroke patients. “I am optimistic that in a few years brain stimulation will be established as an integral element of stroke therapy,” said Christian Grefkes-Hermann, MD, PhD, director of the department of neurology at University Hospital of Frankfurt and first vice president of the DGKN.

Despite great advances in acute stroke therapy, many patients must endure permanent deficits in their everyday life, he said. According to Dr. Grefkes-Hermann, rehabilitation procedures often have a dissatisfactory effect, and results greatly vary. He hopes that in the future it may be possible to personalize therapy by using network patterns, thereby improving results.

The aim is to reorganize areas of the brain in which the network activity has been disrupted following a stroke using targeted transcranial magnetic stimulation (TMS). “The most important factor for functional recovery after a stroke is neuronal reorganization,” said Dr. Grefkes-Hermann. With the new methods of neurorehabilitation, network-connectivity disruptions, which are associated with motor function deficits, are first visualized using functional MRI (fMRI).

The imaging or the EEG makes visible the area of the brain that may benefit most from neurostimulation. Subsequently, nerve cells in this region may be precisely stimulated with TMS. Because the healthy hemisphere of the brain is usually overactive after a stroke, there are simultaneous attempts to inhibit the contralesional motor cortex.

Initial results are hopeful. In the initial period after a stroke, TMS can be used in some patients to correct pathological connectivities and thereby improve motor deficits, reported Dr. Grefkes-Hermann. The fMRI pattern can also be used to predict recovery and intervention effects on an individual basis. A phase 3 trial is currently underway of 150 patients who have had a stroke and aims to study the efficacy of the new procedure.
 

Combined TMS and EEG

With the combination of TMS and the simultaneous measurement of EEG activity, a further development of fMRI connectivity analyses is currently being tested. Dr. Grefkes-Hermann believes that this procedure, which is more cost-effective, has higher temporal resolution, can be used directly at the bedside, and has more potential for personalized therapy planning in clinical practice.

The TMS-EEG procedure also makes it possible to predict the risk of post-stroke delirium, which affects around 30% of stroke patients and greatly worsens the outcome, underlined Ulf Ziemann, MD, medical director of the department of neurology at Tübingen (Germany) University Hospital. In a study of 33 patients with acute stroke, the onset of post-stroke delirium could be predicted with a high degree of accuracy by using the TMS-EEG procedure no later than 48 hours after the event.

Other promising, noninvasive methods for neuron activation mentioned by Dr. Ziemann include transcranial focused ultrasound stimulation (tFUS) with low intensity, which is being studied for chronic pain, dementia, epilepsy, traumatic brain injury, and depression, as well as transcranial pulse stimulation (TPS), which is also based on ultrasound. In a pilot study of 35 patients with Alzheimer’s disease, use of TPS within 3 months had positive effects on cognition. However, the study was not controlled and therefore further assessments are needed.
 

Custom deep brain stimulation

For deep brain stimulation (DBS), an established therapy for Parkinson’s disease and other movement disorders, the aim is individualized, symptom-related network stimulation, reported Andrea Kühn, MD, head of the movement disorders and neuromodulation section in the department of neurology at Charité University Hospital Berlin.

At the panregional collaborative research center ReTune, which has been supported for 4 years now by €10 million from the German Research Foundation (DFG), imaging and computer-assisted programming algorithms are being developed for DBS. They will greatly simplify the time-consuming standard procedure for the best possible setting of the stimulation parameters, which requires a hospital stay of several days.

A randomized crossover study of 35 patients with Parkinson’s disease proved the equivalence of the fast, algorithm-assisted DBS for the control of motor symptoms compared with standard procedures.

The new methods have the potential to considerably improve the outcome of patients with neurological and psychiatric diseases, according to scientists. However, the positive data must still be validated in further studies.

DENVER – Adding therapies such as acupuncture, electrophysical stimulation, or other interventions to standard exercise therapy does not appear to offer much benefit in pain relief or physical function for patients with knee osteoarthritis, according to a study presented at the OARSI 2023 World Congress. The findings were also published in the Cochrane Database of Systematic Reviews in October 2022.

“The results do not support the use of adjunctive therapies when we add them to exercise for pain, physical function, or quality of life, when compared against placebo, adjunctive therapy, and exercise,” Helen P. French, PhD, told attendees at the meeting sponsored by the Osteoarthritis Research Society International. The findings were similar for pain and physical function when comparing adjunctive therapies with exercise against exercise alone, said Dr. French, an associate professor in physiotherapy at the Royal College of Surgeons, Dublin, except that patients using adjunctive therapies reported feeling greater improvement in their global assessments.

Exercise is recommended as a core treatment for osteoarthritis, but some patients or clinicians may be interested in supplementing that therapy with acupuncture, heat therapy, electromagnetic fields, transcutaneous electrical nerve stimulation, braces/orthotics, and other interventions. Various Cochrane Reviews of the evidence exist for these interventions in treating chronic pain in general but not for their use as adjunctive therapies in addition to exercise for osteoarthritis pain.

Researchers therefore assessed the evidence for improvement in pain, physical function, and quality of life for two sets of comparisons: adjunctive therapies plus exercise versus exercise alone, and adjunctive therapies with exercise versus placebo adjunctive therapy with exercise. The review excluded studies looking at medications or supplements.

Pain was assessed with the Numeric Pain Rating Scale (NPRS, 0-10), with an improvement of at least 2 points (15% improvement) representing the minimum clinically important difference (MCID). Physical function was assessed with the Western Ontario and McMaster Universities Arthritis Index (WOMAC, 0-68), with 6 points (15%) considered the MCID, and quality of life was assessed with the SF-36 (0-100), with 6 points (12%) as the MCID.

The researchers identified trials on knee osteoarthritis that included an overall 6,508 participants with an average age ranging from 52 to 83 years. A total of 36 studies evaluated electrophysical agents. Another seven looked at manual therapies; four looked at acupuncture/dry needling or taping; three looked at psychological, dietary, or “whole body vibration” therapies; and two evaluated spa or peloid therapy. Only one trial evaluated foot insoles.

Nearly all the studies (98%) assessed pain, and most (87%) assessed physical function. Only about one in five (21%) assessed quality of life. The improvement in pain from adding adjunctive therapies to exercise, compared with placebo therapies plus exercise, was 0.77 points, or just under a 10% improvement, which fell short of the 15% MCID. Physical function improvement similarly fell short, with an average improvement of 5 points (12%).

In comparisons of exercise plus adjunctive therapies against exercise alone, the improvement from the additional interventions was even lower. Pain improvement was 0.41 points (7%), and physical function improvement was 2.8 points (9%). However, patients’ perceptions told a different story: 37% more patients who were using an adjunctive therapy reported feeling that the therapies were successful, compared with patients undergoing exercise therapy alone.

Adverse events were poorly reported in the trials, with only 10 trials reporting them at all, and the researchers found no significant difference in adverse events among the studies reporting them. The most common adverse events were increased pain in the joint with the osteoarthritis, pain elsewhere, or swelling and inflammation. It’s unclear, however, whether the pain, swelling, and inflammation were related to the interventions and how serious these effects might have been.

