Abstract | Background: Although trichuriasis affects millions of children worldwide, recommended drugs lack efficacy and new treatment options are urgently needed. Ivermectin has promising potential to complement the anthelminthic armamentarium. Methods: A randomized placebo-controlled trial was conducted in rural Côte d'Ivoire to provide evidence on the efficacy and safety of ascending oral ivermectin dosages in preschool-aged children (PSAC) and school-aged children (SAC) infected with Trichuris trichiura. The primary outcome was the cure rate (CR) for T. trichiura infection, and the secondary outcomes were safety, egg-reduction rates (ERRs) against T. trichiura infection, and CRs and ERRs against other soil-transmitted helminth species. Results: A total of 126 PSAC and 166 SAC were included in an available case analysis. In PSAC, efficacy against T. trichiura did not differ between 200 µg/kg ivermectin and placebo treatment arm, as expressed in CRs (20.9% [95% confidence interval {CI}, 11.9%-52.8%] vs 19.5% [10.4%-49.9%]) and geometric mean ERRs (78.6% [60.1%-89.5%] vs 68.2% [40.5%-84.8%]). In SAC, the highest administered ivermectin dose of 600 µg/kg had a low CRs (12.2% [95% CI, 4.8%-32.3%]) and moderate ERRs (66.3% [43.8%-80.2%]). Only mild adverse events and no organ toxicity, based on serum biomarkers, was observed. Conclusion: Clinical Trials Registration: ISRCTN15871729 (www.isrctn.com).
