Spots Global Cancer Trial Database for Phase III Palbociclib With Endocrine Therapy vs. Capecitabine in HR+/HER2- MBC With Resistance to Aromatase Inhibitors

Study Description

Brief Summary: This is an international (4 countries) randomized phase III study with 2 cohorts, patients will be randomized 1:1 to endocrine therapy (cohort 1: exemestane 25 mg daily, cohort 2: fulvestrant 500mg days 1 and 15 cycle 1 and then day 1 every 4 weeks) plus palbociclib (125 mg daily x3 weeks every 4 weeks) vs. capecitabine (1,250 mg/m2 twice daily x2 weeks every 3 weeks). Postmenopausal patients with HR+/HER2 MBC are eligible if resistant to previous nonsteroidal aromatase inhibitors (NSAI) (letrozole or anastrozole) in cohort 1 or previous aromatase inhibitors (AI) (letrozole, anastrozole or exemestane) in cohort 2 defined as: recurrence while on or within 12 months after the end of adjuvant treatment with NSAI/AI or progression while on or within 1 month after the end of treatment with NSAI/AI for MBC. Previous chemotherapy is permitted either in the (neo)adjuvant setting and/or as first line for MBC. Patients must have measurable disease according to RECIST 1.1 or bone lesions, lytic or mixed, in the absence of measurable disease.

Detailed Description: 296 patients have been randomized 1:1 between the experimental arm (Arm A: approximately 125 patients treated with palbociclib plus exemestane) and the control arm (Arm B: approximately 125 patients treated with capecitabine) before the approval of this protocol version (Cohort 1). Approximately 300 patients will be randomized 1:1 between the experimental arm (Arm A: approximately 150 patients treated with palbociclib plus fulvestrant) and the control arm (Arm B: approximately 150 patients treated with capecitabine) from the approval of this protocol version (Cohort 2).
