Trial comparing treatments for Breast Cancer

Official title A Study Evaluating the Efficacy and Safety of Inavolisib Plus CDK4/6 Inhibitor and Letrozole vs Placebo + CDK4/6i and Letrozole in Participants With Endocrine-Sensitive PIK3CA-Mutated, Hormone Receptor-Positive, HER2-Negative Advanced Breast Cancer

ClinicalTrials.gov ID: NCT06790693

What this study is testing

What is Inavolisib?

This is an investigational oral medicine being studied as a potential treatment for advanced breast cancer. It is designed to block a specific protein called PI3K that helps cancer cells grow.

Also referred to as GDC-0077, Itovebi.

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
This study aims to find out if adding the drug inavolisib to standard treatments works better than standard treatments alone. It also checks for any safety issues.
Who it's for
The study is looking for people with advanced breast cancer that has specific hormone receptors and a PIK3CA gene mutation.
What's involved
Participants will take inavolisib or a placebo (a pill with no active drug) along with two other standard breast cancer medications.
Time commitment
The source text does not specify the total duration of the study or the required visit schedule.
  • Phase 3: a large, late-stage study
