Three JAK inhibitors get boxed warnings, modified indications
The arthritis and ulcerative colitis medicine tofacitinib (Xeljanz, Xeljanz XR) poses an increased risk of serious cardiac events such as heart attack or stroke, cancer, blood clots, and death, the Food and Drug Administration announced Sept 1.
Manufacturers of this drug along with other Janus kinase (JAK) inhibitors baricitinib (Olumiant) and upadacitinib (Rinvoq) must update their boxed warnings to include information about these health risks. The FDA made the determination after new study data from Pfizer, which manufacturers Xeljanz, found an association between a lower dose of Xeljanz and increased risk of blood clots and death.
“Recommendations for healthcare professionals will include consideration of the benefits and risks for the individual patient prior to initiating or continuing therapy,” the agency stated.
The FDA is limiting all approved uses of these three medications to patients who have not responded well to tumor necrosis factor (TNF) blockers to ensure their benefits outweigh their risks. Tofacitinib is indicated for rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. Baricitinib and upadacitinib are approved only for RA. The FDA included baricitinib and upadacitinib in the warning because of the similar properties they share with tofacitinib, even though they haven’t been studied as extensively.
“We believe this update will bring important clarity for healthcare plans on the risk/benefit profile of Xeljanz, which is a medicine informed by more clinical data than any other JAK inhibitor,” Pfizer said in a statement.
Investigators for the ORAL Surveillance trial compared two doses of tofacitinib (5 mg twice daily and 10 mg twice daily) with TNF blockers in patients with rheumatoid arthritis who were aged 50 years or older with at least one additional cardiovascular risk factor.
For both dose regimens of tofacitinib, they found an increased risk of major adverse cardiovascular events, malignancies, thrombosis, and death compared with the TNF blocker regimen. In addition, rates of lung cancers and lymphomas were higher with tofacitinib. In trial data released earlier this year, Pfizer revealed that the tofacitinib group had a much higher incidence of adjudicated malignancies compared with the TNF blocker group (1.13 vs. 0.77 per 100 person-years; hazard ratio, 1.48; 95% confidence interval, 1.04-2.09).
Impact on clinical practice
Physicians treating patients who have rheumatoid arthritis with tofacitinib may initially decrease prescriptions following the FDA’s drug safety communication, said Daniel E. Furst, MD, professor of medicine (emeritus) at the University of California, Los Angeles, adjunct professor at the University of Washington, Seattle, and a research professor at the University of Florence (Italy) – particularly those with a principal mechanism of action slightly different from that of tofacitinib, he added.
“Tofacitinib is principally a JAK 1,3 inhibitor at usual concentrations, whereas upadacitinib and baricitinib are JAK 1,2 inhibitors. Thus, I speculate that the tofacitinib prescriptions will go down more than the upadacitinib and baricitinib prescriptions,” he said in an interview.
Some patients may also be worried about taking tofacitinib, particularly those with previous events or predisposing conditions, Dr. Furst noted.
“First and foremost, I think we need to actually look at the data in a publication rather than just an FDA statement before making huge changes in our practice,” he advised.
“I am looking forward to the data finally being published ... It’s interesting that the full data still isn’t really out there beyond the press releases and an abstract. I think there’s a lot more to learn about how these drugs work and who is really at risk for harmful events,” said Alexis R. Ogdie, MD, MSCE, associate professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia.
Pfizer’s data also may be affecting FDA approvals of other JAK inhibitors. This past summer, AbbVie and Eli Lilly stated that the FDA’s ongoing assessment of the safety trial was delaying the agency’s decisions about expanding use of their respective drugs upadacitinib and baricitinib.
“I think many rheumatologists have already taken this information in, and begun to incorporate it into their discussions with their patients” since it has been over a year since the first public release of information about the ORAL Surveillance trial, said Arthur Kavanaugh, MD, professor of medicine at the University of California, San Diego. “I don’t know that it will affect the approvals, but it will impact their labels.”
Wariness to prescribing tofacitinib may be lower for patients younger than those in the ORAL Surveillance trial without additional cardiovascular risk factors who are taking tofacitinib for non-RA indications, said gastroenterologist Miguel Regueiro, MD.
