Adjuvant pembrolizumab significantly improves disease-free survival (DFS) compared to placebo in patients with early-stage non–small cell lung cancer (NSCLC) who have undergone complete resection, according to findings from the phase 3 PEARLS/KEYNOTE-091 (PEARLS) study.

Patients in the pembrolizumab arm demonstrated median DFS nearly 12 months longer than those in the placebo arm (53.6 vs. 42.0 months). Investigators observed a DFS benefit for patients with any programmed death-ligand 1 (PD-L1) expression.

“We believe that pembrolizumab has the potential to become a new adjuvant treatment option for patient with [stage IB to IIIA] non–small cell lung cancer following complete resection and adjuvant chemotherapy when recommended,” concluded first author Luis Paz-Ares, MD, chair of the clinical research unit at Hospital Universitario 12 de Octubre, CNIO & Universidad Complutense, Madrid. “Pembrolizumab provided a benefit regardless of pathological stage and PD-L1 progression subgroup.”

The findings were presented by Dr. Paz-Ares at the European Society for Medical Oncology (ESMO) March virtual plenary session and published March 17 in Annals of Oncology.

Pembrolizumab is the standard treatment for patients with advanced NSCLC, but its efficacy in early-stage disease remains unclear. To determine whether patients with early-stage disease benefit from pembrolizumab, Dr. Paz-Ares and colleagues randomized 1,177 adults with stage IB, II, or IIIA NSCLC to 200 mg of pembrolizumab (n = 590) or placebo (n = 587) every 3 weeks.

All patients had Eastern Cooperative Oncology Group performance status of 0-1, and any level of PD-L1 expression. Of the study participants, 168 in the pembrolizumab arm and 165 in the placebo arm had PD-L1 expression and a tumor proportion score (TPS) of at least 50%.

Overall, patients receiving pembrolizumab had a DFS of 53.6 months compared to 42.0 months in the placebo arm (hazard ratio [HR], 0.76; P = .0014). The DFS benefit was generally consistent across patients with PD-L1 TPS <1%, 1%-49%, and ≥50%. In the subset of patients with PD-L1 TPS ≥50%, a slightly higher percentage of patients in the pembrolizumab group demonstrated DFS at 18 months (71.7% vs. 70.2%), but the difference did not reach statistical significance (HR, 0.82; P = .14).

Overall survival (OS) at 18 months was 91.7% in the treatment arm and 91.3% in the placebo arm (HR, 0.87; P = .17), but the data were immature.

“The disease-free survival benefit was observed across most prespecified subgroups,” Dr. Paz-Ares said.

No new safety concerns were raised. Grade 3 or greater adverse events occurred in 34.1% of patients in the treatment arm and 25.8% in the placebo arm. Adverse events led to discontinuation in 19.8% of patients receiving pembrolizumab and 5.9% of patients in the placebo group.

Invited discussant Martin Reck, MD, said these findings represent forward progress. “We do see many patients with distant relapse, which indicates that we have to improve our control of the systemic relapse,” said Dr. Reck, head of the department of thoracic oncology and the clinical trial department at the Lungen Clinic Grosshansdorf, Germany.

Prior data provide a rationale for using immune checkpoint inhibition in early-stage NSCLC, and both the PEARLS study and the IMpower010 trial evaluating atezolizumab in a similar setting have demonstrated relevant improvements in DFS.

“I think we are entering the times of perioperative immunotherapies. We are seeing the first signals of efficacy for adjuvant immunotherapy in two large, randomized trials,” Dr. Reck said.

Based on the PEARLS trial results, Dr. Reck said that PD-L1 appears to have predictive and prognostic value but noted that “several other clinical trials say PD-L1 expression is a poor prognostic marker” for sensitivity to immune checkpoint inhibitor. Given this potential inconsistency, Dr. Reck called for further follow-up in this patient population and for studies in larger groups of patients to further delineate the role of PD-L1 as well as EGFR mutations and adjuvant chemotherapy in patients with early NSCLC.

The PEARLS study was funded by Merck Sharp & Dohme Corp. Dr. Paz-Ares and Dr. Reck disclosed numerous relationships with pharmaceutical companies.

BOSTON – Untinted chemical sunscreens on the market are not sufficient to protect the skin from the effects of visible light, complicating sun protection efforts for patients with melasma and other conditions aggravated by sun exposure, according to Henry W. Lim, MD.

A sensible alternative for patients with melasma are tinted sunscreens with an SPF of 30 or greater, which offer both UV and blue light protection, Dr. Lim, former chair of the department of dermatology at Henry Ford Health, Detroit, said at the annual meeting of the American Academy of Dermatology. Tinted sunscreens contain iron oxides; some also contain pigmentary titanium dioxide.

“Black, red, and yellow iron oxide all reflect visible light,” he added, noting that currently, there are no regulations as to how tinted sunscreens are marketed, making it difficult for practicing clinicians to advise patients about what products to choose. However, he said, “unlike ‘SPF’ and ‘broad spectrum’ labeling, there is no specific guidance on tinted sunscreens. “ ‘Universal’ shade is a good start but might not be ideal for users with very fair or deep skin tones,” he noted.

In December 2021, a guide to tinted sunscreens, written by Dr. Lim and colleagues, was published, recommending that consumers choose a product that contains iron oxides, is labeled as broad spectrum, and has an SPF of at least 30.

A comprehensive list of 54 tinted sunscreens with an SPF of 30 or greater that contain iron oxide is also available . The authors of the guide contributed to this resource, which lists sunscreens by average price per ounce.

At the meeting, Dr. Lim highlighted tinted sunscreens that cost about $20 or less per ounce. They include Supergoop 100% Mineral CC Cream (SPF 50); Bare Republic Mineral Tinted Face Sunscreen Lotion (SPF 30); CeraVe Hydrating Sunscreen with Sheer Tint (SPF 30); Tizo Ultra Zinc Body & Face Sunscreen (SPF 40); Vichy Capital Soleil Tinted Face Mineral Sunscreen (SPF 60); EltaMD UV Elements Tinted (SPF 44); La Roche-Posay Anthelios Ultra-Light Tinted Mineral (SPF 50), SkinMedica Essential Defense Mineral Shield (SPF 32), ISDIN Eryfotona Ageless Ultralight Tinted Mineral Sunscreen (SPF 50), and SkinCeuticals Physical Fusion UV Defense (SPF 50).
 

