Developing a treatment for snakebite envenoming using varespladib.

Development of Intravenous Varespladib, a Phospholipase A2 Inhibitor, for the Treatment of Snakebite Envenoming

NIH-funded research Ophirex, INC. · NIH-10932399

This study is testing a new treatment called varespladib to see if it can help people who have been bitten by venomous snakes by reducing the harmful effects of the snake venom, especially when regular antivenoms don't work well.

What this research studies

This research focuses on the development of varespladib, a potent inhibitor of a specific toxin found in snake venom known as secretory phospholipase A2 (sPLA2). The study aims to evaluate the effectiveness of varespladib in treating patients who have been bitten by venomous snakes, particularly in reducing the severe toxic effects associated with snakebite envenoming. By inhibiting sPLA2, the research seeks to improve patient outcomes and potentially save lives, especially in cases where traditional antivenoms are ineffective. The approach includes both preclinical and clinical evaluations to determine the safety and efficacy of varespladib in human subjects.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who have experienced a snakebite from a venomous species.

Not a fit: Patients who have not been bitten by a venomous snake will not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly reduce mortality and disability caused by snakebites.

How similar studies have performed: Previous experimental studies have shown promising results with similar approaches, indicating potential for success in human applications.
