Safety Study of Combined Azithromycin, Ivermectin and Albendazole for Trachoma and Lymphatic Filariasis (AZIVAL2)

May 21, 2014 updated by: Huub Gelderblom MD, PhD, MPH, Emory University

AZIVAL 2: A Double-blind Cluster-randomized Placebo-controlled Study on the Safety of Integrated Treatment of Trachoma and Lymphatic Filariasis in Children and Adults With Azithromycin, Ivermectin and Albendazole

Trachoma and lymphatic filariasis (LF) are two 'Neglected Tropical Diseases' (NTDs), infectious diseases that affect millions of poor people in countries in the developing world. Trachoma is an eye infection that can lead to painful scarring of the eyelids and blindness later in life. LF can lead to swelling of usually the limbs (elephantiasis).

Trachoma and LF are preventable and treatable diseases. One important treatment strategy is annual Mass Drug Administration (MDA): Communities receive drug treatment once a year. Azithromycin is given for trachoma. Ivermectin and albendazole are given for LF.

Trachoma MDA and LF MDA are currently separated campaigns. Combined MDA campaigns for trachoma and LF, where three drugs would be given at one time, would reduce costs and decrease the burden on the health system.

Before combined MDA with three drugs (azithromycin, ivermectin and albendazole) could be recommended, we would have to demonstrate that the safety profile of this treatment with three drugs is acceptable. An earlier study in Mali in 2010 (AZIVAL) comparing standard MDA (one week space between the two MDA campaigns) with combined MDA (trachoma and LF MDA on the same day) showed that the safety profiles were comparable; but the results of the study were not statistically significant and we could not use them to make an official recommendation.

The AZIVAL 2 study has been designed to answer the questions that remain after the AZIVAL study performed in Mali in 2010. If the safety results of the AZIVAL 2 study are acceptable, an official recommendation for combined MDA with azithromycin, ivermectin and albendazole can be drafted.

We will conduct the AZIVAL 2 study in Mozambique. The target population (inclusion and exclusion criteria) is the same as in the AZIVAL study in Mali. Main criteria are: Age ≥ 5 years and ≤ 65 years, height ≥ 90 cm, if female, not pregnant or breast-feeding.

Important differences between the AZIVAL study and the AZIVAL 2 study are a) smaller clusters for sufficient power (average household size is 5 people), b) placebo to double-blind participants and study staff for azithromycin, c) the study area will have undergone fewer previous rounds of MDA for LF and none for trachoma, and d) smartphones for data entry.
