Background:
Researchers are looking for new ways to control and eradicate malaria. They want to test vaccines to block malaria transmission in adults in Mali. These vaccines work by inducing antibodies in a person. The antibody is then taken up with blood by a mosquito that bites the person. This blocks parasite development in the mosquito. This stops malaria transmission to another person.
Objective:
To test the safety, reactogenicity, immunogenicity, and transmission-blocking activity of the vaccines Pfs25M-EPA and Pfs230D1M-EPA with AS01 in Malian adults.
Eligibility:
Healthy Malians ages 18-50 living in certain areas in Mali who:
Are not pregnant or breastfeeding
Are not infected with HIV, Hepatitis B and Hepatitis C
Do not have evidence of immunodeficiency
Do not have history of severe allergic reaction or anaphylaxis
Design:
Participants will be screened with:
Medical history
Physical exam
Malaria Comprehension Exam
Blood and urine tests
Electrocardiogram (for participants in certain study groups)
Participants will be randomly assigned to a study group.
Participants will be monitored for 12-16 months. For the first 7 months, they will have between 1 and nine visits a month. The number depends on the month and on what group they are in. For the rest of the months, they will have 1 monthly visit.
Each visit includes a physical exam. Most include blood tests.
Participants will get 3 doses of a study or comparator vaccine. They get the vaccine through an injection in the upper arm. This occurs at their first visit, then 1 month later, and then 5 months later.
Participants will be followed for at least 6 months after the last vaccine.
If participants develop an injection site rash or reaction, photographs may be taken of the site.
A vaccine to interrupt malaria transmission (VIMT) would be a valuable tool for local elimination or eradication of this disease, and may contain components that block transmission to mosquitoes (such as Pfs25 or Pfs230) or that prevent human infection (such as the vaccine RTS,S). Pfs25 and Pfs230, surface antigens of zygotes and ookinetes (and gametocytes for Pfs230) in the mosquito stage of P. falciparum, are the lead candidates for a malaria transmission blocking vaccine (TBV). Recombinant Pfs25M and recombinant Pfs230D1M have each been conjugated to P. aeruginosa ExoProtein A (EPA) and adjuvanted with AS01. Our ongoing experience with Pfs25M-EPA and Pfs230D1M-EPA in Malian adult trial participants, and the extensive experience with the AS01 adjuvants in African children and adults, justify conducting the first-in-human trial of Pfs25M-EPA and Pfs230D1M-EPA with AS01 in Malian adults. This dose-escalating phase 1 study will determine safety, immunogenicity, and functional activity of these vaccines in Malian adults. Pfs25M-EPA + Pfs230D1M-EPA in AS01 will be assessed by mosquito feeding assays in Malian adults for evidence that they may reduce the number of malaria transmission events in study subjects.
A total of 305 subjects will be enrolled at multiple sites in Mali, West Africa to receive escalating doses of a malaria transmission blocking vaccine (s): Pfs25M-EPA/AS01, Pfs230D1M-EPA/AS01, or simultaneous administration of Pfs25M-EPA/AS01 and Pfs230D1M-EPA/AS01; or a comparator vaccine (ENERGIX-B). Enrollment within each group will be staggered for additional safety and subjects will only be enrolled into the co-administration group once each individual dose has been administered. Subjects will be followed for at least 6 months after the last vaccination. Safety outcomes will be local and systemic adverse events and serious adverse events. Immunogenicity outcomes will be antibody responses as measured by ELISA against recombinant Pfs25, Pfs230, EPA, CSP, and B cell and T cell responses. Functional activity of the induced antibodies will be assessed in TBV arms by standard membrane feeding assays conducted at the National Institute of Allergy and Infectious Diseases, and activity that interrupts malaria transmission will be measured in all arms by direct skin feeding assays in Mali.
Subjects in the open label safety cohorts (Arms 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b) will be offered reenrollment for follow-up laboratory assessment to explore the duration of immunogenicity and functional activity at approximately 9, 12 months post vaccination. Following scheduled, intentional unblinding, subjects enrolled in Arms 2c, 2d, and 4c will be provided the opportunity to re-enroll for a fourth vaccination (Arm 2c and 2d with 40 microgram dose of Pfs230D1M-EPA/AS01; Arm 4c with Menatctra) approximately 1 year post vaccination #3. Subjects in these arms will also be eligible to re-enroll for follow up of duration of immunogenicity and functional activity at approximately 9, 12 months post vaccination if they choose not to enroll to recive the booster vaccination. Subjects will be followed similarly to the previous year for safety, immunogenicity, and functional activity.

Participants received 3 doses of 40 μg Pfs230D1M-EPA/AS01 on Days 0, 28, then 8 μg Pfs230D1M-EPA/AS01 (100 µL TBV + AS01; fractional dose) on Day 168, then 4th dose of 40 μg Pfs230D1M-EPA/AS01 on Day 476 (Year 2) via intramuscular injections into the deltoid muscle (IM). Participants received antimalarial drug treatment with Coartem® approximately 1 week prior to first vaccination. Participants underwent antimalarial drug treatment with Coartem on D-7 (prior to vaccination #1); 4th vaccination on D476 Pfs230D1M-EPA: The Pfs230D1M-EPA was formulated as conjugated Pfs230D1M in 4 mM PBS to a 2X dilution of the high dose (160 μg/ml in 0.5 ml volume) in cGMP compliance at Walter Reed Bio-production facility in April 2016 and was provided as a single use vial. AS01: AS01B adjuvant was provided as a single use vial by GSK, 100 μg/mL MPL and 100 μg/mL QS21 in a liposomal formulation in a volume of 0.625 mL. One dose injected of AS01B corresponds to 50 μg QS21 and 50 μg MPL. Coartem: Artemether/lumefantrine (Coartem(R)) is a licensed antimalarial in the US and Mali for treatment of uncomplicated malaria. It has an excellent safety profile and is widely used to treat malaria. Subjects who may have had any contraindications to the use of these drugs were excluded at screening. Coartem was dosed with food and administered over 3 days for a total of 6 doses, as per package insert and standard adult dosing |
| OG002 | Safety Comparator & Efficacy Comparator Arm 4c: Dosing Interval 0, 28, 168, 476 Days | Participants received 3 doses of ENGERIX-B via on Days 0, 28, and 168, then 4th vaccination of Menactra® on Day 476 (Year 2) via intramuscular injections into the deltoid muscle (IM). Participants received antimalarial drug treatment with Coartem® approximately 1 week prior to first vaccination. Engerix-B: ENGERIX-B (hepatitis B vaccine; recombinant): is a sterile suspension of noninfectious hepatitis B virus surface antigen (HBsAg) for intramuscular administration. It contains purified HBsAg obtained by culturing genetically engineered Saccharomyces cerevisiae cells, which carry the surface antigen gene of the hepatitis B virus. Each 1-mL adult dose contains 20 g of HBsAg adsorbed on 0.5 mg aluminum as aluminum hydroxide. Menactra: Menactra is FDA approved for active immunization to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, Y, and W-135 (but does not protect against serotype B) for use in individuals 9 months through 55 years of age Coartem: Artemether/lumefantrine (Coartem®) is a licensed antimalarial in the US and Mali for treatment of uncomplicated malaria. It has an excellent safety profile and is widely used to treat malaria. Subjects who may have had any contraindications to the use of these drugs were excluded at screening. Coartem was dosed with food and administered over 3 days for a total of 6 doses, as per package insert and standard adult dosing |
