2019-2020 flu season starts off full throttle
For the week ending Nov. 23, there were five states, along with Puerto Rico, at the highest level of the Centers for Disease Control and Prevention’s 1-10 scale of flu activity. That’s more than any year since 2012, including the pandemic season of 2017-2018, according to CDC data, and may suggest either an early peak or the beginning of a particularly bad winter.
“Nationally, ILI [influenza-like illness] activity has been at or above baseline for 3 weeks; however, the amount of influenza activity across the country varies with the south and parts of the west seeing elevated activity while other parts of the country are still seeing low activity,” the CDC’s influenza division said in its weekly FluView report.
The five highest-activity states – Alabama, Georgia, Louisiana, Mississippi, and Texas – are all at level 10, and they join two others – South Carolina and Tennessee, which are at level 8 – in the “high” range from 8-10 on the ILI activity scale; Puerto Rico also is at level 10. ILI is defined as “fever (temperature of 100° F [37.8° C] or greater) and a cough and/or a sore throat without a known cause other than influenza,” the CDC said.
The activity scale is based on the percentage of outpatient visits for ILI in each state, which is reported to the CDC’s Outpatient Influenza-like Illness Surveillance Network (ILINet) each week. The national rate for the week ending Nov. 23 was 2.9%, which is above the new-for-this-season baseline rate of 2.4%. For the three previous flu seasons, the national baseline was 2.2%, having been raised from its previous level of 2.1% in 2015-2016, CDC data show.
The peak month of flu activity occurs most often in February – 15 times from 1982-1983 to 2017-2018 – but there were seven peaks in December and six each in January and March over that time period, along with one peak each in October and November, the CDC said. The October peak occurred during the H1N1 pandemic year of 2009, when the national outpatient ILI rate climbed to just over 7.7%.

FDA approves Oxbryta for sickle cell disease treatment
The Food and Drug Administration has approved voxelotor (Oxbryta) for adults and pediatric patients aged 12 years and older with sickle cell disease.
Approval was based on results from HOPE, a randomized, double-blind, placebo-controlled, multicenter trial of 274 patients with sickle cell disease (median age, 24 years) with a baseline hemoglobin level between 5.5 and 10.5 g/dL. Just over half of patients (51.1%) who received voxelotor at 1,500 mg had a hemoglobin increase of at least 1 g/dL over the 24-week study period, compared with 6.5% of patients who received placebo.
Patients in the 1,500-mg group also had reduced indirect bilirubin and percent reticulocyte count at –29.1% and –19.9%, respectively, compared with placebo, where the change was –3.2% and 4.5%, respectively.
The most common adverse events associated with voxelotor are headache, diarrhea, abdominal pain, nausea, rash, fatigue and pyrexia. The recommended voxelotor dose is 1,500 mg orally once daily with or without food, according to the FDA.

FDA: Two repackagers issue voluntary ranitidine recall
The ranitidine recall saga continues as two more companies have issued voluntary recalls of their repackaged ranitidine products because of possibly unacceptable levels of N-nitrosodimethylamine (NDMA), according to the Food and Drug Administration.
Golden State Medical Supply has recalled 150-mg and 300-mg ranitidine capsules, manufactured by Novitium, and Precision Dose has recalled a ranitidine oral solution at 150 mg/mL, manufactured by Amneal Pharmaceuticals.
“FDA has advised companies to recall their ranitidine if testing shows levels of NDMA above the acceptable daily intake (96 ng/day or 0.32 parts per million for ranitidine),” the FDA said. The agency has “posted the results of its testing of ranitidine samples and has asked companies to conduct their own laboratory testing.”
The FDA added that consumers taking over-the-counter ranitidine can consider alternatives such as famotidine (Pepcid), cimetidine (Tagamet), esomeprazole (Nexium), lansoprazole (Prevacid), and omeprazole (Prilosec).

