A new approach to treating life-threatening envenomation
Ophirex's investigational candidate varespladib is a first-of-its-kind oral rescue treatment for snakebite. Varespladib works by binding to and inactivating a key toxin present in the venom of more than 95% of snake species, meaning it will have broad applicability. Varespladib is being developed as an oral, portable capsule that can be taken immediately after a snakebite.

“The unifying characteristic of the people at Ophirex is our commitment to the mission—we are united by the urgent unmet need in snakebite treatment.”
A Mission-Oriented Team
Creating the first breakthrough in snakebite treatment in more than 100 years takes dedication and commitment. Ophirex is comprised of passionate professionals with diverse expertise, all focused on reducing lethality and disability from snakebite worldwide.
Scientific Breakthrough for
Snakebite Treatment
Ophirex was founded by Matthew R. Lewin, MD, PhD, an emergency physician and experienced expedition doctor with a PhD in neurophysiology, in collaboration with Jerry Harrison, a musician, producer and investor.
Dr. Lewin began to think about new ways to treat snakebite following the death of a researcher from snakebite while on expedition to Southeast Asia. The challenge is that the current standard of care – antivenom – needs to be administered intravenously in a hospital setting. In addition, the antivenom administered needs to match the snake species that caused the bite.
Dr. Lewin hypothesized that the right small molecule could neutralize the effects of a key snake venom toxin, reversing paralysis and resolving other toxicities. He worked on various solutions but knew he needed help bringing his ideas to fruition. Upon meeting Harrison, who asked a group of physician-scientists including Lewin if anyone had “any great ideas lying fallow,” Ophirex was born.
After conducting experiments in 2014 and 2015, Dr. Lewin published the first article describing the potential for varespladib as a field treatment for snakebite in 2016. He recognized then that a small-molecule approach that could be administered orally has the potential to address a significant need: the critical gap between the time when envenomation takes place and the hospital administration of antivenom.

“We are transforming the paradigm of snakebite treatment and challenging a century-old approach to saving lives.”
