NCT ID: NCT00669084 Completed - Malaria Clinical Trials

Innate and Acquired Resistance to Plasmodium Falciparum Malaria in Mali

Start date: April 21, 2008
Phase:
Study type: Observational

This study, sponsored by NIAID and the University of Bamako, Mali, will identify genetic and other factors that may protect against severe malaria in some children. Children between 6 months and 17 years of age who live in Kenieroba, Fourda or Bozokin villages in Mali may enroll in the study. Participants have a blood sample collected by finger prick with a small needle. The blood is examined for gene variants that influence the severity of disease in children exposed to the malaria parasite. Children who develop a fever or other symptoms of malaria are evaluated and treated in Kenieroba s health center for up to 5 years from entering the study, or until they reach 18 years of age. The children are treated with artesunate and amodiaquine. Children with severe disease are treated with quinine. One tablespoon of blood is drawn from the children for study. At the end of the dry season and the wet season, a subset of 200 healthy children are asked to provide 1 or 2 tablespoons of blood, drawn through a needle placed in a vein in the arm. Additional research blood samples may be requested from children between 2 and 17 years old. Blood will not be taken from any child more than twice a year. ...

NCT ID: NCT00623155 Completed - Malaria Clinical Trials

Seasonal Intermittent Preventive Treatment With Sulfadoxine-Pyrimethamine in Children in Mali

Start date: July 2002
Phase: N/A
Study type: Interventional

Recent, randomized controlled trials conducted in areas of perennial malaria transmission have shown that intermittent preventive treatment (IPT) given at the time of vaccination reduced the incidence of the first episode of malaria and severe anaemia during the first year of life by more than 50% without there being any rebound in the subsequent year. However, in countries such as Mali, where malaria is highly seasonal and prevalent in older children, IPT in infants may not be the optimum way in which to use antimalarial drugs to prevent malaria. An alternative approach is to give intermittent preventive treatment to children at risk just during the rainy season. Here we propose (i) to evaluate the impact of two seasonal IPT (sIPT) with Sulfadoxine-pyrimethamine (SP) given at 8 weeks interval on the incidence of malaria disease in children of 6 months to 10 years in an area of seasonal transmission, in Kambila, Mali; (ii) to assess the impact of this strategy on the in vivo response of P. falciparum to SP; (iii) to assess the potential rebound effect of this strategy on the subsequent transmission season after the cessation. Children 6 months-10 years in Kambila, Mali will randomized to receive either IPT with SP twice at 8 weeks interval or no IPT during the transmission season and will followed up for 12 months. Subjects will be also followed during the subsequent transmission season to assess possible rebound effect. Clinical malaria cases will be treated with SP and followed for 28 days to assess the in vivo response during both periods.

NCT ID: NCT00541385 Completed - Malaria Clinical Trials

Pyronaridine Artesunate 3:1 Granule Formulation vs. Coartem© Crushed Tablets in P. Falciparum Malaria Pediatric Patients

Start date: October 2007
Phase: Phase 3
Study type: Interventional

The primary objective of this Phase III clinical study is to demonstrate the efficacy of the fixed combination of pyronaridine artesunate (PA) granule formulation (60:20 mg; pediatric PYRAMAX®) by showing a PCR-corrected adequate clinical and parasitological cure rate (ACPR) of more than 90%. Secondary objectives of this clinical study are to compare the efficacy (non-inferiority) and safety of the PA granule formulation compared to Coartem® (ie, the combination of artemether/lumefantrine [AL]) crushed tablets in a paediatric population and to assess the safety of the PA granule formulation.

NCT ID: NCT00527163 Completed - Malaria Clinical Trials

Role of Nitric Oxide in Malaria

Start date: September 4, 2007
Phase:
Study type: Observational

This study, conducted by NIH, the University of Bamako in Mali, Africa, and Tulane University will examine the relationships between hemolysis (breakdown of red blood cells), nitric oxide (a gas important in regulating blood vessel dilation and blood flow) and pulmonary hypertension in patients with malaria. Malaria is among the leading causes of death in many of the world s poorest countries. It is caused by a parasite that is transmitted to humans by mosquitoes. Malian children ages 1-5 years are eligible for participation in this study. They include children with asymptomatic infection, uncomplicated disease, and severe disease. Uninfected controls are also included. Upon enrollment, participants have a medical history and physical examination, echocardiogram (ultrasound test of heart function) and blood tests. In addition, all participants (infected children and controls) have repeat evaluations when healthy, approximately 7 to10 days following successful therapy.

