ImageneBio, Inc. is a clinical-stage biopharmaceutical company focused on immunological and inflammatory diseases, led by its anti-OX40 antibody IMG-007 for atopic dermatitis and alopecia areata. For the three months ended March 31, 2026, it reported a net loss of $10.6 million, compared with $6.1 million a year earlier, as research and development expenses rose to $6.0 million and general and administrative expenses increased to $6.1 million.
Cash, cash equivalents and marketable securities totaled $117.2 million as of March 31, 2026. In April 2026, the company raised an additional $30.0 million through a private placement of pre-funded warrants to purchase up to 5,770,335 shares of common stock at a purchase price of $5.199 per warrant share and an exercise price of $0.001 per share. Management believes this funding, together with existing resources, can support operations for at least 12 months.
The company completed a reverse merger with Ikena Oncology and divested its non-OX40 assets in 2025, leaving IMG-007 as its sole clinical asset. A multi-country Phase 2b dose-finding study in atopic dermatitis is underway, with topline data expected in the fourth quarter of 2027, and a Phase 2 study in alopecia areata is planned to start by the end of 2026, with initial data anticipated in 2028.
