Further Details

Primary Outcome Measures:

  • Rate of Relapse-free Survival at 18 months.

Secondary Outcome Measures:

  • Safety
  • NY-ESO-1 immunity
  • Relapse-free Survival and Overall Survival

Eligible participants are randomly allocated to a treatment arm. Treatment involves four intramuscular (into a muscle) injections (1 injection every 4 weeks x 3, plus 1 injection at 6 months). Participants are assessed for recurrence of melanoma, safety and immune responses (by blood test) over the 18 month study period. Off study, their own doctor will follow them for melanoma recurrence and survival.
