A Phase 1/2 Study to Evaluate MEDI4736

Study Overview
=================
Brief Summary
-----------------
This is a multicenter, open-label, first-time-in-human study with a standard 3+3 dose-escalation phase in participants with advanced solid tumors followed by an expansion phase in participants with advanced solid tumors. An exploration cohort has been added to determine the safety using every 4 weeks (Q4W) dosing.

Detailed Description
-----------------
A dose-escalation and dose-expansion study of MEDI4736 (a monoclonal antibody that targets programmed cell death ligand-1 (PD-L1)) will evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity (IM), and antitumor activity of MEDI4736 in adult participants with solid tumors. A dose exploration cohort will look at the safety profile of Q4W dosing of MEDI4736.
