Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

To evaluate the feasibility and safety of gradual interval prolonging of biologics during ~1 year in patients with severe asthma

Secondary objectives 8

  1. To evaluate the change in exacerbation frequency after gradual interval prolonging of biologics during ~1 year
  2. To evaluate the change in blood eosinophile count after gradual interval prolonging of biologics during ~1 year
  3. To evaluate the change FeNO after gradual interval prolonging of biologics during ~1 year
  4. To evaluate the change in lung function after gradual interval prolonging of biologics during ~1 year
  5. To evaluate the change in symptom scores after gradual interval prolonging of biologics during ~1 year
  6. To evaluate whether algorithm guided interval prolongation with ACQ, FeNO and blood eosinophil levels is equal to regular clinical care with respect to asthma control at base line.
  7. To evaluate severeness and cause of exacerbations during interval prolonging of biologics
  8. To evaluate the change in use of inhaled corticosteroids during interval prolongation as compared to baseline

  2. ≥18 years of age
  3. 0 or 1 exacerbation in the past 12 months
  4. Baseline ACQ < 2.0
  5. Blood eosinophil count ≤0.3 +10^9/L for anti-IL-5(R)/Tezepelumab, ≤1.5 +10^9/L for Dupilumab

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Maintained asthma control after ~1 year of study participation with at least one step of interval prolongation. Asthma control is defined as not more than one additional exacerbation compared to baseline frequency during ~1 year and a ACQ < 2.0 at the last study visit. An exacerbation is defined as an acute worsening of symptoms lasting more than 48 hours, as assessed by the treating physician.

Secondary endpoints 18

  1. Exacerbation frequency per year.
  2. Blood eosinophile count in *10^9 cells per liter
  3. FeNO in parts per billion (ppb)
  4. Forced Expiratory Volume in 1 second (FEV1)
  5. Forced Vital Capacity (FVC)
  6. FEV1/FVC
  7. Asthma Control Questionnaire (ACQ)
  8. Severe Asthma Questionnaire (SAQ)
  9. Sino-Nasal Outcome Test (SNOT-22)
  10. Strict asthma control after algorithm guided interval prolongation for ~1 year. Strict asthma control is defined as ΔACQ < 0.5 and control of biomarkers.
  11. Detection of respiratory viruses during asthma exacerbations by PCR on nasopharyngeal swab
  12. Blood eosinophile count in *10^9 cells per liter during asthma exacerbations
  13. FeNO in parts per billion (ppb) during asthma exacerbations
  14. ACQ during asthma exacerbations
  15. SAQ during asthma exacerbations
  16. Dosage of Inhaled Corticosteroids (ICS)
  17. Inhaler technique
  18. 5 – item Medication Adherence Report Scale (MARS-5)
