• Combination THIO 180mg + cemiplimab achieved 38% overall response rate (ORR) in difficult-to-treat, third-line non-small cell lung cancer (NSCLC)
• ORR of 38% significantly exceeds standard of care ORR in NSCLC third-line in patients without a targetable mutation who progressed on checkpoint inhibitors and chemotherapy

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced positive efficacy data for third-line treatment in its Phase 2 THIO-101 clinical trial evaluating THIO sequenced with the immune checkpoint inhibitor (CPI) cemiplimab (Libtayo®) in advanced non-small cell lung cancer (NSCLC).

As of January 8, 2024, overall response rate (ORR), characterized as partial or complete response to therapy, was 38% (3 out of 8 patients) in the efficacy evaluable population for combination THIO 180mg + cemiplimab in third-line treatment for NSCLC patients who failed treatment with immune checkpoint inhibitors in prior lines of therapy, with or without chemotherapy.

“As an impressive measure of efficacy, the strong response rate of 38% in third-line treatment supports our premise that THIO administration prior to cemiplimab can improve tumor responses to immunotherapy in advanced NSCLC patients resistant to CPIs and other standard treatments,” said Vlad Vitoc, M.D., MAIA’s Chairman and Chief Executive Officer. “Around 60-70% of NSCLC patients do not have a targetable mutation and cannot benefit from a biomarker-targeted therapy, making it the greatest unmet medical need population in lung cancer. In currently available treatments for these patients in third-line, response rates range around 6%.¹ We are encouraged by the excellent efficacy findings in THIO-101 to date, adding impressive ORR to unprecented disease control rates (DCR), and further demonstrating the potential of our first-in-class treatment to redefine the standard of care for NSCLC patients.”

The efficacy evaluable population defined in the THIO-101 protocol considers all subjects who received at least one dose of THIO treatment and have at least one postbaseline tumor assessment (scans). Two third-line patients in the 180mg dose cohort did not have recorded scans at the data cutoff. Safety remained consistent with previous reports.

The Company recently announced early completion of enrollment in the THIO-101 trial. THIO-101 is expected to be the first completed clinical study of a telomere-targeting agent 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 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 Trial

THIO-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 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.

• Topline data expected in second half of 2024
• THIO-101 will be the first completed clinical study of a telomere targeting agent in the field of cancer drug discovery and treatment

CHICAGO, IL, Feb. 22, 2024 (GLOBE NEWSWIRE) — MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced that enrollment is now complete in its Phase 2 THIO-101 go-to-market clinical trial evaluating THIO sequenced with the immune checkpoint inhibitor (CPI) cemiplimab (Libtayo^®) in advanced non-small cell lung cancer (NSCLC).

The trial reached the enrollment target of 41 patients for the 180mg/dose on February 19, 2024. As of the latest data available for the trial, 79 patients had received either 60mg (24 patients), 180mg (41 patients) or 360mg (14 patients). The original trial design targeted up to 182 patients, including all patients in the safety lead-in and 41 patients in each of the 3 tested doses (60mg, 180mg, and 360mg). Following the selection of 180 mg/cycle as the optimal dose in December 2023, all patients were subsequently enrolled at the 180mg/cycle dose and trial enrollment was completed ahead of schedule.

“Enrollment in our Phase 2 THIO-101 trial has been strong from the start. With excellent results across all doses and our selection of the optimal dose in December 2023, we enrolled the necessary number of patients in the Simon 2-stage design to achieve our trial endpoints earlier than expected,” said Vlad Vitoc, M.D., MAIA’s Chairman and Chief Executive Officer. “THIO-101 preliminary data has demonstrated unprecedented rates of disease control and response to date, and we look forward to the long-term efficacy results as we continue to monitor the enrolled patients in the upcoming months. As the only direct telomere targeting agent currently undergoing clinical development in the field of cancer, we believe THIO holds a time-to-market advantage and strong potential to become a new standard of care for NSCLC.”

