Pembrolizumab + Entinostat for Bladder Cancer

Phase 2
Waitlist Available
Led By Tracy L Rose, MD
Research Sponsored by UNC Lineberger Comprehensive Cancer Center
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Histological confirmation of urothelial carcinoma of the bladder; those with mixed histology, including a component of urothelial carcinoma, are eligible. Pure small cell carcinoma, pure adenocarcinoma, and pure squamous cell carcinoma are excluded
Subject has clinical stage T2-T4a N0/X M0 urothelial carcinoma. Clinical T stage is based on the pre-study standard of care transurethral resection of the bladder tumor (TURBT) sample and imaging studies (abdominal/pelvic CT or MRI scan and CT scan of the chest performed within 4 weeks prior to treatment initiation)
Must not have
Subject has a known history of active tuberculosis
Subject has known history of Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] has been detected)
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to 3 years

Summary

This trial is testing a new cancer treatment combining immunotherapy with a class I HDAC inhibitor. The goal is to see if the treatment changes immunogenomic markers in patients with muscle-invasive bladder cancer who are ineligible for cisplatin-based neoadjuvant chemotherapy.

Who is the study for?
Adults with muscle-invasive bladder cancer who can't or won't take cisplatin-based chemo and are set for surgery or trimodality therapy. They must be able to provide tissue samples, have a life expectancy over 3 months, and show adequate organ function. Women of childbearing age need to use contraception.
What is being tested?
The study is testing the effects of Pembrolizumab alone and combined with Entinostat on immune markers in bladder cancer patients ineligible for certain chemotherapy before their scheduled surgeries.
What are the potential side effects?
Pembrolizumab may cause immune-related reactions, fatigue, skin issues, digestive problems, liver inflammation, hormone gland changes. Entinostat could lead to blood cell count changes, fatigue, nausea, diarrhea, changes in sense of taste.
