Who can take part

You may be able to join if

  • Able to understand and give written informed consent and has signed a written informed consent form (ICF) approved by the Investigator's Institutional Review Board (IRB)/Ethics Committee (EC), prior to conducting any study related procedures (including withholding of any asthma medications required for procedures)
  • Women are authorized to participate if they meet the following criteria: Female participants who cannot bear children as evidenced by: Women ""not of childbearing potential"" are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrhoeic for ≥12 months prior to the planned date of randomization without an alternative medical cause. The following age-specific requirements apply - Women <50 years old will be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatment and follicle stimulating hormone (FSH) levels in the postmenopausal range. Until FSH is documented to be within menopausal range treat the participant as WOCBP - Women ≥50 years old will be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatment. If criteria not met, participant should be regarded as having child bearing potential. Female participant capable of having children and both of the following conditions are met: - Have a negative urine pregnancy test prior to administration of the IP and - Must agree to use a highly effective method of birth control (confirmed by the investigator) from randomization throughout the study duration and within 12 weeks after last dose of IP. Highly effective methods ( those that can achieve a failure rate of less than 1% per year when used consistently and correctly) ) include: -Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation- oral, intravaginal, or transdermal -Progestogen-only hormonal contraception associated with inhibition of ovulation- oral, injectable, or implantable -Intrauterine device (IUD) -Intrauterine hormone-releasing system (IUS) -Bilateral tubal occlusion -Sexual abstinence, ie. refraining from heterosexual intercourse (The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the participant) -Vasectomized sexual partner provided that partner is the sole sexual partner of the WOCBP study participant and that the vasectomized partner has received medical assessment of the surgical success
  • Acceptable inhaler technique, as judged by the investigator.
  • ACQ-6 >1.5
  • Compliance with inhaled asthma maintenance medication >70% (calculated in the period from Visit 2 to Visit 3). The screening/run-in period may be extended to accommodate this criterion
  • Fewer than 12 exacerbations within the 6 months prior to Visit 3

  • Current active liver disease, except for chronic stable hepatitis B and C, or other stable chronic liver disease are acceptable if participant otherwise meets eligibility criteria.
