ClinConnect Summary

This clinical trial is looking at a new skin test called EEC, which is being studied to help diagnose tuberculosis (TB). The trial is divided into two parts. In the first part, adults aged 18 to 65, including both healthy individuals and those with TB or other lung diseases, will receive either a low or high dose of the EEC skin test. The researchers want to find out which dose works best and how safe it is. In the second part, children aged 3 to 17 and older adults aged 66 to 75 will also receive the skin test to evaluate its safety and effectiveness.

To participate, healthy individuals should be between 3 to 75 years old and have no history of TB. TB patients must have a confirmed diagnosis of the disease, while those with non-TB lung diseases must be between 18 to 65 years old. All participants and their guardians must agree to join the study and be willing to attend follow-up visits. If you join the trial, you can expect to receive injections in both arms, and the researchers will carefully monitor your health and the results of the skin tests. This study is currently recruiting participants, and your involvement could help improve TB diagnosis for everyone.
