Keros Therapeutics Inc. CEO Jasbir Seehra told BioWorld that he plans to use at his new company lessons learned as co-founder of Acceleron Pharma Inc., where work with receptors in the TGF-beta superfamily “taught me the potential of the biology and those molecules, but also the limitations” with regard to safety that need to be surmounted.

Aptevo Therapeutics Inc.’s chief scientific officer, Jane Gross, told BioWorld that the sale of the firm’s marketed recombinant hemophilia B therapeutic, Ixinity, to Medexus Pharmaceuticals Inc. allowed for a “cleaner message” to Wall Street. “It was a little difficult to explain having a commercial asset and an R&D pipeline,” she said.
