E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Participants to be included in the study are those who meet all of the following criteria:
Inclusion criteria (for participants on Seretide Accuhaler 250/50 μg at screening):
1. Male and female participants ≥18 years old.
2. Female participants less than one year post-menopausal must have a negative urine
pregnancy test recorded at the screening visit prior to the first dose of study
medication, be non-lactating, and willing to use adequate and highly effective

implants, injectables, combined oral contraceptives, some IUDs (Intrauterine
Device, hormonal), true sexual abstinence, where this is in line with the
preferred and usual lifestyle of the participant, or vasectomised partner.
Note: Periodic abstinence (calendar, ovulation, symptothermal, post-ovulation
methods), declaration of abstinence for duration of study, and withdrawal are not
acceptable methods of contraception).
3. Documented clinical history of asthma for ≥ 6 months prior to screening visit.
4. Using Seretide Accuhaler at a stable dose of 250/50 μg BID at screening for ≥ 8
weeks.

visit.
7. Historical evidence (within past 24 months) of eosinophilic airways disease,
evidenced by sputum eosinophil count ≥ 3% and/or FeNO ≥ 35 ppb.
8. Good compliance with current asthma medication(s) in the Investigators opinion.
9. Willing and able to substitute pre-study prescribed inhaled asthma medication for
the entire duration of the study.
10. Willing and able to attend all study visits.

Inclusion criteria (for participants on equivalent /higher dose or other ICS-LABAs or higher dose of Seretide at screening):

pregnancy test recorded at the screening visit prior to the first dose of study
medication, be non-lactating, and willing to use adequate and highly effective
methods of contraception throughout the study. A highly effective method of birth
control is defined as those which result in a low failure rate (i.e., less than
1% per year) when used consistently and correctly such as sterilisation,
implants, injectables, combined oral contraceptives, some IUDs (Intrauterine
Device, hormonal), true sexual abstinence where this is in line with the
preferred and usual lifestyle of the participant, or vasectomised partner. Note:
Periodic abstinence (calendar, ovulation, symptothermal, post-ovulation methods),
declaration of abstinence for duration of study, and withdrawal are not
acceptable methods of contraception).
3. Documented clinical history of asthma for ≥ 6 months prior to screening visit.
4. R5-R20 ≥ 0.07 kPa/L/s as measured on impulse oscillometry during the screening
visit.

E.4 | Principal exclusion criteria |
Participants to be excluded from the study are those who meet any of the following criteria:
1. Any severe chronic respiratory disease other than asthma.
2. Participant has a smoking history ≥ 10 “pack years” (i.e., at least 1 pack of 20
cigarettes /day for 10 years or 10 packs/day for 1 year, etc.).
3. Current smoking history within 12 months prior to the Screening Visit.
4. Near fatal or life-threatening (including intubation) asthma within the past year.
5. Known history of systemic (injectable or oral) corticosteroid medication within 1
month of Visit 1.
6. Evidence of a clinically unstable disease as determined by medical history or
physical examination that, in the investigator’s opinion, precludes entry into
the study. ‘Clinically unstable’ is defined as any disease that, in the opinion
of the Investigator, would put the participant at risk through study participation,
or which would affect the outcome of the study.
7. In the investigator’s opinion a clinically significant upper or lower respiratory
infection within 4 weeks prior to Visit 1.
8. Current evidence or known history of alcohol and/or substance abuse within 12
months prior to the Screening Visit.

inhibitors, astemizole, quinidine type antiarrhythmics, or potent CYP 3A4
inhibitors such as ketoconazole within 1 week prior to Screening Visit.
10. Current use of bronchodilators / anti-inflammatory agents other than those
specified in the protocol.
11. Known or suspected sensitivity to study drug or excipients.
12. Participation in a clinical drug study within 30 days of the screening visit.
13. Current participation in a clinical study
Exclusion Criteria for subset of participants undergoing OE-MRI and HD-CT
1. Contraindication for MRI scanning (as assessed by local MRI safety
questionnaire), which includes but is not limited to: presence of non-MRI
compatible artificial heart valves, hydrocephalus shunts, intracranial aneurysm
clips, joint replacements or metal implants, pacemakers or other cardiac rhythm

E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of the study is to demonstrate improvement of peripheral airway resistance (R5-R20) from baseline with fluticasone/formoterol breath actuated inhaler (BAI) based on the mean change in R5-R20 from baseline to week 8. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints – Impulse oscillometry (IOS)
• Change in R5-R20 from baseline to week 4 and 9
• Change in R5 (total airway resistance) from baseline to week 4, 8 and 9
• Change in AX (Area under reactance) from baseline to week 4, 8 and 9
• Change in Fres (resonant frequency) from baseline to week 4, 8 and 9
• Change in X5 (reactance at 5Hz) from baseline to week 4, 8 and 9
• Change in delta X5 (within breath reactance difference) from baseline to week 4, 8
and 9
Secondary endpoints – Body plethysmography
• Change in sRaw from baseline to week 8
• Change in lung volumes (RV, TLC, FRC) from baseline to week 8
• Change in RV/TLC from baseline to week 8
Secondary endpoints – Multiple breath nitrogen washout (MBNWT)
• Change in Scond (ventilation heterogeneity in convection dependent airways) from
baseline to week 8 and 9
• Change in Sacin (ventilation heterogeneity in diffusion-dependent airways) from
baseline to week 8 and 9
• Change in lung clearance index (LCI) from baseline to week 8 and 9
Secondary endpoints – Functional respiratory Imaging (FRI)
• Change in FRI parameters from baseline to week 8 and 9
o Lung and Lobar Volumes at FRC and TLC
o Airway Volumes at FRC and TLC (iVaw)
o Air Trapping
o Airway Resistance (iRaw)
o Internal Lobar Airflow Distribution
o Airway Wall Thickness (iVaww)
o Aerosol deposition concentrations
Secondary endpoints – Oxygen enhanced – Magnetic Resonance Imaging (OE-MRI)
• Change in the below parameters from baseline to week 8 and 9;
o Maximal change in the partial pressure of oxygen in lung tissue (Δ PO2max_l).
PO2 is determined from the change in OE-MRI signal due to the inhalation of
elevated levels of oxygen while being scanned. Δ PO2max is the maximum observed
Δ PO2 during the dynamic OE-MRI scanning procedure.
o Median wash-in time (τ_up_l) and wash-out time (τ_down_l). Wash-in and wash-out
times are derived using an exponential model of the kinetics of oxygen delivery
and washout during the dynamic OE-MRI procedure Interquartile range and
histogram skewness (IE γ_1) of wash-in time (τ_up_l) and wash-out time.
Measurements of the heterogeneity of oxygen delivery kinetics across the lung
will reflect local obstruction.
Secondary endpoints – Spirometry
• Change in pre-dose FEV1, FEF25-75, FVC from baseline to weeks 4 and 8
Secondary PRO endpoints
• Change in ACQ-6 and AQLQ from baseline to week 4 and 8
