Официальное название

A Phase 2 Multi-Cohort, Open-Label, Multi-Center Clinical Study Evaluating the Efficacy and Safety of Disitamab Vedotin (RC48-ADC) Alone or in Combination With Pembrolizumab in Subjects With Locally-Advanced Unresectable or Metastatic Urothelial Carcinoma That Expresses HER2

Обзор

This study is being done to see if a drug called disitamab vedotin, alone or with pembrolizumab, works to treat HER2 expressing urothelial cancer. It will also test how safe the drug is for participants. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). It will also study what side effects happen when participants get the drug. A side effect is anything a drug does to your body besides treating the disease.

Вмешательства

Препарат disitamab vedotin
Given into the vein (IV; intravenous) every 2 weeks.
Препарат pembrolizumab
Given by IV on Day 1 of each 6-week cycle.
