Short-term Antibiotic Therapy in Mycobacterium Avium Complex Pulmonary Disease

brief summary

The goal of this clinical trial is to learn if adding contezolid works to shorten the length of treatment in mycobacterium avium pulmonary disease in adults. It will also learn about the safety of extended usage of contezolid. The main questions it aims to answer are: Does adding contezolid to standard regimen decrease the bacterial load, lesion severity and improve the life quality of patients with mycobacterium avium pulmonary disease? What medical problems do participants have when taking contezolid for an extended length? Researchers will compare standard regimen plus contezolid to standard regimen alone to see if contezolid helps further decrease the bacterial load, lesion severity and improve the life quality of patients with mycobacterium avium pulmonary disease? Participants will: Take contezolid and standard regimen (azithromycin, ethambutol, and rifampicin) for 6 months, contezolid is administered every day while other drugs are taken three times a week OR take standard regimen three times a week for 12 months. Visit the clinic once every 1 month for checkups and tests.
