WATERTOWN, Mass. and GOSSELIES, Belgium, Aug. 08, 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 second quarter ended June 30, 2024 and provided a business update.
“Our achievements and pipeline progress this year, specifically the positive interim assessment data from the Phase 2 GALAXIES Lung-201 study which supported the launch of the Phase 3 GALAXIES Lung-301 study, demonstrate significant momentum for iTeos. Our conviction in the potential of the belrestotug and dostarlimab doublet only continues to grow,” said Michel Detheux, Ph.D., president and chief executive officer of iTeos. “Furthermore, we are very excited to be approaching data readouts for both adenosine programs – inupadenant and EOS-984. As we continue to build on this impressive foundation, we are enthusiastic about our growing pipeline and the opportunities that lie ahead in the catalyst-rich second half of the year.”

Second Quarter 2024 Financial Results
- Cash and Investment Position: The Company’s cash, cash equivalents, and investments position was $679.4 million as of June 30, 2024, as compared to $677.5 million as of June 30, 2023. Pro forma cash, cash equivalents, and investments position were $714.4 million as of June 30, 2024, inclusive of a $35.0 million unbilled milestone receivable relating to the dosing of the first patient in the GALAXIES Lung-301 clinical trial. The Company expects its cash balance to provide runway through 2027, which includes the potential initiation of multiple Phase 3 registrational trials assessing the belrestotug + dostarlimab doublet.

- Research and Development (R&D) Expenses: R&D expenses were $36.7 million and $71.2 million for the quarter and six months ended June 30, 2024, respectively, as compared to $29.2 million and $54.9 million for the same quarter and same six months of 2023, respectively. The increase compared to the comparative period was 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 $12.5 million and $25.2 million for the quarter and six months ended June 30, 2024, respectively, as compared to $13.4 million and $25.4 million for the same quarter and same six months of 2023, respectively. The decrease was primarily due to decreases in professional fees and expenses, commercial-related expenses, and various other general and administrative expenses. These were partially offset by an increase in compensation expenses for G&A employees.
- Net Income/Loss: Net loss was $7.1 million, or net loss of $0.18 per basic and diluted share for the quarter ended June 30, 2024, as compared to a net loss of $34.3 million, or a net loss of $0.96 per basic and diluted share for the quarter ended June 30, 2023. Net loss was $45.3 million, or net loss of $1.20 per basic and diluted share for the six months ended June 30, 2024, as compared to a net loss of $49.9 million, or a net loss of $1.39 per basic and diluted share for the six months ended June 30, 2023.
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 immunosuppressive 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 potential 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.
