It is in Phase 1 clinical development for the treatment of solid tumors, including neoplasms and colorectal cancer. It is not yet approved for any indication and remains under study in a single recruiting trial.

What is GSK5460025 used for?

GSK5460025 is being studied for the treatment of solid tumors, specifically neoplasms and colorectal cancer. It is an investigational therapy in Phase 1 development, so it is not approved for any use. The ongoing trial enrolls adults aged 18 years and older with these tumor types.

Who makes GSK5460025?

GSK5460025 is developed by GSK plc, which trades under the ticker GSK. The company is the sponsor of the Phase 1 trial evaluating the drug in solid tumors, including colorectal cancer, across sites in the United States, Canada, Europe, and Japan.

What phase is GSK5460025 in?

GSK5460025 is in Phase 1 clinical development. It is an investigational small molecule and has not been approved by the FDA or any other regulatory agency. The single Phase 1 trial is currently recruiting participants with solid tumors, including colorectal cancer.

What clinical trials is GSK5460025 in?

GSK5460025 is being evaluated in one Phase 1 trial, NCT07213609, titled a study to investigate the safety and preliminary efficacy of GSK5460025 alone or in combination with other anti-cancer agents in participants with solid tumors. The trial is recruiting, with an estimated enrollment of 47 participants across nine countries.

Is GSK5460025 biomarker selected?

Yes, the GSK5460025 Phase 1 trial NCT07213609 is biomarker selected, meaning enrollment is guided by a biomarker. The study is a controlled, non-randomized, open-label trial evaluating the drug alone or in combination with other anti-cancer agents in adults with solid tumors, including colorectal cancer.
