A Study to Assess the Pharmacokinetics (PK), Pharmacodynamics (PD) and Safety of 2-Week Treatment With Inhaled AZD7594 in Adolescents (12 to 17 Years) With Asthma

Completed · Phase 1

Conditions studied: Asthma

In brief

This is an open-label, multi-centre, Phase I study to assess the PK, PD and safety of 2 week treatment with inhaled AZD7594 in adolescent patients with asthma. The study is planned to be conducted at 4-10 study sites in the United States. The study intends to include 24 patients (12 to 17-year-old patients). For each patient, the duration of participation in the study will be approximately 5 to 7 weeks (37 to 52 days).

You may qualify if…

Provision of signed and dated informed consent form (ICF) prior to any study-specific procedures from patient's parents/legal guardians is required and signed and dated informed assent from the patient.
Patient must be 12 to 17 years of age inclusive, at the time of signing the ICF/assent.
A minimum of 6-month documented history of asthma treated (daily or intermittently) for at least 3 months before screening (Visit 1) with either low dose inhaled corticosteroid (ICS) monotherapy or leukotriene receptor antagonist (LTRA) monotherapy.
Pre-bronchodilator FEV1 ≥70% of the predicted normal value at screening (Visit 1).
An ACQ-5 score <1.5 at screening (Visit 1).
Be non-smoker or ex-smoker who has stopped smoking (or using other nicotine products) for >6 months prior to screening (Visit 1).
Body mass index (BMI) above the 5th percentile for the patient's age and gender and a minimum weight of 30 kg at screening (Visit 1).
Male or female
Negative pregnancy test (urine or serum) for post-menarcheal female patients at screening (Visit 1).
Post-menarcheal female patients must be willing to use a highly effective method of contraception which results in a low failure rate (ie, less than 1% per year). Sexual abstinence will be accepted as an effective method of contraception, provided a discussion occurred between the subject and investigator to confirm this lifestyle.
After the washout period, patients are eligible to enter the treatment period only if all of the following inclusion criteria apply:
Negative pregnancy test (urine or serum) for post-menarcheal female patients at baseline (Visit 4).
FEV1 increase of at least 12% and 200 mL from baseline 15 to 30 minutes after 400 μg salbutamol (or albuterol equivalent of 360 µg) documented in the patient's medical history within 6 months of Visit 1, or confirmed at Visit 1 or Visit 2. In 12 to 14-year-old patients (who are likely to have a smaller forced vital capacity), positive reversibility testing could be based solely on the relative post bronchodilator response (at least 12%).

You may not qualify if…

Patients are eligible to enter the washout period if none of the following exclusion criteria apply:
Medical conditions
Any clinically significant disease or disorder (eg, cardiovascular, pulmonary other than asthma, gastrointestinal, liver, renal, neurological, musculoskeletal including bone fractures, endocrine including adrenal insufficiency, metabolic, malignant, psychiatric, major physical impairment, severe obesity including weight-related health problems) which, in the opinion of the Investigator, may either put the patient at risk because of participation in the study, or influence the result of the study, or the patient's ability to participate in the study.
Any clinically relevant abnormal findings in physical examination, clinical chemistry, haematology, urinalysis, vital signs, at screening (Visit 1), which, in the opinion of the Investigator, may put the patient at risk because of his/her participation in the study.
Prolonged QT interval corrected using Fridericia's formula (QTcF) ≥440 msec based on ECG at screening (Visit 1) or pre-dose at Visit 4, or family history of long QT syndrome.
Prolonged PR interval (>180 msec for ≤16-year-old patients and >200 msec for >16 year old patients) at screening (Visit 1) or pre-dose at Visit 4.
Heart rate <50 beats per minute (bpm) or >110 bpm.
History of or current alcohol or drug abuse (including marijuana), as judged by the Investigator.
Patients who are positive for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody or human immunodeficiency virus (HIV) at screening (Visit 1).
Hospitalisation due to asthma exacerbation or asthma exacerbation within 1 month prior to screening (Visit 1).
Lower respiratory tract infection within 1 month prior to screening (Visit 1).
Prior/concomitant therapy
Patient who, in the opinion of the Investigator, is unable to abstain from protocol-defined prohibited medications during the study.
Prior/concurrent clinical study experience
Participation in another clinical study with an investigational drug administered in the last 3 months before Visit 1, or participation in a method development study (no drug) 1 month prior to Visit 1.
Note: Participation is identified as the completion of a treatment related visit.
A definite or suspected personal history of intolerance or hypersensitivity to drugs and/or their excipients, judged to be clinically relevant by the Investigator.
Other exclusions
Inability to perform the required spirometry assessments, to use the AZD7594 inhaler or the short-acting beta agonist (SABA) inhaler, or to undergo blood sampling.
Parent/legal guardian involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
Judgement by the Investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.
Previous enrolment in the present study.
For post-menarcheal female patients only - currently pregnant, breastfeeding, or planning to become pregnant during the study.
After the washout period, patients are eligible to enter the treatment period if none of the following exclusion criteria apply:
An ACQ-5 score ≥3 at Visit 4.
