Systemic lupus erythematosus remains a treatment challenge, but a variety of drugs in the pipeline are set to target type I interferons, cytokines, and B cells, according to Richard Furie, MD, chief of the division of rheumatology at Northwell Health and professor of medicine at Hofstra University, Hempstead, N.Y.

In general, when treating patients with systemic lupus erythematosus (SLE), “we just don’t see satisfactory response rates,” Dr. Furie said in an online presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.

“I think the greatest unmet need is in lupus nephritis,” he said. The data show that not even one-third of patients are adequately responding to standard of care treatment. “We need to do better in lupus nephritis but also for those patients with moderate-severe manifestations outside the kidney.”

Patients with SLE have elevated levels of interferon-alpha, Dr. Furie noted. Data from recent studies show that interferon inhibitors can reduce clinical activity in SLE patients, he said.

“About two-thirds to three-quarters of lupus patients have evidence of interferon pathway activation,” he said. There are three types of interferons, and five subtypes of type I interferon, and all five subtypes of type I interferon bind to the same receptor, which is an important strategy for drug development.

In particular, recent phase 2 and 3 trials have focused on targeting type I interferons with anifrolumab, which blocks all five subtypes.

Dr. Furie cited “very robust results” from a phase 2 study. Results of two phase 3 trials of anifrolumab led to a split decision, but the totality of the data collected across the phase 2 and 3 studies points to a drug that is effective for patients with SLE. The two phase 3 studies were published in Lancet Rheumatology and the New England Journal of Medicine.

Dr. Furie also identified recent studies of baricitinib (Olumiant), which has the ability to target several different cytokines. A phase 2 study in 2018 showed a significant difference in SLE Responder Index between lupus patients who received 4 mg of baricitinib or placebo, and a phase 3 study is underway, he said.

For lupus nephritis, Dr. Furie cited the BLISS-LN trial, a 104-week, randomized trial of patients with active lupus nephritis. The group of patients who received belimumab (Benlysta), a monoclonal antibody that targets B-cell activating factor, in addition to standard therapy had significant improvements in renal responses, compared with standard therapy alone (43.0% vs. 32.3%). The outcome measure was Primary Efficacy Renal Response, defined as urinary protein/creatinine ratio <0.7, eGFR ≥60 mL/min per 1.73 m², confirmation on consecutive visits, and required tapering of background glucocorticoids.

Although belimumab was approved for SLE in 2011, the BLISS-LN study focused on SLE patients with active kidney disease. “Neutralizing B-cell activating factor and down-regulating autoreactive B-cell function in kidneys represented a compelling therapeutic approach to lupus nephritis,” he explained.

Voclosporin, distinct from cyclosporine, has also been studied in lupus nephritis, Dr. Furie said. Voclosporin offers several benefits over cyclosporine, including greater potency and a lower drug and metabolite load, as well as a more consistent pharmacokinetic and pharmacodynamic relationship, he said. In the phase 3 AURORA study, presented at this year’s EULAR congress, 40% of patients with lupus nephritis met the primary endpoint of a renal response at 52 weeks, compared with 22.5% of placebo patients.

Looking ahead to the treatment of SLE in 2021, “I feel very strongly that voclosporin will be approved for lupus nephritis,” he said. He also predicted that the use of belimumab will be officially extended for lupus nephritis and that anifrolumab will receive an approval for SLE patients.

In addition, the future may witness the increased use of biomarkers and development of more individualized therapy. These breakthroughs will yield better outcomes for all lupus patients, he said.

Dr. Furie disclosed relationships with GlaxoSmithKline, Genentech/Roche, Aurinia Pharmaceuticals, AstraZeneca/MedImmune, and Eli Lilly. Global Academy for Medical Education and this news organization are owned by the same parent company.

One year into the implementation of the Mission Act, the US Department of Veterans Affairs (VA) continues to expand a wide-ranging third-party-administered program to boost the access of veterans to the civilian medical system, a VA official told colleagues at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO). “VA has given to the third-party administrators what they do well, which is payment of claims, and VA has taken back what we think we can do better—scheduling, care coordination, and customer service,” said Elizabeth Brill, MD, MBA, chief medical officer and senior adviser to the acting assistant undersecretary for Health for Community Care.

            The 2 third-party contractors that run the Community Care Network (CCN) are Optum and TriWest. Both companies now proces patients at all VA medical facilities in the continental US. Optum serves all the states that are entirely (or mainly) in the Central and Eastern Time Zones—except for Texas—plus Puerto Rico, Washington D.C., and the US Virgin Islands. TriWest serves Texas, Hawaii, and the states that are entirely (or mainly) in the Mountain and Pacific Time Zones. The VA has not yet assigned any contractor for Alaska, Guam, American Samoa, and the Northern Mariana Islands.

“We have tried to consolidate as much as possible into the Community Care Network, pulling in a lot of services that were not previously covered, but it’s still not covering 100% of all services that veterans need outside VA medical centers,” said Brill.

Although the VA continues to rely on Veterans Care Agreements, in which health care providers contract directly with the VA, “the main focus of community care is the Community Care Network.” Said Brill. In a pair of regions—encompassing the Midwest, Northeast, and a few other states—90% of private health services are now provided through the network, she said.

One benefit of the new system is a better experience for the health care providers who work with Optum and TriWest. These administrators are responsible for finding providers and providing them with credentials based on appropriate criteria, Brill said. “In prior days, VA paid community providers directly, and some of you may be familiar with the delays that occurred in the system,” she said. “In the new system, we have third-party administrators who pay the providers quickly, and then VA pays them.”

Urgent care services are now available through CCN in most of the continental US and will be expanded to Texas, the Mountain region and the West by the end of September, she said. “We’ve been very pleased to see the response.” Meanwhile, flu shots for enrolled veterans are now available through the system via 60,000 locations.

There are requirements for private health care providers: They must meet new training requirements and submit claims within 180 days. Patients also must meet standards to get community care. For example, patients are eligible for access if the VA can’t serve them within a 30-minute drive time for primary care and mental health care and a 60-minute drive time for specialty care. Similarly, veterans are eligible if they cannot get an appointment within 20 days for primary and mental health care and 28 days for specialty care.

However, Brill insisted, the Mission Act is “not a move toward privatization. Internal VA care is just as important as external VA care,” she said. “This just gives them more choice.”

Brill also noted that there’s more to the Mission Act than expanded access. For example, an expansion of the Program of Comprehensive Assistance for Family Caregivers Program “will start kicking in this fall and the winter,” she said. It will include families of veterans from all eras of service.

The act also is designed to improve infrastructure, although the coronavirus pandemic may disrupt timing, she said. And, she added, it will strengthen the VA’s ability to recruit and keep health care providers through projects like a new scholarship program and more access to medical education debt reduction.

The rate of reduction in BCR-ABL1 value during the first 3 months of tyrosine kinase inhibitor therapy for chronic myeloid leukemia (CML) independently predicts the likelihood of sustained treatment-free remission (TFR) in eligible patients, a recent study shows.

The findings, along with the 10-year outcomes data from the phase 3 ENESTnd trial reported in 2019, can help with complex TFR decision-making, lead author Timothy P. Hughes, MD, said at the Society of Hematologic Oncology virtual meeting.

In 115 chronic-phase CML patients who were eligible and attempted TFR and had at least 12 months of follow-up, the probability of sustained TFR, defined as major molecular response off tyrosine kinase inhibitor therapy for 12 continuous months, was 55%. The time to halving of the BCR-ABL1 value after the start of therapy was the strongest independent predictor of success. Sustained TFR occurred in 80% of those in the first quartile of response time (halving time of less than 9.4 days), compared with 4% of those in the last quartile (halving time of more than 21.9 days), said Dr. Hughes of the South Australian Health and Medical Research Institute, Adelaide.

