Study Endpoints
Primary Endpoints
Mean change in controlled attenuation parameter (CAP) score by sound-based elastography at Week 24
Week 24
Mean change from baseline in fasting serum triglyceride levels at Week 24
Week 24
Absolute Change From Baseline in Forced Vital Capacity for 26 Weeks
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
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)
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
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
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.

Mean Change From Baseline at 12 Weeks of MN-001 Treatment on Cholesterol Efflux Capacity
Baseline, 12 weeks

Change from baseline to 12 weeks of MN-001 on Cholesterol Efflux Capacity (CEC) in NAFLD subjects with hypertriglyceridemia. CEC, a key step in reverse cholesterol transport, was inversely associated with the incidence of cardiovascular events and is considered to be a new biomarker to assess cardiovascular risk. Cholesterol efflux was calculated as the percent of cholesterol removed from the cells and appearing in the culture medium normalized to a reference serum pool. The ability of serum HDL to remove cholesterol from cultured cells was assessed as an in vitro method to evaluate functional changes in HDL mediated by changes due to MN-001 treatment.

Mean Change From Baseline to Week 8 on Triglyceride Levels After 8 Weeks MN-001 Treatment
8 weeks

Change from baseline to 8 weeks of MN-001 on serum triglyceride levels in NASH subjects with hypertriglyceridemia

Number Subjects at Least "Moderately Improved" for Each Treatment Group in Patient Reported Global Response Assessment (GRA)
8 weeks

The primary endpoint was the GRA overall change "in their condition" at Week 8. Each patient completed the questionnaire that rated the improvement in their IC symptoms based on responses to the GRA questions. Each question asked the patient to describe the OVERALL CHANGE in pain, urgency, frequency or overall change in their problem compared to the status before taking the study medication. Each parameter was rated on a 7 point scale: markedly worse, moderately worse, mildly worse, same, mildly improved, moderately improved and markedly improved.
