NCT02244372

Brief Summary

The investigators performed randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of Cordyceps sinensis mycelium culture extract (Paecilomyces hepiali, CBG-CS-2) on promotion of immunity. The investigators measured promotion of immunity parameters , including Cytotoxicity, Cytokine (IL-4, IL-6, IL-12, IFN-γ, TNF-α), hs-CRP, antibody titer, and upper respiratory tract infection(URI)

Outcome Measures

Primary Outcomes (1)

  • Changes in Cytotoxicity

    Cytotoxicity was measured in study visit 1(0 week), visit 2(4 week) and visit 3(8 week). cytotoxicity was measured by NK cell activity. Cytotoxicity (%) = (experimental release - spontaneous release) / (maximum release - spontaneous release) x 100

    4, 8 weeks

Secondary Outcomes (2)

  • Changes in Cytokine(IL-4, IL-6, IL-12, IFN-γ, TNF-α)

    4, 8 weeks

  • Changes in hs-CRP

    4, 8 weeks
