ImageneBio, Inc. files a prospectus supplement registering 2,508,337 shares of Common Stock for resale by identified selling stockholders. The supplement incorporates a Form 8-K disclosing a related private placement of pre-funded warrants to purchase up to 5,770,335 Warrant Shares at $5.199 per Warrant Share for gross proceeds of approximately $30 million, with the pre-funded warrants exercisable at $0.001 per share and subject to beneficial ownership limits (including 19.99%). The registration covers resale by selling holders; proceeds from those resales will go to the selling holders, not the company.
ImageneBio, Inc. entered into a private placement on April 12, 2026, agreeing to sell pre-funded warrants to institutional and accredited investors for approximately $30 million of gross proceeds. The warrants cover up to 5,770,335 shares of common stock at a purchase price of $5.199 per Warrant Share, with a nominal exercise price of $0.001 per share and no expiration until fully exercised.
The warrants include a beneficial ownership cap that prevents any holder from exceeding 19.99% ownership through exercise. In a related Registration Rights Agreement, the company commits to file a resale registration statement for the warrant shares within three business days following August 1, 2026, with cash penalties if it fails to meet certain registration obligations. ImageneBio plans to use the net proceeds, together with existing cash, to support late-phase development readiness in atopic dermatitis and to expand development of its IMG-007 program into additional indications, including alopecia areata.
ImageneBio, Inc. reported that Chief Executive Officer Kristin Yarema received new equity awards as part of her compensation. She was granted an option to buy 128,100 shares of common stock at an exercise price of $6.20 per share, vesting over four years starting March 15, 2027. She also received 85,400 restricted stock units, each convertible into one share of common stock, with 25% vesting on March 15, 2027 and the rest in equal quarterly installments over the following three years, subject to continued service.
ImageneBio, Inc. announced that it has agreed to a mutual separation with Erin Butler, its Senior Vice President, Finance & Administration and Principal Accounting Officer, effective March 20, 2026. After that date, she will no longer serve as the company’s Principal Accounting Officer and is expected to receive severance benefits under her existing Severance Rights Agreement.
The board of directors has appointed Bob Lally, age 63, currently Senior Vice President, Finance & Operations, to serve as Principal Accounting Officer effective as of the same date. The filing describes Mr. Lally’s prior senior finance and operations roles at Ikena Oncology, Prevail Therapeutics and Arsanis, and notes he did not enter into any new material agreement, has no family relationships with directors or officers, and is not involved in related-party transactions requiring disclosure.
ImageneBio, Inc., formerly Ikena Oncology, completed its merger with Legacy Inmagene and now operates as a clinical-stage biopharmaceutical company focused on immune and inflammatory diseases. The business centers on IMG-007, a non-depleting anti-OX40 antibody initially developed for moderate-to-severe atopic dermatitis.
Early Phase 1b/2a data in atopic dermatitis showed meaningful and durable responses, including EASI‑75 rates of 54% and EASI‑90 rates of 31% at Week 16 after a four-week IV dosing period, with sustained biomarker improvements across Th1, Th2 and Th17 pathways. A multi-country Phase 2b subcutaneous dose-finding trial in atopic dermatitis is under way, with topline data expected in 2027.
The company sees IMG-007 as a potential “pipeline within a product,” with exploratory work in alopecia areata and possible future indications such as asthma, rheumatoid arthritis and hidradenitis suppurativa. However, the business remains entirely dependent on IMG-007’s success, expects significant ongoing losses, requires substantial additional funding, faces intense competition from established biologics and JAK inhibitors, and has disclosed a material weakness in internal controls over financial reporting.
ImageneBio, Inc. reported fourth quarter and full-year 2025 results and highlighted progress on its lead antibody IMG-007, now in the Phase 2b ADAPTIVE trial for moderate-to-severe atopic dermatitis.
For 2025, license revenue was $800 thousand compared with $3.5 million in 2024, reflecting lower collaboration income. Research and development expenses were $28.5 million and general and administrative expenses were $20.7 million, bringing total operating expenses to $49.3 million.
Net loss for 2025 was $45.3 million versus $36.6 million in 2024, as the company invested in building out operations after a reverse merger with Ikena Oncology and incurred transaction-related costs. Imagene ended 2025 with $135.3 million in cash, cash equivalents, and marketable securities, up from $12.1 million a year earlier, supported by the merger and a concurrent $75.0 million private placement.
