WATERTOWN, Mass. and GOSSELIES, Belgium, March 06, 2024 (GLOBE NEWSWIRE) -- iTeos Therapeutics, Inc. (NASDAQ:ITOS), a clinical-stage biopharmaceutical company pioneering the discovery and development of a new generation of immuno-oncology therapeutics for patients, today reported financial results for the fourth quarter and full year ended December 31, 2023 and provided a business update.
"As we anticipate four clinical readouts across the portfolio, 2024 is poised to be a transformative year for iTeos," said Michel Detheux, Ph.D., president and chief executive officer of iTeos. "With the recent developments in the TIGIT field, we believe belrestotug is in an advantageous position and are excited for its future prospects. We look forward to sharing updates from our Phase 2 trials focused on 1L NSCLC and 1L HNSCC in 2024.

Fourth Quarter and Full Year 2023 Financial Results
- Cash and Investment Position: The Company's cash, cash equivalents, and investments position was $632.7 million as of December 31, 2023, as compared to $731.4 million as of December 31, 2022. The Company continues to expect its cash balance to provide runway through 2026.
- Research and Development (R&D) Expenses: R&D expenses were $27.9 million for the fourth quarter and $113.3 million for the year ended December 31, 2023, as compared to $25.4 million for the fourth quarter and $97.4 million for the year ended December 31, 2022. The increases in each comparative period were primarily due to increases in activities related to the belrestotug, inupadenant, and EOS-984 programs, and included the addition of new R&D employees hired to help advance these programs.
- General and Administrative (G&A) Expenses: G&A expenses were $12.4 million for the fourth quarter and $50.4 million for the year ended December 31, 2023, as compared to $11.1 million for the fourth quarter and $43.9 million for the year ended December 31, 2022. The increases were primarily due to increases in headcount and related costs and an increase in stock-based compensation compared to the prior year. The increases were partially offset by a decrease in recruiting costs.

About iTeos Therapeutics, Inc.
iTeos Therapeutics is a clinical-stage biopharmaceutical company pioneering the discovery and development of a new generation of immuno-oncology therapeutics for patients. iTeos Therapeutics leverages its deep understanding of tumor immunology and immunosuppressive pathways to design novel product candidates with the potential to restore the immune response against cancer. The Company's innovative pipeline includes three clinical-stage programs targeting novel, validated immuno-oncology pathways designed with optimized pharmacologic properties for improved clinical outcomes, including the TIGIT/CD226 axis and the adenosine pathway. iTeos Therapeutics is headquartered in Watertown, MA with a research center in Gosselies, Belgium.
About Belrestotug (EOS-448/ GSK4428859A)
Belrestotug is an Fc active human immunoglobulin G1, or IgG1, monoclonal antibody (mAb) targeting T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domains (TIGIT), an important inhibitory receptor which contributes to the suppression of innate immune responses against cancer. As an optimized high-affinity, potent anti-TIGIT mAb, belrestotug is designed to enhance the antitumor response through a multifaceted immune modulatory mechanism by engaging with TIGIT and FcγR, a key regulator of immune responses which induces cytokine release and antibody dependent cellular cytotoxicity (ADCC). The therapeutic candidate is progressing in multiple indications in collaboration with GSK.
About Inupadenant (EOS-850)
Inupadenant is a next-generation small molecule antagonist targeting adenosine A2A receptor (A2AR), the primary receptor on immune cells whose activation by adenosine suppresses innate and adaptive immune cell responses leading to inhibition of antitumor responses. Optimized for potency, high selectivity of A2AR, and activity at high adenosine concentrations in solid tumors, inupadenant is uniquely designed with its insurmountable profile to inhibit the ATP-adenosine pathway and has the potential for enhanced antitumor activity as compared to other A2AR antagonists in clinical development. The therapeutic candidate is in Phase 2 development.
About EOS-984
EOS-984 is a first-in-class small molecule targeting equilibrative nucleoside transporter 1 (ENT1) designed to inhibit the immunosuppressive activity of adenosine and restore immune cell proliferation. The therapeutic candidate has the potential to fully reverse the profound immunosuppressive action of adenosine on T and B cells and is in Phase 1 development.
