Bevacizumab, Autologous Tumor/DC Vaccine, IL-2 and IFNα-2b in Metastatic Renal Cell Carcinoma (RCC) Patients

Stopped early · Phase 2

Conditions studied: Metastatic Renal Cell Carcinoma

In brief

Immune therapies, such as a IL-2, for metastatic renal cell carcinoma (mRCC) are designed to mobilize immune effector cells that recognize and destroy cancer. The investigators have recently observed a 50% objective response rate (16% CR) in mRCC patients treated with autologous tumor lysate -dendritic cell (DC)-vaccine, IL-2 and interferon alfa (IFN). New agents inhibiting vascular endothelial growth factor (VEGF) pathways have demonstrated significant benefit in mRCC patients as well, but rarely induce CRs. High blood VEGF is associated with poor response to IL-2 and can cause tumor specific immune dysregulation. To test whether complementary mechanisms of immune activation and disruption of regulatory pathways enhance outcome the investigators plan to treat 24 mRCC patients in a phase II trial using bevacizumab, DC vaccine, IL-2, and IFN. Observations from this project will be used in the development of novel cancer therapies which, if successful, will decrease the burden of cancer on the public. The investigators propose to determine 1) the objective clinical response rate to treatment and progression free survival, 2) the clinical and autoimmune related toxicity profile of therapy, and 3) the treatment related tumor-specific immune response and the relationship of tumor-specific immune response and objective clinical response.

You may qualify if…

Histologically confirmed metastatic renal cell carcinoma with measurable disease.
Adequate tumor tissue properly stored and available to produce lysate for a minimum of three vaccine preparations.
Patients must be at least 4 weeks from their last therapy (tyrosine kinase inhibitors, immunotherapy, radiation, surgery or chemotherapy (6 weeks for nitrosureas) and recovered from all ill effects.
Have measurable disease.
Patients must be at least 4 weeks from major surgery, 1 week from minor surgery, and recovered from all ill effects.

You may not qualify if…

Patients who have previously received bevacizumab or IL-2 are not eligible.

In patients with a prior history of invasive malignancy, less than five years in complete remission.
Positive serology for HIV, hepatitis B or hepatitis C which should be confirmed with antigenemia.
Significant co-morbid illness such as uncontrolled diabetes or active infection that would preclude treatment on this regimen.
