Trachoma Amelioration in Northern Amhara (TANA)
This study is currently recruiting participants.
Verified by University of California, San Francisco, April 2008
Sponsored by: University of California, San Francisco
Information provided by: University of California, San Francisco
ClinicalTrials.gov Identifier: NCT00322972
  Purpose

The WHO has initiated a program to eliminate trachoma, blinding eye infection caused by Chlamydia trachomatis, in large part by mass distributions of oral azithromycin. The proposed study will determine the frequency and treatment target of community-wide mass antibiotic treatment. We will also study the impact of mass antibiotic distribution on antibiotic-resistance in pneumococcus.


Condition Intervention Phase
Trachoma
Chlamydia
Drug: Mass treatment with oral azithromycin to an entire community
Phase IV

Study Type: Interventional
Study Design: Treatment, Randomized, Single Blind, Dose Comparison, Parallel Assignment, Safety/Efficacy Study
Official Title: Eliminating Trachoma With Repeat Mass Drug Treatment

Further study details as provided by University of California, San Francisco:

Primary Outcome Measures:
  • The average prevalence of ocular chlamydia infection in communities in an arm as determined by pooled NAAT (Nucleic Acid Amplification Test)(at 42 months for Aim 1, at 12 months for Aim 2, post-treatment relative to pre-treatment for Aim 3)

Secondary Outcome Measures:
  • Clinical active trachoma in community, as determined by the WHO simplified grading system
  • Childhood (>= 1 year of age) mortality, analyzed as 1-5, 6-10 years of age, and total
  • Macrolide resistance in pneumococcus (% resistance over time, clustered by randomization unit)

Estimated Enrollment: 36000
Study Start Date: June 2006
Estimated Study Completion Date: November 2009
Estimated Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
A
Annual mass treatment
Drug: Mass treatment with oral azithromycin to an entire community
B
Biannual mass treatment
Drug: Mass treatment with oral azithromycin to an entire community
C: Experimental
Mass administration of antibiotic; treatment of children (1-10 years of age) only
Drug: Mass treatment with oral azithromycin to an entire community
D: No Intervention
Delayed initiation of mass administration of antibiotic
Drug: Mass treatment with oral azithromycin to an entire community
F
One-time mass administration only
Drug: Mass treatment with oral azithromycin to an entire community
G: Experimental
One-time mass administration of antibiotics, plus intensive latrine construction
Drug: Mass treatment with oral azithromycin to an entire community

Detailed Description:

The proposed study is a group-randomized trial to determine the frequency and treatment target of community-wide mass antibiotic treatment to eliminate trachoma. We will also study the impact of community-wide antibiotic distribution on antibiotic-resistance in pneumococcus. Communities in Goncha Siso Enese district of East Gojam Zone, Ethiopia will be randomly assigned to different treatment schemes and monitored to study the following research questions:

Specific Aim 1. To determine whether biannual mass treatments is more likely to eliminate ocular chlamydia from hyper-endemic communities than annual mass treatments.

Specific Aim 2. To determine whether children form a core group for the transmission of trachoma.

Specific Aim 3. To determine whether latrine construction prevents the return of infection into a community after mass treatment.

Specific Aim 4. To determine the effect of mass azithromycin treatments on antibiotic resistance in pneumococcus and the reduction in mortality.

  Eligibility

Ages Eligible for Study:   1 Year and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

• All residents residing in the state-teams which are randomly selected for this study.

Exclusion Criteria:

  • Pregnant women
  • Children under 6 months of age
  • All those who are allergic to macrolides or azalides
  • Refusal of village chief (for village inclusion), or refusal of parent or guardian (for individual inclusion)

Individuals in these three exclusion criteria will not be given the study antibiotic azithromycin, but offered the current WHO-recommended alternative treatment to azithromycin for active trachoma, which is 1% tetracycline eye ointment, to be used twice a day, topically to both eyes, for six weeks. Note that the exclusion criteria refer to the exclusion to the treatment drug, but not to the monitoring, treatment of trachoma, and examinations.
