Trials are underway to assess benefit of veliparib combination therapies in NSCLC. A phase II study reported preliminary activity with veliparib compared with placebo in combination with carboplatin and paclitaxel as first-line treatment, although the modest difference in progression-free survival did not reach statistical significance [1]. A larger phase III trial (NCT02106546) is now underway to try to show progression-free survival benefit of first-line combination veliparib versus placebo with carboplatin and paclitaxel in a larger cohort of advanced or metastatic NSCLC patients.
Veliparib in combination with whole brain radiation therapy has also been studied in patients with brain metastases in NSCLC in a phase II trial (NCT01657799), but there was no significant survival improvement versus placebo [2].
