New asthma inhaler faces off against standard treatment in major trial

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 12 and ≤ 65 years at Screening. * History of recurrent asthma symptoms (cough, wheezing, shortness of breath, chest tightness). * Previous medical diagnosis of asthma (confirmed by records, prescriptions, or participant report). * Documented reversible airway obstruction by spirometry: FEV₁ increase ≥ 200 mL and ≥ 12% post-bronchodilator (at screening or prior report). * Moderate asthma (GINA step 3) for ≥ 6 months, clinically stable and controlled with LABA + low-dose inhaled corticosteroid for ≥ 90 days. * ACQ-7 score ≤ 0.75 at Screening. * At Randomization: ACQ-7 score ≤ 0.75 and ≥ 70% adherence during run-in. Exclusion Criteria: * Moderate/severe asthma exacerbation within 90 days prior to screening. * Other pulmonary disease (including predominant COPD). * Symptomatic acute or chronic respiratory infection. * BMI ≥ 40 kg/m². * Use of LAMA within 6 months prior to screening. * Oral or depot corticosteroids within 30 days prior to screening. * Biologic therapy for asthma, allergic rhinitis, or urticaria within 12 months prior to screening. * Systemic vasoconstrictors within 7 days prior to screening. * Known hypersensitivity to formoterol, fluticasone, budesonide, or any component of study drugs. * Active pulmonary tuberculosis or fungal airway infection. * History or presence of ischemic heart disease, severe arrhythmias, cardiac decompensation, idiopathic subvalvular aortic stenosis, severe hypertension, aneurysm, pheochromocytoma, hypertrophic obstructive cardiomyopathy, thyrotoxicosis, QTc \> 450 ms. * History of hyperthyroidism or uncontrolled diabetes mellitus. * Severe or uncontrolled disease at investigator's discretion. * Pregnancy or breastfeeding; women of childbearing potential not using effective contraception. * Participation in another clinical trial within 12 months unless direct benefit expected. * Any condition making participant unsuitable for study per investigator. * At Randomization: asthma exacerbation during run-in, prohibited medication use, HbA1c ≥ 10%, TSH below normal, ALT or AST \> 2× ULN, serum potassium below normal, severe renal impairment (eGFR \< 30 mL/min/1.73m²), clinically significant ECG changes or QTc \> 450 ms, or any abnormality making participant unsuitable.