“The JAK inhibitor warning by the FDA is an important consideration for any prescriber or patient. The risk of cardiovascular disease and venous thromboembolism with this class of medicine appears higher in older rheumatoid arthritis patients with underlying cardiovascular disease. While the warning applies to all JAK inhibitors and likely the newer selective JAK inhibitors to come, we need to weigh the risk and benefit based on the indication for prescribing,” said Dr. Regueiro, chair of the Digestive Disease and Surgery Institute and of the department of gastroenterology, hepatology and nutrition at the Cleveland Clinic in Ohio.
“I do think that there will be a heightened awareness and wariness for older RA patients and for the prescribers. However, for inflammatory bowel disease (and other non-RA indications), it does not appear that the risk for cardiovascular disease and VTE are significantly increased. To that end, in my own practice, I still use tofacitinib for ulcerative colitis and will do the same for the selective JAK inhibitors to come for IBD. Of course, as with any medication, we need to have discussions with our patients, alert them to potential side effects and have an open line of communication for any questions or concerns.”
Gastroenterologist Stephen Hanauer, MD, professor of medicine at Northwestern University, Chicago, thought that while patients with RA have many other treatment options besides JAK inhibitors, fewer options available to patients with IBD “may motivate the use of oral [sphingosine-1-phosphate receptor modulator] agents such as ozanimod, although IBD patients are younger and [have fewer] MACE risk factors than RA patients, so absolute risk is very small in the ulcerative colitis population.”
Pfizer’s data may be affecting FDA approvals of other JAK inhibitors. This past summer, AbbVie and Eli Lilly stated that the FDA’s ongoing assessment of the safety trial was delaying the agency’s decisions about expanding use of their respective drugs upadacitinib and baricitinib.
The agency’s decision corroborates an earlier 2019 warning about the increased risk of blood clots and of death in patients with ulcerative colitis taking 10 mg tofacitinib twice daily.
The FDA said that two other JAK inhibitors, ruxolitinib (Jakafi) and fedratinib (Inrebic), are not indicated for the treatment of arthritis and other inflammatory conditions, and so are not a part of the updates being required.
Baricitinib, abrocitinib, and upadacitinib are currently under FDA review for treating atopic dermatitis (AD); a topical formulation of the JAK1/2 inhibitor ruxolitinib is under review for treating AD. Reviews for all 4 have been extended. In September 2020, baricitinib was approved for treating moderate to severe AD in Europe, at a dose of 4 mg once a day, with recommendations that the dose can be reduced to 2 mg once a day when the disease is under control, and that the dose may need to be reduced in patients with impaired kidney function, those with an increased risk of infections, and those older than aged 75 years.
In an interview, Jacob Thyssen, MD, PhD, professor of dermatology at the University of Copenhagen, said that in the EU, there has been “extensive education” about cardiovascular risks with baricitinib “and it is my impression that payers and dermatologists in Europe are confident that it is safe to use in AD.” In addition, there has been an emphasis on the differences in cardiovascular risk factors between RA and AD patients, “given that the latter group is generally young and lean.” In the United States, he added, it will be interesting to see which doses of the JAK inhibitors will be approved for AD.
Dr. Thyssen disclosed that he is a speaker, advisory board member and/or investigator for Regeneron, Sanofi-Genzyme, Eli Lilly, Pfizer, LEO Pharma, AbbVie, and Almirall.

FDA approves first twice-yearly antipsychotic for schizophrenia
The U.S. Food and Drug Administration has approved a 6-month injection form of the long-acting atypical antipsychotic paliperidone palmitate (Invega Hafyera, Janssen Pharmaceuticals) for the treatment of schizophrenia in adults, the company has announced.
This marks the “first-and-only twice-yearly injectable” approved for treating schizophrenia, the company added in a press release.
Before transitioning to the 6-month form, patients must be adequately treated for a minimum of 4 months with the company’s 1-month formulation of paliperidone (Invega Sustenna), or with the 3-month version (Invega Trinza) for at least one 3-month injection cycle.
The FDA approved the twice-yearly formulation on the basis of results from a 12-month, randomized, double-blind, phase 3 study that enrolled 702 adults with schizophrenia from 20 countries.
