Brief Summary

This is a multi-centre, randomised, double-blind, double-dummy, two way cross-over, 12 week non inferiority study to evaluate the efficacy, safety, and tolerability of FSC 250/50 mcg capsule-based inhaler and FSC 250/50 mcg multi-dose inhaler each administered BID in adults and adolescents with asthma. The primary objective of this study is to demonstrate that FSC 250/50 mcg administered BID by capsule-based inhaler is non-inferior compared to FSC 250/50 mcg administered BID by multi-dose inhaler . The study consists of six phases: Pre-screening, Screening/Run-in (3 weeks), Treatment Period 1 (12 weeks), Washout (minimum 3 weeks), Treatment Period 2 (12 weeks) and Follow-up (1 week). The total duration of the study for each subject will be at least 31 weeks.

Eligibility Criteria

Inclusion Criteria

• Male or female >=12 and <=80 years of age at the time of signing the informed consent
• A female subject is eligible to participate if she is of:
• Non-childbearing potential defined as premenopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone >40 milli international unit per milliliter (mIU/mL) and oestradiol <40 picogram (pg)/mL [<147 picomole per liter (pmol/L)] is confirmatory); Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods (i.e., in accordance with the approved product label and the instructions of the physician for the duration of the study from Screening to follow-up contact) if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrolment. For most forms of HRT, at least 2 to 4 weeks should elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. After confirmation of their postmenopausal status, they can resume use of HRT during the study without use of a contraceptive method; child-bearing potential and is abstinent or agrees to use one of the contraception methods for an appropriate period of time (as determined by the product label or investigator) before the start of dosing to sufficiently minimise the risk of pregnancy at that point. Female subjects must agree to use contraception until at least 2 days post the last dose of study treatment; abstinence from penile-vaginal intercourse must be consistent with the preferred and usual lifestyle of the subject.
• Severity of disease: A best prebronchodilator FEV1 of >=40% to <=85% of the predicted normal value at Visit 1 (Screening and Run-in Visit). Predicted values will be based upon National Health and Nutrition Examination Survey (NHANES) III. If a subject is recorded as having Hispanic or Latino ethnicity, then the Mexican-American equations will be used (irrespective of race). If a subject is recorded as being of African-American/African heritage race, then the African American equations will be used. If a subject is recorded as being of Asian race, then the Asian adjustment will be used. Otherwise, the Caucasian equations will be used.
• Reversibility of disease: Demonstrated >=12% and >=200 mL reversibility of FEV1 within 10 to 40 minutes after 2 to 4 inhalations of salbutamol inhalation aerosol (or equivalent nebulised treatment with salbutamol solution) at Visit 1 (Screening and Run-in Visit).
• Current anti-asthma therapy: All subjects must be using an Inhaled Corticosteroid (ICS) with or without long-acting beta-adrenergic agonist (LABA) for at least 8 weeks and a stable dose for at least 4 weeks before Visit 1 (Screening and Run-in Visit). Two populations are eligible for enrolment: - Subjects maintained on ICS monotherapy (FP 100 mcg to 250 mcg BID or equivalent) for at least 8 weeks and a stable dose for at least 4 weeks before Visit 1 (Screening and Run-in Visit) or Subjects maintained on an ICS/LABA combination product (e.g., Fluticasone propionate/salmeterol 100/50 or 250/50 mcg BID or equivalent by other combination products or by separate inhalers) for at least 8 weeks and a stable dose for at least 4 weeks before Visit 1 (Screening and Run-in Visit). Subjects taking budesonide/formoterol or beclomethasone/formoterol as needed must switch to budesonide/formoterol maintenance dosing (excluding the highest dose) with use of a SABA for symptom relief at least 8 weeks and a stable dose for at least 4 weeks before Visit 1 (Screening and Run-in Visit). NOTE: Subjects on low dose ICS monotherapy should only be enrolled, if, in the opinion of the investigator, after review of their medical history and clinical examination, they will be able to benefit from both an increase in ICS dose and the addition of LABA therapy arising from and ICS/LABA combination.
• Ability to withhold LABA therapy: Other than what is provided during the study, LABA therapy is not permitted on the day of Visit 1 (Screening and Run-in Visit) and throughout the entire study. The last dose of LABA and LABA/ICS combinations are to be taken on the day before Visit 1. Sites should contact the medical monitor to discuss subject eligibility, for doses of commonly prescribed ICS and ICS/LABA combination medication; as mentioned in the study protocol.
• SABA: All subjects must be able to replace their current SABA treatment with rescue salbutamol/albuterol at Visit 1 (Screening and Run-in Visit) for use as needed for the duration of the study. Subjects must be able to withhold salbutamol/albuterol for at least 6 hours before each study visit.
• Liver safety criteria: Alanine aminotransferase (ALT) <=2 the upper limit of normal (ULN), Alkaline phosphatase and bilirubin <=1.5 ULN (isolated bilirubin >1.5 ULN is acceptable if bilirubin is fractionated and direct bilirubin is <35%) at Visit 1 (Screening and Run-in Visit).
• Electrocardiogram (ECG) safety criteria: The subject must have no ECG abnormalities that would, in the opinion of investigator, compromise subject safety, or significantly affect subject's ability to complete the trial. As such, the investigator will determine the clinical significance of any ECG abnormality and determine if a subject is precluded from entering the study. At Visit 1 (Screening and Run-in Visit), ECG safety criteria must be: QT interval corrected for heart rate (QTc) or QT interval corrected for heart rate according to Fridericia formula (QTcF) <450 msec or QTc <480 msec for subjects with bundle branch block; Investigators will be responsible for ensuring appropriate clinical interpretation of ECGs.
• The subject and/or the subject's legal guardian (if applicable) must be capable of giving informed consent/assent, which includes compliance with the study requirements and restrictions listed in the consent/assent form.
