TRIAL DESCRIPTION
Public title Phase II multi-centre study to evaluate efficacy, safety, and immunogenicity of GMZ2 candidate malaria vaccine in children aged 12 to 60 months
Official scientific title A phase II, randomized, controlled, double-blind, multi-centre study to evaluate the efficacy, safety, and immunogenicity of GMZ2 candidate malaria vaccine in Gabonese, Bukinabe, Ghanaian, and Ugandan children aged 12 to 60 months
Brief summary describing the background
and objectives of the trial
GMZ2 candidate malaria vaccine; phase IIb multicentred trial enrolling 1840 children aged 12 - 60 months in Gabon; Burkina Faso; Ghana and Uganda. This trial will primarily assess efficacy of the GMZ2 experimental vaccine and secondarily safety and immunogenicity. Humoral and cellular immune responses(quality and functionality)will be explored. GMZ2 experimental vaccine has successfuly undergone phase I safety testing in adults and children. (clintrial.gov NCT00397449,NCT00424944 & NCT00703066)

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person
allocating the participants to the intervention arms
Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Independent Statistician (LSHTM); Simple randomization using Computer software Sealed opaque envelopes Masking/blinding used

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental group Lyophilized recombinant Lactococcus lactis Hybrid GMZ2 [GLURP+MSP3] Three (3) doses of 100µg administered 28 days apart Day 0, 28 & 56 Intramuscular vaccine 920

ELIGIBILITY CRITERIA
List inclusion criteria List exclusion criteria Min age Max age Gender
1. Children aged 12 - 60 months inclusive at the time of the first dose 2. Healthy by medical history and physical examination 3. Signed or thumb-printed Informed Consent by guardian/parent. Where guardian/parent cannot sign, a witness will be asked to sign to indicate that the procedures were understood and consent was given. 4. Resident in the study villages during the whole clinical trial period 1. Symptoms, physical signs of disease that could interfere with the interpretation of the clinical trial results or compromise the health of the subjects if they were vaccinated 2. Immunosuppressive therapy (steroids, immune modulators or immune suppressors) within three (3) months prior recruitment. (for corticosteroids, this will mean prednisone, or equivalent, ¿ 0.5 mg/kg/day. Inhaled and topical steroids are allowed.) 3. Cannot be followed for any social, psychological or geographical reasons. 4. Use of any investigational drug or vaccine other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use up to the end of the child¿s participation in this clinical trial. 5. Suspected or known hypersensitivity to any of the vaccine components or to any vaccine. 6. Acute or chronic, clinically significant hepatic or renal functional abnormality. 7. Anaemia associated with clinical signs or symptoms of decompensation or haemoglobin < 7.0 g/dL. 8. Planned administration of a vaccine not foreseen by the trial protocol within 30 days of the first dose of vaccine. An exception, is the receipt of an EPI or licensed vaccine (measles, oral polio, Hib, meningococcal and combined diphtheria/ pertussis/ tetanus vaccines) which may be given 14 days or more before or after vaccination 9. Presence of chronic illness that, in the judgement of the investigator, would interfere with the study outcomes or pose a threat to the participant¿s health. 10. Administration of immunoglobulin and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period 11. History of surgical splenectomy. 12. Severe malnutrition at screening defined as weight for age Z-score less than 3 12 Months 60 Months Both

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome Efficacy Primary analysis will be done as soon after 6 months of follow-up have elapsed if at least 330 children have had an episode of malaria. In case the target number is not reached by 12 months, analysis will be carried out at 12 months.
