If you have a dog or cat, chances are you’ve given your pet a flavored chewable tablet for tick prevention at some point. What if you could take a similar pill to protect yourself from getting Lyme disease?

Tarsus Pharmaceuticals is developing such a pill for humans—minus the tasty flavoring—that could provide protection against the tick-borne disease for several weeks at a time. In February, the Irvine, California–based biotech company announced results from a small, early-stage trial showing that 24 hours after taking the drug, it can kill ticks on people, with the effects lasting for up to 30 days.

“What we envision is something that would protect you before the tick would even bite you,” says Bobby Azamian, CEO of Tarsus.
