Inclusion and exclusion criteria

Inclusion Criteria

Informed Consent
1 Capable of giving signed informed consent as described in the protocol which included compliance with the requirements and restrictions listed in the ICF and protocol
Type of Participant and Disease Characteristics
3 Diagnosis of asthma, by a prescribing health care professional
4 ≥ 2 prescriptions for a SABA inhaler in the past 12 months prior to Visit 1 (and the expectation that the participant will probably use their rescue inhaler ≥ 2 days per week as this is required at Visit 2 for randomization following the Lead-in Period)
5 FeNO ≥ 25 ppb at Visit 1
Sex and Contraceptive/Barrier Requirements
7 Female participants: Females must be not of childbearing potential or using a form of birth control as defined below:
• Females not of childbearing potential are defined as females who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. The following age-specific requirements apply:
o Females < 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and in the absence of any alternative medical cause, as judged by the investigator.
o Females ≥ 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.
• Female participants of childbearing potential must use a highly effective form of birth control. A highly effective method of contraception is defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly. Females of childbearing potential who are sexually active with a non-sterilized male partner must agree to use one highly effective method of birth control, as defined below, from enrolment throughout the study and until at least 14 days after last dose of study intervention. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
o All females of childbearing potential must have a negative pregnancy test result at Visit 1.
o Females < 50 years old would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatment and in the absence of any alternative medical cause, as judged by the investigator.
• Highly effective birth control methods are listed below:
o Total sexual abstinence is an acceptable method provided it is the usual lifestyle of the participant (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments).
o Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:
• Oral
• Intravaginal
• Transdermal
o Progestogen-only hormonal contraception associated with inhibition of ovulation:
• Oral
•Injectable
• Implantable
o Intrauterine device or intrauterine hormone-releasing system
o Bilateral tubal occlusion
o Male partner sterilization/vasectomy with documentation of azoospermia prior to the female participant’s entry into the study, and this male is the sole partner for that participant. The documentation on male sterility can come from the site personnel’s review of participant’s medical records, medical examination and/or semen analysis or medical history interview provided by her or her partner.
8 Negative pregnancy test (urine) for female participants of childbearing potential at Visit 1.
Randomization Criteria 5.1.1 at Visit 2 (Week 0)
1 Symptoms requiring rescue medication use for a minimum of 2 days per week for the last 14 days during the Lead-in Period (minimum 4 uses total)
2 At least 80% overall compliance rate for performing daily FeNO and spirometry assessments and completing the twice-daily asthma symptom and rescue medication use diary during the Lead-in Period.

Exclusion Criteria

Medical Conditions
1 Any significant disease or disorder, or evidence of drug/substance abuse which in the investigator’s opinion would pose a risk to participant safety, interfere with the conduct of study, have an impact on the study results, or make it undesirable for the participant to participate in the study.
2 Medical history of life-threatening asthma including intubation and intensive care unit admission.
3 Medical conditions (other than allergic rhinitis) or medications that will influence FeNO, as judged by the investigator.
4 Concurrent respiratory disease: presence of a known pre-existing, clinically important lung condition other than asthma (eg, cystic fibrosis, idiopathic pulmonary fibrosis, pulmonary arterial hypertension, chronic obstructive pulmonary disease).
5 Any disease state or procedure that is likely to necessitate the use of oral/systemic corticosteroids during the Treatment Period, other than asthma.
6 Malignancy: a current malignancy or previous history of cancer in remission for less than 12 months prior to Visit 1 (participants with treated localized squamous cell or basal cell carcinoma of the skin will not be excluded, whereas participants who had melanoma will be excluded). Participants with a history/treatment of malignancy, and which in the investigator’s opinion could compromise the safety of the participant.
7 Other concurrent medical conditions: participants who have known, pre-existing, clinically significant cardiovascular (including clinically significant cardiac arrhythmia and participants with known QT interval corrected for heart rate using the Fridericia formula > 480 ms), endocrine, autoimmune, metabolic, neurological, renal, gastrointestinal, hepatic, haematological or any other system abnormalities that are uncontrolled with standard treatment.
8 Current smokers: previous smokers are allowed to be included provided that they stopped smoking > 12 months prior to Visit 1 AND have a smoking history of ≤ 10 pack-years (includes tobacco, e-cigarettes, vapes, marijuana, etc.).
9 Alcohol/substance abuse: a history (or suspected history) of alcohol misuse or substance abuse within 2 years prior to Visit 1.
Prior/Concomitant Therapy
10 Use of ICS-containing therapy for maintenance or rescue at enrolment. Other therapies for maintenance of asthma control are allowed (leukotriene receptor antagonists and/or antihistamines, for example), but not LAMA or LABA.
11 Use of any systemic or inhaled corticosteroid within 4 weeks of Visit 1
12 Planned use of a nebulizer during the study (between Visits 1 and 5)
Prior/Concurrent Clinical Study Experience
13 Participation in another clinical study with any marketed or investigational anti-allergic or immunosuppressant biologic drug within 4 months or 5 half-lives (whichever is longer) prior to Visit 1.
14 Participation in another clinical study with a non-biologic investigational product or new formulation of a marketed non-biologic drug during the last 30 days prior to Visit 1.
Other Exclusions
15 Participants with a known hypersensitivity to the study drugs or any of the excipients of the products.
16 Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
17 Previous randomization in the present study.
18 For women only: currently pregnant (confirmed with positive pregnancy test), breastfeeding or planned pregnancy during the study.
19 Planned hospitalization during the study that would interfere with study objectives as judged by the investigator.
