Azithromycin Plus Chloroquine Versus Sulfadoxine-Pyrimethamine Plus Chloroquine For The Treatment Of Uncomplicated, Symptomatic Falciparum Malaria In Southeast Asia
Phase 2
Terminated
- Conditions
- Malaria, Falciparum
- Registration Number
- NCT00084240
- Lead Sponsor
- Pfizer
- Brief 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.
- Detailed 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.

Inclusion Criteria
- Females and males >=18 years of age with uncomplicated, symptomatic malaria as indicated by the presence of both of the following: a.)

- 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

- 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
