简要总结
GSK961081 has previously been administered to healthy subjects in a nebulised formulation and the first part of this study which will be conducted in healthy subjects proposes to bridge the change from nebulised to DPI formulation of GSK961081 before administration to patients. The second part of the study will be conducted in COPD patients and aims to assess the safety and bronchodilator profile of GSK961081 over 24 hours, during 14 days dosing.

GSK961081
GSK961081
干预措施: GSK961081 (Drug)
结局指标
主要结局
Part 1: Summary of last observed plasma concentration (t-last), time of maximum observed concentration (t-max) and terminal elimination half-life (t-half)
时间窗: Pre-dose (0.0h) and 15, 30, 45 M, 1, 2, 3, 4, 6, 8, 12 and 24 h post dose of each treatment period
Plasma samples for PK analysis were drawn on D1 at indicated time points. The t-last and t-max was determined directly from the raw concentration-time data after each single dose. The t-half was obtained as the ratio of ln2/lambda z, where ln(2) is the natural logarithm of 2 (approximately 0.693) and lambda z is the terminal phase rate constant estimated by linear regression analysis of the log transformed concentration-time data after each single dose. Data for adjusted mean is presented as least square mean. Only those participants available at the specified time points were analyzed (represented by n=x,x,x in the category titles). Different participants may have been analyzed at different time points; thus, the overall number of participants analyzed reflects everyone in the All Subjects population.
Part 2: Forced Expiratory Volume in 1 second (FEV1) over 24 hours post-dose on D1 and 14
时间窗: Up to D14 of each treatment period (up to 16 weeks)
Lung function tests (FEV1) was recorded whilst the participant was in a sitting position (if taken whilst the participant was on the bed, their legs should be over the edge). All lung function tests was repeated, until three technically acceptable measurements were made. Each measurement should be done at least 1 M apart. Participants must be resting in the body box for at least 30 seconds prior to any assessments. The FEV1 was measured at 15, 30 M, 1, 4, 12 and 24 h post dose of each treatment period on D1 and 14. Data for adjusted mean is presented as least square mean. Only those participants available at the specified time points were analyzed (represented by n=x,x,x,x in the category titles). Different participants may have been analyzed at different time points; thus, the overall number of participants analyzed reflects everyone in the All Subjects population. Data for adjusted mean is presented as least square mean.
Part 1: Summary of area under the GSK961081 concentration-time curve (AUC) after a single dose
时间窗: Pre-dose (0.0 hour [h]) and 15, 30, 45 minutes (M), 1, 2, 3, 4, 6, 8, 12 and 24 h post dose of each treatment period
Plasma samples for PK analysis were drawn on Day (D) 1 at indicated time points. The AUC from time zero (0M) to 2h (AUC 0-2) was area under the plasma concentration-time curve over the 2h time period. AUC(0-6) was area under the plasma concentration-time curve from 0M to 6h. AUC(0-t) was area under the plasma concentration-time curve from 0M to last quantifiable concentration. The AUC extrapolated to infinity (inf) (AUC\[0-inf\]) was calculated as the sum of AUC(0-t) and Ct/lambda z, where Ct is the observed GSK961081 concentration obtained from the log-linear regression analysis of the last quantifiable time-point and lambda z is the terminal phase rate constant estimated by linear regression analysis of the log transformed concentration-time data. The number of time points used in the estimation of lambda z. Different participants may have been analyzed at different time points; thus, the overall number of participants analyzed reflects everyone in the PK population.
Part 1: Summary of maximum observed concentration (Cmax) of GSK961081 after a single dose
时间窗: Pre-dose (0.0h) and 15, 30, 45 M, 1, 2, 3, 4, 6, 8, 12 and 24 h post dose of each treatment period
Plasma samples for PK analysis were drawn on D1 at indicated time points. The first occurrence of the maximum observed GSK961081 concentration determined directly from the raw concentration-time data after each single dose. All participants were present at the time of measurement.
