Summary

This expanded access program provides tafenoquine, an antimalarial drug, to immunocompromised patients with persistent babesiosis (a tick-borne illness) who haven't gotten better with standard treatments. Participants take the drug daily for 4 days, then weekly until they test negative for the parasite and symptoms resolve. The goal is to offer a potential treatment option for those at higher risk of complications.
