TTD was defined as the time (in months) between initiation of second line sunitinib therapy and discontinuation of therapy for any reason including progression, death, and toxicity. Participants were censored at their date of last follow-up. As per response evaluation criteria in solid tumors (RECIST) 1.1 criteria: disease progression was at least a 20% increase in sum of diameters of target lesions, taking as a reference smallest sum on treatment, the sum must also demonstrate an absolute increase of at least 5 millimeter (mm), or the appearance of at least 1 new lesion.

PRIMARY outcome

Timeframe: From the date of initiation of second line sunitinib to the date of PR and CR or censored date, up to a maximum of approximately 5.5 years (from the data collected and observed retrospectively for approximately 4 months)

Population: Analysis population included all eligible participants whose data was collected and analyzed in this study.

The objective response rate was defined as the percentage of participants with partial response (PR) and complete response (CR). As per RECIST 1.1 criteria: CR = disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Disappearance of all non-target lesions and normalisation of tumour marker level. All lymph nodes must be non-pathological in size (\<10 mm short axis); PR = at least 30% decrease in sum of diameters of target lesions taking as reference baseline sum diameters.

Population: Analysis population included all eligible participants whose data was collected and analyzed in this study.

Progressive disease (PD) was defined as an increase in visible disease. According to RECIST 1.1; PD = at least a 20% increase in the sum of diameters of target lesions taking as reference the smallest sum on the study. This includes the baseline sum if that is the smallest on study. In addition to the relative increase of 20%, the sum also demonstrated an absolute increase of at least 5 mm or the appearance of at least 1 new lesion. Unequivocal progression of existing non-target lesions.

Stable disease was defined as no change in size of visible disease. According to RECIST 1.1, stable disease: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease , taking as reference the smallest sum diameters while on study; PD = at least a 20% increase in the sum of diameters of target lesions taking as reference the smallest sum on the study. This includes the baseline sum if that is the smallest on study. In addition to the relative increase of 20%, the sum also demonstrated an absolute increase of at least 5 mm or the appearance of at least 1 new lesion.
