90.5% interim disease control rate (DCR) observed with combination therapy

Initial Part C efficacy observations align with previously reported THIO-101 clinical activity despite a more heavily pre-treated patient population

CHICAGO, July 08, 2026 (GLOBE NEWSWIRE) -- MAIA Biotechnology, Inc. (NYSE:MAIA) ("MAIA", the "Company"), a clinical-stage biopharmaceutical company focused on developing targeted immunotherapies for cancer, today announced positive initial efficacy data from its Phase 2 THIO-101 clinical trial expansion, Part C, evaluating its lead candidate, ateganosine, a dual mechanism of action drug incorporating telomere targeting and immunogenicity, as a third-line (3L) therapy for patients with advanced non-small cell lung cancer (NSCLC). 

Initial data from the THIO-101 Part C 3L studies1 show a disease control rate (DCR) of 90.5% (19 out of 21 patients) in the efficacy evaluable population who had at least one tumor scan after starting treatment. Patients are treated with ateganosine followed by cemiplimab (Libtayo®) in cycles of 21 days. Current chemotherapy treatments deliver an approximate 25-35% disease control rate.2
