Eligibility criteria:

        Inclusion Criteria for Screening

          -  Age: 18 years of age or older at the time of signing the informed consent.

          -  Diagnosis: Subjects with a diagnosis of asthma as defined by the National Institutes
             of Health at least one year prior to Visit 0.

          -  Symptomatic: Subjects with inadequately controlled asthma (ACQ-6 score >=1.5) despite
             ICS/LABA maintenance therapy at Visit 1.

          -  Asthma Control: In the 1 year prior to Visit 1

               -  A documented healthcare contact for acute asthma symptoms or

               -  A documented temporary change in asthma therapy for acute asthma symptoms,
                  according to a pre-specified asthma action plan (or equivalent)

          -  Current Asthma Maintenance Therapy: Subjects are eligible if they have required daily
             ICS/LABA for at least 12 weeks prior to Visit 0 with no changes to maintenance asthma
             medications during the 6 weeks immediately prior to Visit 0 (including no changes to a
             stable total dose of ICS of >250 mcg/day fluticasone proprionate [FP, or equivalent]).

          -  Spirometry: A best pre-bronchodilator morning (ante meridian [AM]) FEV1 >=30% and <85%
             of the predicted normal value at Visit 1. Predicted values will be based upon the
             European Respiratory Society (ERS) Global Lung Function Initiative.

          -  Reversibility of Disease: airway reversibility defined as >=12% and >=200 milliliter
             (mL) increase in FEV1 between 20 and 60 minutes following 4 inhalations of
             albuterol/salbutamol aerosol at Visit 1.

          -  If the subject does not meet the above reversibility criteria at Visit 1 then the
             reversibility assessment may be repeated once within 7 days of Visit 1 if either
             criteria a) or b) are met: a) >=9% increase in FEV1 between 20 and 60 minutes
             following 4 inhalations of albuterol/salbutamol aerosol at Visit 1. b) Documented
             evidence of a reversibility assessment within 1 year prior to Visit 1 which
             demonstrated a post-bronchodilator increase in FEV1 of >=12% and >=200 mL.

        Should the subject successfully demonstrate airway reversibility (defined as >=12% and
        >=200 mL increase in FEV1 between 20 and 60 minutes following 4 inhalations of
        albuterol/salbutamol aerosol) at the second attempt then, provided that all other
        eligibility criteria assessed at Visit 1 are met, the subject may enter the 3-week run-in
        period.

          -  Short-Acting beta2 Agonists (SABAs): All subjects must be able to replace their
             current SABA inhaler with albuterol/salbutamol aerosol inhaler at Visit 1 as needed
             for the duration of the study. Subjects must be judged capable of withholding
             albuterol/salbutamol for at least 6 hours prior to study visits.

          -  Male or eligible Female, defined as having documentation of non-reproductive potential
             or reproductive potential as follows:

        A female subject is eligible to participate if she is not pregnant (as confirmed by a
        negative serum human chorionic gonadotrophin (hCG) test), not lactating, is not planning on
        becoming pregnant during the study and at least one of the following conditions applies:
        Non-reproductive potential defined as pre-menopausal females with documented tubal ligation
        or documented hysteroscopic tubal occlusion procedure with follow-up confirmation of
        bilateral tubal occlusion or hysterectomy or documented bilateral oophorectomy;
        Postmenopausal defined as 12 months of spontaneous amenorrhea with an appropriate clinical
        profile (e.g., age appropriate, >45 years, in the absence of hormone replacement therapy).
        In questionable cases for women <60 years of age, a blood sample with simultaneous follicle
        stimulating hormone and estradiol falling into the central laboratory's postmenopausal
        reference range is confirmatory. Females under 60 years of age, who are on hormone
        replacement therapy (HRT) and whose menopausal status is in doubt, are required to use a
        highly effective method to avoid pregnancy if they wish to continue their HRT during the
        study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status
        prior to study enrolment. For most forms of HRT, at least 2 to 4 weeks will elapse between
        the cessation of therapy and the blood draw; this interval depends on the type and dosage
        of HRT. Following confirmation of their post-menopausal status, subjects can resume use of
        HRT during the study without use of a highly effective method to avoid pregnancy;
        Reproductive potential and agrees to follow one of the options listed in the Modified List
        of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential
        (FRP) from the screening visit until after the last dose of study medication and completion
        of the follow-up visit. The Investigator is responsible for ensuring that subjects
        understand how to properly use these methods of contraception.

