MAIA BIOTECHNOLOGY’s TelomerE-targeting Agent THIO, in combination with checkpoint inhibitor immune therapies Atezolizumab (ANTI-PD-L1) or PEMBROLIZUMAB (anti-PD-1), Demonstrated Significantly greater tumor inhibition

MAIA Intends to initiate its second Phase 2 go-to-market trial – THIO-102 - evaluating THIO with atezolizumab, pembrolizumab and other checkpoint inhibitors in multiple tumor types, including small cell lung cancer, liver cancer and colorectal cancer |
February 13, 2023, CHICAGO-- MAIA Biotechnology, Inc. (NYSE American: MAIA) announced today it intends to initiate its second Phase 2 go-to-market trial evaluating THIO, the world’s first telomere-targeting agent, in patients with four cancer indications. The FDA has awarded MAIA’s lead anti-cancer agent THIO two Orphan Drug Designations, based on the preclinical efficacy data, for liver (hepatocellular carcinoma) and small cell lung cancer models. The trial is designed to evaluate THIO in sequential combination with the immunotherapies pembrolizumab or atezolizumab, which are the most used checkpoint inhibitors in Oncology. A third immunotherapy checkpoint inhibitor could be added later such as nivolumab, durvalumab, dostarlimab, etc.
The trial previously demonstrated positive and encouraging preclinical results in colorectal, liver, and small cell lung cancer models.
Figure Legend:
THIO (6-thio-dG) is synergistic with anti-PD-1 agent pembrolizumab in Small Cell Lung Carcinoma (SCLC) in vivo in humanized murine cancer model.
Treatment with THIO sequentially followed by pembrolizumab results in highly potent anticancer effect, as compared to the effects of pembrolizumab alone.

THIO converts immunologically “cold” non-responsive SCLC tumor into “hot” and responsive to pembrolizumab.
Figure Legend:
THIO is highly synergistic and effective in combination with anti-PD-L1 agent atezolizumab and Ionizing Radiation (IR) in HCC53N cell-based model of Hepatocellular Carcinoma (HCC).
THIO in Colorectal Cancer (CRC) model
Figure Legend:
THIO (6-thio-dG) is highly synergistic and curative with anti-PD-L1 agent atezolizumab in MC 38 cell-based syngeneic model of Colorectal Cancer (CRC). Treatment with THIO sequentially followed by atezolizumab results in highly potent anticancer effect, as compared to the effects of atezolizumab alone. THIO administration converts immunologically “cold non-responsive” CRC tumor into “hot and responsive to anti-PD-L1 agent atezolizumab”.
Treatment with THIO in combination with IR and atezolizumab has shown results of complete regression of aggressive HCC tumors. At the same time, the combination of IR and atezolizumab is just partially efficacious.
“The THIO-102 trial is operationally on track to begin enrolling patients later this year,” said Mihail Obrocea, MD, MAIA’s Chief Medical Officer. “Based on the data generated on these indications, we are targeting accelerated approvals in these tumor types; in addition, we have now added a fourth arm which includes solid tumors of all types, that will serve as a signal generation arm; we will include telomerase positive breast, prostate, gastric, pancreatic, ovarian, along with potentially other tumor types.”

“These are patients that are facing very limited treatment options, usually chemotherapy with minimal efficacy and high toxicity,” said MAIA Chairman and Chief Executive Officer Vlad Vitoc, M.D. “THIO sequenced with an immune checkpoint inhibitor has demonstrated complete tumor regression in several cancer preclinical models. We believe that THIO can substantially improve on the limited clinical efficacy shown so far by atezolizumab, pembrolizumab and others. This go-to-market trial - THIO 102 - may provide THIO with more than 9 additional indications. Our existing trial with non-small cell lung cancer is another indication, potentially giving THIO more than 10 indications in total. Most oncology compounds at this stage of development have only one. We have 10 shots on goal!”
About THIO-102
THIO-102 is an upcoming multicenter, open-label, go-to-market Phase 2 trial designed to evaluate the safety and efficacy of THIO administered in sequence with anti-PD-1 or anti-PD-L1 in patients with telomerase (+) tumors. Following an innovative basket/umbrella design, the trial is comprised of four baskets: small cell lung cancer, liver, colorectal, and solid tumors all types. The first basket is in first line treatment of small cell lung cancer, where MAIA plans to evaluate THIO added to the current standard of care, EP + atezolizumab. In the remaining arms, MAIA plans to evaluate THIO in sequential combination with atezolizumab or pembrolizumab; the objective is to select the best combination by tumor type in Part A and expand into Part B that will include multiple Phase 2 pivotal arms seeking accelerated approvals.

About THIO
THIO is a telomere-targeting agent currently in clinical development to evaluate its activity in non-small cell lung cancer (NSCLC). Telomeres play a fundamental role in the survival of cancer cells and their resistance to current therapies. THIO is being developed as a second or higher line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.
About MAIA Biotechnology, Inc.
MAIA is a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer. The Company’s lead program is THIO, a potential first-in-class cancer telomere targeting agent in clinical development for the treatment of patients with telomerase-positive cancers.
