DV Combined With Toripalimab for Renal Preservation in Solitary Kidney or Renal Insufficiency or Bilateral Multiple UTUC

NCT ID: NCT06354231

Last Updated: 2024-04-11

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-07-20
• Study Completion Date: 2026-12-30

Brief Summary

Approximately 20 participants will be enrolled in the study to evaluate the efficacy and safety of the combination of DV (DV, 2.0 mg/kg, intravenously administered every 2 weeks) and toripalimab (toripalimab, 3.0mg/kg, intravenously administered every 2 weeks). Subjects will receive 6 cycles of DV and toripalimab, followed by laser surgery to remove ureteral or renal pelvis tumors, followed by 12 cycles of DV and 1 year of toripalimab consolidation therapy. Efficacy and safety were evaluated by cystoscopy, ureteroscopy, laboratory tests, and imaging examinations after treatment.