Michelle Hall, PhD, an associate professor in the department of physiotherapy at the University of Melbourne, comoderated the session with this presentation and found it interesting that more than one-third of patients perceived that they did better with the additional therapies even though improvement didn’t bear out in their pain or physical function assessments.

“But the other part of that was that the studies were of poor quality, so we can’t say with confidence, ‘Don’t do this therapy because it’s not going to work,’ ” Dr. Hall said in an interview. She said she personally would probably discourage patients from those therapies, “but I don’t think the evidence is there for everybody to do that,” she added.

Martin Van Der Esch, PhD, of Reade Centre of Rehabilitation and Rheumatology in Amsterdam, also comoderated the discussion and had more concerns about the use of adjunctive therapies in light of the study’s findings. He said in an interview that he tended to believe the patients’ overall self-reported improvement is likely a placebo effect, and he sees potential harm in that effect. If the pain is not truly decreasing as patients continue using those therapies, then the pain may become a more stable part of the nervous system, “so I think they need to do an intervention which really has evidence in reducing pain, an active approach that means exercising in the right way,” Dr. Van Der Esch said. If patients are undergoing therapy whose primary benefit is a placebo effect, “the pain will prolong and become more fixed in the nervous system,” shifting the patients toward greater risk of the pain becoming chronic, he said.

“I want to emphasize that we have an ethical role to our management, and it’s not ethical to give treatments which have no response and no pain relief except that the patient or the professional believes it will have an effect,” Dr. Van Der Esch said.

The research did not involve outside funding. Dr. French, Dr. Hall, and Dr. Van Der Esch reported having no relevant financial relationships.

If the pain is not truly decreasing as patients continue using those therapies, then the pain may become a more stable part of the nervous system, “so I think they need to do an intervention which really has evidence in reducing pain, an active approach that means exercising in the right way,” Dr. Van Der Esch said. If patients are undergoing therapy whose primary benefit is a placebo effect, “the pain will prolong and become more fixed in the nervous system,” shifting the patients toward greater risk of the pain becoming chronic, he said.

“I want to emphasize that we have an ethical role to our management, and it’s not ethical to give treatments which have no response and no pain relief except that the patient or the professional believes it will have an effect,” Dr. Van Der Esch said.

The research did not involve outside funding. Dr. French, Dr. Hall, and Dr. Van Der Esch reported having no relevant financial relationships.

DENVER – Adding therapies such as acupuncture, electrophysical stimulation, or other interventions to standard exercise therapy does not appear to offer much benefit in pain relief or physical function for patients with knee osteoarthritis, according to a study presented at the OARSI 2023 World Congress. The findings were also published in the Cochrane Database of Systematic Reviews in October 2022.

“The results do not support the use of adjunctive therapies when we add them to exercise for pain, physical function, or quality of life, when compared against placebo, adjunctive therapy, and exercise,” Helen P. French, PhD, told attendees at the meeting sponsored by the Osteoarthritis Research Society International. The findings were similar for pain and physical function when comparing adjunctive therapies with exercise against exercise alone, said Dr. French, an associate professor in physiotherapy at the Royal College of Surgeons, Dublin, except that patients using adjunctive therapies reported feeling greater improvement in their global assessments.

Exercise is recommended as a core treatment for osteoarthritis, but some patients or clinicians may be interested in supplementing that therapy with acupuncture, heat therapy, electromagnetic fields, transcutaneous electrical nerve stimulation, braces/orthotics, and other interventions. Various Cochrane Reviews of the evidence exist for these interventions in treating chronic pain in general but not for their use as adjunctive therapies in addition to exercise for osteoarthritis pain.

Researchers therefore assessed the evidence for improvement in pain, physical function, and quality of life for two sets of comparisons: adjunctive therapies plus exercise versus exercise alone, and adjunctive therapies with exercise versus placebo adjunctive therapy with exercise. The review excluded studies looking at medications or supplements.

Pain was assessed with the Numeric Pain Rating Scale (NPRS, 0-10), with an improvement of at least 2 points (15% improvement) representing the minimum clinically important difference (MCID). Physical function was assessed with the Western Ontario and McMaster Universities Arthritis Index (WOMAC, 0-68), with 6 points (15%) considered the MCID, and quality of life was assessed with the SF-36 (0-100), with 6 points (12%) as the MCID.

The researchers identified trials on knee osteoarthritis that included an overall 6,508 participants with an average age ranging from 52 to 83 years. A total of 36 studies evaluated electrophysical agents. Another seven looked at manual therapies; four looked at acupuncture/dry needling or taping; three looked at psychological, dietary, or “whole body vibration” therapies; and two evaluated spa or peloid therapy. Only one trial evaluated foot insoles.

Nearly all the studies (98%) assessed pain, and most (87%) assessed physical function. Only about one in five (21%) assessed quality of life. The improvement in pain from adding adjunctive therapies to exercise, compared with placebo therapies plus exercise, was 0.77 points, or just under a 10% improvement, which fell short of the 15% MCID. Physical function improvement similarly fell short, with an average improvement of 5 points (12%).

In comparisons of exercise plus adjunctive therapies against exercise alone, the improvement from the additional interventions was even lower. Pain improvement was 0.41 points (7%), and physical function improvement was 2.8 points (9%). However, patients’ perceptions told a different story: 37% more patients who were using an adjunctive therapy reported feeling that the therapies were successful, compared with patients undergoing exercise therapy alone.

Adverse events were poorly reported in the trials, with only 10 trials reporting them at all, and the researchers found no significant difference in adverse events among the studies reporting them. The most common adverse events were increased pain in the joint with the osteoarthritis, pain elsewhere, or swelling and inflammation. It’s unclear, however, whether the pain, swelling, and inflammation were related to the interventions and how serious these effects might have been.

Michelle Hall, PhD, an associate professor in the department of physiotherapy at the University of Melbourne, comoderated the session with this presentation and found it interesting that more than one-third of patients perceived that they did better with the additional therapies even though improvement didn’t bear out in their pain or physical function assessments.

“But the other part of that was that the studies were of poor quality, so we can’t say with confidence, ‘Don’t do this therapy because it’s not going to work,’ ” Dr. Hall said in an interview. She said she personally would probably discourage patients from those therapies, “but I don’t think the evidence is there for everybody to do that,” she added.

Martin Van Der Esch, PhD, of Reade Centre of Rehabilitation and Rheumatology in Amsterdam, also comoderated the discussion and had more concerns about the use of adjunctive therapies in light of the study’s findings. He said in an interview that he tended to believe the patients’ overall self-reported improvement is likely a placebo effect, and he sees potential harm in that effect.

DENVER – Using antidepressants to treat osteoarthritis pain can benefit some individuals but appears to have a clinically unimportant reduction in pain when looking at all patients who have tried them, according to a study presented at the OARSI 2023 World Congress. The review was also published in the Cochrane Database of Systematic Reviews in October 2022.

