Filter by:This is a clinical study to assess the safety of primary, secondary and tertiary blood-stage controlled human Plasmodium falciparum malaria infection of healthy malaria-naïve UK adults, as well as to evaluate any effect of prior exposure to a blood-stage controlled human malaria infection (CHMI) on the parasite multiplication rate. As a secondary objective, the immune response to primary, secondary and tertiary P. falciparum blood-stage infection, as well as gametocytaemia, will also be assessed.
Daily iron (ferrous sulfate, 2 mg/kg/day) or placebo syrup for first four months (112 days) of the 12-month (336-day) study. Children in the immediate iron group will receive iron syrup for the first three months (84 days) and placebo syrup for the fourth month. Children in the delayed iron group will receive placebo syrup for the first month (28 days) and iron syrup for the second, third, and fourth months.
This is a double blind randomised controlled clinical trial to evaluate the efficacy of R21 adjuvanted with Matrix-M in healthy 5-17 month old children in a malaria endemic area.
Objectives: Primary: • To characterize the infectivity of the new lot of Plasmodium falciparum strain 3D7 within the standard WRAIR CHMI model as compared to the current lot (historical data) Secondary: - To assess safety of the new lot of P falciparum parasites - To assess the kinetics of detecting parasitemia and parasite clearance by quantitative polymerase chain reaction (qPCR) as compared to blood smear - To obtain plasma samples to restore the testing control pool for malaria serology testing and for future malaria research
Under the World Health Organization's (WHO) integrated community case management (iCCM) Rapid Access Expansion Program (RAcE), World Vision Niger and Canada supported the Niger Ministry of Public Health to implement iCCM in four health districts in Niger in 2013. Community health workers (CHWs), known as Relais Communautaire (RCom), were deployed in their communities to diagnose and treat children under five years of age presenting with diarrhea, malaria and pneumonia and refer children with severe illness to the higher-level facilities. Two of the districts piloted RCom using smartphones equipped with an application to support quality case management and provide good timely clinical data. A two-arm cluster randomized trial assessed the impact of use of the mHealth application mainly on quality of care (QoC), but also on motivation, retention and supervision
This study is a proof-of-concept, first in human, Phase I, single center study designed to evaluate the safety, tolerability, immunogenicity and experimental efficacy of VLPM01 in healthy, malaria-naïve adult volunteers. The VLPM01 product will be adjuvanted with alhydrogel. The study design was based on the FDA's guidance "General Principles for the Development of Vaccines to protect Against Global Infectious Diseases" (2011).
The RTS, S/AS01E vaccine has been developed for routine immunization of children living in malaria- endemic countries of sub-Saharan Africa. This study is intended as a post-implementation safety study (after vaccine implementation), with the primary objective to evaluate the safety of vaccine after its administration. In addition to the primary objective, the study will also evaluate the impact and effectiveness of the vaccine.
MALARIA-092 (NCT03162614) study was designed to evaluate the efficacy, immunogenicity and safety of various dose schedules and formulations of GSK Biologicals' candidate malaria vaccine (RTS,S/AS01E) in healthy malaria-naïve subjects aged 18-55 years. The purpose of this study (follow-up to MALARIA-092 [NCT03162614] study) is to evaluate if protection can be extended with an additional Fx booster dose and if unprotected subjects can be protected following a Fx booster dose. In this booster study, subjects from MALARIA-092 (NCT03162614) study who completed vaccination and challenge will receive a Fx booster dose of RTS,S/AS01E and undergo a second controlled human malaria infection (CHMI) three to four weeks after vaccination. Additionally, subjects will be newly enrolled and will only undergo the sporozoite challenge as infectivity controls.
This study will assess the efficacy of Pyramax administered for three-day, two-day or one day, in clearing a P. falciparum infection in asymptomatic carriers. .
This is an open label, randomized, controlled clinical trial. The primary aim of this project is to determine the safety and tolerability of NF135.C10 sporozoite immunization under chemoprophylaxis against homologous and heterologous challenge infection.