“The phase 3 trial results provide compelling evidence that 6-month paliperidone palmitate offers longer-term symptom control with the fewest doses per year, which may support greater patient adherence,” Gustavo Alva, MD, medical director at ATP Clinical Research, Costa Mesa, Calif., and 6-month paliperidone palmitate clinical trial investigator, said in the release.
Noninferiority results
In the phase 3 trial, the twice-yearly version of the drug proved noninferior to the 3-month version on the primary endpoint of time to first relapse at the end of 12 months, with 92.5% and 95% of patients, respectively, relapse-free at 12 months.
Relapse was defined as psychiatric hospitalization, increase in Positive and Negative Syndrome Scale (PANSS) total score, increase in individual PANSS item scores, self-injury, violent behavior, or suicidal/homicidal ideation.
The safety profile observed in the trial was in line with prior studies of the 1-month and 3-month versions, with no new safety signals, the researchers note.
The most common adverse reactions affecting at least 5% of participants in the clinical trial receiving twice-year paliperidone were upper respiratory tract infection (12%), injection site reaction (11%), weight gain (9%), headache (7%), and parkinsonism (5%).
Relapse is common in adults with schizophrenia, often because of missed doses of medication, the company said in the news release.
, while research continues to demonstrate that stronger medication adherence means better patient outcomes,” Dr. Alva said.
Recently updated evidence-based guidelines from the American Psychiatric Association recommend consideration of long-acting injectables for appropriate adults living with schizophrenia.
“Long-acting injectable treatments offer a number of advantages, compared to oral medication for schizophrenia, including relief from needing to remember to take medication daily, lower discontinuation rates, and sustained treatment over longer periods,” Bill Martin, PhD, with Janssen Research & Development, said in the release.
“Today’s approval enables us to rethink how we manage this chronic disease by offering patients and caregivers the potential for a life less defined by schizophrenia medication,” Dr. Martin added.

FDA OKs IV Briviact for seizures in kids as young as 1 month
All three brivaracetam formulations (tablets, oral solution, and IV) may now be used. The approval marks the first time that the IV formulation will be available for children, the company said in a news release.
The medication is already approved in the United States as monotherapy and adjunctive therapy in adults with epilepsy.
In an open-label follow-up pediatric study, an estimated 71.4% of patients aged 1 month to 17 years with partial-onset seizures remained on brivaracetam therapy at 1 year, and 64.3% did so at 2 years, the company reported.
“We often see children with seizures hospitalized, so it’s important to have a therapy like Briviact IV that can offer rapid administration in an effective dose when needed and does not require titration,” Raman Sankar, MD, PhD, distinguished professor and chief of pediatric neurology, University of California, Los Angeles, said in the release.
“The availability of the oral dose forms also allows continuity of treatment when these young patients are transitioning from hospital to home,” he added.
Safety profile
Dr. Sankar noted that with approval now of both the IV and oral formulations for partial-onset seizures in such young children, “we have a new option that helps meet a critical need in pediatric epilepsy.”
The most common adverse reactions with brivaracetam include somnolence and sedation, dizziness, fatigue, nausea, and vomiting. In the pediatric clinical trials, the safety profile for pediatric patients was similar to adults.
In the adult trials, psychiatric adverse reactions, including nonpsychotic and psychotic symptoms, were reported in approximately 13% of adults taking at least 50 mg/day of brivaracetam compared with 8% taking placebo.
Psychiatric adverse reactions were also observed in open-label pediatric trials and were generally similar to those observed in adults.
Patients should be advised to report these symptoms immediately to a health care professional, the company noted.

FDA okays difelikefalin for dialysis-associated pruritus in patients with CKD
Some nephrologists welcomed the Aug. 23 approval of this new option for treating pruritus, a relatively common and often hard-to-resolve complication of dialysis in patients with chronic kidney disease (CKD) that can substantially impinge on quality of life for some patients, but also voiced uncertainty about the role of a new agent with a modest trial track record that may be expensive and face insurance-coverage hurdles.
