MAIA Biotechnology announced that the U.S. Food and Drug Administration has cleared an amendment to update its investigational new drug application which enables MAIA to open U.S. enrollment for the expansion of the Phase 2 THIO-101 trial of its lead candidate, ateganosine, as a treatment for advanced non-small cell lung cancer. Ateganosine is a novel dual mechanism of action drug candidate incorporating telomere targeting and immunogenicity. Ateganosine sequenced with a monoclonal antibody checkpoint inhibitor is being evaluated as a therapy for patients in ongoing Phase 2 and Phase 3 clinical trials. MAIA obtained FDA clearance of its updated IND highlighting MAIA's improved efficiencies to its manufacturing capabilities, including new manufacturers, formulation and storage conditions for ateganosine, and MAIA is now cleared to enroll patients in the U.S. for the expansion of the Phase 2 THIO-101 study of patients receiving advanced third-line NSCLC treatment. In addition to the U.S., the THIO-101 study is ongoing at 44 clinical sites in six countries. MAIA recently activated its first U.S. clinical site at Summit Medical Group in New Jersey.

About MAIA
MAIA Biotechnology, Inc. is a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer. The Company's THIO (6-thio-dG, 6-thio-2'-deoxyguanosine), is a lead asset, is an investigational dual mechanism of action drug candidate incorporating telomere targeting and immunogenicity. The modified nucleotide 6-thio-2-deoxyguanosine (THIO) induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. THIO-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment with THIO followed by PD-(L)1 inhibitors resulted in tumor regression in advanced, in vivo cancer models by induction of cancer type-specific immune memory. THIO is being developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.

MAIA Biotechnology Activates Clinical Trial Site in Georgia
- Trial Expansion: MAIA Biotechnology has activated its THIO-101 expansion trial at the Winship Cancer Institute in Georgia, now enrolling patients to evaluate the efficacy of its lead immunotherapy agent, ateganosine, for non-small cell lung cancer, marking a significant advancement in its clinical stage.
- Addressing Treatment Gaps: Lung cancer is the leading cause of cancer-related deaths in Georgia, with over 7,300 new cases expected in 2025; if approved, MAIA's ateganosine could fill a critical void in treatment options for advanced non-small cell lung cancer patients lacking FDA-approved therapies, highlighting its clinical importance.
- Promising Early Efficacy: Initial results from the THIO-101 trial indicate that some patients have exceeded two years of survival, suggesting that the combination of ateganosine and PD-(L)1 inhibitors may lead to durable tumor regression in patients resistant to existing therapies, showcasing a strong clinical outlook.
- Strong Research Team: The Winship Cancer Institute boasts a premier thoracic oncology clinical research team, with principal investigator Dr. Ticiana Leal having extensive experience in lung cancer chemotherapy and immunotherapy, ensuring high quality and effectiveness of the trial.
