Clinical Study on the Early Bactericidal Activity of Contezolid Against Mycobacterium Abscessus Disease

Enrolling by invitation · Phase 2

Conditions studied: Monotherapy, Mycobacterium Abscessus Infection

In brief

This study is a single-center, randomized, controlled, open-label clinical trial designed to assess the early bactericidal activity of a single agent, contezolid, in patients with Mycobacterium abscessus infections. Patients were administered contezolid monotherapy for 14 days specifically targeting Mycobacterium abscessus, and were compared to a control group receiving linezolid, a classic anti-Mycobacterium abscessus drug. The comparison was conducted through the analysis of colony forming units counts and Time To Positivity in sputum cultures. By evaluating the impact of contezolid monotherapy on the bacterial load in the sputum of patients with Mycobacterium abscessus infections, this study aimed to assess the early bactericidal activity of contezolid, thereby providing a basis for the selection of new therapeutic options for the treatment of patients with Mycobacterium abscessus infections.
