Two phase III studies of setrusumab, Orbit and Cosmic, for treating brittle bones have failed and left the developers floundering on Wall Street. Neither of Ultragenyx Pharmaceutical Inc. and Mereo Biopharma Group plc’s studies of the monoclonal antibody in treating osteogenesis imperfecta hit statistical significance in their primary endpoints, though they did achieve their secondary endpoints. The companies are still looking at the numbers to determine their next steps.
Gene therapy has had its commercial struggles in the past year. The cost to patients is in the millions and fewer are stepping forward for treatment than companies would like. While development continues in this game-changing field, some have struggled with regulatory authorities during development while others have just stepped away altogether.
The U.S. FDA’s green lighting of Omeros Corp.’s Yartemlea (narsoplimab) makes it the first approved treatment for hematopoietic stem cell transplant-associated thrombotic microangiopathy (TA-TMA), a life-threatening complication of hematopoietic stem cell (HSC) transplantation. The BLA for narsoplimab, a fully human monoclonal antibody that inhibits the enzyme mannan-binding lectin-associated serine protease-2, had a Dec. 26 PDUFA date.
Reviva Pharmaceuticals Holdings Inc. may be headed back to the clinic for another phase III study of brilaroxazine in treating schizophrenia. With a successful series of early and mid-stage studies behind the treatment, the U.S. FDA recommended a second study for the serotonin-dopamine and neuroinflammatory signaling modulator after a pre-NDA meeting in order to net more efficacy results and expand the safety dataset.
Daiichi Sankyo Inc. told BioWorld it voluntarily placed a partial hold in recruitment and enrollment in the phase III IDeate-Lung02 study of antibody-drug conjugate ifinatamab deruxtecan because of a higher than anticipated incidence of grade 5 interstitial lung disease events. The company did not say how many deaths there had been.
Harbour Biomed has added another collaboration to its end-of-year dealmaking, this time with Bristol Myers Squibb Co. (BMS) to develop multispecific antibodies. Harbour is getting about $90 million up front, but milestones could eventually top $1 billion.

Two large deals and an acquisition, totaling about $4.64 billion in all, are helping wrap up what’s turning out to be a strong year. Through the first 11 months of 2025, biopharma dealmaking was robust with a collective value of $261.14 billion, the highest January through November total of the past seven years and well above 2024’s $201.35 billion. These three December deals helped revive the surge in dealmaking that had cooled in November.
Positive top-line phase III data for Immunome Inc.’s oral, once daily treatment for progressing desmoid tumors have prompted the company to say it plans to submit an NDA to the U.S. FDA in the second quarter of next year. Varegacestat, an oral gamma secretase inhibitor, hit its primary endpoint by significantly improving progression-free survival compared to placebo. The small molecule produced a statistically significant and clinically meaningful improvement vs. placebo with its 84% reduction in the risk of disease progression or death.
