Summary

This phase I/II partially randomized trial studies the side effects and best dose of veliparib when given together with radiation therapy, carboplatin, and paclitaxel and to see how well it works in treating patients with stage III non-small cell lung cancer that cannot be removed by surgery. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether radiation therapy, carboplatin, and paclitaxel are more effective with or without veliparib in treating non-small cell lung cancer.

Detailed description

PRIMARY OBJECTIVES: I. To establish the maximum tolerated dose (MTD) and the recommended phase II dose of ABT-888 (veliparib) when given concurrently with standard carboplatin/paclitaxel and radiotherapy in patients with unresectable stage III non-small cell lung cancer (NSCLC). (Phase I) II. To assess whether carboplatin/paclitaxel plus ABT-888 compared with carboplatin/paclitaxel plus placebo improves progression-free survival (PFS) in patients with unresectable stage III NSCLC. (Phase II) III. To compare overall survival (OS) in patients treated with carboplatin/paclitaxel and radiotherapy plus ABT-888 to those treated with carboplatin, paclitaxel and radiotherapy plus placebo. (Phase II) IV. To assess the response rate (confirmed and unconfirmed, complete and partial responses) and disease control rate in the subset of patients with measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. (Phase II) V. To assess the safety and toxicity profile of the regimen. (Phase II) SECONDARY OBJECTIVES: I. To collect tumor tissue from pretreatment biopsies (archival samples) for biomarker studies, including poly (ADP-ribose) polymerase 1 (PARP) activity by measuring the levels of poly-ADP-ribose, gamma-H2A histone family, member X (gamma-H2AX), and messenger ribonucleic acid (mRNA) expression levels of deoxyribonucleic acid (DNA) repair enzymes such as excision repair cross-complementing rodent repair deficiency, complementation group 1 (ERCC1)/x-ray repair complementing defective repair in Chinese hamster cells 1 (XRCC1). II. To collect blood samples for evaluation of gamma-H2AX (circulating tumor cells) and other relevant future studies. OUTLINE: This is a phase I, dose-escalation study of veliparib followed by a randomized phase II study. PHASE I: INDUCTION THERAPY: Patients undergo 3-dimensional conformal radiation therapy (3D-CRT) once daily (QD), 5 days a week, for 6 weeks. Patients also receive veliparib orally (PO) twice daily (BID) on days 1-43 and carboplatin intravenously (IV) over 30 minutes and paclitaxel IV over 1 hour on days 1, 8, 15, 22, 36, and 43 in the absence of disease progression or unacceptable toxicity. Patients without disease progression after completion of chemoradiotherapy undergo consolidation therapy. CONSOLIDATION THERAPY: Beginning within 4-6 weeks of chemotherapy and radiation therapy, patients receive veliparib PO BID on days 1-7 (course 1) and 22-28 (course 2) and carboplatin IV over 30 minutes and paclitaxel IV over 3 hours on day 1 and on day 22 of course 2. Treatment repeats every 21 days for 2 courses in the absence of disease progression or unacceptable toxicity. PHASE II: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients undergo 3D-CRT and receive veliparib, carboplatin, and paclitaxel as in Phase I induction and consolidation therapy. ARM II: Patients undergo 3D-CRT as in arm I. Patients also receive placebo PO BID on days 1-43 and carboplatin and paclitaxel as in Phase I. Within 4-6 weeks after completion of chemotherapy and radiation therapy, patients receive placebo on days 1-7 and carboplatin and paclitaxel as in Phase I. After completion of study treatment, patients are followed up every 4 months for first 2 years and then every 6 months until 5 years.
