Evaluate Azithromycin Plus Chloroquine And Sulfadoxine Plus Pyrimethamine Combinations For Intermittent Preventive Treatment Of Falciparum Malaria Infection In Pregnant Women In Africa

A Phase 3, Open Label, Randomized, Comparative Study To Evaluate Azithromycin Plus Chloroquine And Sulfadoxine Plus Pyrimethamine Combinations For Intermittent Preventive Treatment Of Falciparum Malaria Infection In Pregnant Women In Africa

The primary objective is to establish superiority of AZCQ over SP in protective efficacy for IPTp as measured by the proportion of subjects with sub-optimal pregnancy outcome.

After interim analysis of efficacy data by an External Data Monitoring Committee, this study was terminated. Investigators were notified on 22 Aug 2013. There were no safety concerns that led to this termination.

• Requirement to use medication during the study that might interfere with the evaluation of the study drug eg, trimethoprim-sulfamethoxazole use in subjects positive for HIV infection.
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation.
