Multiple psychiatric groups have asked the U.S. Food and Drug Administration to consider holding a public meeting about its approach to risk management of the schizophrenia drug clozapine, which is effective but carries serious risks, including death.

In a Feb. 14 letter, the groups asked the FDA to reconsider its new risk evaluation and mitigation strategy (REMS) for clozapine because of concerns it had the potential to cause abrupt discontinuation of the medication.

The groups cite an Institute for Safe Medication Practices (ISMP) report of a 40-year-old woman who was a long-time clozapine user, had a cardiac arrest, and died after she stopped taking the drug because her psychiatrist was unable to register for the updated version of the REMS.

“It is unacceptable for a REMS with unproven effectiveness at meeting its goal to carry risks of interruptions that can result in rehospitalization, acute exacerbation of psychosis, increased risk of suicide, and potentially fatal orthostatic hypotension/bradycardic syndromes associated with incorrect restarts,” the groups said in the letter.

“We feel certain that this case reported in the literature is not the only serious adverse outcome from the REMS and the transition,” they added.

The letter was signed by the American Psychiatric Association, the American Association for Community Psychiatry, the American Psychiatric Nurses Association, the College of Psychiatric and Neurologic Pharmacists, the National Alliance on Mental Illness, the National Association of State Mental Health Program Directors, and the National Council for Mental Wellbeing.

Clozapine can decrease the neutrophil count, which can lead to severe neutropenia, serious infection, and death. Consequently, the FDA put additional safety measures in place governing clozapine prescribing.

In 2015, a centralized clozapine REMS replaced separate prescribing registries that the drug manufacturers maintained. There were technical issues with the 2015 start-up of that website, including data migration problems and long call wait times, the FDA said.

Subsequently, the drug’s manufacturers then decided to change the REMS platform, which created new issues that led to high call volume and long wait times for clinicians and pharmacists who were trying to enroll.
 

Maintaining access

In November 2021, the FDA announced it would put some aspects of a planned switch on hold. A month later, the agency made further modifications to its plan.

The FDA said it would exercise “enforcement discretion” to try to maintain access to clozapine amid hitches with the REMS transition efforts. The agency also said at the time that it would not object if pharmacists dispensed clozapine without the usual authorization. In addition, wholesalers could ship the drug to pharmacies and health care settings without confirming REMS enrollment.

The FDA also held two December meetings to allow various stakeholders to air concerns.

In their letter, the APA and other groups asked if the FDA intends to continue with accommodations, such as allowing pharmacies to order clozapine from wholesalers without restriction.

“We do not feel the issues are resolved,” the groups said.

A single injection of the experimental agent nirsevimab ahead of respiratory syncytial virus (RSV) season protects healthy infants from lower respiratory tract infections associated with the pathogen, according to the results of a phase 3 study.

A previously published trial showed that a single dose of nirsevimab was effective in preterm infants. The ability to protect all babies from RSV, which causes bronchiolitis and pneumonia and is a leading cause of hospitalization for this age group, “would be a paradigm shift in the approach to this disease,” William Muller, MD, PhD, of the Lurie Children’s Hospital of Chicago and a coauthor of the study, said in a statement.

The primary endpoint of the study was medically attended lower respiratory tract infections linked to RSV. The single injection of nirsevimab was associated with a 74.5% reduction in such infections (P < .001), according to Dr. Muller’s group, who published their findings March 2 in the New England Journal of Medicine.

Nirsevimab, a monoclonal antibody to the RSV fusion protein being developed by AstraZeneca and Sanofi, has an extended half-life, which may allow one dose to confer protection throughout a season. The only approved option to prevent RSV, palivizumab (Synagis), is used for high-risk infants, and five injections are needed to cover a viral season.
 

Nearly 1,500 infants in more than 20 countries studied

To assess the effectiveness of nirsevimab in late-preterm and term infants, investigators at 160 sites randomly assigned 1,490 babies born at a gestational age of at least 35 weeks to receive an intramuscular injection of nirsevimab or placebo.

During the 150 days after injection, medically attended RSV-associated lower respiratory tract infections occurred in 12 of 994 infants who received nirsevimab, compared with 25 of 496 babies who received placebo (1.2% vs. 5%).

Six of 994 infants who received nirsevimab were hospitalized for RSV-associated lower respiratory tract infections, compared with 8 of 496 infants in the placebo group (0.6% vs. 1.6%; P = .07). The proportion of children hospitalized for any respiratory illness as a result of RSV was 0.9% among those who received nirsevimab, compared with 2.2% among those who received placebo.

Serious adverse events occurred in 6.8% of the nirsevimab group and 7.3% of the placebo group. None of these events, including three deaths in the nirsevimab group, was considered related to nirsevimab or placebo, according to the researchers. One infant who received nirsevimab had a generalized macular rash without systemic features that did not require treatment and resolved in 20 days, they said.

Antidrug antibodies were detected in 6.1% of the nirsevimab group and in 1.1% of the placebo group. These antidrug antibodies tended to develop later and did not affect nirsevimab pharmacokinetics during the RSV season, the researchers reported. How they might affect subsequent doses of nirsevimab is not known, they added.

In a separate report in the journal, researcher Joseph Domachowske, MD, SUNY Upstate Medical University, Syracuse, New York, and colleagues described safety results from an ongoing study of nirsevimab that includes infants with congenital heart disease, chronic lung disease, and prematurity.

In this trial, infants received nirsevimab or palivizumab, and the treatments appeared to have similar safety profiles, the authors reported.

Other approaches to RSV protection include passive antibodies acquired from maternal vaccination in pregnancy and active vaccination of infants.

The publication follows news last month that GlaxoSmithKline is pausing a maternal RSV vaccine trial, which “had the same goal of protecting babies against severe RSV infection,” said Louis Bont, MD, PhD, with University Medical Center Utrecht, the Netherlands.

