BRCAm subgroup (n=85):

  • Events, n (%): 14/47 (30) with LYNPARZA + abi/pred and 28/38 (74) with placebo + abi/pred

  • Median rPFS with LYNPARZA + abi/pred was not reached (95% CI: NR-NR) vs 8 months with placebo + abi/pred (95% CI: 6-15)

  • Results from the BICR assessment were consistent with the investigator-assessed rPFS results

  • BRCAm status was not a stratification factor in PROpel, and analysis was not controlled for Type 1 error

ITT population (n=796)

  • Statistically significant improvement in rPFS* was observed for LYNPARZA + abi/pred compared with placebo + abi/pred

Patients without an identified BRCAm (n=711)

  • Results from an exploratory analysis in this subgroup (HR=0.77 [95% CI: 0.63–0.96]) indicated that the improvement in the ITT population was primarily attributed to the results seen in the BRCAm subgroup

  • *rPFS assessed by investigator per RECIST v1.1 (soft tissue) and PCWG3 (bone) criteria.
  • NR=not reached.

  • Median OS with LYNPARZA + abi/pred was not reached (95% CI: NR-NR) vs 23 months with placebo + abi/pred (95% CI: 18-34)

  • BRCAm status was not a stratification factor in PROpel, and analysis was not controlled for Type 1 error

In PROpel, crossover from placebo to receive LYNPARZA + abi/pred was not allowed.

PROpel: Phase 3 trial

PROpel was a randomized, double-blind, placebo-controlled, multicenter, phase 3 trial1,2

LYNPARZA PROpel Study Design Chart LYNPARZA PROpel Study Design Chart

LYNPARZA was continued until objective radiological disease progression determined by investigator or unacceptable toxicity.

Patients were stratified by metastatic site and whether they received prior docetaxel at mHSPC stage. BRCAm was not a stratification factor. Prior abiraterone was not allowed.

BRCAm status was assessed after randomization and before primary analysis by both NGS-based tumor tissue and ctDNA tests. BRCAm classification criteria in line with the FDA-approved assays were used to determine the deleterious and suspected deleterious germline or somatic mutation status of patients.

  • *All patients received a GnRH analog or had prior bilateral orchiectomy.
  • Radiological progression-free survival (rPFS) assessed by investigator per RECIST v1.1 (soft tissue) and PCWG3 (bone) criteria.