In terms of implications for clinical practice, the findings “seem to suggest there is a subgroup that is more likely to respond to antidepressants,” Anita Wluka, PhD, MBBS, a professor in the School of Public Health and Preventive Medicine at Monash University in Melbourne, told attendees. The findings also raise an important research question: “How can we identify the patient phenotype likely to benefit so we can [minimize the] risk of those adverse events and effects?”

Osteoarthritis pain is heterogeneous, and an estimated 30% of the pain is neuropathic-like, likely including central and peripheral sensitization, Dr. Wluka said. Given that antidepressants affect multiple sites along these pathways, multiple organizations have issued a conditional recommendation for duloxetine in their osteoarthritis guidelines, including OARSI, the European Alliance of Associations for Rheumatology, and the American College of Rheumatology.

The Cochrane Collaboration therefore conducted a systematic review and meta-analysis of research on the benefits and harms of using antidepressants to treat symptomatic knee and hip osteoarthritis. The review included studies through January 2021 whose participants had knee and/or hip osteoarthritis and which compared antidepressant therapy with placebo or another intervention for at least 6 weeks. The authors looked at seven outcomes: overall pain on a 0-10 scale, clinical response (at least a 50% reduction in 24‐hour mean pain), physical function using the Western Ontario and McMaster Universities Arthritis Index (WOMAC), quality of life using the EQ-5D, the proportion of participants withdrawing because of adverse events, the proportion who experienced any adverse events, and the proportion who experienced serious adverse events.

The researchers considered a change on the pain scale of 0.5-1 points to be “slight to small,” a difference above 1 up to 2 to be “moderate,” and a difference greater than 2 points to be “large.” In assessing quality of life function on a scale of 0-100, a slight to small difference was 5-10, a moderate difference was 11-20, and a large difference was above 20.

Of the 18 articles the researchers identified for qualitative synthesis, 9 met the criteria for qualitative synthesis in the meta-analysis, including 7 studies only on the knee and 2 that included the knees and hips. All nine studies compared antidepressants with placebo, with or without NSAIDs. Most focused on serotonin and norepinephrine reuptake inhibitors (SNRIs) – six studies on duloxetine and one on milnacipran – while one included fluvoxamine and one included nortriptyline.

The trials included a combined 2,122 participants who were predominantly female with an average age range of 54-66. Trials ranged from 8 to 16 weeks. Five of the trials carried risk of attrition and reporting bias, and only one trial had low risk of bias across all domains.

In five trials with SNRIs and one trial with tricyclics (nortriptyline) totaling 1,904 participants, 45% of those receiving antidepressants had a clinical response, compared with 29% of patients who received placebo (risk ratio, 1.55; 95% CI, 1.31-1.92). This absolute improvement in pain occurred in 16% more participants taking antidepressants, giving a number needed to treat (NNT) of 6. Average improvement in WOMAC physical function was 10.5 points with placebo and 16.2 points with antidepressants, indicating a “small, clinically unimportant response,” the researchers concluded.

Withdrawals because of adverse events included 11% of the antidepressant group and 5% of the placebo group (RR, 2.15; 95% CI, 1.56-2.87), putting the NNT for a harmful outcome at 17.

For all nine trials together, however, the mean reduction in pain from antidepressants was 2.3 points, compared with 1.7 points with placebo, a statistically significant but ”clinically unimportant improvement,” the researchers concluded. Adverse events occurred in 64% of the antidepressant group, compared with 49% of the placebo group (RR, 1.27; 95% CI, 1.15-1.41), which put the NNT for a harmful outcome at 7. No significant difference in serious adverse events occurred between the groups.

The analysis was limited by the low number of trials, most of which were sponsored by industry and most of which used duloxetine. Further, few of the studies enrolled patients with osteoarthritis of the hip, none assessed medium- or long-term effects, and none stratified the participants for different types of pain (neuropathic-like or central or peripheral pain sensitization).

“My general impression is that there was a statistically significant difference found in favor of duloxetine and the antidepressants,” David J. Hunter, MBBS, PhD, MSc, of the University of Sydney, said after the presentation. “There is a real risk of harm, which I think is important to take into consideration, but at least for me as a clinician and in advising other clinicians, it’s one tool in our armamentarium. I think it’s really important to allow patients to make an informed decision about the potential benefit, the real risk of harm, and the fact that it is quite useful in some patients, and I use it in my clinical practice.”

Jeffrey N. Katz, MD, MS, of Brigham and Women’s Hospital in Boston, said he uses antidepressants in the same way in his practice and that other types of medications, such as TNF inhibitors, also carry risk of harm that may exceed that of antidepressants.

“I’ve had lots of people start duloxetine, and if they stop it, it’s usually because they just don’t tolerate it very well,” Dr. Katz said.

“We don’t want to throw too many things away,” Dr. Hunter added. “Our patients don’t necessarily have a lot of choices here from a pharmacologic perspective, so I think it’s one of those options that I want to keep in my tool kit, and that’s not necessarily going to change.”

The research did not involve outside funding, and Dr. Wluka reported having no industry disclosures. Disclosure information was unavailable for Dr. Katz and Dr. Hunter. The Congress was sponsored by the Osteoarthritis Research Society International.

NEW ORLEANS – Limited treatment options exist for brittle nail syndrome, a heterogeneous abnormality characterized by increased nail plate fragility, with nails that split, flake, crumble, and become soft and lose elasticity.

“The mainstay of treatment is irritant avoidance and moisturization,” Shari R. Lipner, MD, PhD, associate professor of clinical dermatology and director of the nail division at Weill Cornell Medicine, New York, said at the annual meeting of the American Academy of Dermatology. “This works well if patients are religious about doing it.”

Dr. Lipner

Brittle nail syndrome affects about 20% of adults, she said, and is more common in females, particularly those older than age 50. Most cases are idiopathic, but some are secondary to dermatologic diseases including nail psoriasis and nail lichen planus, and systemic diseases such as hyperthyroidism and hypothyroidism. They are more common in patients in certain occupations such as carpentry. “The pathogenesis is poorly understood but is thought to be due to weakened intercellular keratinocyte bridges, decreased cholesterol sulphate in the nail plate, and reduced water content in the nail plate,” Dr. Lipner said.

Key clinical findings include onychoschizia (peeling of the nail plate), onychorrhexis (an increase in the longitudinal ridges and furrows, sometimes leading to splitting), and superficial granulation of keratin. Treatment involves general measures. “You want to treat the underlying cause and recommend that the patient avoid water and irritant exposure,” she said. Her general instructions for affected patients are to wear latex gloves for wet work and cotton gloves for dry work, avoid triclosan-based hand sanitizers, avoid nail cosmetics, minimize nail trauma, and foster moisturization.“It’s important to give these instructions verbally and in written form,” she said. “In our practice, we designed a QR code that links to our patient handout.”

