Study Summary

This trial will test a novel combination of drugs to treat urothelial cancer, as well as their side effects and efficacy.

Who is the study for?
Adults with transitional cell urothelial cancer, which includes cancers of the renal pelvis, ureter, bladder or urethra. They must have advanced or metastatic disease and can have had up to two prior treatments for it. Participants need a life expectancy of at least 12 weeks and should be able to follow the study's schedule. Exclusions include those with certain immune conditions, recent live vaccines, organ transplants, uncontrolled HIV infection, pregnancy or breastfeeding.Check my eligibility
What is being tested?
The trial is testing naptumomab estafenatox (NAP) combined with pembrolizumab after an initial treatment with obinutuzumab in patients with urothelial cancers. The hypothesis is that NAP will boost pembrolizumab's effectiveness against cancer. Treatment involves cycles where NAP is given daily for four days followed by pembrolizumab every three weeks for up to two years.See study design
What are the potential side effects?
Potential side effects may include reactions related to infusion such as fever or chills; immune-related issues like inflammation in various organs; fatigue; possible increased risk of infections due to immunosuppression; and other drug-specific adverse effects that will be monitored throughout the trial.

Group I: Naptumomab estafenatox in combination with pembrolizumab preceded by ObinutuzumabExperimental Treatment3 Interventions
The study will test two doses of NAP 5 µg/kg/day IV (Dose Level 1) and 10 µg/kg/day IV (Dose Level 2), in combination with a fixed dose of pembrolizumab (200mg IV every 3 weeks). NAP will be given on Days 1-4 of each 21 day cycle for 6 cycles. Pembrolizumab will be given on Day 2 of each 21-day treatment cycle for the first 6 cycles and then as monotherapy every 21 days for up to a total of 34 administrations. Two doses of Obinutuzumab 1,000 mg IV will be given before starting NAP and pembrolizumab on Days - 13 and -12. Pembro 200 mg i.v. Day 2 of each 21-day treatment cycle for the first 6 cycles
