A Phase III Study Comparing Pembrolizumab Combined with Sacituzumab Govitecan-hziy Versus Standard Chemotherapy for Advanced or Metastatic Urothelial Cancer

What this Trial Is About

Researchers are evaluating the effectiveness of pembrolizumab combined with sacituzumab govitecan-hziy compared to standard chemotherapy treatments in patients with advanced urothelial cancer that has spread locally or to other parts of the body. This phase III trial focuses on patients whose cancer has not responded to prior anti-PDL1 therapy. The study aims to compare overall survival, progression-free survival, response rates, duration of response, treatment side effects, and quality of life between the new combination therapy and usual chemotherapy care. Participants are randomly assigned to one of two treatment groups. One group receives standard chemotherapy options such as carboplatin or cisplatin with gemcitabine, or alternatively docetaxel or paclitaxel, given intravenously in 21-day cycles for up to six cycles or until disease progression or unacceptable side effects. The other group receives pembrolizumab intravenously on day 1 and sacituzumab govitecan-hziy intravenously on days 1 and 8 every 21 days for up to 35 cycles or two years, unless disease progresses or side effects become unacceptable. Both groups undergo blood tests and imaging scans like CT or MRI throughout the study. During the trial, participants will have regular assessments including blood sample collection and imaging to monitor their cancer status and treatment effects. Researchers will also evaluate patient-reported quality of life and fatigue at multiple time points up to 12 months. After completing treatment, participants are followed up 30 days later and then annually for five years to track survival and health outcomes. This comprehensive approach helps researchers understand both the clinical outcomes and the impact on patients well-being over time.
