If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.

Mechanism of action

Imiquimod binds to TLR7 on immune cells, triggering production of interferon-alpha and other cytokines that enhance antiviral and anti-tumor immunity. This immune activation helps the body's own defenses clear human papillomavirus (HPV) infections and eliminate abnormal skin cells. The drug is applied topically, concentrating immune stimulation at the site of lesions.