RSV infection is one of the deadliest diseases during infancy, and the nirsevimab trial, conducted in more than 20 countries, is “gamechanging,” Dr. Bont told this news organization. Still, researchers will need to monitor for RSV resistance to this treatment, he said.

Whether nirsevimab prevents the development of reactive airway disease and asthma is another open question, he said.

“Finally, we need to keep in mind that RSV mortality is almost limited to the developing world, and it is unlikely that this novel drug will become available to these countries in the coming years,” Dr. Bont said. “Nevertheless, nirsevimab has the potential to seriously decrease the annual overwhelming number of RSV infected babies.”

Nirsevimab may have advantages in low- and middle-income countries, including its potential to be incorporated into established immunization programs and to be given seasonally, said Amy Sarah Ginsburg, MD, MPH, of the University of Washington, Seattle. “However, cost remains a significant factor, as does susceptibility to pathogen escape,” she said.

MedImmune/AstraZeneca and Sanofi funded the nirsevimab studies. UMC Utrecht has received research grants and fees for advisory work from AstraZeneca for RSV-related work by Bont.

PHOENIX – In a 15-month phase 4 trial, an inexpensive intervention that can be explained in a single office visit reduced severe exacerbations and improved asthma control in patient populations that suffer disproportionately from the disease. This easy-to-implement strategy achieved benefits similar to those from previous studies that prompted new treatment recommendations for moderate-to-severe asthma.

The findings were reported Feb. 26 in the Late-Breaking Oral Abstracts session at the American Academy of Allergy, Asthma, and Immunology (AAAAI) 2022 Meeting, coinciding with publication in the New England Journal of Medicine.

Black and Latino patients are under-represented in asthma research trials yet visit the emergency room and die from asthma-related complications at more than twice the rates of their White counterparts. Prior efforts to reduce this burden “have been expensive, difficult, and mostly unsuccessful,” Juan-Carlos Cardet, MD, MPH, assistant professor of internal medicine at the University of South Florida, Tampa, told attendees.

Dr. Cardet and his colleagues, led by principal investigator Elliot Israel, MD, of Brigham & Women’s Hospital, Boston, Mass., designed a study with input and financial support from the Patient-Centered Outcomes Research Institute (PCORI). The trial recruited 603 Black and 598 Latino adults with moderate-to-severe asthma. About a fifth were current or former smokers, and many lived in smoking environments. All had poorly controlled asthma or at least one severe asthma attack in the previous year. Each participant held prescriptions for daily inhaled corticosteroids (ICS) with or without long-acting beta-agonists.

Current guidelines recommend daily ICS in all but the mildest asthma cases, yet adherence is poor. Patients generally take medicine when they perceive a need, and since asthma is episodic, “most people don’t like to take controller therapy for asthma,” Dr. Cardet told this news organization in advance of his meeting presentation. Rather, many asthma patients use quick-relief therapies, such as albuterol or nebulizers, on an as-needed basis.

Prior research showed that clinical outcomes can improve with a strategy called Single Maintenance and Reliever Therapy (SMART). In this approach, an ICS (budesonide) is combined with a long-acting beta-agonist (formoterol) into a single inhaler so that patients automatically receive inhaled steroids whenever they treat their symptoms with quick-relief medication. The ICS-formoterol strategy looked promising in studies published more than a decade ago, and those results have prompted an update in national treatment guidelines, but “it’s been difficult to get [the strategy] into the clinic,” Dr. Cardet told this news organization. “FDA cautions against as-needed use of ICS-formoterol. That’s a big reason. Insurance companies won’t pay for it.”

Unlike the SMART studies, which asked participants to replace their usual controller and rescue therapies with the all-in-one inhaler, Black and Latino patients in the new trial were told to continue with their usual asthma care. On top of usual care, half of the participants were randomly assigned to receive one-time instruction around use of a controller medication (beclomethasone; Qvar) supplied by study investigators. “Essentially we told them to keep doing what your doctor tells you to do, but whenever you use a puff of rescue therapy, puff yourself with this Qvar, and if you use the nebulizer, puff yourself five times with the Qvar,” Dr. Cardet said.

This approach, called Patient Activated Reliever-Triggered Inhaled Corticosteroid (PARTICS), was explained to patients through a video in English and Spanish. “All of this we instructed in a single study visit,” Dr. Cardet said.

The PARTICS intervention reduced severe asthma exacerbations by 15% (0.13 exacerbations per patient per year) – on par with the estimated 0.12 exacerbations per patient annualized reduction with SMART. In addition, the PARTICS group had:

• better asthma control (3.4-point increase on the Asthma Control Test, vs. a 2.5-point increase in the usual-care group);
• improved quality of life (0.12-point increase on the Asthma Symptom Utility Index, vs. a 0.08-point increase in the usual-care group);
• fewer self-reported days lost from work, school, and usual activities (13.4 days, vs. 16.8 days in the usual-care group).

Addressing long-standing challenges with controller therapy compliance, this was a real-world strategy “to get more inhaled steroids in [asthma patients] on a regular basis,” Brian Vickery, MD, director of the Food Allergy Center at Emory University + Children’s Healthcare of Atlanta, said during the meeting session Q&A. Dr. Vickery was not involved in the study. “And you see an effect size that rivaled previous studies, which suggests to me that the improvement is in the inhaled steroid component and not necessarily the long-acting beta-agonist.”

The study team hopes these results can be implemented on a health care system level. “If it stays just in a journal, it’s not going to do anything. We want to help people. We want to bring it to clinic,” Dr. Cardet said in an interview.

