Descriptive Information
Brief Title  ICMJE Immunogenicity of Seasonal Influenza by Delivery Directly to Ileum
Official Title  ICMJE An Open Label Phase I Substudy to Evaluate the Safety and Ability to Enhance Immunogenicity of VXA-A1.1 by Delivery Directly to the Ileum Using the InteliSite Companion Capsule in Healthy Adult Males
Brief Summary the purpose of the study is to determine the safety and tolerability of VXA-A1.1, an adjuvanted adenoviral based influenza vaccine, when delivery is targeted to the ileum, using a radio controlled capsule. The secondary objective is to evaluate the immune response (cellular and humoral) of two doses of VXA-A1.1 oral vaccine.
