Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| SUNITINIB MALATE<br>Patients taking Sutent. | Drug: SUNITINIB MALATE<br>* SUTENT capsule 12.5 mg, depending on the Investigator prescription. Frequency and duration are according to Package Insert as follows. The usual adult dosage for oral sunitinib is 50 mg once daily, 4 weeks on followed by 2 weeks off (Schedule 4/2). This comprises 1 treatment cycle, which may be repeated. The dosage may be decreased according to the patient's clinical condition.<br>* Other names: SUTENT;|

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 |
