Design: Single-centre Indication: Malaria caused by Plasmodium falciparum Objectives: To determine and compare the efficacy of AQ treatment in young children with uncomplicated falciparum malaria in the rural and the urban study area of the Centre de Recherche en Santé de Nouna (CRSN). Population: Children aged 6-59 months with uncomplicated falciparum malaria (axillary temperature ≥ 37.5°C + ≥ 2.000 P. falciparum asexual parasites per µl blood) from the health centre situated in the villages of Bagala, Bourasso and Kemena and from Nouna town hospital outpatient department. Sample size: N=120 Treatment: All children will receive a total dose of 25 mg/kg oral AQ over a period of three days (first and second day: 10mg/kg, third day: 5mg/kg). Statistical procedures: The primary analysis parameter is the proportion of clinical failures on day 14. Secondary parameters are the rate of clinical failures on day 28 (with and without PCR correction), the rate of early clinical failures, the rate of late parasitological failures (day 14 and day 28), and the rate of adverse events. Data will be analysed in the overall group of study children and for rural (n=50) and urban (n=50) study children separately. Study duration and dates: The study will be implemented in September-December 2005.
Treatment of Plasmodium falciparum malaria in Africa is increasingly difficult. Resistance to cheap efficient antimalarial drugs poses an increasing threat. The rapid emergence of resistance to sulfadoxine - pyrimethamine, already seen in East Africa is growing and is likely to have an striking impact on mortality in many other African regions where no obvious alternatives are available. WHO recommends the use of drug combinations containing artemisinin compounds, i.e., artemisinin-based combination therapies (ACT). Previous clinical trials have shown that the combination of artesunate with mefloquine is highly effective and well tolerated in the treatment of multidrug-resistant falciparum malaria, retaining the benefit of rapidity of action while augmenting cure rates, and apparently slowing the development of mefloquine resistance. Compliance with sequential combination regimen of antimalarial drugs is notoriously poor. Therefore, in order to limit the development of resistance to both drugs and ameliorate patients' compliance to antimalarial treatments, an optimal simultaneous combination regimen of artesunate and mefloquine in a practical single blister pack has been developed by Mepha Ltd. and successfully tested. The currently available
This study will assess the safety and efficacy of co-artemether in the treatment of acute uncomplicated P. falciparum malaria in returning non-immune travellers THIS STUDY IS NOT ENROLLING PATIENTS IN THE UNITED STATES
The purpose of this study is to determine whether artemether + lumefantrine is as effective as chloroquine + sulfadoxine pyrimethamine in the treatment of uncomplicated Plasmodium falciparum malaria
This trial is currently evaluating one candidate malaria vaccine, FMP1/AS02A. This candidate malaria vaccine is being developed for the routine immunization of infants and children living in malaria-endemic areas. This vaccine would offer protection against malaria disease due to the parasite Plasmodium falciparum. Prior to the start of this study, FMP1/AS02A had been given to approximately 60 malaria-naïve adults and 40 adults and 90 children living in malaria-endemic regions. This study will investigate whether the candidate vaccine prevents malaria disease for 6 months post-vaccination. One half of the enrolled subjects will receive FMP1/AS02A and the other half rabies vaccine (RabAvert).
Sulfadoxine-pyrimethamine (SP) is the current first-line treatment for uncomplicated malaria in Malawi. The malaria parasite P. falciparum has developed resistance to this drug so that the drug is much less effective than in previous years. This study was developed and conducted in collaboration with the National Malaria Control Programme of Malawi to assess the efficacy of four antimalarial drug combinations to provide evidence to assist the Malawian Ministry of Health in identifying and implementing as policy the next first-line antimalarial for uncomplicated malaria in Malawi. In an open, randomized trial in children under five years of age, four drug combinations, all of which are licensed in Malawi, are being assessed: amodiaquine plus sulfadoxine-pyrimethamine (AQ-SP), amodiaquine plus artesunate (AQ-Art), chlorproguanil-dapsone plus artesunate (CD-Art) and lumefantrine-artemether (LA). SP is also included as a fifth arm of the study for current data on its efficacy. Data on side effects of the drugs will also be collected. The results of this study will provide some of the information necessary to guide the Malawi National Malaria Control Program in selecting its next first antimalarial treatment for uncomplicated malaria. The study adheres to the World Health Organization's 2003 standardized protocol for assessing antimalarial drug efficacy.
Sulfadoxine-pyrimethamine is the current first-line therapy for uncomplicated malaria in Malawi. Significant resistance of the P. falciparum malaria parasite to this drug has led to an imminent need for the government of Malawi to identify a new first-line therapy for uncomplicated malaria and to implement that new therapy as policy. This protocol is the second of two protocols whose combined purpose is to provide efficacy and side effect data on four antimalarial drug combinations that are candidates for the next first-line therapy for uncomplicated malaria in Malawi. This protocol aims to assess the acceptability and tolerability of amodiaquine in Malawi. It is a double-blind study comparing amodiaquine plus artesunate (AQ-Art, one of the candidate combination therapies) to chlorproguanil/dapsone plus artesunate (CD-Art, another of the candidate combination therapies) in persons 5 years and older, to see if there is a higher incidence of abdominal pain and/or refusal to take the therapy in the AQ-Art group. Amodiaquine was removed from the Malawian national drug registry in 1995 because of a perceived association with abdominal pain. Although no studies were conducted to substantiate this, consensus among clinicians was that patients were refusing amodiaquine with increasing frequency, citing abdominal pain as the reason, so the drug was removed from the registry. Results from this study, along with the efficacy data from the sister protocol in children under five years of age, will help guide the National Malaria Control Program of Malawi in selecting their next first-line antimalarial therapy.
This is a study of the efficacy and effectiveness of combination therapy for malaria due to P. falciparum in the Loreto Department, Iquitos, Peru. The investigators will enroll subjects ≥ 1 year-old who have a diagnosis of uncomplicated malaria due to P. falciparum. Patients will receive a treatment regimen consisting of mefloquine (25 mg/kg per day for two days) and artesunate (12 mg/kg per day for three days). Patients will be divided into two groups: one will receive drugs under direct supervision and the other will be instructed on how to take the drugs by themselves. Clinical and parasitologic response will be monitored for a follow-up period of 28 days. The findings of this study will be used to guide the Ministry of Health in evaluating its national policy for P. falciparum malaria treatment.
Chloroquine resistant falciparum malaria in Pakistan is prevalent in every malarious area examined. Resistance to the favoured second-line treatment, sulphadoxine-pyrimethamine S/P is rising fast. To avert a repetition of the resistance catastrophe that occurred in SE Asia it is critical to preserve the effective life of SP by using it in combination with artesunate. Efficacy of ACT with artesunate in combination with chloroquine, SP or amodiaquine for treatment of malaria (falciparum or vivax) will be examined in malaria patients in Pakistan.
