FDA approves ninth Humira biosimilar, with interchangeability
The Food and Drug Administration has granted an interchangeability designation to adalimumab-afzb (Abrilada), according to an announcement from Pfizer.
This is the second adalimumab biosimilar granted interchangeability. The first, adalimumab-adbm (Cyltezo), became available in July.
Biosimilars introduce market competition that can help lower drug prices. Adalimumab-afzb is one of nine approved biosimilars for Humira, and the last to launch in 2023.
Adalimumab-afzb is indicated for:
- Adults with rheumatoid arthritis.
- Polyarticular juvenile idiopathic arthritis in patients 2 years of age and older.
- Adults with psoriatic arthritis.
- Adults with ankylosing spondylitis.
- Crohn’s disease in adults and children 6 years of age and older.
- Adults with ulcerative colitis.
- Adults with plaque psoriasis.
- Adults with hidradenitis suppurativa.
- Adults with noninfectious intermediate and posterior uveitis and panuveitis.
“With this designation, Abrilada is now both biosimilar to and interchangeable with Humira, reinforcing confidence among physicians and pharmacists that there is no decrease in effectiveness or increase in safety risk associated with switching between Abrilada and the reference product,” Roy Fleischmann, MD, clinical professor of medicine, University of Texas Southwestern Medical Center, Dallas, said in Pfizer’s statement.
An interchangeability designation allows pharmacists to substitute the biosimilar for the reference product without involving the prescribing clinician (according to state law). To achieve this designation, Pfizer submitted data from a phase 3 study led by Dr. Fleischmann that evaluated adalimumab-afzb in patients with RA. Patients who were switched three times between the biosimilar and the reference product had outcomes similar to those of patients continuously treated with the reference product.
Adalimumab-afzb will be available later in October at a 5% discount from Humira’s price. Later this year, the drug will launch at a second price, a 60% discount from Humira.

FDA approves first tocilizumab biosimilar
The Food and Drug Administration has approved the biosimilar tocilizumab-bavi (Tofidence), Biogen, the drug’s manufacturer, announced on Sept. 29.
It is the first tocilizumab biosimilar approved by the FDA. The reference product, Actemra (Genentech), was first approved by the agency in 2010.
“The approval of Tofidence in the U.S. marks another positive step toward helping more people with chronic autoimmune conditions gain access to leading therapies,” Ian Henshaw, global head of biosimilars at Biogen, said in a statement. “With the increasing numbers of approved biosimilars, we expect increased savings and sustainability for health care systems and an increase in physician choice and patient access to biologics.”
Biogen’s pricing for tocilizumab-bavi will be available closer to the product’s launch date, which has yet to be determined, a company spokesman said. The U.S. average monthly cost of Actemra for rheumatoid arthritis, administered intravenously, is $2,134-$4,268 depending on dosage, according to a Genentech spokesperson.
Tocilizumab-bavi is an intravenous formulation (20 mg/mL) indicated for treatment of moderately to severely active RA, polyarticular juvenile idiopathic arthritis (PJIA), and systemic juvenile idiopathic arthritis (SJIA). The medication is administered every 4 weeks in RA and PJIA and every 8 weeks in SJIA as a single intravenous drip infusion over 1 hour.
The European Commission approved its first tocilizumab biosimilar, Tyenne (Fresenius Kabi), earlier in 2023 in both subcutaneous and intravenous formulations. Biogen did not comment on whether the company is working on a subcutaneous formulation for tocilizumab-bavi.

FDA issues letter regarding lebrikizumab review for atopic dermatitis
The Food and Drug Administration has issued a complete response letter regarding lebrikizumab, an investigational biologic for the treatment of adult and adolescent patients with moderate to severe atopic dermatitis, describing concerns about findings made during an inspection of a third-party contract manufacturer that included the “monoclonal antibody drug substance” for lebrikizumab, Eli Lilly announced in an Oct. 2 press release.
Lebrikizumab is under FDA review for treating atopic dermatitis; a complete response letter indicates that the review has been completed, and highlights issues that need to be addressed before a final decision on approval is made.
The press release noted that the agency did not raise any concerns about the clinical data package, safety, or label for lebrikizumab, an investigational, monoclonal antibody that binds to the cytokine interleukin (IL)-13, and is designed to be administered once per month.
In the press release, the company said it would work with the third-party manufacturer and the FDA to address the feedback “in order to make lebrikizumab available to patients.”

