• 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

• 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

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 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.

• 16 patients surpassed 12-month survival follow-up
• THIO’s substantial survival benefit in third line surpasses comparable standard-of-care overall survival of 5.8 months
• Median survival follow-up in third line was 10.6 months
• Treatment with THIO followed by Libtayo® has been generally well-tolerated to date

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announces favorable interim survival benefit from its lead clinical candidate THIO, a telomere-targeting treatment for patients with advanced non-small cell lung cancer (NSCLC). A Phase 2 clinical trial, THIO-101, is evaluating THIO sequenced with Regeneron’s immune checkpoint inhibitor (CPI) cemiplimab (Libtayo®) in patients with advanced NSCLC who failed two or more standard-of-care therapy regimens.

Published available results suggest that overall survival (OS) in third-line patients is 5.8 months.¹

As of August 01, 2024, 16 patients 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 is showing a survival benefit for patients with advanced NSCLC. As our follow-up continues, we have noted that three of the earliest patients enrolled are approaching 17-month survival. We’re on track to achieve our survival goals in third-line therapy,” said Vlad Vitoc, M.D., Chairman and Chief Executive Officer of MAIA. “THIO’s outperformance to date supports our thesis that our telomere targeting agent could become a treatment option for people suffering from advanced NSCLC.”

The 12-month survival data corresponds to the Company’s most recent data from THIO-101 demonstrating favorable disease control and overall response rates. As announced in April 2024, THIO 180mg + CPI in third-line treatment showed, in part, overall response rate (ORR) of 38%, disease control rate (DCR) of 88% and median progression-free survival (PFS) of 5.5 months.

MAIA expects to release full efficacy results of THIO-101 this year.

• THIO followed by cemiplimab shown to be well tolerated throughout trial, with far lower toxicity compared to standard of care treatments
• 6 patients on trial regimen for more than 12 months have completed up to 21 cycles, with treatment ongoing

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today announces positive treatment updates from its Phase 2 clinical trial, THIO-101, evaluating THIO sequenced with the 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.

The trial’s therapeutic regimen is cycled every 3 weeks, with THIO 180mg administered in 60mg incremental doses on days 1, 2 and 3, followed by immune activation on day 4 (no dosing), and cemiplimab 350mg administered on day 5. As of the latest clinical cutoff date, June 12, 2024:

• 6 patients remain on treatment following at least 12 months of therapy.
• Treatment with THIO followed by cemiplimab has been well tolerated throughout the trial, with much lower toxicity compared to standard-of care treatments.
• Continuing treatment past 12 months demonstrates safety, efficacy and ongoing benefit from MAIA’s novel telomere targeting NSCLC therapy.

“Our longest treated patient so far has completed 21 cycles of THIO sequenced with a CPI, and 6 patients who have crossed the 12-month survival follow-up are continuing the treatment,” said Vlad Vitoc, M.D., Chairman and Chief Executive Officer of MAIA. “With current therapies, second-line patients’ treatment duration is usually around 3-4 months¹ and third-line is even lower than that. It is very encouraging to see that our patients can remain on treatment for much longer. The ongoing benefits of THIO in longer-term patients are particularly notable, signifying THIO’s potential as a durable and efficacious treatment for advanced NSCLC patients faced with limited options.”

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.

FDA move illuminates key role of telomere targeting as a viable therapeutic strategy for cancer treatment

CHICAGO–(BUSINESS WIRE)– MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage company developing telomere-targeting immunotherapies for cancer, today announced the validation of clinical and regulatory pathways for viable therapies leveraging the cell’s telomeric functions as evidenced by the U.S. Food and Drug Administration (FDA) approval of imetelstat, a treatment for low- to intermediate-risk hematologic malignancies (myelodysplastic syndromes) from Geron Corporation.

“MAIA is one of the earliest pioneers of telomere targeting as a therapeutic strategy, and we share in the enthusiasm for the FDA approval of imetelstat for rare blood cancers originating in bone marrow. We have found that telomere targeting as a mechanism of action plays a key role in treating certain cancers, and we are studying this science in our Phase 2 trial of THIO in high-risk non-small cell lung cancer (NSCLC),” said Vlad Vitoc, M.D., Chairman and Chief Executive Officer of MAIA. “Our most recent clinical data shows THIO’s exceptional efficacy in checkpoint inhibitor and chemo-resistant patients in NSCLC. We salute Geron for validating the pathway,” concluded Dr. Vitoc.

Telomerase is present in over 85% of human cancers and contributes significantly to the proliferation and reproductive immortality of cancer cells. MAIA’s lead candidate is THIO, a telomere targeting agent in clinical development (Phase 2 THIO-101) to evaluate its activity in NSCLC. THIO is recognized by telomerase and incorporated into telomeres in cancer cells. Once incorporated, THIO compromises the telomere structure and function, leading to ‘uncapping’ of the chromosome ends and thus resulting in rapid tumor cell death.
