Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Progression-Free Survival (PFS) Rate

Outcome Description:

PFS was based on Kaplan-Meier estimates. PFS was defined as time in weeks from start of study treatment to first documentation of objective tumor progression or death due to any cause. PFS was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 7. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD]), or from death case report forms (CRFs). Percentage of participants who had not experienced progression or death by Week 16 is reported.

Outcome Time Frame:

Baseline up to Week 16
