This study is testing a new drug called RLY-2608, which targets a specific gene mutation called PIK3CA. This mutation can cause overgrowth and other problems in the body. The study has three parts: the first part finds the right dose; the second part examines different groups of people to see how they respond; and the third part compares the drug to a placebo (a pill with no medicine).
Key Points:
- Participants should be diagnosed with a condition related to the PIK3CA mutation.
- Some medical history or conditions may exclude you from participating.
- Participation may involve providing tissue samples or blood for testing.
To join, you must have a PIK3CA mutation or similar issues, and be willing to provide tissue samples if needed. You can’t join if you have had certain treatments recently or have heart issues.
