研究概览
简要总结
This is a randomized, placebo-controlled, 2-period crossover, escalating repeat dose study, aiming to investigate whether higher potency of different inhaled corticosteroid confers an improvement in the topical efficacy to systemic activity ratio in asthmatic subjects. It will compare the dose response for topical efficacy via airway responsiveness (to adenosine-5'-monophosphate [AMP] challenge), and the dose response for systemic activity via 24 hour plasma cortisol suppression, and thereby compare the relative therapeutic index, for the following inhaled corticosteroids: fluticasone furoate (FF), fluticasone propionate (FP) and budesonide (BUD). There will be a screening visit 4 - 42 days before the first dose of study treatment, and AMP challenge Provocative concentration 20 (PC20) of <=80 milligrams per milliliter (mg/mL) at screening visit 2 i.e. at 4 - 14 days before the first dose of study treatment. Subjects will be randomized to one of 5 or 12 treatment sequences, and will have one or two treatment periods, each comprising 5 consecutive 7-day phases of escalating doses of either FF, FP, BUD or placebo. There will be a 25- to 42-day washout period between treatment periods. The study duration for each subject will be approximately 13 or 24 weeks including the follow-up period.

- •A history of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest or hypoxic seizures within the last 5 years. - Other significant pulmonary diseases to include (but not limited to) severe pneumonia within 6 months of the screening visit, pneumothorax, atelectasis, pulmonary fibrotic disease, bronchopulmonary dysplasia, chronic bronchitis, emphysema, chronic obstructive pulmonary disease, tuberculosis or other respiratory abnormalities other than asthma. - Culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear within 4 weeks of screening that: In the opinion of the investigator, is expected to affect the subject's asthma status or the subject's ability to participate in the study. - A subject will not be eligible if he/she has clinical visual evidence of oral candidiasis at screening. - Any asthma exacerbation requiring oral corticosteroids within 12 weeks of screening or that resulted in overnight hospitalization requiring additional treatment for asthma within 6 months prior to randomization. - Use of prohibited medications including, anti-depressant drugs, and anti-asthma drugs (other than short acting inhaled beta-agonists supplied as rescue medication, oral contraceptives, non-steroidal anti-inflammatory drugs, stable doses of antihistamines, and paracetamol) for 1 week prior to screening and throughout the course of the study. Anti-histamines should be withheld 4 days prior to AMP challenge; subjects must also be able to abstain from short acting inhaled beta-agonists, for 8 hours prior to spirometry. - Subjects undergoing de-sensitization therapy - Current smokers who smoke > 20 cigarettes per week or the equivalent unit dose of other tobacco products or e-cigarettes, or smokers with a smoking history of >=10 pack years. - History of regular alcohol consumption exceeding 21 units per week for men and 14 units per week for females (1 unit =5 ounces [150 mL] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of spirits) within 6 months of screening. - All subjects who are currently or in the last month have worked night-shifts are excluded from the study - Exposure to more than four new chemical entities within 12 months prior to the first dosing day or received an investigational product within 30 days of study start, or 5 half-lives of study drug if that is longer. - A subject has any clinically significant, uncontrolled condition or disease state that, in the opinion of the investigator, would put the safety of the subject at risk through study participation or would confound the interpretation of the study results if the condition/disease exacerbated during the study. (e.g. stroke or myocardial infarction within 3 months, uncontrolled hypertension, congestive heart failure, uncontrolled diabetes mellitus.) - Evidence of cancer or history of cancer in the past 5 years other than adequately treated basal or squamous cell carcinoma of the skin or adequately treated in situ carcinoma of the cervix. - Pregnant females as determined by positive urine HCG test at screening or by positive urine HCG test prior to dosing and lactating females. - Subjects with active or chronic infections including hepatitis B or C, human immunodeficiency virus.

Known or suspected sensitivity to the constituents of FF, FP or BUD (i.e., lactose or magnesium stearate etc.) Historical Allergy defined as history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation. - Significant abnormality in the 12-lead electrocardiogram (ECG) performed at screening. The mean of the three individual ECGs will be taken. Mean QT interval corrected for heart rate (QTc) >450 millisecond (msec) for males or QTc>470 msec for female subjects and >480 in subjects with bundle branch block. The QTc is the QT interval corrected for heart rate according to Fridericia's formula (QTcF).

结局指标
主要结局
Provocative Concentration (PC) of Adenosine 5' Monophosphate (AMP) Causing a 20 Percent (%) Reduction in Forced Expiratory Volume in 1 Second (FEV1) (AMP PC20)- Dose Response Analysis
时间窗: 12 hours post last dose on Day 7
The percentage fall in FEV1 was calculated using highest FEV1 (post saline) minus highest FEV1 (post AMP) divided by highest FEV1 (post saline)\*100 where highest FEV1 (post saline) is the highest value of two FEV1 measurements at 60 and 180 seconds after the saline control, highest FEV1 (post AMP) is the highest value of the two FEV1 measurements at 60 and 180 seconds after the dose of AMP. Results are presented treatment wise. The analysis method was a 3 parameter Emax model with log 2 transformed AMP PC20 as the outcome variable, assuming common Emax across FF, FP and BUD, and with an unstructured variance-covariance matrix. Mean and 95% Confidence Interval (CI) presented are predicted estimate.
Cortisol Suppression 0-24 Hours Weighted Mean-Dose Response Analysis
时间窗: Pre-dose PM dose on Day 6 to pre-dose PM dose Day 7
Blood samples for measurement of plasma cortisol were collected at given time point. The weighted means were derived by calculating the area under the curve (AUC) over the 0-24-hour period using the trapezoidal rule, and then dividing it by the actual time interval. Results are presented treatment wise. Mean and 95% CI presented are predicted estimate. The analysis method was an inhibitory exponential power-law model with log e transformed cortisol as the outcome variable, assuming 100% inhibition at highest doses.
Theraputic Index of FF
时间窗: 12 hours post-dose on Day 7, pre-dose PM dose on Day 6 to pre-dose PM dose Day 7
Therapeutic Index was calculated by ED20 for Cortisol Suppression 0-24 Hours Weighted Mean (nanomoles per liter\[nmol/L\]) divided by Dose at which 80% of the maximum effect is reached (ED80) for AMP PC20 for FF 25 mcg, FF 100 mcg, FF 200 mcg, FF 400 mcg, FF 800 mcg. Theraputic index has been presented. Only those participants with data available at the specified time points were analyzed. The timeframe mentioned is for AMP PC20 and Cortisol suppression respectively.
Theraputic Index of BUD
时间窗: 12 hours post-dose on Day 7, pre-dose PM dose on Day 6 to pre-dose PM dose Day 7

Theraputic index has been presented. The timeframe mentioned is for AMP PC20 and Cortisol suppression respectively.
Theraputic Index of FP
时间窗: 12 hours post-dose on Day 7, pre-dose PM dose on Day 6 to pre-dose PM dose Day 7
Therapeutic Index was calculated by Dose at which 20% of the maximum effect is reached (ED20) for Cortisol Suppression 0-24 Hours Weighted Mean (nanomoles per liter\[nmol/L\]) divided by ED80 for AMP PC20 for FP 50 mcg, FP 200 mcg, FP 500 mcg, FP 1000 mcg, FP 2000 mcg. Theraputic index has been presented. The timeframe mentioned is for AMP PC20 and Cortisol suppression respectively.
