Study to Evaluate the Mastery of Inhaler Technique for Budesonide Formoterol (BF) SPIROMAX® as Compared to SYMBICORT® TURBOHALER® as Treatment for Adult Participants With Asthma

This study is conducted to assess whether training participants on proper use of BF SPIROMAX and Symbicort TURBOHALER will improve their device-handling technique and potentially improve their treatment outcome, that is, better asthma control.


Eligibility Criteria:
Inclusion Criteria:

* The participant has a diagnosis of asthma in accordance with Global Initiative for Asthma (GINA) criteria as evidenced by a United Kingdom (UK) quality outcome framework approved Read code (UK diagnostic coding system).
* The participant is receiving step 3 or 4 therapy for asthma as defined by the British Thoracic Society (BTS) guidelines (daily doses of beclomethasone dipropionate \[BDP\]-equivalent ICS) ≥800 mcg to 2000 μg as part of fixed- or free combinations with long-acting β2-agonists (LABA).
* If participant is a female of childbearing potential (post-menarche or less than 2 years post-menopausal or not surgically sterile), the participant must be willing to commit to using a medically accepted method of contraception for the duration of study and 30 days after discontinuing study drug.
* The participant, as judged by the investigator, must be willing and able to understand risks and benefits of study participation to give informed consent and to comply with all study requirements as specified in this protocol for the entire duration of their study participation.
* The participant is SPIROMAX and TURBOHALER naïve (no use of a SYMBICORT TURBOHALER device in the last 6 months, minimizing carryover from prior device use).
* If female and of childbearing potential, the participant must have a negative urine pregnancy test.

  * other criteria apply, please contact the investigator for additional information.

Exclusion Criteria:

* The participant has any clinically significant uncontrolled medical condition (treated or untreated) that, in the judgment of the investigator, will cause participation in the study to be detrimental to the participant.
* The participant has participated in a Teva-sponsored clinical study with BF SPIROMAX in the last 6 months.
* The participant is a pregnant, attempting to become pregnant, or breast feeding. (Any woman becoming pregnant during the study will be withdrawn from the study.)
* The participant has used a clinical trial investigational drug within 1 month before the screening visit.
* The participant has an ongoing asthma exacerbation or has received OCS and/or antibiotics for a lower respiratory condition (proxy measure for identifying an asthma exacerbation and/or lower respiratory infection, suggestive of altered inspiratory capabilities) in the 2 weeks preceding visit 1.
* The participant is currently receiving any OCS (including long or short courses).
* The participant has a significant chronic lower respiratory tract disease other than asthma (for example chronic obstructive pulmonary disease \[COPD\], cystic fibrosis or interstitial lung disease). Conditions that are not predominant, such as minor degrees of bronchiectasis, are not a reason for exclusion.
* The participant has a known allergy or severe sensitivity to the constituents of the study drugs (SPIROMAX or TURBOHALER),for example, to lactose or to milk protein.

  * other criteria apply, please contact the investigator for additional information.