Sunscreens with antioxidants

Sunscreens with biologically active antioxidants may be another option for patients with melasma. A proof-of-concept study that Dr. Lim and colleagues conducted in 20 patients found that application of a blend of topical antioxidants (2%) was associated with less erythema at the application sites among those with skin phototypes I-III and less pigmentation at the application sites among those with skin phototypes IV-VI after exposure to visible light and UVA-1, compared with controls.

Certain antioxidants have been added to sunscreens currently on the market, including niacinamide (vitamin B₃), licochalcone A, carotenoids (beta-carotene), vitamin E, vitamin C, glycyrrhetinic acid, and diethylhexyl syringylidenemalonate.

A recently published paper on the role of antioxidants and free radical quenchers in protecting skin from visible light referred to unpublished data from Dr. Lim (the first author) and colleagues, which demonstrated a significant reduction in visual light–induced hyperpigmentation on skin with sunscreen that contained the antioxidants vitamin E, vitamin C, diethylhexyl syringylidenemalonate, licochalcone A, and a glycyrrhetinic acid, compared with sunscreen that had no antioxidants.
 

Novel filters

Another emerging option is sunscreen with new filters that cover UVA-1 and visible light. In a randomized, controlled trial of 19 patients, researchers evaluated the addition of methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate (MCE) absorber, a new UVA-1 filter known as Mexoryl 400, which has a peak absorption of 385 nm, to a sunscreen formulation.

“Currently, peak absorption in the U.S. is with avobenzone, which peaks at about 357 nm,” but MCE “covers a longer spectrum of UVA-1,” Dr. Lim said. The researchers found that the addition of MCE reduced UVA-1-induced dermal and epidermal alterations at cellular, biochemical, and molecular levels; and decreased UVA-1-induced pigmentation.

Another relatively new filter, phenylene bis-diphenyltriazine (also known as TriAsorB) not only protects against UVA but it extends into the blue light portion of visible light, according to a recently published paper. According to a press release from Pierre Fabre, which has developed the filter, studies have shown that TriAsorB is not toxic for three key species of marine biodiversity: a coral species, a phytoplankton species, and a zooplankton.

This filter and MCE are available in Europe but not in the United States.

Dr. Lim reported that he is an investigator for Incyte, L’Oréal, Pfizer, and the Patient-Centered Outcomes Research Institute.

WASHINGTON – Patients with heart failure who received an annual influenza vaccine for 3 years running had significantly fewer all-cause hospitalizations and significantly fewer cases of pneumonia during that time, compared with placebo-treated patients with heart failure, in a prospective, randomized, global trial with 5,129 participants.

Although the results failed to show a significant reduction in all-cause deaths linked to influenza vaccination, compared with controls during the entire 3 years of the study, the results did show a significant 21% relative mortality-risk reduction by vaccination during periods of peak influenza circulation, and a significant 23% reduction in cardiovascular deaths, compared with controls during peak seasons.

“This is the first randomized, controlled trial of influenza vaccine in patients with heart failure, and we showed that vaccination reduces deaths” during peak influenza seasons, Mark Loeb, MD, said during a press briefing at the annual scientific sessions of the American College of Cardiology. The results send “an important global message that patients with heart failure should receive the influenza vaccine,” said Dr. Loeb, a professor at McMaster University, Hamilton, Ont., who specializes in clinical epidemiology and infectious diseases.

Dr. Loeb admitted that he and his associates erred when they picked the time window to assess the two primary endpoints for the trial: the combined rate of cardiovascular death, nonfatal MI, and nonfatal stroke, and this combined endpoint plus hospitalizations for heart failure.

The time window they selected was the entirety of all 3 years following three annual immunizations. That was a mistake.
 

No flu vaccine benefit outside flu season

“We know that the influenza vaccine will not have any effect outside of when influenza is circulating. In retrospect, we should have done that,” Dr. Loeb bemoaned during his talk. He chalked up the bad choice to concern over collecting enough endpoints to see a significant between-group difference when the researchers designed the study.

For the entire 3 years of follow-up, influenza vaccination was tied to a nonsignificant 7% relative risk reduction for the first primary endpoint, and a nonsignificant 9% relative risk reduction for the second primary endpoint, he reported.

But Dr. Loeb lobbied for the relevance of several significant secondary endpoints that collectively showed a compelling pattern of benefit during his talk. These included, for the full 3-years of follow-up, important, significant reductions relative to placebo of 16% for first all-cause hospitalizations (P = .01), and a 42% relative risk reduction in first cases of pneumonia (P = .0006).

Then there were the benefits that appeared during influenza season. In that analysis, first events for the first primary endpoint fell after vaccination by a significant 18% relative to placebo. The in-season analysis also showed the significant cuts in both all-cause and cardiovascular deaths.

Despite the neutral primary endpoints, “if you look at these data as a whole I think they speak to the importance of vaccinating patients with heart failure against influenza,” Dr. Loeb maintained.



‘Totality of evidence supports vaccination’

“I agree that the totality of evidence supports influenza vaccination,” commented Mark H. Drazner, MD, professor and clinical chief of cardiology at the University of Texas Southwestern Medical Center, Dallas, who was designated discussant for the report.

“The message should be to offer influenza vaccine to patients with heart failure,” Dr. Drazner said in an interview. “Previous data on influenza vaccine in patients with heart failure were largely observational. This was a randomized, prospective, placebo-controlled trial. That’s a step forward. Proving efficacy in a randomized trial is important.”

Dr Drazner added that his institution already promotes a “strong mandate” to vaccinate patients with heart failure against influenza.

