A Study to Assess the Efficacy and Safety of Multiple Dose Levels of AZD7594 Administered Once Daily by Inhalation in Asthmatic Subjects

Completed · Phase 2 · Has a placebo group

Conditions studied: Asthma

In brief

This study will assess the efficacy and safety of multiple dose levels of AZD7594 administered once daily (QD) by inhalation in a 12-week treatment period on asthma subjects. The activity will be assessed by comparing AZD7594 to placebo. The comparison between active comparator (FF) and placebo will be used for bench marking. The efficacy is assessed by the evaluation of change in trough forced expiratory volume in 1 second (FEV1). The aim is to develop AZD7594 as a once daily inhaled non-steroidal selective GR modulator (SGRM), which may ultimately lead to better disease control of both chronic obstructive pulmonary disease (COPD) and asthma through improved efficacy and compliance. The overall rationale for developing a once daily AZD7594 in a dry powder inhaler (DPI) is to provide a safe and effective future treatment option for both asthma and COPD subjects.

You may qualify if…

Provision of informed consent prior to any study-specific procedures 2. Men and women 18 to 85 years of age, inclusive, with body mass index (BMI)≤35 3. Subjects need to be non-smokers or ex-smokers (have quit e cigarettes or other inhaled tobacco products ≥6 months before Visit 1) with a total smoking history of less than 10 pack-years (not applicable for e cigarettes) 4. Documented clinical diagnosis of asthma for ≥6 months before Visit 1 5. Subjects on stable medium to high dose ICS (equivalent of budesonide >400 μg/day) or low to medium dose ICS/LABA for at least 4 weeks prior to screening (Visit 1) (Appendix A, GINA, 2018) 6. Subjects must demonstrate reversibility to inhaled bronchodilators at Visit 2 (a ≥12% and ≥200 mL improvement in FEV1 after administration of a 4 puffs of salbutamol/albuterol) 7. Pre-bronchodilator FEV1 at Visit 3 between 40% and 90% predicted at either -45 or -15 minutes pre-dose 8. At Visit 3, subjects need to be symptomatic on low dose ICS as evidenced by combined daily asthma mean symptom score of >1 over the previous 7 days or SABA use on ≥3 of the last 7 days during the Run-in Period 9. Demonstrate the ability to use the study inhalation device properly 10. Subject able to perform acceptable pulmonary function testing for FEV1 according to American Thoracic Society/European Respiratory Society (ATS/ERS) acceptability criteria 11. Subject is willing and able to follow study procedures and restrictions. Women of child bearing potential (WOCBP) should be stable on their chosen method of highly effective birth control for a minimum of 3 months prior to Visit 1, and willing to use that for the entire duration of the study (from the time they sign the informed consent), and for 1 month after the last dose of IP 12. For optional inclusion in the Gx component of the study, subjects must provide separate informed consent for the genomic sampling and analysis Exclusion criteria
Known or suspected hypersensitivity to any of the IPs, including budesonide, or excipients, including lactose
Systemic steroid use within the 6 weeks before Visit 1
Concomitant chronic respiratory disease (including current sleep apnea)
History or clinical suspicion of any clinically relevant or active disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study, or any other safety concerns in the opinion of the Investigator
Use of prohibited medications that cannot be stopped during the entire period of the study (starting Visit 1).
Subjects with <80% eDiary compliance during Run in Period at Visit 3
ACQ-5 of ≥3 at Visit 1, Visit 2, or Visit 3
Daily rescue use of SABA ≥12 puffs for ≥3 consecutive days at any time during Run-in Period, before randomisation

Prolonged QT interval corrected using Fridericia's formula (QTcF) ≥450 msec based on ECG at Visit 1 or Visit 3; or family history of long QT syndrome
PR (PQ) interval prolongation (>240 msec), intermittent second or third degree atrial-ventricular (AV) block or AV dissociation at Visit 1 or Visit 3
Subjects with implantable cardiac defibrillator and subjects with sustained symptomatic ventricular and/or atrial tachyarrhythmia
Subjects with unstable angina pectoris or stable angina pectoris classified higher than Canadian Cardiovascular Society Class II, or a myocardial infarction or stroke within 6 months before Visit 1
