Summary

This trial is testing a new drug, abemaciclib, in combination with bicalutamide for treating metastatic breast cancer that is positive for the androgen receptor and negative for HER2.

Who is the study for?
This trial is for adults with AR-positive, HER2-negative metastatic breast cancer who've recovered from prior chemotherapy and/or radiotherapy. Participants must have measurable disease, an ECOG status of 0-2, and a life expectancy over 12 weeks. Women must be postmenopausal or on ovarian ablation; men/women must agree to contraception. Exclusions include severe lung impairment, recent major surgery, brain metastases requiring steroids, uncontrolled diabetes or other serious medical conditions.
What is being tested?
The study tests Abemaciclib in combination with Bicalutamide for treating certain metastatic breast cancers. It's an open-label Phase IB/II trial where all participants receive the drugs without placebo control to assess effectiveness and safety.
What are the potential side effects?
Potential side effects may include digestive issues like nausea and vomiting, allergic reactions due to drug hypersensitivity, blood sugar level changes leading to diabetes symptoms, increased risk of infection due to bone marrow suppression affecting white blood cells.
