Official title
Phase 1 Study of the Safety of Immunization of Naive Individuals With AMA1-C1/Alhydrogel [R], an Asexual Blood-Stage Vaccine for Plasmodium Falciparum Malaria, and the Effect of Immunization on Antigen-specific Memory and Plasma B Cells and T Cells
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine the safety and immune response of healthy adult volunteers to AMA1-C1, an experimental malaria vaccine developed by the NIAID. Malaria affects about 300 million to 500 million people worldwide each year, causing from 2 million to 3 million deaths. Increasing drug resistance to the malaria parasite, as well as widespread resistance of mosquitoes (the insects that transmit the parasite) to pesticides are reducing the ability to control malaria through these strategies. A vaccine that could reduce illness and death from malaria would be a valuable new resource in the fight against this disease. Early tests of AMA1-C1 in 66 people in the United States and in Mali, West Africa, found no serious side effects of the vaccine. This study will test a shorter schedule of vaccinations with AMA1-C1 than that used in the previous studies. Healthy volunteers between 18 and 50 years of age who weigh at least 110 pounds and with no travel to malaria endemic areas in the past 12 months may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, and a urine pregnancy test for women who are able to bear children. Participants are randomly assigned to receive three injections of either the experimental malaria vaccine or a placebo (a solution that does not contain the vaccine) over a 2-month period. The shots are given in an upper arm muscle, each 1 month apart. On the day of each injection, participants give a history of symptoms since the last visit, have a brief physical examination and blood test and, for women, a blood or urine pregnancy test. After the injection, participants remain in the clinic 60 minutes for observation. In addition to the injections, participants undergo the following procedures: * Record temperature and symptoms on a diary card daily for the first 7 days after each injection. * Follow-up clinic visits 1, 3, 7 and 14 days after each shot to check for side effects. Blood samples are drawn before each injection and at each return clinic visit to check the safety and immune response to the vaccine. * Have apheresis, a special procedure that separates certain components of the blood, 7 days after each injection to measure the function of germ-fighting blood cells. For this procedure, blood is drawn through a needle in an arm vein and directed into a machine that separates the different types of blood cells. The white cells are collected in a plastic ...
