Filter by:Background: Malaria remains a major global health problem. Malaria is spread by the bite of mosquitos. Africa is the region of the world where most people get malaria. Sanaria PfSPZ Challenge is a malaria vaccine. Researchers want to see if the vaccine combined with partner drugs can help protect against malaria. Objective: To test if injections with 3 monthly doses of Sanaria PfSPZ Challenge, combined with either pyrimethamine (PYR) or chloroquine as a partner drug, is safe, tolerable, and effective. Eligibility: Healthy people ages 18-50 years who live in Bancoumana, Mali, or nearby Design: Participants will be screened with the Malaria Comprehension Exam to check their understanding of the study. They will have a medical history. They will have a physical exam. They will have blood tests, urine tests, and heart tests. Participants will join either the pilot study or the main study. Participants will be assigned to groups. Depending on their group, they will get at least one injection of either a placebo or the vaccine. They may have up to 3 vaccines, 4 weeks apart. The injection will be into a vein with a needle. Participants will also take pyrimethamine or chloroquine by mouth. They will also take standard doses of antimalarial drugs by mouth. Participants will have blood tests throughout the study. Participants may develop a rash or injection site reaction. If this happens, photos of the site may be taken. Participants will be observed for infection for many days after the injections.
This is a phase IIb clinical trial in malaria-exposed individuals to assess the immunogenicity, safety and efficacy of the two vaccines in the context of controlled human malaria infection, P. falciparum sporozoite challenge (PfSPZ Challenge).
AZITHROMYCIN VERSUS SULPHADOXINE‑PYRIMETHAMINE FOR PROPHYLAXIS AGAINST MALARIA IN PREGNANCY IN OWO, SOUIHWESTERN NIGERIA: A RANDOMISED CONTROLLED TRIAL OBJECTIVE: This study is to compare the efficacy of Azithromycin versus sulphadoxine‑pyrimethamine as options of chemoprophylaxis against malaria in pregnancy. METHOD: This is a randomized controlled trial with parallel assignment that will be conducted in the Obstetrics and Gynaecology department of the Federal Medical Centre. One hundred and sixty four (164) pregnant women who are eligible will be randomly allocated to 2 groups (A and B) of 84 each, using computer generated random numbers. Group A will receive sulfadoxine-pyrimethamine for malaria prophylaxis while Group B will receive azithromycin. All other aspects of antenatal care till delivery will be the same for all the women recruited. Maternal venous blood samples for malaria parasitaemia will be collected on recruitment and repeated at follow-up visits at any gestation there are symptoms of malaria; maternal peripheral blood film, placental and cord blood samples will be collected at delivery. All data will be documented in the data collection sheet. The results obtained will be subjected to statistical analysis using statistical package for social sciences (SPSS) version 21, Armonk, NY:IBM. The level of significance will be set at 5%. Outcomes will be compared across groups using Chi-square.
A partially blinded randomised controlled non-inferiority trial comparing the efficacy, tolerability and safety of Triple ACTs artemether-lumefantrine + amodiaquine (AL+AQ) and artesunate- mefloquine+piperaquine (AS-MQ+PPQ) with the ACTs artemether-lumefantrine + placebo (AL+PBO) and artesunate- mefloquine + placebo (AS-MQ+PBO) (with single-low dose primaquine in some sites) for the treatment of uncomplicated Plasmodium falciparum malaria to assess and compare their efficacy, safety, tolerability.
Background: Blood disorders like sickle cell disease and malaria affect many people around the world. Researchers want to learn more about blood disorders. To do this, they need to collect biological samples from people with blood disorders. They also need to collect samples from healthy people. Objective: To collect samples to use for research on blood disorders. Eligibility: People ages 18-70 who have blood disorders. Healthy volunteers without blood disorders are also needed. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will give one or more samples. They will give them over 5 years. They can choose not to give any of the samples: Saliva: Participants will spit into a tube. They may also have the inside of their mouth swabbed. Urine: Participants will urinate into a cup. Blood: Blood will be taken through a needle in the participant s arm. Fat samples: An area on the participant s belly or buttock will be numbed. A small cut will be made into the skin and a small piece of fat removed. Mucus and cells from the lungs: The participant will be sedated. A flexible tube will be inserted through the nose or mouth into the lung airways. These participants will also have a physical exam, chest x-ray, and heart tests after the procedure. ...
To investigate the comparative tolerability, metabolism and pharmacokinetics of individual enantiomers of PQ in healthy human volunteers, receiving study drug over the course of 7 days.
The massive scale-up of Long Lasting Insecticidal Nets (LLIN) has led to a major reduction in malaria burden (up to 50%) in many sub-Saharan African countries. This progress is threatened by the wide scale selection of insecticide resistant malaria vectors. New types of LLIN combining a mixture of two insecticides have been developed to control resistant mosquitoes. The efficacy of two bi-treated LLIN are compared to a standard LLIN in a three-arm, single blinded, cluster-randomized trial in Cove, Benin. The arms are; 1/ Royal Guard, a net combining pyriproxyfen (PPF), which is known to disrupt female reproduction and fertility of eggs, and the pyrethroid alpha-cypermethrin, 2/Interceptor G2, LLIN incorporating a mixture of two adulticides with different modes of action; chlorfenapyr and a pyrethroid (alpha-cypermethrin), and 3/ The control arm: Interceptor, a standard LLIN treated with alpha-cypermethrin. The primary outcome of the trial will be malaria case incidence in children aged 6 months to 10 years.
A partially blinded randomised controlled non-inferiority trial comparing the efficacy, tolerability and safety of Triple ACTs artemether-lumefantrine+amodiaquine (AL+AQ) and artesunate-mefloquine+piperaquine (ASMQ+PPQ) and the ACTs artemether-lumefantrine+placebo (AL+PBO), artesunate-mefloquine+placebo (ASMQ+PBO) (with single-low dose primaquine in some sites) for the treatment of uncomplicated Plasmodium falciparum malaria to assess and compare their efficacy, safety, tolerability.
Background: Malaria affects many people in Mali and other parts of Africa. It is spread by mosquito bites. Malaria can make people sick or can lead to death. Scientists want to learn if a vaccine can stop it from spreading to other people. Objective: To test how well an experimental malaria vaccine works to decrease malaria infections. Eligibility: Healthy people ages 5 and older who live in Doneguebougou, Mali, and surrounding areas Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests EKG Participants will be randomly assigned to get either the experimental vaccine or an approved vaccine. They will not know which they are getting. Participants will have a visit about a week before their first vaccine. They will take a medicine that kills malaria. They will take it at the clinic the next 2 days. Participants ages 5-8 will take the drug again 2 weeks before their third vaccine. Participants get the vaccine through a needle in the arm. They will have visits 1, 3, 7, and 14 days after. They will have blood tests or finger pricks. Participants will get another vaccine 1 and 6 months later. Participants will have blood tests once a month. At these visits they may also have urines tests or mosquito feeds. For the feeds a cup full of mosquitoes will be placed on arms or legs for 15-20 minutes. Participants will have visits twice a month for 4 months after their last vaccine.
This study is designed as a multi-centre randomized, open label trial to compare the safety and efficacy of a high dose primaquine (PQ) treatment in G6PD normal patients with P. falciparum to reduce the risk of subsequent P. vivax episodes to current standard practice of providing only schizontocidal treatment.
