Condition(s) targeted: Renal Cell Carcinoma

Intervention: Sunitinib (Drug); Bevacizumab (Drug)

Phase: Phase 2

Status: Withdrawn

Summary

The purpose of this research study is to further define an effective strategy for people with renal cell carcinoma and to learn the safety and effectiveness of two different types of sunitinib-refractory treatments: Bevacizumab alone or a combination of sunitinib and bevacizumab. Sunitinib is an FDA approved drug and is currently one of the standard treatments for advanced renal cell carcinoma. However, some people who receive this treatment do not respond to treatment or they stop responding to treatment. Bevacizumab is an FDA approved drug used for the treatment of several cancers however, is not yet approved for use in renal cell carcinoma.

Clinical Details

Official title: Phase II, Randomized Trial of Bevacizumab With or Without Sunitinib in Sunitinib-Refractory Patients With Metastatic Renal Cell Carcinoma

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: To determine the time to tumor progression (TTP) in this patient population treated with bevacizumab or combination of sunitinib and bevacizumab.

Secondary outcome:

To determine the overall response rate in this patient population.

To evaluate the safety and tolerability of these treatments in mRCC patients with disease progression on standard dose sunitinib.

To collect serum research samples for analysis of predictive biomarkers of response.

Detailed description:

- Participants will receive one of two treatment possibilities. Since no one knows which

of the study options is best, participants will be "randomized" to one fo the three treatment groups.

- Group 1 will stop their current treatment with sunitinib and receive a dose of

bevacizumab once every 2 weeks. Group 2 will receive the standard treatment of sunitinib with the addition of bevacizumab.

- All study participants will undergo the same study procedures. These study procedures

will include the following at intervals specified in the protocol: medical history review; vital signs; physical exam; urine analysis; EKG and CT scan.
