Outcome Measures

Primary Outcomes (1)

Eligibility Criteria

Age18 Years - 45 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age
  • Male and female participant must be 18 to 45 years of age inclusive, at the time of signing the informed consent form (ICF).
  • Type of Participant and Disease Characteristics
  • Participants who have a documented history of physician-diagnosed asthma
  • ≥ 12 months prior to Visit 1, according to GINA guidelines (GINA 2022).
  • Participants who are well controlled or partially controlled on their current treatment for asthma, including, low-dose ICS daily or low-dose ICS/formoterol as needed (not approved in the US), or SABA as needed, or low-dose ICS whenever SABA as needed is used (low-dose ICS as defined by GINA 2022 in Table 4), for 4 weeks prior to screening.
  • ACQ-5 total score \< 1.5 at Visit 1.
  • A pre-bronchodilator FEV1 \> 60% predicted normal value at Visit 1.
  • Demonstrate acceptable MDI administration technique.
  • Sex and Contraceptive/Barrier Requirements
  • Females must be not of childbearing potential, or should be using a form of highly effective birth control as defined below:
  • Female participants Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women included in this study will be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatment and follicle-stimulating hormone levels in the postmenopausal range.
  • Female participants of childbearing potential must use one highly effective form of birth control. A highly effective method of contraception is defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly. At enrolment, women of childbearing potential who are sexually active with a non-sterilized male partner should be stable on their chosen method of highly effective birth control, as defined below, and willing to remain on the birth control until at least 14 days after last dose of study intervention. Cessation of contraception after this point should be discussed with a responsible physician.
  • Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together. All women of childbearing potential must have a negative serum pregnancy test result at Visit 1.
  • Highly effective birth control methods are listed below:
  • +9 more criteria

You may not qualify if:

  • Medical Conditions
  • Life-threatening asthma defined as a history of significant asthma episode(s) requiring intubation associated with hypercapnia, respiratory arrest, hypoxic seizures, or asthma related syncopal episode(s).
  • Current smokers, former smokers with \> 10 pack-years history, or former smokers who stopped smoking \< 6 months prior to Visit 1 (including all forms of tobacco, e-cigarettes or other vaping devices, and marijuana).
  • Historical or current evidence of a clinically significant disease including, but not limited to: cardiovascular, hepatic, renal, hematological, neurological, endocrine, gastrointestinal, or pulmonary (e.g., active tuberculosis, bronchiectasis, pulmonary eosinophilic syndromes, COPD, and uncontrolled severe asthma). Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the participant at risk through participation, or that could affect the safety/tolerability analysis.
  • Any respiratory infection or asthma exacerbation treated with systemic corticosteroids and/or additional ICS treatment in the 8 weeks prior to Visit 1 and throughout the screening period.
  • Hospitalization for asthma within 1 year prior to Visit 1.
  • Admission to intensive care unit or mechanical ventilation due to asthma exacerbation.
  • Known history of drug or alcohol abuse within 12 months of Visit 1.
  • Prior/Concomitant Therapy
  • Do not meet the stable dosing period prior to Visit 1 (see Table 5) or unable to abstain from protocol-defined prohibited medications during screening and treatment periods (see Table 6 and Table 7).
  • Receipt of COVID-19 vaccine (regardless of vaccine delivery platform, e.g., vector, lipid nanoparticle) ≤ 7 days prior to Visit 1 (from last vaccination or booster dose).
  • Prior/Concurrent Clinical Study Experience 10 Participation in another clinical study with an investigational product administered within 30 days or 5 half-lives (whichever is longer). 11 Participants with a known hypersensitivity to HFO or HFA or any of the excipients of the product. 12 Previously randomized into a study with an HFO-containing MDI.
  • Diagnostic Assessments 13 Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, urinalysis, vital signs, or electrocardiogram (ECG), which in the opinion of the investigator, may put the participant at risk because of his/her participation in the study. Note: Participants with ECG QT interval corrected for heart rate using Fridericia's formula (QTcF) \> 480 msec will be excluded. Participants with high degree atrioventricular block II or III, or with sinus node dysfunction with clinically significant pauses who are not treated with pacemaker will also be excluded.
  • Previous enrolment or randomisation in the present study. 17 For women only - currently pregnant (confirmed with positive pregnancy test), breast feeding, or planned pregnancy during the study or women of childbearing potential not using acceptable contraception measures. 18 Study investigators, sub-investigators, coordinators, and their employees or immediate family members.