According to Dr. Lipner, the promotion of vitamins and supplements such as biotin, vitamin D, amino acids, and chromium for treating brittle nail syndrome is rampant on the Internet and on social media, but no rigorously designed clinical trials have shown efficacy for any of them. “Very few people are deficient in biotin, except for those with inherited enzyme deficiencies,” and most people “can get all the biotin they need from a regular diet,” she said.

The initial rationale for using biotin for nails comes from the veterinary literature, she continued. In the 1940s, chickens with biotin deficiency developed fissures in their feet and parrot-like beaks. In the 1970s, pigs with biotin deficiency developed friable hooves, which was corrected with biotin supplementation. “By the 1980s it was standard practice to supplement the feet of pigs with biotin,” she said.

In a human trial from 1989, German researchers enrolled 71 patients with brittle nail syndrome who took oral biotin, 2.5 mg daily. Of the 45 patients evaluated, 41 (91%) showed improvement in firmness and hardness of the fingernails over the course of 5.5 months, but there was no good control group, Dr. Lipner said. In a follow-up study, the same German researchers used scanning electron microscopy to evaluate 22 patients with brittle nails who took oral biotin 2.5 mg daily and compared them with 10 patients with normal nails who did not take biotin. They found a 25% increase in nail plate thickness in the biotin group and onychoschizia resolved in 50% of patients who received biotin. “But again, there was no good control group,” Dr. Lipner said.

In a third study on the topic, researchers surveyed 46 patients who presented with onychorrhexis and/or onychoschizia on clinical exam and took 2.5 mg of biotin daily. Of the 35 survey respondents, 63% subjectively reported improvement in their nails at a mean of 2 months. “This is where we are today: There have been studies of only 80 patients that were done 25 years ago,” Dr. Lipner said. “That’s all of our evidence for biotin for the treatment of brittle nail syndrome.”
 

FDA warning about biotin

Additional cause for concern, she continued, is the safety communication issued by the FDA in 2017, stating that the use of biotin may interfere with certain lab tests such as thyroid tests and cardiac enzymes, in some cases leading to death. The safety communication was updated in 2019.

In 2018, Dr. Lipner and colleagues administered an anonymous survey to 447 patients at their clinic asking about their use of biotin supplements. Of the 447 patients, 34% reported current use of biotin. Among biotin users, 7% were aware of the FDA warning, 29% of respondents reported that it was recommended by either a primary care physician or a dermatologist, and 56% underwent laboratory testing while taking biotin. “It’s our duty to warn our patients about the evidence for biotin for treating brittle nails, and about this interference on laboratory tests,” Dr. Lipner said.

Other treatment options for brittle nail syndrome include two lacquers that are available by prescription. One contains hydroxypropyl chitosan, Equisetum arvense, and methylsulphonylmethane; the other contains 16% poly-ureaurethane, but has not been well studied. “These products can be very expensive if not covered by insurance,” Dr. Lipner said.

As an alternative, she recommends Nail Tek CITRA 2 Nail Strengthener, which is available for less than $10 from Walmart and other retailers.

Cyclosporine emulsion also has been studied for brittle nail syndrome, but results to date have been underwhelming. Dr. Lipner and colleagues are exploring the effect of platelet rich plasma for treating brittle nails on the premise that it will improve nail growth and promote healing, in a 16-week trial that has enrolled 10 patients and includes both a Physician Global Improvement Assessment (PGIA) and a Physician Global Assessment (PGA) score. “Our data is being analyzed by three independent nail experts, and we hope to report the findings next year,” she said.

Dr. Lipner reported having no disclosures relevant to her presentation.

In a third study on the topic, researchers surveyed 46 patients who presented with onychorrhexis and/or onychoschizia on clinical exam and took 2.5 mg of biotin daily. Of the 35 survey respondents, 63% subjectively reported improvement in their nails at a mean of 2 months. “This is where we are today: There have been studies of only 80 patients that were done 25 years ago,” Dr. Lipner said. “That’s all of our evidence for biotin for the treatment of brittle nail syndrome.”
 

FDA warning about biotin

Additional cause for concern, she continued, is the safety communication issued by the FDA in 2017, stating that the use of biotin may interfere with certain lab tests such as thyroid tests and cardiac enzymes, in some cases leading to death. The safety communication was updated in 2019.

In 2018, Dr. Lipner and colleagues administered an anonymous survey to 447 patients at their clinic asking about their use of biotin supplements. Of the 447 patients, 34% reported current use of biotin. Among biotin users, 7% were aware of the FDA warning, 29% of respondents reported that it was recommended by either a primary care physician or a dermatologist, and 56% underwent laboratory testing while taking biotin. “It’s our duty to warn our patients about the evidence for biotin for treating brittle nails, and about this interference on laboratory tests,” Dr. Lipner said.

Other treatment options for brittle nail syndrome include two lacquers that are available by prescription. One contains hydroxypropyl chitosan, Equisetum arvense, and methylsulphonylmethane; the other contains 16% poly-ureaurethane, but has not been well studied. “These products can be very expensive if not covered by insurance,” Dr. Lipner said.

As an alternative, she recommends Nail Tek CITRA 2 Nail Strengthener, which is available for less than $10 from Walmart and other retailers.

Cyclosporine emulsion also has been studied for brittle nail syndrome, but results to date have been underwhelming. Dr. Lipner and colleagues are exploring the effect of platelet rich plasma for treating brittle nails on the premise that it will improve nail growth and promote healing, in a 16-week trial that has enrolled 10 patients and includes both a Physician Global Improvement Assessment (PGIA) and a Physician Global Assessment (PGA) score. “Our data is being analyzed by three independent nail experts, and we hope to report the findings next year,” she said.

Dr. Lipner reported having no disclosures relevant to her presentation.

NEW ORLEANS – Limited treatment options exist for brittle nail syndrome, a heterogeneous abnormality characterized by increased nail plate fragility, with nails that split, flake, crumble, and become soft and lose elasticity.

“The mainstay of treatment is irritant avoidance and moisturization,” Shari R. Lipner, MD, PhD, associate professor of clinical dermatology and director of the nail division at Weill Cornell Medicine, New York, said at the annual meeting of the American Academy of Dermatology. “This works well if patients are religious about doing it.”

Dr. Lipner

Brittle nail syndrome affects about 20% of adults, she said, and is more common in females, particularly those older than age 50. Most cases are idiopathic, but some are secondary to dermatologic diseases including nail psoriasis and nail lichen planus, and systemic diseases such as hyperthyroidism and hypothyroidism. They are more common in patients in certain occupations such as carpentry. “The pathogenesis is poorly understood but is thought to be due to weakened intercellular keratinocyte bridges, decreased cholesterol sulphate in the nail plate, and reduced water content in the nail plate,” Dr. Lipner said.

Key clinical findings include onychoschizia (peeling of the nail plate), onychorrhexis (an increase in the longitudinal ridges and furrows, sometimes leading to splitting), and superficial granulation of keratin. Treatment involves general measures. “You want to treat the underlying cause and recommend that the patient avoid water and irritant exposure,” she said. Her general instructions for affected patients are to wear latex gloves for wet work and cotton gloves for dry work, avoid triclosan-based hand sanitizers, avoid nail cosmetics, minimize nail trauma, and foster moisturization.“It’s important to give these instructions verbally and in written form,” she said. “In our practice, we designed a QR code that links to our patient handout.”

