Summary

This trial is testing whether adding intravenous ascorbate (vitamin C) to gemcitabine/carboplatin chemotherapy will increase therapeutic efficacy in patients with bladder cancer who are ineligible for cisplatin-based chemotherapy.

Who is the study for?
This trial is for adults with muscle invasive bladder cancer who can't have cisplatin-based chemotherapy. They must be in fair to good health, not pregnant or breastfeeding, and willing to use birth control. Smokers and those with certain medical conditions or treatments are excluded.
What is being tested?
The study tests if adding high-dose vitamin C (IVC) to the chemo drugs carboplatin and gemcitabine helps treat bladder cancer better than chemo alone. It's for patients who can't tolerate the usual cisplatin drug due to other health issues.
What are the potential side effects?
High-dose IV vitamin C may cause side effects like headache, fatigue, nausea, and possible complications at the injection site. When combined with chemotherapy drugs, there might also be increased risk of blood disorders and organ stress.
