Effektivitet og sikkerhed af intravesikal TARA-002 sammenlignet med undersøgelseslederens valg af intravesikal kemoterapi hos deltagere med BCG-naiv højgradig ikke-muskelinvasiv blærecancer (ADVANCED-3)

5. oktober 2026 opdateret af: Protara Therapeutics

En fase 3, randomiseret undersøgelse til evaluering af effektiviteten og sikkerheden af intravesikal TARA-002 sammenlignet med forsøgslederens valg af intravesikal kemoterapi hos deltagere med BCG-naiv højgradig ikke-muskelinvasiv blærekræft

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.
