• Inmagene exercised its option under the previously announced collaboration agreement to obtain an exclusive, royalty-bearing license for IMG-007, an anti-OX40 monoclonal antibody (mAb) and IMG-004, a Bruton Tyrosine Kinase (BTK) inhibitor
• Inmagene retains rights to develop and commercialize both assets worldwide

SAN DIEGO, Feb. 2, 2024 /PRNewswire/ -- Inmagene Biopharmaceuticals ("Inmagene" or the "Company"), a clinical stage biotechnology company developing innovative and differentiated therapies for immunological and inflammatory (I&I) diseases, today announced that it exercised the option to obtain an exclusive, worldwide and royalty-bearing license for IMG-007, a non-depleting humanized anti-OX40 mAb, and IMG-004, an oral non-covalent and reversible BTK inhibitor, with the right to sublicense through multiple tiers. 

The option was exercised pursuant to a collaboration between Inmagene and HUTCHMED (Nasdaq/AIM:HCM) announced in 2021 to develop and commercialize a portfolio of drug candidates for I&I diseases.

"Our strategic partnership with HUTCHMED has allowed us to take IMG-007 and IMG-004, two assets with best-in-class potential, from pre-clinical to clinical development," said Jonathan Wang, Ph.D., Chief Executive Officer of Inmagene. "Obtaining the worldwide exclusive rights is another step forward in our journey to become a global leader in novel drug development for I&I diseases."

IMG-007 is being evaluated in Phase 2a studies in two indications: moderate-to-severe atopic dermatitis and alopecia areata. IMG-004 is being evaluated in a Phase 1 multiple ascending dose (MAD) study.

About Inmagene

Inmagene is a global clinical-stage biotechnology company developing novel therapeutics for I&I diseases. The company's highly differentiated clinical-stage pipeline has multiple candidates with best-in-class potential. The lead asset IMG-007, a non-depleting anti-OX40 mAb, is in two global Phase 2a clinical trials in atopic dermatitis and alopecia areata. IMG-004, a non-covalent reversible BTK inhibitor is in a Phase 1 multiple ascending dose (MAD) study. IMG-008, an in-house developed long-acting anti-IL-36R mAb is entering global Phase 1 clinical development.

About IMG-007

IMG-007 is a humanized anti-OX40 IgG1 mAb, with an elongated half-life and silenced ADCC function. OX40-OX40L axis is important in T cell activation, expansion, and survival, thereby having an important role in the pathogenesis of a spectrum of I&I diseases. In nonclinical studies, IMG-007 demonstrated the ability to selectively and potently block the signaling between OX40 and OX40L. Phase 1 SAD data suggests a 31-day half-life at anticipated therapeutic dose levels, enabling the potential for once every 12 weeks (Q12W) dosing, and a favorable safety profile without any pyrexia and chills, differentiating from similar molecules in development. It is being evaluated for the treatment of moderate-to-severe atopic dermatitis and alopecia areata in two Phase 2a studies.

About IMG-004

Designed specifically for inflammatory and autoimmune diseases that usually require long-term treatment, IMG-004 is a reversible, non-covalent, potent, highly selective and brain permeable oral agent. Phase 1 SAD study results suggest a long half-life and durable pharmacodynamics (PD) effect, enabling the potential for once-daily (QD) dosing. Following the ongoing Phase 1 MAD study, IMG-004 will be evaluated in chronic spontaneous urticaria (CSU) and rheumatoid arthritis (RA).
