Study of 2 Ribociclib Doses in Combination With Aromatase Inhibitors in Women With HR+, HER2- Advanced Breast Cancer — AMALEE

Breast Cancer Clinical Trial

Official title:
A Phase II, Multicenter, Randomized, Open-label Study to Evaluate the Safety and Efficacy of 400 mg of Ribociclib in Combination With Non-steroidal Aromatase Inhibitors for the Treatment of Pre- and Postmenopausal Women With Hormone Receptor-positive, HER2-negative Advanced Breast Cancer Who Received no Prior Therapy for Advanced Disease

Status Active, not recruiting

Clinical Trial Summary

QT interval prolongation and neutropenia are considered to be important identified risks for ribociclib. The approved dosing regimen of ribociclib is 600 mg daily (QD) on a 3 weeks on/1 week off schedule. The purpose of the study is to explore whether a reduced dosing regimen of 400 mg ribociclib orally QD 3 weeks on/1 week off may decrease the risk of QTc prolongation without compromising the efficacy of ribociclib in combination with a non-steroidal aromatase inhibitor (NSAI) in pre- and postmenopausal women with hormone receptor-positive (HR-positive), HER2-negative advanced breast cancer (aBC) who have not received prior therapy for advanced disease.

Clinical Trial Description

This is a phase II, multicenter, randomized, open-label study to evaluate the safety and efficacy of a reduced ribociclib dose of 400 mg in combination with an NSAI (letrozole or anastrozole) for the treatment of pre- and postmenopausal women with HR-positive, HER2-negative aBC who have received no prior therapy for advanced disease. Patients will be randomly assigned to one of the below treatment arms in a 1:1 ratio: - Experimental arm - Ribociclib 400 mg QD 3 weeks on/1 week off + NSAI (+ goserelin in premenopausal women) - Control arm - Ribociclib 600 mg QD 3 weeks on/1 week off + NSAI (+ goserelin in premenopausal women). Participants will receive study treatment until disease progression (radiologically documented according to RECIST 1.1 criteria), unacceptable toxicity, death, or discontinuation from the study treatment for any other reason. Continuation of study treatment beyond initial disease progression (RECIST 1.1) will not be allowed. For participants who discontinue treatment for reasons other than documented disease progression, death, lost to follow-up, or withdrawal of consent, tumor assessments must continue to be performed until disease progression, death, lost to follow-up, or withdrawal of consent (post-treatment efficacy follow-up). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
