Partially-blind (Observer-blind) Study of Safety and Immunogenicity of Two Malaria Vaccines in Ghanaian Children

August 10, 2017 updated by: GlaxoSmithKline

A Partially-blind (Observer-blind) Study to Evaluate the Safety and Immunogenicity of 3 Different Vaccination Schedules With 2 GSK Biologicals' Candidate Plasmodium Falciparum Vaccines in Children Aged 5 to 17 Months Living in Ghana

This study will investigate the safety and immunogenicity of 2 candidate malaria vaccines administered according to 3 different vaccination schedules in 5 to 17 months old Ghanaian children. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be conducted in a partially blind fashion: it will be observer-blind as to which vaccine was administered, and open as to the vaccination schedule. One group of children on the 0, 1, 2-schedule will receive a Rabies vaccine as a control. One group on the same schedule will receive the RTS,S/AS02D experimental vaccine as an active comparator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Serious Adverse Events (SAEs)
Time Frame: From Day 0 to Month 10
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
From Day 0 to Month 10

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Any and Grade 3 Solicited Local Symptoms
Time Frame: During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses
Assessed solicited local symptoms were pain and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 swelling = swelling spreading beyond 20 millimeters (mm) of injection site.
During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms
Time Frame: During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses
Assessed solicited general symptoms were drowsiness, fever [defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)], irritability and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever higher than (>) 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.
During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses
Number of Subjects With Any Unsolicited Adverse Events (AEs)
Time Frame: During the 30-day (Days 0 - 29) post-vaccination period following each dose and across doses
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.
During the 30-day (Days 0 - 29) post-vaccination period following each dose and across doses
Titers for Anti-Circumsporozoite Protein of Plasmodium Falciparum (Anti-CS)
Time Frame: At Day 0, at Month 2, at Month 7 and at Month 10
Titers are presented as geometric mean titers (GMTs) and expressed in enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).
At Day 0, at Month 2, at Month 7 and at Month 10
Titers for Anti-Hepatitis B (Anti-HBs)
Time Frame: At Day 0 and at Month 2
