Key studies

  • Kaposi sarcoma: two nasal schedules: Early responses were not confirmed in the later placebo-controlled trial. (source)
  • Kaposi sarcoma: negative phase 3: IM862 did not beat placebo and may have accelerated progression. (source)
  • Kidney cancer: no tumor responses: High nasal doses produced no objective cancer responses. (source)
  • Prostate cancer: no clear benefit: IM862 did not prolong time to PSA progression. (source)
  • Before abdominal cancer surgery: Fewer complications were reported, with important reporting errors. (source)
  • Skin and soft-tissue wound trial: A small blinded trial reported faster wound healing. (source)