The study was supported by a Patient-Centered Outcomes Research Institute (PCORI) award to Israel and by grants from the National Institute of Allergy and Infectious Diseases and the American Lung Association–American Academy of Allergy, Asthma, and Immunology to Dr. Cardet. QVAR and QVAR RediHaler inhalers were provided free of charge, and funding for the AssistRx pharmacy was provided by Teva Pharmaceuticals. NIOX VERO devices for measuring exhaled nitric oxide were provided free of charge by Circassia Pharmaceuticals. Dr. Cardet reported honoraria from AstraZeneca and Genentech for work in advisory boards and from GlaxoSmithKline for educational lectures on asthma, all unrelated to the AAAAI presentation. Dr. Vickery has disclosed no relevant financial relationships.

PHOENIX – In a 15-month phase 4 trial, an inexpensive intervention that can be explained in a single office visit reduced severe exacerbations and improved asthma control in patient populations that suffer disproportionately from the disease. This easy-to-implement strategy achieved benefits similar to those from previous studies that prompted new treatment recommendations for moderate-to-severe asthma.

The findings were reported Feb. 26 in the Late-Breaking Oral Abstracts session at the American Academy of Allergy, Asthma, and Immunology (AAAAI) 2022 Meeting, coinciding with publication in the New England Journal of Medicine.

Black and Latino patients are under-represented in asthma research trials yet visit the emergency room and die from asthma-related complications at more than twice the rates of their White counterparts. Prior efforts to reduce this burden “have been expensive, difficult, and mostly unsuccessful,” Juan-Carlos Cardet, MD, MPH, assistant professor of internal medicine at the University of South Florida, Tampa, told attendees.

Dr. Cardet and his colleagues, led by principal investigator Elliot Israel, MD, of Brigham & Women’s Hospital, Boston, Mass., designed a study with input and financial support from the Patient-Centered Outcomes Research Institute (PCORI). The trial recruited 603 Black and 598 Latino adults with moderate-to-severe asthma. About a fifth were current or former smokers, and many lived in smoking environments. All had poorly controlled asthma or at least one severe asthma attack in the previous year. Each participant held prescriptions for daily inhaled corticosteroids (ICS) with or without long-acting beta-agonists.

Current guidelines recommend daily ICS in all but the mildest asthma cases, yet adherence is poor. Patients generally take medicine when they perceive a need, and since asthma is episodic, “most people don’t like to take controller therapy for asthma,” Dr. Cardet told this news organization in advance of his meeting presentation. Rather, many asthma patients use quick-relief therapies, such as albuterol or nebulizers, on an as-needed basis.

Prior research showed that clinical outcomes can improve with a strategy called Single Maintenance and Reliever Therapy (SMART). In this approach, an ICS (budesonide) is combined with a long-acting beta-agonist (formoterol) into a single inhaler so that patients automatically receive inhaled steroids whenever they treat their symptoms with quick-relief medication. The ICS-formoterol strategy looked promising in studies published more than a decade ago, and those results have prompted an update in national treatment guidelines, but “it’s been difficult to get [the strategy] into the clinic,” Dr. Cardet told this news organization. “FDA cautions against as-needed use of ICS-formoterol. That’s a big reason. Insurance companies won’t pay for it.”

Unlike the SMART studies, which asked participants to replace their usual controller and rescue therapies with the all-in-one inhaler, Black and Latino patients in the new trial were told to continue with their usual asthma care. On top of usual care, half of the participants were randomly assigned to receive one-time instruction around use of a controller medication (beclomethasone; Qvar) supplied by study investigators. “Essentially we told them to keep doing what your doctor tells you to do, but whenever you use a puff of rescue therapy, puff yourself with this Qvar, and if you use the nebulizer, puff yourself five times with the Qvar,” Dr. Cardet said.

This approach, called Patient Activated Reliever-Triggered Inhaled Corticosteroid (PARTICS), was explained to patients through a video in English and Spanish. “All of this we instructed in a single study visit,” Dr. Cardet said.

The PARTICS intervention reduced severe asthma exacerbations by 15% (0.13 exacerbations per patient per year) – on par with the estimated 0.12 exacerbations per patient annualized reduction with SMART. In addition, the PARTICS group had:

• better asthma control (3.4-point increase on the Asthma Control Test, vs. a 2.5-point increase in the usual-care group);
• improved quality of life (0.12-point increase on the Asthma Symptom Utility Index, vs. a 0.08-point increase in the usual-care group);
• fewer self-reported days lost from work, school, and usual activities (13.4 days, vs. 16.8 days in the usual-care group).

Addressing long-standing challenges with controller therapy compliance, this was a real-world strategy “to get more inhaled steroids in [asthma patients] on a regular basis,” Brian Vickery, MD, director of the Food Allergy Center at Emory University + Children’s Healthcare of Atlanta, said during the meeting session Q&A. Dr. Vickery was not involved in the study. “And you see an effect size that rivaled previous studies, which suggests to me that the improvement is in the inhaled steroid component and not necessarily the long-acting beta-agonist.”

The study team hopes these results can be implemented on a health care system level. “If it stays just in a journal, it’s not going to do anything. We want to help people. We want to bring it to clinic,” Dr. Cardet said in an interview.

The study was supported by a Patient-Centered Outcomes Research Institute (PCORI) award to Israel and by grants from the National Institute of Allergy and Infectious Diseases and the American Lung Association–American Academy of Allergy, Asthma, and Immunology to Dr. Cardet. QVAR and QVAR RediHaler inhalers were provided free of charge, and funding for the AssistRx pharmacy was provided by Teva Pharmaceuticals.

Survival after in-hospital cardiac arrest was roughly one-third lower in patients with COVID-19 infections compared to uninfected patients, based on data from nearly 25,000 individuals.

