Jan 2025Series ANew Enterprise Associates (lead); Norwest (lead); TPG (lead); GSK; Boyu Capital; Monograph Capital; UPMC Enterprises; LongRiver Investments$120MOuro Medicines is a San Francisco-based biotechnology company developing immune reset therapeutics using T cell engagers to deplete B cells and treat chronic immune-mediated diseases such as systemic lupus erythematosus, scleroderma, rheumatoid arthritis, Sjögren’s syndrome, and myositis, aiming for durable remissions without ongoing immunosuppression. The company launched in January 2025 with a $120 million Series A funding round co-led by TPG Life Sciences Innovations, New Enterprise Associates (NEA), and Norwest Venture Partners, with participation from founders Monograph Capital and GSK, plus UPMC Enterprises, Boyu/Zoo Capital, LongRiver Investments, and others. Ouro was founded by Monograph Capital in partnership with GSK and acquired ex-China rights to its lead clinical-stage asset OM336, a BCMA-directed bispecific T cell engager, from Keymed Biosciences for an upfront $16 million plus up to $610 million in milestones; OM336 had prior data from 70 multiple myeloma patients and Ouro plans a Phase 1 trial in B cell-mediated diseases in 2025. The funding will advance the OM336 program into clinical development and build discovery efforts targeting unique B cell subsets and next-generation T cell engagers. Leadership includes CEO Jaideep Dudani, a Monograph portfolio principal and veteran of Human Immunology Biosciences (acquired by Biogen) and Hi-Bio (acquired by Biogen), chief medical officer Neely Mozaffarian (ex-GentiBio, J&J, Gilead), chief development officer Kevin Baker (ex-Pionyr), and chief administrative officer Christina Carlson (ex-Hi-Bio). Board additions include representatives from TPG, NEA, Norwest, Monograph, and Keymed. Ouro enters a competitive field of T cell engagers shifting from oncology to autoimmune applications, amid robust biopharma investment; GSK's involvement builds on its TCE partnerships like a $300 million deal with Chimagen Biosciences.
