Inmagene Doses First Patient in Phase 2a Trial of IMG-007, an Anti-OX40 Monoclonal Antibody with an Extended Half-life, for the Treatment of Alopecia Areata

• IMG-007 is a novel anti-OX40 monoclonal antibody (mAb) engineered for potentially once every 12 weeks dosing and an improved safety profile
• IMG-007 is being evaluated for the treatment of alopecia areata (AA) and atopic dermatitis (AD)
• An interim data readout in AA is expected in Q3 2024

Excerpt from the Press Release:

SAN DIEGO, Oct. 13, 2023 /PRNewswire/ — Inmagene Biopharmaceuticals (“Inmagene”), a clinical stage biotechnology company developing innovative and differentiated therapies for immunological and inflammatory diseases, announced that the first patient has been dosed in a global multicenter Phase 2a study of IMG-007 in adult patients with AA. The study will evaluate the safety, efficacy, pharmacokinetics, and biomarkers of IMG-007 in AA patients with 50% or greater scalp hair loss. More information about the study can be found here NCT06060977.

“Alopecia areata is a devastating disease which affects approximately 147 million people globally. Currently, there are limited treatment options and no approved biologics for AA. Better treatment options are needed,” said Jonathan Wang, Ph.D., Chief Executive Officer of Inmagene. “IMG-007 could potentially provide a safe and effective biologic therapy with once every 12 weeks dosing regimen for AA patients.”

IMG-007 is a humanized IgG1 mAb that specifically binds to the OX40 receptor and potently blocks the signaling between OX40 and its ligand. IMG-007 has been engineered to have an extended half-life to allow less frequent dosing and a silenced antibody-dependent cell-mediated cytotoxicity (ADCC) function to reduce safety risks. In a Phase 1 study in healthy adult participants, IMG-007 has demonstrated a favorable safety profile, without any reports of pyrexia or chills. A single treatment of IMG-007 at projected therapeutic dose levels maintained the target exposure for 12 to 18 weeks, which may allow IMG-007 for every 12 weeks administration.