The model assumes molecular response of 4.5 status duration for 3 years – not just achievement of MR4.5.

“So that’s the other variable in this equation,’ he said.

The findings, which were published online Sept. 1 in Blood, were validated in an independent dataset.

Dr. Hughes and colleagues concluded that the data “support the critical importance of the initial kinetics of BCR-ABL1 decline for long-term outcomes.”

As an example of how the findings, along with those from ENESTnd, can help with TFR decision-making, Dr. Hughes presented a case involving a 59-year-old man with chronic-phase CML diagnosed 5 years prior with intermediate EUTOS long-term survival score (ELTS) and Sokal scores and a low Framingham Risk Score at diagnosis.

The patient was treated with frontline nilotinib at a standard dose of 300 mg twice daily and he responded well, achieving an MR4 molecular response after 18 months, and MR4.5 score at 2.5 years, which was maintained at 5 years.

“That’s a BCR-ABL level of less than 0.01% on the International Scale,” he said, noting that the patient’s BCR-ABL level started at 290% and had “a very, very steep fall to 0.26% at 3 months.”
 

Cardiovascular risk a factor

The patient was interested in attempting TFR when eligible, but had some vascular toxicity risks; he was being treated for hypertension and hypercholesterolemia and also had a family history of coronary artery disease.

Hypercholesterolemia is a recognized effect of nilotinib therapy, but both where being treated and were under control, Dr. Hughes noted.

The patient’s Framingham Risk Score had increased from 9 (low risk) to 16 (intermediate risk).

In determining whether to attempt TFR and closely monitor the patient or delay the attempt and perhaps either change to imatinib therapy or reduce the nilotinib dose, Dr. Hughes said it was important to consider the cardiovascular event risks as elucidated in ENESTnd.

It was hoped that the increased cardiovascular event risk demonstrated in years 0-5 of the study would diminish in the later years, but the 10-year finding actually showed persistent risk with nilotinib treatment: In years 0-5, 7.2%, 11.9% and 1.8% of patients in study arms receiving nilotinib 300 mg twice daily, nilotinib 400 mg twice daily, and imatinib 400 mg once daily, respectively, experienced a cardiovascular event. In years 5-10, the corresponding rates were 9.3%, 11.9%, and 1.8%.

“I think it’s an important message that the risk is there, at about the same rate, in the second 5 years,” said Dr. Hughes, the first author of the study.

The ENESTnd data also show how the Framingham Risk Score, which is based mainly on age, cholesterol levels, blood pressure, smoking history, and diabetes history, is associated with cardiovascular event rates in the treatment arms.

Patients with a low Framingham score who were receiving nilotinib had no greater risk of a cardiovascular event than did those receiving nilotinib during years 0-5.

“I think that makes it an attractive option in patients where you’re focusing on early achievement of deep molecular response and eligibility for treatment-free remission,” he said, adding that it’s a different story for those with intermediate or high Framingham scores, who have “ a really quite substantial” risk in the first 5 years.

The 5- to 10-year ENESTnd data, however, show that this lack of risk in low Framingham scores did not hold true. Even in those with a low-risk Framingham score, the overall 10-year event rate was 7.3% with nilotinib versus 1.1% with imatinib.

“This is an important message that it’s probably not appropriate to assume that your patient with low Framingham Risk Score at diagnosis is not having a higher risk of cardiovascular events in the period after 5 years out to 10 years,” Dr. Hughes said.

Of note, the case patient was considered eligible for TFR under all of the mandatory requirements of both the 2020 European LeukemiaNET recommendations and the National Comprehensive Cancer Network 2020 guideline for CML, which have slight differences but are “generally in accord.”

Based on those recommendations, the patient would be “eligible and probably recommended,” for TFR, he said.

The 10-year ENESTnd findings and the findings by Dr. Hughes and colleagues with respect to the tempo of early tyrosine kinase inhibitor response provide further confirmation of the patient’s eligibility.

“I would feel very happy to say to this patient: ‘You’ve got an excellent chance of achieving treatment-free remission today; going on with therapy is probably not in your interest given the risk of a cardiovascular event, so I’d recommend stopping,’ ” he said. “If the patient was not keen to stop, then I’d recommend switching to imatinib, because I don’t think we’re getting any great benefit from pushing on with nilotinib if the plan is not to attempt treatment-free remission.”

However, if the patient preferred another year of treatment before attempting TFR, it might be worth considering reducing the dose or switching to low-dose dasatinib, he noted, concluding that “the vascular risk profile and the prospect of treatment-free remission need to be carefully considered in every patient, particularly patients on second-generation drugs, before deciding whether to recommend treatment-free remission or extending therapy longer and whether it’s appropriate to just reduce the dose or switch.”

Dr. Hughes has received grant or research support and honoraria from Novartis and Bristol-Myers Squibb, and has been a paid consultant and advisory committee or review panel member for both companies.

The ENESTnd data also show how the Framingham Risk Score, which is based mainly on age, cholesterol levels, blood pressure, smoking history, and diabetes history, is associated with cardiovascular event rates in the treatment arms.

Patients with a low Framingham score who were receiving nilotinib had no greater risk of a cardiovascular event than did those receiving nilotinib during years 0-5.

“I think that makes it an attractive option in patients where you’re focusing on early achievement of deep molecular response and eligibility for treatment-free remission,” he said, adding that it’s a different story for those with intermediate or high Framingham scores, who have “ a really quite substantial” risk in the first 5 years.

The 5- to 10-year ENESTnd data, however, show that this lack of risk in low Framingham scores did not hold true. Even in those with a low-risk Framingham score, the overall 10-year event rate was 7.3% with nilotinib versus 1.1% with imatinib.

“This is an important message that it’s probably not appropriate to assume that your patient with low Framingham Risk Score at diagnosis is not having a higher risk of cardiovascular events in the period after 5 years out to 10 years,” Dr. Hughes said.

Of note, the case patient was considered eligible for TFR under all of the mandatory requirements of both the 2020 European LeukemiaNET recommendations and the National Comprehensive Cancer Network 2020 guideline for CML, which have slight differences but are “generally in accord.”

Based on those recommendations, the patient would be “eligible and probably recommended,” for TFR, he said.

The 10-year ENESTnd findings and the findings by Dr. Hughes and colleagues with respect to the tempo of early tyrosine kinase inhibitor response provide further confirmation of the patient’s eligibility.

“I would feel very happy to say to this patient: ‘You’ve got an excellent chance of achieving treatment-free remission today; going on with therapy is probably not in your interest given the risk of a cardiovascular event, so I’d recommend stopping,’ ” he said. “If the patient was not keen to stop, then I’d recommend switching to imatinib, because I don’t think we’re getting any great benefit from pushing on with nilotinib if the plan is not to attempt treatment-free remission.”

However, if the patient preferred another year of treatment before attempting TFR, it might be worth considering reducing the dose or switching to low-dose dasatinib, he noted, concluding that “the vascular risk profile and the prospect of treatment-free remission need to be carefully considered in every patient, particularly patients on second-generation drugs, before deciding whether to recommend treatment-free remission or extending therapy longer and whether it’s appropriate to just reduce the dose or switch.”

The rate of reduction in BCR-ABL1 value during the first 3 months of tyrosine kinase inhibitor therapy for chronic myeloid leukemia (CML) independently predicts the likelihood of sustained treatment-free remission (TFR) in eligible patients, a recent study shows.

The findings, along with the 10-year outcomes data from the phase 3 ENESTnd trial reported in 2019, can help with complex TFR decision-making, lead author Timothy P. Hughes, MD, said at the Society of Hematologic Oncology virtual meeting.

