A vaccine for dengue fever, an advanced therapy for a complication after transplants, and a potential first-in-class drug for a form of psoriasis were among medicines recommended for approval by European regulators on Oct. 14.
Atara Biotherapeutics Inc.’s eagerly awaited update on the phase II Embold study testing ATA-188 in progressive multiple sclerosis (MS) left investors scratching their heads, and shares (NASDAQ:ATRA) closed at $3.89, down $4.77, or 55%.
Atara Biotherapeutics Inc. is keeping the faith and figuring out next steps with its next-generation, mesothelin-directed CAR T-cell therapies after Bayer AG ended their exclusive worldwide licensing agreement, signed in late 2020. The setup included funding and development of ATA-3271, an armored allogeneic T-cell immunotherapy, and an autologous version, ATA-2271, for high mesothelin-expressing tumors such as malignant pleural mesothelioma and non-small-cell lung cancer.
As the six-month interim analysis of phase II data for ATA-199 in progressive forms of multiple sclerosis (MS) nears, investors in Atara Biotherapeutics Inc. – not to mention patients – are growing more intrigued by the prospect, an off-the-shelf T-cell candidate that targets Epstein Barr virus-infected B cells and plasma cells in the central nervous system.
Atara Biotherapeutics Inc. licensed a pair of mesothelin-directed CAR T treatments, ATA-2271 and ATA-3271, to Bayer AG for $60 million up front with the potential for $610 million in development, regulatory and commercialization milestone payments. Atara is also eligible for tiered royalties that peak in the low double-digit percentage of net sales of the two drugs. South San Francisco-based Atara will provide translational and clinical manufacturing services for the two drugs that will be reimbursed by Bayer.