“Uptake of difelikefalin will depend on awareness of itch among patients dependent on hemodialysis, and on payment policies,” predicted Daniel E. Weiner, MD, a nephrologist at Tufts Medical Center in Boston. “Pruritus is underdiagnosed among people with kidney failure, and in some patients ongoing pruritus can be highly impactful on sleep and quality of life. The clinical trial results were very encouraging that difelikefalin is effective and safe,” which makes recognition of pruritus as a significant issue for patients a key factor in uptake of the new drug, Dr. Weiner, an investigator in a difelikefalin clinical study, said in an interview.
Other nephrologists acknowledged the substantial problem that itch can pose for many patients with CKD on dialysis but questioned the weight of evidence behind difelikefalin’s approval.
Two pivotal trials with fewer than 900 total randomized patients
The data considered by the FDA primarily featured results from two pivotal trials, KALM-1 and KALM-2. KALM-1 randomized 378 patients with CKD and on hemodialysis and with moderate to severe pruritus to intravenous treatment with difelikefalin or placebo three times a week for 12 weeks with a primary endpoint of an improvement (decrease) of at least 3 points from baseline in their Worst Itching Intensity Numerical Rating Scale (WI-NRS) score, which averaged just over 7 points at baseline. After 12 weeks on treatment, 52% of patients who received difelikefalin had at least a 3-point drop, compared with 31% of patients who received placebo, a significant difference. The results appeared in a 2020 report in the New England Journal of Medicine.
Confirmatory results came in the second pivotal trial, KALM-2, a similarly designed, 12-week study that randomized 473 patients, with 54% of those in the active arm achieving at least a 3-point cut in their baseline WI-NRS score, compared with 42% of patients who received placebo, a significant difference. A report at the Kidney Week meeting sponsored by the National Kidney Foundation in October 2020 presented the KALM-2 results, but the findings have not yet appeared in a published article.
In sum, the data suggest that treatment with difelikefalin will, on average, produce a clinically meaningful effect on itch compared with placebo in about 20% of patients, with nearly half the patients who receive the active drug having a less robust response and many patients who receive no active treatment also show a meaningful cut in their pruritus severity in a trial setting, noted Paul Palevsky, MD, professor of medicine at the University of Pittsburgh and chief of the renal section at the Veterans Affairs Pittsburgh Healthcare System.
The upshot is that questions linger over which patients are the best candidates for this drug and how it might perform in real-world practice given difelikefalin’s limited track record, Dr. Palevsky said in an interview.
In addition, the labeling specifies the indication is for patients with moderate to severe pruritus, but itching severity is not routinely quantified in these patients in current practice, added Dr. Palevsky, who is also president of the National Kidney Foundation.
Dr. Weiner noted that another unknown is the appropriate duration of treatment in real-world use.
What will it cost, and will it be covered?
The drug’s price and insurance coverage will likely be a major factor in uptake of the new drug, agreed both Dr. Weiner and Dr. Palevsky, especially the coverage decision for Medicare patients by the Centers for Medicare & Medicaid Services. A corollary is whether or not coverage for difelikefalin, which patients receive as an intravenous infusion during each of their usual three-times-a-week dialysis sessions, will lie outside of the bundled dialysis reimbursement payment. If is no mechanism exists to pay for difelikefalin separately beyond the current bundled dialysis rate, “I suspect it will not get used very much unless it is very inexpensive,” predicted Dr. Weiner.
Another issue is where difelikefalin fits within the lineup of standard treatment options. “A lot of people receiving hemodialysis suffer from pruritus and have not been successfully treated. For these individuals difelikefalin could be a game changer,” Dr. Weiner said.
Other nephrologists have a more positive take on the existing treatment options.
“Start systemic therapy for patients with itch that is significantly affecting quality of life; stepping up from topical therapy just delays effective treatment,” advised Hugh C. Rayner, MD, a nephrologist affiliated with Birmingham (England) Heartland’s Hospital who was lead author on a review of pruritus treatments for patients with CKD on hemodialysis.
“Standard systemic therapy is gabapentin or pregabalin,” an approach “supported by robust evidence confirmed in a Cochrane review,” he said in an interview. The impact of difelikefalin “will be limited as its effectiveness in reducing itch is modest at best and far inferior to gabapentin and pregabalin,” Dr. Rayner added. Difelikefalin’s “main downsides will be its cost, compared with gabapentin, and its gastrointestinal side effects.”
