TTP = (first date of tumor progression - date of enrollment + 1). Progressive disease: ≥20% increase in sum LD of target lesions from smallest sum LD recorded since treatment start or appearance of ≥1 new lesions.
Baseline, every 2 cycles (each cycle=21 days) until disease progression or participant discontinuation; maximum follow-up was from baseline up to 12 cycles