According to Dr. Lipner, the promotion of vitamins and supplements such as biotin, vitamin D, amino acids, and chromium for treating brittle nail syndrome is rampant on the Internet and on social media, but no rigorously designed clinical trials have shown efficacy for any of them. “Very few people are deficient in biotin, except for those with inherited enzyme deficiencies,” and most people “can get all the biotin they need from a regular diet,” she said.

The initial rationale for using biotin for nails comes from the veterinary literature, she continued. In the 1940s, chickens with biotin deficiency developed fissures in their feet and parrot-like beaks. In the 1970s, pigs with biotin deficiency developed friable hooves, which was corrected with biotin supplementation. “By the 1980s it was standard practice to supplement the feet of pigs with biotin,” she said.

In a human trial from 1989, German researchers enrolled 71 patients with brittle nail syndrome who took oral biotin, 2.5 mg daily. Of the 45 patients evaluated, 41 (91%) showed improvement in firmness and hardness of the fingernails over the course of 5.5 months, but there was no good control group, Dr. Lipner said. In a follow-up study, the same German researchers used scanning electron microscopy to evaluate 22 patients with brittle nails who took oral biotin 2.5 mg daily and compared them with 10 patients with normal nails who did not take biotin. They found a 25% increase in nail plate thickness in the biotin group and onychoschizia resolved in 50% of patients who received biotin. “But again, there was no good control group,” Dr. Lipner said.

NEW ORLEANS – The oral Janus kinase (JAK) inhibitor ivarmacitinib, which is characterized as being highly selective for the JAK1 enzyme, is effective for the treatment of atopic dermatitis (AD), according to a phase 3 multinational trial presented as a late-breaker at the annual meeting of the American Academy of Dermatology.

Two doses were studied in the placebo-controlled trial and both demonstrated “a favorable benefit-to-risk profile in patients with moderate to severe AD,” reported Yan Zhao, MD, a clinician and researcher in the department of dermatology, Peking University People’s Hospital, Beijing.

In the study, called QUARTZ3, 336 patients aged 12 and older at 51 sites in China and Canada were randomized to 4 mg once-daily ivarmacitinib, 8 mg once-daily QD ivarmacitinib, or placebo. The mean age of the population was 32 years and approximately one-third were female.

The mean duration of AD for participants was 10 years. The mean baseline Eczema Area and Severity Index (EASI) score was near 30. On the Investigator Global Assessment (IGA) tool, approximately 40% had a score of 4, which is the highest score on the scale and indicates severe disease. The remaining patients had an IGA score of 3.

The co-primary endpoints were change in IGA and EASI scores at 16 weeks, and both improved rapidly, showing statistical significance relative to placebo by 4 weeks with no plateauing effect at the end of the 16-week trial. By week 16, the proportion of patients with an EASI score of 75, signifying a 75% improvement, was 66%, 54%, and 22% for the 8-mg dose of ivarmacitinib, 4-mg dose of ivarmacitinib, and placebo groups (P < .001 versus placebo for both doses of active therapy), respectively.

The pattern of the IGA response was similar. By week 16, the proportion of patients achieving an IGA score of 0 (clear) or 1 (almost clear) was 42%, 36%, and 9% for the 8-mg dose of ivarmacitinib, 4-mg dose of ivarmacitinib, and placebo groups, respectively. The advantage of either dose over placebo was highly significant (P < .001) at 8, 12, and 16 weeks.

For the WI-NRS (Worst Itch – Numeric Rating Scale), the advantage of the 8-mg dose relative to placebo was significant (P < .001) at the 1-week evaluation. By 2 weeks, the 4-mg dose had gained the same degree of statistical significance relative to placebo. After week 4, when the maximum proportion of patients with a WI-NRS score ≤ 4 was reached (50%, 35%, and 10% in the 8-mg, 4-mg, and placebo groups), and the relative advantage of active treatment persisted until the end of the 16-week study.

Two scales were used to evaluate change in quality of life. On the DLQI (Dermatology Life Quality Index) and POEM (Patient-Oriented Eczema Measure), improvements were again rapid and sustained. By week 4, improvement with the 8-mg dose was about fourfold greater (P < .001) than improvement with placebo for DLQI and about sixfold greater (P < .001) for POEM. For the 4-mg dose, the relative differences were approximately threefold and fourfold greater, and both were significant (P <.001).

There was no further gain in these quality-of-life scales from week 4 to week 16, but the advantages relative to placebo were generally sustained, Dr. Zhao reported.

Ivarmacitinib was safe and well-tolerated, according to Dr. Zhao. The proportion of patients with a treatment-emergent adverse event that led to drug discontinuation was numerically higher (5.4%) in the placebo group than in the 8-mg (3.6%) or 4-mg group (2.7%). Rates of infection in the three groups were similar, and there were no major adverse cardiovascular events (MACE) or thromboembolism observed in any group.

Ivarmacitinib, which has about a 10-fold greater selectivity for JAK1 than JAK2 and a more than 70-fold greater selectivity for JAK1 than JAK3, is being tested for rheumatoid arthritis, inflammatory bowel disease, and alopecia areata in addition to AD, Dr. Zhao said. She also reported that an application for new drug approval has been submitted in China. Efforts to pursue regulatory approval elsewhere are anticipated.

Currently, there are three JAK inhibitors licensed for the treatment of AD in the United States. Upadacitinib (Rinvoq) and abrocitinib (Cibinqo) are also once-daily oral JAK1-selective inhibitors. Regulatory approval for AD by the Food and Drug Administration was granted to both in early 2022 and both now have an indication for moderate to severe disease in patients ages 12 years and older.

In September 2021, the first U.S. approval of a drug in this class for AD was granted for a topical formulation of ruxolitinib (Opzelura), which has selectivity for both JAK1 and JAK2. The indication is for mild to moderate AD in patients aged 12 years and older.

In the phase 3 clinical trial that led to approval of abrocitinib for AD, the comparator groups included placebo and active treatment with 300 mg dupilumab administered subcutaneously every other week. The higher of two doses of abrocitinib (100 mg) was numerically superior to dupilumab in terms of EASI 75 response at week 12 and was statistically superior for relief of itch at week 2.

Relative to the first-generation JAK inhibitor tofacitinib (Xeljanz), both of the approved oral JAK inhibitors for AD, abrocitinib and upadacitinib, have greater JAK1-selectivity. However, selectivity for all JAK inhibitors is relative rather than absolute, according to a recent review article on oral JAK inhibitors for AD. Efficacy and safety are likely determined by relative inhibition of each of the four JAK enzymes (JAK1, JAK2, JAK3, and TYK2). Although JAK1 appears to be an important target for AD treatment, the clinical significance of the degree of selectivity among oral JAK inhibitors is not yet clear.

