Leprosy Skin Test Antigens Trial

Summary

The purpose of this study is to see how healthy people and leprosy patients react to 2 new skin tests for detecting leprosy. The study will evaluate the new skin tests that may aid in measuring the number of people exposed to leprosy and enable its diagnosis and treatment at an earlier stage. Participant's ages 18-60 living in Kathmandu, Nepal will be enrolled. Stages A and B of the study will use the skin test in healthy volunteers. Stage C will use the skin test in high risk volunteers (including individuals with leprosy), healthy individuals in contact with leprosy patients and individuals with tuberculosis (TB, lung disease). Study procedures will include injections, physical exam, and blood testing. Injection sites will be checked several times during the participant's study involvement (5 hours of time spread over approximately 1 month). Volunteers screened for the study, which have leprosy or tuberculosis will be treated or referred for treatment.