NCT ID: NCT00510159 Completed - Clinical trials for Schistosoma Haematobium

Comparing Praziquantel Versus Artesunate + Sulfamethoxypyrazine/Pyrimethamine for Treating Schistosomiasis

Start date: August 2007
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study is to evaluate the efficacy of praziquantel versus As+SMP (Co-Arinate FDC ®) in the treatment of Schistosoma haematobium in 6-15 year old Malian children. The nul-hypothesis in this study is that the combination of As+SMP is more effective than praziquantel in the treatment of S. haematobium infected children.

NCT ID: NCT00484900 Completed - Clinical trials for Plasmodium Falciparum Malaria

Multi-Centre Trial Comparing Three Artemisinin-Based Combination Treatments on P. Falciparum Malaria

Start date: May 2006
Phase: Phase 3
Study type: Interventional

The purpose of this open randomised multi-centre clinical trial is to test the hypothesis that three pills of the fixed dose combination artesunate/sulfamethoxypyrazine/pyrimethamine, administered over 24 hours is not inferior in efficacy to the same drug administered over 48 hours and that the fixed dose combination artesunate/sulfamethoxypyrazine/pyrimethamine As/SMP fdc, independently of the duration of its dose interval, is not inferior in efficacy to 6 - 24 pills (number of pills administered to respectively children and adults)of the 60 hours treatment of artemether/lumefantrine for the treatment of uncomplicated P. falciparum malaria.

NCT ID: NCT00471666 Completed - Malaria Clinical Trials

Medical Implications of Coinfection With Malaria and Filariasis Parasites

Start date: May 7, 2007
Phase: N/A
Study type: Observational

This study will examine the clinical, immunological and epidemiological effects of concurrent infections with P. falciparum and W. bancrofti or M. perstans (the parasites that cause malaria and filariasis) on the frequency and severity of malaria infection in children and young adults in Mali, Africa. Residents of Tien gu bougou and Bougoudiana, Mali, who are between 1 and 20 years of age may be eligible for this study. Participants with and without filarial infection will be enrolled. Participants undergo the following tests and procedures: - Baseline evaluation with medical history and physical examination, blood tests and stool culture - Brief physical examinations weekly - Blood tests monthly for malaria - Standard treatment offered for anyone with malaria - Blood tests for filarial infection at the beginning, midpoint and end of the transmission season - Treatment for lymphatic filariasis is available through the National Program for the Elimination of Lymphatic Filariasis. There is no effective standard therapy for M. perstans. - Treatment for other parasitic worm infections, if needed.

NCT ID: NCT00471302 Completed - Malaria Clinical Trials

Normal Immunological Parameters Among Healthy Volunteers in Kambila, Mali

Start date: August 1, 2007
Phase:
Study type: Observational

This study will determine the immune response to malaria infection in healthy volunteers compared with malaria patients. Malaria affects millions of people in Mali and Africa. It can cause fever, headaches, body aches, and weakness. Without treatment, the disease can be very serious in children. Developing an effective vaccine against the parasite that causes malaria is a crucial step toward controlling the disease; however, vaccines tested so far have provided very short-lived protection. A better understanding of the natural immunity to malaria may provide insight that can be applied to developing a more effective vaccine. People 18 years of age or older who live in Kambila, Tieneguebougou or Kalifabougou, Mali, and are in good health may be eligible for this study. Participants undergo a complete physical examination at the start of the study and then once a year for the 4-year duration of the study. They have a maximum of nine clinic visits a year to collect blood samples for research. The visits last about one hour, including a 30-minute observation time after the blood draw.

NCT ID: NCT00460525 Completed - Clinical trials for Plasmodium Falciparum Malaria

Phase II AMA-1 Malaria Vaccine FMP2.1/AS02A Trial in Mali

Start date: May 2007
Phase: Phase 2
Study type: Interventional

Malaria is a disease that affects many people in Africa. Malaria is caused by germs spread by mosquito bites. The purpose of this study is to compare the number of children who get malaria after receiving an experimental malaria vaccine (FMP2.1/AS02A) to the number of children who get malaria after receiving a vaccine for rabies (an approved vaccine that does not prevent malaria). The children will be assigned to one of the vaccine groups by chance. Participants and doctors will not know which vaccine was given. Study participants will include 400 children, ages 1-6 years, living in Bandiagara, Mali. Children will receive 3 vaccine doses, by injection, to their upper arm. Study procedures will include physical exams and several blood samples. Participants will be involved in the study for 26 months.
