Study of Sting Challenge and Serological Responses to Jack Jumper Venom Immunotherapy With Inulin as Adjuvant (Jumpvax)

Summary

The purpose of this study is to assess the potential use of delta-inulin as an adjuvant to facilitate the desired immune response to Jack Jumper Ant (JJA) venom with a lower dose of venom, thus reducing adverse reactions, venom requirements and costs of treatment. Specifically we aim to compare outcomes of in-hospital JJA sting challenges and JJA venom specific IgE, and IgG4 responses to semi-rush JJA VIT at maintenance doses of 25 and 50 mcg of JJA venom, with and without delta-inulin adjuvant.
