The median time to response was 4.1 months (RANGE: 1.2–16.7 MONTHS) in the IMLYGIC® arm1

Continue treatment with IMLYGIC® for at least 6 months—

unless other treatment is required or until there are no injectable lesions to treat. Reinitiate IMLYGIC® treatment if new unresectable cutaneous, subcutaneous, or nodal lesions appear after a complete response.1

  • Oncovex (GM-CSF) Pivotal Trial in Melanoma (OPTiM) was a phase 3, multicenter, open-label study of 436 stage IIIB, IIIC, and IV patients (previously treated and untreated). Patients had injectable, unresectable melanoma and were randomized 2:1 to receive IMLYGIC® or GM‑CSF.1‑3
  • The Durable Response Rate (DRR) was 16.3% in the IMLYGIC® arm (48/295) and 2.1% in the GM-CSF arm (3/141) in the overall study population. The unadjusted relative risk was 7.6 (95% CI: 2.4, 24.1); P < 0.0001. The median time to response was 4.1 (range: 1.2 to 16.7) months in the IMLYGIC® arm.1,3
  • There was no statistically significant difference in overall survival (OS) between the IMLYGIC® and the GM-CSF arms.1
