Summary

This trial aims to enroll patients with bladder cancer who cannot receive cisplatin or choose not to have cisplatin-based treatment. The study will look at how adding IVC to gemcitabine

Who is the study for?
This trial is for patients with muscle invasive bladder cancer who can't have cisplatin or choose not to. It's a phase II study, meaning it's checking the effectiveness and safety of adding high-dose vitamin C (IVC) to standard chemo drugs gemcitabine and carboplatin.
What is being tested?
The trial tests whether intravenous ascorbic acid (high-dose vitamin C) combined with gemcitabine/carboplatin chemotherapy can be an effective treatment that also improves quality of life for those with muscle invasive bladder cancer who aren't using cisplatin.
What are the potential side effects?
Potential side effects may include reactions at the injection site, fatigue from chemotherapy, kidney stones due to high levels of vitamin C, nausea, low blood counts increasing infection risk, and possible interference with glucose tests.
