About this study
Official title: A Phase I, Single Centre, Randomised, Single Blind, Placebo-Controlled Study to Investigate the Safety, Tolerability and Pharmacokinetics of Multiple Ascending Doses of Inhaled AZD8871 in Healthy Male Subjects
AZD8871 is a new chemical entity possessing long-acting effect in a single molecule which presents a novel treatment approach to chronic obstructive pulmonary disease [COPD] and potentially also asthma (in combination with an inhaled corticosteroid [ICS]). The therapeutic goal for AZD8871 is a treatment with greater efficacy than single mechanism bronchodilators, with an equivalent or superior safety and tolerability profile. The primary purpose of this study is to check the safety and tolerability of AZD8871 at steady state. A multiple ascending dose (MAD) design has been selected for this study following the first time in man (FTIM), single ascending dose (SAD) study. Three dose levels will be tested in an ascending manner. The first dose to be administered will be 300 μg and the 2 subsequent doses will be decided based on safety, tolerability and pharmacokinetic (PK) data generated in the previous dose. The aim of this study is to also enable further investigations in healthy subjects to evaluate and develop AZD8871 as a dual action bronchodilator with an acceptable side-effect profile compared to other inhaled bronchodilators on the market as a treatment for COPD and asthma.
Read the detailed description
AZD8871 is a new chemical entity possessing long-acting dualpharmacology (muscarinic receptor antagonist and β2 adrenoceptor agonist [MABA]) in a single molecule. This type of agent presents a novel approach to the treatment of chronic obstructive pulmonary disease [COPD] and potentially also asthma (in combination with an inhaled corticosteroid [ICS]). AZD8871 is being developed for inhalation, formulated with alpha-lactose monohydrate and delivered by dry powder inhaler (DPI) that allows delivery of a single dose of the study drug. By combining this bi-functional activity, the therapeutic goal for AZD8871 is a treatment with greater efficacy than single mechanism bronchodilators, equivalent to long-acting β2-agonist (LABA) and long-acting muscarinic antagonist (LAMA) administered as free- or fixed-dose combination (FDC) therapies, with an equivalent or superior safety and tolerability profile. The current study will start with a single dose of 300 μg AZD8871 or placebo administered to 8 healthy subjects following a 3-day washout period, dosing will then continue for a further 12 days. Following the 1st cohort, 2 further cohorts of 8 subjects each will be administered multiple ascending doses (MAD) of AZD8871 in the same manner as Cohort 1. A MAD design has been selected for this study following the first time in man (FTIM), single ascending dose (SAD) study. Each subject will only be dosed in 1 cohort. The study design allows a gradual escalation of dose (Cohorts 2 and 3) with intensive safety monitoring to ensure the safety of the subjects. In Cohort 1, subjects will receive a single dose of AZD8871 300 μg or placebo on Day 1, followed by once daily dosing on Days 5 to 16. The dosing schedule of all cohorts will be single dose of IMP (active or placebo) on Day 1, followed by once daily dosing on Days 5 to 16. Within 5 to 7 days of discharge from the unit, there will be a Follow-up Visit. Dosing of Cohorts 2 and 3 will be preceded by a safety review committee (SRC) meeting, which will decide the exact dose to be given in the subsequent cohort. The dose escalation between cohorts will not exceed a multiple of 3 and the AZD8871 dose level in the study, for any cohort, will not exceed 2100 μg per day. The planned dose for Cohort 2 is either 600 or 900 μg, however the SRC may decide a different dose level. A minimum of 5 subjects on active treatment need to complete dosing per cohort in order to proceed to the next dose level. The aim of this study is to also enable further investigations in healthy subjects to evaluate and develop AZD8871 as a dual action bronchodilator with an acceptable side-effect profile compared to other inhaled bronchodilators on the market as a treatment for COPD and asthma.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With ≥1 Treatment Emergent Adverse Event in Any Category.
Recording treatment emergent adverse events (TEAE).
A TEAE was defined as an AE with onset (start date/time) after the first dose of investigational medicinal product. An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal results of an investigation (e.g., laboratory findings, ECG).
Measured: Change from baseline up to Days 25-27
Number of Participants With Clinically Relevant Abnormalities in Recording of Physical Examination.
A full physical examination included the examination of the following: general appearance, eyes, ears, nose, throat, chest/respiratory, heart/cardiovascular, gastrointestinal/liver, musculoskeletal/extremities, dermatological/skin, thyroid/neck, lymph nodes, neurological/psychiatric.
A brief physical examination included assessment of the following: skin, lungs, cardiovascular system and abdomen (liver and spleen).
A complete physical examination was performed at the Screening Visit. Any abnormal finding assessed as the investigator as clinically relevant was reported as an adverse event.
Measured: Change from baseline up to Days 25-27
Number of Participants With Clinically Relevant Abnormalities in Vital Signs (Pulse, Blood Pressure and Body Temperature).
Systolic and diastolic BP (SBP/DBP) (in mmHg) measured after at least 10 minutes (could be reduced to 5 minutes at collection time points within the 1st hour after dosing) resting, and also before taking any blood sample and conducting any spirometry. Measurements were carried out with subject in the supine position and preferably always on the same arm.
Subject's oral body temperature was measured at each vital signs collection.

In Cohort 1, subjects will receive a single dose of AZD8871 300 μg or placebo on Day 1, followed by once daily dosing on Days 5 to 16. The dosing schedule of all cohorts will be single dose of IMP (active or placebo) on Day 1, followed by once daily dosing on Days 5 to 16. Within 5 to 7 days of discharge from the unit, there will be a Follow-up Visit. Dosing of Cohorts 2 and 3 will be preceded by a safety review committee (SRC) meeting, which will decide the exact dose to be given in the subsequent cohort. The dose escalation between cohorts will not exceed a multiple of 3 and the AZD8871 dose level in the study, for any cohort, will not exceed 2100 μg per day. The planned dose for Cohort 2 is either 600 or 900 μg, however the SRC may decide a different dose level. A minimum of 5 subjects on active treatment need to complete dosing per cohort in order to proceed to the next dose level. The aim of this study is to also enable further investigations in healthy subjects to evaluate and develop AZD8871 as a dual action bronchodilator with an acceptable side-effect profile compared to other inhaled bronchodilators on the market as a treatment for COPD and asthma.

Primary outcome
Number of Participants With ≥1 Treatment Emergent Adverse Event in Any Category.
Time frame: Change from baseline up to Days 25-27
Recording treatment emergent adverse events (TEAE). A TEAE was defined as an AE with onset (start date/time) after the first dose of investigational medicinal product. An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal results of an investigation (e.g., laboratory findings, ECG).
Number of Participants With Clinically Relevant Abnormalities in Recording of Physical Examination.
Time frame: Change from baseline up to Days 25-27
A full physical examination included the examination of the following: general appearance, eyes, ears, nose, throat, chest/respiratory, heart/cardiovascular, gastrointestinal/liver, musculoskeletal/extremities, dermatological/skin, thyroid/neck, lymph nodes, neurological/psychiatric. A brief physical examination included assessment of the following: skin, lungs, cardiovascular system and abdomen (liver and spleen). A complete physical examination was performed at the Screening Visit. Any abnormal finding assessed as the investigator as clinically relevant was reported as an adverse event.