          -  Informed Consent: Able to give written informed consent prior to participation in the
             study, which will include the ability to comply with the requirements and restrictions
             listed in the consent form and in this protocol. Subjects must be able to read,
             comprehend, and write at a level sufficient to complete study related materials.

        Exclusion Criteria for Screening

          -  Pneumonia: Chest X-ray documented pneumonia in the 6 weeks prior to Visit 1.

          -  Asthma Exacerbation: Any asthma exacerbation requiring a change in maintenance asthma
             therapy in the 6 weeks prior to Visit 1. Note: Subjects requiring a temporary change
             in asthma therapy (e.g., oral corticosteroids or increased dose of ICS) to treat an
             exacerbation in the 6 weeks prior to Visit 1 are not explicitly excluded at Visit 1
             provided that, at the Investigator's discretion, the subject's condition is stable
             after they have resumed their pre-exacerbation maintenance asthma therapy (without
             modification) and they are considered appropriate for enrolment into this study of up
             to 12 month's duration.

          -  Chronic Obstructive Pulmonary Disease: Subjects with the diagnosis of chronic
             obstructive pulmonary disease, as per Global Initiative for Chronic Obstructive Lung

             especially tobacco smoke, occupational dusts and chemicals, smoke from home cooking
             and heating fuels) and a post-albuterol/salbutamol FEV1/Forced Vital Capacity (FVC)
             ratio of <0.70 and a post-albuterol/salbutamol FEV1 of =<70% of predicted normal

             sensory, endocrine (including uncontrolled diabetes or thyroid disease) or
             hematological abnormalities that are uncontrolled. Significant is defined as any
             disease that, in the opinion of the Investigator, would put the safety of the subject
             at risk through participation, or which would affect the efficacy or safety analysis
             if the disease/condition exacerbated during the study.

          -  Unstable liver disease as defined by the presence of ascites, encephalopathy,
             coagulopathy, hypoalbuminemia, esophageal or gastric varices or persistent jaundice,
             cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or
             asymptomatic gallstones). Note: Chronic stable hepatitis B and C are acceptable if the
             subject otherwise meets entry criteria.

          -  Clinically significant Electrocardiogram abnormality: Evidence of a clinically
             significant abnormality in the 12-lead ECG performed during screening. The
             Investigator will determine the clinical significance of each abnormal ECG finding in
             relation to the subject's medical history and exclude subjects who would be at undue
             risk by participating in the trial. An abnormal and clinically significant finding is
             defined as a 12-lead tracing that is interpreted as, but not limited to, any of the

             (QTcF) >=500 milliseconds (msec) in subjects with QRS <120 msec and QTcF >=530 msec in
             subjects with QRS >=120 msec.

          -  Unstable or life threatening cardiac disease: Subjects with any of the following at
             Screening (Visit 1) would be excluded: Myocardial infarction or unstable angina in the
             last 6 months; Unstable or life threatening cardiac arrhythmia requiring intervention
             in the last 3 months; New York Heart Association (NYHA) Class IV Heart failure.

          -  Antimuscarinic effects: Subjects with a medical condition such as narrow-angle
             glaucoma, urinary retention, prostatic hypertrophy or bladder neck obstruction should
             only be included if in the opinion of the Investigator the benefit outweighs the risk
             and that the condition would not contraindicate study participation.

          -  Cancer: Subjects with carcinoma that has not been in complete remission for at least 5
             years. Subjects who have had carcinoma in situ of the cervix, squamous cell carcinoma
             and basal cell carcinoma of the skin would not be excluded based on the 5 year waiting
             period if the subject has been considered cured by treatment.

          -  Questionable validity of consent: Subjects with a history of psychiatric disease,
             intellectual deficiency, poor motivation or other conditions that will limit the
             validity of informed consent to participate in the study.

             inhaled tobacco products within the 12 months prior to Visit 1 [i.e., cigarettes,
             e-cigarettes/vaping, cigars or pipe tobacco]) or former smokers with a smoking history
             of >=10 pack years (e.g., >=20 cigarettes/day for 10 years).
