Trial of Encapsulated Rapamycin (eRapa) for Bladder Cancer Prevention (NCT04375813)

Phase II Trial of Encapsulated Rapamycin (eRapa) for Bladder Cancer Prevention

🔵 Active, Not Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: Robert Svatek

🩺 Plain-English Summary (8th-Grade Level)

eRapa (encapsulated rapamycin) will be investigated for secondary prevention in patients with diagnosed non-muscle invasive bladder cancer (NMIBC) through a phase II double-blind randomized controlled trial of long-term (one year) prevention with eRapa versus placebo. The primary hypothesis is that eRapa decreases the risk of cancer relapse for patients with NMIBC. Secondary hypotheses are that eRapa can improve certain immune parameters and improve cognition and physical function without adversely affecting patient-reported outcomes and quality of life.
