Brief Summary:
This is a Phase II, multicenter, open-label, randomized study to compare the efficacy of venetoclax in combination with fulvestrant compared with fulvestrant alone in women with ER+, HER2-negative, locally advanced or Metastatic Breast Cancer (MBC) who experienced disease recurrence or progression during or after treatment with CDK4/6i therapy for at least 8 weeks. As of 9th October 2020, participants in the Venetoclax + Fulvestrant arm, have all discontinued Venetoclax treatment and have continued on Fulvestrant treatment alone.

Experimental: Venetoclax + Fulvestrant
As of 9th October 2020, Participants in the Venetoclax + Fulvestrant arm, have all discontinued Venetoclax treatment and have continued on Fulvestrant treatment alone. Fulvestrant study treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, death, or predefined end of the study (2 years after the last participant is enrolled) which ever occur first.
|
Drug: Venetoclax
Venetoclax will be administered orally, 800-mg tablet beginning on Cycle 1 Day 1 until the 9th October 2020. Drug: Fulvestrant Fulvestrant will be administered orally, 500 mg administered as two 250-mg intramuscular (IM) injections on Cycle 1 Days 1 and 15 and on Day 1 of each subsequent 28-day cycle |
|
Active Comparator: Fulvestrant
Participants will receive fulvestrant administered as IM (intramuscular) injections. No crossover to the venetoclax arm is permitted. Study treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, death, or predefined end of the study (2 years after the last participant is enrolled) which ever occur first.
|
Drug: Fulvestrant
Fulvestrant will be administered orally, 500 mg administered as two 250-mg intramuscular (IM) injections on Cycle 1 Days 1 and 15 and on Day 1 of each subsequent 28-day cycle |
Primary Outcome Measures :
- Clinical benefit defined as Complete Response (CR), Partial Response (PR) or Stable Disease (SD) lasting >= 24 weeks, as determined by the Investigator according to RECIST v1.1 [ Time Frame: Randomization in participants with measurable disease at baseline through the end of study (2 years after the last participant is enrolled) ]
Secondary Outcome Measures :

- Objective Response (OR) [ Time Frame: Objective Response defined as Complete Response (CR) or Partial response (PR), as determined by the investigator according to RECIST v1.1 from Randomization of participant until end of the study (2 years after the last participant enrolled) ]
- Duration of Response (DOR) [ Time Frame: Time from first occurrence of a documented Objective response to the time of the first documented disease progression or death from any cause, whichever occurs first, until end of the study (2 years after the last participant is enrolled) ](as determined by the investigator according to RECIST v1.1)
- Overall Survival (OS) [ Time Frame: Randomization to death from any cause, through the end of study (2 years after the last participant is enrolled) ]
- Percentage of Participants with Adverse Events (AEs) [ Time Frame: Baseline to end of study (2 years after the last participant is enrolled) ]
- Plasma concentration of Venetoclax and fulvestrant [ Time Frame: At pre-defined intervals from Cycle 1, Day 1, through end of treatment (2 years after the last participant is enrolled). ]
- Mean changes from baseline scores in functional disease/treatment-related symptoms and global health status health-related quality of life (GHS/HRQoL) by cycle [ Time Frame: Baseline, cycle 1 day 1, and all subsequent cycles through at the end of treatment/discontinuation visit (2 years after the last participant is enrolled) ]Mean and mean changes will be assessed by the scales of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)
- Change in baseline pain score as assessed by the pain scale of EORTC QLQ-C30 [ Time Frame: Baseline through end of study (2 years after the last participant is enrolled) ]
- Baseline BCL-2 protein levels as measured by International Council for Harmonisation (IHC) correlating with clinical response measures [ Time Frame: Baseline through the end of study (2 years after the last participant is enrolled) ]