FDA approves acalabrutinib for CLL, SLL treatment
The Food and Drug Administration has approved acalabrutinib (Calquence) as initial or subsequent treatment for adults with chronic lymphocytic leukemia (CLL) or small lymphocytic leukemia (SLL).
The approval came as part of Project Orbis, a collaboration among the FDA, the Australian Therapeutic Goods Administration, and Health Canada. The program allows for the concurrent submission of review of oncology drug applications among the various agencies.
Acalabrutinib, a bruton tyrosin kinase inhibitor, is already approved in the United States for the treatment of adults with mantle cell lymphoma who have received at least one prior therapy. The FDA granted breakthrough therapy designation to acalabrutinib as a monotherapy for adults with CLL in August 2019, allowing for an expedited review.
The approval in CLL/SLL was based on results from two randomized clinical trials comparing acalabrutinib with other standard treatments. In the first trial, patients with previously untreated CLL who received acalabrutinib had a longer progression-free survival time, compared with patients who received standard treatment. A similar result was seen in the second trial among patients with previously treated CLL.
The most common adverse events associated with acalabrutinib include anemia, neutropenia, upper respiratory tract infection, thrombocytopenia, headache, diarrhea, and musculoskeletal pain. Patients receiving the drug should be monitored for symptoms of arrhythmia, serious infection, bleeding, and low blood count. Full prescribing information can be found on the FDA website.

FDA approves Givlaari for treatment of acute hepatic porphyria
The Food and Drug Administration has approved givosiran (Givlaari) for the treatment of adult patients with acute hepatic porphyria, a genetic disorder that causes buildup of porphyrin molecules.
“This buildup can cause acute attacks, known as porphyria attacks, which can lead to severe pain and paralysis, respiratory failure, seizures, and mental status changes. These attacks occur suddenly and can produce permanent neurological damage and death. Prior to today’s approval, treatment options have only provided partial relief from the intense unremitting pain that characterizes these attacks,” Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence, said in a statement.
Approval for givosiran is based on results from a clinical trial of 94 patients with acute hepatic porphyria. Patients who received givosiran experienced 70% fewer porphyria attacks that required hospitalization, urgent health care visits, or home intravenous hemin injections compared with patients who received a placebo.
The most common adverse events associated with givosiran were nausea and injection site reactions. Patients receiving the medication should be monitored for anaphylactic reaction and renal function, and liver function should be tested before and periodically during treatment.
“The drug approved today can treat this disease by helping to reduce the number of attacks that disrupt the lives of patients,” said Dr. Pazdur, acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research.

Ask about vaping in patients with respiratory symptoms, CDC says
“Do you vape?” may be one of the most important questions health care can providers can ask patients who present with respiratory symptoms this winter.
according to the Centers for Disease Control and Prevention.
Accordingly, providers need to ask patients with respiratory, gastrointestinal, or constitutional symptoms about their use of e-cigarette or vaping products, according to one several new CDC recommendations that appear in the Morbidity and Mortality Weekly Review.
“E-cigarette or vaping product use–associated lung injury (EVALI) remains a diagnosis of exclusion because, at present, no specific test or marker exists for its diagnosis, and evaluation should be guided by clinical judgment,” the CDC report reads.
As of Nov. 13, there have been 2,172 cases of EVALI reported to CDC, of which 42 (1.9%) have been fatal. Most of the patients with EVALI have been white (79%), male (68%), and under the age of 35 years (77%), according to CDC data.
Although vitamin E acetate was recently implicated as a potential cause of EVALI, the agency said evidence is “not sufficient” at this point in their investigation to rule out other chemicals of potential concern.
“Many different substances and product sources are still under investigation, and it might be that there is more than one cause of this outbreak,” CDC said.
Further recommendations
Beyond asking about vape use, providers should evaluate suspected EVALI with pulse oximetry and chest imaging, and should consider outpatient management for patients who are clinically stable, according to the recommendations.
The agency said influenza testing should be “strongly considered,” especially during influenza season, given that EVALI is a diagnosis of exclusion and that it may co-occur with other respiratory illnesses. Antimicrobials (including antivirals) should be given as warranted, they added.
Corticosteroids may be helpful in treating EVALI, but may worsen respiratory infections typically seen in outpatients, and so should be prescribed with caution in the outpatient setting, the CDC recommended.
Behavioral counseling, addiction treatment services, and Food and Drug Administration–approved cessation medications are recommended to help patients quit vaping or e-cigarette products, CDC said.
Health care providers should emphasize the importance of an annual flu shot for all patients 6 months of age or older, including those who use e-cigarette or vaping products, according to the agency.
“It is not known whether patients with EVALI are at higher risk for severe complications of influenza or other respiratory infections,” the report reads.
Blame it on vitamin E? THC? Other?
The report details how, as previously reported, vitamin E acetate was detected in bronchoalveolar lavage fluid samples from 29 patients with EVALI. Although other chemicals could contribute to EVALI, that finding provided “direct evidence” of vitamin E acetate at the primary site of injury, according to CDC.
Most patients with EVALI, 83%, have reported using a tetrahydrocannabinol (THC)-containing e-cigarette or vaping product, according to CDC, while 61% reported using a nicotine-containing product.
Based on that, CDC recommended that people avoid using THC-containing products. However, the agency cautioned that the specific cause or causes of EVALI remain to be elucidated.
“The only way for persons to assure that they are not at risk is to consider refraining from use of all e-cigarette, or vaping, products while this investigation continues,” CDC said in the report.
The need for this additional clinical guidance was assessed in anticipation of the seasonal uptick in influenza and other respiratory infections, according to the CDC, which said the recommendations were based in part on individual clinical perspectives from nine national experts who participated in a previously published clinical guidance on managing patients with EVALI.