In an interview, the senior author of that review article, Emma Guttman-Yassky, MD, PhD, emphasized this point. She said there is no evidence and no basis on which to speculate that any one drug in this class is better than another for AD. Dr. Guttman-Yassky is a professor and system chair of dermatology and immunology at the Icahn School of Medicine at Mount Sinai, New York.

“The efficacy [of ivarmacitinib] seems, in general, to be in line with other JAK inhibitors,” said Dr. Guttman-Yassky, who attended the late-breaker session during which these data were presented. Although she acknowledged that rapid control of pruritus is important clinically, she said the speed of itch relief as reported in the phase 3 ivarmacitinib trial does not distinguish it from other oral drugs in the class.

Shawn Kwatra, MD, director of the Johns Hopkins Itch Center, Johns Hopkins University, Baltimore, agreed.

“The rapid effects on itch of ivarmacitinib are consistent with those observed by the already approved JAK1-selective inhibitors abrocitinib and upadacitinib,” he said in an interview.

This suggests that head-to-head trials will be needed to draw any conclusions about the relative efficacy and safety of existing and emerging oral JAK inhibitors for AD.

Dr. Zhao has reported a financial relationship with Reistone Biopharma, which is developing ivarmacitinib and provided funding for the trial. Dr. Guttman-Yassky has reported financial relationships with more than 20 pharmaceutical companies, including companies that make JAK inhibitors. Dr. Kwatra has reported financial relationships with AbbVie, Aslan, Arcutis Biotherapeutics, Castle Biosciences, Celldex, Galderma, Genzada, Incyte, Johnson & Johnson, Leo Pharma, Novartis, Pfizer, Regeneron, and Sanofi.

Among patients who undergo forceps-assisted vaginal delivery, obesity does not appear to be associated with increased risk for complications such as injuries to the anal sphincter or the need for their babies to be admitted to the neonatal intensive care unit, researchers have found.

But obesity does appear to increase the chances that when physicians attempt operative vaginal delivery with either forceps or a vacuum, patients will wind up undergoing cesarean delivery, another study found.

Taken together, the new data may help inform physicians’ decisions about when to consider operative vaginal delivery as an alternative to emergency cesarean births.

A prospective study showed that failed operative vaginal delivery – that is, a cesarean delivery after an attempted operative vaginal delivery – occurred for 10.1% of patients with obesity and 4.2% of those without obesity.

Researchers presented the findings at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“We want to really try to reduce the rate of C-sections and primary cesarean deliveries. One of the ways to do that is to attempt operative vaginal delivery,” said Marissa Platner, MD, assistant professor of maternal-fetal medicine at Emory University School of Medicine, Atlanta, who was not involved in the new research.

Data on how obesity influences risks with operative vaginal delivery have been limited and mixed, the researchers said.

To examine how often attempted operative vaginal delivery fails in patients with obesity, Jennifer Grasch, MD, a maternal-fetal medicine fellow at the Ohio State University Wexner Medical Center, Columbus, and her colleagues conducted a secondary analysis of data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, which included more than 10,000 participants.

“We know that cesarean sections among people with obesity are associated with increased complications, such as higher rates of infection and wound complications, than for people with lower BMI,” Dr. Grasch said. “Operative vaginal delivery can be an alternative to cesarean delivery in some situations, so we were interested in whether attempted operative vaginal delivery was also associated with higher rates of complications in individuals with obesity than those without obesity.”

The researchers focused on 791 patients with an attempted operative vaginal delivery. About 40% had a BMI of 30 or greater. Clinicians used a vacuum in approximately 60% of the attempts.

After an attempted vacuum-assisted delivery, neonatal morbidity was more common for infants whose mothers had obesity than for those whose mothers did not (32.7% vs. 22.3%; adjusted odds ratio, 1.61 [1.07-2.43]). Neonatal morbidity did not differ by obesity status following forceps-attempted delivery. Other adverse outcomes, including measures of maternal morbidity, did not significantly differ by obesity status, according to the researchers.
 

Choice may come down to experience

Several factors influence whether a clinician chooses forceps- or vacuum-assisted delivery or cesarean delivery, “but one of the most important is experience,” Dr. Grasch said. “Complication rates with both forms of operative vaginal delivery are low, yet there has been a trend toward lower rates of both in the last few decades.”

Elizabeth Cochrane, MD, a maternal-fetal medicine fellow at Mount Sinai Hospital, New York, and her colleagues investigated the relationship between obesity and adverse outcomes among patients with forceps-assisted vaginal deliveries.

The researchers analyzed data from 897 patients who underwent a forceps-assisted vaginal delivery between 2017 and 2021; 29% had a BMI of 30 or greater.

Injuries to the anal sphincter – which can lead to fecal incontinence – occurred in 18.7% of patients without obesity and in 17.7% of those with obesity. Admission to the neonatal intensive care unit occurred in 11.5% of patients without obesity and in 12.3% of patients with obesity. The differences were not statistically significant.

The bottom line: For forceps-assisted vaginal delivery, “obesity does not appear to be associated with increased rates” of adverse outcomes for mothers or newborns, the researchers concluded.
 

Reassuring data

The study by Dr. Cochrane’s group “provides helpful information for providers to be reassured when they are performing forceps deliveries” for patients with obesity, Dr. Platner said.

Rates of obesity have risen in the United States, and physicians often wonder whether a patient with obesity could be a candidate for forceps-assisted delivery, Dr. Cochrane said. In 2019, 29% of women had obesity before becoming pregnant.

“It all really comes down to how comfortable the provider is in that skill set and also the overall clinical scenario,” she said. “Sometimes an operative delivery with forceps or a vacuum can be the fastest way to deliver a baby when there is acute concern for maternal decompensation or fetal decompensation.”

The alternative is an emergency cesarean delivery. Given that those operations can be riskier and more difficult for patients with higher BMIs, a forceps-assisted delivery may be “an interesting alternative to emergency caesarean sections, as long as it is in an appropriate clinical setting with providers who feel very confident and comfortable using those devices,” Dr. Cochrane said.

Among patients who undergo forceps-assisted vaginal delivery, obesity does not appear to be associated with increased risk for complications such as injuries to the anal sphincter or the need for their babies to be admitted to the neonatal intensive care unit, researchers have found.

But obesity does appear to increase the chances that when physicians attempt operative vaginal delivery with either forceps or a vacuum, patients will wind up undergoing cesarean delivery, another study found.

Taken together, the new data may help inform physicians’ decisions about when to consider operative vaginal delivery as an alternative to emergency cesarean births.

A prospective study showed that failed operative vaginal delivery – that is, a cesarean delivery after an attempted operative vaginal delivery – occurred for 10.1% of patients with obesity and 4.2% of those without obesity.

Researchers presented the findings at the meeting sponsored by the Society for Maternal-Fetal Medicine.

NEW ORLEANS – Adults with moderate to severe chronic hand eczema who were randomized to treatment with delgocitinib cream had significantly greater improvement in efficacy outcomes at 16 weeks, compared with those who received vehicle cream, results from a pivotal phase 3 trial showed.

