Impact of Microbiome Modulation With CBM588 in Combination With Pembrolizumab for Adjuvant Therapy of High-Risk, Resected Renal Cell Carcinoma (RCC)
City of Hope Medical Center
Summary
This phase II trial compares the effect of adding a Live Biotherapeutic Product called CBM588 to pembrolizumab versus pembrolizumab alone in preventing return of disease (recurrence) after surgery for patients with renal cell cancer. Pembrolizumab is an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies such as pembrolizumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pembrolizumab is approved for the treatment of renal cell cancer after surgery. Research has shown that changes to the composition of the healthy bacteria in the body (the microbiome), may improve a patient's response to treatment with immunotherapy. CBM588, a Live Biotherapeutic Product (LBP) containing a bacteria called Clostridium butyricum, has been shown to improve outcomes in patients treated with immunotherapy for other types of cancer. Adding CBM588 to treatment with pembrolizumab after surgery may cause changes in the microbiome that improve patient response to treatment and reduce disease recurrence, compared to pembrolizumab alone.
Description
PRIMARY OBJECTIVE: I. To determine if the Clostridium butyricum CBM588 strain (CBM588) increases interleukin (IL)-12 production in patients with high-risk, resected renal cell carcinoma (RCC) receiving pembrolizumab. SECONDARY OBJECTIVES: I. To determine if CBM588 improves recurrence-free survival (RFS) in patients with high-risk, resected renal cell carcinoma (RCC) receiving pembrolizumab. II. To determine if CBM588 improves overall survival (OS) in patients with high-risk, resected renal cell carcinoma (RCC) receiving pembrolizumab. III. To characterize global changes in stool microbiom…
