PIK3CA Mutations study: CGT6297
Official title A Study of Mutant Selective-Inhibitor (CGT6297), in Patients With Advanced Solid Tumors
ClinicalTrials.gov ID: NCT07383506
What this study is testing
What is CGT6297?
CGT6297 is an investigational oral medicine being studied for advanced solid tumors with PIK3CA mutations.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to see how safe and tolerable CGT6297 is, how it behaves in the body, and whether it can shrink tumors in patients with PIK3CA mutations.
- Who it's for
- Adults with advanced solid tumors, such as endometrial cancer or certain breast cancers, that have PIK3CA mutations.
- What's involved
- Participants will receive doses of CGT6297 and have regular blood tests, scans, and other safety checks to monitor the drug’s effects.
- Time commitment
- The study lasts several months, with multiple clinic visits for dosing and monitoring throughout the trial.
- Phase 1: an early, usually small safety study
- Which group you join is decided by chance.
