Prevention and treatment of secretory diarrhea by the lysophosphatidic acid analog Rx100

Diarrheal disease is a severe global health problem. It is estimated that secretory diarrhea causes 2.5 million deaths annually among children under the age of five in the developing world. A critical barrier in treating diarrheal disease is lack of easy-to-use effective treatments. While antibiotics may shorten the length and severity of diarrhea, oral rehydration remains the primary approach in managing secretory diarrhea. Existing treatments mostly depend on reconstituting medicines with water that is often contaminated which can be an unresolved problem in the developing world. Standard treatments for secretory diarrhea also include drugs that decrease intestinal motility. This approach is less than ideal because in cases where infection is the cause, this can increase the incidence of bacterial translocation and the potential for sepsis. Our goal is to develop a safe, effective, easy-to-use, and inexpensive treatment to reduce fluid loss in secretory diarrhea. We have developed Rx100, which is a meta...
