A Study of Three Different Doses of VAC52416 (ExPEC10V) in Adults Aged 60 to 85 Years in Stable Health
June 4, 2026 updated by: Janssen Research & Development, LLC
A Randomized, Observer-blind, First-in-Human Phase 1/2a Study to Evaluate the Safety, Reactogenicity and Immunogenicity of Three Different Doses of VAC52416 (ExPEC10V) in Adults Aged 60 to 85 Years in Stable Health
The purpose of this study is to assess the safety, reactogenicity, and immunogenicity of 3 different doses of ExPEC10V and to select the optimal dose for further clinical development (Cohort 1).
Cohort 2 is aimed to expand the dataset supporting the short- and long-term safety and immunogenicity of the optimal dose of ExPEC10V, selected from the primary analysis results of Cohort 1. Cohort 2 will include participants in stable health with a history of urinary tract infection (UTI) in the past 5 years and will be included in the study to support the plan for late stage development of ExPEC vaccine.

Detailed Description
ExPEC10V (JNJ-69968054) is a 10-valent vaccine candidate in development for prevention of invasive extraintestinal pathogenic Escherichia coli (ExPEC) disease (IED) in adults 60 years of age and older.
ExPEC10V consists of O-antigen polysaccharides (PSs) of the ExPEC serotypes O1A, O2, O4, O6A, O8, O15, O16, O18A, O25B and O75 separately bioconjugate to the carrier protein, a genetically detoxified form of exotoxin A (EPA) derived from Pseudomonas aeruginosa.
Since, mechanism of action of conjugate vaccines in prevention of invasive disease is not expected to be affected by antibiotic resistance mechanisms, ExPEC10V vaccine may provide protection against IED caused by drug resistant and susceptible ExPEC serotypes.
The study consists of two cohorts.
Cohort 1 is comprised of three periods: a screening period (28 days), an observer-blind follow-up period (181 days) with vaccination on Day 1, and an open-label long term follow up (LTFU) period (from Day 182 until 5 years [Day 1826] post-vaccination).
Cohort 2 is also comprised of three periods: a screening period (28 days), a double-blind follow-up period (181 days) with vaccination on Day 1, and a double-blind LTFU period (from Day 182 until 1 years [Day 366] post-vaccination).
The end of Cohort 1 is considered as the Year 5 visit (Day 1826) for the last participant.
The end of Cohort 2 is considered as the Year 1 visit (Day 366) for the last participant.
Key immunogenicity assessments will include the assessment of ExPEC10V and ExPEC4V serotype-specific total immunoglobulin G antibody levels elicited by the vaccine and ExPEC10V and ExPEC4V serotype-specific functional antibodies.
Key safety assessments include solicited local and systemic AEs, unsolicited AEs, SAEs, physical examinations, vital sign measurements, and, for Cohort 1 only, clinical laboratory tests.
The total duration of the study is up to 5 years.

An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly/birth defect; suspected transmission of any infectious agent via a medicinal product or medically important.
