By Tyler Patchen Samsung Bioepis has inked a settlement and license agreement with Johnson & Johnson, which will settle all U.S. patent litigation and allow for the commercialization of a biosimilar for the arthritis drug Stelara, known as SB17. According to Thursday’s announcement, Samsung Bioepis’ license period for its Stelara biosimilar will kick in on February 22, 2025. However, all the other terms of the deal were labeled as confidential and no further details were revealed. The BLA for the SB17 drug is under review by the FDA. If the drug is approved, it will be commercialized by Sandoz. The issues between J&J and Samsung Bioepis come from the South Korean biotech filing a petition for an Inter Partes Review of J&J’s Stelara, or ustekinumab patent. According to a legal intelligence website lexology, Samsung Bioepis stated that the claims of J&J’s patent were invalid. Patent protections over the use of ...
The US Food and Drug Administration (FDA) has announced its intention to investigate the safety of CAR-T therapies following reports that they could be linked to the development of T-cell cancers. Following reports from clinical trials and post-marketing adverse event data sources, the wide probe is directed at patients who received treatment with all currently approved BCMA- or CD19-directed autologous CAR-T cell immunotherapies. CAR-T-cell therapy is a type of immunotherapy that involves collecting and using patients’ own immune cells to treat conditions including lymphoma, leukaemia and multiple myeloma. T-cell malignancies have been seen in patients treated with several approved products in the class, including Bristol Myers Squibb’s (BMS) Abecma (idecabtagene vicleucel) and Breyanzi (lisocabtagene maraleucel), Johnson & Johnson and Legend Biotech’s Carvykti (ciltacabtagene autoleucel), Novartis’s Kymriah (tisagenlecleucel), and Gilead and Kite’s Yescarta’s Tecartus (brexucabtagene autoleucel) and Yescarta (axicabtagene ciloleucel). Currently, the potential risk of developing secondary malignancies is labelled as ...
The US Food and Drug Administration (FDA) has started an investigation to review the safety of chimeric antigen receptor (CAR)-T cell immunotherapies following reports of T cell malignancies in patients who received these immunotherapies. The therapies under investigation include six approved B cell maturation antigen (BCMA)- or CD19-directed CAR-T cell therapies. The investigation follows reports collected from clinical trials and post-marketing adverse event surveillance. The FDA had required companies to conduct 15-year long term follow-up observational safety studies to assess the long-term safety and the risk of secondary malignancies as part of the respective therapy’s approval. The risk of post-therapy malignancies applies to all FDA-approved BCMA- or CD19-directed CAR-T cell therapies, as per a 28 November press release. The agency added that although the therapy benefits “continue to outweigh their potential risks for their approved uses”, the FDA is evaluating the need for regulatory action regarding the risk of T-cell ...
By Tyler Patchen Pictured: Exterior of an FDA building/iStock, Grandbrothers The FDA announced Tuesday that it is investigating the “serious risk” of malignancies in patients who received treatment with BCMA- or CD19-directed autologous CAR-T cell immunotherapies. The regulator said it has determined that the risk of T-cell malignancies “is applicable to all currently approved BCMA-directed and CD19-directed genetically modified autologous CAR T cell immunotherapies” including Bristol Myers Squibb’s Abcema and Breyanzi, Johnson & Johnson’s Carvykti, Novartis’ Kymriah and Gilead’s Tecartus and Yescarta. “T-cell malignancies have occurred in patients treated with several products in the class,” according to the FDA, which said it received reports from clinical trials and postmarketing adverse event data. While the agency said that the overall benefits of these products continue to outweigh their potential risks, it “is investigating the identified risk of T cell malignancy with serious outcomes, including hospitalization and death, and is evaluating the ...
In a blow to CAR-T therapies, the FDA is investigating a “serious risk” of patients developing new cancers after treatment with these highly efficacious oncology drugs. The FDA unveiled the probe Tuesday. The agency said it has received reports of T-cell malignancies, including CAR-positive lymphoma, among patients who received BCMA- or CD19-directed CAR-T cell immunotherapies. Some patients involved have had to be hospitalized or died, according to the agency. The cases stem from clinical trials and postmarketing adverse event surveillance, the FDA said. The FDA has determined that the potential risk is applicable to all currently approved CAR-T therapies, as T-cell malignancies have occurred after patients received several different products. The FDA is now weighing potential regulatory action—even as the potential risk of developing secondary cancer is already included as a class warning on the labels of the CAR-T therapies. Currently marketed CD19 CAR-Ts include Yescarta and Tecartus from Gilead ...
