Placebo capsules for veliparib (120 mg) administered by mouth twice daily (BID) on Days -2 through 5 of a 21-day cycle. Carboplatin administered intravenously over approximately 15 to 30 minutes at AUC 6 mg/ml/min immediately following paclitaxel infusion on Day 1 of every cycle. Paclitaxel administered intravenously over approximately 1 hour at a dose of 80 mg/m² on Days 1, 8, and 15 of every cycle.

Veliparib capsules (120 mg) administered by mouth twice daily (BID) on Days -2 through 5 of a 21-day cycle. Carboplatin administered intravenously over approximately 15 to 30 minutes at AUC 6 mg/ml/min immediately following paclitaxel infusion on Day 1 of every cycle. Paclitaxel administered intravenously over approximately 1 hour at a dose of 80 mg/m² on Days 1, 8, and 15 of every cycle.

Supplied as 40 mg, 50 mg, or 100 mg capsules for oral administration twice daily (BID) on Days -2 through 5 of a 21-day cycle.

Veliparib Placebo

Administered intravenously over approximately 15 to 30 minutes at an area under the curve (AUC) of 6 mg/mL/min immediately following paclitaxel infusion on Day 1 of every cycle. The duration of carboplatin infusion may be lengthened according to institutional guidelines.

Administered by intravenous infusion over approximately 1 hour at a dose of 80 mg/m² of body-surface area (BSA) on Days 1, 8, and 15 of each 21-day cycle. Paclitaxel is to be infused prior to carboplatin on Day 1. Dosing of veliparib/placebo is to be completed before the carboplatin or paclitaxel infusions.

The primary objective of the study is to assess the progression-free survival (PFS) of veliparib in combination with carboplatin and paclitaxel (C/P) compared to placebo plus C/P in participants with a Breast Cancer Gene 1 or 2 (BRCA1; BRCA2) mutation in Human Epidermal Growth Factor Receptor 2 (HER2)-negative metastatic or locally advanced unresectable breast cancer. The secondary objectives of the study are to assess overall survival (OS), clinical benefit rate (CBR) through the end of Week 24, objective response rate (ORR) and PFS on subsequent therapy (PFS2) in participants treated with veliparib in combination with C/P versus placebo in combination with C/P.

This is a Phase 3, randomized, double-blind, multinational, multicenter study to evaluate the efficacy and tolerability of veliparib in combination with C/P compared to placebo in combination with C/P in participants with a BRCA1 or BRCA2 mutation, as documented by the Sponsor core laboratory, with HER2-negative metastatic or locally advanced unresectable breast cancer who received no more than 2 prior lines of cytotoxic therapy for metastatic disease. For the purposes of eligibility, HER2-negative status was based on the most recent tumor biopsy. Participants were randomized in a 2:1 ratio, with a total of approximately 500 participants planned to be randomized. Veliparib 120 mg/placebo twice a day (BID) was dosed Days -2 through 5 with carboplatin target area under the concentration-time curve (AUC) 6 administered on Day 1 and paclitaxel 80 mg/m2 administered weekly on Days 1, 8, and 15 of each 21-day cycle.

Safety and efficacy data through the prespecified primary analysis cutoff date of 05 April 2019 are included in the interim analysis.

AbbVie is committed to responsible data sharing regarding the clinical trials we sponsor. This includes access to anonymized, individual and trial-level data (analysis data sets), as well as other information (e.g., protocols and clinical study reports), as long as the trials are not part of an ongoing or planned regulatory submission. This includes requests for clinical trial data for unlicensed products and indications.

Time to PFS is defined as the number of days from the date the participant was randomized to the date the participant experiences radiographic disease progression (as determined by the investigators), or to the date of death (all causes of mortality) if disease progression is not reached. All events of disease progression occurring on or before the Primary Analysis Cutoff date of 05 April 2019 were to be included, regardless of whether the event occurred while the participant was still taking study drug or had previously discontinued study drug. PFS was estimated for each treatment group using Kaplan-Meier methodology.

Time to death (overall survival) is defined as the number of days from the date the participant was randomized to the date of the participant's death. All events of death which occur up to the analysis cutoff date are to be included, regardless of whether the event occurred while the participant was still taking study drug or after the participant discontinued study drug. If a participant has not died, the data for the participant is to be censored at the date last known to be alive or at the analysis cutoff date if that is earlier.

The final analysis of OS will occur when the pre-specified number of events has occurred in the ITT population.

The clinical benefit rate (CBR) for each treatment group was to be obtained from a time-to-event analysis of radiographic disease progression per the investigator. CBR is defined as the progression-free rate at 24 weeks (168 days), estimated for each treatment arm using Kaplan Meier methodology. All events of disease progression in the primary progression free survival analysis database were to be included, regardless of whether the event occurred while the participant was still taking, or had previously discontinued, study drug. If the participant had not yet progressed then their data was to be censored at the date of the last evaluable disease progression assessment. Participants without post-baseline assessments were to be censored at the date of randomization.

The final analysis of CBR will occur when the pre-specified number of Overall Survival events have occurred in the ITT population, per the fixed sequence testing procedure.

The objective response rate (ORR) is calculated as the percentage of participants who have a confirmed partial response (PR) or complete response (CR) based on assessment by the investigators per Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1. All participants who had at least one measurable lesion at baseline were to be included in the ORR calculation.

The final analysis of ORR will occur when the pre-specified number of Overall Survival events have occurred in the ITT population, per the fixed sequence testing procedure.

PFS2 is defined as the number of days from the date of randomization to the time of disease progression on subsequent therapy or death from any cause. The distribution of PFS2 was to be estimated for each treatment group using Kaplan-Meier methodology.

The final analysis of PFS2 will occur when the pre-specified number of Overall Survival events have occurred in the ITT population, per the fixed sequence testing procedure.

PFS was compared between the treatment groups using the log-rank test, stratified by prior platinum therapy (Yes versus No) and receptor status (estrogen receptor \[ER\] and/or progesterone receptor \[PgR\] positive versus ER/PgR negative).

A Cox proportional hazards model, stratified by prior platinum therapy (Yes versus No) and receptor status (estrogen receptor (ER) and/or progesterone receptor (PgR) positive versus ER/PgR negative) was used to estimate the hazard ratio and 95% confidence interval comparing the two treatment arms.
