Oligo-Fucoidan Decrease Lung Radiation Damage

A Phase II Trial of Oligo-Fucoidan in Radiation Induced Ling Injury

Fucoidan is FDA approved and in common use for treatment of angina. These studies will advance that work to human use. Successful mitigation of lung radiation damage and heart toxicity will improve the quality of life in veterans and non-veterans who are treated for lung cancer by radiation, and may also improve cure rates of radiation therapy for lung cancer.

This project will test the effect of Fucoidan to mitigate the lung damage that can occur as a side effect of radiation therapy for lung cancer. Thousands of veterans develop lung cancer every year, and are treated by radiation therapy. Studies of lung radiation injury in laboratory animals show that with Fucoidan, investigators can significantly reduce the severity of lung fibrosis and heart toxicity.1,2 Fucoidan is FDA approved and in common use for treatment of angina.
