A clinical trial in human patients with ovarian cancer has shown some promising results. All patients in this study were undergoing chemotherapy, but some received high doses of intravenous vitamin C as well. After following these patients for five years, it was found that the patients who received vitamin C experienced fewer toxic effects from chemo!
That’s pretty good news. And this is an interesting example of animal research at work. Years ago, oral doses of vitamin C weren’t found to be effective. But by working with a combination of cell cultures and animals, researchers were able to determine that IV doses could be much more effective than oral doses, and they found that at high doses, vitamin C can kill cancer cells without harming normal cells. Often, drugs administered by different routes can work in different ways- when taken orally, vitamin C is often absorbed quickly and doesn’t stay in your system for long. So animals played a big role in understanding the proper route of administration, and now human patients will be seeing the benefits of that work!
Now that safety and toxicity studies have been performed, expect to see this therapy introduced into further clinical trials! Are you interested in clinical trials in your area? Go to www.clinicaltrials.gov!
