TRIAL DESCRIPTION
Public title TRAP VAC TRIAL
Official scientific title Safety and Immunogenicity of Heterologous Prime-Boost with the Candidate Malaria Vaccines AdCh63 ME-TRAP and MVA ME- TRAP in Healthy Adults in a Malaria Endemic Area
Brief summary describing the background
and objectives of the trial
This is a phase Ib study to assess safety & reactogenicity and evaluate the immunogenicty of Heterologous Prime-Boost Candidate Malaria Vaccines AdCh63 ME-TRAP and MVA ME- TRAP in Healthy adults in Kilifi - Kenya. The primary objective is to obtain preliminary data of AdCh63 ME-TRAP followed by MVA ME-TRAP in males in Kenya. The secondary objective is to compare intra-muscular and intra-dermal MVA ME-TRAP routes.

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 Screened participants will be allocated a sequential study ID number. That study ID number will correspond to the specific treatment allocation which will be randomly allocated to either group 1 as A1 or B1 or group 2 as A2 or B2. Block randomisation, computed in five blocks of six distributing subject into two groups at 1:2 ration (group 1 = 10 subject, group2 = 20 subject) Sealed envelopes. Independent statistician will generate randomisation list and print onto allocation cards and sealed. Sealed envelopes labeled wtih sequential study ID will be opened by subjects when eligible Open-label (masking not used)

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental group Group2 Day 0 High dose AdCh63 ME-TRAP followed by day 63 MVA ME-TRAP AdCh63 ME-TRAP at 5x10 power 10 vp then Single intramuscular dose for ADCh63 ME-TRAP. High dose AdCh63 ME-TRAP intramuscularly followed by MVA ME-TRAP given either IM (10) or ID (10) 20
Experimental group Group1 Day 0 low dose AdCh63 ME-TRAP followed by day 63 MVA ME-TRAP AdCh63 ME-TRAP at x10 power 10 vp then Single intramuscular dose for ADCh63 ME-TRAP. Low dose AdCh63 ME-TRAP intramuscularly followed by MVA ME-TRAP given either IM (5) or ID (5) 10
