Conditions: Pulmonary Disease, Chronic Obstructive
Keywords: FEV1 DPI ICS/LABA UMEC COPD
Sponsor: GlaxoSmithKline
Start date: 2014-09-30; Completion date: 2015-03-24
Enrollment: 236 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
This is a multicenter, randomized, double-blind, parallel-group study to evaluate the efficacy and safety of the addition of UMEC (62.5 microgram\[mcg\]) when administered once-daily via dry powder inhaler (DPI) to Inhaled corticosteroid/ Long-acting beta2-agonist (ICS/LABA) twice-daily compared with placebo via DPI added to the ICS/LABA therapy over a treatment period of 12 weeks in subjects with COPD. This study is designed to investigate the addition of UMEC to ICS/LABA combinations at approved doses and frequencies for the treatment of COPD including SERETIDE™ 500/50 mcg twice daily, Fluticasone Propionate/Salmeterol Combination (FSC) 500/50 twice daily generic products such as AIRFLUSAL FORSPIRO inhaler 500/50 mcg twice daily or ROLENIUM ELPENHALER inhaler 500/50 mcg twice daily and SYMBICORT TURBUHALER inhaler at doses of 200/6 mcg twice daily and 400/12 mcg twice daily, over 12 weeks in subjects with COPD. Albuterol/salbutamol metered-dose-inhaler (MDI) or nebules will be issued throughout the study for use as-needed (prn).

Subjects who meet the eligibility criteria will be randomly assigned to one of the following blinded study treatment regimens in equal proportion (1:1): UMEC 62.5 mcg once-daily and Placebo once-daily. Approximately 230 subjects (115 subjects per treatment) will be randomized in order to complete at least 206 evaluable subjects. The total duration of the study will be approximately 14 weeks for each subject.

UMEC is a Long-acting Muscarinic Antagonist (LAMA) currently under development as a monotherapy, as a combination product with a LABA, vilanterol (VI), for the treatment of COPD, and as a combination product with an ICS, fluticasone furoate (FF), for the treatment of asthma. The UMEC/VI combination 62.5/25 .mcg once-daily has been approved in the United States (U.S.) and Canada for COPD under the trade name ANORO™ ELLIPTA™ and is under regulatory review in other countries.

Detailed description:

Arms: arm 1: Participants will self-administer blinded UMEC (62.5 mcg) each morning (once daily) as one inhalation from the double-blind DPI over a treatment period of 12 weeks. Participants will receive open labeled ICS/LABA medication through out duration of the treatment period as background treatment. arm 2: Participants will self-administer blinded placebo each morning (once daily) as one inhalation from the double-blind DPI over a treatment period of 12 weeks. Participants will receive open labeled ICS/LABA medication through out duration of the treatment period as background treatment
Interventions: intervention 1: UMEC DPI intervention 2: Placebo DPI intervention 3: ICS/LABA medication intervention 4: Albuterol/salbutamol Metered Dose Inhaler (MDI)
Intervention descriptions: intervention 1: The UMEC DPI will contain one blister strip which will have 30 blisters of UMEC as dry powder blended with lactose and magnesium stearate, with no companion strip. Each actuation of the DPI will deliver the contents of one blister from each strip simultaneously. intervention 2: The matching placebo DPI, identical in appearance to the inhaler containing active study medication, will have two blister strips, each containing 30 blisters of lactose and magnesium stearate. intervention 3: Participants will use ICS/LABA combinations that are approved for the treatment of COPD at approved doses and frequency including SERETIDE 500/50mcg twice daily, FSC 500/50 mcg twice daily generic products such as AIRFLUSAL FORSPIRO inhaler 500/50mcg twice daily or ROLENIUM ELPENHALER inhaler 500/50mcg twice daily and SYMBICORT TURBUHALER inhaler at doses of 200/6mcg twice daily and 400/12mcg twice daily. The ICS/LABA will be sourced from local commercial stock while on the study intervention 4: Albuterol/salbutamol MDI or nebules will be issued throughout the study as rescue medication, for use as-needed. Albuterol/salbutamol will be sourced from local commercial stock or provided centrally from GlaxoSmithKline.
