Abstract 140O


In BROCADE3 (NCT02163694), addition of the PARP1/2 inhibitor veliparib (Vel) to carboplatin-paclitaxel (C-P) significantly prolonged progression-free survival (PFS) in patients (pts) with HER2-negative locally advanced/metastatic gBRCA-associated breast cancer (BC; hazard ratio=0.71 [95% CI 0.57, 0.88], P=.002). Here we report efficacy and safety in hormone receptor-positive (HR+) and triple-negative BC (TNBC) subgroups separately.


Pts with ≤2 prior lines of cytotoxic therapy for metastatic BC were randomized 2:1 to Vel (120 mg PO BID) + C-P or placebo (Pbo) + C-P. Vel-Pbo was given on days (d) –2 to 5, C (AUC 6 mg/mL/min IV) on d 1, and P (80 mg/m2 IV) on d 1, 8, and 15 (21-d cycles). Pts who discontinued C and P prior to progression (at investigator discretion) received blinded single-agent Vel or Pbo (300–400 mg BID) until progression. Primary endpoint was investigator-assessed PFS. Analysis of PFS in subgroups defined by hormone receptor status was preplanned. Analyses of PFS and overall survival (OS) were stratified by prior platinum status.


Among the 509 pts in the intent-to-treat population, 266 (52%) were HR+ and 243 (48%) had TNBC. PFS and OS results in each subgroup are presented in the table below. Adverse events (not related to progression) led to study drug discontinuation in 8.0%/3.3% of HR+ pts and 10.5%/7.5% of TNBC pts in the Vel + C-P and Pbo + C-P arms, respectively. Table: 140O

On the basis of stratified log-rank test. P values are nominal. BICR, blinded independent central review; C-P, carboplatin plus paclitaxel; ER, estrogen receptor; HR+, hormone receptor positive (ER and/or PgR); INV, investigator; m, median; NR, not reached; OS, overall survival; PFS, progression-free survival; PgR, progesterone receptor; TNBC, triple-negative breast cancer.


The addition of Vel to C-P improved PFS in gBRCA pts with HR+ BC and TNBC. In both subgroups, benefit of Vel was durable with an increase in proportion of pts progression free at 2 and 3 years compared with Pbo.