Survival rates of less than 3% were reported in the United States and China for patients who suffered in-hospital cardiac arrest (IHCA) while infected with COVID-19 early in the pandemic, but the data came from small, single-center studies in overwhelmed hospitals, wrote Saket Girotra, MD, of the University of Iowa, Iowa City, and fellow American Heart Association Get With the Guidelines–Resuscitation Investigators. Whether these early reports reflect the broader experience of patients with COVID-19 in hospitals in the United States remains unknown.

In a study published as a research letter in JAMA Network Open, the researchers reviewed data from the American Heart Association Get With the Guidelines–Resuscitation registry. The registry collects detailed information on patients aged 18 years and older who experience cardiac arrest at participating hospitals in the United States. The study population included 24,915 patients aged 18 years and older from 286 hospitals who experienced IHCA during March–December 2020. The mean age of the patients was 64.7 years; 61.1% were White, 24.8% were Black, 3.8% were of other race or ethnicity, and 10.3% were of unknown race or ethnicity.

The primary outcomes were survival to discharge and return of spontaneous circulation (ROSC) for at least 20 minutes.

A total of 5,916 patients (23.7%) had suspected or confirmed COVID-19 infections, and infected patients were more likely to be younger, male, and Black. Patients with COVID-19 infections also were significantly more likely than noninfected patients to have nonshockable rhythm, pneumonia, respiratory insufficiency, or sepsis, and to be on mechanical ventilation or vasopressors when the IHCA occurred, the researchers noted.

Survival rates to hospital discharge were 11.9% for COVID-19 patients, compared with 23.5% for noninfected patients (adjusted relative risk, 0.65; P < .001). ROSC was 53.7% and 63.6%, for infected and noninfected patients, respectively (aRR, 0.86; P < .001).

COVID-19 patients also were more likely than noninfected patients to receive delayed defibrillation, the researchers said. “Although delays in resuscitation, especially defibrillation, may have contributed to lower survival, the negative association of COVID-19 with survival in this study was consistent across subgroups, including patients who received timely treatment with defibrillation and epinephrine.”

The extremely low survival rate in early pandemic studies likely reflected the overwhelming burden on health systems at the time, the researchers said in their discussion.

The study findings were limited by several factors, including potential confounding from unmeasured variables, the use of a quality improvement registry that may not reflect nonparticipating hospitals, and potential false-positive COVID-19 cases. However, the result support findings from recent studies of multiple centers and extend clinical knowledge by comparing infected and noninfected patients from a larger group of hospitals than previously studied, the researchers said.

“We believe that these data will be relevant to health care providers and hospital administrators as the COVID-19 pandemic continues,” they concluded.
 

Think beyond COVID-19 for cardiac care

“Early during the pandemic, questions were raised whether COVID-19 patients should be treated with CPR,” Dr. Girotra said in an interview. “This was because initial studies had found a dismal survival of 0%-3% in COVID patients treated with CPR. The potential of transmitting the virus to health care professionals during CPR further heightened these concerns. We wanted to know whether the poor survival reported in these initial studies were broadly representative.”

Dr. Girotra said that some of the study findings were surprising. “We found that of all patients with IHCA in 2020 in our study, one in four were suspected or confirmed to have COVID-19 infection. We were surprised by the magnitude of COVID’s impact on the cardiac arrest incidence.”

The implications for clinical decision-making are to think outside of COVID-19 infection, said Dr. Girotra. In the current study, “Although overall survival of cardiac arrest in COVID-positive patients was 30% lower, compared to non-COVID patients, it was not as poor as previously reported. COVID-19 infection alone should not be considered the sole factor for making decisions regarding CPR.

“Over the past 2 decades, we have experienced large gains in survival for in-hospital cardiac arrest. However, the COVID-19 pandemic has eroded these gains,” said Dr. Girotra. “Future studies are needed to monitor the impact of any new variants on cardiac arrest care,” as well as studies “to see whether we return to the prepandemic levels of IHCA survival once the pandemic recedes.”

Dr. Girotra has no relevant financial disclosures.

A new statistical analysis of an existing meta-analysis reaffirms a finding that hospitalized patients with COVID-19 who are on simple oxygen or noninvasive ventilation can benefit from treatment with the arthritis drug tocilizumab (Actemra) in conjunction with corticosteroids. But the report also casts doubt on the effectiveness of tocilizumab in patients who are on ventilators.

“Clinicians should prescribe steroids and tocilizumab for hospitalized patients needing simple oxygen or noninvasive ventilation,” epidemiologist and study coauthor James (Jay) Brophy, MD, PhD, of McGill University, Montreal, said in an interview. “Further research is required to answer the question of whether tocilizumab is beneficial in patients requiring invasive ventilation, and consideration of participation in further tocilizumab studies seems reasonable.”

The new analysis was published Feb. 28, 2022, in JAMA Network Open.

The initial meta-analysis, published in 2021 in JAMA, was conducted by the WHO Rapid Evidence Appraisal for COVID-19 Therapies Working Group. It analyzed the results of 27 randomized trials that explored the use of interleukin-6 antagonists, including tocilizumab, and found that “28-day all-cause mortality was lower among patients who received IL-6 antagonists, compared with those who received usual care or placebo (summary odds ratio, 0.86). The summary ORs for the association of IL-6 antagonist treatment with 28-day all-cause mortality were 0.78 with concomitant administration of corticosteroids versus 1.09 without administration of corticosteroids.”

For the new report, researchers conducted a Bayesian statistical analysis of 15 studies within the meta-analysis that specifically examined the use of the rheumatoid arthritis drug tocilizumab. “Bayesian analysis allows one to make direct probability statements regarding the exact magnitude and the certainty of any benefit,” Dr. Brophy said. “This provides clinicians with the information they require to make well-informed decisions.”

