Juvaris initiates Phase I influenza vaccine trial

Juvaris BioTherapeutics has initiated a Phase I clinical trial of its lead compound, JVRS-100. The trial will compare the safety, tolerability and immunogenicity of the JVRS-100 adjuvant co-administered with a commercial influenza vaccine compared to vaccine alone.

The randomized, double blind, controlled Phase I trial is expected to enroll 128 healthy subjects in four treatment cohorts. The study will evaluate a licensed trivalent, inactivated, split influenza vaccine with ascending dose levels of JVRS-100 compared to the vaccine alone. JVRS-100 will also be studied with reduced doses of the influenza vaccine to assess its effectiveness and vaccine dose-sparing effects.

Primary objectives of the study are to assess the safety and tolerability of the JVRS-100 adjuvant and its ability to enhance immune responses (both antibody and cellular immunity) to the influenza vaccine.

Grant Pickering, president and CEO of Juvaris, said: “This double blind trial will evaluate varying dose amounts of JVRS-100 and is designed to provide safety information, dose determination and the primary immunological response data used to determine efficacy for adjuvanted vaccines.”