“Chronic hand eczema is the most frequent chronic inflammatory disorder affecting the hands,” Robert Bissonnette, MD, a dermatologist who is founder and CEO of Innovaderm Research, said at the annual meeting of the American Academy of Dermatology, where the study was presented during a late-breaking research session. “It’s associated with pain, pruritus, and has a huge impact on quality of life,” and results with current topical treatments are often unsatisfactory, he noted.

Delgocitinib is an investigational topical pan-JAK inhibitor that inhibits activation of the JAK-STAT pathway and targets key mediators of chronic hand eczema. In a phase 2b dose-ranging trial, twice-daily treatment with delgocitinib cream demonstrated significantly greater efficacy, compared with the cream vehicle, and was well tolerated in adults with mild to severe chronic hand eczema.

For the phase 3 study, known as DELTA 1, researchers randomized 487 adults with moderate to severe chronic hand eczema to receive twice-daily applications of delgocitinib cream 20 mg/g or cream vehicle for 16 weeks. After week 16, patients had the option to enter a long-term extension trial, which is currently ongoing. DELTA 1 was limited to adults with a diagnosis of chronic hand eczema defined as hand eczema that had persisted for more than 3 months or had returned more than twice within the past 12 months; an Investigator’s Global Assessment for chronic hand eczema (IGA-CHE) score of 3 (moderate) or 4 (severe); a weekly average Hand Eczema Symptom Diary (HESD) itch score of 4 or more points, and a medical history of inadequate response to topical corticosteroids within the past 12 months or for whom treatment with topical corticosteroids was not medically advisable.

The IGA-CHE scale used in the trial was new, “where, in order to be almost clear, the only sign that could be present on the skin was barely perceptible erythema,” Dr. Bissonnette said. He noted that he has used many IGA scales over the more than 25 years he has been involved with clinical trials, and “this was the first that used a scale with a bar so high.” Key secondary endpoints include a 75% and 90% improvement in Hand Eczema Severity Index (HECSI) from baseline at week 16 and a 4-point or greater improvement in the Dermatology Life Quality Index (DLQI) from baseline at week 16.

The median age of patients was 44 years, 88% were White, 4% were Asian, 1% were Black, and the remainder were from other racial groups. One-third of patients (33%) had severe hand eczema based on their IGA-CHE score, the median HECSI was 65 (in line with severe disease), and the median DLQI was 12. As for previous chronic hand eczema treatments, 19% had undergone phototherapy, 14% had tried oral retinoids, and 12% had tried oral corticosteroids.

In the study, a greater proportion of delgocitinib-treated patients achieved the primary endpoint of IGA-CHE 0/1, compared with the cream vehicle group at week 4 (15.4% vs. 4.9%; P < .001); week 8 (22.8% vs. 10.5%; P = .001), and week 16 (19.7% vs. 9.9%; P = .006). “As early as week 2, there is a separation between cream and vehicle,” Dr. Bissonnette said. When reviewing the results and the patients in the trial, he said that, in his personal opinion, “I don’t think this is uniquely representative of the efficacy of the drug,” because of the IGA scale that was used, which set such a high bar for efficacy.

As for secondary endpoints, a greater proportion of delgocitinib-treated patients than those in the vehicle group achieved a HESCI-75 (49.2% vs. 23.5%), a HECSI-90 (29.5% vs. 12.3%), and a 4-point or greater improvement on the DLQI (74.4% vs 50%; P < .001 for all endpoints).

Delgocitinib had a similar safety profile as the vehicle over 16 weeks, with no difference between the delgocitinib and vehicle arms in the proportion of patients who had adverse events (45.2% vs. 50.6%, respectively) and serious adverse events (1.8% vs. 1.9%). The most common adverse events (defined as 5% or greater in any treatment group) during the study were COVID-19 infections and nasopharyngitis; rates were comparable in the two arms.

Raj Chovatiya, MD, PhD, a dermatologist who directs the Center for Eczema and Itch at Northwestern University, Chicago, who was asked to comment on the study, said that chronic hand eczema can be functionally limiting for many patients. “Given its focal symptoms but multifaceted immunopathogenesis, topical JAK inhibition represents a rational strategy for targeted treatment,” Dr. Chovatiya told this news organization. He was not an investigator in the trial.

“In the phase 3 DELTA 1 study, topical delgocitinib cream was superior to vehicle control with nearly one out of five patients achieving clear or almost clear skin, with no difference in total adverse events between groups. While both comparative and long-term data would be helpful to better assess how delgocitinib cream stacks up against common topical anti-inflammatories and how it may be used for a chronic condition that typically requires ongoing treatment, these findings move us closer to a potential first-in-class approved therapy for chronic hand eczema.”

Dr. Bissonnette disclosed that he served as a consultant and investigator for the developer of delgocitinib, LEO Pharma, on this study. He has also received grants and research funding from many other pharmaceutical companies. Dr. Chovatiya disclosed that he is a consultant to, a speaker for, and/or a member of the advisory board for several pharmaceutical companies, including LEO Pharma.

NEW ORLEANS – For the treatment of plaque psoriasis, a novel oral phosphodiesterase-4 (PDE4) inhibitor achieved high rates of response, compared with placebo, according to results of a phase 2 clinical trial presented as a late-breaker at the annual meeting of the American Academy of Dermatology.

The phase 2b data, which are prompting a phase 3 trial, suggest that the drug, called orismilast, “is a potential new addition to the psoriasis armamentarium,” reported Lars E. French, MD, professor and chair, department of dermatology, Ludwig Maximilian University of Munich (Germany).

Ted Bowsworth/MDedge News

At the same session, findings from another study supported off-label use of oral roflumilast (Daliresp and generic), a PDE4 inhibitor approved for severe chronic obstructive pulmonary disease (COPD). The only PDE4 inhibitors with an indication for psoriasis are roflumilast, approved as a cream (Zoryve), and apremilast (Otezla), approved as an oral therapy.
 

Phase 2 study of orismilast

In the orismilast trial, Dr. French attributed the efficacy observed  to the potency of orismilast on the B and D subtypes of PDE4 associated with inflammation. One clue is that these specific subtypes are overly expressed in the skin of patients with either psoriasis or atopic dermatitis.

“When compared to apremilast, orismilast is at least two to fivefold more potent on all PDE4 isoforms and up to 39 times more potent on some of the PDE4 B and D isoforms,” said Dr. French, referring to preclinical findings in human whole blood and blood cells and in a mouse model of chronic inflammation.

The efficacy of orismilast in an immediate-release oral formulation was previously demonstrated in a recently published phase 2a trial, but the newest study tested a modified-release formulation of orismilast to test its potential to improve tolerability.

In the study, 202 adult patients with moderate to severe psoriasis (Psoriasis Area Severity Index [PASI] score ≥ 12) were randomly assigned to one of three doses of orismilast or to placebo. Each of the three doses – 20 mg, 30 mg, or 40 mg – were administered twice daily. The primary endpoint was change in PASI score at 16 weeks. Secondary endpoints included PASI 75 responses (signifying 75% clearance) and safety.