FDA OKs subcutaneous vedolizumab for UC maintenance therapy
The Food and Drug Administration has approved the subcutaneous administration of vedolizumab (Entyvio SC, Takeda) for maintenance therapy in adults with moderately to severely active ulcerative colitis (UC) following induction therapy with intravenous administration of vedolizumab.
The FDA approved the intravenous formulation of the biologic in 2014 for patients with moderate to severe UC and Crohn’s disease who failed or cannot tolerate other therapies.
The approval of subcutaneous (SC) vedolizumab was based on results from the phase 3, randomized, double-blind, placebo-controlled VISIBLE 1 trial.
The trial assessed the safety and efficacy of maintenance therapy with SC vedolizumab in adult patients with moderately to severely active UC who achieved clinical response at week 6 following two doses of intravenous vedolizumab.
At week 6, 162 patients were randomly allocated (2:1) to vedolizumab or placebo by subcutaneous injection every 2 weeks. The primary endpoint was clinical remission at week 52, defined as a total Mayo score of 2 or less and no individual subscore greater than 1.
At week 52, nearly half (46%) of patients who received vedolizumab SC maintenance therapy achieved clinical remission, compared with 14% of those who received placebo SC (P < .001).
The safety profile of SC vedolizumab was “generally consistent” with that of intravenous vedolizumab, with the addition of injection-site reactions, the drugmaker, Takeda, said in a news release.
The most common adverse reactions with intravenous vedolizumab are nasopharyngitis, headache, arthralgia, nausea, pyrexia (fever), upper respiratory tract infection, fatigue, cough, bronchitis, influenza, back pain, rash, pruritus, sinusitis, oropharyngeal pain, and pain in the extremities.
SC vedolizumab “can provide physicians with an additional administration option for achieving remission in their moderate to severe ulcerative colitis patients,” according to Bruce E. Sands, MD, AGAF, chief of gastroenterology at the Icahn School of Medicine at Mount Sinai, New York. He provided a statement in the Takeda news release.
“I appreciate now having a subcutaneous administration option that provides a clinical profile consistent with Entyvio intravenous while also giving me and my appropriate UC patients a choice of how they receive their maintenance therapy,” Dr. Sands said.
The FDA is currently reviewing Takeda’s biologics license application for subcutaneous administration of vedolizumab in the treatment of adults with moderately to severely active Crohn’s disease.
Dr. Sands is a paid consultant of Takeda.

FDA approves bosutinib for children with CML
The agency also approved new 50-mg and 100-mg capsules to help treat children.
For newly diagnosed disease, the dose is 300 mg/m2 once daily with food. For resistant/intolerant disease, the dose is 400 mg/m2 once daily. For children who cannot swallow capsules, the contents can be mixed into applesauce or yogurt, the FDA said in a press release announcing the approval.
The tyrosine kinase inhibitor (TKI) was previously approved for adults. Three other TKIs were previously approved for pediatric CML.
The approval was based on the BCHILD trial, a pediatric dose-finding study involving patients aged 1 year or older. Among the 21 children with newly diagnosed chronic phase, Ph+ CML treated with 300 mg/m2, the rate of major cytogenetic response was 76.2%, the rate of complete cytogenetic response was 71.4%, and the rate of major molecular response rate was 28.6% over a median duration of 14.2 months.
Among the 28 children with relapsed/intolerant disease treated with up to 400 mg/m2, the rate of major cytogenetic response was 82.1%, the rate of complete cytogenetic response was 78.6%, and the rate of major molecular response was 50% over a median duration of 23.2 months. Among the 14 patients who had a major molecular response, two lost it – one after 13.6 months of treatment, and the other after 24.7 months of treatment.
Adverse events that occurred in 20% or more of children included diarrhea, abdominal pain, vomiting, nausea, rash, fatigue, hepatic dysfunction, headache, pyrexia, decreased appetite, and constipation. Overall, 45% or more of patients experienced an increase in creatinine, alanine aminotransferase, or aspartate aminotransferase levels, or a decrease in white blood cell count or platelet count.

