• Sex: All
• Target Recruitment: 950

Inclusion Criteria

1. Written informed consent must be obtained before any assessment is performed
2. Males and females of any race who are between 18 and 65 years old at the time informed
consent is obtained.
3. Physician diagnosis of asthma, as per GINA (2009) guidelines, and currently prescribed ICS therapy.
4. Patients with a pre-bronchodilator FEV1 value of 40% to 80% of individual predicted value at screening and at randomization, and the value at the randomization should be within 15% of the screening FEV1. The results of spirometry should meet the ATS/ERS criteria for acceptability and repeatability.
5. Patients should be allergic or atopic, as diagnosed historically or prior to entry into the study by either a skin prick test (= 3mm diameter above background) or a positive specific IgE (e.g. RAST/CAP) test (>0.35 IU eq./ml).
6. Patients who are demonstrated to have reversible airway obstruction or airways hyperreactivity or have shown either of such responses in previous test(s) within the last year.
• Reversible airway obstruction is defined as an increase of =12% and =200 ml in FEV1 over the patient’s pre-bronchodilator value in litres within 10-15 minutes after inhaling a total of 360 µg of albuterol or 400 µg salbutamol via MDI (reversibility test). The administration of albuterol or salbutamol for the reversibility test is to be within 30 minutes after pre-bronchodilator spirometry.
• A positive airways hyper-reactivity (AHR) test result is defined as a provoked fall in FEV1 of 20% (PC20) by methacholine at =8 mg/ml when not on ICS or =16 mg/ml on ICS therapy.
7. An ACQ score = 1.5 at randomisation.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 950
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1. Use of other investigational drugs at the time of enrollment, or within 30 days or 5 halflives
of enrollment, whichever is longer.
2. History of hypersensitivity to any of the study drugs or to drugs of similar chemical
classes (CRTh2 antagonists).
3. History of long QT syndrome or whose QTc interval (Fridericia’s) is prolonged > 450 msec for males and females at screening as assessed by central ECG interpretation.
4. History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.
5. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (> 5 mIU/mL).
6. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use effective contraception during the study and for 4 days (5
half-lives) after treatment. Effective contraception methods are defined in the protocol.
7. Patients with serious co-morbidities including uncontrolled diabetes (HbA1c =8%), heart
failure, cancer, neurodegenerative diseases, rheumatoid arthritis and other autoimmune
diseases, other lung diseases including chronic bronchitis, chronic obstructive pulmonary
disease or emphysema or other conditions characterised by eosinophilia and pulmonary
symptoms (i.e. Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis,
eosinophilic pneumonia, etc.).
8. Acute illness other than asthma at the start of the study
9. History of life-threatening asthma, including a history of significant hypercarbia (pCO2>45mmHg), prior intubation, respiratory arrest, or seizures as a result of asthma.
10. History of alcohol or other substance abuse.
11. Patients who have had a respiratory tract infection within 4 weeks of the screening visit.
Patients who develop a respiratory tract infection between screening and the randomization visit must be screen failed, and may be permitted to re-enroll at a later date.
12. Patients who have been hospitalized due to their asthma, or that have required treatment
with systemic steroids, within 6 weeks of the screening visit.
13. Patients with clinically significant laboratory abnormalities (not associated with the study
indication) at screening including (but not limited to):
• Total white blood cell count <2500 cells/µL at screening.
• AST or ALT>2.0 X ULN or total bilirubin >1.3 X ULN at screening.
• Estimated Glomerular Filtration Rate (eGFR) by the MDRD equation <55 mL/minute/1.73 m2 at screening.
14. Patients who have a clinically significant abnormality on a 12-lead ECG recorded within
one month prior to or at screening.
15. Current smokers or ex-smokers who stopped smoking within 6 months prior to screening or have a smoking history of = 10 pack years.
16. Patients with a body mass index (BMI) < 17 or > 40 kg/m2.
