Conditions

Summary

Trial design: Phase II, prospective, multi-center, randomized, open label, parallel group study in patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with 2:1 randomization into Arm A (olaparib + elacestrant) or arm B (olaparib). Treatment in either arm will be given until disease progression, unacceptable toxicity, withdrawal of patient´s consent to study participation, or end of study. Trial population: Patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with an indication for standard-of-care PARP inhibitor therapy and planned treatment with olaparib, an ECOG performance status of 0-2 and life expectancy of \> 6 months, with normal bone marrow and kidney functions and no active or newly diagnosed central nervous system (CNS) metastases or symptomatic metastatic visceral disease at risk of life-threatening complications. Interventions: Patients randomized to Arm A will receive 600 mg olaparib daily and 400 mg elacestrant daily, while patients randomized to Arm B will receive 600 mg olaparib daily. Blood tests (hematology, biochemistry) will be performed at the beginning of every cycle, and imaging for tumor assessment (chest and abdominopelvic imaging) as well as QoL assessments will be performed every three months and in case of suspicion of progression/end of study.

Plain Language Summary

Simplified for easier understanding

This trial tests whether adding elacestrant (a hormone-blocking pill) to olaparib (a PARP inhibitor, a type of targeted therapy) is safe and effective for advanced breast cancer that is hormone receptor-positive and HER2-negative, and carries a BRCA gene mutation. **You may be eligible if...** - You have advanced or metastatic breast cancer that is HR-positive (hormone-driven) and HER2-negative - You carry a BRCA1 or BRCA2 gene mutation - You are already planned to receive olaparib as standard care - You are 18 or older, male or female - Your general health is reasonably good (ECOG 0–2) - You are willing to use effective non-hormonal contraception if you could become pregnant **You may NOT be eligible if...** - You have previously been treated with a PARP inhibitor (such as olaparib, niraparib, or rucaparib) - You have active or uncontrolled cancer spread to the brain - You are pregnant or breastfeeding - You have had a heart attack, severe heart failure, or stroke in the last 6 months - You have severe liver, kidney, or blood count problems - You are taking medications that strongly interact with the study drugs (e.g., certain antifungals or St. John's Wort) Talk to your doctor to see if this trial is right for you.