The analysis estimated that the probability of a “clinically meaningful association” (absolute mortality risk difference, >1%) because of use of tocilizumab was higher than 95% in patients receiving simple oxygen and higher than 90% in those receiving noninvasive ventilation. But the probability was only about 67% higher in those receiving invasive mechanical ventilation.

Also, the researchers estimated that about 72% of future tocilizumab studies in patients on invasive mechanical ventilation would show a benefit.

The new analysis findings don’t add much to existing knowledge, said nephrologist David E. Leaf, MD, MMSc, of Harvard Medical School, Boston, who’s studied tocilizumab in COVID-19.

“The signal seems to be consistent that there is a greater benefit of tocilizumab in less ill patients than those who are more ill – e.g., those who are receiving invasive mechanical ventilation,” Dr. Leaf said in an interview. “This is interesting because in clinical practice the opposite approach is often undertaken, with tocilizumab use only being used in the sickest patients, even though the patients most likely to benefit seem to be those who are less ill.”

Clinically, he said, “hospitalized patients with COVID-19 should receive tocilizumab unless they have a clear contraindication and assuming it can be administered relatively early in their disease course. Earlier administration, before the onset of irreversible organ injury, is likely to have greater benefit.”

Dr. Leaf also noted it’s unknown whether the drug is helpful in several groups – patients presenting later in the course of COVID-19 illness, patients with additional infections, and immunocompromised patients.

It’s also not clear if tocilizumab benefits patients with lower levels of C-reactive protein, Shruti Gupta, MD, MPH, a nephrologist at Brigham and Women’s Hospital in Boston, said in an interview. The RECOVERY trial, for example, limited subjects to those with C-reactive protein of at least 75 mg/L.

Dr. Leaf and Dr. Gupta coauthored a 2021 cohort study analyzing mortality rates in patients with COVID-19 who were treated with tocilizumab versus those who were not.

No study funding was reported. Dr. Brophy, Dr. Leaf, and Dr. Gupta disclosed no relevant financial relationships. One study author reported participating in one of the randomized clinical trials included in the analysis.

U.S. prices for brand-name lung cancer drugs generally increased between 2015 and 2020 without evidence of price competition, a cross-sectional analysis revealed.

The findings underscore the need for price reform, according to the investigators, who analyzed prices for 17 brand-name medications used for treating metastatic non–small cell lung cancer (NSCLC).

Prices increased during the study period and correlated within each drug class, Aakash Desai, MBBS, and colleagues from the Mayo Clinic, Rochester, Minn., found.

“Because numerous new drugs have been approved for the treatment of NSCLC in recent years, we sought to specifically study the price competition among drugs used to treat this cancer subtype,” they explained, noting that for most drug classes price increases outpaced changes in the consumer price index for prescription medications and the inflation rate.

The findings were published Jan. 25, 2022, in JAMA Network Open.

Multiple brand-name medications across several drug classes, including four immune checkpoint inhibitors (pembrolizumab, nivolumab, atezolizumab, and durvalumab), five epidermal growth factor receptor inhibitors (gefitinib, afatinib, erlotinib, osimertinib, and dacomitinib), five anaplastic lymphoma kinase inhibitors (crizotinib, ceritinib, alectinib, brigatinib, and lorlatinib), two BRAF inhibitors (dabrafenib, vemurafenib), and one MEK inhibitor (trametinib) were included in the analysis.

Median Pearson correlation coefficients approached 1.0 for all drug classes, indicating that prices increased despite within-class drug competition. Median values ranged from 0.898 for epidermal growth factor inhibitors to 0.999 for anaplastic lymphoma kinase inhibitors and BRAF and MEK inhibitors, the investigators found.

Median compounded annual growth rates (CAGRs) were 1.81% for immune checkpoint inhibitors, 2.56% for epidermal growth factor receptor inhibitors, 2.46% for anaplastic lymphoma kinase and ROS1 inhibitors, and 3.06% for BRAF and MEK inhibitors.

“With the exception of the immunotherapy class, the median cost CAGR outpaced the annual growth rate of the consumer price index for prescription drugs at 2.10% and, for all classes, the average yearly inflation rate of 1.75% during the same period,” they wrote.

Also of note, only one price decrease occurred among all therapeutic classes studied.

“This was observed for erlotinib between 2019 and 2020, and it corresponded with the introduction of a generic competitor to the market,” the authors said.

The findings are reminiscent of an earlier study that showed a 25% increase in the price of 24 patented injectable anticancer agents in the United States over a period of 8 years after launch.

“These increases in cost were not offset by supplemental U.S. Food and Drug Administration approvals, new competitors, or new off-label indications. Thus, price increases over time were not substantially reduced by market competition and increased at similar rates among drugs within the same class,” they wrote, adding that “although one might expect oncology drug prices to decrease over time after market entry, the list price of most anticancer agents increases paradoxically.”

The “lock-step price increases” observed without evidence of price competition in this analysis raise concerns about the affordability of promising oncology drugs, they said, concluding that “academic, industry, and government partnerships should be developed to address the high costs of prescription oncology drugs, which may soon be unaffordable for most patients if the trends discovered in the present study continue.”

U.S. prices for brand-name lung cancer drugs generally increased between 2015 and 2020 without evidence of price competition, a cross-sectional analysis revealed.

The findings underscore the need for price reform, according to the investigators, who analyzed prices for 17 brand-name medications used for treating metastatic non–small cell lung cancer (NSCLC).

Prices increased during the study period and correlated within each drug class, Aakash Desai, MBBS, and colleagues from the Mayo Clinic, Rochester, Minn., found.

“Because numerous new drugs have been approved for the treatment of NSCLC in recent years, we sought to specifically study the price competition among drugs used to treat this cancer subtype,” they explained, noting that for most drug classes price increases outpaced changes in the consumer price index for prescription medications and the inflation rate.

The findings were published Jan. 25, 2022, in JAMA Network Open.

