Trial Outcomes & Findings for Safety Study of a Capsule-Conjugate Vaccine to Prevent Campylobacter-Caused Diarrhea (NCT NCT02067676)

NCT ID: NCT02067676

Last Updated: 2018-02-23

Results Overview

Vaccine safety will be assessed by evaluating post-vaccination local and systemic reactions through targeted physical exams, symptom surveys, and other adverse event (AE) monitoring. All subjects will be observed in the clinic for at least 30 minutes after receipt of the investigational product. Approximately 48 hours after vaccination, subjects will return to the Clinical Trials Center for observation and reporting of any local and/or systemic AEs. Seven days after vaccine administration, subjects will return to the Clinical Trials Center to review their memory aids with study personnel and to report any AEs. In addition to planned visits, if a subject experiences any unanticipated AE, the subject will be seen by one of the study investigators. All AEs will be coded for onset date, duration, severity, and potential relationship to the investigational product.

PRIMARY outcome

Timeframe: up to 7 days

Population: Rates of all AEs were analyzed by Pearson's Chi-square test (or Fisher's exact test if assumptions were not met for Pearson's Chi-square) to compare groups.

Vaccine safety will be assessed by evaluating post-vaccination local and systemic reactions through targeted physical exams, symptom surveys, and other adverse event (AE) monitoring. All subjects will be observed in the clinic for at least 30 minutes after receipt of the investigational product. Approximately 48 hours after vaccination, subjects will return to the Clinical Trials Center for observation and reporting of any local and/or systemic AEs. Seven days after vaccine administration, subjects will return to the Clinical Trials Center to review their memory aids with study personnel and to report any AEs. In addition to planned visits, if a subject experiences any unanticipated AE, the subject will be seen by one of the study investigators. All AEs will be coded for onset date, duration, severity, and potential relationship to the investigational product.

Timeframe: Study Days 0-56

Population: Campylobacter jejuni conjugate vaccine (1CJCV1); antibody-secreting cell(s) (ASCs); Peripheral blood mononuclear cell (PBMCs)

Primary immunologic parameters, serum samples were assessed for the antibody titers against Campylobacter jejuni conjugate vaccine1 (CJCV1) using ELISA (enzyme-linked immunosorbent assay) based methods. Antibody-secreting cell(s) (ASCs): \>0.5 per 10(6) Peripheral blood mononuclear cell (PBMCs) in the baseline sample. When the number of baseline ASCs is less than 0.5 per 10(6) PBMCs, a subject was considered a responder if the post-vaccination value was greater than 1.0 per 10(6) PBMCs. ((6) is superscript). 1. = Seroconversion was defined as \>4fold increase in endpoint titer between pre- and post-vaccine samples and a post-vaccine reciprocal titer \>10. 2. = Response is defined as a \>2fold increase over the baseline value of ASC per 10(6) PBMCs, when the number of ASCs is \>0.5 per 10(6) PBMCs in the baseline sample. When the number of baseline ASCs is less than 0.5 per 10(6) PBMCs, a subject was considered a responder if the post-vaccine value was greater than 1.0 per 10(6) PBMCs.

Timeframe: Study Days 0-56

Anti-CPS IgG ASC Responses - GMTs with 95% CI. A positive immunoglobulin A (IgA)-ASC response will be defined as a \> twofold increase over the baseline value of the ASCs per 10\^6 peripheral blood mononuclear cells (PBMCs). A subject will be considered a responder if the post-vaccination value is greater than 2.0 per 10\^6 PBMCs. Blood samples will also be utilized to explore in vitro production of interferon (IFN)-(gamma).

Timeframe: Study Days 0-56

Anti-CRM\^197 IgG ASC Responses - GMTs with 95% CI. A positive immunoglobulin A (IgA)-ASC response will be defined as a \> twofold increase over the baseline value of the ASCs per 10\^6 peripheral blood mononuclear cells (PBMCs). A subject will be considered a responder if the post-vaccination value is greater than 2.0 per 10\^6 PBMCs. Blood samples will also be utilized to explore in vitro production of interferon (IFN)-(gamma).
