Epetirimod (S-30563 or TAK-851) is an immunostimulant. The compound is structurally related to the marketed topical imidazoquinoline drug, imiquimod, an agonist of Toll-like receptor 7. Epetirimod was under development with Takeda Pharmaceutical as a topical treatment for cervical high-risk HPV infection and cervical dysplasia. Takeda has discontinued epetirimod development as it did not meet the predefined efficacy end points in a US Phase II trial.
