The primary end point was parasitologic cure at Day 28.Results: In India, parasite clearance rates were 84% and 94% for AZCQ and SPCQ, respectively (95% confidence interval [CI] for the difference: –22.6, 0.8). In Colombia and Suriname, parasite clearance rates were 57% and 99% for AZCQ and AP, respectively (95% CI: –52, –32). A subsequent open-label, non-comparative third study using a 2g dose of azithromycin and 600mg of CQ in India and Colombia resulted in an overall efficacy rate of 97%.Conclusion: In India, Colombia, and Suriname, 1g azithromycin with CQ QD for 3days was inferior to established comparator agents. An improved response rate was observed when the dose of azithromycin was increased to 2g.
