- Survival Milestone: In the THIO-101 trial, eight patients survived beyond two years after receiving Ateganosine followed by Cemiplimab, significantly exceeding standard survival expectations for late-stage non-small cell lung cancer patients, indicating the potential breakthrough nature of this therapy.
- Remarkable Efficacy: One third-line patient achieved 33 months of survival, far surpassing the expected 5.8 months, while four second-line patients lived beyond 30 months, well above the documented 10.5-month survival typically seen with chemotherapy or checkpoint inhibitors alone, highlighting the treatment's effectiveness.
- Trial Design Highlights: THIO-101 is a multicenter, open-label Phase 2 study primarily assessing safety and anti-tumor activity, currently expanding into Part C with plans to enroll 48 additional patients in Asia and Europe, demonstrating an acceptable safety profile in a heavily pre-treated population.
- Broad Market Potential: MAIA aims to develop Ateganosine as a second-line or later treatment for non-small cell lung cancer patients, with the global immunotherapy market projected to exceed $50 billion, positioning Ateganosine as a potential entrant with a novel mechanism and differentiated clinical profile.

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.
