Study of NIVOLUMAB/IPILIMUMAB Maintenance in Unresectable Locally Advanced or Metastatic Urothelial Cancer

Immunotherapy has improved clinical outcomes in metastatic urothelial carcinoma (mUC). Second-line treatment after progression to platinum-containing chemotherapy with immune checkpoint inhibitors (ICIs) have antitumor activity in advanced / metastatic UC and provide favorable safety profiles when compared with chemotherapy The study aims to determine if Nivolumab plus Ipilimumab maintenance therapy is effective in delaying disease progression in patients with unresectable locally advanced or metastatic urothelial cancer that did not progress during or following completion of first-line chemotherapy. Vexillum plans to recruit patients that achieve clinical benefit from first-line chemotherapy and may be candidates for maintenance immunotherapy to consolidate this benefit.