FDA approves JAK inhibitor momelotinib for myelofibrosis with anemia
Momelotinib is the fourth JAK inhibitor to be approved by the agency for myelofibrosis but the only one indicated for patients with hemoglobin levels below 10 g/dL.
It’s an important development because, while JAK inhibitors are standard treatment for myelofibrosis, those previously approved for the uncommon blood cancer can cause cytopenia, particularly anemia, which, ironically, is also a hallmark of myelofibrosis itself.
This issue makes using JAK inhibitors for myelofibrosis challenging, according to Anthony Hunter, MD, a myeloid malignancies specialist at Emory University, Atlanta, who spoke on the topic recently at the annual meeting of the Society of Hematologic Oncology in Houston. “Momelotinib is an important emerging agent for these more anemic patients.” Momelotinib has a spleen response comparable with ruxolitinib – the first JAK inhibitor approved for myelofibrosis in the United States – and significantly higher rates of transfusion independence, although lower rates of symptom control, he said.
In GSK’s press release, hematologist/oncologist Ruben Mesa, MD, executive director of Atrium Health Wake Forest Baptist Comprehensive Cancer Center, Winston-Salem, N.C., said that, “with momelotinib, we have the potential to establish a new standard of care for myelofibrosis patients with anemia.”
Momelotinib’s specific indication is for “the treatment of intermediate or high-risk myelofibrosis, including primary myelofibrosis or secondary myelofibrosis (post–polycythemia vera and post–essential thrombocythemia), in adults with anemia.”
The once-daily oral medication was approved based on two trials. One trial, MOMENTUM, showed statistically significant response with respect to constitutional symptoms, splenic response, and transfusion independence in anemic patients treated with momelotinib versus danazol.
An anemic subset of the SIMPLIFY-1 trial showed comparable spleen volume reduction versus ruxolitinib but a numerically lower symptom response rate.
The most common momelotinib adverse reactions in trials were thrombocytopenia, hemorrhage, bacterial infection, fatigue, dizziness, diarrhea, and nausea.

Submission of the sNDA is based on positive results from the Interventional Trial Evaluating Roflumilast Cream for the Treatment of Atopic Dermatitis (INTEGUMENT-1 and INTEGUMENT-2) trials; two identical Phase 3, vehicle-controlled trials in which roflumilast cream 0.15% or vehicle was applied once daily for 4 weeks to individuals 6 years of age and older with mild to moderate AD involving at least 3% body surface area. Roflumilast is a phosphodiesterase-4 (PDE-4) inhibitor.
According to a press release from Arcutis, both studies met the primary endpoint of IGA Success, which was defined as a validated Investigator Global Assessment – Atopic Dermatitis (vIGA-AD) score of ‘clear’ or ‘almost clear’ plus a 2-grade improvement from baseline at week 4. In INTEGUMENT-1 this endpoint was achieved by 32.0% of subjects in the roflumilast cream group vs. 15.2% of those in the vehicle group (P < .0001). In INTEGUMENT-2, this endpoint was achieved by 28.9% of subjects in the roflumilast cream group vs. 12.0% of those in the vehicle group (P < .0001). The most common adverse reactions based on data from the combined trials were headache (2.9%), nausea (1.9%), application-site pain (1.5%), diarrhea (1.5%), and vomiting (1.5%).

New COVID vaccines force bivalents out
COVID vaccines will have a new formulation in 2023, according to a decision announced by the U.S. Food and Drug Administration, that will focus efforts on circulating variants. The move pushes last year’s bivalent vaccines out of circulation because they will no longer be authorized for use in the United States.
The updated mRNA vaccines for 2023-2024 are being revised to include a single component that corresponds to the Omicron variant XBB.1.5. Like the bivalents offered before, the new monovalents are being manufactured by Moderna and Pfizer.
The new vaccines are authorized for use in individuals age 6 months and older. And the new options are being developed using a similar process as previous formulations, according to the FDA.
Targeting circulating variants
In recent studies, regulators point out the extent of neutralization observed by the updated vaccines against currently circulating viral variants causing COVID-19, including EG.5, BA.2.86, appears to be of a similar magnitude to the extent of neutralization observed with previous versions of the vaccines against corresponding prior variants.
“This suggests that the vaccines are a good match for protecting against the currently circulating COVID-19 variants,” according to the report.
Hundreds of millions of people in the United States have already received previously approved mRNA COVID vaccines, according to regulators who say the benefit-to-risk profile is well understood as they move forward with new formulations.
“Vaccination remains critical to public health and continued protection against serious consequences of COVID-19, including hospitalization and death,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said in a statement. “The public can be assured that these updated vaccines have met the agency’s rigorous scientific standards for safety, effectiveness, and manufacturing quality. We very much encourage those who are eligible to consider getting vaccinated.”
Timing the effort
On Sept. 12 the U.S. Centers for Disease Control and Prevention recommended that everyone 6 months and older get an updated COVID-19 vaccine. Updated vaccines from Pfizer-BioNTech and Moderna will be available later this week, according to the agency.

