Number of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR defined as disappearance of all target lesions. PR defined as a greater than or equal to 30 percent (≥30%) decrease in sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

Intent to Treat (ITT) population: all enrolled participants

The sum of participants with confirmed CR, PR, and stable disease (SD) greater than (>) 6 months according to RECIST. SD defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference smallest sum of longest dimensions since treatment started.

ITT

Number of participants with objective response based assessment of confirmed CR or PR of superficial lesions according to RECIST. Superficial lesions included skin lesions, chest wall lesions, and breast lesions and lymph nodes if followed up by physical examination.

ITT; Number of participants analyzed equaled (N =) participants who had superficial lesions with post baseline follow-up assessments of those lesions.

Time from date of randomization to date of first documentation of objective tumor progression or death due to any cause, whichever occurred first. PFS calculated as (Months)=(first event date minus randomization date plus 1) divided by 30.4.

ITT

Time from first objective documentation of complete or partial response that was subsequently confirmed to first documentation of disease progression or death due to any cause, whichever occurred first. DR calculated as (Weeks)=(end date for DR minus first subsequent confirmed CR or PR plus 1) divided by 7.

ITT; N=participants with objective response

Time from randomization to date of death due to any cause. OS (Months)=(death date minus date of first dose of study medication plus 1) divided by 30.4. For participants who were alive, overall survival was censored at last contact.

EORTC QLQ-C30: included functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting), and single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties). Most questions used 4-point scale (1 'Not at All' to 4 'Very Much'); 2 questions used 7-point scale (1 'Very Poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms. Change from baseline=Cycle/Day score minus baseline score.

ITT; N=participants who completed the scales at both baseline and any cycle; n=number of participants who completed the scales at both baseline and the respective cycle. Results reported for Cycles 1 through 6 only, because (n) decreased substantially after Cycle 6.

EORTC-QLQ-BR23: included functional scales (body image, sexual functioning, sexual enjoyment, and future perspective) and single item symptoms scales (systemic therapy side effects, breast symptoms, arm symptoms, and upset by hair loss). Questions used 4-point Likert scale (1 'Not at All' to 4 'Very Much'). Scores averaged and transformed to 0-100 scale. High score for functional scale=high/healthy level of functioning. High score for single item=high level of symptomatology/problems. Change from baseline=Cycle/Day score minus baseline score.
