Clinical Trial Summary

The primary objective is to confirm the hypothesis that azithromycin (optimal dose once daily for three days) plus chloroquine is non-inferior to sulfadoxine-pyrimethamine plus chloroquine for the treatment of uncomplicated, symptomatic malaria due to P. falciparum.


Description:

The trial was terminated prematurely 2 June 2005 due to the inability to recruit the planned number of subjects. There were no safety or efficacy concerns regarding the study in the decision to terminate the trial.

- Serum glucose >= 60 mg/dL (by fingerstick or peripheral blood collection)

- Positive rapid diagnostic test (Binax NOW ICT) for P. falciparum

- Women of childbearing potential must have a negative urine gonadotropin prior to entry into the study and must agree to use adequate contraception during the entire study

Exclusion Criteria:

- Severe or complicated malaria including subjects with any of the following: a.) Impaired consciousness, seizures or abnormal neurologic exam b.) Jaundice c.) Respiratory distress d.) Persistent vomiting e.) Hematuria, as reported by the patient f.) Parasite density > 100,000 parasites/mL g.) Presence of non-falciparum species on microscopy

- Pregnant or breast-feeding women

- History of allergy to or hypersensitivity to azithromycin or any macrolide, sulfonamides, pyrimethamine, or chloroquine

- Known history of blood dyscrasias (e.g., megaloblastic anemia, agranulocytosis, aplastic anemia, thrombocytopenia, leukopenia, neutropenia, hemolytic anemia)

- History of epilepsy or psoriasis

- History of treatment with any antimalarial drug (chloroquine, quinine, mefloquine, Malarone, SP, artemisinin compounds) or antibacterial with known antimalarial activity (macrolides, doxycycline, clindamycin) within 2 weeks prior to enrollment into the study

- Known or suspected cardiovascular, hepatic or renal abnormality that in the opinion of the Investigator would place the subject at increased risk to participate in the study. The following findings are specific exclusions: a.) serum creatinine > 2.0 x ULN b.) ALT and/or AST > 3 x ULN

- Inability to swallow oral medication in tablet form

- Treatment with other investigational drugs within 30 Days prior to enrollment into the study

- Alcohol and/or any other drug abuse

- Requirement to use medication during the study that might interfere with the evaluation of the study drug (nelfinavir, digoxin, ergot alkaloids, terfenadine, cyclosporine, hexobarbital and phenytoin)

- Specific systemic diseases or other medical conditions that would interfere with the evaluation of the therapeutic response or safety of the study drug

- Inability to comprehend and/or unwillingness follow the study protocol

- Intentions to leave the vicinity of the trial site in the next 42 days
