The purpose of this study is to determine the effectiveness of sunitinib on participants with ovarian, fallopian tube or peritoneal cancer. Sunitinib is a newly discovered drug that may stop cancer cells from growing by blocking the blood supply to the tumor.
This study used a two-stage design to evaluate efficacy of sunitinib based on overall response (OR) defined as complete response (CR) or partial response (PR). The null and alternative OR rate were 5% and 20%. If one or more patients enrolled in the stage one cohort (n=17 patients) achieved PR or better than accrual would proceed to stage two (n=18 patients). There was 42% probability of stopping the trial at stage one if the true OR rate was 5%. With 35 patients, this design had 85% power to detect the 15% difference in OR rates assuming 2-sided type I error rate of 0.05.

Overall Response Rate
Best response on treatment was based on RECIST 1.0 criteria with overall response defined as achieving partial response (PR) or complete response (CR). Per RECIST 1.0 for target lesions, CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. To be assigned a status of CR or PR, changes in tumor measurements must be confirmed by repeat assessments performed no fewer than 4 weeks after the response criteria are first met. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.
Time frame: Clinical assessments were performed weekly for first 4 weeks and every 2 wks in subsequent cycles. Disease was evaluated radiologically at baseline, before each odd cycle and at end of trt.
16-Week Progression-Free Survival
16-week progression-free survival is the probability of patients remaining alive and progression-free at 16-weeks from study entry estimated using Kaplan-Meier methods. Patients alive and progression-free at last follow-up are censored. Progressive disease (PD) based on RECIST 1.0 is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or equivocal progression of non-target lesions.
Time frame: Clinical assessments were performed weekly for first 4 weeks and every 2 weeks in subsequent cycles. Disease was evaluated radiologically at baseline, before each odd cycle and at end of treatment.
Progression-Free Survival
Progression-free survival estimated using Kaplan-Meier methods is defined as the time from registration to the earlier of death or disease progression. Patients alive without disease progression are censored at the date of last disease evaluation. Progressive disease (PD) based on RECIST 1.0 is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Equivocal progression of non-target lesions also qualifies as PD.
