Run by Leiden University Medical Center · NCT06222372 · Data updated 2026-11-12

This study is testing new ways to find and prevent leprosy in people who have been close to someone diagnosed with it, using a single-dose antibiotic and a new test to spot the disease early.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include newly diagnosed multibacillary leprosy patients and their close contacts living in the same household or community.

Probably not a fit

Patients with the pure neural form of leprosy or those living too far from diagnosed patients may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study focuses on identifying asymptomatically infected individuals with Mycobacterium leprae to prevent the transmission of leprosy. It evaluates the effectiveness of post-exposure prophylaxis using single-dose rifampicin (SDR) in contacts of newly diagnosed leprosy patients. The study also employs a novel lateral flow assay to assess immune responses specific to leprosy, aiming to improve early detection and treatment strategies. By integrating these methods into routine leprosy control programs, the study seeks to enhance public health outcomes in endemic regions.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of leprosy by enabling early detection and treatment of at-risk individuals.

How similar studies have gone: Previous studies have shown promise in using prophylactic treatments like SDR for leprosy prevention, indicating a potential for success in this approach.
