Efficacy, Pharmacokinetics (PK), Safety and Tolerability Study of Inhaled AZD8871

• Status: Completed
• Trial end date: 2017-08-18
• Target enrollment: 0
• Participant gender: All

Summary

This is a study to evaluate the effects of AZD8871 in patients with COPD. Adult male or female patients with moderate to severe COPD, who agree to be in this study, will receive 3 treatments, i.e. 2 different doses of AZD8871 and placebo (dummy medication containing no drug) at once a day for 2 weeks, in a random order. To make the comparison between AZD8871 and placebo as fair as possible, this study is "double blinded." This means that neither patient nor the study doctor will know in which order the 3 treatments will be given. This study will include patients who are between 40 and 80 years of age. In total there will be 42 patients participating in this study at two study centers in the United Kingdom and Germany. The study will have a total of 12 visits for each patient spanning for a period of 4 to 6 months. The study is anticipated to run for approximately 8 months and should not exceed 10 months.

• Phase: Phase 2

• 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.

3. Male patient 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 investigational product (IP) until 3 months after the last administration of the IP.

4. COPD Diagnosis: Patient with an established clinical history of COPD for more than 1 year at Screening, according to the Global Initiative for Chronic Obstructive Lung Disease 2016 COPD guidelines.

5. Tobacco Use: Patient is a current or former smoker with a history of ≥10 pack-years of cigarette smoking. A former smoker is defined as one who has stopped smoking for at least 6 months prior to Screening.

6. Patient with post-bronchodilator FEV1/FVC (Forced vital capacity) 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.

7. Patient with post-bronchodilator FEV1 that must be ≥40% and <80% predicted normal value and must also be >750 mL at Visit 2. If criterion is not met, the test can be repeated at the latest, up to Day 14.

8. Patient who fulfils reversibility criteria to salbutamol at Visit 2. Reversibility is defined as ≥12% and ≥200 mL increase in FEV1 after inhalation of 4 puffs of salbutamol. (400 µg). If criterion is not met, the test can be repeated at the latest, up to Day 14.

9. 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 Four times a day (if needed, during run-in and wash-out periods) with or without Inhaled corticosteroid for maintenance therapy of COPD and as needed rescue salbutamol from Visit 1 up Visit 11.

10. Patient is free from any clinically active disease other than COPD that may impact study outcome, as determined by medical history, physical examination, laboratory testing, and 12-lead ECG findings, at Screening.

11. Patient is willing to remain at the study centre as required per protocol to complete all visit assessments.

12. Patient with body mass index (BMI) <40 kg/m2 at the time of screening.

Exclusion Criteria:

1. Patient previously enrolled in the present study.

2. Patient has significant diseases other than COPD, ie, disease or condition or an abnormality in laboratory, ECG, medical history or physical examination 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'spatient's ability to participate in the study.

3. Childbearing potential female, pregnant or lactating.

4. Patient who, in the opinion of the Investigator, has a current diagnosis of asthma.

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

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

7.
