Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Baseline and every cycle (4 weeks), for up to 6 cycles

Percentage of participants with objective response based on assessment of confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR was defined as complete disappearance of all target and non-target disease and no new lesions. PR was defined as ≥30% decrease under baseline of the sum of diameters of all target lesions.

Secondary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau)Cycle 5: 1 hour post-infusion on Day 1

The dosing interval was 1 cycle (4 weeks) in this study.

Maximum Observed Plasma Concentration (Cmax)Cycle 1 and Cycle 5: 1 hour post-infusion on Day 1
Plasma Concentration at End of Infusion (Cendinf)Cycle 1 Day 2 and Cycle 5 Day 1
Overall Survival (OS)Baseline and every 2 cycles (8 weeks), until death or up to 6 cycles after date of enrollment

Time in months from enrollment to death. For participants who are alive, overall survival was censored at the last contact.

Number of Participants With Positive Anti-Drug Antibody (ADA) TiterCycle 4 (predose on Day 1), 28 days after last dose (End-of-Treatment), and follow-up (approximately 150 days after last dose)

Number of participants with positive sample(s) in the ADA assay and in the neutralizing anti-drug antibodies (NAb) assay. An endpoint titer \<6.64 corresponded to negative ADA category value.

Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)Cycle 1 and Cycle 5: 1 hour post-infusion on Day 1

AUClast is the area under the plasma concentration time-curve from zero to the last measured concentration.

Progression-Free Survival (PFS)Baseline and every cycle (4 weeks), until progression or death

PFS was the time in months from start date to date of first documentation of progression, death due to any cause or symptomatic deterioration (global deterioration of health status requiring discontinuation of treatment).

Minimum Observed Plasma Trough Concentration (Cmin)Cycle 6: predose on Day 1

Cmin is the concentration at the end of treatment cycle (next cycle predose).
