About this trial
The goal of this clinical trial is to learn if cordyceps sinesis capsule (Bailiing Capsule) works to prevent the recurrence of microbiologically cured mycobacterium avium complex pulmonary disease in adults. The main questions it aims to answer are:
Does cordyceps sinesis capsule (Bailiing Capsule) prevents the recurrence of mycobacterium avium complex pulmonary disease in adults? Researchers will compare cordyceps sinesis capsule (Bailiing Capsule) to a placebo (a look-alike substance that contains no drug) to see if cordyceps sinesis capsule helps to prevent the recurrence of mycobacterium avium complex pulmonary disease.
Participants will:
Take cordyceps sinesis capsule (Bailiing Capsule) or a placebo (a look-alike substance that contains no drug) for 12 months, both are administered every day.
Visit the clinic once every 3 months for checkups and tests. Take online questionnaires every month.
