MS-20 on Gut Microbiota and Risk/Severity of Cachexia in Pancreatic Cancer Patients

This is a double-blind, placebo-controlled, investigator-initiated randomized trial to evaluate the effects of MS-20 on gut microbiota and risk/severity of cachexia in patients receiving chemotherapy for pancreatic cancer. Approximately 40 subjects who meet the criteria will be enrolled into the study. The total of study comprises of a 28 days screening period, a 12-week treatment period and a 8-week follow-up period. Potential candidates should provide signed informed consent forms before starting any screening activities. MS-20 or placebo will be orally administered twice per day in treatment period. All medications (especially antibiotics) should be recorded and documented during the study period. The investigator may withdraw a subject from the study if any of the following conditions occurs: 1. Subjects who experiences a serious adverse event (SAE) or intolerable adverse event (AE), or laboratory safety assessments reveal clinically significant hematological or biochemical changes from baseline values. 2. The subject would like to withdraw consent and discontinue from the study at any time, for any reason, without any influence on further treatment. (Patients who withdraw or terminate early from study should proceed to EOT visit for safety evaluation.)