In 115 chronic-phase CML patients who were eligible and attempted TFR and had at least 12 months of follow-up, the probability of sustained TFR, defined as major molecular response off tyrosine kinase inhibitor therapy for 12 continuous months, was 55%. The time to halving of the BCR-ABL1 value after the start of therapy was the strongest independent predictor of success. Sustained TFR occurred in 80% of those in the first quartile of response time (halving time of less than 9.4 days), compared with 4% of those in the last quartile (halving time of more than 21.9 days), said Dr. Hughes of the South Australian Health and Medical Research Institute, Adelaide.

The model assumes molecular response of 4.5 status duration for 3 years – not just achievement of MR4.5.

“So that’s the other variable in this equation,’ he said.

The findings, which were published online Sept. 1 in Blood, were validated in an independent dataset.

Dr. Hughes and colleagues concluded that the data “support the critical importance of the initial kinetics of BCR-ABL1 decline for long-term outcomes.”

As an example of how the findings, along with those from ENESTnd, can help with TFR decision-making, Dr. Hughes presented a case involving a 59-year-old man with chronic-phase CML diagnosed 5 years prior with intermediate EUTOS long-term survival score (ELTS) and Sokal scores and a low Framingham Risk Score at diagnosis.

The patient was treated with frontline nilotinib at a standard dose of 300 mg twice daily and he responded well, achieving an MR4 molecular response after 18 months, and MR4.5 score at 2.5 years, which was maintained at 5 years.

“That’s a BCR-ABL level of less than 0.01% on the International Scale,” he said, noting that the patient’s BCR-ABL level started at 290% and had “a very, very steep fall to 0.26% at 3 months.”
 

Cardiovascular risk a factor

The patient was interested in attempting TFR when eligible, but had some vascular toxicity risks; he was being treated for hypertension and hypercholesterolemia and also had a family history of coronary artery disease.

Hypercholesterolemia is a recognized effect of nilotinib therapy, but both where being treated and were under control, Dr. Hughes noted.

The patient’s Framingham Risk Score had increased from 9 (low risk) to 16 (intermediate risk).

In determining whether to attempt TFR and closely monitor the patient or delay the attempt and perhaps either change to imatinib therapy or reduce the nilotinib dose, Dr. Hughes said it was important to consider the cardiovascular event risks as elucidated in ENESTnd.

It was hoped that the increased cardiovascular event risk demonstrated in years 0-5 of the study would diminish in the later years, but the 10-year finding actually showed persistent risk with nilotinib treatment: In years 0-5, 7.2%, 11.9% and 1.8% of patients in study arms receiving nilotinib 300 mg twice daily, nilotinib 400 mg twice daily, and imatinib 400 mg once daily, respectively, experienced a cardiovascular event. In years 5-10, the corresponding rates were 9.3%, 11.9%, and 1.8%.

“I think it’s an important message that the risk is there, at about the same rate, in the second 5 years,” said Dr. Hughes, the first author of the study.

The ENESTnd data also show how the Framingham Risk Score, which is based mainly on age, cholesterol levels, blood pressure, smoking history, and diabetes history, is associated with cardiovascular event rates in the treatment arms.

Researchers have identified five cognitive phenotypes among patients with multiple sclerosis (MS). The lead researcher described the clinical characteristics and MRI findings unique to each phenotype during a lecture at the Joint European Committee for Treatment and Research in Multiple Sclerosis–Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS–ACTRIMS) 2020, this year known as MSVirtual2020.

Between 40% and 70% of patients with MS have cognitive impairment, and the current results emphasize the importance of cognitive evaluation in clinical assessment, according to the investigators. “The identification of cognitive profiles can drive tailored rehabilitative strategies and introduce a new level in the evidence of disease activity assessment,” said Ermelinda De Meo, MD, a neurologist and PhD student at San Raffaele Hospital in Milan. Physical disability has been a major influence on treatment choices to date, but neurologists should consider that patients with minimal physical disability may have cognitive impairment, she added.

Information processing speed and episodic memory are the most commonly impaired cognitive functions in patients with MS, but executive function, verbal fluency, and visuospatial abilities also can be affected. Defining the neuroanatomical basis of cognitive dysfunction and developing effective strategies for rehabilitation requires a clearer understanding of cognitive deficits on an individual level, said Dr. De Meo.
 

A battery of clinical and imaging tests

She and her colleagues analyzed 1,212 patients with all forms of MS who presented to eight Italian centers. They also included 196 age-, sex-, and education-matched controls in their study. Patients underwent evaluation with the Expanded Disability Status Scale (EDSS) and a neuropsychological assessment that included Rao’s Brief Repeatable Battery and Stroop Test. The investigators also administered the Fatigue Severity Scale (FSS) and Montgomery Åsberg Depression Rating Scale (MADRS).

A subset of 172 patients with MS and 50 healthy controls underwent 3-T MRI. Dr. De Meo and colleagues examined T2 hyperintense and T1 hypointense lesion volumes. In addition, they quantified normalized brain volume, white matter volume, and gray matter volume and performed deep gray matter segmentation.

The subset of patients with MS who underwent MRI was not significantly different from the full cohort of patients with MS in the study, said Dr. De Meo. Because of the relatively small number of subjects who underwent MRI, she and her colleagues used simple MRI measures that are well validated, highly reproducible, and less susceptible to measurement error. “We know that advanced MRI technique could provide additional insights about the neural bases of these phenotypes. However, we can consider our MRI results as a starting point to better address future MRI studies,” she said.
 

Phenotypes had specific neural bases

The mean age did not differ significantly between patients (41.1 years) and controls (40.4 years). The sex ratio also was similar in both groups. Patients’ median EDSS score was 2.0, mean disease duration was 10.5 years, mean FSS score was 14.9, and mean MADRS score was 10.1.

The five cognitive phenotypes among patients with MS were characterized by preserved cognition (19%), mild verbal memory or semantic fluency impairment (30%), mild multidomain impairment (19%), severe attention or executive impairment with mild impairment of other domains (14%), and severe multidomain impairment (18%). Compared with patients with other phenotypes, those with preserved cognition and those with mild verbal memory or semantic fluency impairment were younger and had lower clinical disability and shorter disease duration. Patients with severe multidomain impairment had greater depressive symptoms. Patients with severe attention or executive phenotypes had higher FSS scores.

On MRI, patients with preserved cognition had lower thalamic volume than healthy controls. The researchers compared all other phenotypes to these two groups. Patients with mild verbal memory or semantic fluency impairment had reduced hippocampal volume. Patients with mild multidomain impairment had reduced cortical gray matter volume. Patients with severe attention or executive impairment had higher T2 lesion load. Patients with severe multidomain phenotypes had a broader pattern of atrophy, including decreased volume in the gray matter, white matter, thalamus, hippocampus, putamen, and nucleus accumbens.

“The present findings suggest that specific neural bases can be detected for each phenotype,” said Dr. De Meo. “Advanced and multimodal MRI techniques of analysis could help individuate the neural circuits and the neurotransmitter involved, also suggesting potential targets for the pharmacological treatment of cognitive decline.”
 

A need for longitudinal cohort studies

The study by Dr. De Meo and colleagues continues previous investigations of cognitive phenotypes in MS, which originally considered cognition to be either intact or impaired. Further research could “inform the development of targeted treatments for cognitive dysfunction in MS, which will ultimately bring us closer to a precision medicine model,” said Victoria M. Leavitt, PhD, of Columbia University Medical Center in New York.

“Clearly, we have to acknowledge that cognitive impairment is not a one-size-fits-all problem,” she added. “If a memory problem develops as a downstream consequence of language issues, targeting the hippocampus may not be effective. Separating patients into cognitive phenotype groups may be a key to understanding and identifying neural-level differences that underlie diverse cognitive issues.”