The main objectives of the THIO-101 trial are to evaluate the safety, tolerability, and preliminary clinical efficacy of THIO in patients with advanced NSCLC who have experienced disease progression or relapse after initial treatments with an immune CPI alone or in combination with chemotherapy.

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 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 Trial

THIO-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 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.

• THIO treatment leads to profound activation of innate and adaptive anti-tumor responses
• THIO depletes cancer initiating cells (CICs) and thus diminishes tumor initiation and metastasis-forming potential in various in vivo models
• THIO previously awarded orphan drug designation (ODD) by FDA for small cell lung cancer (SCLC) treatment

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced the publication of extensive work describing preclinical studies for lead candidate THIO in small cell lung cancer (SCLC) in the peer-reviewed scientific journal Nature Communications. The reported findings from the research, conducted in collaboration with the University of Texas Southwestern (UTSW) scientists, led by corresponding author Dr. Esra Akbay, demonstrate the immune-enhancing, metastasis-reducing effects of MAIA’s telomere-targeting agent THIO (6TdG) in several well-characterized in vitro and in vivo models of SCLC.

“This publication highlights a rather unique dual mechanism of action for THIO as a first-in-clinic telomere-targeted anticancer agent for potential treatment of SCLC,” said Sergei M. Gryaznov, PhD., MAIA’s Chief Scientific Officer. “In addition to the direct and potent cancer cell depletion activity, the observed specific interferons stimulation, immune responses-enhancement, and metastasis-reducing effects of THIO provide solid scientific foundation for further advancement of this compound in clinical development.”

A prominent characteristic of lung cancer small cells is their reliance on telomerase activity, a key enzyme essential for the continuous proliferation of SCLC. While 85-90% of all human cancers are telomerase positive, SCLCs are nearly all telomerase positive¹, suggesting that telomerase targeting may be an effective strategy in the treatment of SCLC.

Key findings in the published paper include:

• Human and mouse SCLC lines are sensitive to THIO (6TdG) treatment in vitro and in vivo
• THIO decreases cancer initiating cells and diminishes tumor initiation potential in vitro and in vivo
• Low doses of THIO are effective in treating metastatic mouse SCLC tumors
• THIO activates type-I interferon pathway through cGAS-STING signaling
• THIO is highly effective in combination with ionizing radiation treatment regiments

“With few, if any, effective treatments for small cell lung cancer, there is a widespread need for innovative therapeutic strategies. The positive outcomes reported in our publication show THIO’s potential as a new therapeutic approach,” said Vlad Vitoc, M.D., MAIA’s Chairman and Chief Executive Officer. “THIO already holds Orphan Drug Designation for SCLC, underscoring the FDA’s recognition of THIO’s potential to improve outcomes for this highly lethal disease. With the positive preclinical and clinical data we have obtained to date for THIO, we have entered the Phase 2 planning stage for a clinical trial of THIO in SCLC along with two other cancers.”

Orphan Products Development grants orphan designation status to drugs and biologics that are intended for the treatment, diagnosis or prevention of rare diseases, or conditions that affect fewer than 200,000 people in the U.S. Orphan Drug Designation provides certain benefits, including financial incentives, to support clinical development and the potential for up to seven years of market exclusivity for the drug for the designated orphan indication in the U.S. if the drug is ultimately approved for its designated indication.

About the Publication

Nature Communications, volume 15, article number: 672 (2024), “A telomere-targeting drug depletes cancer initiating cells and promotes anti-tumor immunity in small cell lung cancer,” published 22 January 2024. Co-author disclosures included in manuscript.

About Small Cell Lung Cancer

Small cell lung cancer (SCLC) accounts for 13% of lung cancers. As the deadliest of all lung cancers, SCLC is one of the leading causes of cancer-related mortality in United States with 30,000 deaths annually. It is less common than non-small cell lung cancer (NSCLC), but is more aggressive and rapidly spreads (metastasizes) throughout the body.
