Optimism for the GoCAR-T program had perked somewhat after a mid-February update, but hopes were definitively dashed as Bellicum Pharmaceuticals Inc. made known March 15 its decision to quit the phase I/II study testing two prospects in heavily pretreated cancer. The Houston-based firm’s stock (NASDAQ:BLCM) closed at 43 cents, down 50%, as Wall Street reacted to news regarding the study, designed to test GoCAR-T cell prospects BPX-601 and BPX-603 when combined with the activating agent rimiducid, a lipid-permeable tacrolimus analogue.
Les Laboratoires Servier SAS is touting its phase III win with vorasidenib as the first major advance in decades for low-grade glioma, with the trial called Indigo scoring statistical significance on two measures against residual or recurrent isocitrate dehydrogenase-mutant disease. The Suresnes, France-based firm said Indigo met the primary endpoint of progression-free survival (PFS) and the key secondary endpoint of time to next intervention (TTNI). The results of the prespecified interim analysis proved not only statistically significant but also clinically meaningful in PFS and TTNI.
Shares of Provention Bio Inc. (NASDAQ:PRVB) closed March 13 at $24.10, up $17.40, or 259%, after Wall Street learned that collaborator Sanofi SA intends to acquire the firm for $25 per share in cash, which works out to an equity value of about $2.9 billion. The transaction brings Paris-based Sanofi the type 1 diabetes (T1D) therapy Tzield (teplizumab-mzwv), approved by the U.S. FDA in 2022 as the first and only therapy to delay the onset of stage 3 disease in adults and in pediatric patients ages 8 and older with T1D that has reached stage 2.

Bionomics Ltd. is gearing up for an end-of-phase-II meeting with the U.S. FDA later this year to discuss the full results from the phase II study called Prevail in social anxiety disorder (SAD) with BNC-210, which missed its primary endpoint but yielded encouraging signs. Top-line data were disclosed last December. An oral alpha-7 nicotinic acetylcholine receptor negative allosteric modulator, BNC-210 fell short in change from baseline to the average of the Subjective Unites of Distress Scale (SUDS) during a five-minute public speaking challenge.
Another step forward in the quest for an Epstein-Barr virus (EBV) vaccine took the form of Merck & Co. Inc.’s deal with Modex Therapeutics Inc., owned by Opko Health Inc., to advance MDX-2201 worldwide, an arrangement that brings $50 million up front for Opko plus as much as $872.5 million in milestone payments along with royalties.
Findings published in Nature showing that dual blockage of PD-L1 and CD47 can boost the therapeutic effects of oxaliplatin chemotherapy as well as the FOLFOX regimen – in a CT-26 mice tumor model, anyway – served to highlight CD47, a target that has spurred added efforts of late.
