Official title

A Pilot Feasibility Study of Sipuleucel-T vs. Sipuleucel-T and Low-protein Diet in Patients With Metastatic Castrate-resistant Prostate Cancer (CRPC)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a single-center, randomized, open-label study to assess the feasibility of a low-protein diet intervention in patients with metastatic castrate-resistant prostate cancer (CRPC) who are receiving treatment with sipuleucel-T. Subjects will be randomized (1:1 ratio) to either Arm 1 or Arm 2 (Fig. 1). Arm 1: Subjects randomized to Arm 1 will be treated with sipuleucel-T infusion on Day 1, every two weeks for a total of three infusions. Subjects on this arm will receive a control diet containing 20% protein. Arm 2: Subjects randomized to Arm 2 will be treated with sipuleucel-T infusion on Day 1, every two weeks for a total of three infusions. Subjects on this arm will receive a low-protein diet containing 10% protein. Patients with metastatic, asymptomatic or minimally symptomatic CRPC that has progressed despite androgen deprivation therapy will be eligible for the study. After informed consent eligible patients will be scheduled to receive sipuleucel-T (three infusions two weeks apart) with normal-protein diet vs. low-protein diet. Each cycle will be every 14 days. Diet intervention will commence 1 week prior to the first apheresis (Day -7) and will continue until 10 days after the last infusion of sipuleucel-T (Day +42) (Fig. 2).
