• 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.

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 THIO followed by Regeneron’s 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.

• 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.”

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.

THIO’s favorable disease control and overall response rates exceed reported standard-of-care data in third line 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 new efficacy data from its Phase 2 THIO-101 clinical trial evaluating THIO sequenced with the immune checkpoint inhibitor (CPI) cemiplimab (Libtayo®) in patients with advanced non-small cell lung cancer (NSCLC) who failed 2 or more standard-of-care therapy regimens. Updated results show a favorable overall response rate (ORR) of 38% and a disease control rate (DCR) of 85% from THIO + CPI in third-line treatment. The new data was presented in a poster session at the American Society of Clinical Oncology (ASCO) 2024 Annual Meeting on June 3, 2024.

The primary objectives of THIO-101 Phase 2 trial are to examine the safety and tolerability of THIO as an anticancer drug and as an immune system primer, and to examine the clinical efficacy of THIO in the form of ORR. At the time of the most recent data cut-off (April 30, 2024), all evaluable patients had completed ≥1 post-baseline assessment.

Results from third-line treatment:

• Disease control rate (DCR) was 85% for THIO vs. standard of care DCR of 25–35% for chemotherapy¹
• 65% of patients crossed the 5.8-month overall survival (OS) threshold²
• 85% of patients crossed the 2.5-month progression-free survival (PFS) threshold^3-4
• Median survival follow-up time is currently 9.1 months (n=20)

Results from third-line treatment with THIO 180mg (optimal dose selection)

• Median PFS of 5.5 months (24.1 weeks)
• 78% OS rate at 6 months
• 38% ORR vs. standard of care 6–10% for chemotherapy²
• 75% of patients crossed the 5.8-month OS threshold²
• 88% of patients crossed the 2.5-month PFS threshold^3-4
• Median survival follow-up time is currently 9.1 months (n=8)

“All exceptional measures of efficacy in our trial to date have exceeded our own expectations and outperformed standard of care treatments,” said Vlad Vitoc, M.D., MAIA’s Chairman and Chief Executive Officer. “The data presented at ASCO advances THIO’s excellent clinical profile as a strong, safe, and highly effective alternative for patients who progressed following chemotherapy and other available treatments. We eagerly anticipate full efficacy data from THIO-101 in the second half of this year.”

To date, treatment with THIO + cemiplimab has been generally well tolerated in a heavily pre-treated patient population. Full enrollment in THIO-101 was completed on February 19, 2024, earlier than expected as per trial design. The Company expects that THIO-101 will be the first completed clinical study of a telomere targeting agent in the field of cancer drug discovery and treatment.

MAIA cautions that all statements, other than statements of historical facts contained in this press release, are forward-looking statements. Forward-looking statements are subject to known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels or activity, performance or achievements to be materially different from those anticipated by such statements. The use of words such as “may,” “might,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “intend,” “future,” “potential,” or “continue,” and other similar expressions are intended to identify forward looking statements. However, the absence of these words does not mean that statements are not forward-looking. For example, all statements we make regarding (i) the initiation, timing, cost, progress and results of our preclinical and clinical studies and our research and development programs, (ii) our ability to advance product candidates into, and successfully complete, clinical studies, (iii) the timing or likelihood of regulatory filings and approvals, (iv) our ability to develop, manufacture and commercialize our product candidates and to improve the manufacturing process, (v) the rate and degree of market acceptance of our product candidates, (vi) the size and growth potential of the markets for our product candidates and our ability to serve those markets, and (vii) our expectations regarding our ability to obtain and maintain intellectual property protection for our product candidates, are forward looking. All forward-looking statements are based on current estimates, assumptions and expectations by our management that, although we believe to be reasonable, are inherently uncertain. Any forward-looking statement expressing an expectation or belief as to future events is expressed in good faith and believed to be reasonable at the time such forward-looking statement is made. However, these statements are not guarantees of future events and are subject to risks and uncertainties and other factors beyond our control that may cause actual results to differ materially from those expressed in any forward-looking statement. Any forward-looking statement speaks only as of the date on which it was made.
