Recruiting studies
- NCT05524584RecruitingPhase 2
Anastrozole, fulvestrant, and abemaciclib for hormone-positive breast cancer

La Jolla, CaliforniaAges 18 years+ - NCT07347600Recruiting
Studying inavolisib for a type of advanced breast cancer
This study tests a targeted therapy called inavolisib for people whose breast cancer has spread (advanced or metastatic), is hormone receptor-positive and HER2-negative, has a PIK3CA mutation, and has stopped responding to hormone therapy. It aims to see if inavolisib is safe and works well for them.

Common questions
- Are there clinical trials for her2-negative?
- Yes. Clin2 currently lists 154 recruiting her2-negative studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a her2-negative trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a her2-negative trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