FDA announces approval of fifth adalimumab biosimilar, Abrilada
The Food and Drug Administration has cleared adalimumab-afzb (Abrilada) as the fifth approved Humira biosimilar and the 25th approved biosimilar drug overall, the agency said in a Nov. 15 announcement.
According to a press release from Pfizer, approval for Abrilada was based on review of a comprehensive data package demonstrating biosimilarity of the drug to the reference product. This included data from a clinical comparative study, which found no clinically meaningful difference between Abrilada and the reference in terms of efficacy, safety, and immunogenicity in patients with moderate to severe rheumatoid arthritis (RA). In addition to RA, Abrilada is indicated for juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult Crohn’s disease, ulcerative colitis, and plaque psoriasis.
Common adverse events in adalimumab clinical trials included infection, injection-site reactions, headache, and rash.
Pfizer said that it “is working to make Abrilada available to U.S. patients as soon as feasible based on the terms of our agreement with AbbVie [the manufacturer of Humira]. Our current plans are to launch in 2023.”
The Food and Drug Administration has cleared adalimumab-afzb (Abrilada) as the fifth approved Humira biosimilar and the 25th approved biosimilar drug overall, the agency said in a Nov. 15 announcement.
According to a press release from Pfizer, approval for Abrilada was based on review of a comprehensive data package demonstrating biosimilarity of the drug to the reference product.

FDA approves treatment for sickle cell pain crises
The Food and Drug Administration has approved crizanlizumab-tmca (Adakveo) to reduce the frequency of vaso-occlusive crisis, a common complication of sickle cell disease.
The drug is approved for patients aged 16 years and older. It was approved on the strength of the SUSTAIN trial, which randomized 198 patients with sickle cell disease and a history of vaso-occlusive crisis to crizanlizumab or placebo. Patients who received crizanlizumab had a median annual rate of 1.63 health care visits for vaso-occlusive crises, compared with patients who received placebo and had a median annual rate of 2.98 visits. The drug also delayed the first vaso-occlusive crisis after starting treatment from 1.4 months to 4.1 months, according to the FDA.
“Adakveo is the first targeted therapy approved for sickle cell disease, specifically inhibiting selectin, a substance that contributes to cells sticking together and leads to vaso-occlusive crisis,” Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence, said in a statement. “Vaso-occlusive crisis can be extremely painful and is a frequent reason for emergency department visits and hospitalization for patients with sickle cell disease.”
Common adverse events associated with crizanlizumab included back pain, nausea, pyrexia, and arthralgia. The FDA advised physicians to monitor patients for infusion-related reactions.

