Safety and Efficacy of LAG525 Single Agent and in Combination With PDR001 in Patients With Advanced Malignancies.

Study Overview
=================
Brief Summary
-----------------
This study was to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and anti-tumor activity of LAG525 as a single agent and in combination with PDR001 to adult patients with solid tumors. The study consists of a dose escalation (phase 1) to determine the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) for LAG525 as a single agent and in combination with PDR001, and a dose expansion (phase 2) which characterized treatment of LAG525 in combination with PDR001 at the MTD or RP2D.

Detailed Description
-----------------
This was a Phase 1/2, multi-center, open-label study comprising a Phase 1 dose escalation part followed by a Phase 2 dose expansion part. During the Phase 1 dose escalation part patients with any advanced solid tumor received the study treatment until the MTD was reached or a lower RP2D was established. The study had the following 3 dose escalation parts: 1) Single-agent LAG525; 2) Single-agent LAG525 in Japanese patients; 3) Combination of LAG525 with PDR001. Once the RP2D or MTD had been determined in the escalation parts, additional patients were to be enrolled in the Phase 2 expansion parts in order to assess the preliminary anti-tumor activity. Phase 2 expansion cohorts testing single-agent LAG525 were not opened for enrollment based on emerging data including but not limited to preliminary anti-tumor activity. Phase 2 expansion cohorts for the combination of LAG525 with PDR001 were opened and 5 tumor types were assessed: 1) Non-small cell lung cancer (NSCLC); 2) Melanoma; 3) Renal cell cancer (RCC); 4) Mesothelioma; 5) Triple negative breast cancer (TNBC). The efficacy and safety of the combination of LAG525 with PDR001 in these tumor types was assessed in both the PD-1/PD-L1 pre-treated and naïve settings.