Multiple brand-name medications across several drug classes, including four immune checkpoint inhibitors (pembrolizumab, nivolumab, atezolizumab, and durvalumab), five epidermal growth factor receptor inhibitors (gefitinib, afatinib, erlotinib, osimertinib, and dacomitinib), five anaplastic lymphoma kinase inhibitors (crizotinib, ceritinib, alectinib, brigatinib, and lorlatinib), two BRAF inhibitors (dabrafenib, vemurafenib), and one MEK inhibitor (trametinib) were included in the analysis.

Two preprint studies released on Feb. 26 offer additional evidence that the coronavirus pandemic started at a market in Wuhan, China.

By analyzing data from several sources, scientists concluded that the virus came from animals and spread to humans in late 2019 at the Huanan Seafood Market. They added that no evidence supported a theory that the virus came from a laboratory in Wuhan.

“When you look at all the evidence together, it’s an extraordinarily clear picture that the pandemic started at the Huanan market,” Michael Worobey, D.Phil., a co-author on both studies and an evolutionary biologist at the University of Arizona, told the New York Times.

The two reports haven’t yet been peer-reviewed or published in a scientific journal. They were posted on Zenodo, an open-access research repository operated by CERN.

In one study, researchers used spatial analysis to show that the earliest COVID-19 cases, which were diagnosed in December 2019, were linked to the market. Researchers also found that environmental samples that tested positive for the SARS-CoV-2 virus were associated with animal vendors.

In another study, researchers found that two major viral lineages of the coronavirus resulted from at least two events when the virus spread from animals into humans. The first transmission most likely happened in late November or early December 2019, they wrote, and the other likely happened a few weeks later.

Several of the researchers behind the new studies also published a review last summer that said the pandemic originated in an animal, likely at a wildlife market. At that time, they said the first known case was a vendor at the Huanan market.

The new findings provide the strongest evidence yet that the pandemic had animal-related origins, Dr. Worobey told CNN. He called the results a “game, set and match” for the theory that the pandemic began in a lab.

“It’s no longer something that makes sense to imagine that this started any other way,” he said.

In a separate line of research, scientists at the Chinese CDC conducted a new analysis of samples collected at the market in January. They found that the samples included the two main lineages of the coronavirus. They posted the results in a report on the Research Square preprint server Feb. 26.

“The beauty of it is how simply it all adds up now,” Jeremy Kamil, a virologist at Louisiana State University Health Sciences, who wasn’t involved with the new studies, told the New York Times.

The initial spread of the coronavirus was like a firework, Dr. Worobey told CNN, starting at the market and exploding outward. The “overwhelming majority” of cases were specifically linked to the western section of the market, where most of the live-mammal vendors were located, the study authors wrote. Then COVID-19 cases spread into the community from there, and the pattern of transmission changed by January or February 2020.

When researchers tested surfaces at the market for coronavirus genetic material, one stall had the most positives, including a cage where raccoon dogs had been kept.

The study authors said the findings highlight the urgent need to pay attention to situations where wild animals and humans interact closely on a daily basis.

“We need to do a better job of farming and regulating these wild animals,” Robert Garry, one of the co-authors and a professor of microbiology and immunology at the Tulane University School of Medicine, told CNN.

That could include better infrastructure in places like markets where viruses spill over from animals to humans, he said. Surveillance is also key in preventing future pandemics by detecting new respiratory diseases in humans, isolating patients, and sequencing new virus strains.

“This is not the last time this happens,” he said.

A study of the nasal microbiome helped researchers predict recurrent polyps in chronic rhinosinusitis patients with more than 90% accuracy, based on data from 85 individuals.

Chronic rhinosinusitis with nasal polyps (CRSwNP) has a significant impact on patient quality of life, but the underlying mechanism of the disease has not been well studied, and treatment options remain limited, wrote Yan Zhao, MD, of Capital Medical University, Beijing, and study coauthors.

Previous research has shown that nasal microbiome composition differs in patients with and without asthma, and some studies suggest that changes in microbiota could contribute to CRSwNP, the authors wrote. The researchers wondered if features of the nasal microbiome can predict the recurrence of nasal polyps after endoscopic sinus surgery and serve as a potential treatment target.

In a study in Allergy, the researchers examined nasal swab samples from 85 adults with CRSwNP who underwent endoscopic sinus surgery between August 2014 and March 2016 at a single center in China. The researchers performed bacterial analysis and gene sequencing on all samples.

The patients ranged in age from 18-73 years, with a mean age of 46 years, and included 64 men and 21 women. The primary outcome was recurrence of polyps. Of the total, 39 individuals had recurrence, and 46 did not.

When the researchers compared microbiota from swab samples of recurrent and nonrecurrent patients, they found differences in composition based on bacterial genus abundance. “Campylobacter, Bdellovibrio, and Aggregatibacter, among others, were more abundant in swabs from CRSwNP recurrence samples, whereas Actinobacillus, Gemella, and Moraxella were more abundant in non-recurrence samples,” they wrote.

The researchers then tested their theory that distinct nasal microbiota could be a predictive marker of risk for future nasal polyp recurrence. They used a training set of 48 samples and constructed models from nasal microbiota alone, clinical features alone, and both together.

The regression model identified Porphyromonas, Bacteroides, Moryella, Aggregatibacter, Butyrivibrio, Shewanella, Pseudoxanthomonas, Friedmanniella, Limnobacter, and Curvibacter as the most important taxa that distinguished recurrence from nonrecurrence in the specimens. When the model was validated, the area under the curve was 0.914, yielding a predictor of nasal polyp recurrence with 91.4% accuracy.

“It is highly likely that proteins, nucleic acids, and other small molecules produced by nasal microbiota are associated with the progression of CRSwNP,” the researchers noted in their discussion of the findings. “Further, the nasal microbiota could maintain a stable community environment through the secretion of various chemical compounds and/or inflammatory factors, thus playing a central role in the development of CRSwNP.”