FDA approves motixafortide for stem cell mobilization in myeloma
The success of autologous stem cell transplantation (ASCT) depends on adequate mobilization of stem cells during the treatment process. Collection of a sufficient number of stem cells to perform two transplantations is recommended. However, in up to 47% of patients, collecting target numbers of hematopoietic stem cells for ASCT after one apheresis session remains a challenge, BioLineRx explained in a press release today, announcing the approval.
The goal of combining motixafortide with filgrastim is to mobilize stem cells more reliably than filgrastim can alone, with fewer days of apheresis sessions and fewer doses of filgrastim.
“We believe [motixafortide] will play a critical role in addressing unmet needs and introduce a new treatment paradigm for” patients with multiple myeloma, CEO Philip Serlin said in the release.
The drug approval was based on the GENESIS trial, which randomized 122 patients to either motixafortide plus filgrastim or placebo plus filgrastim.
BioLineRx said the trial included patients considered representative of the typical multiple myeloma population undergoing ASCT, with a median age of 63 years and with about 70% of patients in both arms of the trial receiving lenalidomide-containing induction therapy.
Motixafortide plus filgrastim enabled 67.5% of patients to achieve the stem cell collection goal of 6 million or more CD34+ cells/kg within two apheresis sessions, versus 9.5% of patients receiving the placebo plus filgrastim regimen. Additionally, 92.5% of patients reached the stem cell collection goal in up to two apheresis sessions in the motixafortide arm and 21.4% in the placebo arm.
However, “the data are descriptive and were not statistically powered nor prespecified. The information should be cautiously interpreted,” the company said.
Serious adverse reactions occurred in 5.4% of patients in the motixafortide arm, including vomiting, injection-site reaction, hypersensitivity reaction, injection-site cellulitis, hypokalemia, and hypoxia. The most common adverse reactions, occurring in more than 20% of patients, were injection site reactions (pain, erythema, and pruritus), pruritus, flushing, and back pain.
Labeling for the subcutaneous injection is available online.

RSV season has started, and this year could be different
The Centers for Disease Control and Prevention issued a national alert to health officials Sept. 5, urging them to offer new medicines that can prevent severe cases of the respiratory virus in very young children and in older people. Those two groups are at the highest risk of potentially deadly complications from RSV.
Typically, the CDC considers the start of RSV season to occur when the rate of positive tests for the virus goes above 3% for 2 consecutive weeks. In Florida, the rate has been around 5% in recent weeks, and in Georgia, there has been an increase in RSV-related hospitalizations. Most of the hospitalizations in Georgia have been among infants less than a year old.
“Historically, such regional increases have predicted the beginning of RSV season nationally, with increased RSV activity spreading north and west over the following 2-3 months,” the CDC said.
Most children have been infected with RSV by the time they are 2 years old. Historically, up to 80,000 children under 5 years old are hospitalized annually because of the virus, and between 100 and 300 die from complications each year.
Those figures could be drastically different this year because new preventive treatments are available.
The CDC recommends that all children under 8 months old receive the newly approved monoclonal antibody treatment nirsevimab (Beyfortus). Children up to 19 months old at high risk of severe complications from RSV are also eligible for the single-dose shot. In clinical trials, the treatment was 80% effective at preventing RSV infections from becoming so severe that children had to be hospitalized. The protection lasted about 5 months.
Older people are also at a heightened risk of severe illness from RSV, and two new vaccines are available this season. The vaccines are called Arexvy and Abrysvo, and the single-dose shots are approved for people ages 60 years and older. They are more than 80% effective at making severe lower respiratory complications less likely.
Last year’s RSV season started during the summer and peaked in October and November, which was earlier than usual. There’s no indication yet of when RSV season may peak this year. Last year and throughout the pandemic, RSV held its historical pattern of starting in Florida.
