Official title
Phase I, Randomized, Observer-blinded, 3-part, Dose Escalation and Expanded Safety and Dose Evaluation Trial to Evaluate the Safety, Tolerability, and Immunogenicity of an Investigational Prophylactic Vaccine for the Prevention of Genital Lesions Caused by Herpes Simplex Virus (HSV)-2 and Potentially HSV-1
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 participants with a history of HSV-2 recurrent genital herpes.