The evolution of cognitive changes over time must be understood clearly, because patients may develop memory impairment by separate pathways (e.g., focal lesions that precipitate hippocampal atrophy versus cortical thinning in parietal regions that result in white-matter disconnections among language regions), said Dr. Leavitt. “Longitudinal cohort studies and ... testable mechanistic models that incorporate multimodal neuroimaging metrics are an essential starting point. Machine-learning methods may also be a useful tool for beginning to look at how these different neuroimaging modalities work together dynamically to yield divergent cognitive phenotypes.”

The study was not supported by external funding. Dr. De Meo reported no relevant disclosures. Dr. Leavitt also reported no relevant disclosures.

Human papilloma virus (HPV)-mediated squamous cell carcinoma of the head and neck is on the rise, and the lack of herd immunity in young people will ensure growth for many years to come. “We’re really looking at another 30 to 40 years of HPV and oropharynx cancer growth,” said head and neck cancer surgeon Joseph Califano, MD, deputy director of the Moores Cancer Center at the University of California at San Diego, at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).

            Califano highlighted a 2019 study that estimated the number of diagnoses of oropharynx cancer cases in the US will grow by half to 30,000 by 2030, with the wide majority (about 25,000) in men. In 2016, the annual number of oropharynx cancer cases was 20,124. “The exponential increase in oropharynx cancer incidence in young white US men has ebbed, and modest increases are occurring/anticipated in cohorts born after 1955,” the study authors wrote.

            “Currently in the United States, we don't have adequate vaccine efficiency to provide herd immunity, particularly for young boys,” said Califano. He added that although HPV vaccinations may create herd immunity in 5 to 10 years, the cancers associated with HPV can take decades to develop so a dip in rates won’t come for many years.

            HPV-associated head and neck squamous cell cancer (HNSCC) affects people at a younger age when compared with other head and neck cancers—a decade or 2 earlier, according to Califano. Many patients are nonsmokers and nondrinkers, he said, and tumors may be painless and asymptomatic.

            It’s also becoming clear that the HPV-associated HNSCC can strike across a widespread area of the oropharynx, including the palatine and lingual tonsils, the nasal cavity, nasopharynx, and hypopharynx (the lower part of the voice box), he said. “It has an even larger footprint than we originally supposed when we realized HPV was a dominant mechanism for development of oropharyngeal cancer,” said Califano.

            Describing the extent of these cancers as an “epidemic,” Califono said a turning point in the understanding of HPV’s role in oropharynx cancers came in a “definitive” 2001 study that reported that HPV-positive patients were much more likely to develop oropharynx cancer (adjusted odds ratio, 14.4). Later research found that HPV-associated oropharynx cancers were more common than HPV-associated cervical cancer. Higher lifetime numbers of vaginal sex and oral sex partners are linked to higher risk of HPV-mediated HNSCC, he said, as is prolonged daily marijuana use.

            Califano emphasized the importance of counseling patients about sexual behaviors linked to the cancers, although it’s also important to consider that “the majority of patients don’t have these risk factors.”

            “The diagnosis is not an indication of infidelity or promiscuity,” he added, recalling that he saw at least one marriage dissolve because of “misunderstandings” regarding how the cancer is caused.  

            There are multiple treatment options. Early-stage oropharynx cancers can be treated with primary excision and staging neck dissection or radiotherapy. Multimodality therapy is appropriate for late-stage cancer and can include concurrent chemotherapy and radiation, primary excision, and treatment with concurrent cisplatinum, depending on the case. Also, “patients do really benefit if they’re enrolled in clinical trials.”

The good news is that HPV-positivity is associated with improved survival in oropharynx cancer, he said. He highlighted a 2019 study that said radiotherapy and cisplatin improve survival in HPV-positive oropharynx cancer patients. “This has become the de-facto standard of care for locally advanced, low-risk HPV-positive oropharynx cancer,” he said.

Human papilloma virus (HPV)-mediated squamous cell carcinoma of the head and neck is on the rise, and the lack of herd immunity in young people will ensure growth for many years to come. “We’re really looking at another 30 to 40 years of HPV and oropharynx cancer growth,” said head and neck cancer surgeon Joseph Califano, MD, deputy director of the Moores Cancer Center at the University of California at San Diego, at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).

            Califano highlighted a 2019 study that estimated the number of diagnoses of oropharynx cancer cases in the US will grow by half to 30,000 by 2030, with the wide majority (about 25,000) in men. In 2016, the annual number of oropharynx cancer cases was 20,124. “The exponential increase in oropharynx cancer incidence in young white US men has ebbed, and modest increases are occurring/anticipated in cohorts born after 1955,” the study authors wrote.

            “Currently in the United States, we don't have adequate vaccine efficiency to provide herd immunity, particularly for young boys,” said Califano. He added that although HPV vaccinations may create herd immunity in 5 to 10 years, the cancers associated with HPV can take decades to develop so a dip in rates won’t come for many years.

            HPV-associated head and neck squamous cell cancer (HNSCC) affects people at a younger age when compared with other head and neck cancers—a decade or 2 earlier, according to Califano. Many patients are nonsmokers and nondrinkers, he said, and tumors may be painless and asymptomatic.

            It’s also becoming clear that the HPV-associated HNSCC can strike across a widespread area of the oropharynx, including the palatine and lingual tonsils, the nasal cavity, nasopharynx, and hypopharynx (the lower part of the voice box), he said. “It has an even larger footprint than we originally supposed when we realized HPV was a dominant mechanism for development of oropharyngeal cancer,” said Califano.

            Describing the extent of these cancers as an “epidemic,” Califono said a turning point in the understanding of HPV’s role in oropharynx cancers came in a “definitive” 2001 study that reported that HPV-positive patients were much more likely to develop oropharynx cancer (adjusted odds ratio, 14.4). Later research found that HPV-associated oropharynx cancers were more common than HPV-associated cervical cancer. Higher lifetime numbers of vaginal sex and oral sex partners are linked to higher risk of HPV-mediated HNSCC, he said, as is prolonged daily marijuana use.

            Califano emphasized the importance of counseling patients about sexual behaviors linked to the cancers, although it’s also important to consider that “the majority of patients don’t have these risk factors.”

            “The diagnosis is not an indication of infidelity or promiscuity,” he added, recalling that he saw at least one marriage dissolve because of “misunderstandings” regarding how the cancer is caused.  

            There are multiple treatment options. Early-stage oropharynx cancers can be treated with primary excision and staging neck dissection or radiotherapy. Multimodality therapy is appropriate for late-stage cancer and can include concurrent chemotherapy and radiation, primary excision, and treatment with concurrent cisplatinum, depending on the case. Also, “patients do really benefit if they’re enrolled in clinical trials.”

The good news is that HPV-positivity is associated with improved survival in oropharynx cancer, he said. He highlighted a 2019 study that said radiotherapy and cisplatin improve survival in HPV-positive oropharynx cancer patients. “This has become the de-facto standard of care for locally advanced, low-risk HPV-positive oropharynx cancer,” he said.

Califano reported no relevant disclosures.

Most patients with chronic myeloid leukemia (CML) have a normal life expectancy thanks to dramatic improvements in treatments and outcomes over the past few decades, but new treatment approaches are needed for the subset who fail to respond or who develop resistance to existing treatments, according to Jorge Cortes, MD, director of the Georgia Cancer Center, Augusta.

Several novel tyrosine kinase inhibitors (TKIs) and combination therapies show promise in early studies, he said at the Society of Hematologic Oncology virtual meeting.
 

Asciminib

The allosteric inhibitor asciminib (ABL-001), for example, has completed phase 1/2 trials evaluating its use as a single agent and in combination with other therapies in the first-line setting, and a pivotal phase 3 study comparing it with bosutinib in the third-line setting is underway, Dr. Cortes said.

