Phase 2a, AMP Challenge, Dose Escalation Study to Assess the Dose Response for Topical Efficacy and Systemic Activity in Asthmatic Subjects

NCT ID: NCT02991859

Last Updated: 2020-07-31

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 56 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-02-09
• Study Completion Date: 2018-12-20

Brief Summary

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.

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. A positive serology at screening. - Allergies: History of severe milk protein allergy Drug Allergy defined as any adverse reaction including immediate or delayed hypersensitivity to intranasal, inhaled, or systemic corticosteroid therapy. 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).