“The influenza vaccine is a very effective and cost-efficient public health measure. Preventing hospitalizations of patients with heart failure has so many benefits,” commented Craig Beavers, PharmD, vice president of professional services at Baptist Health in Paducah, Ky., and a discussant during the press briefing.

The Influenza Vaccine To Prevent Adverse Vascular Events (IVVE) trial enrolled people with heart failure in New York Heart Association functional class II, III, or IV from any of 10 low- and middle-income countries including China, India, the Philippines, and multiple countries from Africa and the Middle East. They averaged 57 years of age, and slightly more than half were women.

IVVE was sponsored by McMaster University; the only commercial support that IVVE received was a free supply of influenza vaccine from Sanofi Pasteur. Dr. Loeb, Dr. Drazner, and Dr. Beavers had no disclosures.

Despite the neutral primary endpoints, “if you look at these data as a whole I think they speak to the importance of vaccinating patients with heart failure against influenza,” Dr. Loeb maintained.



‘Totality of evidence supports vaccination’

“I agree that the totality of evidence supports influenza vaccination,” commented Mark H. Drazner, MD, professor and clinical chief of cardiology at the University of Texas Southwestern Medical Center, Dallas, who was designated discussant for the report.

“The message should be to offer influenza vaccine to patients with heart failure,” Dr. Drazner said in an interview. “Previous data on influenza vaccine in patients with heart failure were largely observational. This was a randomized, prospective, placebo-controlled trial. That’s a step forward. Proving efficacy in a randomized trial is important.”

Dr Drazner added that his institution already promotes a “strong mandate” to vaccinate patients with heart failure against influenza.

“The influenza vaccine is a very effective and cost-efficient public health measure. Preventing hospitalizations of patients with heart failure has so many benefits,” commented Craig Beavers, PharmD, vice president of professional services at Baptist Health in Paducah, Ky., and a discussant during the press briefing.

The Influenza Vaccine To Prevent Adverse Vascular Events (IVVE) trial enrolled people with heart failure in New York Heart Association functional class II, III, or IV from any of 10 low- and middle-income countries including China, India, the Philippines, and multiple countries from Africa and the Middle East. They averaged 57 years of age, and slightly more than half were women.

IVVE was sponsored by McMaster University; the only commercial support that IVVE received was a free supply of influenza vaccine from Sanofi Pasteur. Dr. Loeb, Dr. Drazner, and Dr. Beavers had no disclosures.

WASHINGTON – Patients with heart failure who received an annual influenza vaccine for 3 years running had significantly fewer all-cause hospitalizations and significantly fewer cases of pneumonia during that time, compared with placebo-treated patients with heart failure, in a prospective, randomized, global trial with 5,129 participants.

Although the results failed to show a significant reduction in all-cause deaths linked to influenza vaccination, compared with controls during the entire 3 years of the study, the results did show a significant 21% relative mortality-risk reduction by vaccination during periods of peak influenza circulation, and a significant 23% reduction in cardiovascular deaths, compared with controls during peak seasons.

“This is the first randomized, controlled trial of influenza vaccine in patients with heart failure, and we showed that vaccination reduces deaths” during peak influenza seasons, Mark Loeb, MD, said during a press briefing at the annual scientific sessions of the American College of Cardiology. The results send “an important global message that patients with heart failure should receive the influenza vaccine,” said Dr. Loeb, a professor at McMaster University, Hamilton, Ont., who specializes in clinical epidemiology and infectious diseases.

Dr. Loeb admitted that he and his associates erred when they picked the time window to assess the two primary endpoints for the trial: the combined rate of cardiovascular death, nonfatal MI, and nonfatal stroke, and this combined endpoint plus hospitalizations for heart failure.

The time window they selected was the entirety of all 3 years following three annual immunizations. That was a mistake.
 

No flu vaccine benefit outside flu season

“We know that the influenza vaccine will not have any effect outside of when influenza is circulating. In retrospect, we should have done that,” Dr. Loeb bemoaned during his talk. He chalked up the bad choice to concern over collecting enough endpoints to see a significant between-group difference when the researchers designed the study.

For the entire 3 years of follow-up, influenza vaccination was tied to a nonsignificant 7% relative risk reduction for the first primary endpoint, and a nonsignificant 9% relative risk reduction for the second primary endpoint, he reported.

But Dr. Loeb lobbied for the relevance of several significant secondary endpoints that collectively showed a compelling pattern of benefit during his talk. These included, for the full 3-years of follow-up, important, significant reductions relative to placebo of 16% for first all-cause hospitalizations (P = .01), and a 42% relative risk reduction in first cases of pneumonia (P = .0006).

Then there were the benefits that appeared during influenza season. In that analysis, first events for the first primary endpoint fell after vaccination by a significant 18% relative to placebo. The in-season analysis also showed the significant cuts in both all-cause and cardiovascular deaths.

Just about every patient-reported outcome favors adding immunotherapy to standard chemotherapy for patients with metastatic non-small cell lung cancer, according to an analysis presented at the annual European Lung Cancer Congress (ELCC) on March 30.

“Overall, it is very clear that chemotherapy plus immunotherapy prolongs the time to symptom deterioration and actually improves symptoms” in this patient population, said study discussant Luis Paz-Ares, MD, PhD, chair of medical oncology at the Hospital Universitario 12 de Octubre, Madrid, who was not involved in the research.

Last September, investigators reported efficacy outcomes from the phase 3 POSEIDON trial, which randomized 1,013 patients with EGFR/ALK wild-type mNSCLC to one of three first-line options: chemotherapy alone, chemotherapy plus the checkpoint inhibitor durvalumab, or chemotherapy plus two check-point inhibitors, durvalumab and tremelimumab. The analysis showed improved progression-free survival in both immunotherapy arms as well as a significant 2.3-month overall survival advantage with dual immunotherapy and a nonsignificant 1.6-month advantage with single agent durvalumab.

At the ELCC meeting, study presenter and lead investigator Edward Garon, MD, reported the latest data on the trial’s secondary endpoints: patient-reported outcomes. Global health status, functioning, and symptom scores were assessed using two questionnaires, the EORTC QLQ-C30 and EORTC QLQ-LC13.