Adverse-event profiles
In KALM-1, the most frequent adverse effects from difelikefalin treatment was diarrhea, in 10% of patients, compared with a 4% rate among patients who received placebo. Vomiting occurred at a 5% incidence on difelikefalin and in 3% of patients on placebo. All serious adverse events occurred in 26% of patients on difelikefalin and in 22% of those who received placebo. Discontinuations because of an adverse event occurred in 8% of patients on difelikefalin and in 5% of the placebo patients.
An editorial that accompanied the published KALM-1 report in 2020 said “the findings are compelling, although diarrhea, dizziness, and vomiting were frequent side effects.”
Both Dr. Weiner and Dr. Palevsky were more reserved than Dr. Rayner in their appraisal of gabapentin and pregabalin, although Dr. Palevsky admitted that he has prescribed one or the other of these two drugs to “lots of patients,” especially gabapentin. “But they are not completely benign drugs,” he cautioned, a concern echoed by Dr. Weiner.
“Antihistamines, gabapentin, and pregabalin have a high side-effect burden in patients on hemodialysis and limited efficacy, and are poor options for chronic pruritus management,” explained Dr. Weiner. “I would favor difelikefalin to chronic prescription of these other agents” because difelikefalin “appears effective and has a very low side effect burden. Very few effective treatments for pruritus do not have side effects.”
Difelikefalin is a peripherally restricted, selective kappa opioid receptor agonist that exerts antipruritic effects by activating kappa opioid receptors on peripheral neurons and immune cells. The drug’s hydrophilic, small-peptide structure restricts passive diffusion across membranes, which limits the drug’s access to kappa opioid receptors in the central nervous system and hence reduces potential adverse effects.
The FDA made this approval decision without consulting an advisory committee. The companies that will market difelikefalin (Korsuva), Cara Therapeutics and Vifor Pharma, announced that their U.S. promotional launch of the drug starts early in 2022.
The KALM-1 and KALM-2 studies were sponsored by Cara Therapeutics and Vifor Pharma, the two companies that have been jointly developing difelikefalin. Dr. Pavelsky and Dr. Rayner had no relevant disclosures. Dr. Weiner was previously an adviser to Cara and Vifor and participated as an investigator in a difelikefalin clinical study, but more recently has had no relationships with the companies.

Bimekizumab approved in Europe for psoriasis treatment
, according to a statement from the manufacturer.
Bimekizumab (Bimzelx), a humanized IgG1 monoclonal antibody, is the first approved treatment for moderate to severe plaque psoriasis that selectively inhibits interleukin (IL)–17A and IL-17F, the statement from UCB said.
In the United States, the Food and Drug Administration is expected to make a decision on approval of bimekizumab for treating psoriasis on Oct. 15.
Approval in the EU was based on data from three phase 3 trials including a total of 1,480 adult patients with moderate to severe psoriasis, which found that those treated with bimekizumab experienced significantly greater skin clearance, compared with placebo, ustekinumab, and adalimumab, with a favorable safety profile, according to the company.
In all three studies (BE VIVID, BE READY, and BE SURE), more than 80% of patients treated with bimekizumab showed improved skin clearance after 16 weeks, significantly more than those treated with ustekinumab, placebo, or adalimumab, based on an improvement of at least 90% in the Psoriasis Area & Severity Index (PASI 90) and an Investigator’s Global Assessment (IGA) response of clear or almost clear skin (IGA 0/1). In all three studies, these clinical responses persisted after 1 year.
The recommended dose of bimekizumab is 320 mg, given in two subcutaneous injections every 4 weeks to week 16, then every 8 weeks. However, for “some patients” weighing 120 kg or more who have not achieved complete skin clearance at 16 weeks, 320 mg every 4 weeks after that time may improve response to treatment, according to the company statement.
The most common treatment-related adverse events in the studies were upper respiratory tract infections (a majority of which were nasopharyngitis), reported by 14.5% of patients, followed by oral candidiasis, reported by 7.3%.
Results of BE READY and BE VIVID were published in The Lancet. Results of the BE SURE study were published in The New England Journal of Medicine.
