I did some digging and can’t for the life of me find that clinical trial I was thinking of so I might just be remembering it wrong, but I do know there’s a lot of interest in parasite-derived immunomodulatory molecules, which interestingly do often seem to be derived from helminth excretions or secretions.
This 2022 Frontiers in Parasitology article titled Immunomodulatory and biological properties of helminth-derived small molecules: Potential applications in diagnostics and therapeutics seems like a good review of the current situation.
You’re welcome!
But yeah I think derived drugs are the way to go in the long run, infecting someone with actual parasites can be a bit of a can of worms (pun intended) although not nearly as bad as it sounds like
