A 24-Week Efficacy and Safety Study to Assess Budesonide and Formoterol Fumarate Metered Dose Inhaler in Adult and Adolescent Participants with Inadequately Controlled Asthma (VATHOS) - VATHOS

Exclusion Criteria

• 1. Life-threatening asthma as defined as a history of significant asthma episode(s) requiring intubation associated with hypercapnia, respiratory arrest, hypoxic seizures, or asthma related syncopal episode(s).
• 2. 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.
• 3. Hospitalization for asthma within 8 weeks of Visit 1.
• 4. Historical or current evidence of a clinically significant disease including, but not limited to: cardiovascular, hepatic, renal, hematological, neurological, endocrine, gastrointestinal, or pulmonary (eg, active tuberculosis, bronchiectasis, pulmonary eosinophilic syndromes, and COPD). 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 efficacy or safety analysis.
• 5. Known history of drug or alcohol abuse within 12 months of Visit 1.
• 6. Unresectable cancer that has not been in complete remission for at least 5 years prior to Visit 1.
• 7. Participation in another clinical study with a study intervention administered in the last 30 days or 5 half-lives, whichever is longer. Any other study intervention that is not identified in this protocol is prohibited for use during study duration.
• 8. Previous or current randomization into studies within the AEROSPHERE program including KALOS, LOGOS, VATHOS, LITHOS, or any glycopyrronium studies (PT001).
• 9. Use of a nebulizer or a home nebulizer for receiving asthma medications.
• 10. Do not meet the stable dosing period prior to Visit 1 or unable to abstain from protocol-defined prohibited medications during Screening and Treatment Periods.
• 11. Receipt of COVID-19 vaccine (regardless of vaccine delivery platform, eg, vector, lipid nanoparticle) < 7 days prior to Visit 1 (from last vaccination or booster dose).
• 12. Participants with known hypersensitivity to beta2-agonists, corticosteroids, or any component of the MDI.
• 13. Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, vital signs, or ECG, which in the opinion of the Investigator, may put the participant at risk because of his/her participation in the study.
• 14. 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).
• 15. Planned hospitalization during the study.
• 16. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
• 17. Study Investigators, sub-Investigators, coordinators, and their employees or immediate family members.
• 18. Judgment by the Investigator that the participant is unlikely to comply with study procedures, restrictions, and requirements.
• 19. For women only – currently pregnant (confirmed with positive highly sensitive urine pregnancy test), breast-feeding, or planned pregnancy during the study or not using acceptable contraception measures, as judged by the Investigator.
