A new version of a drug candidate that failed in a phase II for neuropathic pain 15 years ago has attracted $140 million in series D funds, plus an ex-North American deal worth up to $570 million, for Grin Therapeutics Inc.
History has repeated itself for Prothena Corp. plc, which has reported a second phase III miss for birtamimab in the treatment of light chain amyloidosis. Announcing the trial failure, the Dublin-based company said it is planning “a substantial reduction” of its organization.
A development deal with Biogen Inc. could eventually bring City Therapeutics Inc. about $1 billion in milestone payments. It’s a step in the direction the company had been going: looking for the right partners, including those from big pharma. Privately held City Therapeutics is getting $46 million in the deal. That includes $16 million as an up-front payment and an investment of $30 million in exchange for a City Therapeutics convertible note.
Annji Pharmaceutical Co. Ltd.’s rosolutamide (AJ-201, JM-17) achieved positive results in a phase I/II trial in adults with spinal and bulbar muscular atrophy, also known as Kennedy’s disease.
Sanofi SA made good on its plan to bear down on M&A by agreeing to buy Vigil Neuroscience Inc. for $8 per share (NASDAQ:VIGL). Included in the transaction is a non-tradeable contingent value right entitling the holder to potentially collect $2 per share more in cash, payable following the first commercial sale of the phase II-ready VG-3927, a small-molecule triggering receptor expressed on myeloid cells 2 (TREM2) antagonist for Alzheimer’s disease, if achieved within a specific period. Watertown, Mass.-based Vigil’s stock closed May 22 at $7.88, up $5.57, or 241%.
Orionis Biosciences Inc. is sticking with Genentech Inc. in a second deal to discover small-molecule monovalent glue therapies for treating cancer. Privately held Orionis is getting $105 million up front and could earn more than $2 billion in R&D, development, commercial and net sales milestones, plus royalties. The multiyear collaboration calls for Orionis to handle discovery and optimization of molecular glues, with Genentech in charge of later-stage preclinical and clinical development, regulatory filing and commercialization of any small molecules the partnership produces.
The credibility gap in psychedelic drug development continues to narrow with positive top-line data from a Beckley Psytech Ltd. phase IIa study in depression. The results keep the treatment into a tight race with GH Research plc, which also has an inhalable drug in development.
The merger of Protagenic Therapeutics Inc. and Phytanix Bio Inc. combines two different approaches to treating obesity and metabolic issues.

Mirroring results reported in a phase IIb study, Apnimed Inc.’s first of two pivotal trials testing AD-109 as an oral therapy in obstructive sleep apnea hit primary and secondary endpoints. Should similar findings emerge from a second phase III trial, expected to read out in a couple of months, the privately held firm anticipates a U.S. NDA filing in early 2026.
Therini Bio raised an additional $39 million in its series A financing round, bringing the total for the round to $75 million. The capital will be used to advance its fibrin-targeting immunotherapies for neurodegenerative diseases.
