Trial Outcomes & Findings for A Study to Evaluate the Safety and Immunogenicity of a Candidate Ebola Vaccine in Children (NCT NCT02548078)

NCT ID: NCT02548078

Last Updated: 2018-05-03

Results Overview

Solicited general symptoms assessed included: fatigue, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], gastrointestinal symptoms \[nausea, vomiting, diarrhoea and/or abdominal pain\], headache, drowsiness, irritability/fussiness and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 fatigue/headache/drowsiness/gastrointestinal symptoms = fatigue/headache/drowsiness/gastrointestinal symptoms that prevented normal activity. Grade 3 fever = temperature \> 39.5°C. Grade 3 irritability/fussiness = crying that couldn't be comforted. Grade 3 loss of appetite = not eating at all. Related = symptom assessed by the investigator as related to the vaccination. Solicited general symptoms, for this endpoint, were assessed in subjects aged 1-5 years, 6-12 years and 13-17 years. Symptoms with no values were not assessed for those specific age groups.

PRIMARY outcome

Timeframe: During a 7-day follow-up period after each vaccination (i.e. the day of vaccination and 6 subsequent days)

Population: The analysis was performed on the Total Vaccinated Cohort, which included all subjects with at least one vaccine administration documented, who had their symptom sheets filled in.

Assessed solicited local symptoms included: pain and swelling at the injections site. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = crying at limb movement/spontaneous pain.Grade 3 swelling = swelling extending on a surface higher than (\>) 30 millimeters (mm). Solicited local symptoms, for this endpoint, were assessed in all subjects, in both groups.

PRIMARY outcome

Timeframe: During the 30-day follow-up period after each vaccination (i.e. the day of vaccination and 29 subsequent days)

Population: The analysis was performed on the Total Vaccinated Cohort, which included all subjects with at least one vaccine administration documented.

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Unsolicited adverse events, for this endpoint, were assessed in all subjects, in both groups.

Population: The analysis was performed on the Total Vaccinated Cohort, which included all subjects with at least one vaccine administration documented and with available results at the Screening time-point.

Haematological parameters assessed included: complete blood count (red blood cells \[RBC\], neutrophils, lymphocytes, white blood cells \[WBC\], haemoglobin, as well as differential count and platelet count for all subjects, in both groups. Reference range indicators used were: high, low, normal.

Population: The analysis was performed on the According-To-Protocol (ATP) cohort for analysis of immunogenicity, which included all evaluable subjects who complied with the protocol requirements and procedures and for whom data concerning immunogenicity endpoint measures were available.

Anti-GP EBOV antibodies were expressed as Geometric Mean Titers (GMTs), as measured by the Enzyme-Linked Immunosorbent Assay (ELISA) and assessed in all subjects, in both groups.
