Item 8.01 | Other Events. |
On December 19, 2023, MAIA Biotechnology, Inc. (the “Company”) issued a press release announcing dose selection for THIO-101, a Phase 2 clinical trial evaluating the Company’s lead asset, THIO, in sequential combination with Regeneron’s anti-PD-1 cemiplimab (Libtayo®) in patients with advanced non-small cell lung cancer (“NSCLC”). During the dose-finding stage of THIO-101, patients were administered either 60mg, 180mg, or 360mg of THIO per cycle, followed by 350mg of cemiplimab (Libtayo®). The Company determined that the selected dose, 180mg/cycle, presented a better safety profile and outperformed the other doses in the key measures of efficacy for NSCLC trials. The Company plans to treat all future trial participants in THIO-101 with 180mg of THIO per cycle. Additionally, the Company plans to pursue accelerated approval for THIO in the United States for the treatment of patients with advanced NSCLC.
A copy of the press release is filed herewith as Exhibit 99.1 and is incorporated herein by reference.

MAIA Biotechnology Announces Dose Selection in THIO-101 Phase 2 Clinical Trial for Non-Small Cell Lung Cancer
| Selected dose shows unprecedented disease control and overall response rates in a NSCLC clinical trial |
CHICAGO, IL December 19, 2023 MAIA Biotechnology, Inc., (NYSE American: MAIA) (MAIA or the Company), a clinical-stage biopharmaceutical company developing telomere-targeting immunotherapies for cancer, today announced dose selection for THIO-101, a Phase 2 clinical trial evaluating its lead asset, THIO, in sequential combination with Regenerons anti-PD-1 cemiplimab (Libtayo®) in patients with advanced non-small cell lung cancer (NSCLC).
During the dose-finding stage of THIO-101, patients were administered either 60mg, 180mg, or 360mg of THIO per cycle, followed by 350mg of cemiplimab (Libtayo®). The selected dose, 180mg/cycle, presented better safety profile and outperformed the other doses in the key measures of efficacy for NSCLC trials. Subsequently, all future trial participants will be treated with THIO 180mg/cycle.
All THIO dose levels tested exceeded the disease control rate (DCR) thresholds in Stage 1 of the THIO-101 Phase 2 trial. We observed disease control in the first 8 to 9 patients with a post baseline scan in each arm, beating our goal of disease control in 8 out of 19 patients per arm. Among the three studied doses, the 180mg dose showed stronger DCR and preliminary response rates compared to other doses, said Vlad Vitoc, M.D., MAIAs Chairman and Chief Executive Officer.
These results are particularly impressive in this pool of patients who were heavily pre-treated and resistant to prior treatments with immune checkpoint inhibitors, a group that does not yet have standard of care treatment. We are highly encouraged by the unprecedented clinical data generated thus far in our Phase 2 trial, and as we move forward, we plan to pursue accelerated approval for THIO in the U.S. for the treatment of patients with advanced NSCLC. We believe THIOs DCRs and ORRs in second line treatment suggest the drugs potential to define the standard of care for this NSCLC patient population.
THIO is the only direct telomere targeting agent currently undergoing clinical development in the field of cancer drug discovery and treatment.
About THIO
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 (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 typespecific 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 Trial
THIO-101 is a multicenter, open-label, dose finding Phase 2 clinical trial. It is the first trial designed to evaluate THIOs 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 cemiplimab (Libtayo®) followed by THIO has been generally well-tolerated to date in a heavily pre-treated population. For more information on this Phase II trial, please visit ClinicalTrials.gov using the identifier NCT05208944.
