简要总结
This is a randomized, placebo-controlled, double-blind, 6-month study followed by a 6-month open-label extension phase to evaluate the efficacy, safety, and tolerability of MN-001 in patients diagnosed with moderate to severe idiopathic pulmonary fibrosis (IPF). Participants were randomly assigned to receive MN-001 or matching placebo twice daily over a 26-week period. A total of 15 participants were enrolled.
详细描述
This study was a single-center, randomized (2:1), placebo-controlled, double-blind, 6-month study followed by a 6-month open-label extension (OLE) phase in patients with moderate to severe IPF. Major inclusion criteria: physician diagnosed IPF (ATS Guidelines, 2011), males and females aged 21 to 80 years, GAP Stage II-III; on no anti-fibrotic treatment. Patients on stable dose of nintedanib for at least 3 months prior to the study were allowed. The study consisted of a Screening Phase (up to 3 months prior to Day1), a 26- week Double-Blind Treatment (DBT) period, a 26-week Open-Label Extension (OLE) period, and a Follow-up / End of Study Visit (within 4 weeks of the last dose taken). A total of 15 patients were enrolled in the study. During the DBT period, participants were randomly assigned to receive MN-001 750 mg twice daily or a matching placebo in a 2:1 ratio (MN-001: placebo) for 26 weeks. During the OLE period, all participants received MN-001 750 mg twice daily for 26 weeks. Taken together, participants (n=15) received either MN-001 50 mg twice daily for 12 months (MN-001/MN-001) or matching placebo for 6 months and MN-001 750 mg twice daily for 6 months (Placebo/MN-001).

结局指标
主要结局
Absolute Change From Baseline in Forced Vital Capacity for 26 Weeks
时间窗: Baseline and Week 26 at the end of Double-blind treatment period.
Predicted forced vital capacity (FVC) is a reference value for lung function based on your age, height, sex, and ethnicity measured by a spirometer and is an established method of pulmonary function. FVC is the volume of air that can be forcibly blown out after full inspiration, measured in liters (L).
Percent Change in Forced Vital Capacity From Baseline to Week 26
时间窗: Baseline, and Week 26 at the endpoint of the Double-blind treatment period.
FVC is the volume of air that can be forcibly blown out after full inspiration, measured in liters (L). The mean relative change was calculated as 100\*\[FVC (L) at Week 26 - FVC (L) at baseline\].
Absolute Change From Baseline in Forced Vital Capacity (% Predicted)
时间窗: Baseline and Week 26 at the end of Double-blind treatment period.
FVC(%pred.) refers to the expected FVC for a healthy individual with the same age, sex, height, and weight. The actual FVC result is then expressed as a percentage of this predicted value; values of 80% or higher are generally considered normal and indicate no significant impairment.
Relative Change From Baseline in Percent Predicted Forced Vital Capacity From Baseline to Week 26
时间窗: Baseline and Week 26 at the end of Double-blind treatment period.
FVC (%pred/) refers to the expected FVC for a healthy individual with the same age, sex, height, and weight. The actual FVC result is then expressed as a percentage of this predicted value; values of 80% or higher are generally considered normal and indicate no significant impairment. Relative change is measured as percent (%) change from FVC (%pred.).
Semiannual Rate of Decline of Disease Activity Based on Forced Vital Capacity
时间窗: Baseline and Week 26 at the end of Double-blind treatment period.
The semiannual rates of change in FVC, measured in liters, were estimated using simple linear regression, with time measured in half-years.
次要结局

- Change From Baseline on Disease Activity Based on Modified Medical Research Council Dyspnea Score(Baseline, and Week 26 at the endpoint of the Double-blind treatment period)
- Change From Baseline on Quality of Life (QOL) Measured by A Tool to Assess Quality of Life in Idiopathic Pulmonary Fibrosis(Baseline, and Week 26 at the endpoint of the Double-blind treatment period)
