Summary
Brief summary (as posted)
Study Hypothesis: EW02 is a polysaccharide-enriched crude extract from black soybean (BS). BS has been used extensively by the Chinese as food or traditional Chinese medicine for hundreds of years. It has been used as monotherapy to treat Diabetes, menorrhagia and leukorrhea. In combination with others, BS has been used to treat chemotherapy-induced leukopenia on more than 300 pts. The daily doses were 15g bid to 50g tid for 21 days. Side effects were generally mild, including epigastric discomfort, numbness, insomnia, and dry mouth. Recently BS was found to promote myelopoiesis and inhibit tumor growth through immunomodulation. In vitro assays showed BS-PS can stimulate production of cytokines and increase blood progenitors. In vivo studies also demonstrated that BS-PS can reduce neutropenia in mice received 5-FU by stimulating myeloid colony formation. We hypothesize that EW02 can reduce neutropenia in cancer patients who receive chemotherapy without side effects.
