Trial Outcomes & Findings for Pembrolizumab and BCG Solution in Treating Patients With Recurrent Non-Muscle-Invasive Bladder Cancer (NCT NCT02808143)

NCT ID: NCT02808143

Last Updated: 2024-06-26

Results Overview

Determine the MTD of the study drug (MK-3475) when administered intravesically in combination with BCG in patients with high risk or BCG-refractory non-muscle-invasive bladder cancer (up to the individual maximum tolerated dose of each drug alone). The MTD will be defined as the highest dose that causes dose limiting toxicities (DLTs) in \<2 of 6 patients graded by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.
