About this study

Official title: 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.

Read the 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 being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With Serious Adverse Events (SAEs)

    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.

    Measured: From Day 0 to Month 10

Secondary outcomes (5)
  1. Number of Subjects With Any and Grade 3 Solicited Local Symptoms

    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.

    Measured: During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses

  2. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms

    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.

    Measured: During the 7-day (Days 0 - 6) post-vaccination period following each dose and across doses

  3. Number of Subjects With Any Unsolicited Adverse Events (AEs)

    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.

    Measured: During the 30-day (Days 0 - 29) post-vaccination period following each dose and across doses

  4. Titers for Anti-Circumsporozoite Protein of Plasmodium Falciparum (Anti-CS)

    Titers are presented as geometric mean titers (GMTs) and expressed in enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).

    Measured: At Day 0, at Month 2, at Month 7 and at Month 10

  5. Titers for Anti-Hepatitis B (Anti-HBs)

    Titers are presented as geometric mean titers (GMTs) and expressed in milli-international units per milliliter (mIU/mL).

    Measured: At Day 0 and at Month 2

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GSK Biologicals' candidate Plasmodium falciparum malaria vaccine 257049 and Rabipur in people with Malaria, run by GlaxoSmithKline at 2 sites in Ghana.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Ghana. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Feb 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects With Serious Adverse Events (SAEs) (time frame: From Day 0 to Month 10). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00360230, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Feb 2018.
