Safety Study of Specific Tumor Target Drug Plus Immune System Therapy in Patients With Kidney Cancer

Phase 2

Terminated

• Conditions: Carcinoma, Renal Cell
• Interventions: Drug: Bevacizumab; Drug: Interleukin-2

• Registration Number: NCT00440973
• Lead Sponsor: The Methodist Hospital Research Institute

Brief Summary

The purpose of this study is to determine if the combination of therapy to strengthen the immune system (Interleukin - 2) plus a specific tumor target therapy (Bevacizumab) can prolong the time between the start of treatment and disease progression, decrease tumor size, as well as determine if the combination therapy is safer and less toxic than the standard treatment for renal cell carcinoma.

Detailed Description

The standard first-line treatment for patients with metastatic RCC is IL-2 at higher doses, but associated with higher frequency of toxicities. IL-2 given at lower doses have demonstrated similar results than higher doses but it requires further study. RCC is highly vascular and expresses high levels of VEGF. Bevacizumab is a monoclonal antibody directed against the Vascular Endothelial Growth Factor (VEGF) responsible for angiogenesis.

The study is designed to evaluate a response defined as time to progression, safety and toxicity in patients with metastatic renal cell carcinoma. Tissue correlation to evaluate the impact of vascular VEGF on clinical outcome will be retrospectively performed

Inclusion Criteria

• Pathological proof of clear cell carcinoma (or mixed tumors ≥ 75% clear cell component)
• Evidence of measurable metastatic disease, no progression diseases or the patient's condition will not need radiotherapy in the next 4 weeks.
• Previous definitive radiotherapy to 1 metastatic site is acceptable
• At least 4 weeks have elapsed since radiation therapy
• Patients must be free of serious co-morbidity and have a life expectancy of ≥24 weeks
• Patients should have adequate physiologic reserves as evidence of adequate performance status, blood parameters, hepatic and kidney function, no evidence of active cardiac diseases and showing an acceptable function and adequate coagulation profile.

Exclusion Criteria

• Patients taking concurrent anticancer drugs
• Biphosphonates (Zometa) are not allowed, unless started 4 weeks prior to participation in the study
