What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment-Related Adverse Events	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.).	MAX 2 Years
Objective Response Rate	Percentage 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). The result was presented along with the corresponding exact 2-sided 95% confidence interval (CI).	MAX 2 Years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rates by KIT Expression Status	Percentage of participants with objective response based assessment of CR or confirmed PR according to RECIST. Objective response rates by KIT expression status were calculated according to RECIST and were presented along with the corresponding exact 2-sided 95% CIs.	MAX 2 Years
Objective Response Rates by c-Kit Mutation Status	Percentage of participants with objective response based assessment of CR or confirmed PR according to RECIST. Objective response rates by c-kit mutation status were calculated according to RECIST and were presented along with the corresponding exact 2-sided 95% CIs.	MAX 2 Years
Objective Response Rates by Platelet - Derived Growth Factor Receptor Alpha (PDGFRα) Mutation Status	Percentage of participants with objective response based assessment of CR or confirmed PR according to RECIST. Objective response rates by PDGFRα mutation status were calculated according to RECIST and were presented along with the corresponding exact 2-sided 95% CIs.	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events in Elderly Population	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). Elderly population was defined as the participants who aged 65 or older.	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Who Had Hepatic Impairment	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). Hepatic impairment referred not to transient laboratory test value abnormalities, but to the events that were clinically noteworthy and required follow-up.	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Who Had Renal Impairment	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). Renal impairment referred not to transient laboratory test value abnormalities, but to the events that were clinically noteworthy and required follow-up.	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Who Used Concomitant Cytochrome P450 3A4 (CYP3A4) Inhibitors	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). A total of 38 drugs including tofisopam, bromocriptin mesilate, and fluvoxamine maleate were defined as CYP3A4 inhibitors.	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Who Were Under Long-Term Treatment	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). The long-term treatment was defined as the treatment continued more than 24 weeks.	MAX 2 Years
Numbers of Participants With Treatment-Related Adverse Events Corresponded to Items for Priority Investigation	The following adverse events were defined as items for priority investigation : (1) lung disorder including interstitial pneumonia, (2) bone marrow depression including platelets decreased, white blood cell decreased, and anaemia, (3) haemorrhage including those due to tumor degeneration or shrinkage, (4) cardiac function disturbance including QT interval prolonged and left ventricular ejection fraction decreased, (5) dysfunction adrenal, (6) pancreatic dysfunction including lipase increased, (7) thyroid function decreased, (8) cutaneous symptoms (hand and foot syndrome), (9) serious infections, (10) rhabdomyolysis, myopathy, and (11) reversible posterior leukoencephalopathy syndrome (RPLS). Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.).	MAX 2 Years

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment-Related Serious Adverse Events	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. A treatmen-trelated serious adverse event was a treatment-related adverse event resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; lifethreatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.).	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Unexpected From Japanese Package Insert	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). Expectedness of the adverse event was determined according to the Japanese package insert. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.).	MAX 2 Years
Number of Participants With Treatment-Related Adverse Events Grade 3 or Higher in Common Toxicity Criteria for Adverse Events (CTCAE)	A treatment-related adverse event was any untoward medical occurrence attributed to sunitinib malate in a participant who received sunitinib malate. Relatedness to sunitinib malate was assessed by the investigator and sponsor (Pfizer Japan Inc.). The severity for each adverse event was assessed according to CTCAE as follows: grade 3, severe or medically significant but not immediately life-threatening, hospitalization or prolongation of hospitalization indicated, or disabling; grade 4, life-threatening consequences or urgent intervention indicated; grade 5, death related to adverse event.
