Clinical Trial Summary

This is a non-blinded phase 2 trial in Stage II-IIIa urothelial cancer randomizing pre-operative nivolumab with or without relatlimab to assess whether bladder preservation after dual immunotherapy would be a viable treatment option for patients responding to treatment

Clinical Trial Description

This is a phase 2 study in which ninety adult patients with cT2-4aN0 or cT1-4aN1urothelial bladder cancer will be included.

Included patients will be treated with two cycles of checkpoint inhibition with nivolumab or two cycles of nivolumab+relatlimab every 28 days.

Response of this induction therapy will be evaluated by cystoscopy, mpMRI and a CT scan.

The primary endpoint is efficacy, defined as pathological complete response (pCR) defined as pT0N0 or pTisN0 at cystectomy.

Secondary end-points consist of feasibility analysis, defined as percentage of patients completing cystectomy within 12 weeks of start of treatment. Other key secondary end points are drug safety and overall and event-free survival. Events consist of death by any cause; disease recurrence inside or outside the urinary tract and switching to other treatments.

The first evaluation after completion of both treatment cycles will be after six months. Further follow-up visits will take place at 12 and 24 months after completion of the treatment. During these visits, focused physical examination, cystoscopy and a CT chest-abdomen will be performed, combined with registration of treatment-related adverse events and a questionnaire for evaluating QoL, bladder function and long-term effects of immunotherapy on QoL. ;
