Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by University of Cape Town:

Primary Outcome Measures:
  • Therapeutic efficacy defined as: Adequate Clinical and Parasitological Response (ACPR), Early Treatment Failure (ETF), Late Treatment Failure (LTF), defined as Late Clinical Failure (LCF) and Late Parasitological Failure (LPF)
  • Sensitive or parasitological failure (RI, early and late, RII, RIII)
  • Parasitological failures will be classified as recrudescence or re-infection (or indeterminate) using GLURP and MSP I & II markers
  • Parasite clearance time
  • Fever clearance time

Secondary Outcome Measures:
  • Association between study treatment and gametocyte carriage
  • Pharmacokinetics by measurement of whole blood levels of Sulfadoxine and Pyrimethamine
  • Correlation of frequency of DHFR and DHPS mutations with parasitological outcome
  • Tolerability by describing adverse events and changes in haematological parameters
  • Capacity by describing the training and development of study teams

Estimated Enrollment: 240
Study Start Date: January 2003
Estimated Study Completion Date: October 2003
Detailed Description:
Resistance of Plasmodium falciparum to anti-malarial drugs is a serious impediment to malaria control. In the South East African Combination Anti-malarial Therapy (SEACAT) evaluation, there is an evaluation of the phased introduction of combination anti-malarial therapy (CAT) in Mozambique, Swaziland and South Africa. In order to facilitate formulation of effective regional drug policy and provide a database for decision-making on the implementation of CAT, it is essential that the in vivo response to CAT be investigated. This will be achieved through the SEACAT 01 protocol which is a component of the SEACAT evaluation described in another file on this website. However, in selected Mozambique sites where the intensity of malaria transmission is high, a direct parallel group comparison of monotherapy (SP) with CAT (artesunate, AS, plus SP) will be conducted according to a specific amendment (Amendment 4) to the SEACAT 01 protocol. Amendment 4 is presented in this separate file on the website for clarity.
