Study type | Interventional |
The investigators hypothesize that aligning digital data on PEF and adherence with the
patient's own clinical course achieves better asthma control and identifies risks for future
loss of control, compared to current best practice. The study has an adherence optimisation
phase, week 1-12 followed by a medication management phase, week 12 to week 32.
The investigators will compare two asthma education interventions, standard Guideline
recommended practice and feedback from the individual's own INCA device, which assesses
inhaler adherence and relates adherence with changes in PEF and symptom scores over time.
The study has two co-primary endpoints, one will be a comparison of the adherence to therapy
and the other will be a comparison of the appropriateness of medication prescriptions between
the two study groups.

Eligibility |
Inclusion Criteria: - Must be willing to give voluntary informed consent - Must have a clinical diagnosis of asthma supported by objective measures, one of the following by FEV1/FVC <70% and FEV1 <80% or - a 12% change in FEV1 following administration of a beta-agonist or spontaneously over 1 year period, a positive bronchial provocation test, or a 10% variability in PEF within a 7 day period. - Must have a bronchodilator FEV1 > 40% and <80% in the past 1 year - Current unstable asthma i.e. ACT score = 19 at enrolment despite already being managed with GINA step 3-5 therapy. - One or more courses of oral corticosteroids in the prior year, or a hospitalization or ED attendance with an asthma exacerbation in the last year - Age 18 years or older at time of consent. - Capable of understanding and complying with the requirements of the protocol, including the ability to attend for all required visits. - Able and willing to take inhaled medication via a Diskus. - In the opinion of the investigator suitable for use of a salmeterol/fluticasone Diskus inhaler or already using a salmeterol/fluticasone inhaler. Exclusion Criteria: - Have used any investigational product or device within 3 months of the enrolment visit. - Have known previous sensitivity to Seretide (salmeterol/fluticasone). - Have a known significant (in the opinion of the investigator) concurrent medical disease, pregnancy that might mean that the participant cannot complete the study. - Be taking omalizumab or other biological agent used in the treatment of asthma - Concurrent treatment with potent cytochrome P450 3A4 (CYP3A4) inhibitors; Ketoconazole and Ritonavir. - Current smokers and ex-smokers with a greater than 20 pack year history of cigarette smoke |

---|---|---|---|---|
Other | Patient identified goal | Proportion of patients reaching stated clinical goal at week 12 and between that period and week 32. | Baseline to week 32 | |
Primary | Mean rate of actual Adherence to preventer medication | This study will focus on severe asthma patients, who remain uncontrolled and with frequent exacerbations requiring oral steroids and have an Asthma control test (ACT) score of <19 on enrollment. | week 20 through 32 | |
Primary | The between-group difference in the proportion of patients prescribed guideline appropriate medication at the end of the study. | The appropriateness of the prescribed therapy will be verified for each participant after study completion using all available adherence and PEF data. Between-group differences will be further broken down by the following: The proportion of participants prescribed add-on therapy (e.g. Monoclonal antibody therapy) The proportion of participants whose ICS/LABA dose was increased The proportion of participants whose ICS/LABA dose was reduced |
week 20 through 32 | |
Secondary | Cost-effectiveness and economic evaluation of the INCA educational intervention | An economic evaluation of national implementation of the INCA-SUN program will be provided. Data on the cost of the intervention (device, time taken to deliver, cost of training and salary cost of the trainer), medication costs, quality of life, exacerbations and other healthcare utilization and associated costs, such as unscheduled health care visits as well as work productivity losses will be collected alongside the 32-week study. A cost-effectiveness and cost-utility analysis of the intervention compared to the control arm will be performed. Incremental cost-effectiveness ratios (or ICERS) will be calculated from the data, to estimate how much additional cost is required for an additional unit of benefit. |
First 8 weeks of the study and week 20 to 32 | |
Secondary | Change in Asthma Control Test scores at week 32 | ACT scores will be obtained during the study visits. | Baseline to week 32 | |
Secondary | Change in PEF variability | Differences between the two study groups will be calculated | Baseline to week 32 | |
Secondary | Change in AQLQ | AQLQ scores will be obtained during the study visits. | Baseline to week 32 | |
Secondary | Exacerbations over study period | It is hypothesised that with active education, exacerbation frequency can be reduced. | Baseline to week 32 | |
Secondary | To compare the proportion of patients who were clinically stable | The proportion of patients who required no daily reliever use in the month prior to study end will be compared. | First 8 weeks of the study and week 20 to 32 | |
Secondary | Relationship of biomarkers with adherence | A comparison of changes in blood eosinophil's, periostin and Fractional Exhaled Nitric Oxide (FeNO) between the active and control groups will be made.The relationship between 7-day FeNO suppression and clinical and biomarker outcomes will be investigated.10. The relationship between changes in FeNO (characterised into FeNo>45ppb Or FeNO<45ppb) and adherence will also be investigated. | Baseline to week 32 | |
Secondary | The proportion of patients who are refractory to treatment | A comparison of the proportion of patients who are refractory, (defined as having actual adherence =80%, =1 exacerbation, PEF am/pm <80% and ACT =19) will be conducted. | First 8 weeks of the study and week 20 to 32 | |
Secondary | The proportion of patients who are non-adherent and remain uncontrolled | The proportion of patients who are non-adherent and remain uncontrolled, (i.e. Actual Adherence <80%, PEF am/pm <80% and ACT=19) between the active and control groups will be compared. | First 8 weeks of the study and week 20 to 32 | |
Secondary | The proportion of patients with inhaler related side effects | The proportion of patients with inhaler related side effects including oral candidiasis between the active and control groups will be compared. | First 8 weeks of the study and week 20 to 32 |
