Study Summary

This trial is testing a new combination therapy for people with urothelial carcinoma who are ineligible or refuse chemotherapy.

Who is the study for?
This trial is for adults with advanced urothelial carcinoma who haven't been treated yet and can't have or don't want chemotherapy. They should be in good health overall, able to consent, and not have certain other medical conditions like active brain metastases, immune deficiencies, uncontrolled high blood pressure, or recent live vaccines.Check my eligibility
What is being tested?
The study tests a combination of Pembrolizumab (an immunotherapy drug) and sEphB4-HSA (a protein that may stop tumor growth), focusing on patients with untreated advanced urothelial carcinoma ineligible for or refusing chemotherapy.See study design
What are the potential side effects?
Potential side effects include reactions related to the immune system attacking normal cells leading to inflammation in various organs, infusion-related reactions from the treatment administration process, fatigue, possible changes in liver function tests and risk of infections.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Estimate of the overall response rate (ORR) of the combination of Pembrolizumab + sEphB4-HSA in the patients with previously untreated advanced (metastatic or recurrent) urothelial carcinoma who are chemotherapy ineligible or who refuse chemotherapy
Secondary outcome measures
To determine the tolerbility of the combination of Pembrolizumab + sEphB4-HSA in patients with previously untreated advanced urothelial carcinoma is more effective than the single agent pembrolizumab.
To estimate the overall survival (OS) in these patients
To estimate the progression free survival (PFS) in these patients