Bimekizumab is contraindicated for individuals with clinically important active infections such as tuberculosis, and for individuals with any hypersensitivity to the active substance. More details on bimekizumab are available on the website of the European Medicines Agency.

The recommended dose of bimekizumab is 320 mg, given in two subcutaneous injections every 4 weeks to week 16, then every 8 weeks. However, for “some patients” weighing 120 kg or more who have not achieved complete skin clearance at 16 weeks, 320 mg every 4 weeks after that time may improve response to treatment, according to the company statement.
The most common treatment-related adverse events in the studies were upper respiratory tract infections (a majority of which were nasopharyngitis), reported by 14.5% of patients, followed by oral candidiasis, reported by 7.3%.
Results of BE READY and BE VIVID were published in The Lancet. Results of the BE SURE study were published in The New England Journal of Medicine.
Bimekizumab is contraindicated for individuals with clinically important active infections such as tuberculosis, and for individuals with any hypersensitivity to the active substance. More details on bimekizumab are available on the website of the European Medicines Agency.
Empagliflozin gets HFrEF approval from FDA
The U.S. Food and Drug Administration approved empagliflozin (Jardiance) as a treatment for adults with heart failure with reduced ejection fraction (HFrEF) regardless of whether patients have diabetes on Aug. 18, making it the second agent from the sodium-glucose transporter 2 inhibitor class to received this indication.
Empagliflozin first received FDA marketing approval in 2014 for improving glycemic control in patients with type 2 diabetes, and in 2016 the agency added a second indication of reducing cardiovascular death in patients with type 2 diabetes and cardiovascular disease. The newly granted indication for patients with HFrEF without regard to glycemic status was for reducing the risk for cardiovascular death and hospitalization for heart failure, according to a statement from Boehringer Ingelheim and Lilly, the two companies that together market empagliflozin.
The statement also said that the approval allowed for empagliflozin treatment in patients with HFrEF and an estimated glomerular filtration rate (eGFR) as low as 20 mL/min per 1.73 m2, in contrast to its indication for improving glycemic control in patients with type 2 diabetes that limits use to patients with an eGFR of at least 30 mL per 1.73 m2.
EMPEROR-Reduced results drive approval
The FDA based its decision on results from the EMPEROR-Reduced study, first reported in August 2020, that showed treatment of patients with HFrEF with empagliflozin on top of standard therapy for a median of 16 months cut the incidence of cardiovascular death or hospitalization for worsening heart failure by 25% relative to placebo, and by an absolute 5.3%, compared with placebo-treated patients.
Patients enrolled in EMPEROR-Reduced had chronic heart failure in New York Heart Association functional class II-IV and with a left ventricular ejection fraction of 40% or less, the standard ejection fraction criterion for defining HFrEF. Half the enrolled patients had diabetes, and analysis showed no heterogeneity in the primary outcome response based on diabetes status at enrollment.
Empagliflozin joins dapagliflozin for treating HFrEF
Dapagliflozin (Farxiga) was the first agent from the SGLT2 inhibitor class to receive an FDA indication, in 2020, for treating patients with HFrEF regardless of their diabetes status, a decision based on results from the DAPA-HF trial. Results from DAPA-HF showed that treatment with dapagliflozin in patients with HFrEF for a median of 18 months led to a 26% relative reduction in the incidence of cardiovascular death or worsening heart failure and a 4.9% absolute reduction, compared with placebo when added to standard treatment. DAPA-HF enrolled patients using similar criteria to EMPEROR-Reduced, and 42% of enrolled patients had diabetes with no heterogeneity in the primary outcome related to baseline diabetes status.
Subsequent to the report of results from the EMPEROR-Reduced trial nearly a year ago, heart failure experts declared that treatment with an agent from the SGLT2 inhibitor class had become a “new pillar of foundational therapy for HFrEF,” and they urged rapid initiation of an SGLT2 inhibitor (along with other appropriate medications) at the time of initial diagnosis of HFrEF.

FDA OKs stimulation device for anxiety in depression
The U.S. Food and Drug Administration has expanded the indication for the noninvasive BrainsWay Deep Transcranial Magnetic Stimulation (Deep TMS) System to include treatment of comorbid anxiety symptoms in adult patients with depression, the company has announced.
