Compares treatment options for Metastatic Breast Cancer
Official title A Study to Evaluate the Efficacy and Safety of Inavolisib in Combination With Phesgo Versus Placebo in Combination With Phesgo in Participants With PIK3CA-Mutated HER2-Positive Locally Advanced or Metastatic Breast Cancer
ClinicalTrials.gov ID: NCT05894239
What this study is testing
What is Inavolisib?
Inavolisib is an investigational medicine, given as an once-daily injection under the skin, being studied as a potential treatment for metastatic breast cancer.
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 will evaluate the efficacy and safety of inavolisib in combination with Phesgo (pertuzumab, trastuzumab, and rHuPH20 injection for subcutaneous use) compared with placebo in combination with Phesgo, as maintenance therapy, after induction therapy in participants with previously untreated HER2-positive advanced breast cancer (ABC).
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug.
