ClinConnect Summary

This clinical trial is looking at a new treatment approach for patients with certain types of kidney cancer and kidney problems. Specifically, it aims to see if combining two medications, DV and toripalimab, can help preserve kidney function while treating tumors in the upper urinary tract. The study will involve about 20 participants who will receive these medications through an IV every two weeks for a total of six cycles. After this treatment, participants will have laser surgery to remove tumors, followed by more cycles of DV and toripalimab to help maintain the treatment's effects.

To participate in this trial, individuals must be at least 18 years old and have a confirmed diagnosis of kidney cancer or related kidney issues. They should be considered high-risk for surgery and must have normal organ function. Participants can expect regular check-ups, including tests and imaging, to monitor their health and the effectiveness of the treatment. This research is currently recruiting, and those interested will need to provide informed consent, meaning they understand the study and agree to take part.
