CHICAGO--(BUSINESS WIRE)-- MAIA Biotechnology, Inc., (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer, today reported financial results for the first quarter ended March 31, 2023, and provided a corporate update.

“We are thrilled with the advancement of the THIO-101 trial, inclusive of reporting the positive topline data and preliminary survival data from the completed Part A safety lead-in of our ongoing phase 2 trial,” said Vlad Vitoc, M.D., MAIA’s Chairman and Chief Executive Officer. “The clinical activity seen with THIO thus far, in addition to its favorable safety and efficacy profiles, puts us one step closer to our goal of treating NSCLC and liver cancer. Additionally, we are proud to have strengthened our balance sheet by completing the follow-on offering. As we progress through the year, we look forward to our plan to share the safety data from Part B randomized efficacy/dose selection and receive IND clearance in the U.S.”

Corporate Highlights

Reported positive topline data from the completed Part A safety lead-in of the THIO-101 Phase 2 go-to-market trial in advanced Non-Small Cell Lung Cancer (NSCLC) and commenced recruitment in Part B randomized efficacy/dose selection: Topline data from Part A demonstrated that MAIA’s telomere-targeting agent, THIO, administered in sequential combination with Regeneron’s anti-PD-1 therapy, Libtayo® (cemiplimab), were generally well-tolerated.

Reported preliminary survival data in Part A of THIO-101 Phase 2 trial for Non-Small Cell Lung Cancer: As of April 2023, the first two patients enrolled in Part A continued to be alive, approximately 10 and 9 months, respectively, from treatment initiation. Both patients have advanced Stage IV metastatic disease and are heavily pretreated, receiving third and fourth line of therapy, respectively, after previously failing treatment with an immune checkpoint inhibitor.

Reported strong efficacy of THIO in liver in vivo cancer models: Study showed THIO with complete and durable responses in Hepatocellular Carcinoma (HCC), which is the dominant histology in primary liver cancer (90%). When combined with immunotherapy checkpoint inhibitor (CPI), the duration of response was further potentiated. Administration of THIO alone and in combination with CPI generated anti-cancer immune memory. Upon rechallenge with two times more cancer cells and no additional treatment, tumor growth was completely prevented.

Closed common stock public offering: Raised gross proceeds of approximately $5.75 million, before deducting underwriting discounts and offering expenses, in a public offering of 2,555,500 shares of common stock at a public offering price of $2.25 per share.

First Quarter 2023 Financial Results

Cash Position: The Company had cash totaling approximately $7.6 million as of March 31, 2023, compared to $10.9 million in cash as of March 31, 2022. The amount as of March 31, 2023 does not include the net proceeds from the public offering of shares of common stock received subsequent to quarter end.

Research and Development (R&D) Expenses: R&D expenses were approximately $2.2 million for the quarter ended March 31, 2023, compared to approximately $2.1 million for quarter ended March 31, 2022. The increase was primarily related to an increase in payroll and bonus expenses of approximately $0.46 million related to the increased headcount of additional research and development employees offset by a decrease in Clinical and Scientific research fees of approximately $0.23 million due less THIO-101 trial start-up fees, and a decrease in consulting and other fees of approximately $0.12 million. R&D expenses included approximately $0.3 million and $0.3 million of non-cash stock compensation expense in the first quarter of 2023 and 2022, respectively.

General and Administrative (G&A) Expenses: G&A expenses were approximately $2.0 million for the quarter ended March 31, 2023, compared to approximately $1.4 million for the quarter ended March 31, 2022. The increase for the quarter was primarily due to approximate increases in payroll and bonus expenses of $0.3 million, an increase of approximately $0.6 million of other expenses related to the costs of operating as a public company, offset by a decrease in stock-based compensation of approximately $0.2 million and professional fees of approximately $0.1 million. G&A expenses included approximately $0.3 million and $0.4 million of non-cash stock compensation expense in the quarters ended March 31, 2023, and 2022, respectively.

Other Income (Expense): Other income was approximately $0.07 million for the quarter ended March 31, 2023, and other expense for the quarter ended March 31, 2022 was approximately $0.03 million. The increase was primarily related to increases in the Australia research and development incentives of approximately $0.02 million and a gain on the change in the fair value of the warrant liability of approximately $0.02 million, offset by increases to interest expense of approximately $0.005 million.

Net Income (Loss): Net loss was approximately $4.1 million for the quarter ended March 31, 2023, as compared to net loss of approximately $3.9 million for the quarter ended March 31, 2022.

About THIO

THIO (6-thio-dG or 6-thio-2’-deoxyguanosine) is an 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. THIO is being 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.
