Number of Participants Who Experienced an Adverse Event Primary · Up to approximately 2991 days, including 30 days after the last dose (through data cut-off date of 03 Apr 2017)

An adverse event is defined as any unintended or undesirable, noxious, or pathological change, compared to pre-existing conditions, experienced by a participant during a clinical study or the follow-up period, regardless of relationship to study drug. The number of participants who experienced an adverse event is presented.

Progression-free Survival (PFS) Secondary · Up to approximately 2961 days (through data cut-off date of 03 Apr 2017)

PFS was defined as the time from randomization to the first documented progressive disease (PD), or death due to any cause, whichever occurred first. Per Response Criteria in Solid Tumors version 1.1 (RECIST 1.1), PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Note: The appearance of one or more new lesions was also considered PD. The PFS for all participants is presented in days.