The rate of major cytogenetic response (MCyr) to asciminib in heavily pretreated patients in a phase 1/2 study published the New England Journal of Medicine was “very good” at 77%.

“And almost half [48%] of the patients had a major molecular response by 12 months,” he said, noting that even after excluding those who had a prior response but were enrolled because they couldn’t tolerate prior treatments, the MCyr and major molecular response (MMR) rates were 60% and 36%, respectively.

Asciminib also showed activity in patients with T315I mutations: The MCyr rate was 55% and the MMR rate at 12 months was 24%.

“Now, it is important to recognize that the doses that are required for inhibition – for getting these responses in [patients with] T315I – are higher than we need for the patients that do not have T315I, so it needs higher concentrations in vitro and it needs higher doses in vivo,” he said.

Also of note, the response rates were good both in those with two or fewer prior lines of therapy and in those with three or more (12-month MMR rates were 47% and 34%, respectively). For the latter, that’s “a very good rate, even though we’re only talking about 12 months of therapy,” Dr. Cortes said.

“And even in the patients who had been resistant or intolerant to ponatinib, 40% achieved a major molecular response, so very good results regardless of the number or type of tyrosine kinase inhibitors the patient had received, ” he added. The numbers in the group with T315I mutations are small, so further exploration is needed in subsequent studies, he noted.

The emergence of resistance is a concern with asciminib, but in a xenograft model, combining it with nilotinib appeared to prevent resistance. Therefore, the combination of asciminib and various TKIs has been explored in the clinic.

In a phase 1 study of asciminib and imatinib presented by Dr. Cortes at the European Hematology Association meeting in 2019, the complete cytogenetic response and MMR rates at 48 weeks were 50% and 42%, respectively.

“Now, this is a different type of population – perhaps a little more heavily pretreated than the ones who received single-agent asciminib, but it does show the potential for synergy, and importantly it was not associated with increased toxicity,” he said.
 

PF-114

Another agent in development is PF-114, a third-generation BCR-ABL inhibitor. It is a structural analogue of ponatinib that is modified to avoid inhibiting the VEGFR receptor in an effort to prevent “arterial occlusive and particularly hypertension, adverse events that we see with ponatinib,” he said.

In a phase 1 study of 51 patients with CML who failed at least two prior TKIs or had T315I mutation, the MCyr rate was 50% and the MMR rate was 36%. The drug was very well tolerated: The dose-limiting toxicity was skin toxicity involving psoriasiform lesions, which were manageable, he noted.

“Importantly ... there was no cardiovascular toxicity,” he added.

Those findings were presented at ASH 2018. The drug is now moving to a phase 2 study.
 

HQP1351 (GZD824)

The orally active, small-molecule BCR-ABL inhibitor HQP1351 is a third-generation TKI with activity against a broad spectrum of BCR-ABL mutations.

A phase 1 study of patients who were resistant to prior TKIs is complete, and results presented at ASH 2019 showed that most patients (67%) had only one or two prior therapies and 63% had T315I mutation. Response rates were better in the patients with T315I mutations (MCyr, 78% vs. 34%; MMR, 52% vs. 15% in 101 chronic phase patients).

The treatment was well tolerated, with grade 3 toxicity involving only hypertriglyceridemia, pyrexia, and proteinuria. No arterial occlusive events were reported.
 

K0706

K0706 is a selective inhibitor of BCR-ABL1 designed to inhibit enzymatic activity of BCR-ABL. The agent was efficacious and well tolerated with limited off-target activity in preclinical models. It can inhibit wild-type and mutant forms of BCR-ABL, but does not have activity against T315I.

Results of a phase 1 study presented at ASH in 2019 by Dr. Cortes showed that all the patients who received a dose of 174 mg or greater achieved or maintained a cytogenetic response at 6 months, and 50% achieved or maintained an MMR.

“This is a very good response rate in this heavily pretreated population,” he said.

Patients who received prior ponatinib had a somewhat lower response, but still, nearly 45% achieved an MCyr.

“So very good response rates, no arterial occlusive events, and phase 2 studies will be starting at the dose of 174 mg,” he said.
 

Additional combinations

As for combining TKIs with other agents, efforts are underway around the world to find ways to eradicate minimal residual disease. Examples include TKIs and imatinib, TKIs and azacitidine, and asciminib plus another TKI, to name a few.

One study from Germany showed that adding interferon leads to earlier achievement of MMR, but ultimately the responses were similar, Dr. Cortes said.

Adding venetoclax has shown some activity in the preclinical setting, and studies of that combination will be starting soon in the clinic, he noted.
 

Implications

The current survival probability in CML patients is 92% when considering CML-related deaths (68% when considering all-cause mortality), compared with 8% in the 1980s and 35%-43% in the early 1990s.

But the current benefits don’t extend to all patients, Dr. Cortes said.

“There are patients who actually end up having worse prognosis than we would expect,” he said, explaining that some CML-related deaths are attributable to lack of access to therapy and good care, but some are related to true poor prognosis, often caused by resistance or inability to tolerate treatments.

In fact, data from studies of various treatments show that almost 40% of patients on dasatinib or nilotinib change therapy by 5 years, and by 10 years, half of those randomized to nilotinib have changed therapy.

“So it is not uncommon that patients have to change therapy for one reason or another,” he said, adding that, as resistance persists through additional treatment options, the prognosis worsens significantly.

“It is important that we have new therapeutic options to be able to help these patients who are going to be in need of additional therapies,” he said.

Dr. Cortes has received grant or research support from Novartis, Pfizer, Takeda, and Sun Pharma, and he is a paid consultant for Pfizer, Novartis, and Takeda.

Three previously described clinical phenotypes of obstructive sleep apnea (OSA) have been validated in a large and diverse Hispanic/Latino community-based population for the first time, according to findings presented at the virtual annual meeting of the Associated Professional Sleep Societies.

The three OSA symptom profiles present in this population – labeled “minimally symptomatic,” “disturbed sleep,” and “daytime sleepiness” – are consistent with recent findings from the Sleep Apnea Global Interdisciplinary Consortium, which were published in Sleep, but there are notable differences in the prevalence of these clusters, with the minimally symptomatic cluster much more prevalent than in prior research, reported Kevin Gonzalez, of the University of California, San Diego.

“Other biopsychosocial factors may be contributing to OSA phenotypes among Hispanics and Latinos,” Mr. Gonzalez said in his presentation. Prior research to characterize the heterogeneity of sleep apnea has not included a diverse Latino population, he emphasized.

The adults studied were aged 18-74 years and participants in the multisite Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a comprehensive study of Hispanic/Latino health and disease in the United States. Their respiratory events were measured overnight in HCHS/SOL sleep reading centers with an ARES Unicorder 5.2, B-Alert. Sleep patterns and risk factors were assessed using the Sleep Heart Health Study Sleep Habits Questionnaire and the Epworth Sleepiness Scale.

Participants meeting the criteria for moderate to severe OSA (with an Apnea Hypopnea Index of 15 or above) were included in the analysis (n = 1,623). Their average age was 52.4 ± 13.9 years, and 34.1% were female.

To identify phenotype clusters, investigators performed a latent class analysis using 15 common OSA symptoms and a survey weighted to adjust for selection bias. The three clusters offering the “best” fit for the data aligned with the previously reported phenotypes and identified daytime sleepiness in 15.3%, disturbed sleep (insomnia-like symptoms) in 37.7%, and minimally symptomatic (a low symptom profile) in 46.9%.

These phenotypes were reported in the European Respiratory Journal in 2014 in a cluster analysis of data from a sleep apnea cohort in Iceland and later replicated in the analysis of data from the Sleep Apnea Global Interdisciplinary Consortium published in Sleep in 2018. The consortium study also added two additional phenotypes, labeled “upper airway symptoms dominant” and “sleepiness dominant.”

