Clinical Trial of GX-I7 in Healthy Volunteers

Interleukin-7 (IL-7) is T cell growth factor that can be used for treating lymphopenia patients. GX-I7 is a protein drug recombining human IL-7 and hybrid Fc (hyFc). HyFc made by Genexine is composed of hinge-CH2 region of Immunoglobulin D (IgD) and CH2-CH3 region of Immunoglobulin G4 (IgG4). The recombined region is not exposed and each region's characteristics can reduce immunogenicity and improve the efficacy of drug. Consequently, it will be able to treat the patients with lymphopenia in effective ways.

This is the placebo of GX-I7 described above.
