Detailed description

This study GS-US-320-0110 is an international study planned to enroll participants in global countries, including China. However, due to the review timeline difference in China, full enrollment was reached in the main study (NCT01940471) before China was able to participate. Therefore, this registration only includes the China cohorts as they were not part of the main study analysis. Data for China cohorts were analyzed separately after the main study analysis was completed.
