Combination therapy provides promising results in patients with advanced non-small cell lung cancer

An early phase study testing an anti-PDL1 agent in combination with standard chemotherapy in the treatment of advanced non-small cell lung cancer has provided promising early results, prompting multiple phase III studies in lung cancer. The findings are being presented at the annual meeting of the American Society of Clinical Oncology (ASCO).

In this phase 1b study, patients with untreated non-small cell lung cancer received one of three standard platinum-based chemotherapy regimens (paclitaxel/carboplatin, pemetrexed/carboplatin or nab-paclitaxel/carboplatin) with MPDL3280A, an antibody targeting PD-L1. Early results from the

first 37 patients showed impressive response rates between 60-75 percent, comparing favorably to historical outcomes with chemotherapy alone, where historical response rates from randomized trials are around 30 - 35 percent. In addition, two complete responses already have been documented, with no evidence of lung cancer on CT scans.

"A complete response is not typically seen in patients with stage IV lung cancer," says the abstract's lead author, Stephen V. Liu, MD, assistant professor of medicine at Georgetown Lombardi Comprehensive Cancer Center. "And the response rates seen with MPDL3280A and chemotherapy were higher than one would expect with chemotherapy alone."