Relative to placebo, which was associated with a PASI improvement of 17%, all three of the tested orismilast doses were superior in a dose-dependent manner. The rates of response were 53%, 61%, and 64% for the 20-mg, 30-mg, and 40-mg twice-daily doses, respectively.

The PASI improvements were rapid, Dr. French said. At 4 weeks, PASI scores climbed from baseline by nearly 40% for those on all orismilast doses, which was more than double the improvement in the placebo group.

In the intention-to-treat analysis with missing data counted as nonresponders, the proportion of patients reaching PASI-75 scores at 16 weeks were 39%, 49%, 45%, and 17%, in the 20-mg, 30-mg, 40-mg, and placebo groups, respectively. The proportion of patients experiencing complete or near-complete skin clearance defined by a PASI 90 were 24%, 22%, 28%, and 8%, respectively.

The side-effect profile was consistent with other PDE4 inhibitors. The most common adverse events included gastrointestinal complaints, such as diarrhea and nausea, as well as headache and dizziness. But the majority of these events were of low grade, and they were largely confined to the first 4 weeks of treatment, which is a pattern reported with other PDE4 inhibitors in psoriasis and other chronic inflammatory diseases, such as COPD, according to Dr. French.

“There were no discontinuations for a treatment-related adverse event in the arms receiving either the 20-mg or the 30-mg doses,” Dr. French reported. There were only two serious adverse events, and neither were considered by trial investigators to be related to orismilast.

Based on the limited therapeutic gain but greater risk for adverse events on the 40-mg twice-daily dose, “the question is now whether to move forward with the 20-mg or the 30-mg dose,” said Dr. French, who said planning of a phase 3 trial is underway.
 

Phase 2 study of roflumilast

However, this was not the only set of data on an oral PDE4 inhibitor presented as a late-breaker at the AAD meeting. For clinicians looking for a more immediate and less expensive alternative to apremilast, another study indicated that off-label use of oral roflumilast is an option.

In an investigator-initiated, multicenter, double-blind, placebo-controlled trial conducted in Denmark, the rate of response to oral roflumilast at 24 weeks, including the clear or almost clear response, was on the same general order of magnitude as that seen in the orismilast study, reported Alexander Egeberg, MD, PhD, professor of dermatology, University of Copenhagen.

“At 24 weeks, 21.7% had achieved a PASI 90, and 8.7% achieved a PASI 100,” Dr. Egeberg said.

Oral roflumilast has been available for the treatment of COPD for more than 10 years and is now available in a generic formulation. This study was conducted independent of any pharmaceutical company involvement, and the high rate of response and low risk of adverse events suggests that patients can benefit from a PDE4 inhibitor in a very low-cost form.

“Generic oral roflumilast is cheaper than a Starbucks coffee,” Dr. Egeberg said.

In this trial, 46 patients were randomly assigned to placebo or to the COPD-approved roflumilast dose of 500 mcg once daily. The primary endpoint was change in PASI scores from baseline to week 12, which Dr. Egeberg pointed out is a shorter time frame than the 16 weeks more typical of psoriasis treatment studies.

At week 12, the median improvement in PASI was 34.8% in the roflumilast group versus 0% in the placebo group. Patients were then followed for an additional 12 weeks, but those randomized to placebo were switched to the active treatment. By week 24, the switch patients had largely caught up to those initiated on roflumilast for median PASI improvement (39.1% vs. 43.5%).

Similar to orismilast, roflumilast “was generally well tolerated,” Dr. Egeberg said. The adverse events were consistent with those associated with PDE4 inhibitors in previous trials, whether in psoriasis or COPD. There was only one serious adverse event, and it was not considered treatment related. Discontinuations for adverse events “were very low.”

In a population with a relatively high rate of smoking, Dr. Egeberg further reported, lung function was improved, a remark initially interpreted as a joke by some attending the presentation. However, Dr. Egeberg confirmed that lung function was monitored, and objective improvements were recorded.

By Danish law, the investigators were required to inform the manufacturers of roflumilast. Despite the results of this study, he is not aware of any plans to seek an indication for roflumilast in psoriasis, but he noted that the drug is readily available at a low price.

For those willing to offer this therapy off label, “you can start using it tomorrow if you’d like,” he said.

Dr. French reports financial relationships with Almirall, Amgen, Biotest, Galderma, Janssen Cilag, Leo Pharma, Pincell, Regeneron, UCB, and UNION Therapeutics, which provided funding for this trial. Dr. Egeberg reports financial relationships with Eli Lilly, Galderma, Janssen-Cilag, Novartis, and Pfizer.

NEW ORLEANS – For the treatment of plaque psoriasis, a novel oral phosphodiesterase-4 (PDE4) inhibitor achieved high rates of response, compared with placebo, according to results of a phase 2 clinical trial presented as a late-breaker at the annual meeting of the American Academy of Dermatology.

The phase 2b data, which are prompting a phase 3 trial, suggest that the drug, called orismilast, “is a potential new addition to the psoriasis armamentarium,” reported Lars E. French, MD, professor and chair, department of dermatology, Ludwig Maximilian University of Munich (Germany).

At the same session, findings from another study supported off-label use of oral roflumilast (Daliresp and generic), a PDE4 inhibitor approved for severe chronic obstructive pulmonary disease (COPD). The only PDE4 inhibitors with an indication for psoriasis are roflumilast, approved as a cream (Zoryve), and apremilast (Otezla), approved as an oral therapy.
 

Phase 2 study of orismilast

In the orismilast trial, Dr. French attributed the efficacy observed  to the potency of orismilast on the B and D subtypes of PDE4 associated with inflammation. One clue is that these specific subtypes are overly expressed in the skin of patients with either psoriasis or atopic dermatitis.

“When compared to apremilast, orismilast is at least two to fivefold more potent on all PDE4 isoforms and up to 39 times more potent on some of the PDE4 B and D isoforms,” said Dr. French, referring to preclinical findings in human whole blood and blood cells and in a mouse model of chronic inflammation.

The efficacy of orismilast in an immediate-release oral formulation was previously demonstrated in a recently published phase 2a trial, but the newest study tested a modified-release formulation of orismilast to test its potential to improve tolerability.

In the study, 202 adult patients with moderate to severe psoriasis (Psoriasis Area Severity Index [PASI] score ≥ 12) were randomly assigned to one of three doses of orismilast or to placebo. Each of the three doses – 20 mg, 30 mg, or 40 mg – were administered twice daily. The primary endpoint was change in PASI score at 16 weeks. Secondary endpoints included PASI 75 responses (signifying 75% clearance) and safety.

Relative to placebo, which was associated with a PASI improvement of 17%, all three of the tested orismilast doses were superior in a dose-dependent manner. The rates of response were 53%, 61%, and 64% for the 20-mg, 30-mg, and 40-mg twice-daily doses, respectively.
