CCI-779 and Bevacizumab in Treating Patients With Metastatic or Unresectable Kidney Cancer

A Phase I/II Trial of CCI-779 and Bevacizumab in Stage IV Renal Cell Carcinoma

This phase I/II trial is studying the side effects and best dose of CCI-779 and bevacizumab and to see how well they work in treating patients with metastatic or unresectable kidney cancer. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of kidney cancer by blocking blood flow to the tumor. Giving CCI-779 together with bevacizumab may kill more tumor cells.

Study Overview

• Status: Completed
• Conditions: Clear Cell Renal Cell Carcinoma; Stage IV Renal Cell Cancer; Recurrent Renal Cell Cancer
• Intervention / Treatment: Drug: CCI-779; Drug: Bevacizumab

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the maximally tolerated dose (MTD) and recommended dosing for the combination of CCI-779 and Bevacizumab in patients with metastatic renal cell cancer. (Phase I) II. To determine the proportion of patients with metastatic renal cell cancer who are progression free at 6 months. (Phase II)

SECONDARY OBJECTIVES:

I. To determine the toxicity of the combination of CCI 779 and Bevacizumab in patients with metastatic renal cell cancer. (Phase II) II. To determine the clinical response rate of CCI 779 and Bevacizumab in patients with metastatic renal cell cancer. (Phase II) III. To determine the time to progression (TTP), disease free survival, and overall survival of CCI 779 and Bevacizumab in patients with metastatic renal cell cancer. (Phase II)

TERTIARY OBJECTIVES:

I. To identify predictive molecular markers of response, both at the tumor level and in the plasma/serum level, in an exploratory manner.

II. To correlate blood markers of angiogenesis with clinical activity of the combination of CCI-779 and Bevacizumab.

OUTLINE: This is a multicenter, phase I dose-escalation study followed by a phase II study. Patients are stratified according to study phase (I vs II).

Phase I: Patients receive CCI-779 IV on days 1, 8, 15, and 22 and bevacizumab IV on days 1 and 15.

Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of CCI-779 and bevacizumab until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Phase II: Patients receive CCI-779 and bevacizumab as in phase I at the MTD determined in phase I. After completion of study treatment, patients are followed every 3 months until disease progression and then every 6 months for up to 3 years after study entry.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dose-limiting Toxicity (DLT) (Phase I)	For this protocol, dose limiting toxicity (DLT) will be defined as an adverse event attributed (definitely, probably, or possibly) to the study treatment in the first four weeks of combination therapy, and meeting the following criteria: Grade 4 Absolute neutrophil count (ANC) for 5+ days.; Grade 4 anemia or thrombocytopenia of any duration.; Serum Creatinine 2 times baseline or 2x upper limit of normal if baseline levels not normal.; Any other non-hematologic grade 3 or higher as per NCI Common Terminology Criteria for Adverse Events (CTCAE) v. 3.0, except fatigue and grade 3 Hypertension that is will be controlled with oral medication.; Grade 3 triglycerides will be a DLT for patients who have Grade 3 in spite of appropriate lipid lowering drug therapy. The maximum tolerated dose level (MTD) will be defined as the highest safely tolerated dose where 1 or 0 out of 6 patients experience DLT with the next higher dose.	Patients observed a minimum of 4 weeks (one full course). The maximum number of cycles observed was 16 cycles.
Proportion of Progression-free Patients at 6 Months (Phase II)	Determination of progression will be made according to Response Evaluation Criteria in Solid Tumors (RECIST). A progression (PD) is defined as having at least a 20% increase in the sum of the longest dimension of target lesions taking as reference the smallest sum of the largest dimension recorded at baseline.The proportion of progression-free patients will be estimated by the number of successes divided by the total number of evaluable patients. Ninety-five percent confidence intervals for the success proportion will be calculated. All patients meeting the eligibility criteria who have signed a consent form and begun treatment will be considered evaluable. Those who die will be considered to have had disease progression unless documented evidence clearly indicates no progression has occurred.	6 months after study entry

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Best Response Rate of CCI-779 and Bevacizumab in Patients With Metastatic Renal Cell (Phase II)	The number of participants with clinical tumor response to treatment will be evaluated using the Response Evaluation Criteria In Solid Tumors (RECIST). Complete Response (CR): Disappearance of all target lesions Partial Response (PR): At least a 30% decrease in the sum of the largest dimension (LD) of target lesions taking as reference the baseline sum LD.	Up to 3 years from study registration
Time to Progression (Phase II)	The time to progression is defined as the time from registration to the time of progression. Those who die will be considered to have had disease progression unless documented evidence clearly indicates no progression has occurred. The distribution of time to progression will be estimated using the method of Kaplan-Meier.	Up to 3 years from study registration
Overall Survival (Phase I and II)	The overall survival or survival time is defined as the time from registration to death due to any cause. The distribution of overall survival will be estimated using the method of Kaplan-Meier.	Up to 3 years from study registration