Overall, Dr. Garon and colleagues reported a longer time to deterioration in all three areas – global health status, functioning, and symptoms – for patients who received immunotherapy versus chemotherapy alone, with similar results in both immunotherapy arms.

Time to deterioration in global health status, for instance, was a median of about 8 months on both immunotherapy regimens versus 5.6 months with chemotherapy alone. The positive findings held for many patient-reported treatment side effects, including dyspnea, hemoptysis, nausea/vomiting, and insomnia, but the benefits of adding immunotherapy weren’t always statistically significant.

Adding one or both checkpoint inhibitors to chemotherapy “improved efficacy while delaying deterioration in symptoms, functioning, and [health-related quality of life] versus chemotherapy alone in patients with mNSCLC,” concluded Dr. Garon, a thoracic medical oncologist at the University of California, Los Angeles. Plus, he added, “the pattern was observed across nearly all prespecified symptoms and domains of interest.”

According to study discussant Dr. Paz-Ares, “the data seem to be very consistent with all the trials asking similar questions.” The important thing here is figuring out the ideal candidates for dual inhibitor therapy, he said.

With positive efficacy and patient-reported outcomes for single and dual immunotherapy in this trial, it’s a “relatively straightforward” decision to add immunotherapy to chemotherapy for patients with mNSCLC, Massimo Di Maio, a medical oncologist at the University of Turin, Italy, said in an editorial on the ELCC’s news site.

However, that’s not always the case for every cancer type, which makes patient-reported outcomes “crucial” for determining the right treatment for each patient. Some might opt for a modest survival benefit regardless of the side effects, while others might favor a less toxic approach, even it means not living quite as long, he said.

The problem, he stressed, is that trials often release efficacy data well before patient-reported outcomes, which makes weighing the benefits and risks of a treat-ment option more difficult. The delay between efficacy and patient-reported outcome data was about 6 months in the POSEIDON trial.

“Timing is key when it comes to using [patient reported outcomes] for decision-making in oncology,” Dr. Di Maio said. “In fact, to enable a full assessment of a treatment, results should be published concurrently with the efficacy and safety data. Unfortunately, this is generally not the case.”

POSEIDON was funded by AstraZeneca, which markets durvalumab and is developing tremelimumab. Dr. Garon reported grants from the company. Dr. Paz-Ares reported honoraria and institutional research grants from AstraZeneca. Dr. Di Maio is a consultant for AstraZeneca and reported receiving honoraria and personal fees from the company.

Early results from a small trial of an investigative drug suggests it is safe and may improve executive function in patients with mild cognitive impairment (MCI) and mild dementia associated with Alzheimer’s disease. Patients performed better in cognitive testing after just 2 weeks, especially in areas of executive functioning. Clinicians involved in the study also reported improvements in patients’ ability to complete daily activities, especially in complex tasks such as using a computer, carrying out household chores, and managing their medications.

“It’s pretty incredible to see improvement over the course of a week to a week and a half,” said study investigator Aaron Koenig, MD, vice president of Early Clinical Development at Sage Therapeutics in Cambridge, Mass. “Not only are we seeing objective improvement, we’re also seeing a subjective benefit.”

The drug, SAGE-718, is also under study for MCI in patients with Huntington’s disease, the drug’s primary indication, and Parkinson’s disease.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

Improved executive function

SAGE-718 is in a new class of drugs called positive allosteric modulator of N-methyl-D-aspartate (NMDA) receptors, which are thought to improve neuroplasticity.

For the phase 2a open-label LUMINARY trial, researchers enrolled 26 patients ages 50-80 years with Alzheimer’s disease who had MCI. Patients completed a battery of cognitive tests at the study outset, again at the end of treatment, and again after 28 days.

Participants received SAGE-718 daily for 2 weeks and were followed for another 2 weeks.

The study’s primary outcome was safety. Seven patients (26.9%) reported mild or moderate treatment-emergent adverse events (AEs), and there were no serious AEs or deaths.

However, after 14 days, researchers also noted improvements from baseline on multiple tests of executive functioning, learning, and memory. And at 28 days, participants demonstrated significantly better Montreal Cognitive Assessment scores, compared with baseline (+2.3 points; P < .05), suggesting improvement in global cognition.

“We know that in Alzheimer’s and other neurodegenerative conditions there is a change in cognition, the ability to think, the ability to do things,” Dr. Koenig said. “What we’ve seen with SAGE-718 to date, all the way back to our phase 1 studies, is a cognitively beneficial effect, but more specifically an improvement in executive functioning.”
 

Intentional small study design

Commenting on the findings, Percy Griffin, PhD, MSc, director of scientific engagement for the Alzheimer’s Association, said that because of the small study size, short follow-up, and limited data available in the conference abstract, “we cannot speculate about the efficacy of this investigational therapy.”

“Bigger picture, the real-world clinical meaningfulness of research results that are generated in highly controlled circumstances is an important question that is being discussed right now throughout the Alzheimer’s field,” he added.

However, Dr. Koenig countered that the small study design was intentional. “Over the course of a year, we can get to the answer in different patient populations rather than running these rather large and arduous trials that may pan out to not be positive,” he said.

“The purpose here is to say, directionally, are we seeing improvement that warrants further investigation? If you don’t see an effect in a small number of patients, if you don’t see that effect rather quickly, and if you don’t see an effect that should translate into something meaningful, we at SAGE believe that you may not have a drug there,” he added.

Sage Therapeutics plans to launch a phase 2b placebo-controlled trial later this year to study SAGE-718 in more Alzheimer’s patients over a longer period of time.

The study was funded by SAGE Therapeutics. Dr. Koenig is an employee of SAGE and reports no other conflicts. Dr. Griffin has disclosed no relevant financial relationships.

An investigational drug that blocks the dopamine-1 (D1) receptor reduces tics and is safe and well tolerated in children with Tourette syndrome, a new study shows.

Importantly, unlike current medications for the disorder, ecocipam does not lead to weight gain, anxiety, depression, or tardive dyskinesia, compared with placebo – a factor that may lead to better adherence.

