As big pharmas including Takeda and Novo Nordisk flee the cell therapy space and smaller biotechs shutter their operations, these players are sticking around to take the modality as far as it can go.
This year has seen the approval of several first-in-class therapies for HAE, but in a fragmented space, experts question whether they will be enough to net their developers a significant share of the entrenched market.
A coordinated national effort is emerging to bring alternatives to animal testing into routine preclinical use, backed by a fresh FDA roadmap and a global coalition of scientific and industry partners.
Novo Nordisk’s amycretin showed no weight-loss plateau over 36 weeks in patients with type 2 diabetes, suggesting its efficacy could become even stronger with longer follow-up, according to analysts at BMO Capital Markets.
Tecvayli plus Darzalex led to an 83% boost to progression-free survival versus the current standard therapy in relapsed or refractory multiple myeloma, results analysts at Guggenheim Securities called “remarkable.”
Johnson & Johnson will discontinue the Phase II Auτonomy study of posdinemab after a scheduled review found the anti-tau antibody failed to slow clinical decline in patients with early Alzheimer’s disease.
Analysts agree that the failure of Novo Nordisk’s semaglutide to reduce Alzheimer’s disease progression removes a “modest” or “perceived” overhang on Biogen and the anti-amyloid antibody class in general, clearing the way for increased uptake of Leqembi and Eli Lilly’s Kisunla.
“We felt we had a responsibility to explore semaglutide’s potential, despite a low likelihood of success,” Martin Holst Lange, Novo’s R&D chief, said on Monday.
NervGen will meet with the FDA early next year to align on a regulatory path forward for NVG-291 in chronic spinal cord injury.
Asundexian’s Phase III win could also bode well for Bristol Myers Squibb, which is also developing a Factor XIa inhibitor called milvexian for stroke prevention, analysts said.
