Study Summary

This trial will explore if taking a one-month break from CDK4/6 inhibitor drug, abemaciclib, will make the body more sensitive to the drug and improve its effectiveness when used with fulvestrant.

Who is the study for?
This trial is for postmenopausal women over 18 with ER-positive, HER2-negative metastatic breast cancer that has worsened on a CDK4/6 inhibitor and an AI. Participants must be able to take oral meds, have no severe heart conditions or mental health issues affecting participation, not be pregnant or breastfeeding, and agree to use contraception during the trial.Check my eligibility
What is being tested?
The study tests if taking a one-month break from abemaciclib can make the body more responsive to it when used with fulvestrant afterward. Some participants will start directly on both drugs while others will have a run-in period with just fulvestrant before adding abemaciclib.See study design
What are the potential side effects?
Possible side effects include nausea, fatigue, low blood cell counts leading to increased infection risk or bleeding problems, liver issues indicated by abnormal blood tests, diarrhea, and potential allergic reactions to medication components.

Experimental Treatment
Group I: Fulvestrant plus Abemaciclib Arm with Fulvestrant Run-InExperimental Treatment1 Intervention
A 1-month (28 days) run-in of fulvestrant will precede fulvestrant plus abemaciclib treatment. Fulvestrant at a dose of 500 mg will be administered intramuscularly (IM) into the buttocks slowly (1-2 minutes per injection) as two 5-mL injections, one in each buttock, on Days 1 and 15 of the run-in period. After the fulvestrant run-in, fulvestrant plus abemaciclib will be administered in 28-day cycles until disease progression or unacceptable toxicity. Fulvestrant (500 mg IM) will be administered on Day 1 of each 28-day cycle. Abemaciclib at a dose of 150 mg will be given p.o. BID on Days 1-28 of each cycle
