Study to Evaluate Safety and Tolerability of GX-I7 in Patients With Locally Advanced or Metastatic Solid Tumors

Phase 1
Completed
Conditions
Locally Advanced or Metastatic Solid Tumors
Interventions
Registration Number
NCT03478995
Lead Sponsor
Genexine, Inc.
Brief Summary

Patients will be enrolled in two stages:

* Dose-escalation stage: Approximately 15-30 patients will be enrolled.

* Dose-expansion stage: 6-12 patients will be enrolled. Dose-escalation slots will be filled first, then dose-expansion slots.

Detailed Description

* Dose-escalation stage : designed as classical 3+3 to determine MTD or RP2D to evaluate approximately GX-I7.

* Dose-expansion stage : designed to enroll additional 6-12 patients to acquire additional safety and pharmacodynamic data to more fully inform the dose selection for RP2D
