Malaria Anaemia clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Chloroquine and Post Malaria Anaemia Study

CQ-PMA

Start date: July 2007
Phase: N/A
Study type: Interventional

The pathogenesis of post-malaria anaemia is multifactorial. Iron supplementation remains the mainstay of management of moderate and severe anaemia; however the management of mild anaemia (Hb 80-110g/l) is problematic as population supplementation studies of children in malaria endemic areas demonstrate adverse effects in children with mild anaemia. We hypothesize that the anti-inflammatory, anti-malarial and anti-macrophageal iron loading effects of chloroquine could make it a useful drug in the management of mild post malaria anaemia. To test this hypothesis, we plan to randomize children (aged 12 months to 6 years) with post malaria anaemia (Hb 70-110g/l) to receive a standard anti-malarial treatment, co-artemether . All children with parasitologic cure after three days on treatment will be randomised to receive either weekly chloroquine or weekly placebo starting from day 10 till day 90. By comparing the curve of haemoglobin change between day 3 and day 30 in the placebo arms of the two groups, we will test the effect of chloroquine vs. ACT treatment on macrophageal iron loading and release in acute clinical malaria. By comparing the haemoglobin change between day 3 and day 90 between the weekly chloroquine arms and the weekly placebo arms we will test the longer-term anti-inflammatory and anti- malarial effects of weekly chloroquine prophylaxis. In addition to the primary endpoint, we plan to assess potential mechanisms of action by determining parasite clearance, peripheral cytokine production and iron flux
