Study Arms (2)
Group 1 - Participants randomized to receive albuterol/budesonide
EXPERIMENTALParticipants will be randomized based on Visit 1 FeNO levels (\< 50 ppb / ≥ 50 ppb) and geographic region. Participants who are randomized to receive albuterol/budesonide for as-needed rescue therapy will be compared to participants randomized to receive albuterol for as-needed rescue therapy.
Group 2 - Participants randomized to receive albuterol
ACTIVE COMPARATORParticipants will be randomized based on Visit 1 FeNO levels (\< 50 ppb / ≥ 50 ppb) and geographic region. Participants who are randomized to receive albuterol/budesonide for as-needed rescue therapy will be compared to participants randomized to receive albuterol for as-needed rescue therapy.
Interventions
Oral Inhalation. Rescue medication. Unit dose strength of 80 μg budesonide and 90 μg albuterol per actuation
Oral Inhalation. Rescue medication. Unit dose strength of 90μg albuterol per actuation.
Eligibility Criteria
You may qualify if:
- Informed Consent
- 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:
- 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.
- 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.
- All females of childbearing potential must have a negative pregnancy test result at Visit 1.
- 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:
- 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).
- Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:
- Oral
- Intravaginal
- +12 more criteria
You may not qualify if:
- Medical Conditions
- 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.
- Medical history of life-threatening asthma including intubation and intensive care unit admission.
- Medical conditions (other than allergic rhinitis) or medications that will influence FeNO, as judged by the investigator.
- 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).
- Any disease state or procedure that is likely to necessitate the use of oral/systemic corticosteroids during the Treatment Period, other than asthma.
- 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.
- 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.
- 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.).
- Alcohol/substance abuse: a history (or suspected history) of alcohol misuse or substance abuse within 2 years prior to Visit 1.
- Prior/Concomitant Therapy
- 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.
- Use of any systemic or inhaled corticosteroid within 4 weeks of Visit 1
- Planned use of a nebulizer during the study (between Visits 1 and 5)
- Prior/Concurrent Clinical Study Experience
- +7 more criteria
