About this study
Official title: A Phase Ib Randomised, Controlled, Single-blind Study to Assess the Safety, Immunogenicity of the Malaria Vaccine Candidate R21 With Matrix-M1 Adjuvant in West African Adult Volunteers
This is a study in which healthy adult volunteers will be given either an experimental Malaria vaccine or a saline control vaccine.
Each volunteer will receive three vaccinations in total. Volunteers will be randomly allocated to one of two groups:
Group 1 will receive a low dose of the Malaria vaccine on days 0, 28, and 56. Group 2 will receive a saline solution on days 0, 28, and 56.
Read the detailed description
A randomised, controlled, single-blind clinical trial to evaluate the safety and immunogenicity of the malaria vaccine candidate regime of three (3) doses of R21/Matrix-M1 compared with placebo, in healthy West African adult volunteers living in a malaria-endemic area.
The study will take place at the Centre National de Recherche et de Formation sur la Paludisme (CNRFP)/Unite de Recherche Clinique de Banfora (URC-B). Trial participants will be drawn from the Banfora Health Demographic system, which covers a total population of 30, 000.
Community sensitisation will be undertaken to engage the community with the study and recruit volunteers for participation in the study. The CNRFP study team will hold local community meetings and explain the study to the potentially eligible adult volunteers. During these meetings the investigators will explain the following: the need for a vaccine; the current status of vaccine development (including the fact that this is likely to be a prolonged process); the study screening and informed consent procedure; risks of vaccination and the unproven benefits of vaccination. It will be stressed that these are experimental vaccine regimens and cannot be guaranteed to provide protection, and that it will therefore still be necessary to seek treatment for possible malaria even after vaccination and they should continue to use other protective measures such as bed nets. It will be explained that to aid identification, a photograph of the volunteer will be taken if they are eligible to be enrolled in the trial.
After this meeting, based on the list of adults of suitable age for participation in the trial drawn from the DSS database, volunteers will be asked to participate in a public lottery that is made to randomly select participants who will be invited for a screening visit. All proposed volunteers thus selected will be invited to the Banfora clinical trials centre for the screening visit.
The Volunteer Information Sheet (VIS) will contain detailed information about the study and will be distributed to the proposed volunteers. The investigators will endeavour to ensure that all volunteers fully understand the risks. Any volunteer who appears to have less than complete understanding will be considered unable to give consent. If unable to sign, the volunteer will be asked to thumbprint the consent form in the presence of an impartial witness who will be present during the screening procedures and will countersign the consent form. Fully consented volunteers will undergo the full screening procedures. This consists of medical history, physical examination, and blood sampling for screening tests.
Volunteers will be randomised to receive either three (3) doses of R21/ Matrix-M1 or placebo (normal saline) as control. Simple randomisation into the study groups will be done by an independent statistician based at the University of Oxford. A randomisation code list will be generated by the independent statistician and its use guided by a clear Standard Operating Procedure (SOP). Allocation concealment will be employed by use of opaque sealed envelopes. As this is a single-blind clinical trial design, the laboratory scientists will be blinded to vaccine allocation until the end of the study.
Each volunteer will be monitored for one hour (or longer if necessary) after each vaccination. Each volunteer will be visited at home daily for 6 days after each vaccination (Days 0, 28, and 56) by a field worker for assessment and recording of any solicited and unsolicited AEs in diary cards. If necessary the volunteer will continue to be seen regularly until any observed AEs have resolved or stabilised. Scheduled visits at the CNRFP will be on Days 0, 7, 28, 35, 56, 63, 84, and 140. All volunteers will be followed up to Day 140 post-first vaccination for adverse events.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a study in which healthy adult volunteers will be given either an experimental Malaria vaccine or a saline control vaccine.
Each volunteer will receive three vaccinations in total. Volunteers will be randomly allocated to one of two groups:
Group 1 will receive a low dose of the Malaria vaccine on days 0, 28, and 56. Group 2 will receive a saline solution on days 0, 28, and 56.
Detailed description
A randomised, controlled, single-blind clinical trial to evaluate the safety and immunogenicity of the malaria vaccine candidate regime of three (3) doses of R21/Matrix-M1 compared with placebo, in healthy West African adult volunteers living in a malaria-endemic area.
The study will take place at the Centre National de Recherche et de Formation sur la Paludisme (CNRFP)/Unite de Recherche Clinique de Banfora (URC-B). Trial participants will be drawn from the Banfora Health Demographic system, which covers a total population of 30, 000.
Community sensitisation will be undertaken to engage the community with the study and recruit volunteers for participation in the study. The CNRFP study team will hold local community meetings and explain the study to the potentially eligible adult volunteers. During these meetings the investigators will explain the following: the need for a vaccine; the current status of vaccine development (including the fact that this is likely to be a prolonged process); the study screening and informed consent procedure; risks of vaccination and the unproven benefits of vaccination. It will be stressed that these are experimental vaccine regimens and cannot be guaranteed to provide protection, and that it will therefore still be necessary to seek treatment for possible malaria even after vaccination and they should continue to use other protective measures such as bed nets. It will be explained that to aid identification, a photograph of the volunteer will be taken if they are eligible to be enrolled in the trial.
After this meeting, based on the list of adults of suitable age for participation in the trial drawn from the DSS database, volunteers will be asked to participate in a public lottery that is made to randomly select participants who will be invited for a screening visit. All proposed volunteers thus selected will be invited to the Banfora clinical trials centre for the screening visit.
The Volunteer Information Sheet (VIS) will contain detailed information about the study and will be distributed to the proposed volunteers. The investigators will endeavour to ensure that all volunteers fully understand the risks. Any volunteer who appears to have less than complete understanding will be considered unable to give consent. If unable to sign, the volunteer will be asked to thumbprint the consent form in the presence of an impartial witness who will be present during the screening procedures and will countersign the consent form. Fully consented volunteers will undergo the full screening procedures. This consists of medical history, physical examination, and blood sampling for screening tests.
Volunteers will be randomised to receive either three (3) doses of R21/ Matrix-M1 or placebo (normal saline) as control. Simple randomisation into the study groups will be done by an independent statistician based at the University of Oxford. A randomisation code list will be generated by the independent statistician and its use guided by a clear Standard Operating Procedure (SOP). Allocation concealment will be employed by use of opaque sealed envelopes. As this is a single-blind clinical trial design, the laboratory scientists will be blinded to vaccine allocation until the end of the study.
Each volunteer will be monitored for one hour (or longer if necessary) after each vaccination. Each volunteer will be visited at home daily for 6 days after each vaccination (Days 0, 28, and 56) by a field worker for assessment and recording of any solicited and unsolicited AEs in diary cards. If necessary the volunteer will continue to be seen regularly until any observed AEs have resolved or stabilised. Scheduled visits at the CNRFP will be on Days 0, 7, 28, 35, 56, 63, 84, and 140. All volunteers will be followed up to Day 140 post-first vaccination for adverse events.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing R21/Matrix-M1 and Saline in people with Malaria, run by University of Oxford at 1 site in Burkina Faso.
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 7 inclusion and 19 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 6 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Burkina Faso. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 6 Nov 2019). 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?
Safety and Tolerability of Administration of R21/Matrix-M1 Assessed by the Occurrence of Solicited Local and Systemic Adverse Events. (time frame: Assessment of solicited AEs in the first 7 days post vaccination.). The study lists 4 primary outcomes in all. 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 NCT02925403, which also lists 38 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 6 Nov 2019.
