CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced plans to initiate a Phase 3 pivotal trial in 2025, named THIO-104, to evaluate the efficacy of THIO administered in sequence with a checkpoint inhibitor (CPI) in third-line non-small cell lung cancer (NSCLC) patients who are resistant to checkpoint inhibitors and chemotherapy. The multicenter, open-label, pivotal Phase 3 trial is designed to provide a direct comparison to chemotherapy in a 1:1 randomization of up to 300 patients.

“THIO has consistently and substantially outperformed standard treatment options in our THIO-101 Phase 2 trial to date. THIO-104 will give us direct comparative data from a randomized study in patients in third line of treatment,” said Vlad Vitoc, M.D., CEO of MAIA. “We expect that the results from this study will further illuminate THIO’s unmatched benefits for advanced stage NSCLC patients.

“Our initiation of THIO-104 will mark an important milestone along our goal for THIO’s FDA commercial approval,” Dr. Vitoc added.

MAIA expects to begin enrolling patients in THIO-104 in the second half of 2025 in select countries in Asia, Europe and in the U.S.

The primary endpoint of the clinical trial is overall survival for THIO sequenced with a CPI compared to investigator’s choice of chemotherapy in a third line setting. The secondary endpoints include disease control rate, overall response rate, duration of response, progression-free survival and safety.

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 third line of treatment for NSCLC for patients that are resistant to checkpoint inhibitors and chemotherapy.

• Expansion study to enroll patients in the U.S. and select countries in Europe and Asia
• Multiple milestones attainable for 2025

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 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.

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 THIO followed by cemiplimab (Libtayo) has been generally well-tolerated to date in a heavily pre-treated population.

• Median overall survival (OS) from THIO treatment extends to 16.9 months
• Newest data strengthens regulatory strategy

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 updated data from its THIO-101 pivotal Phase 2 clinical trial evaluating its lead clinical candidate, THIO, sequenced with Regeneron’s immune checkpoint inhibitor (CPI) cemiplimab (Libtayo^®) in patients with advanced non-small cell lung cancer (NSCLC) who failed two or more standard-of-care therapy regimens.

As of January 15, 2025, third line (3L) data showed median overall survival (OS) of 16.9 months for the 22 NSCLC patients who received at least one dose of THIO (the intent-to-treat population) in parts A and B of the trial. The analysis demonstrated 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. Studies of standard-of-care (SOC) chemotherapy treatments for NSCLC in a similar setting have shown OS of 5 to 6 months.²

“Treatment with THIO now shows a 99% probability that overall survival will extend past chemotherapy’s measure by a wide margin,” said Vlad Vitoc, M.D., CEO of MAIA. “THIO’s efficacy in advanced stages of NSCLC continues to exceed our expectations, especially in third-line treatment where the cancer is typically even more resistant to therapy. Our findings suggest great benefits to patients with unmet medical needs who see little hope for the future.

“With our latest overall survival results, our outlook for potential FDA commercial approval of THIO is stronger than ever,” Dr. Vitoc concluded.

Based on its regulatory strategy, MAIA believes there could be an opportunity for accelerated FDA approval of THIO depending on final results from the ongoing expansion of the THIO-101 trial.

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.

• Phase 2 pivotal trials to evaluate efficacy of THIO in combination with BeiGene’s checkpoint inhibitor (CPI) tislelizumab

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced that it has entered into a clinical supply agreement with global oncology company BeiGene to assess the efficacy of THIO, its small molecule telomere-targeting anticancer agent, in combination with BeiGene’s immune checkpoint inhibitor (CPI) tislelizumab in three cancer indications. The single arm pivotal Phase 2 trials will study the drug combination in hepatocellular carcinoma (HCC), small cell lung cancer (SCLC) and colorectal cancer (CRC).

MAIA’s preclinical results in HCC, with THIO in combination with a CPI, showed complete, durable and highly potent anti-tumor immune response. Preclinical results of THIO treatment in SCLC showed profound activation of innate and adaptive anti-tumor responses. In CRC pre-clinical studies, THIO administered in sequence with a CPI resulted in 100% complete response and anticancer immune memory was induced, resulting in no recurrence after rechallenge with 10x more CRC cells and no additional therapy. In all preclinical studies, THIO converted immunologically cold and non-responsive tumors into hot tumors that are responsive to a CPI.

