VL Surveyor

Discover the first interactive online tool that displays the details of visceral leishmaniasis (VL) clinical trials across geographic locations and time.

The VL Surveyor is an online interactive map that summarises VL clinical trials across the world. The tool provides a clear and standardised visualisation of VL clinical trials to date to inform key international, regional and national monitoring strategies, and future studies.

The data included in the surveyor are derived from a systematic review of VL clinical trials and are updated every six months.

The VL Surveyor:

  • Contains summary data from 180 clinical trials registered and/or published since 1983 (over 30,000 patients)
  • Allows you to perform custom searches of a large number of studies and view summary results
  • Enables you to filter results by country, time range and drug(s).
