Study Endpoints

Primary Endpoints

Incidence of Enterotoxigenic Escherichia coli (ETEC) illness defined as a diarrheal episode associated with an LT, LT/ST, or ST-positive ETEC strain isolated from a sample of a stool
during the diarrheal episode or within 48 hours after the last stool in the diarrheal episode.
Safety of heat-labile enterotoxin of Escherichia coli (LT) delivered by transcutaneous immunization (TCI) vs placebo
From vaccination 1 to completion of Day 180 follow-up, about a seven month time period

Secondary Endpoints

Stool frequency per episode of ETEC illness in placebo recipients
Duration of stay in Mexico or Guatemala assessed up to four weeks
Immunogenicity of LT delivered by TCI
at least three weeks prior to arrival in country, arrival in Mexico or Guatemala, and 5 to 18 days after arrival
Incidence of irritable bowel syndrome following travel to areas of ETEC endemnicity.
Baseline through six months post return from Latin America. A period of about six months.

Frequently asked questions about Heat-Labile Enterotoxin of Escherichia coli

What is Heat-Labile Enterotoxin of Escherichia coli used for?

Heat-Labile Enterotoxin of Escherichia coli is being developed for the prevention of diarrhea. It is a monoclonal antibody candidate from Valneva SE, studied in a Phase 2 trial in healthy adult volunteers. The research targets diarrheal illness associated with enterotoxigenic Escherichia coli, a common cause of travelers' diarrhea.

Who is developing Heat-Labile Enterotoxin of Escherichia coli?

Heat-Labile Enterotoxin of Escherichia coli is being developed by Valneva SE, which trades under the ticker VALN. The company sponsored the Phase 2 ETEC Logistics Trial (TREK) evaluating the candidate in healthy volunteers across the United States, Guatemala, and Mexico.

What phase is Heat-Labile Enterotoxin of Escherichia coli in?

Heat-Labile Enterotoxin of Escherichia coli is in Phase 2 development. The single recorded trial, NCT00516659, is a completed Phase 2 study. The candidate is investigational and has not been approved by the FDA for any indication.

What clinical trials is Heat-Labile Enterotoxin of Escherichia coli in?

Heat-Labile Enterotoxin of Escherichia coli has been studied in one clinical trial, NCT00516659, also called the ETEC Logistics Trial (TREK). This completed Phase 2 study enrolled 201 healthy adult volunteers aged 18 years and older in the United States, Guatemala, and Mexico. It was randomized, double-blind, and placebo-controlled.

Is Heat-Labile Enterotoxin of Escherichia coli the same as LT?

Yes. Heat-Labile Enterotoxin of Escherichia coli is also known as LT, short for heat-labile enterotoxin. Both names refer to the same Valneva SE monoclonal antibody candidate studied in the Phase 2 ETEC Logistics Trial (TREK) for diarrhea.
