Summary

An antimalarial drug efficacy trial was conducted for artemether-lumefantrine (AL) and chloroquine (CQ) in the three (3) municipalities (Bataraza, Brookes and Rizal) of Palawan. Study subjects are febrile individuals between \> 6 months old and 59 years old with confirmed uncomplicated P. falciparum or P. vivax infections. Patients with P. falciparum was treated with Artemether-lumefantrine administered 3 days (Days 0, 1 and 2) according to body weight. Primaquine at 0.75 mg base/kg body weight single dose was given on Day 3. For Plasmodium vivax patients chloroquine were administered according to body weight at a total dose of 25 mg/kg over 3 days (10 mg/kg on Day 0; 10 mg/kg on Day 1 and 5 mg/kg on Day 2), and primaquine following the National Treatment Guidelines.

During the period that this report covers, 84 and 75 patients met the inclusion criteria for Pf and Pv respectively. Clinical and parasitological parameters were monitored over a 28-day follow-up period for both drugs.

The presence of only 1 Late Clinical Failure (LCF) of P. falciparum parasitemia out of 84 enrolled patients and 2 Late Parasitological Failure (LPF) of P. vivax patients out of 75 enrolled patients within the 28 days follow up suggest that both drugs are still efficacious.
