Registered outcomes4

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
Primary
Number of Participants With Overall Response (OR), Defined as Those Participants Achieving Complete Response (CR) or Partial Response (PR), Assessed Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0 and Cutaneous Lesions
Baseline until disease progression/recurrence was documented, assessed for up to 66 weeks
RECIST-based response assessment was done at Weeks (Wks) 4 and 8 and every 8 weeks thereafter. Cutaneous disease assessment was done at Wk 4 and every 4 weeks thereafter. OR was evaluated when the skin and RECIST assessments coincided. Per RECIST, CR is the disappearance of all target and non-target lesions; PR is at least a 30 percent (%) decrease in the sum of the longest diameter (LD) of target lesions, taking as a reference the baseline sum LD. Cutaneous disease contained non-measurable and measurable skin disease, which was assessed by skin assessment tools.
SecondaryMedian Duration of Response,Defined as the First Documented Evidence of CR or PR Until the First Documentation of Disease ProgressionFrom the date of the first documented evidence of CR or PR until the date of the first documented disease progression or death, assessed for up to 62 weeks
RECIST-based response assessment was done at Wks 4 and 8 and every 8 weeks thereafter. Cutaneous disease assessment was done at Wk 4 and every 4 weeks thereafter. OR was evaluated when the skin and RECIST assessments coincided. Per RECIST, PD is \>=20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since treatment started or the appearance of \>=1 new lesion and/or unequivocal progression of existing non-target lesions. Cutaneous disease contained non-measurable and measurable skin disease, which was assessed by skin assessment tools.
Secondary
Progression-free Survival, Defined as the Interval Between the Date of Randomization and the Earliest Date of Disease Progression (PD) or Death Due to Any Cause (Defined by an Investigator Review of Lesions Based on RECIST and Cutaneous Disease)
From the date of the randomization until the earliest date of disease progression or death due to any cause, assessed for up to 66 weeks
RECIST-based response assessment was done at Wks 4 and 8 and every 8 weeks thereafter. Cutaneous disease assessment was done at Wk 4 and every 4 weeks thereafter. OR was evaluated when the skin and RECIST assessments coincided. Per RECIST, PD is \>=20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since treatment started or the appearance of \>=1 new lesion and/or unequivocal progression of existing non-target lesions. Cutaneous disease contained non-measurable and measurable skin disease, which was assessed by skin assessment tools.
SecondaryOverall SurvivalFrom the date of randomization until the date of death due to any cause, assessed for up to 163 weeksOverall survival is defined as the time from randomization until death due to any cause. For participants who did not die, time to death was censored at the time of last contact.