As reported by this news organization, the neurostimulation system has previously received FDA approval for treatment-resistant major depression, obsessive-compulsive disorder, and smoking addiction.
In the August 18 announcement, BrainsWay reported that it has also received 510(k) clearance from the FDA to market its TMS system for the reduction of anxious depression symptoms.
“This clearance is confirmation of what many have believed anecdotally for years – that Deep TMS is a unique form of therapy that can address comorbid anxiety symptoms using the same depression treatment protocol,” Aron Tendler, MD, chief medical officer at BrainsWay, said in a press release.
‘Consistent, robust’ effect
, which included both randomized controlled trials and open-label studies.
“The data demonstrated a treatment effect that was consistent, robust, and clinically meaningful for decreasing anxiety symptoms in adult patients suffering from major depressive disorder [MDD],” the company said in its release.
Data from three of the randomized trials showed an effect size of 0.3 when compared with a sham device and an effect size of 0.9 when compared with medication. The overall, weighted, pooled effect size was 0.55.
The company noted that in more than 70 published studies with about 16,000 total participants, effect sizes have ranged from 0.2-0.37 for drug-based anxiety treatments.
“The expanded FDA labeling now allows BrainsWay to market its Deep TMS System for the treatment of depressive episodes and for decreasing anxiety symptoms for those who may exhibit comorbid anxiety symptoms in adult patients suffering from [MDD] and who failed to achieve satisfactory improvement from previous antidepressant medication treatment in the current episode,” the company said.

FDA approves Pfizer’s tick-borne encephalitis vaccine
The U.S. Food and Drug Administration has approved Pfizer’s TicoVac vaccine for the treatment of tick-borne encephalitis (TBE). The vaccine is approved outside of the United States, and more than 170 million doses have been administered since 1976. The World Health Organization recommends vaccination for everyone in areas where the annual incidence of clinical disease is highly endemic, defined as more than five cases per 100,000 population, which is primarily the Baltic countries of Europe but includes some regions of Central and East Asia.
GlaxoSmithKline’s Encepur is also approved outside the United States, as is a vaccine from China and two from Russia. The efficacy of all the vaccines is greater than 95%. Pfizer’s protection is 98.7% to 100.0% after the three-dose course. With the new approval, American travelers will be able to get immunized before their departure instead of waiting until they are overseas to start the series.
TicoVac can cause injection-site pain, headache, myalgia, and fever, as is typical with many vaccines.
Tick-borne encephalitis
TBE is caused by a flavivirus and is transmitted by the bite of an infected Ixodes scapularis, or deer tick. Like the Powassan virus, another flavivirus, infection can be transmitted in minutes through the tick’s saliva, so early removal of the tick might not prevent illness. This is different than Lyme disease, where vigilance and early removal of the tick can prevent transmission.
Reservoirs for the virus include mice, voles, and shrews. Large mammals (deer, sheep, cattle, goats) also serve to support tick multiplication. In addition to tick bites, ingestion of unpasteurized milk from infected mammals can transmit TBE.
TBE symptoms can range from none to severe encephalitis (brain inflammation). One-quarter of infected people develop encephalitis. Most recover fully, but one-third of those infected can develop lifelong damage and paralysis or cognitive deficits. Death is rare, except in those infected with the Russian strain.
The first phase of a TBE infection is typical of viral infections, with nonspecific fever, headache, nausea, and myalgia. The next phase involves an asymptomatic interval of about a week (range, 1 to 33 days), followed by symptoms of a central nervous system infection.
There is no treatment for TBE and no antivirals with proven benefit. However, a recent case report describes the successful treatment of TBE with favipiravir.
For now, if you are unvaccinated, prevention is the only viable option. If you plan to travel to an endemic region and anticipate participating in outdoor activities (such as hunting or hiking), wear permethrin-treated clothes, use an insecticide, and don’t eat or drink unpasteurized dairy products.

FDA approves Abbott’s Amplatzer Amulet for AFib
The Food and Drug Administration has approved the Amplatzer Amulet left atrial appendage occluder (Abbott) to treat people with nonvalvular atrial fibrillation who are at increased risk for stroke and systemic embolism.