The study findings were limited by several factors, including the analysis of nasal flora only at the genus level in the screening phase, the use only of bioinformatic analysis for recurrence prediction, and the inclusion only of subjects from a single center, the researchers noted. Future studies should combine predictors to increase accuracy and include deeper sequencing, they said. However, the results support data from previous studies and suggest a strategy to meet the need for predictors of recurrence in CRSwNP, they concluded.

“There is a critical need to understand the role of the upper airway microbiome in different phenotypes of CRS,” said Emily K. Cope, PhD, assistant director at the Pathogen and Microbiome Institute, Northern Arizona University, Flagstaff, in an interview. “This was one of the first studies to evaluate the predictive power of the microbiome in recurrence of a common CRS phenotype – CRS with nasal polyps,” she said. “Importantly, the researchers were able to predict recurrence of polyps prior to the disease manifestation,” she noted.  

“Given the nascent state of current upper airway microbiome research, I was surprised that they were able to predict polyp recurrence prior to disease manifestation,” Dr. Cope said. “This is exciting, and I can imagine a future where we use microbiome data to understand risk for disease.”

What is the take-home message for clinicians? Although the immediate clinical implications are limited, Dr. Cope expressed enthusiasm for additional research. “At this point, there’s not a lot we can do without validation studies, but this study is promising. I hope we can understand the mechanism that an altered microbiome might drive (or be a result of) polyposis,” she said.

The study was supported by the National Natural Science Foundation of China, the program for the Changjiang scholars and innovative research team, the Beijing Bai-Qian-Wan talent project, the Public Welfare Development and Reform Pilot Project, the National Science and Technology Major Project, and the CAMS Innovation Fund for Medical Sciences. The researchers and Dr. Cope disclosed no financial conflicts.

Legionnaires’ disease (LD) in the United States appears to be on an upswing that started in 2003, according to a study from the Centers for Disease Control and Prevention.

The reasons for this increased incidence are unclear, the researchers write in Emerging Infectious Diseases.

“The findings revealed a rising national trend in cases, widening racial disparities between Black or African American persons and White persons, and an increasing geographic focus in the Middle Atlantic, the East North Central, and New England,” lead author Albert E. Barskey, MPH, an epidemiologist in CDC’s Division of Bacterial Diseases, Atlanta, said in an email.

“Legionnaires’ disease cannot be diagnosed based on clinical features alone, and studies estimate that it is underdiagnosed, perhaps by 50%,” he added. “Our findings may serve to heighten clinicians’ awareness of this severe pneumonia’s etiology, so with an earlier correct diagnosis, appropriate treatment can be rendered sooner.”

Mr. Barskey and his coauthors at CDC – mathematical statistician Gordana Derado, PhD, and epidemiologist Chris Edens, PhD – used surveillance data to investigate the incidence of LD in the U.S. over time. They compared LD incidence in 2018 with average incidence between 1992 and 2002. The incidence data, from over 80,000 LD cases, were age-standardized using the 2005 U.S. standard population as the reference.

The researchers analyzed LD data reported to CDC by the 50 states, New York City, and Washington, D.C., through the National Notifiable Diseases Surveillance System. They performed regression analysis to identify the optimal year when population parameters changed, and for most analyses, they compared 1992-2002 data with 2003-2018 data.
 

Legionnaires’ disease up in various groups

• The overall age-standardized average incidence grew from 0.48 per 100,000 people during 1992-2002 to 2.71 per 100,000 in 2018 (incidence risk ratio, 5.67; 95% confidence interval, 5.52-5.83).
• LD incidence more than quintupled for people over 34 years of age, with the largest relative increase in those over 85 (RR, 6.50; 95% CI, 5.82-7.27).
• Incidence in men increased slightly more (RR, 5.86; 95% CI, 5.67-6.05) than in women (RR, 5.29; 95% CI, 5.06-5.53).
• Over the years, the racial disparity in incidence grew markedly. Incidence in Black persons increased from 0.47 to 5.21 per 100,000 (RR, 11.04; 95% CI, 10.39-11.73), compared with an increase from 0.37 to 1.99 per 100,000 in White persons (RR, 5.30; 95% CI, 5.12-5.49).
• The relative increase in incidence was highest in the Northeast (RR, 7.04; 95% CI, 6.70-7.40), followed by the Midwest (RR, 6.13; 95% CI, 5.85-6.42), the South (RR, 5.97; 95% CI, 5.67-6.29), and the West (RR, 3.39; 95% CI, 3.11-3.68).

Most LD cases occurred in summer or fall, and the seasonal pattern became more pronounced over time. The average of 57.8% of cases between June and November during 1992-2002 grew to 68.9% in 2003-2018.

Although the study “was hindered by incomplete race and ethnicity data,” Mr. Barskey said, “its breadth was a strength.”
 

Consider legionella in your diagnosis

In an interview, Paul G. Auwaerter, MD, a professor of medicine and the clinical director of the Division of Infectious Diseases at Johns Hopkins University School of Medicine, Baltimore, said he was not surprised by the results. “CDC has been reporting increased incidence of Legionnaires’ disease from water source outbreaks over the years. As a clinician, I very much depend on epidemiologic trends to help me understand the patient in front of me.

“The key point is that there’s more of it around, so consider it in your diagnosis,” he advised.

“Physicians are increasingly beginning to consider Legionella. Because LD is difficult to diagnose by traditional methods such as culture, they may use a PCR test,” said Dr. Auwaerter, who was not involved in the study. “Legionella needs antibiotics that differ a bit from traditional antibiotics used to treat bacterial pneumonia, so a correct diagnosis can inform a more directed therapy.”

