About this study

Official title: A Phase I Trial of PFCSP DNA/MVA.CSO Prime/Boost Vaccine in Mampong, Ghana

The purpose of this study is to evaluate the safety, tolerability, and effectiveness of 2 doses of a malaria vaccine (DNA) followed by a dose of another type of malaria vaccine (MVA) given as a "booster." Forty-eight adults in Ghana, ages 18-50 years, will participate for 17 months. They will be randomly assigned to 1 of 4 treatment groups. Group 1 will receive the DNA malaria vaccine at months 0 and 1, and the booster at month 7. Group 2 will receive a rabies vaccine at months 0 and 1, and an injection containing no vaccine at month 7. Group 3 will receive the DNA malaria vaccine at months 5 and 6, and the booster at month 7. Group 4 will receive the rabies vaccine at months 5 and 6, and an injection containing no vaccine at month 7. Blood samples and information regarding health problems that may occur after vaccination will be collected.

Read the detailed description

The purpose of this study is to assess the safety, tolerability, and immunogenicity of immunization with 2 doses of the PfCSP DNA vaccine (given 1 month apart) followed by a single dose of MVA.CSO (given either 1 month or 6 months later) when administered to healthy, malaria semi-immune adult volunteers. This Phase 1, randomized study conducted at Tetteh Quarshie Memorial Hospital will enroll 48 healthy volunteers, ages 18 to 50 years. Twenty four volunteers will initially be recruited and randomized to Groups 1 and 2. During Months 4 and 5 of the study, another 24 volunteers will be recruited and randomized to Groups 3 and 4. Group 1 will receive the DNA malaria vaccine intramuscularly (IM) at months 0 and 1, and the MVA malaria vaccine intradermally (ID) at month 7. Group 2 will receive a rabies vaccine IM at months 0 and 1, and a normal saline injection ID at month 7. Group 3 will receive the DNA malaria vaccine IM at months 5 and 6, and the MVA malaria vaccine ID at month 7. Group 4 will receive the rabies vaccine IM at months 5 and 6, and a normal saline injection ID at month 7. Blood samples will be collected at intervals for safety and immunogenicity studies. Vaccine safety will be monitored until 10 months after the final dose. At the conclusion of the study, volunteers randomized to Groups 1 and 3 will have the option of receiving the rabies vaccine. The primary study objectives are to: (1) assess the safety and tolerability of immunization with two doses of PfCSP DNA followed by one dose of MVA.CSO in healthy, malaria semi-immune adult volunteers when given at intervals of 0, 1, and 2 months or at 0, 1, and 7 months; (2) evaluate whether the PfCSP DNA/MVA.CSO prime/boost vaccine regimen induces PfCSP-specific immune responses, as assessed by IFN-gamma ELISPOT assay, over background responses; and (3) evaluate whether extending the interval between the second dose of PfCSP DNA and MVA.CSO from 1 month to 6 months is associated with higher levels of PfCSP specific T cell responses in semi-immune adults. The secondary study objective is to evaluate whether extending the interval between the second dose of PfCSP DNA and MVA.CSO from 1 month to 6 months is associated with higher levels of humoral immunity by ELISA and IFAT in semi-immune adults. The principal outcome measure will be the incidence of any vaccine related adverse event, abnormal lab values, and local or systemic reactions. An additional outcome variable for the remaining primary objectives is the results of the IFN-gamma ELISPOT assay at 1 week after administration of MVA.CSO. This study is planned to be the first of multiple clinical trials designed to test malaria vaccines in adults, children, and infants in endemic regions of Ghana.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MVA-CSO Vaccine and PfCSP DNA (VCL-2510) Vaccine in people with Plasmodium Falciparum Malaria, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in 2 countries.

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 24 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: withdrawn, as of the sponsor's last update on 23 Jan 2019. 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 United States, 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 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.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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.

Where can I read the original study information?
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 23 Jan 2019.
