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 Reports Positive Initial Efficacy Data from THIO-101 Clinical Trial
- Significant Disease Control Rate: The THIO-101 Part C clinical trial shows a 90.5% disease control rate (19 out of 21 patients), significantly exceeding the 25-35% control rate of current chemotherapy, indicating the drug's potential in heavily pre-treated patients.
- Efficacy Consistency: Initial data aligns with previous results from Parts A and B, achieving an 88% disease control rate in third-line NSCLC patients, suggesting stable efficacy across different patient populations and potential new treatment options.
- Acceptable Safety Profile: The combination of ateganosine and cemiplimab has demonstrated an acceptable safety profile in heavily pre-treated patients, enhancing the company's confidence in cancer immunotherapy and potentially driving further clinical development.
- Completion of International Enrollment: MAIA has completed international enrollment for Part C of THIO-101, marking an expansion of the company's clinical trial capabilities globally, which is expected to accelerate the drug's market entry and enhance competitive positioning.
