A Study of HS-10566 in Patients With High-risk Non-muscle-invasive Bladder Cancer Who Are Ineligible for or Refuse Radical Cystectomy
brief summary
This is a multicenter, open-label, Phase I/II clinical study evaluating the safety, efficacy, tolerability, and pharmacokinetic/pharmacodynamic (PK/PD) profiles of HS-10566 in patients with high-risk non-muscle-invasive bladder cancer who are ineligible for or refuse radical cystectomy. The study comprises two distinct phases: a dose exploration phase and a proof-of-concept phase.
detailed description
The study will commence with a dose exploration phase employing a safety lead-in approach. Treatment cycles are 28 days in duration, with investigational product administration continuing for 2 years or until disease progression or fulfillment of other treatment discontinuation criteria. Each dose level will enroll 6 participants for dose-limiting toxicity (DLT) assessment to evaluate the tolerability, safety, and PK/PD profiles of HS-10566. The Safety Review Committee (SRC) will determine subsequent dose levels for exploration via joint review.
Following identification of safe dose levels in the exploration phase, one dose cohort will advance to the proof-of-concept phase, with each cohort enrolling up to 50 participants to further assess therapeutic efficacy and safety.
