NCT03776994
Brief Summary:
The primary objective of the study is to evaluate the safety and immunogenicity of non-adjuvanted and adjuvanted monovalent VEE VLP Vaccine in healthy adults (ages 18-50 years) when administered via intramuscular (IM) injection at escalating doses of 2 μg, 10 μg, and 20 μg as a 2-dose primary series (Day 0, Day 28) with a Day 140 booster dose. The secondary objective of the study is to evaluate immunogenicity of the vaccine at the aforementioned time points
Detailed Description:
This Phase 1 dose escalation study will evaluate safety and immunogenicity of both non-adjuvanted and adjuvanted VEE VLP vaccine in three dose groups (2 μg, 10 μg, and 20 μg) given as a 2-dose primary series IM injection (Days 0 and Week 4 \[Day 28\]) followed by a booster dose injection (Week 20 \[Day 140\]). Each group will consist of 30 subjects, for a total of 90 study subjects. Each group of 30 subjects will be randomized to receive either non-adjuvanted vaccine (Subgroup A; n=15) or adjuvanted vaccine (Subgroup B; n=15). Subjects will be blinded to receiving the non-adjuvanted versus adjuvanted vaccine, but will not be blinded to the vaccine dosage. Enrollment will utilize a sentinel dose design, with only one subject receiving a vaccine dose the initial day, 2 subjects the following day, and 3 subjects the subsequent day, before proceeding with further enrollments in that group. Subjects in each Group will be randomized to receive the vaccine dose either without adjuvant (Subgroup A) or with adjuvant (Subgroup B).
