MAIA Biotechnology's Experimental Cancer Drug Shows Tripled Survival Vs. Standard Chemotherapy In Pretreated Lung Cancer Patients
MAIA Biotechnology, Inc. (NASDAQ:MAIA) on Thursday revealed updated data from its THIO-101 pivotal Phase 2 clinical trial. The trial is evaluating its lead clinical candidate, ateganosine (THIO), sequenced with Regeneron Pharmaceutical Inc's (NASDAQ:REGN) immune checkpoint inhibitor (CPI) cemiplimab (Libtayo) for advanced non-small cell lung cancer (NSCLC) who are resistant to immune therapy and chemotherapy. As of May 15, third line (3L) data showed median overall survival (OS) of 17.8 months for the 22 NSCLC patients who received at least one dose of ateganosine (the intent-to-treat population) in parts A and B of the trial. The updated analysis demonstrates a 95% confidence interval (CI) lower bound of 12.5 months and a 99% CI lower bound of 10.8 treatment has been generally well-tolerated to date in this heavily pretreated population. At the data cutoff, the patient with the longest survival in the trial had completed 32 cycles of therapy and had 24.3 months survival. Studies of standard-of-care (SOC) chemotherapy treatments for NSCLC in a similar setting have shown OS of 5 to 6 months. 'This new benchmark of 17.8 months median OS is nearly triple the recognized SOC data for third-line NSCLC found in the medical literature. We believe this is a substantial indicator of the potential ateganosine has to shift the NSCLC treatment landscape,' said MAIA Chairman and CEO Vlad Vitoc. MAIA's multiple potential regulatory pathways for ateganosine could provide accelerated FDA approval and robust exclusivity in NSCLC, with a potential FDA decision as early as next year. The company announced a new partial response (PR) was identified in a patient after 20 months of treatment. A partial response is defined as a decrease in tumor size of at least 30%. 'The patient remained on treatment and we observed stable disease for more than twenty months before the partial response was identified, highlighting the efficacy, safety and low toxicity of the treatment,' Vitoc added. Price Action: MAIA stock is up 11.7% at $1.97 at the last check on Thursday. Read Next:Photo via Shutterstock UNLOCKED: 5 NEW TRADES EVERY WEEK.

MAIA Biotechnology Announces Design for Expansion of THIO-101 Phase 2 Trial in Advanced Non-Small Cell Lung Cancer
Expansion study to enroll patients in the U.S. and select countries in Europe and Asia Multiple milestones attainable for 2025 CHICAGO, February 26, 2025--(BUSINESS WIRE)--MAIA Biotechnology, Inc., (NYSE American: MAIA) ("MAIA," the "Company"), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced the trial design for the expansion of its THIO-101 pivotal Phase 2 trial in non-small cell lung cancer (NSCLC). Following successful outcomes to date in THIO-101, 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. The THIO-101 study in 3L will enroll up to 48 patients with two arms: Arm 1, continuing the evaluation of THIO sequenced with Libtayo® (cemiplimab); and Arm 2, evaluating THIO as a monotherapy, to further gain experience of THIO in the contribution of components. Treatment cycles for patients in both arms will administer THIO on 3 consecutive days, followed by immune activation on day 4. Arm 1 will administer Libtayo on day 5. The Company plans to enroll an additional 100 patients for the registration phase of the trial. MAIA expects to conduct the trials in the U.S. and select countries in Europe and Asia. MAIA recently announced an amended clinical supply agreement with Regeneron to include the expansion portion of THIO-101. Under terms of the amended agreement, MAIA continues to sponsor THIO-101 and Regeneron will provide Libtayo for the treatment of all patients including the additional patients in the expansion and potentially, the registration studies. "We are excited to start the expansion arm of our THIO-101 trial which is designed to determine overall response rates in third line NSCLC. We expect to have new patients enrolled in the coming weeks," said Vlad Vitoc, M.D., CEO of MAIA. "Through THIO-101 to date, THIO has delivered unprecedented disease control, response, and survival results. Continued efficacy and safety data generated by our study could support an FDA NDA submission directly, particularly as we plan to seek an accelerated approval of THIO in the U.S. "We have multiple milestones that we believe are attainable for 2025 and we look forward to keeping our shareholders and investors well informed of our progress on value creation," Dr. Vitoc added. As of January 15, 2025, data indicated that Median Overall Survival (OS) in third-line treatment was reached at 16.9 months, with a 95% confidence interval (CI) lower bound of 12.5 months and a 99% CI lower bound of 10.8 months). The treatment has been generally well-tolerated to date in this heavily pre-treated population1. ________________________________ 1 Details on safety can be found on the previously announced SITC 2024 presentation available on MAIA's website. About THIOTHIO (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 (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 profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. THIO 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. About THIO-101, a Phase 2 Clinical TrialTHIO-101 is a multicenter, open-label, dose finding Phase 2 clinical trial. It is the first trial designed to evaluate THIO's anti-tumor activity when followed by PD-(L)1 inhibition. The trial is testing the hypothesis that low doses of THIO 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 THIO administered as an anticancer compound and a priming immune activator (2) to assess the clinical efficacy of THIO using Overall Response Rate (ORR) as the primary clinical endpoint. Treatment with THIO followed by cemiplimab (Libtayo) has been generally well-tolerated to date in a heavily pre-treated population.
