Man’s⁢ Snake⁢ Venom Injections Could Lead to‍ Universal Antivenom

For 18 years, Tim fried, ‍a⁣ 57-year-old former truck mechanic, has been⁣ deliberately injecting himself with snake venom in an effort that may lead to a universal antivenom.⁣ His unusual self-experimentation has drawn the⁢ attention of‍ biotechnology ⁢researchers seeking a broader defense against deadly ⁣snakebites.

The Experiment

Fried began his endeavor with the goal of building immunity to snake venom after handling snakes. He subjected himself‍ to bites from some⁢ of the world’s most dangerous snakes, including cobras, black mambas, ⁣and taipans. Initially, a pair of Egyptian cobra bites put him in a coma. Despite the risks, Fried persisted, driven by the potential to contribute to the development of life-saving therapeutics.

over nearly two decades, Fried estimates he has been⁤ bitten more than 200 times and administered venom from ⁤over 700 snakes.

global Snakebite Crisis

Snakebites are a significant global health problem, ⁣with more than 400,000 incidents occurring annually, primarily in Africa, Asia, and Latin⁣ America. These incidents often result in ⁤amputations, blindness, and debilitating ulcers. The World Health Organization estimates⁤ that snakebites cause approximately 140,000 deaths ‍each ⁣year.

The complexity of snake venom poses a significant challenge to ⁢treatment. With 650 known⁢ species of venomous snakes,and variations in‍ venom composition even within the same species depending on geographic location,administering the correct antivenom can ⁢be difficult,leading to⁢ severe and lasting health consequences.

Biotech Intervention

In 2017, Senti⁣ Biosciences CEO Jacob Glanville learned of Fried’s story through a ⁣newspaper article. Intrigued, Glanville contacted fried and proposed a collaboration to ⁤develop broadly effective antibodies against various snake ⁤venoms using Fried’s blood.

The approach targets common elements across different snake venoms,‍ aiming to create a universal ⁢antivenom. “Snake’s poison is different⁣ for ⁢each species,so both detoxifications should be different,but if you target all the parts that are common to all snakes,you can ‍develop an ⁢extensively used antidote,” Glanville said.

Promising Results

Glanville’s research team extracted antibodies from Fried’s blood and conducted animal experiments, which showed promising results against a range of venoms. In‍ mouse studies, an antivenom cocktail based⁣ on Fried’s blood demonstrated complete effectiveness against 13 of 19 elapid snake venoms tested – elapids include cobras ⁢– ⁤classified by the WHO‍ as among the world’s deadliest.The cocktail showed partial effectiveness (20-40%) against the other six.

“It ⁢is unprecedented,” Glanville said of ⁣the results.⁢ “There is a possibility of being effective for the elapid’s poison without an antidote.”

Future Research

While‍ further research and clinical trials are necessary before the antivenom can ⁢be commercialized, ⁣the findings offer hope for saving countless lives.⁤ Researchers plan to develop two primary antivenom cocktails targeting elapid ⁤and ‍viperid snake venoms.

“I think I ⁤have been waiting for this,” Fried said of the collaboration.

The findings were⁣ published in the journal Cell.
