Ouro Medicines is a biotechnology company developing immune reset therapeutics using T cell engagers (TCEs) to treat chronic immune-mediated diseases like lupus, scleroderma, rheumatoid arthritis, Sjögren's disease, and idiopathic inflammatory myopathy (IIM).[1][2][3] Its lead product, OM336, a BCMA-targeting TCE licensed from Keymed Biosciences, depletes pathogenic B cells and plasma cells to achieve durable remissions without ongoing immunosuppression, initially tested in cancer but repurposed for autoimmune conditions.[2][3][4] The company serves patients with severe, refractory autoimmune diseases where current options are limited, solving the problem of chronic symptom management by enabling potential long-term cures through immune system "resets."[1][4][5] Launched in January 2025 with $120M in Series A funding co-led by TPG, NEA, and Norwest—plus backers like GSK and Monograph Capital—Ouro has shown rapid growth, expanding OM336 into Phase 1b trials by October 2025 and advancing internal discovery programs targeting unique B cell subsets.[1][3]
Ouro Medicines was founded in 2025 by Monograph Capital in partnership with GSK, emerging from stealth with $120M in funding to capitalize on emerging data from CAR-T therapies in autoimmune diseases.[1][5] Monograph, tracking immunology trends, collaborated with GSK—which has deep expertise in B-cell biology via drugs like Benlysta for lupus—to spin out this immune reset platform.[5] CEO Nisha Dudani, a portfolio principal at Monograph, leads the effort, with a leadership team experienced in relevant diseases and modalities; Chief Medical Officer Neely Mozaffarian, M.D., Ph.D., highlighted OM336's expansion into new indications.[1][3] Early traction came from licensing OM336 from China's Keymed Biosciences, where it reached Phase 2 in multiple myeloma; Ouro secured ex-China rights and dosed over 100 patients across oncology and autoimmune studies, earning FDA Orphan Drug Designation for autoimmune hemolytic anemia (AIHA).[2][3]
Ouro rides the TCE and cellular therapy wave in autoimmunity, inspired by German research showing remissions in lupus via B-cell depletion, sparking >12 clinical trials and investor interest from biotechs to Big Pharma.[2] Timing is ideal amid market forces like rising autoimmune prevalence, limitations of immunosuppressants, and TCE success in oncology (e.g., multiple myeloma approvals), enabling repurposing for high-need areas like scleroderma and IIM with few options.[2][3][4] Ouro influences the ecosystem by validating TCEs for "one-and-done" resets, potentially shifting standards from lifelong therapy to cures, while its GSK ties and $120M war chest accelerate validation amid competition from peers like Candid.[1][2][5]
Ouro's near-term focus is advancing OM336 through Phase 1b in Sjögren's/IIM and other B-cell diseases, while scaling discovery programs for broader immune resets.[3] Trends like expanding TCE/CAR-T data in autoimmunity and AI-driven protein engineering will propel its pipeline, with dosing insights resolving key questions on optimal regimens.[2] Its influence could grow by pioneering TCE cures, evolving from startup to category leader if remissions prove durable—echoing its ouroboros namesake of immune rebirth.[5]
Ouro Medicines has raised $120.0M across 1 funding round. Most recently, it raised $120.0M Series A in January 2025.