Pictured: Cancer cell surrounded by cytokines/iStock, Marcin Klapczynski Alkermes on Wednesday announced that it has completed the spinoff of its oncology business to become a pure-play neuroscience company. Mural Oncology will begin trading on the Nasdaq starting Thursday, with Alkermes shareholders receiving a share of Mural for every 10 shares of Alkermes. Mural is launching with $275 million, which is expected to fund it through the fourth quarter of 2025, and an interleukin-2 cytokine as its most advanced asset. Nemvaleukin alfa is being studied as a monotherapy for advanced mucosal or cutaneous melanoma in Phase II and is in a Phase III study in combination with Keytruda for platinum-resistant epithelial ovarian cancer. The therapeutic is designed to avoid the hallmark toxicities of IL-2 immunotherapies. The studies are potentially registrational with readouts expected in early 2025. Additional assets include therapies targeting IL-18 and IL-12. Mural will nominate a development candidate for each program in ...
GSK’s momelotinib has been recommended for approval by the European Medicines Agency’s human medicines committee as the first treatment option specifically indicated for myelofibrosis patients with moderate-to-severe anaemia. The Committee for Medicinal Products for Human Use (CHMP) has recommended that the drug be used to treat disease-related splenomegaly or symptoms in adult patients with moderate-to-severe anaemia who have primary myelofibrosis, post polycythaemia vera myelofibrosis or post essential thrombocythaemia myelofibrosis. Eligible patients will also have either not been treated with JAK inhibitors before or have been treated with Novartis’ Jakavi (ruxolitinib), GSK said. Myelofibrosis is a rare blood cancer that can lead to severely low blood counts, with about 40% of patients having moderate-to-severe anaemia at the time of diagnosis and nearly all patients developing anaemia at some point in the course of their disease. Transfusions are often required by myelofibrosis patients with anaemia and more than 30% will discontinue treatment ...
By Tristan Manalac Pictured: Entrance to the Department of Health and Human Services in Washington, DC/iStock The Department of Health and Human Services in a supplemental court filing posted late last week has suggested that Johnson & Johnson’s blockbuster psoriasis therapy Stelara (ustekinumab) might soon be “deselected” from the Inflation Reduction Act’s Drug Price Negotiation Program. The development comes after the FDA last week approved Amgen’s Wezlana (ustekinumab-auub), an interchangeable biosimilar to Stelara. In May 2023, Amgen and J&J settled their patent dispute over the biosimilar challenge to Stelara, allowing the entry of Wezlana “no later than January 1, 2025.” Under the current negotiation guidelines, the Centers for Medicare and Medicaid Services can reconsider a drug product for price negotiations when it is “subject to meaningful competition.” HHS referred to this provision in a separate October 2023 court filing, supporting its prior motion to dismiss a lawsuit filed by various ...
In a bid to further restructure operations, Sangamo plans to close its facility in Brisbane, California early in 2024, which will see 162 employees facing another round of layoffs. During the transition, the company will move its headquarters to its facility in Richmond, California, effective January 1, 2024. Sangamo will direct any freed resources towards advancing adeno-associated virus (AAV) capsid delivery technologies and its neurology epigenetic regulation portfolio via its investigational Nav1.7 and Prion disease therapies, said Sangamo CEO Sandy Macrae. Additionally, the company has decided to defer new investments for its Phase III Fabry and CAR-Treg studies and is instead actively seeking collaboration and investment partners for both programs. Sangamo is the latest to be swept in the wave of layoffs, following companies like NexImmune and Kinnate Biopharma, which sacked 53% and 70% of their respective workforces in September to redirect cash towards priority projects. In a conference call ...
Pictured: Handshake over a deal/iStock, PeopleImages Biopharma’s biggest royalties buyer is upping its stake in a popular spinal muscular atrophy drug. Royalty Pharma announced Thursday a $1 billion upfront payment to beleaguered PTC Therapeutics for additional royalties in Evrysdi, licensed and marketed by Roche. Royalty initially bought into Evrysdi in July 2020, just before its approval by the FDA. The drug has already been used to treat over 11,000 patients worldwide. Spinal muscular atrophy (SMA) is a rare and often fatal genetic disease that typically presents in infants and young children. The deal increases Royalty’s ownership of the Evrysdi royalty from 43% to 81%, equating to 13% of the royalties Roche pays on worldwide net product sales. Roche reported $801.4 million in sales for the first half of 2023. GlobalData predicts sales to rise to just under $3 billion in 2029. In Thursday’s announced deal, PTC has the option to sell the remainder of the Evrysdi royalty to Royalty for up ...