The prevalence of a “minimally symptomatic group” in the new analysis of the Hispanics/Latinos in the United States is much higher than reported in these prior studies, at least partly, the investigators believed, because the “prior studies were clinical samples, and the people who were minimally symptomatic didn’t get to the sleep centers,” Mr. Gonzalez said in an interview after the meeting.

Patients with a phenotype of daytime sleepiness – the most common phenotype in prior research – constituted only a minority in the Hispanic/Latino population, he said.

Alberto Ramos, MD, of the University of Miami and the principal investigator, said in an interview that the research team is currently analyzing “if and how these different [phenotypic] clusters could affect the incidence of comorbidities” recorded in the HCHS/SOL study, such as hypertension, diabetes, cardiovascular disease, and cognitive decline.

For now, he said, the findings suggest that OSA may be especially underrecognized in Hispanics and Latinos and that there is more research to be done to better identify and stratify patients with varying symptomatology for more personalized treatment and for clinical trial selection. “Maybe we should expand our criteria ... broaden our [recognition] of the presentation of sleep apnea and the symptoms associated with it, not only in Hispanics but maybe in the general population,” Dr. Ramos said.

In commenting on the study, Krishna M. Sundar, MD, FCCP, director of the Sleep-Wake Center at the University of Utah, Salt Lake City, said that insomnia and daytime sleepiness are “key associations with obstructive sleep apnea and may predict different outcomes with untreated OSA.” Such heterogeneity is “only beginning to be appreciated,” he said. “The expression of OSA with these symptoms points to how OSA impacts quality of life” and how symptomatology in addition to Apnea Hypopnea Index “may be an important determinant of treatment benefit and compliance.”

The investigators reported no relevant disclosures. Dr. Sundar said that he is cofounder of Hypnoscure, software for population management of sleep apnea, but with no monies received.

For now, he said, the findings suggest that OSA may be especially underrecognized in Hispanics and Latinos and that there is more research to be done to better identify and stratify patients with varying symptomatology for more personalized treatment and for clinical trial selection. “Maybe we should expand our criteria ... broaden our [recognition] of the presentation of sleep apnea and the symptoms associated with it, not only in Hispanics but maybe in the general population,” Dr. Ramos said.

In commenting on the study, Krishna M. Sundar, MD, FCCP, director of the Sleep-Wake Center at the University of Utah, Salt Lake City, said that insomnia and daytime sleepiness are “key associations with obstructive sleep apnea and may predict different outcomes with untreated OSA.” Such heterogeneity is “only beginning to be appreciated,” he said. “The expression of OSA with these symptoms points to how OSA impacts quality of life” and how symptomatology in addition to Apnea Hypopnea Index “may be an important determinant of treatment benefit and compliance.”

The investigators reported no relevant disclosures. Dr. Sundar said that he is cofounder of Hypnoscure, software for population management of sleep apnea, but with no monies received.
 

Three previously described clinical phenotypes of obstructive sleep apnea (OSA) have been validated in a large and diverse Hispanic/Latino community-based population for the first time, according to findings presented at the virtual annual meeting of the Associated Professional Sleep Societies.

The three OSA symptom profiles present in this population – labeled “minimally symptomatic,” “disturbed sleep,” and “daytime sleepiness” – are consistent with recent findings from the Sleep Apnea Global Interdisciplinary Consortium, which were published in Sleep, but there are notable differences in the prevalence of these clusters, with the minimally symptomatic cluster much more prevalent than in prior research, reported Kevin Gonzalez, of the University of California, San Diego.

“Other biopsychosocial factors may be contributing to OSA phenotypes among Hispanics and Latinos,” Mr. Gonzalez said in his presentation. Prior research to characterize the heterogeneity of sleep apnea has not included a diverse Latino population, he emphasized.

The adults studied were aged 18-74 years and participants in the multisite Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a comprehensive study of Hispanic/Latino health and disease in the United States. Their respiratory events were measured overnight in HCHS/SOL sleep reading centers with an ARES Unicorder 5.2, B-Alert. Sleep patterns and risk factors were assessed using the Sleep Heart Health Study Sleep Habits Questionnaire and the Epworth Sleepiness Scale.

Participants meeting the criteria for moderate to severe OSA (with an Apnea Hypopnea Index of 15 or above) were included in the analysis (n = 1,623). Their average age was 52.4 ± 13.9 years, and 34.1% were female.

To identify phenotype clusters, investigators performed a latent class analysis using 15 common OSA symptoms and a survey weighted to adjust for selection bias. The three clusters offering the “best” fit for the data aligned with the previously reported phenotypes and identified daytime sleepiness in 15.3%, disturbed sleep (insomnia-like symptoms) in 37.7%, and minimally symptomatic (a low symptom profile) in 46.9%.

These phenotypes were reported in the European Respiratory Journal in 2014 in a cluster analysis of data from a sleep apnea cohort in Iceland and later replicated in the analysis of data from the Sleep Apnea Global Interdisciplinary Consortium published in Sleep in 2018. The consortium study also added two additional phenotypes, labeled “upper airway symptoms dominant” and “sleepiness dominant.”

The prevalence of a “minimally symptomatic group” in the new analysis of the Hispanics/Latinos in the United States is much higher than reported in these prior studies, at least partly, the investigators believed, because the “prior studies were clinical samples, and the people who were minimally symptomatic didn’t get to the sleep centers,” Mr. Gonzalez said in an interview after the meeting.

Patients with a phenotype of daytime sleepiness – the most common phenotype in prior research – constituted only a minority in the Hispanic/Latino population, he said.

Alberto Ramos, MD, of the University of Miami and the principal investigator, said in an interview that the research team is currently analyzing “if and how these different [phenotypic] clusters could affect the incidence of comorbidities” recorded in the HCHS/SOL study, such as hypertension, diabetes, cardiovascular disease, and cognitive decline.

This year’s virtual meeting of the European Association for the Study of Diabetes (EASD) offers new data and insights regarding the use of newer glucose-lowering agents for treating people with, and without, diabetes, as well as updates on diabetes technology, a symposium on COVID-19, and much more.

The meeting takes place live online September 22-25, Central European time, because it was to have been located in Vienna before the COVID-19 pandemic, which forced nearly all medical meetings to go virtual. However, as in years past, videos of all the sessions will be available to registrants for later viewing and to the public a month after the meeting ends. The registration fee is less than half the cost for previous years.

In fact, EASD was better prepared to go virtual than many other medical societies, and not just because they had more time to plan since the pandemic began, EASD president Stefano Del Prato, MD, told Medscape Medical News. “Starting in 2013 we already had a virtual congress in parallel to the face-to-face meeting. Everything at the congress was simultaneously available on streaming. That made us more confident in what we could achieve with a virtual meeting.”

Last year, the EASD meeting held in Barcelona was the first for which the number of virtual attendees equaled the number who attended in person, about 15,000 each. Another 80,000 people have accessed the video content in the year since.

“Maybe this is a unique occasion for reaching out to a really global audience,” said Del Prato, professor of endocrinology and metabolism and chief of the section of diabetes at the University of Pisa School of Medicine, Italy.  

EASD Honorary Secretary Mikael Rydén, MD, PhD, the meeting’s program chair, told Medscape Medical News, “I’m really looking forward to this meeting because of the interactivity. I hope that, lacking the possibility of having a physical meeting, this is absolutely the best one can do.”
 

More cardiovascular and renal outcomes for SGLT2 inhibitors 

The impact of the sodium-glucose cotransporter 2 (SGLT2) inhibitor drug class beyond glucose-lowering has dominated the agenda of diabetes meetings for the past 5 years, and this EASD is no exception.

