Early Termination and Withdrawal of Phase 3 Clinical Trial for Overactive Bladder Drug UIP620


  • Sinsin Pharmaceutical decided to early terminate and voluntarily withdraw the Phase 3 clinical trial for overactive bladder treatment UIP620
  • Reason for withdrawal: the trial required more subjects (target 686) and operational resources than initially expected; the company plans to pivot to a better well-aging project and pursue joint development
  • The trial was approved in July 2024 with a 24-month timeline, but early termination was reported to MFDS on May 22, 2026
