Brief Summary

This study will evaluate the efficacy and safety data of AZD8871 in patients with moderate to severe chronic obstructive pulmonary disease (COPD). This study will determine the 24-hour efficacy (lung function) profile of AZD8871 600 μg relative to placebo dry powder inhaler (DPI) based on trough forced expiratory volume in 1 second (FEV1) following repeated dosing (2 weeks). Anoro® Ellipta® (umeclidinium/vilanterol) once daily is included as an active control. This study aims at providing a novel approach to the treatment of COPD with greater efficacy than single-mechanism bronchodilators, equivalent to long-acting muscarinic antagonist (LAMA) and long-acting β2-agonist (LABA) administered as free- or fixed-dose combination therapies, with an equivalent or superior safety and tolerability profile.

Detailed Description

This randomized, double-blind, placebo and active-controlled crossover study will be conducted at 5 sites in Germany and the United Kingdom (UK). Approximately 180 patients will be screened in order to randomize 72 patients into the study. Based on previous studies estimate, it is anticipated that 54 patients will be evaluable (study completers) assuming an approximate 25% dropout rate. A subset of 36 patients, who will have specifically consented for pharmacokinetics (PK), will undergo PK assessments. The study will consist of -

• A Screening period: Will last up to 28 days and consists of 2 Screening visits (Visit 1 and Visit 2) and a run-in period (between a minimum of 14 and a maximum of 28 days; from Visit 2 to Visit 3).
• Three treatment periods (Visit 3; 14 days each; each separated by a wash-out period of 42 to 49 days) and
• A Follow-up Visit: 42 days (up to 49 days) after last investigational product (IP) administration.

Patients will be requested to stop their usual COPD therapy after signing the informed consent form (ICF) at Visit 1 and will be maintained on a mono-component inhaled corticosteroid (ICS) therapy, if required. Patients that were taking any LAMA will be maintained with ipratropium (34 µg × 2 puffs 4 times per day) between Visit 1 and Visit 2. In addition, salbutamol 100 µg will be provided as rescue medication during the study as needed (rescue medication has to be discontinued 6 hours before any pulmonary function test). Visit 1 and Visit 2 could be performed on the same day if no wash-out of prior medication is required and the patient visits the site in fasting condition. In case any wash-out of prior medication is required, then Visit 2 will be performed after the wash-out is complete. If reversibility criteria and forced expiratory volume in 1 second (FEV1) predicted values are fulfilled according to inclusion criteria, the patient will be started on run-in period to assess clinical stability. If reversibility criteria or FEV1 predicted values are not met, pulmonary function tests could be rescheduled at the latest, up to Day 14. During the run in period, all patients will receive ipratropium 34 µg × 2 puffs 4 times per day (must be discontinued 8 hours prior to previous any pulmonary function test). A paper diary will be used to collect adverse events (AEs) and concomitant medication during run-in and wash-out periods.

Eligible patients will be randomized in 1:1:1:1:1:1 ratio to 1 of 6 treatment sequences and will receive orally 1 of the following 3 treatments sequence in the form of inhalation powder using DPI :

• AZD8871 600 µg once daily (double-blind).
• Anoro® Ellipta® (55 µg umeclidinium [UMEC]/ 22 µg vilanterol [VI]) once daily (double-blind).
• Placebo (double-blind). Study treatment administration during all the visits at the sites (Day 1, Day 2, Day 8, and Day 14 of each treatment period) will be supervised by study personnel.

During the treatment period Visits, safety and tolerability assessments and pulmonary function measurements will be taken pre-dose and up to 24 hours (Day 1) and up to 4 hours (Day 8) post-dose, respectively.

At Visits 3 to 11, a subset of 36 patients will undergo PK assessments. Blood samples will be collected pre-dose and up to 24 hours post dose.

In follow-up visit, AEs, safety laboratory, electrocardiogram (ECG), vital signs and physical examination will be assessed.

The study includes 12 visits and the entire study period is scheduled to take from a minimum of 6.5 months (182 days) to a maximum of 7.5 months (217 days) for each individual patient. The estimated study duration is 12 months.

3. Patient with an established clinical history of moderate to severe COPD for more than 1 year at Screening, according to the GOLD COPD guidelines.

