简要总结
The purpose of this study is to evaluate the efficacy and safety of delpazolid add-on therapy in Patients with Refractory Mycobacterium abscessus Complex Pulmonary disease
详细描述
Delpazolid, which demonstrates effects similar to other oxazolidinone-class drugs and has confirmed good safety, aims to evaluate its efficacy in MABC-PD patients who are unresponsive to guideline-based treatments

研究组 & 干预措施
delpazolid
In addition to background therapy for MABC, patients will be given orally three tablets (400 mg/tablet) of LCB01-0371 for 12 weeks.
干预措施: Delpazolid (Drug)
结局指标
主要结局
semi-quantitative scale (SQS) change versus baseline
时间窗: 12 weeks
The SQS using liquid media and solid media will be scored a point of 1-7, with lower scores representing a reducing bacterial load.
次要结局
- Change from baseline in SQS(4 weeks and 8 weeks)
- Sputum culture conversion rate(12 weeks)
- Time to culture conversion(12 weeks)
- Time to positivity in the liquid culture automated system (MGIT)(12 weeks)
- Negative sputum culture rate at each time point after baseline(12 weeks)
- Change from baseline in the inflammatory marker(12 weeks)
- Change from baseline in the CT score(12 weeks)
- Quality of Life Questionnaire-Bronchiectasis(12 weeks)
- Six-minute walk test(12 weeks)
- Extended administration(After 12 weeks)