For clinicians treating children with Tourette syndrome, the results suggest “help is on the way,” said study investigator Donald Gilbert, MD, professor of pediatrics and neurology, University of Cincinnati Children’s Hospital Medical Center.

“There may be a drug available with a new mechanism of action that is effective to suppress tics without causing weight gain or unwanted neuropsychiatric side effects,” Dr. Gilbert said.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

First-in-class agent

Tourette syndrome is a neurologic condition that causes sudden repetitive involuntary muscle movements and sounds known as tics. These movements typically develop in childhood and worsen during adolescence.

“There’s a risk of injury, such as to the neck, with tics in childhood, so it’s good to have something that makes tics less severe and less socially impairing in junior high,” said Dr. Gilbert.

While tics generally diminish by adulthood, “about 10% of the patients we see as kids persist into adulthood enough to need medical interventions,” said Dr. Gilbert.

Ecopipam is a first-in-class selective D1 receptor antagonist in clinical development for pediatric patients with Tourette syndrome. The compound was previously tested without success in schizophrenia and in obesity, the idea being that because dopamine is linked to pleasure or reward, blocking it might result in weight loss, said Dr. Gilbert.

However, earlier studies in Tourette syndrome suggested that ecopipam reduces tics in children and adults and had low metabolic and movement-related adverse effects.

Drugs currently used to treat tics include haloperidol, pimocide, and aripiprazole. All of these agents block the dopamine-2 (D2) receptor and can cause weight gain and tardive dyskinesia, said Dr. Gilbert.
 

Placebo-controlled trial

The new study included 149 patients with Tourette syndrome who had a score of at least 20 on the Yale Global Tic Severity Total Tic Score (YGTSS-TTS). The scale measures five aspects of motor and vocal tics: the number, frequency, intensity, complexity, and interference.

With that scale, intensity assesses whether tics cause injury, complexity evaluates the number of muscle group, and interference assesses whether tics interrupt functions, such as speaking or walking.

For each of the five areas, scores range from 0-5, with higher scores indicating greater severity. The motor and vocal parts have a maximum of 25 points each, for a maximum total of 50.

Participants were randomly assigned to receive once-daily oral ecopipam or placebo. A 4-week titration period was followed by an 8-week maintenance period and then a 1-week tapering period.

The primary endpoint was mean change from baseline to week 12 in scores on the YGTSS-TTS.

Results on the YGTSS-TTS showed a significant improvement in the ecopipam group, compared with placebo groups (least square [LS] mean difference: -3.44; 95% confidence interval: -6.09 to -0.79; P = .011).

The analysis indicated a 30% reduction, with an effect size of 0.48, which is “pretty good,” said Dr. Gilbert. “The amount of change is comparable to other drugs that are marketed” to treat tics.

The drug was effective for younger as well as older children. Among those aged 6-11 years, the LS mean difference was -4.95 (95% CI: -9.99 to 0.10; P = .054), and for those aged 12 to 17 years, the LS mean difference was -3.37 (95% CI: -6.51 to -0.24; P = .035).

A key secondary endpoint was the score on the Clinical Global Impression of Tourette Syndrome Severity, which Dr. Gilbert said is a more subjective measure of whether a patient’s life has improved. Here, the mean change at week 12 was significant (P = .001) for the treated group (improvement of 0.91 points), compared with the placebo group (improvement of 0.5 points).

Researchers also assessed safety and tolerability. Treatment-related adverse events (AEs) occurred in 34% of patients taking ecopipam and in 21% of those taking placebo. The most common AEs were headache (9.2%), fatigue (6.6%), somnolence (6.6%), and restlessness (5.3%).

There were no metabolic or movement-related AEs or treatment-related serious AEs.

“This drug doesn’t cause weight gain at all,” said Dr. Gilbert. He noted that there was also no difference in the groups in terms of rates of depression, anxiety, or tardive dyskinesia.
 

Significant tic reduction

Commenting on the findings, Jessica Frey, MD, a movement disorders fellow at the University of Florida, said the new double-blind, placebo-controlled study “is promising” in that it demonstrates significant tic reduction, compared with placebo without significant side effects.

“Ecopipam could potentially expand pharmacologic treatment options for children and adolescents with Tourette syndrome in the near future,” she said.

Dr. Frey will also be presenting results at the meeting of a study showing a significant correlation between tic severity and social media use among adolescents with Tourette syndrome during the COVID pandemic.

She noted that dopamine is an important neurotransmitter in the underlying pathophysiology of Tourette syndrome. In addition, although D2 receptor blockade can provide significant tic reduction, the “intolerable” side effects often linked to medications with this mechanism “can lead to discontinuation,” said Dr. Frey.

She also noted that ecopipam has previously been evaluated in an open-label study and a follow-up placebo-controlled study that demonstrated safety as well as significant tic reduction.

The study was supported by Emalex Biosciences. Dr. Gilbert and Dr. Frey report no relevant financial relationships.

An investigational drug that blocks the dopamine-1 (D1) receptor reduces tics and is safe and well tolerated in children with Tourette syndrome, a new study shows.

Importantly, unlike current medications for the disorder, ecocipam does not lead to weight gain, anxiety, depression, or tardive dyskinesia, compared with placebo – a factor that may lead to better adherence.

For clinicians treating children with Tourette syndrome, the results suggest “help is on the way,” said study investigator Donald Gilbert, MD, professor of pediatrics and neurology, University of Cincinnati Children’s Hospital Medical Center.

“There may be a drug available with a new mechanism of action that is effective to suppress tics without causing weight gain or unwanted neuropsychiatric side effects,” Dr. Gilbert said.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

First-in-class agent

Tourette syndrome is a neurologic condition that causes sudden repetitive involuntary muscle movements and sounds known as tics. These movements typically develop in childhood and worsen during adolescence.

“There’s a risk of injury, such as to the neck, with tics in childhood, so it’s good to have something that makes tics less severe and less socially impairing in junior high,” said Dr. Gilbert.

