Vitamin c boost: could high doses help chemo fight tough blood cancers?
NCT ID NCT03418038
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding high-dose vitamin C (ascorbic acid) to standard chemotherapy can help kill cancer cells better in people with certain blood cancers that have returned or not responded to treatment. It includes adults with relapsed or refractory lymphoma, clonal cytopenia of undetermined significance, and chronic myelomonocytic leukemia. The goal is to see if the combination improves response rates and is safe.