FDA approves Brukinsa for relapsed, refractory MCL
The Food and Drug Administration has approved zanubrutinib (Brukinsa) for the treatment of mantle cell lymphoma (MCL) in adult patients who have received at least one prior therapy.
The approval is based on results from two separate studies; in a global phase 1/2 trial, patients with relapsed or refractory MCL who received zanubrutinib had an overall response rate of 84%, with 22% experiencing a complete response and 62% experiencing partial response. Median duration of response was 18.5 months. The ORR in the second study – a multicenter phase 2 trial – was also 84%, but with 59% experiencing a complete response and 24% experiencing partial response; duration of response was 19.5 months.
The most common adverse events reported during the trials were decreased neutrophil count, decreased platelet count, upper respiratory tract infection, decreased white blood cell count, decreased hemoglobin, rash, bruising, diarrhea, cough, musculoskeletal pain, pneumonia, urinary tract infection, hematuria, fatigue, constipation, and hemorrhage. The most common serious adverse events were pneumonia and hemorrhage.
Of the 118 patients with MCL treated with zanubrutinib over the two trials, 8 had to be discontinued because of adverse events.
The recommended dose of zanubrutinib is 320 mg, taken orally 160 mg twice daily or 320 mg once daily, with or without food.
“BTK [Bruton kinase] inhibition is an established mode of treatment for patients with MCL, but many patients treated with previously approved BTK inhibitors do not fully respond to BTK therapy or are forced to discontinue treatment early due to side effects. Today we have a new option for our adult patients who have received one prior systemic or targeted therapy and are living with MCL,” Luhua (Michael) Wang, MD, clinical trial investigator and professor in the department of lymphoma and myeloma at the University of Texas MD Anderson Cancer Center, Houston, said in a statement.