“Why the incidence is increasing is the big question, and the authors nicely outline a litany of things,” he said.

The authors and Dr. Auwaerter proposed a number of possible contributing factors to the increased incidence:

• an aging population
• aging municipal and residential water sources that may harbor more organisms
• racial disparities and poverty
• underlying conditions, including diabetes, end-stage renal disease, and some cancers
• occupations in transportation, repair, cleaning services, and construction
• weather patterns
• improved surveillance and reporting

“Why Legionella appears in some locations more than others has not been explained,” Dr. Auwaerter added. “For example, Pittsburgh always seemed to have much more Legionella than Baltimore.”

Mr. Barskey and his team are planning further research into racial disparities and links between weather and climate and Legionnaires’ disease.

The authors are employees of CDC. Dr. Auwaerter has disclosed no relevant financial realtionships.

Legionnaires’ disease (LD) in the United States appears to be on an upswing that started in 2003, according to a study from the Centers for Disease Control and Prevention.

The reasons for this increased incidence are unclear, the researchers write in Emerging Infectious Diseases.

“The findings revealed a rising national trend in cases, widening racial disparities between Black or African American persons and White persons, and an increasing geographic focus in the Middle Atlantic, the East North Central, and New England,” lead author Albert E. Barskey, MPH, an epidemiologist in CDC’s Division of Bacterial Diseases, Atlanta, said in an email.

“Legionnaires’ disease cannot be diagnosed based on clinical features alone, and studies estimate that it is underdiagnosed, perhaps by 50%,” he added. “Our findings may serve to heighten clinicians’ awareness of this severe pneumonia’s etiology, so with an earlier correct diagnosis, appropriate treatment can be rendered sooner.”

Mr. Barskey and his coauthors at CDC – mathematical statistician Gordana Derado, PhD, and epidemiologist Chris Edens, PhD – used surveillance data to investigate the incidence of LD in the U.S. over time. They compared LD incidence in 2018 with average incidence between 1992 and 2002. The incidence data, from over 80,000 LD cases, were age-standardized using the 2005 U.S. standard population as the reference.

The researchers analyzed LD data reported to CDC by the 50 states, New York City, and Washington, D.C., through the National Notifiable Diseases Surveillance System. They performed regression analysis to identify the optimal year when population parameters changed, and for most analyses, they compared 1992-2002 data with 2003-2018 data.

A New York state radiation oncologist accused of gross negligence and incompetence back in 2018 has now lost his medical license.

The state Board for Professional Medical Conduct has revoked the medical license of Won Sam Yi, MD, following a lengthy review of the care he provided to seven cancer patients; six of them died.

“He is a danger to potential new patients should he be reinstated as a radiation oncologist,” board members wrote, according to a news report in the Buffalo News.

Dr. Yi’s lawyer said that he is appealing the decision.

Dr. Yi was the former CEO of the now-defunct private cancer practice CCS Oncology, located in western New York.

In 2018, the state health department brought numerous charges of professional misconduct against Dr. Yi, including charges that he had failed to “account for prior doses of radiotherapy” as well as exceeding “appropriate tissue tolerances” during the treatment.

Now, the state’s Board for Professional Medical Conduct has upheld nearly all of the departmental charges that had been levied against him, and also found that Dr. Yi failed to take responsibility or show contrition for his treatment decisions.

However, whistleblower claims from a former CSS Oncology employee were dismissed.
 

Troubled history

CCS Oncology was once one of the largest private cancer practices in Erie and Niagara counties, both in the Buffalo metropolitan area.

Dr. Yi purchased CCS Oncology in 2008 and was its sole shareholder, and in 2012 he also acquired CCS Medical. As of 2016, the practices provided care to about 30% of cancer patients in the region. CCS also began acquiring other practices as it expanded into noncancer specialties, including primary care.

However, CCS began to struggle financially in late 2016, when health insurance provider Independent Health announced it was removing CCS Oncology from its network, and several vendors and lenders subsequently sued CCS and Dr. Yi for nonpayment.

The announcement from Independent Health was “financially devastating to CCS,” and also was “the direct cause” of the practice defaulting on its Bank of America loan and of the practice’s inability to pay not only its vendors but state and federal tax agencies, the Buffalo News reported. As a result, several vendors and lenders had sued CCS and Dr. Yi for nonpayment.

The FBI raided numerous CCS locations in March 2018, seizing financial and other data as part of an investigation into possible Medicare billing fraud. The following month, CCS filed for Chapter 11 bankruptcy, citing it owed millions of dollars to Bank of America and other creditors. Shortly afterward, the practice closed.
 

Medical misconduct

The state’s charges of professional misconduct accused Dr. Yi of “gross negligence,” “gross incompetence,” and several other cases of misconduct in treating seven patients between 2009 and 2013 at various CCS locations. The patients ranged in age from 27 to 72. Six of the seven patients died.

In one case, Dr. Yi was accused of providing whole-brain radiation therapy to a 43-year-old woman for about 6 weeks in 2012, but the treatment was “contrary to medical indications” and did not take into account prior doses of such treatment. The patient died in December of that year, and the board concluded that Dr. Yi had improperly treated her with a high dose of radiation that was intended to cure her cancer even though she was at a stage where her disease was incurable.

The state board eventually concluded that for all but one of the patients in question, Dr. Yi was guilty of misconduct in his treatment decisions. They wrote that Dr. Yi had frequently administered radiation doses without taking into account how much radiation therapy the patients had received previously and without considering the risk of serious complications for them.

Dr. Yi plans to appeal the board’s decision in state court, according to his attorney, Anthony Scher.

“Dr Yi has treated over 10,000 patients in his career,” Mr. Scher told the Buffalo News. “These handful of cases don’t represent the thousands of success stories that he’s had.”
