Sunitinib Malate With or Without Gemcitabine Hydrochloride in Treating Patients With Advanced Kidney Cancer That Cannot Be Removed By Surgery

Phase 2

Completed

Conditions: Kidney Cancer

Interventions: Drug: Gemcitabine
Drug: Sunitinib

Registration Number: NCT01164228

Lead Sponsor: ECOG-ACRIN Cancer Research Group

Brief Summary: RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth or tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving sunitinib malate and gemcitabine hydrochloride together is more effective than sunitinib malate alone in treating patients with kidney cancer.

PURPOSE: This randomized phase II clinical trial is studying giving sunitinib malate together with or without gemcitabine hydrochloride to see how well they work in treating patients with advanced kidney cancer that cannot be removed by surgery.

Detailed Description: OBJECTIVES:

Primary

* To evaluate the response rate to sunitinib malate with vs without gemcitabine hydrochloride in patients with advanced renal cell carcinoma with sarcomatoid features.

Secondary

* To evaluate progression-free survival of these patients.

* To evaluate overall survival of these patients.

* To describe the toxic effects of both sunitinib malate alone and in combination with gemcitabine hydrochloride in these patients.

OUTLINE: This is a multicenter study. Patients are stratified according to risk (good risk \[clear cell and \< 20% sarcomatoid and performance status (PS) 0\] vs intermediate risk \[20-50% sarcomatoid and PS 0\] vs poor risk \[non-clear cell or \> 50% sarcomatoid or PS 1 or non-clear cell\]). Patients are randomized to 1 of 2 treatment arms.

* Arm A: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, 22, and 29 and oral sunitinib malate once daily on days 1-14 and 22-35.

* Arm B: Patients receive oral sunitinib malate once daily on days 1-14 and 22-35.

In both arms, courses repeat every 42 days for up to 1 year in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year.

ACTUAL ACCRUAL: A total of 87 patients (47 in arm A and 40 in arm B) were accrued to this study.

Arm && Interventions

Group	Intervention	Description
Arm A (Sunitinib + Gemcitabine)	Gemcitabine	Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, 22, and 29 and oral sunitinib malate once daily on days 1-14 and 22-35. Each cycle was 42 days (6 weeks) and was to be repeated for a total of one year.
Arm B (Sunitinib)	Sunitinib	Patients receive oral sunitinib malate once daily on days 1-14 and 22-35. Each cycle was 42 days (6 weeks) and was to be repeated for a total of one year.
Arm A (Sunitinib + Gemcitabine)	Sunitinib	Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, 22, and 29 and oral sunitinib malate once daily on days 1-14 and 22-35. Each cycle was 42 days (6 weeks) and was to be repeated for a total of one year.

Primary Outcome Measures

Name	Time	Method
Proportion of Patients With Response	Assessed every 3 months for 2 years and every 6 months for year 3.	Response is defined as either complete response (CR, disappearance of all lesions) or partial response (PR, at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters, or persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits).

Secondary Outcome Measures

Name	Time	Method
Progression-free Survival	Assessed every 3 months for 2 years and every 6 months for year 3.	Progression-free survival is defined as the time from randomization to progression or death, whichever occurs first. Progression is defined as follows: * At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. * Appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.
Overall Survival	Assessed every 3 months for 2 years and every 6 months for year 3.	Overall survival is defined as the time from randomization to death or date last known alive.
