MAIA Biotechnology, Inc. is expanding its ongoing Phase 2 clinical trial, THIO-101, to further assess the efficacy of its lead drug candidate, THIO, in combination with Regeneron's Libtayo® (cemiplimab) for treating third-line non-small cell lung cancer (NSCLC) patients. This decision follows promising interim results from the trial, which targets patients resistant to prior checkpoint inhibitor therapies and chemotherapy.
THIO-101 Trial Expansion and Interim Results
The amended clinical supply agreement with Regeneron, initially established in 2021, will provide additional Libtayo® for the expanded trial. MAIA Biotechnology sponsors the THIO-101 trial and holds an exclusive worldwide patent license to develop and commercialize THIO. The company is also contemplating an accelerated approval pathway in the United States based on the trial's outcomes.
The Phase 2 trial of THIO has demonstrated encouraging interim results. The trial evaluates THIO in combination with cemiplimab for patients who have not responded to two or more standard-of-care therapy regimens. The interim median survival follow-up for these third-line patients was reported at 10.6 months, which compares favorably to the standard-of-care overall survival of 5.8 months. Full efficacy results from the trial are anticipated within the current year. Sixteen patients surpassed a 12-month survival follow-up, nine of whom were third-line treatment patients.
