Brief Title: Efficacy and Safety of Intravesical TARA-002 Compared With Investigator’s Choice of Intravesical Chemotherapy in Participants With BCG-naïve High-grade Non-muscle Invasive Bladder Cancer

A Phase 3, Randomized Study to Evaluate the Efficacy and Safety of Intravesical TARA-002 Compared With Investigator's Choice of Intravesical Chemotherapy in Participants With BCG-naïve High-Grade Non-Muscle Invasive Bladder Cancer

INTRODUCTION

  • Org Study ID: TARA-002-301
  • Secondary ID: N/A
  • NCT ID: NCT07480356
  • Sponsor: Protara Therapeutics

BRIEF SUMMARY

The goal of this clinical trial is to learn if TARA-002 can treat high-grade non-muscle invasive bladder cancer (NMIBC) in BCG-naïve adults 18 years of age or older.

The main questions it aims to answer are:

* Can the study drug help participants with this type of cancer?
* Is the study drug safe?
* What are the side effects of the study drug?

Researchers will compare TARA-002 to chemotherapy to see if TARA-002 works to treat NMIBC.