FDA panel supports Vascepa expanded indication for CVD reduction
Icosapent ethyl, a highly purified form of the ethyl ester of eicosapentaenoic acid, received unanimous backing from a Food and Drug Administration advisory panel for a new indication for reducing cardiovascular event risk.
Icosapent ethyl (Vascepa) received initial agency approval in 2012 for the indication of cutting triglyceride levels once they reached at least 500 mg/dL.
The target patient population for this new, cardiovascular-event protection role will reflect some or all of the types of patients enrolled in REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial), which tested icosapent ethyl in 8,179 patients with either established cardiovascular disease or diabetes and at least one additional cardiovascular disease risk factor. This study provided the bulk of the data considered by the FDA panel.
REDUCE-IT showed that, during a median of 4.9 years, patients who received icosapent ethyl had a statistically significant 25% relative risk reduction in the trial’s primary, composite endpoint (New Engl J Med. 2019 Jan 3;380[1]:11-22).
Icosapent ethyl “appeared effective and safe,” and would be a “useful, new, added agent for treating patients” like those enrolled in the trial, said Kenneth D. Burman, MD, professor and chief of endocrinology at Medstar Washington (D.C.) Hospital Center and chair of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee.
The advisory panel members appeared uniformly comfortable with recommending that the FDA add a cardiovascular disease indication based on the REDUCE-IT findings.
But while they agreed that icosapent ethyl should receive some type of indication for cardiovascular event reduction, the committee split over which patients the indication should include. Specifically, they diverged on the issue of primary prevention.
Some said that the patient enrollment that produced a positive result in REDUCE-IT should not be retrospectively subdivided, while others said that combining secondary- and primary-prevention patients in a single large trial inappropriately lumped together patients who would be better considered separately.
Committee members also expressed uncertainty over the appropriate triglyceride level to warrant treatment. The REDUCE-IT trial was designed to enroll patients with triglycerides of 135 mg/dL or greater, but several panel members suggested that, for labeling, the threshold should be at least 150 mg/dL, or even 200 mg/dL.
Safety was another aspect that generated a lot of panel discussion throughout their day-long discussion, with particular focus on a signal of a small but concerning increased rate of incident atrial fibrillation among patients who received icosapent ethyl, as well as a small but nearly significant increase in the rate of serious bleeds.
Further analyses presented during the meeting showed that an increased bleeding rate linked with icosapent ethyl was focused in patients who concurrently received one or more antiplatelet drugs or an anticoagulant.
However, panel members rejected the notion that these safety concerns warranted a boxed warning, agreeing that it could be managed with appropriate labeling information.
Clinician reaction
Clinicians who manage these types of patients viewed the prospect of an expanded indication for icosapent ethyl as an important advance.
The REDUCE-IT results by themselves “were convincing” for patients with established cardiovascular disease without need for a confirmatory trial, Robert H. Eckel, MD, an endocrinologist and professor of medicine at the University of Colorado at Denver, Aurora, said in an interview. But he remained unconvinced about efficacy for primary-prevention patients, or even for secondary-prevention patients with a triglyceride level below 150 mg/dL.
“Icosapent ethyl will clearly be a mainstay for managing high-risk patients. It gives us another treatment option,” Yehuda Handelsman, MD, an endocrinologist and medical director and principal investigator of the Metabolic Institute of America in Tarzana, Calif., said in an interview. “I do not see the atrial fibrillation or bleeding effects as reasons not to approve this drug. It should be a precaution. Overall, icosapent ethyl is one of the easier drugs for patients to take.”
Dr. Handelsman said it would be unethical to run a confirmatory trial and randomize patients to placebo. “Another trial makes no sense,” he said.
But the data from REDUCE-IT were “not as convincing” for primary-prevention patients, suggesting a need for caution about using icosapent ethyl for patients without established cardiovascular disease, Paul S. Jellinger, MD, an endocrinologist in Fort Lauderdale, Fla., said in an interview.
Cost-effectiveness
An analysis of the cost-effectiveness of icosapent ethyl as used in REDUCE-IT showed that the drug fell into the rare category of being a “dominant” treatment, meaning that it both improved patient outcomes and reduced medical costs. William S. Weintraub, MD, will report findings from this analysis on Nov. 16, 2019, at the annual scientific sessions of the American Heart Association.
The analysis used a wholesale acquisition cost for a 1-day dosage of icosapent ethyl of $4.16, derived from a commercial source for prescription-drug pricing and actual hospitalization costs for the patients in the trial.
Based on the REDUCE-IT outcomes, treatment with icosapent ethyl was linked with a boost in quality-adjusted life-years that extrapolated to an average 0.26 increase during the full lifetime of REDUCE-IT participants, at a cost that averaged $1,284 less per treated patient over their lifetime, according to Dr. Weintraub, director of Outcomes Research at Medstar Washington Hospital Center, Washington.
Although the 0.26 lifetime increase in quality-adjusted life-years may sound modest, “in the cost-effectiveness world, 0.26 is actually significant,” Dr. Weintraub said. He also highlighted how unusual it is to find a patented drug that improves quality of life and longevity while also saving money.
“I know of no other on-patent, branded pharmaceutical that is dominant,” he said.
Off-patent pharmaceuticals, like statins, can be quite inexpensive and may also be dominant, he noted. Being dominant for cost-effectiveness means that icosapent ethyl “provides good value and is worth what we pay for it, well within social thresholds of willingness to pay,” Dr. Weintraub said.
REDUCE-IT was sponsored by Amarin, the company that markets icosapent ethyl (Vascepa). Dr. Burman has received research funding from AstraZeneca, Eisai, and IBSA. Dr. Eckel has received personal fees from Kowa Pharmaceuticals, Merck, Novartis, and Sanofi/Regeneron, as well as research funding from Endece, Ionis Pharmaceuticals, and UniQure. Dr. Handelsman has been a consultant to and received research funding from Amarin and several other companies. Dr. Jellinger has been a speaker on behalf of Amarin, Amgen, and Regeneron. Dr. Weintraub has received honoraria and research support from Amarin, and honoraria from AstraZeneca.
