The research drug, KLT, is purified from a traditional Chinese medicine called coix seed. It is approved in China for use in combination with chemotherapy to treat patients with advanced lung cancer and liver cancer. It is also approved in China for use by itself to treat the symptoms of cancer in patients with advanced cancer of any kind. In the US, KLT is purely experimental and is not approved for any use. While a small number of cancer patients in the US have received KLT alone in a Phase I study, this is the first US protocol to evaluate whether or not KLT is useful in pancreatic cancer.
