CDA is a combination of chlorproguanil, dapsone and artesunate, being developed in a public-private partnership with the Medicines for Malaria Venture (MMV), World Health Organisation (WHO-TDR) and academic partners from the London School of Hygiene and Tropical Medicine, University of Liverpool and the Liverpool School of Tropical Medicine as a treatment for acute uncomplicated P. falciparum malaria.
The combination of chlorproguanil HCl (CPG) and dapsone (DDS) as chlorproguanil-dapsone has already been shown to be efficacious against P.falciparum in adults and children in Sub-Sahara Africa. The addition of artesunate to LAPDAP has been demonstrated to increase the parasite kill rate as demonstrated in the phase II study, and reduce the chance of any parasites escaping treatment over the 3-day course. The addition of artesunate is also anticipated to have the population benefit of protection against the development of resistant strains of P.falciparum, although it will not be possible to demonstrate this in a clinical trial. One further population benefit of the artemisinin drugs are their ability to suppress the sexual forms of the parasite (gametocytes), which should reduce infectivity after antimalarial treatment and potentially lower transmission rates with widespread use, including the spread of any parasites resistant to the partner drug.
The aims of this phase III study are to compare the efficacy of a fixed ratio combination tablet of CDA to chlorproguanil-dapsone, and collect supporting safety data. This will be a multi-centre, double-blind, double-dummy, randomised trial, in children, adolescents and adults, with chlorproguanil-dapsone as a comparator.

To determine whether two cheap antifolates (chlorproguanil-dapsone and sulfadoxine-pyrimethamine) which work against falciparum malaria in this region are sufficiently effective against vi...
Drug resistance to a range of antimalarial treatments has become widespread in Africa, South East Asia and South America. Because the rapid spread of drug resistance threatens a public hea...
The purpose of the study is to see whether antimalarial drugs administered at the time of routine infant vaccinations prevents malaria and anemia in the first year of life.
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 imm...
The ancient drug dapsone has antimicrobial and anti-inflammatory features. In dermatology, dapsone is primarily used for neutrophil-dominant skin diseases. However, real-life data assessing the long-t...
The main objective of this study was to develop, characterize and evaluate the potential use of dapsone-loaded nanostructured lipid carriers (NLCs) as a topical treatment for acne. Differently charged...

Artesunate (ART) is an artemisinin derivative used as monotherapy for the treatment of severe malaria and in combination with a partner drug for non-severe malaria. Resistance of malaria parasites to ...
A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
Acetylated sulfone that is slowly metabolized to give long-term, low blood levels of DAPSONE. It has antimicrobial and antimalarial action, but is mainly used as a depot leprostatic agent.
Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.
Vaccines made from antigens arising from any of the four strains of Plasmodium which cause malaria in humans, or from P. berghei which causes malaria in rodents.
A protozoan parasite that causes vivax malaria (MALARIA, VIVAX). This species is found almost everywhere malaria is endemic and is the only one that has a range extending into the temperate regions.
