Institution: 21st Century Oncology (complete)
Title: Pragmatic test of amino-acid mixture/enterade® for Gastrointestinal Toxicity in Cancer Therapy.
Sample Size: 155 subjects.
Primary Objective: Determine if consumption of enterade® reduced diarrhea and other symptoms of gastrointestinal toxicity in cancer patients receiving radiotherapy and/or chemotherapy.
Primary Endpoint: Composite response for Nausea, Diarrhea, vomiting, oral mucositis, bloating and cramping or any type of radiotherapy and or chemotherapy secondary adverse effect (weight maintenance, dehydration, malaise). Patient reported improvement in: diarrhea, dehydration, nausea, fatigue, oral mucositis.
Secondary Endpoints: Safety, tolerability, compliance.

Space Institute funded study shows that enterade® Advance Oncology (amino acid-based oral rehydration solution) increased villus height and improved electrolyte and nutrient absorption in irradiated mice.

Entrinsic Health Solutions, Inc., an innovative health sciences company announced the publication of results from research at the University of Florida using enterade® Advanced Oncology (AO) formulation titled, “An amino acid-based oral rehydration solution (AA-ORS) enhanced intestinal epithelial proliferation in mice exposed to radiation.” The full article can be found in the 23 November, 2016 issue of Nature at  The article is also available in the News & Media section of the Entrinsic Health Solutions website at
