Anti-PD-L1 therapy shows promise in early NSCLC trials

Pharmacokinetic studies of MEDI-4736 indicate a dose-dependent increase in target engagement, consistent with binding of the agent to PD-L1. Initial clinical data on eight patients demonstrated response at all different dose levels, ranging from 42% to 80%. "This involves small subsets of patients, so hopefully we’ll see more data on this agent in the next couple of years," Dr. Horn said.

The final anti-PD-L1 in clinical development is MSB0010718C from EMD Serono, but no data are available yet. A three-dose escalation study up to 10 mg/kg is underway. "Hopefully, we’ll see some data on this later this year," Dr. Horn said.

Dr. Horn disclosed that she is a speaker for Bristol-Myers Squibb, Theradex, and other companies.
