In tiny trial, malaria drug combo cleared a stubborn tick-borne infection
60 Degrees Pharmaceuticals announced that all three patients in its expanded-use clinical trial for relapsing babesiosis were cured after treatment with a tafenoquine-containing regimen. This data, combined with findings from a 2024 Yale report, suggests a near 100% cure rate for immunosuppressed babesiosis patients when weekly tafenoquine is added to existing treatments. The company believes these results warrant a review of current babesiosis treatment guidelines, despite tafenoquine not being FDA-approved for this specific condition.