4. Patient who is a current or former smoker (defined as one who has stopped smoking for at least 6 months prior to Screening) with a history of ≥10 pack-years of cigarette smoking [Number of pack-years=(number of cigarettes per day/20)* number of years smoked (eg, 1 pack-year=20 cigarettes smoked per day for 1 year)].

5. Patient with post-bronchodilator FEV1/forced vital capacity (FVC) ratio <70% based on the value reached after inhalation of salbutamol (400 µg) at Visit 2. If criterion is not met, the test can be repeated at the latest, up to Day -14.

6. Patient with post-bronchodilator FEV1 that must be ≥40% and <80% predicted normal value at Visit 2. If criterion is not met, the test can be repeated at the latest, up to Day -14.

7. Patient is willing and, in the opinion of the Investigator, able to change current COPD therapy as required by the protocol and willing to use ipratropium following the approved dosage and regimen (during run-in and wash-out periods) with or without ICS for maintenance therapy of COPD and rescue medication salbutamol (as needed) from Visit 1 to Visit 11.

8. Patient must be able to read, speak and understand local language, and be willing to remain at the study centre as required per-protocol to complete all visit assessments.

9. Body mass index (BMI) <40 kg/m2 at the time of Screening.

10. Female patients must be of non-childbearing potential defined as:

• Permanently or surgically sterilised, including hysterectomy and/or bilateral oophorectomy and/or bilateral salpingectomy.
• Post-menopausal; aged <50 years and amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and with luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the post menopausal range of the local laboratory.
• Post-menopausal; aged ≥50 years and amenorrhoeic for 12 months or more, following cessation of all exogenous hormonal treatments.

11. Male patients should use a condom and spermicide to prevent pregnancy and drug exposure of a partner, regardless of the gender or childbearing potential of the partner from the day of the first administration of the IP until 3 months after the last administration of the IP. In addition to a condom with spermicide, a second highly effective method of contraception (oral, intravaginal or transdermal hormonal contraceptives, intrauterine device, intrauterine hormone-releasing system, or sexual abstinence until 3 months after the last administration of the IP) should be used with female partners of childbearing potential. Double barrier methods (a combination of male condom with either a cap, diaphragm or sponge with spermicide) are not considered to be highly effective methods of contraception. Male patients with a pregnant partner should use a condom and spermicide.

Exclusion Criteria

1. Patient has significant diseases other than COPD, (ie, clinically relevant disease or condition or an abnormality in prior ECGs, medical history or physical examinations) which, in the opinion of the Investigator, may put the patient at risk because of participation in the study or may influence either the results of the study or the patient's ability to participate in the study.

2. Patient has alpha-1 antitrypsin deficiency as the cause of COPD.

3. Patient has other active pulmonary disease such as predominant asthma, active tuberculosis, lung cancer, bronchiectasis, sarcoidosis, idiopathic interstitial pulmonary fibrosis, primary pulmonary hypertension, or uncontrolled sleep apnoea. Allergic rhinitis is not exclusionary.

4. Lung surgery for volume reduction or lung transplantation: Patient has undergone lung volume reduction surgery, lobectomy, or bronchoscopic lung volume reduction (endobronchial blockers, airway bypass, endobronchial valves, thermal vapour ablation, biological sealants, massive pulmonary embolism and airway implants) within 1 year of Screening (Visit 1).

5. Patient is using nocturnal positive pressure (eg, continuous positive airway pressure or bi level positive airway pressure). Patient is using any non-invasive positive pressure ventilation device. Note: A patient using continuous positive airway pressure or bi level positive airway pressure for Sleep Apnoea Syndrome is allowed in the study.

Note: Patient participation in observational studies (ie, studies that do not require change to medication or an additional intervention) is not exclusionary.

26. Previous participation or prior screen failure in the present study.

27. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).

28. Patient has changed their smoking status (ie, restarted or stopped smoking) or initiation of a smoking cessation program within 6 weeks of Screening.

29. Patient has participated in the acute phase of a pulmonary rehabilitation program within 4 weeks prior to Screening or who will enter the acute phase of a pulmonary rehabilitation program during the study. A patient in the maintenance phase of a pulmonary rehabilitation program is not to be excluded.
