Study Summary

This is a Phase 1, open-label, dose-escalation clinical trial to evaluate the safety, reactogenicity, and immunogenicity of the Sm-p80+GLA-SE vaccine candidate in healthy adults between 18 and 55 years of age. Forty-five subjects will receive a series of three intramuscular injections 28 days apart with dose based on group. Five treatment groups, each including nine subjects, will receive three intramuscular (IM) injections of 0.5 mL of the designated study product on either Days 1, 29, and 57 or on Days 1, 29, and 180 (Table 1). Group A (unadjuvanted comparator) will receive 100 micrograms Sm-p80 alone on Days 1, 29, and 57, Group B (low dose standard schedule) will receive 10 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 57, Group C (mid dose delayed booster) will receive 30 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 180, Group D (mid dose standard schedule) will receive 30 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29, and 57, and Group E (high dose standard schedule) will receive 100 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 57. Study duration is approximately 20 months and will be conducted at one site in the US. Participant duration for subjects is 15 months. The primary objective is to assess the safety and reactogenicity following receipt of three doses of 1) 100 micrograms Sm- p80 (unadjuvanted), 2) 10 micrograms Sm-p80 + 5 micrograms GLA-SE, 3) 30 micrograms Sm-p80 + 5 micrograms GLA- SE, and 4) 100 micrograms Sm-p80 + 5 micrograms GLA-SE administered intramuscularly on Days 1, 29, and 57 and 5) 30 micrograms Sm-p80 + 5 micrograms GLA- SE administered on Days 1, 29, and 180.

Primary Outcome

An AE or suspected adverse reaction were considered an SAE if, in the view of either the principal investigator or the sponsor, resulted in any of the following outcomes: * Death, * A life-threatening AE, * Inpatient hospitalization or prolongation of existing hospitalization, * A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or * A congenital anomaly/birth defect. * Important medical events that may not have resulted in death, b
