Compugen Advances Cancer Research with First Patient Dosed in Clinical Trial for COM503 and Zimberelimab

In a groundbreaking development, Compugen Ltd., a trailblazer in immunotherapy and computational target discovery, has announced the initiation of a Phase 1 clinical trial involving the dosing of the first patient with COM503. This novel antibody targets the IL-18 binding protein and is being evaluated both as a monotherapy and in combination with Zimberelimab, another immunotherapy developed by Gilead Sciences. This clinical trial marks a significant step forward in addressing advanced solid tumors, providing hope for improved cancer therapies.

The trial aims to explore the efficacy, safety, and pharmacokinetics of COM503. According to Dr. Anat Cohen-Dayag, President and CEO of Compugen, the launch of this trial represents a unique opportunity in cancer treatment by leveraging the biological properties of cytokines, particularly IL-18. Research indicates that tumor cells in patients with certain cancers often produce high levels of IL-18; however, these levels are typically inhibited by an endogenous binding protein, limiting their therapeutic effects. COM503 has the potential to inhibit this binding protein, allowing IL-18 to act more effectively within the tumor microenvironment, thereby enhancing anti-tumor immune responses.

Compugen's collaboration with Gilead entered into a licensing agreement in December 2023, solidifying the pathway for COM503's development. Under this agreement, Gilead has exclusive rights to bring this promising treatment through clinical stages and into commercialization, having already invested upfront and milestone payments amounting to a remarkable $90 million, with further potential earnings exceeding $758 million.

The clinical trial is structured as a multi-center dose escalation and expansion study, with a primary focus on determining the maximum tolerated dose. Dr. Manish Sharma from the START Center for Cancer Research in Michigan expressed excitement over offering a new investigational treatment that could provide unique therapeutic options for cancer patients. The trial’s design emphasizes swift patient enrollment, a critical factor in demonstrating the safety and pharmacokinetics of COM503.

This focus on precision medicine is aligned with Compugen’s broader mission, utilizing its proprietary Unigen™ discovery engine, which leverages advanced computational methods to identify new therapeutic targets. Alongside COM503, Compugen's pipeline includes additional candidates such as COM701 targeting PVRIG and COM902 aimed at TIGIT, showcasing the company’s commitment to innovative cancer therapies.

The significance of COM503 lies not just in its potential efficacy but also in its pioneering approach to immuno-oncology. As the trial progresses, the hope is that it will lead to breakthroughs in treating advanced solid tumors, especially for patients who have limited options available.

The implications of this trial extend beyond immediate patient care; they also represent a critical advancement in understanding cytokine biology in cancer therapy. As expectations grow regarding the outcomes of the trial, the medical community will be keenly observing how this research translates into clinical benefits for cancer patients worldwide. Scheduled to unfold over the coming months, the Phase 1 trial will illuminate new pathways in oncological treatments, leveraging the power of targeted immunotherapy to address one of the most pressing challenges in medical science today.
