Rhea-AI Summary
MAIA Biotechnology reported a new partial response in its Phase 2 THIO-101 trial evaluating ateganosine with cemiplimab in advanced non-small cell lung cancer patients. The responding patient showed stable disease for over 20 months before achieving a partial response, defined as a 30% tumor size reduction. The trial's data cutoff from May 15, 2025, demonstrated a median overall survival of 17.8 months among 22 NSCLC patients, with the longest survival reaching 24.3 months after 32 treatment cycles. This significantly outperforms standard-of-care chemotherapy treatments, which typically show 5-6 months overall survival in similar settings. The company plans to expand its THIO-101 pivotal Phase 2 trial to further assess overall response rates in third-line NSCLC patients resistant to previous treatments.
