Filter by:In the Democratic Republic of Congo (DRC), malaria is an important cause of morbidity and mortality. It is estimated that malaria is responsible for 30% of admissions to hospital averaged throughout the country and for 25-30% mortality in children under five. In 2005, DRC adopted artesunate and amodiaquine (ASAQ) as first-line anti-malarial treatment. As WHO recommended that the efficacy of antimalarial drugs was monitored regularly to avoid an upsurge of mortality and morbidity due to continued use of ineffective drugs, a randomized, non-inferiority open-label trial was conducted in Katanga, in order to compare the efficacy of the fixed-dose formulation ASAQ versus artemether-lumefantrine (AL), Children aged six and 59 months with uncomplicated Plasmodium falciparum malaria were enrolledand randomly allocated into one of the two regimens. The risk of recurrent parasitaemia by day 42, both unadjusted and adjusted by PCR genotyping to distinguish recrudescence from new infection, was analysed. Between April 2008 and March 2009, 301 childrenwere included: 156 with ASAQ and 145 with AL. No early treatment failures were reported. Among the 256 patients followed-up at day 42, 32 patients developed late clinical or parasitological failure (9.9% (13/131) in the ASAQ group and 15.2% (19/125) in the AL group). After PCR correction, cure rates were 98.3% (95%CI, 94.1-99.8) in the ASAQ group and 99.1% (95%CI, 94.9-99.9) in the AL group (difference -0.7%, one sided 95%CI -3.1). Kaplan-Meier PCR-adjusted cure rates were similar. Both treatment regimens were generally well tolerated. Both ASAQ and AL are highly effective and currently adequate as the first-line treatment of uncomplicated falciparum malaria in this area of Katanga, DRC. However, in a very large country such as DRC, and because of possible emergence of resistance from other endemic regions, surveillance of efficacy of artemisinin-based combination treatments, including other evaluations of the resistance of ASAQ, need to be done in other provinces.
The purpose of this study is to see if two new malaria vaccines called FMP1 and RTSS, combined with an adjuvant (called SBAS2) which helps stimulate the body's immune system, are safe, demonstrate an immune response through blood tests, and lastly, to see if the vaccines can prevent malaria infection. The RTS,S vaccine contains a malaria protein in combination with a portion of the commercially available hepatitis B vaccine. The FMP1 vaccine also contains a malaria protein. The adjuvant called SBAS2, is a special oil in water emulsion. Vaccinations are done at study days 0, 28 and 84, followed by a malaria challenge approximately 14 days after the 3rd vaccination.
Malaria has remained a major concern for the US military. During World War II, malaria was the leading cause of disease and non-battle injury with 500-700 men infected per day, resulting in 24,000 malaria-related casualties.(10) Currently, the methods used for protecting troops against malaria are insecticidal nets, clothing, and antimalarial treatment. To be effective, these methods must be self-administered and be used consistently, often unattainable in field or combat situations. The United States Army Medical Research and Development Command (USAMRMC), through the United States Army Medical Materiel Development Activity (USAMMDA) and the Walter Reed Army Institute of Research (WRAIR) are actively pursuing the development of an effective vaccine against P. falciparum malaria; development of such a vaccine is a high priority for the US military and other individuals who travel to endemic regions, and is equally important to populations residing in those areas. A Phase 1 study using FMP012, a recombinant E.coli expressed malaria protein (CelTOS) vaccine will 1. assess the safety and reactogenicity of candidate P. falciparum malaria vaccine FMP012/GLA-SE Secondary: 2. measure the humoral immune response to FMP012/GLA-SE using enzyme-linked immunosorbent assay (ELISA) 3. assess the protective efficacy of FMP012/GLA-SE against a P. falciparum sporozoite challenge.
This is an open label uncontrolled study to determine the efficacy of fosmidomycin and clindamycin when co-administered orally over three days in the treatment of acute uncomplicated Plasmodium falciparum malaria in children. The primary study endpoints will be the cure rate on Day 28 (PCR corrected). The secondary endpoints will be the cure rate on Day 7 and the parasite and fever clearance times.
The aim of this study is to evaluate the role of azithromycin as a possible combination partner for fosmidomycin to protect it from its susceptibility to recrudescent infections when used as monotherapy for acute Plasmodium falciparum malaria while retaining its excellent safety profile.
The purpose of this study is to determine the tolerability and pharmacokinetics of Sevuparin/DF02 when administered as an i.v. infusion in combination with Malanil® (atovaquone/proguanil) as anti-malarial treatment in subjects affected with uncomplicated malaria. The study will also assess the potential of Sevupatin/DF02 to reduce infected erythrocyte sequestration and rosette formation. The study consists of a dose escalation part (part 1) followed by an open labelled, randomized comparison of treatment with Sevuparin/DF02 and Malanil® versus Malanil® alone (part 2).
Title: Efficacy and safety of artesunate-amodiaquine combined with methylene blue for falciparum malaria treatment in African children: randomised controlled trial. Design: Mono-centre, two arms, open randomized controlled study in children with uncomplicated falciparum malaria in Burkina Faso. Phase: Phase II. Objectives: The primary objective of this trial is to study the efficacy and safety of the triple therapy artesunate (AS) - amodiaquine (AQ) - methylene blue (MB) given over three days in young children with uncomplicated falciparum malaria in Burkina Faso compared to the local standard three days artemisinin-based combination therapy (ACT) AS-AQ regimen. Population: Children aged 6-59 months with uncomplicated falciparum malaria from Nouna Hospital in north-western Burkina Faso. Sample size: 180 patients (90 per study arm).
A randomized controlled trial to assess the safety and efficacy of azithromycin combination therapy for use in severe malaria. This pilot trial will be conducted in uncomplicated malaria patients in southeastern Bangladesh.
The purpose of this study is to evaluate the safety and efficacy of lower doses of primaquine compared to the dose recommended by the WHO for reducing P. falciparum gametocytes in the infected human host to prevent transmission of falciparum malaria to the anopheles mosquito vector.
Few efficient drugs for malaria treatment are available so far. Due to increased exposure of these drugs and due to the high risk of development of drug resistant strains of Plasmodium falciparum, new drug combinations have to be actively investigated. The investigators will test the efficiency, safety and tolerance of combined fosmidomycin and clindamycin treatment in acute uncomplicated malaria in children aged 3-10 years.
