This study is designed to assess safety, tolerability, and pharmacokinetics (PK) of single ascending dose (SAD) of ABI-1179 in Part A in healthy participants and multiple-ascending doses (MAD) of ABI-1179 in Part B in participants seropositive for Herpes Simplex Virus Type 2 (HSV-2) with recurrent genital herpes. Effect of food will also be evaluated in Part A.
This exploratory trial will have three parts. Part A is a dose escalation part, Part B is an expanded safety and dose evaluation part, and Part C is a safety and immunogenicity evaluation part in individuals with recurrent HSV-2 genital herpes. Part A will focus on the safety evaluations, and in addition, vaccine-induced immune responses (specifically neutralizing antibodies) will also be analyzed to assess if there is a dose-response. Part B of the trial will expand the safety characterization for two dose levels of BNT163 selected based on Part A data and will also enable a more comprehensive assessment of the impact of pre-existing immunity to HSV-1 and -2 on the safety and immune responses to BNT163. Part C will evaluate safety and immunogenicity of BNT163 compared to a placebo in a three-dose regimen in subjects with a history of HSV-2 recurrent genital herpes.
The purpose of this study is to evaluate the effect of recombinant human heat shock protein 70-polyvalent peptide complex (HerpV) vaccine administration on recurring episodes of genital herpes by evaluating viral shedding before and after treatment.
The purpose of this study is to evaluate how well the vaccine is tolerated at sites where administrations are given and any effects it may have on subjects' wellbeing. The study will also test the ability of vaccine to cause particular immune responses in the body and evaluate the effect it has on herpes outbreaks
The purpose of this study is to generate safety and immunogenicity data and establish a proof-of-concept of clinical benefit of the mRNA-1608 vaccine candidate.