Here, new data will be presented for the previously reported EMPEROR-Reduced trial of empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) for patients with heart failure with or without diabetes; DAPA-CKD, on renal outcomes for dapagliflozin (Farxiga, AstraZeneca); and renal results from the VERTIS CV outcome trial of ertugliflozin (Steglatro, Merck).

Regarding DAPA-CKD, Del Prato noted, “We will have a greater opportunity ... to go deeper into the results during a 1-hour session.”

A related session, a joint EASD/European Society of Cardiology (ESC) symposium on the “dawn of cardiovascular risk reduction in type 2 diabetes” will review the development of SGLT2 inhibitors and the data accumulated for the drug class over the past 5 years since the landmark EMPA-REG OUTCOME trial was first reported at EASD in 2015.

The joint symposium, Rydénsaid, will be “extremely important for clinicians. It’s a revolution in type 2 diabetes treatment, and perhaps in those without diabetes who have heart failure...It’s not about a single company, but experts involved in all the different trials of the different SGLT2 inhibitors...We’re still seeing the huge impact that the SGLT2 inhibitors have made, and the incretins as well. We’re still living in these rumbling years after these huge trials.”

Del Prato also named that symposium as a meeting highlight.

“From a clinical point of view, I think the EMPA-REG 5-year session will be of great interest. That was really a turning point not only in the field of diabetes, but also in cardiology and nephrology. I think that will be a great opportunity to see how quickly and how importantly SGLT2 inhibition has turned into a great opportunity for many people.”
 

Who’s “right” – diabetologists or cardiologists?

Another session likely to draw a crowd of clinicians is a debate about which guidelines are “right”: the ESC’s, which advise first-line use of an SGLT2 inhibitor or glucagon-like peptide-1 (GLP-1) agonist for patients with established CVD or those at high risk, or the more conservative EASD/American Diabetes Association’s, which still advise metformin as first-line therapy for type 2 diabetes.

Rydén, who is professor and senior consultant in endocrinology at the Karolinska University Hospital and Karolinska Institute, Sweden, commented, “The difference is in how aggressive to be in treatment and when adding drugs...I think we have slightly different ways of seeing things and how we implement them.”

Del Prato noted, “We need to clear the fog about what are the current indications for people with diabetes. There is definitely a point of contact between cardiology and diabetology. ... We like to split [the disciplines] up, but discussion is a good way to get people thinking.”

“It will be very important to address the importance of glucose control but yet also leverage a new form of treatment that will have properties above and beyond glucose-lowering capacity.”
 

Other big trial results: CGM after MI, semaglutide for obesity

Other major new trial results to be presented in dedicated sessions include LIBERATES (Improving Glucose Control in Patients With Diabetes Following Myocardial Infarction: The Role of a Novel Glycaemic Monitoring), and STEP program (Semaglutide for the Treatment of Obesity).

LIBERATES will compare glycemic control with the Abbott FreeStyle Libre 14-day sensor and standard fingerstick glucose monitoring versus blinded continuous glucose monitoring (CGM) for 90 days after a heart attack. It was a late addition to the meeting program, Rydén noted.

The semaglutide study is looking at weight loss associated with a higher dose of the GLP-1 agonist than is currently approved for diabetes, similar to the way in which liraglutide was developed as an obesity agent after first gaining approval for type 2 diabetes.

Regarding semaglutide, Rydén said, “I’ve heard this one is quite efficient. It will be interesting.”
 

Personalized medicine, COVID-19, intermittent fasting, and much more

Both Rydén and Del Prato also said they were looking forward to a joint EASD/American Diabetes Association symposium on a newly launched precision medicine initiative. The session will include talks on subclassifications of diabetes, genetics, and precision diabetes medicine in practice, as well as lessons on the latter from Greenland.

Rydén noted, “I think it’s interesting for everyone, from the primary healthcare physician to the basic scientist. We’re trying to understand why we have this huge diabetic panorama and how do we identify the subject who should have a specific treatment, or perhaps [will] develop a specific complication of diabetes.”

This field, he predicted, “will grow enormously in the next 10 years.”

Del Prato pointed out, “Diabetes is more heterogeneous than we tend to believe for both types. Better guidance for individualization of treatments could be a great opportunity. ... Ways to better genotype and phenotype the population are becoming less expensive and easier to access. It will be a different way to treat diabetes in the future.”

Other noteworthy conference sessions will address COVID-19 and diabetes, intermittent fasting, new technologies, diabetes and cancer, the role of liver surveillance in patients with diabetes, medicines that can cause diabetes, exercise in type 1 diabetes, and the burden of hypoglycemia.  

There will also be opportunities for networking, Del Prato said. “You’ll be able to walk around with your own avatar. You’ll be assisted by [artificial intelligence] to build your own program based on what you’ve been following. You can participate in discussion rooms. You can walk in and out.”

“We hope people will appreciate the science and the spirit of the congress – mingling, interacting, chatting to start discussion and maybe collaboration. It will be lots of fun. I would like to invite all Medscape readers to come and register.

Rydén has reported being a consultant, speaker, and/or advisory board member for Novo Nordisk, Eli Lilly, Boehringer Ingelheim, Novartis, and AstraZeneca. Del Prato has reported being a speaker, advisory board member, and/or receiving research support from AstraZeneca, Boehringer Ingelheim, Eli Lilly, MSD, Novartis, Novo Nordisk, Sanofi, Servier, and Takeda.

Current guidelines recommend a 5-minute rest period before a blood pressure screening measurement, but that might not be necessary for all patients.

In a prospective crossover study, average differences in blood pressure measurements obtained after 0 or 2 minutes of rest were not significantly different than readings obtained after the recommended 5 minutes of rest in adults with systolic blood pressure below 140 mm Hg.

“The average differences in BP by rest period were small, and BPs obtained after shorter rest periods were noninferior to those obtained after 5 minutes when SBP is below 140,” Tammy M. Brady, MD, PhD, Johns Hopkins University, Baltimore, said in an interview.

“This suggests shorter rest times, even 0 minutes, may be reasonable for screening when the initial SBP is below 140,” said Brady.

She presented her research at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension..
 

A challenging recommendation

The 5-minute rest period is “challenging” to implement in busy clinical settings, Dr. Brady said. The researchers therefore set out to determine the effect of no rest and the effect of a shorter rest period (2 minutes) on blood pressure screening.

They recruited 113 adults (mean age, 55; 64% women, 74% Black) with SBP that ranged from below 115 mm Hg to above 145 mm Hg and with diastolic BP that ranged from below 75 mm Hg to above 105 mm Hg. About one-quarter (28%) had SBP in the stage 2 hypertension range (at least 140 mm Hg).

They obtained four sets of automated BP measurements after 5, 2, or 0 minutes of rest. All participants had their BP measured after a second 5-minute rest period as their last measurement to estimate repeatability.

Overall, there was no significant difference in the average BP obtained at any of the rest periods.

After the first and second 5-minute rest period, BPs were 127.5/74.7 mm Hg and 127.0/75.6 mm Hg, respectively. After 2 and 0 minutes of rest, BPs were 126.8/73.7 mm Hg and 126.5/74.0 mm Hg.

When looking just at adults with SBP below 140 mm Hg, there was no more than an average difference of ±2 mm Hg between BPs obtained at the 5-minute resting periods, compared with the shorter resting periods.

However, in those with SBP below 140 mm Hg, BP values were significantly different (defined as more than ±2 mm Hg) with shorter rest periods, “suggesting that shorter rest periods were in fact inferior to resting for 5 minutes in these patients,” Dr. Brady said.
 

More efficient, economic

“Economics play a significant role in blood pressure screenings, as clinics not as well-funded may find it especially challenging to implement a uniform, 5-minute rest period before testing, which could ultimately reduce the number of patients able to be screened,” Dr. Brady added in a conference statement.