The Amulet and its competitor, Boston Scientific’s Watchman, are minimally invasive devices used to close off the left atrial appendage (LAA), an area where blood clots tend to form in people with atrial fibrillation.
Amulet uses dual-seal technology to completely and immediately seal the LAA, the company says, whereas the other minimally invasive solution uses a single component to seal the LAA that requires blood-thinning drugs to heal and additional patient monitoring. The Amulet also has the widest range of occluder sizes on the market and is recapturable and repositionable to ensure optimal placement.
“As the world’s population continues to age, we’re seeing a surge in atrial fibrillation cases, and with that comes increased risk of stroke. The approval of Abbott’s Amulet device provides physicians with a treatment option that reduces the risk of stroke and eliminates the need for blood-thinning medication immediately after the procedure, which is incredibly valuable given the bleeding risks associated with these medicines,” Dhanunjaya Lakkireddy, MD, Kansas City Heart Rhythm Institute at HCA Midwest Health, Overland Park, Kan., and principal investigator for the study that led to FDA approval, said in a news release from Abbott.
The FDA approval is supported by findings from the global Amulet IDE trial, a head-to-head comparison of the Amulet and Watchman devices in 1,878 participants with nonvalvular atrial fibrillation. The results will be presented virtually on Aug. 30 at the 2021 annual congress of the European Society of Cardiology.
The Amplatzer Amulet received CE Mark designation in 2013 and is approved for use in more than 80 countries, including in Australia, Canada, and European countries.

FDA approves rapid-acting insulin, Lyumjev, for pump use
The Food and Drug Administration has expanded the label for Eli Lilly’s ultra–rapid-acting insulin lispro-aabc injection 100 units/mL (Lyumjev) for use in insulin pumps.
Lyumjev (insulin lispro-aabc injection 100 and 200 units/mL) was initially approved in June 2020 to improve glycemic control in adults with type 1 or type 2 diabetes. That formulation is administered by injection from a pen or syringe. Now, the 100 units/mL formulation can also be delivered via continuous subcutaneous insulin infusion with an insulin pump.
Lyumjev will compete with Novo Nordisk’s fast-acting insulin aspart injection 100 units/mL (Fiasp). Fiasp had a head start: it was approved for use in adults in the United States in September 2017. It was approved for use in insulin pumps in October 2019 and for use in children with diabetes in January 2020.
The new approval for Lyumjev was based on data from a phase 3 trial, PRONTO-Pump-2. That trial, which included 432 participants with type 1 diabetes, confirmed the drug’s safety and efficacy when used in pumps.
The study met the primary endpoint of noninferiority in reduction of hemoglobin A1c from baseline to week 16, compared with insulin lispro (Humalog 100 units/mL). It was superior in both 1-hour and 2-hour postprandial glucose reduction when delivered 0-2 minutes before meals, according to a Lilly statement.
Patients who cannot afford the drug can go to www.insulinaffordability.com for assistance. Those with commercial insurance can also visit www.Lyumjev.com to access the Lyumjev Savings Card.
Lyumjev is available in several global markets, including Japan and the European Union, where it is also approved for use in insulin pumps.

The Food and Drug Administration has expanded the label for Eli Lilly’s ultra–rapid-acting insulin lispro-aabc injection 100 units/mL (Lyumjev) for use in insulin pumps.
Lyumjev (insulin lispro-aabc injection 100 and 200 units/mL) was initially approved in June 2020 to improve glycemic control in adults with type 1 or type 2 diabetes. That formulation is administered by injection from a pen or syringe. Now, the 100 units/mL formulation can also be delivered via continuous subcutaneous insulin infusion with an insulin pump.
Lyumjev will compete with Novo Nordisk’s fast-acting insulin aspart injection 100 units/mL (Fiasp). Fiasp had a head start: it was approved for use in adults in the United States in September 2017. It was approved for use in insulin pumps in October 2019 and for use in children with diabetes in January 2020.
The new approval for Lyumjev was based on data from a phase 3 trial, PRONTO-Pump-2. That trial, which included 432 participants with type 1 diabetes, confirmed the drug’s safety and efficacy when used in pumps.