While tics generally diminish by adulthood, “about 10% of the patients we see as kids persist into adulthood enough to need medical interventions,” said Dr. Gilbert.

Ecopipam is a first-in-class selective D1 receptor antagonist in clinical development for pediatric patients with Tourette syndrome. The compound was previously tested without success in schizophrenia and in obesity, the idea being that because dopamine is linked to pleasure or reward, blocking it might result in weight loss, said Dr. Gilbert.

However, earlier studies in Tourette syndrome suggested that ecopipam reduces tics in children and adults and had low metabolic and movement-related adverse effects.

Drugs currently used to treat tics include haloperidol, pimocide, and aripiprazole. All of these agents block the dopamine-2 (D2) receptor and can cause weight gain and tardive dyskinesia, said Dr. Gilbert.
 

Placebo-controlled trial

The new study included 149 patients with Tourette syndrome who had a score of at least 20 on the Yale Global Tic Severity Total Tic Score (YGTSS-TTS). The scale measures five aspects of motor and vocal tics: the number, frequency, intensity, complexity, and interference.

With that scale, intensity assesses whether tics cause injury, complexity evaluates the number of muscle group, and interference assesses whether tics interrupt functions, such as speaking or walking.

For each of the five areas, scores range from 0-5, with higher scores indicating greater severity. The motor and vocal parts have a maximum of 25 points each, for a maximum total of 50.

Participants were randomly assigned to receive once-daily oral ecopipam or placebo. A 4-week titration period was followed by an 8-week maintenance period and then a 1-week tapering period.

The primary endpoint was mean change from baseline to week 12 in scores on the YGTSS-TTS.

Results on the YGTSS-TTS showed a significant improvement in the ecopipam group, compared with placebo groups (least square [LS] mean difference: -3.44; 95% confidence interval: -6.09 to -0.79; P = .011).

The analysis indicated a 30% reduction, with an effect size of 0.48, which is “pretty good,” said Dr. Gilbert. “The amount of change is comparable to other drugs that are marketed” to treat tics.

The drug was effective for younger as well as older children. Among those aged 6-11 years, the LS mean difference was -4.95 (95% CI: -9.99 to 0.10; P = .054), and for those aged 12 to 17 years, the LS mean difference was -3.37 (95% CI: -6.51 to -0.24; P = .035).

A key secondary endpoint was the score on the Clinical Global Impression of Tourette Syndrome Severity, which Dr. Gilbert said is a more subjective measure of whether a patient’s life has improved. Here, the mean change at week 12 was significant (P = .001) for the treated group (improvement of 0.91 points), compared with the placebo group (improvement of 0.5 points).

Researchers also assessed safety and tolerability. Treatment-related adverse events (AEs) occurred in 34% of patients taking ecopipam and in 21% of those taking placebo. The most common AEs were headache (9.2%), fatigue (6.6%), somnolence (6.6%), and restlessness (5.3%).

There were no metabolic or movement-related AEs or treatment-related serious AEs.

“This drug doesn’t cause weight gain at all,” said Dr. Gilbert. He noted that there was also no difference in the groups in terms of rates of depression, anxiety, or tardive dyskinesia.

In patients undergoing transcatheter aortic valve replacement (TAVR), the incidence of leaflet thrombosis was numerically lower in those treated with the anticoagulant edoxaban for 6 months after the procedure than in those who received dual antiplatelet therapy, although the difference was not statistically significant, in the ADAPT-TAVR study.

There was no difference in new cerebral thromboembolism or neurologic/neurocognitive function between the two groups in the study.

Also, there was no significant relation between subclinical leaflet thrombosis and increased risk for cerebral thromboembolism and neurologic dysfunction.

The ADAPT-TAVR trial was presented April 4 at the American College of Cardiology (ACC) 2022 Scientific Session by Duk-Woo Park, MD, Asan Medical Center, Seoul, South Korea. It was simultaneously published online in Circulation.

When the PCSK9 inhibitor alirocumab is added to high-intensity statins soon after an acute myocardial infarction (AMI), the reduction in atheroma volume is doubled at 12 months, compared with placebo, while other key signs of plaque stabilization, such as fibrous cap thickness, are also significantly and substantially improved, according to the results of the PACMAN-AMI trial.

The study is consistent with other PCSK9 inhibitor trials, supporting the concept that “we should be seeking very low levels of LDL-C in high-risk patients,” reported Lorenz Räber, MD, PhD, of Bern (Switz.) University Hospital, at the annual scientific sessions of the American College of Cardiology.

Primary outcome was atheroma volume

The primary endpoint was atheroma volume as determined by intravenous ultrasound (IVUS), but the secondary endpoints of maximum lipid core burden, as determined by near infrared spectroscopy (NIRS), and fibrous cap thickness, as determined by optical coherence tomography (OCT), were also adequately powered, according to Dr. Räber.

The imaging measures taken at baseline were repeated in exactly the same spot after 52 weeks on treatment.

For the primary outcome of atheroma volume, the mean 2.1% reduction among those randomized to alirocumab was more than double the 0.9% reduction in the placebo group (P = .001).

The mean reduction in lipid core volume based on a maximum lipid core burden index was also more than doubled (-79.42 vs. -37.60 maxLCBI­4mm; P = .006). The increase in fibrous cap thickness was not quite twofold greater but very close (62.67 vs. 33.19 mcm; P = .001).

From baseline, the relative reductions in LDL-C, which were reached about 4 weeks after starting treatment and maintained over the course of the study, were greater in the group randomized to alirocumab (-84.8% vs. -50.7%). This was expected, but the more important finding was a near linear relationship between reductions of LDL-C and each of these endpoints regardless of treatment, fully explaining the advantage of alirocumab, according to Dr. Räber.

For the addition of alirocumab, “these findings indicate incremental coronary plaque regression, lipid core reduction, and plaque stabilization, and provide a mechanistic rationale in favor of early initiation of very intensive LDL-C lower in the setting of an acute MI,” he said.

The results of the PACMAN-AMI trial were published simultaneously at the time of the ACC presentation.
 

