Cadonilimab Plus Nab-Paclitaxel for Recurrent or Metastatic Muscle Invasive Bladder Cancer
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to evaluate the efficacy and safety of Cadonilimab(AK104) combined with Nab -Paclitaxel as first line therapy for recurrent or metastatic muscle invasive bladder. Eligible participants will receive AK104 (up to 24 months) plus Nab-Paclitaxel (for 6 cycles) until radiologic disease progression, unacceptable toxicity, or withdrawal from the study, whichever occurred first. The primary endpoint is objective response rate.

Detailed Description
Cadonilimab(AK104) is a first-in-class bispecific, humanized IgG1 antibody targeting PD-1 and CTLA-4, which has the potential to boost immune surveillance in tumors. The goal of this clinical phase II trial is to evaluate the efficacy and safety of AK104 combined with Nab-Paclitaxel as first line therapy for recurrent or metastatic muscle invasive bladder.
