PK PD Study of IDA and Azithromycin for NTDs ( ComboNTDs )

A Pharmacokinetic and Pharmacodynamic Evaluation of Co-Administration of IDA (Ivermectin, Diethylcarbamazine and Albendazole) & Azithromycin for Integrated Treatment of Neglected Tropical Diseases

This is a Pharmacokinetic and Pharmacodynamic study evaluating the safety of co-administering Azithromycin alongside the new IDA (Ivermectin, Diethylcarbamazine, Albendazole) combination treatment for LF. Individuals will be randomised to receive Azithromycin alone, IDA or combination therapy. Clinical and biochemical monitoring for safety will be undertaken. Drug levels will be measured in each of the three arms to assess whether combination therapy significantly alters drug levels.