Results consistent with earlier trials

Alirocumab was well tolerated. Injection site reactions (6.1% vs. 3.3%) and general allergic reactions (3.4% vs. 0%) were more common on alirocumab, but there were no significant differences between the arms of this study for serious adverse events. There were slightly more neurocognitive events (2.0 vs. 0%) and abnormal alanine transferase levels (0.7% vs. 0%) in the alirocumab group.

The data are generally consistent with two previously published trials with another PCSK9 inhibitor, according to Dr. Räber. In the randomized GLAGOV trial published more than 5 years ago, evolocumab also produced about a 1% absolute reduction (P < .001) in plaque volume at the end of 78 weeks of follow-up relative to placebo.

However, that trial was limited to patients with coronary artery disease without a recent cardiovascular event. The more recent HUYGENS trial, which was presented virtually at the 2021 annual meeting of the European Society of Cardiology meeting and has not yet been published, looked at one of the endpoints also evaluated in PACMAN-AMI. In that study of 161 randomized NSTEMI patients, there was also about a doubling of fibrous cap thickness (42.7 vs. 21.5 mcm) for the PCSK9 inhibitor relative to placebo.

Clinical endpoints were not compared in either the PACMAN-AMI or HUYGENS trial.
 

PACMAN-AMI confirms plaque stabilization

Nevertheless, the message of plaque stabilization is important, according to Anthony N. DeMaria, MD, Founding Director of the Sulpizio Cardiovascular Center at the University of San Diego. Although he acknowledged that a 1% absolute reduction in mean plaque volume might “make you want to yawn,” he argued that this is a misreading of important changes observed in plaque physiology.

“What we have now is evidence that very low lipid levels result in plaque remodeling. The plaques might not get a whole lot smaller, but the changes are important,” he said, noting, for example, that a thicker fibrous cap and increased plaque stability “clearly plays a role in reducing risk of subsequent events.”

“You cannot help but be impressed by the relationship of lipid lowering and the favorable effect on remodeling,” he added.

The data associating PCSK9 inhibitors with protection from cardiovascular events is already extensive, according to Michael J. Blaha, MD, Director of Clinical Research for Ciccarone Center for Prevention of Cardiovascular Disease, Johns Hopkins University, Baltimore, but he called PACMAN-ACS “an extremely relevant study.”

Patients with persistent cognitive impairment months after illness with mild COVID-19 have higher levels of inflammatory markers in their cerebrospinal fluid (CSF). Researchers found elevated levels of CSF immune activation and immunovascular markers in individuals with cognitive postacute sequelae of SARS-CoV-2 infection (PASC). Patients whose cognitive symptoms developed during the acute phase of COVID-19 had the highest levels of brain inflammation.

The findings add to a growing body of evidence that suggests the condition often referred to as “brain fog” has a neurologic basis, said lead author Joanna Hellmuth, MD, MHS, assistant professor of neurology at the University of California, San Francisco Weill Institute of Neurosciences and the UCSF Memory and Aging Center.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

Inflammatory response

There are no effective diagnostic tests or treatments for cognitive PASC, which prompted the investigators to study inflammation in patients with the condition. Initial findings were reported earlier in 2022, which showed abnormalities in the CSF in 77% of patients with cognitive impairment. Patients without cognitive impairments had normal CSF.

Extending that work in this new study, researchers studied patients from the Long-term Impact of Infection With Novel Coronavirus (LIINC) study with confirmed SARS-CoV-2 infection who were not hospitalized. They conducted 2-hour neurocognitive interviews and identified 23 people with new, persistent cognitive symptoms (cognitive PASC) and 10 with no cognitive symptoms who served as controls.

All participants underwent additional neurologic examination and neuropsychological testing, and half agreed to a lumbar puncture to allow researchers to collect CSF samples. The CSF was collected a median of 10.2 months after initial COVID symptoms began.

Participants with cognitive PASC had higher median levels of CSF acute phase reactants C-reactive protein (0.007 mg/L vs. 0.000 mg/L; P =.004) and serum amyloid A (0.001 mg/L vs. 0.000 mg/L; P = .001), compared with COVID controls.

The PASC group also had elevated levels of CSF immune activation markers interferon gamma–inducible protein (IP-10), interleukin-8, and immunovascular markers vascular endothelial growth factor-C and VEGFR-1, although the differences with the control group were not statistically significant.

The timing of the onset of cognitive problems was also associated with higher levels of immune activation and immunovascular markers. Patients with brain fog that developed during the acute phase of COVID-19 had higher levels of CSF VEGF-C, compared with patients whose cognitive symptoms developed more than a month after initial COVID symptoms (173 pg/mL vs. 99 pg/mL; P = .048) and COVID controls (79 pg/mL; P = .048).

Acute onset cognitive PASC participants had higher CSF levels of IP-10 (P = .030), IL-8 (P = .048), placental growth factor (P = .030) and intercellular adhesion molecule-1 (P = .045), compared with COVID controls.

Researchers believe these new findings could mean that intrathecal immune activation and endothelial activation/dysfunction may contribute to cognitive PASC and that the mechanisms involved may be different in patients with acute cognitive PASC versus those with delayed onset.

“Our data suggests that perhaps in these people with more acute cognitive changes they don’t have the return to homeostasis,” Dr. Hellmuth said, while patients with delayed onset cognitive PASC had levels more in line with COVID patients who had no cognitive issues.
 

Moving the needle forward

Commenting on the findings, William Schaffner, MD, professor of infectious diseases, Vanderbilt University Medical Center, Nashville, Tenn., said that, while the study doesn’t rule out a possible psychological basis for cognitive PASC, it adds more weight to the biological argument.

“When you have nonspecific symptoms for which specific tests are unavailable,” Dr. Schaffner explained, “there is a natural question that always comes up: Is this principally a biologically induced phenomenon or psychological? This moves the needle substantially in the direction of a biological phenomenon.”

Another important element to the study, Dr. Schaffner said, is that the patients involved had mild COVID.

