MAIA Biotechnology Activates Second U.S. Clinical Site For International Phase 2 THIO-101 Expansion Trial MAIA Biotechnology, Inc. has activated the second U.S. clinical site in its Phase 2 THIO-101 expansion trial at Central Alabama Research in Homewood, Alabama. The expansion part of THIO-101 evaluates MAIA's lead investigational therapy, ateganosine, a dual-action molecule incorporating telomere targeting and immunogenicity, as a third-line (3L) treatment for non-small cell lung cancer (NSCLC) in patients who have previously failed treatment with checkpoint inhibitors (CPIs) and chemotherapy. Parts A and B of the Phase 2 THIO-101 Phase 2 trial provided key inputs for MAIA's market strategy by identifying optimal dosing for a well-defined patient population. The THIO-101 expansion trial is ongoing in Europe and Asia with 44 active sites in 6 countries along with 2 in the U.S. The additional data from the trial's expansion may further support an accelerated approval filing with the FDA. In parallel with the Phase 2 clinical trial, MAIA is actively screening and enrolling patients in a pivotal Phase 3 clinical trial designed to assess overall survival for ateganosine sequenced with a CPI compared to investigator's choice of chemotherapy in a 1:1 randomization of up to 300 patients. MAIA has received regulatory approval to screen patients in Taiwan, Turkey, select European Medicines Agency (EMA) countries, and Georgia. Ateganosine (THIO, 6-thio-dG or 6-thio-2'-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in non-small cell lung cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2'-deoxyguanosine induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. Ateganosine-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment of ateganosine followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. Ateganosine is presently 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. THIO-101 is a multicenter, open-label, dose finding Phase 2 clinical trial. It is the first trial designed to evaluate ateganosine's anti-tumor activity when followed by PD-(L)1 inhibition. The trial is testing the hypothesis that low doses of ateganosine administered prior to cemiplimab (Libtayo®) will enhance and prolong immune response in patients with advanced NSCLC who previously did not respond or developed resistance and progressed after first-line treatment regimen containing another checkpoint inhibitor. The trial design has two primary objectives: (1) to evaluate the safety and tolerability of ateganosine administered as an anticancer compound and a priming immune activator (2) to assess the clinical efficacy of ateganosine using Overall Response Rate (ORR) as the primary clinical endpoint. The expansion of the study will assess overall response rates (ORR) in advanced NSCLC patients receiving third line (3L) therapy who were resistant to previous checkpoint inhibitor treatments (CPI) and chemotherapy. Treatment with ateganosine followed by cemiplimab (Libtayo®) has shown an acceptable safety profile to date in a heavily pre-treated population.

MAIA Biotechnology, Inc. Reports Strong Enrollment and Dosing Momentum in Pivotal Phase 3 Non-Small Cell Lung Cancer Trial MAIA Biotechnology, Inc. provided a patient enrollment update for its ongoing pivotal Phase 3 trial, THIO-104, evaluating its novel telomere-targeting therapy as a third-line (3L) treatment for advanced non-small cell lung cancer (NSCLC). To date, 29 patients have been dosed among 34 activated trial sites in 6 foreign countries. Statistical assessments of MAIA’s lead therapeutic, ateganosine, suggest a high probability of technical success in the THIO-104 full approval trial if Phase 3 data is consistent with Phase 2 THIO-101 trial results. Median overall survival was 17.8 months in parts A and B of the Phase 2 trial. With chemotherapy, which is the standard utilized treatment for 3L NSCLC patients, expected survival in a heavily pre-treated population is 5.8 months. Ateganosine is a first-of-its-kind dual mechanism therapy designed to break down telomere structure and function in cancer cells while inducing immune activation. Ateganosine holds substantial commercial opportunity in a projected $70 billion global NSCLC treatment market by 2030. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ateganosine as a 3L NSCLC treatment.

The trial has two primary objectives: (1) to assess the clinical efficacy of ateganosine compared to investigator’s choice of chemotherapy, using median Overall Survival (OS) as the primary clinical endpoint (2) to evaluate the safety and tolerability of ateganosine in sequential combination with a checkpoint inhibitor.
