Can high dose, intravenous Vitamin C prolong life for patients with metastatic prostate cancer?
Prostate cancer is the most common cancer (excluding skin cancer) in men in Denmark and the Unites States. When metastatic disease is present cure is no longer possible. The main treatment at this stage is castration, either surgical or medical, ending the patients testosterone production and causing a temporary regression in disease activity.
Eventually, the cancer will progress, usually within 2 years from the castration, with a more aggressive course and a survival of 2-3 years.
The current treatment option for the patients, who have undergone castration and have disease progression, is chemotherapy with only limited gains in quality of life and survival.
This clinical study is a phase 2 study to evaluate the effects of high dose intravenous vitamin c in subjects with early castration resistant prostate cancer.

Vitamin C for palliative treatment:
Intravenous vitamin C has been used since the 1970's for terminally ill cancer patients claiming big increases in survival time. The efficacy of the drug is questioned and no randomized, controlled trial of Vitamin C's efficacy on cancer patients survival has been made.
Recent results from in vitro and xenograft studies in mice has shown some promise for vitamin c as a cytotoxic agent against cancer cells.
The following parameters are recorded for baseline:
These parameters are repeated after treatment, usually after 12 to 26 weeks after the first vitamin c infusion.