“While our study sample was small, a reasonable approach based on these findings would be to measure blood pressure after minimal to no rest, and then repeat the measurements after 5 minutes only if a patient is found to have elevated blood pressure,” she said.

Weighing in on the results, Karen A. Griffin, MD, who chairs the AHA council on hypertension, said that “reducing the rest period to screen an individual for hypertension may result in faster throughput in the clinic and confer a cost savings.”

“At the present time, in order to maintain the clinic flow, some clinics use a single, often times ‘nonrested’ BP measurement as a screen, reserving the 5-minute rest automated-office BP measurement for patients found to have an elevated screening BP,” noted Dr. Griffin, professor of medicine, Loyola University Medical Center, Maywood, Ill.

“Nevertheless, even if limiting the use of automated-office BP to those who fail the initial screening BP, a cost savings would still be realized by reducing the currently recommended 5-minute rest to 2 minutes and have the most impact in very busy, less well-funded clinics,” said Dr. Griffin.

She cautioned, however, that further studies in a larger population will be needed before making a change to current clinical practice guidelines.

The study had no specific funding. Dr. Brady and Dr. Griffin have no relevant disclosures.

Current guidelines recommend a 5-minute rest period before a blood pressure screening measurement, but that might not be necessary for all patients.

In a prospective crossover study, average differences in blood pressure measurements obtained after 0 or 2 minutes of rest were not significantly different than readings obtained after the recommended 5 minutes of rest in adults with systolic blood pressure below 140 mm Hg.

“The average differences in BP by rest period were small, and BPs obtained after shorter rest periods were noninferior to those obtained after 5 minutes when SBP is below 140,” Tammy M. Brady, MD, PhD, Johns Hopkins University, Baltimore, said in an interview.

“This suggests shorter rest times, even 0 minutes, may be reasonable for screening when the initial SBP is below 140,” said Brady.

She presented her research at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension..
 

A challenging recommendation

The 5-minute rest period is “challenging” to implement in busy clinical settings, Dr. Brady said. The researchers therefore set out to determine the effect of no rest and the effect of a shorter rest period (2 minutes) on blood pressure screening.

They recruited 113 adults (mean age, 55; 64% women, 74% Black) with SBP that ranged from below 115 mm Hg to above 145 mm Hg and with diastolic BP that ranged from below 75 mm Hg to above 105 mm Hg. About one-quarter (28%) had SBP in the stage 2 hypertension range (at least 140 mm Hg).

They obtained four sets of automated BP measurements after 5, 2, or 0 minutes of rest. All participants had their BP measured after a second 5-minute rest period as their last measurement to estimate repeatability.

Overall, there was no significant difference in the average BP obtained at any of the rest periods.

After the first and second 5-minute rest period, BPs were 127.5/74.7 mm Hg and 127.0/75.6 mm Hg, respectively. After 2 and 0 minutes of rest, BPs were 126.8/73.7 mm Hg and 126.5/74.0 mm Hg.

When looking just at adults with SBP below 140 mm Hg, there was no more than an average difference of ±2 mm Hg between BPs obtained at the 5-minute resting periods, compared with the shorter resting periods.

However, in those with SBP below 140 mm Hg, BP values were significantly different (defined as more than ±2 mm Hg) with shorter rest periods, “suggesting that shorter rest periods were in fact inferior to resting for 5 minutes in these patients,” Dr. Brady said.
 

More efficient, economic

“Economics play a significant role in blood pressure screenings, as clinics not as well-funded may find it especially challenging to implement a uniform, 5-minute rest period before testing, which could ultimately reduce the number of patients able to be screened,” Dr. Brady added in a conference statement.

“While our study sample was small, a reasonable approach based on these findings would be to measure blood pressure after minimal to no rest, and then repeat the measurements after 5 minutes only if a patient is found to have elevated blood pressure,” she said.

Weighing in on the results, Karen A. Griffin, MD, who chairs the AHA council on hypertension, said that “reducing the rest period to screen an individual for hypertension may result in faster throughput in the clinic and confer a cost savings.”

Insomnia disorder appears to play a causal role in the development of new stressful life events, especially “dependent” events for which individuals are at least partly responsible, said the investigators of an ongoing longitudinal study of people who have experienced involuntary job loss.

The “stress-generation hypothesis” has been applied for several decades in the context of depression. It posits that depressed individuals generate more stressful life events – events that create family conflict or disrupt careers, for instance – than individuals who are not depressed.

The new analysis of individuals with involuntary job loss suggests that the same can be said of insomnia. “Insomnia disorder is associated with fatigue, daytime sleepiness, impaired concentration, and difficulties in emotional regulation,” Iva Skobic, MSPH, MA, a PhD student at the University of Arizona, Tucson, said at the virtual annual meeting of the Associated Professional Sleep Societies.

“These may lead to impaired decision-making, interpersonal conflicts, difficulty meeting deadlines and keeping commitments, and other sources [of stressful life events],” she said. “This extension of the stress-generation hypothesis has important implications for harm reduction interventions for insomnia disorder.”

Investigators conducted a cross-lagged panel analysis using baseline and 3-month follow-up data from 137 individuals who completed a standardized, textual life event measure called the Life Events and Difficulties Schedule after having lost their jobs involuntarily. Participants were interviewed and their events were rated for severity by a consensus panel using operationalized criteria. The analysis employed linear regression controlling for covariates (age, gender, and race) and logistic regression that controlled for insomnia at baseline. Insomnia disorder was defined as meeting ICSD-2/3 criteria using the Duke Structured Interview for Sleep Disorders.

The findings: Insomnia disorder at baseline predicted the number of stressful life events (either dependent or interpersonal) generated within 3 months (beta, 0.70; standard error, 0.31; Tscore, 2.27; P = .03). Conversely, the number of stressful events at baseline did not predict insomnia (odds ratio, 0.97; 95% confidence interval, 0.73-1.29). There also was a trend toward increased generation of dependent events specifically among those with insomnia disorder.

Participants were a mean age of 42 years, and all had been in their previous place of employment for at least 6 months. Nearly 60% met the diagnostic threshold for insomnia at baseline. They were part of a larger ongoing study examining the linkages between job loss and sleep disturbances, obesity, and mental health – the Assessing Daily Activity Patterns through Occupational Transitions (ADAPT) study, supported by the National Heart, Lung, and Blood Institute.

This analysis on insomnia was completed before the COVID-19 pandemic began, but it and other analyses soon to be reported are highly relevant to the economic climate, said Patricia Haynes, PhD, principal investigator of ADAPT and a coauthor of the insomnia study, in an interview after the meeting.

Insomnia is a frequent comorbidity of depression and shares many of its symptoms, from increased fatigue to emotional dysregulation and an increased risk of maladaptive coping strategies. “Interestingly, the literature on the stress-generation hypothesis posits that these very symptoms are on the casual pathway between depression and stressful life events,” said Ms. Skobic at the meeting.

In commenting on the study, Krishna M. Sundar, MD, medical director of the Sleep-Wake Center at the University of Utah, Salt Lake City, noted that the analysis did not include any measure of the severity of insomnia. Still, he said, “finding an association [with stress generation] at [just] 3 months with the presence of insomnia disorder is quite interesting.”

There were higher rates of insomnia in the sample than depression, Dr. Haynes said, but the analysis did not control for depression or take it into account.

“We know [from prior research] that stress clearly leads to insomnia. The big [takeaway] here is that insomnia can also lead to more stress,” she said. “It’s important to think of it as a reciprocal relationship. If we can potentially treat insomnia, we may be able to stop that cycle of other stressful events that affect both [the individuals] and others as well.”
