Study summary

Patients will be enrolled in two stages:

  • Dose-escalation stage: Approximately 12-24 patients will be enrolled.
Read the detailed description

Detailed Description:

  • Dose-escalation stage : designed as classical 3+3 to determine MTD(Maximum tolerable dose), RP2D(Recommended Phase 2 Dose) and DLT(Dose-limiting toxicity)s to evaluate approximately four dose levels of GX-I7
  • pre-determined dose(Level I)\~ pre-determined dose(Level IV)
