Study Details

Study Description

Brief Summary

Batefenterol inhalation powder is currently under development as a fixed-dose combination with fluticasone furoate (FF) for the treatment of Chronic Obstructive Pulmonary Disease (COPD).

The present study will administer batefenterol/FF (300/100 micrograms [mcg]) for the first time to subjects with COPD, to investigate the safety and tolerability of the combination compared with placebo, and to evaluate the pharmacokinetics and pharmacodynamics profiles of the individual components when administered in combination.

This is a Phase IIa, multicenter, randomized, placebo-controlled, double-blind, parallel group study. Subjects will be randomized (2:1) to one of the following double-blind treatment groups:

Batefenterol/FF 300/100 mcg inhalation powder once daily, or matching placebo inhalation powder once daily.

Subjects will self-administer the study treatments once daily (QD) in the morning for 42 days via a multi-dose dry powder inhaler (DPI) which contains two blister strips. Additionally, an inhaled short acting beta2-receptor agonist, albuterol will be provided from screening to the end of the treatment period for all subjects to use as needed to relieve COPD symptoms. At the end of the treatment period, subjects can resume conventional therapy.

The study will randomize approximately 60 subjects. The total duration of subject participation (from screening to follow-up) will be approximately 8 weeks.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Batefenterol + Fluticasone Furoate

Subjects will self-administer batefenterol/fluticasone furoate 300/100 micrograms inhalation powder once daily for 42 days. Albuterol will be provided from screening to Day 42, to use as needed for symptom relief.

Drug: Batefenterol + Fluticasone Furoate
Batefenterol and Fluticasone Furoate (FF) will be provided as a fixed-dose combination in a dry powder inhaler (DPI), for oral inhalation once every morning, for 42 days. The DPI will consist of 2 strips of 30 blisters each, containing 300 microgram (mcg) batefenterol per blister in one strip and 100 mcg FF per blister in another strip. Both drugs will be available in a micronized form, blended with lactose monohydrate.

Drug: Albuterol
Albuterol inhalation will be provided as an open-label rescue medication to use as needed, to relieve chronic obstructive pulmonary disease (COPD) symptoms.

Placebo Comparator: Placebo

Subjects will self-administer matching placebo inhalation powder once daily for 42 days. Albuterol will be provided from screening to Day 42, to use as needed for symptom relief.

Drug: Placebo
Placebo will be provided in a DPI, for oral inhalation once every morning, for 42 days. The DPI will consist of 2 matching strips of 30 blisters each, with each blister containing lactose monohydrate and no active pharmaceutical ingredient.

Drug: Albuterol
Albuterol inhalation will be provided as an open-label rescue medication to use as needed, to relieve chronic obstructive pulmonary disease (COPD) symptoms.

Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in 0 to 4 Hours Post-dose Weighted Mean Heart Rate at Day 42, Derived From Electrocardiograms (ECGs) [Baseline and Day 42]

    ECG measurements were taken in supine position after obtaining vital signs. Weighted mean was derived by calculating the area under the curve (AUC), and then dividing by the relevant time interval. Baseline was the pre-dose measurement on Day 1. Change from Baseline in 0 to 4 hours post-dose weighted mean heart rate was measured on Days 1, 28 and 42 and was analyzed using a mixed models repeated measures (MMRM) model. Intent-To-Treat (ITT) Population: all randomized participants who received at least one dose of study medication.

Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Type of subject: Outpatient.

  • Informed Consent: Capable of giving signed informed consent, which includes compliance with pre-specified requirements and restrictions.

  • Age and gender: Male and female subjects, 40 years of age or older at the time of signing the informed consent, are eligible to participate in the study.

Female subject: is eligible to participate if she is not pregnant (as confirmed by a negative urine human chorionic gonadotrophin (hCG) test), not lactating, and at least one of the following conditions applies:

  1. Non-reproductive potential defined as:

Pre-menopausal females with one of the following: documented tubal ligation; documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion; hysterectomy; documented bilateral oophorectomy Postmenopausal defined as 12 months of spontaneous amenorrhea. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.

  1. Reproductive potential and agrees to follow one of the options listed below 30 days prior to the first dose of study medication and until at least five terminal half-lives OR until any continuing pharmacologic effect has ended, whichever is longer after the last dose of study medication and completion of the follow-up visit. This list does not apply to females of reproductive potential with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long term and persistent basis:

Contraceptive subdermal implant that meets the standard operating procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label Oral Contraceptive, either combined or progestogen alone Injectable progestogen Contraceptive vaginal ring Percutaneous contraceptive patches Male partner sterilization with documentation of azoospermia prior to the female subject's entry into the study, and this male is the sole partner for that subject These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.

  • Chronic Obstructive Pulmonary Disease (COPD): An established clinical history of COPD in accordance with the definition by the American Thoracic Society/European Respiratory Society.

  • COPD Disease severity: A post-albuterol forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) ratio of =<0.70 and a post-albuterol FEV1 >=30 and =<80% of predicted normal values calculated using the European Respiratory Society Global Lung Function Initiative reference equations at Visit 1.

  • Smoking history: Current or former cigarette smokers with a history of cigarette smoking of >= 10 pack-years at Visit 1. Former smokers are defined as those who have stopped smoking for at least 6 months prior to Visit 1.

Number of pack years = (number of cigarettes per day / 20) x number of years smoked (for example, 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years both equal 10 pack-years).

Note: Pipe and cigar use cannot be used to calculate pack-year history.

Exclusion Criteria:

  • Other Respiratory Disorders: Known alpha-1 antitrypsin deficiency, active lung infections (such as tuberculosis), and lung cancer are absolute exclusionary conditions. Other excluded conditions include and not limited to clinically significant bronchiectasis, pulmonary hypertension unrelated to COPD, sarcoidosis, or interstitial lung disease. Or a subject who, in the opinion of the investigator, has any other significant respiratory conditions in addition to COPD

  • Use of long-term oxygen therapy (LTOT): Oxygen therapy prescribed for greater than 12 hours a day. As-needed oxygen use (that is, =<12 hours per day) is not exclusionary.

  • Nebulized Therapy: Regular use (prescribed for use every day, not for as-needed use) of short-acting bronchodilators (for example, albuterol) via nebulized therapy.
