Overall survival (OS) was defined as the time from the date of randomization until the date of death. For those participants who did not die by the time the study was terminated and last patient, last visit occurred, OS was censored (+) on the last date the participant was known to be alive. OS is presented below in increasing monthly categories of survival. OS analysis was to be performed when a total of approximately 132 deaths were observed but due to the early termination of the study, statistical analyses were not performed.

All participants who received at least one dose of either study drug.

Due to study termination, the categories presented below are deaths occurring within 30 days of last dose and deaths occurring within 32 days of last dose. If the study had not been terminated early, the categories presented would have been 30 days and 90 days after last dose.

All participants who were randomized and treated with at least one dose of either study drug.

AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug. Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4= Potentially Life-threatening or disabling. Participants were evaluated from Day 1 (first day of treatment with study drug) to the date of the last participant, last visit of the study.

All participants who received at least one dose of study drug.
