DARE Trial Summary

This trial is testing a new way to choose second-line adjuvant therapy for a certain type of breast cancer.

Who is the study for?
This trial is for men and women with stage II-III, HER2 negative, ER positive breast cancer who have been on hormone therapy for 6 months to 7 years. They must not show signs of cancer spread and agree to use contraception. Those with high recurrence risk or ctDNA positivity are eligible. Exclusions include intolerance to the drugs being tested, severe health issues, living outside the US, certain cancer histories, or taking specific medications.Check my eligibility
What is being tested?
The DARE trial tests if adding Palbociclib and Fulvestrant (second line adjuvant therapies) can benefit patients with a high residual risk of breast cancer after initial treatment. It's randomized: some will get standard care while others receive the new combination; decisions are made by chance.See study design
What are the potential side effects?
Palbociclib may cause low white blood cell counts leading to infection risk, fatigue, nausea, hair thinning and mouth sores. Fulvestrant can result in injection site pain, nausea and liver enzyme changes. Side effects vary among individuals.

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Surveillance/ctDNA screening Phase
Therapeutic Phase
Secondary outcome measures
Secondary Objective 1: Feasibility- correlation between clinically apparent metastatic or local disease and positive ctDNA result.
Secondary Objective 2: Efficacy- assess the ability of positive ctDNA results to predict clinical relapse.
Secondary Objective 3: Efficacy- assess whether ctDNA clearance is associated with improved relapse free survival and overall survival.
