TRIAL DESCRIPTION
Public title Evaluation of Effect of Stopping Mass Azithromycin Treatment after five years
Official scientific title Evaluation of Effect of Stopping Mass Azithromycin Treatment after five years: a cluster randomized trial
Brief summary describing the background
and objectives of the trial
The GET 2020 Alliance aims to eliminate blinding trachoma by the 2020. In districts where the prevalence of the trachoma indicator trachomatous inflammation-follicular (TF) is ¿ 10% in children ages 1-9 years, the entire population is treated yearly with azithromycin as part of the WHO-endorsed SAFE strategy for trachoma control. Where baseline prevalence of TF is very high, studies have shown that the prevalence of TF remains high even after multiple years of treatment; lab tests in these areas show that the prevalence of infection with Chlamydia trachomatis is very low, indicating that few people may be benefiting from subsequent treatment with azithromycin. This study aims to monitor TF and infection prevalence in districts that have received at least 5 annual rounds of treatment with azithromycin.

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person
allocating the participants to the intervention arms
Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Districts were randomized to one of two study arms using block randomization with a block size of 2 Allocation of districts to arms will be undertaken by an independent epidemiologist using block randomization to ensure a blanced number of districts across the two trial arms a block size of two was used. Open-label (masking not used)

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Control group Control Full SAFE trachoma strategy as per WHO guidelines 13 Active
Experimental group S, F & E arm Districts randomized to this arm will receive the Surgery, Facial Cleanliness/Health Education and Environmental Improvement components of the SAFE strategy but will not receive the Antibiotic component 14

ELIGIBILITY CRITERIA
List inclusion criteria List exclusion criteria Min age Max age Gender
All districts in West Amhara that have completed five or more annual rounds of MDA with azithromycin and have been surveyed for impact will be eligible for inclusion into the study. Districts where SAFE has been implemented for less than 5 years or where impact evaluations have showed prevalence of TF in children 1-9 years to be below 10% will not be included into the study. In the excluded districts, the SAFE strategy will be continued as per the WHO standards and national guidelines. 1 Year 99 Years Both
