Optimer Pharmaceuticals, Inc. (Nasdaq:OPTR) today announced that the company has completed enrollment in the second of two planned phase 3 clinical trials evaluating the safety and efficacy of Prulifloxacin for the treatment of infectious diarrhea in travelers. The Company previously reported positive top-line data from the first Phase 3 trial which showed that Prulifloxacin met the primary endpoint of Time to Last Unformed Stool (TLUS), a measure of the time to resolution of diarrhea, compared to placebo with a p-value of <0.0001. If the results of this second study are also positive, the Company expects to use these studies as a basis for a New Drug Application filing in 2009.
Travelers’ diarrhea is infectious diarrhea caused by bacteria, viruses or parasites and is contracted by the ingestion of contaminated food or water. This infection is characterized by diarrhea along with other related symptoms including nausea, vomiting, abdominal pain or cramping, and fecal urgency.
“We are very excited to have completed enrollment in the second trial,” said Michael N. Chang, Ph.D., CEO and President of Optimer. “We look forward to completing the analysis of the data from this trial and we expect top-line results in the fourth quarter.”
This multi-center, double-blind, randomized and placebo-controlled clinical trial compares the safety and efficacy of Prulifloxacin versus placebo in adult travelers suffering from acute bacterial gastroenteritis. Clinical trial sites included locations in India, Guatemala, and Mexico. The primary endpoint is TLUS and secondary endpoints include clinical cure based on relief of symptoms and microbiological eradication rates.
