Active clinical trials for "Malaria"

The study aims to show that the candidate malaria vaccine GMZ2 is as safe as the already publicly used vaccine against rabies. 40 adult male Gabonese volunteers will be enrolled and randomly allocated to receive either malaria vaccine or rabies vaccine without the investigator or the participants knowing what they received. They will receive 3 doses each at one month intervals, and will be followed up for one year to evaluate safety parameters. This is the first time this product will be tested in Africa

This study will be the first time that the candidate malaria vaccine Apical Membrane Antigen 1 (PfAMA-1-FVO[25-545]) will be tested in malaria endemic populations. The phase Ib study will include adults who will be randomly allocated to either receive the malaria vaccine or the vaccine against Tetanus. Each participant will receive 3 immunizations, without the clinical investigators or the participants themselves knowing what has been given. They will then be follow-up up for immediate reactions to vaccination, and also over a longer term of one year. Blood will be taken to evaluate the biological safety parameters and also immune responses.

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.

HIV and malaria are two of the most important diseases to afflict children in sub-Saharan Africa. However, it is unknown what relationships exist between the two diseases. The purpose of this study is to determine the relationship between HIV and malaria infections in HIV infected Ugandan children.

This study will examine whether resistance to severe malaria is associated with weakening of a specific immune response (TLR-mediated pro-inflammatory cytokine response). Some children with mild malaria go on to develop severe disease, while others do not. The study will analyze certain substances in the blood to try to determine what factors may protect against severe malaria. Healthy children and children 3 - 10 years of age with severe malaria who are being treated at l'H pital Gabriel Toure in Mamako, Mali, West Africa, may be eligible for this study. Participants have a mall sample of blood drawn from a vein and from two finger pricks.

We aim to evaluate whether IPT in pregnancy provides any additional benefit to the protection afforded by ITNs.

Malaria is a sickness passed from one person to the other by the bite of a mosquito. In areas of frequent malaria infection, children may develop natural protection against malaria and they are less likely to become sick or die from it as they age. The purpose of this study is to investigate the body's natural protection against malaria in children by testing their blood. This information may help investigators develop a malaria vaccine. The Navrongo Health Research Centre is conducting this study in Ghana. Three hundred healthy children between the ages of 1 and 5 years will participate in the study for 12 months. Study procedures will include 7 field worker visits to check on the child's health and obtain a blood sample. Every two months, a blood sample will be taken from each child to test it for strength against malaria. Whenever a child is sick, the child will be tested for malaria.

This project aims to disentangle the role of host immune resistance and disease tolerance in afebrile malaria infections, with the goal of guiding context-adapted tactics to target this hidden reservoir, as well as to develop new approaches to clear malaria infection and reduce its severity through host-directed therapies.

The main aim of this study is to determine the effect of awareness campaigns by school children targeting their communities on knowledge, attitudes, and practices in malaria control in the Mbandjock health district. A two-arm, open-label, randomized controlled clinical trial will be adopted with the Mbandjock Health District as the test district and Sa'a Health District as control Health District. This will last from January 2017 to December 2020. The Lot Quality Assurance Sampling (LQAS) method was used. The health area was selected in the ratio 2:1. A total of 209 pupils and 209 adults shall be enrolled from households located in Mbandjock. Similarly, 114 pupils and 114 adults will be recruited in Sa'a. In addition, 57 teachers shall be enrolled in the District of Mbandjock only. A total of 703 participants shall be enrolled during the study.

This stepped-wedge cluster-randomized controlled trial with nested mixed methods study will assess the effectiveness, acceptability, feasibility and cost effectiveness of a personal protection package to reduce malaria transmission among mobile and migrant populations (MMPs) and the general population in their residing villages in Myanmar.
