A Safety, Tolerability and Efficacy Study in Chronic Obstructive Pulmonary Disease (COPD) Patients With QBM076.

Study Overview
=================
Brief Summary
-----------------
This was a 2 Part study. Part 1 was a safety and tolerability study in GOLD I-III COPD patients. Part 2 was an efficacy study in GOLD I-III COPD patients.

Detailed Description
-----------------
Part 1 was a double-blind, randomized, placebo-controlled, non-confirmatory study in chronic bronchitis COPD patients. Part 1 consisted of up to 27-days of screening period, one baseline period of 1 day, 13 days of bid dosing with study treatment, morning only treatment on Day 14, follow up visits on Days 15 - 17, followed by a Study Completion evaluation. Twenty-seven patients were randomized in a 3:1 ratio to 3 cohorts.. Part 2 was a double-blind, randomized, placebo-controlled, non-confirmatory study in Gold spirometry grades I-III COPD patients. Part 2 consisted of up to 20 days of screening period, a 9 day run in period, one baseline period of 1 day, 55 days of bid dosing, morning only dosing on Day 56, followed by Study Completion evaluation. It was planned to randomize 90 patients in a 2:1 ratio, but part 2 was terminated after 21 patients were enrolled. Three of the 21 part 2 patients experienced moderate to severe (up to 17-fold) asymptomatic and reversible elevation of liver transaminase levels after 3 weeks of treatment with QBM076 150 mg twice daily. Two of these patients had liver transaminase levels high enough to be reported as serious adverse events suspected to be related to the study drug.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Events (Part 1) | Adverse events were counted and corresponding percentages were tabulated. | 14 days | 
| Change From Baseline in Lung Clearance Index (LCI) (Part 2) |  | Baseline, 8 weeks | 
| Change From Baseline in Absolute Number of Sputum Neutrophils (Part 2) |  | Baseline, 8 weeks | 
| Change From Baseline in Transition Dyspnea Index (TDI) (Part 2) |  | Baseline, 8 weeks | 
| Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) (Part 2) |  | Baseline, 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Forced Expiratory Volume in One Second (FEV1) (Part 1) | FEV1 is the amount of air that can be exhaled in one second. FEV1 will be measured by spirometry and performed at approximately the same time of day on each visit to avoid diurnal variation. All spirometry calibrations and evaluations followed the recommendations of the American Thoracic Society / European Respiratory Society guidelines for acceptability. A positive change from baseline in FEV1 indicates improvement in lung function. | baseline, day 14 pre-dose | 
| Change From Baseline in Lung Clearance Index 2.5 (LCI2.5) (Part 1) | Lung clearance index (LCI) is a measure of abnormal ventilation distribution derived from the multiple breath inert gas washout (MBW) technique. LCI is equal to the cumulative expired volume/functional residual capacity. LCI was measured at baseline and day 14. LCI was analyzed using a Bayesian model for repeated measurements. The model may investigate effects for pre-dose baseline, treatment, time, age, COPD class, treatment by time interaction, and baseline by time interaction. A positive change from baseline indicates improvement. | baseline, day 14 pre-dose | 
| Change From Baseline in Forced Expirtory Flow 25-75 (FEF25-75), Forced Expiratory Volume 3 (FEV3)/Forced Vital Capacity (FVC), 1-(FEV3/FVC), FEV6, FEV1/FEV6 and Post-bronchodilator Forced Expiratory Volume in 1 Second (FEV1) (Part 2) |  | baseline, day 56 | 
| AUC0-24 (Part 2) |  | day 1, day 56 | 
| Cmax Between 0h and 24h (Part 2) |  | day 1, day 56 | 
| Tmax Between 0h and 24h (Part 2) |  | day 1, day 56 | 
| Change From Baseline in Percentage Sputum Neutrophils (Part 2) |  | baseline, day 56 | 
| Change From Baseline in Diffusing Capacity of the Lung for Carbon Monoxide (DLco) (Part 2) |  | baseline, day 56 | 
| Change From Baseline in Scond/Sacin as Measured by Multiple Breath Nitrogen Washout (MBNW) (Part 2) |  | baseline, day 56 | 
| Area Under the Plasma Concentration-time Curve From Time Zero to the End of the Dosing Interval, Tau (AUCtau) (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 1 (from pre-dose to 12 hours post dose) | 
| AUCtau, Steady State (AUCtau,ss) (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 14 (from pre-dose to 72 hours post dose) | 
| Observed Maximum Plasma Concentration Following Drug Administration (Cmax) (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 1 (from pre-dose to 12 hours post dose) | 
| Cmax,ss (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 14 (from pre-dose to 72 hours post dose) | 
| Time to Reach the Maximum Concentration After Drug Administration (Tmax) (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 1 (from pre-dose to 12 hours post dose) | 
| Tmax,ss (Part 1) | Venous blood samples were collected for concentration-time profiles. | day 14 (from pre-dose to 72 hours post dose) | 
| Change From Baseline in Cluster of Differentiation 11b (CD11b) (Part 1) | Whole blood samples were taken by either direct venipuncture or an indwelling cannula inserted in a forearm vein in order to measure CD11b expression on neutrophils. A negative change from baseline indicates improvement. | baseline, day 14 | 
| Change From Baseline in Chemokine (C-X-C Motif) Receptor 2 (CXCR2) Receptor Occupancy (Part 1) | Whole blood samples were taken by either direct venipuncture or an indwelling cannula inserted in a forearm vein in order to measure CXCR2 receptor occupancy on neutrophils. A positive change from baseline indicates improvement. | baseline, day 14 |
