Official title
Neoadjuvant Combination Pembrolizumab / Enfortumab Vedotin With Adjuvant Pembrolizumab Prior to and After Radical Nephroureterectomy for High-Risk Upper Tract Urothelial Carcinoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II clinical trial tests how well pembrolizumab plus enfortumab vedotin prior to and after radical nephroureterectomy works in treating patients with high-risk upper tract urothelial cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Enfortumab vedotin (EV) is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. It works by helping the immune system to slow or stop the growth of cancer cells. Enfortumab attaches to a protein called nectin-4 on cancer cells in a targeted way and delivers vedotin to kill them. It is a type of antibody-drug conjugate. Radical nephroureterectomy (RNU) is the surgical removal of a kidney and its ureter. Giving pembrolizumab plus enfortumab vedotin before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed and giving pembrolizumab after surgery may kill any remaining cancer cells.
