Summary

This trial will compare two treatments to find out which is better at prolonging progression-free survival in patients with advanced HER2-E and HR+/HER2- breast cancer.

Who is the study for?
This trial is for women with advanced HR+/HER2- breast cancer, specifically the HER2-E or Basal-like subtype. They must have a tumor block available for analysis, measurable disease by RECIST v1.1 standards, good blood and organ function, an ECOG status of 0 to 1, and be able to follow the trial procedures. Women who can become pregnant must use effective contraception and not have used CDK4/6 inhibitors or chemotherapy for advanced cancer before.
What is being tested?
The HARMONIA study is testing whether Ribociclib combined with endocrine therapy (Letrozole or Fulvestrant) works better than Palbociclib with the same endocrine therapy in extending progression-free survival in patients with advanced breast cancer within the HER2-E subtype. It's an open-label phase III trial enrolling about 456 patients worldwide.
What are the potential side effects?
Potential side effects include those common to cancer treatments such as fatigue, nausea, low blood counts leading to increased infection risk or bleeding problems, liver issues indicated by abnormal tests, hair loss from Paclitaxel and possible allergic reactions.