“Not every patient with long COVID symptoms had been hospitalized with severe disease,” he said. “There are inflammatory phenomenon in various organ systems such that even if the inflammatory response in the lung was not severe enough to get you into the hospital, there were inflammatory responses in other organ systems that could persist once the acute infection resolved.”

Although the small size of the study is a limitation, Dr. Schaffner said that shouldn’t minimize the importance of these findings.

“That it’s small doesn’t diminish its value,” he said. “The next step forward might be to try to associate the markers more specifically with COVID. The more precise we can be, the more convincing the story will become.”

The study was funded by the National Institutes of Health. Dr. Hellmuth received grant support from the National Institutes of Health/National Institute of Mental Health supporting this work and personal fees for medical-legal consultation outside of the submitted work. Dr. Schaffner disclosed no relevant financial relationships.

Patients with persistent cognitive impairment months after illness with mild COVID-19 have higher levels of inflammatory markers in their cerebrospinal fluid (CSF). Researchers found elevated levels of CSF immune activation and immunovascular markers in individuals with cognitive postacute sequelae of SARS-CoV-2 infection (PASC). Patients whose cognitive symptoms developed during the acute phase of COVID-19 had the highest levels of brain inflammation.

The findings add to a growing body of evidence that suggests the condition often referred to as “brain fog” has a neurologic basis, said lead author Joanna Hellmuth, MD, MHS, assistant professor of neurology at the University of California, San Francisco Weill Institute of Neurosciences and the UCSF Memory and Aging Center.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

Inflammatory response

There are no effective diagnostic tests or treatments for cognitive PASC, which prompted the investigators to study inflammation in patients with the condition. Initial findings were reported earlier in 2022, which showed abnormalities in the CSF in 77% of patients with cognitive impairment. Patients without cognitive impairments had normal CSF.

Extending that work in this new study, researchers studied patients from the Long-term Impact of Infection With Novel Coronavirus (LIINC) study with confirmed SARS-CoV-2 infection who were not hospitalized. They conducted 2-hour neurocognitive interviews and identified 23 people with new, persistent cognitive symptoms (cognitive PASC) and 10 with no cognitive symptoms who served as controls.

All participants underwent additional neurologic examination and neuropsychological testing, and half agreed to a lumbar puncture to allow researchers to collect CSF samples. The CSF was collected a median of 10.2 months after initial COVID symptoms began.

Participants with cognitive PASC had higher median levels of CSF acute phase reactants C-reactive protein (0.007 mg/L vs. 0.000 mg/L; P =.004) and serum amyloid A (0.001 mg/L vs. 0.000 mg/L; P = .001), compared with COVID controls.

The PASC group also had elevated levels of CSF immune activation markers interferon gamma–inducible protein (IP-10), interleukin-8, and immunovascular markers vascular endothelial growth factor-C and VEGFR-1, although the differences with the control group were not statistically significant.

The timing of the onset of cognitive problems was also associated with higher levels of immune activation and immunovascular markers. Patients with brain fog that developed during the acute phase of COVID-19 had higher levels of CSF VEGF-C, compared with patients whose cognitive symptoms developed more than a month after initial COVID symptoms (173 pg/mL vs. 99 pg/mL; P = .048) and COVID controls (79 pg/mL; P = .048).

Acute onset cognitive PASC participants had higher CSF levels of IP-10 (P = .030), IL-8 (P = .048), placental growth factor (P = .030) and intercellular adhesion molecule-1 (P = .045), compared with COVID controls.

Researchers believe these new findings could mean that intrathecal immune activation and endothelial activation/dysfunction may contribute to cognitive PASC and that the mechanisms involved may be different in patients with acute cognitive PASC versus those with delayed onset.

“Our data suggests that perhaps in these people with more acute cognitive changes they don’t have the return to homeostasis,” Dr. Hellmuth said, while patients with delayed onset cognitive PASC had levels more in line with COVID patients who had no cognitive issues.

Screening patients for social needs and referring patients to resources should be a routine part of cancer care, said a physician who presented a study on the social needs of patients at the Society of Gynecologic Oncology’s 2022 Annual Meeting on Women’s Cancer held in March.

The study, by Anna L. Beavis, MD, MPH, a gynecologic oncologist with the Johns Hopkins Kelly Gynecologic Oncology Service, Baltimore, identified social needs, such as financial assistance and housing insecurity, among a group of 373 patients who completed a written assessment during regular office visits.

The patients were asked about food and housing insecurities, utility and transportation needs, and financial assistance. For some patients these are such dire issues, they actually affect patient outcomes.

While the results were limited to a single urban population and may not be generalizable to other populations, Dr. Beavis said the findings are noteworthy because for physicians, these are tangible items that can be addressed to improve patient outcomes.

“The greatest obstacle is not asking the questions, it’s in ensuring there are acceptable and effective mechanisms for referrals to resources. It is important to have a plan in place to refer patients to resources before beginning a screening program,” she said.

In an interview, Dr. Beavis said that screening and referring patients to resources should be a routine part of cancer care. In this study, 92% of patients completed the questionnaire in her office and the process doesn’t slow her clinic down, she said.

“Our findings demonstrate that social needs are prevalent, and screening for them should be a routine part of the standard of care for cancer patients,” Dr. Beavis said. “Social needs are also actionable for us as physicians, because we can address tangible, individual-level needs, such as food insecurity and transportation, through the provision of resources. These needs stand in contrast to the social determinants of health, which are community-level and require changes on a much larger scale through policy decisions.”

Of the 373 patients in the study group, 74 patients were identified as having at least one social need. Fifty-seven percent asked for a referral to a partner organization for resource assistance. Fifty-eight percent of the study group were White and 42% identified as patients of color, including Black, Asian, Hispanic, American Indian/Alaska Native, and multiple/other races.

“We’ve begun to assess patient satisfaction and have found that patients feel these questions are important – plus, they’re comfortable answering them,” she said.

Dr. Beavis’ study was funded by a grant from the American Cancer Society and Pfizer Global Medical Grants under the Addressing Racial Disparities in Cancer Care Competitive Grant Program.
