Spots Global Cancer Trial Database for A Study Evaluating the Efficacy and Tolerability of Veliparib in Combination With Paclitaxel/Carboplatin-Based Chemoradiotherapy Followed by Veliparib and Paclitaxel/Carboplatin Consolidation in Adults With Stage III Non-Small Cell Lung Cancer (NSCLC)

Study Description

Brief Summary: This study seeks to establish * the recommended Phase 2 dose (RPTD) of veliparib in combination with concurrent paclitaxel/carboplatin-based chemoradiotherapy (CRT) and consolidation with paclitaxel/carboplatin-based chemotherapy (Phase 1 portion), and * to assess whether the addition of oral veliparib versus placebo to paclitaxel/carboplatin-based chemoradiotherapy with paclitaxel/carboplatin consolidation will improve progression-free survival (PFS) in adults with Stage III non-small cell lung cancer (Phase 2 portion). A strategy decision was made not to proceed to Phase 2 portion of this study due to change in standard of care.

Detailed Description: This was to be a 2-phase study consisting of 1. A Phase 1, dose escalation study of veliparib to determine a RPTD for combination with concurrent paclitaxel/carboplatin-based CRT and paclitaxel/carboplatin-based consolidation chemotherapy; followed by 2. A Phase 2, randomized, double-blinded study to determine whether veliparib improved outcome relative to placebo when added to paclitaxel/carboplatin based CRT followed by consolidation paclitaxel/carboplatin in adults with previously untreated Stage III NSCLC. In the dose escalation phase (Phase 1) of the study participants will be assigned to ascending doses of veliparib in combination with carboplatin, paclitaxel, and thoracic radiotherapy for 7 weeks following a traditional "3 + 3" design. The first cohort of at least 3 - 6 participants will receive veliparib 60 mg twice a day (BID) throughout CRT. Dose limiting toxicity (DLT) events will be collected for each dosing cohort until a new dosing cohort is opened or until the RPTD is identified. Participants will also receive a consolidation dose of veliparib of 120 mg BID + carboplatin and paclitaxel for up to two 21-day cycles. Once the concurrent CRT RPTD is identified, an additional cohort will be enrolled to explore the tolerability of a consolidation dose of veliparib at 240 mg BID + carboplatin + paclitaxel for up to two 21-day cycles. Following the dose escalation portion of the study, the RPTD will be determined by the sponsor and the Phase 2 portion of the study will begin with patient randomization in a 1:1:1 ratio to concurrent paclitaxel/carboplatin/radiotherapy/veliparib followed by consolidation paclitaxel/carboplatin/veliparib, concurrent paclitaxel/carboplatin/radiotherapy/veliparib followed by consolidation paclitaxel/carboplatin/placebo, or concurrent paclitaxel/carboplatin/radiotherapy/placebo followed by consolidation paclitaxel/carboplatin/placebo. Randomization will be stratified by tumor volume (≤ 90 versus \> 90 cm³) and smoking history (current smoker versus former smoker versus never smoked). Phase 2 was not carried out since during the study there was a change in standard of care for patients with newly diagnosed, unresectable Stage III NSCLC.
