Safety and Efficacy Study of CC-122 Combined With Sorafenib for Primary Liver Cancer

Study Overview
=================
Brief Summary
-----------------
CC-122-HCC-001 is a Phase 1b dose escalation and expansion clinical study of CC-122 in combination with sorafenib for subjects with unresectable HCC who have received no prior systemic therapy for HCC. The dose escalation phase of the study will explore several dose levels of CC-122 in combination with sorafenib, followed by an expansion part of the study using the optimal combination dose regimen.

Detailed Description
-----------------
The primary objective of the study is to determine the safety and tolerability of CC-122 administered orally in combination with sorafenib, and to define the non-tolerated dose (NTD), the maximum tolerated dose (MTD), and the recommended phase 2 dose (RP2D). The secondary objective of the study is to determine the preliminary efficacy of CC-122 in combination with sorafenib, based on response Evaluation Criteria in Solid Tumors (RECIST 1.1)