“Based on excellent pre-clinical results, THIO was awarded orphan drug designation (ODD) for the treatment of both HCC and SCLC. Along with a third ODD in glioblastoma, the FDA has clearly recognized THIO’s potential as an effective treatment for multiple cancer indications. Comparatively, most oncology compounds at this stage of development have only one indication,” said MAIA Chairman and Chief Executive Officer Vlad Vitoc, M.D. “BeiGene’s tislelizumab has also demonstrated its potential to deliver clinically meaningful outcomes across a range of tumor types. We are pleased to partner with BeiGene for these important studies, two of which address the top three most lethal cancers worldwide.”

Under the terms of the collaboration, MAIA will sponsor and fund the planned clinical trials and BeiGene will provide tislelizumab. MAIA maintains global development and commercial rights to THIO and is free to develop the programs in combination with other agents and in other indications.

MAIA is targeting accelerated FDA approvals in each of the three indications to be studied along with non-small cell lung cancer (NSCLC), the focus of a current Phase 2 clinical trial of THIO with a CPI.

Market Trends

Hepatocellular carcinoma is the third most common cause of cancer-related deaths globally. The market for HCC was valued at $780 million in 2023 and is expected to increase to grow at a CAGR of 6.3% to $1.5 million by 2034.¹

Small cell lung cancer accounts for an estimated 15% of all lung cancer globally. The global SCLC therapeutics market is valued at approximately $6.5 billion in 2024 and is expanding at an estimated CAGR of 12.3% from 2024 to 2034.²

Colorectal cancer is the second leading cause of cancer-related deaths globally.³ Approximately 85% of all CRC cases are classified as microsatellite stable. MSS tumors are “cold tumors” that typically do not trigger the body’s immune system. The global CRC therapeutics market size was $9.26 billion in 2018 and is projected to reach $26.49 billion by 2032.⁴

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.

• Late breaking abstract to provide new updates from THIO-101 Phase 2 clinical trial in non-small cell lung cancer (NSCLC)
• Poster to highlight long-term therapeutic benefits of THIO sequenced with cemiplimab beyond treatment cessation

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announced that a late-breaking abstract (LBA) detailing new updates from its Phase 2 THIO-101 clinical trial was selected for oral and poster presentation at the 2024 Annual Meeting of the Society for Immunotherapy of Cancer (SITC), being held November 6-10, 2024, in Houston, Texas. The updates will include new data on efficacy and safety from its clinical trial evaluating THIO sequenced with Regeneron’s immune checkpoint inhibitor (CPI) cemiplimab (Libtayo®) in patients with advanced non-small cell lung cancer (NSCLC) who have failed two or more standard-of-care therapy regimens.

“We are honored to have our THIO-101 data recognized by SITC in a late-breaking abstract, a category reserved for research that has the potential to change medical practices. We believe that our latest data is compelling and further supports the ability of THIO to produce cancer cell specific immune memory and to remain active against cancer cells after extended periods of time,” said Vlad Vitoc, M.D., Chairman and CEO of MAIA. “Our findings to date are particularly significant for advanced-stage patients resistant to CPI and chemotherapy treatments who are in desperate need of new treatment options. In our opinion, the combination of THIO with a CPI is showing promise as a durable and effective NSCLC treatment.”

Presentation details:

Title:		Telomere-Targeting Agent THIO in Sequential Combination with Cemiplimab Demonstrates Long Term Therapeutic Benefits Beyond Treatment Cessation — A Phase 2 Trial in Advanced Immune Checkpoint Inhibitor Resistant Non-Small Cell Lung Cancer Patients
Abstract number:		1492
Session:		Late Breaking Abstract Session 1
Date:		Friday, November 8, 2024
Time:		11:45 a.m.-12:15 p.m. CST
MAIA Presenter:		Victor Zaporojan, M.D., Sr. Medical Director
Poster access:		MAIA’s poster will be available at maiabiotech.com/publications on November 8, 2024

According to SITC, a late-breaking abstract (LBA) submission is solely for abstracts with late-breaking data from interventional clinical trials in humans. The reference does not refer to abstracts that are submitted “late,” as in after submission deadlines.

As of August 1, 2024, 16 patients in the THIO-101 trial had survival follow-up surpassing 12 months, including 9 in third line treatment (3L). Interim median survival follow-up in 3L was 10.6 months. THIO’s substantial survival benefit in third line NSCLC surpasses current standard-of-care overall survival of 5.8 months.¹

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 Regeneron’s PD-1 inhibitor 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. For more information on this Phase II trial, please visit ClinicalTrials.gov using the identifier NCT05208944.
