NCT05501639

Brief Summary

The purpose of this study is to conduct a comparative analysis of patients using Tiotropium in combination with Inhaled Corticosteroids (ICS) versus those that use long-acting β2-agonists (LABA) medication in combination with ICS.

Outcome Measures

Primary Outcomes (1)

  • Time to First Severe Exacerbation

    Severe exacerbation defined as: * Hospitalization with primary diagnosis of asthma or * Emergency room (ER) visit with primary diagnosis of asthma The analysis of this endpoint is based on number of observations (exacerbations). Index date is defined as date when patient entered the cohort. Design 1: A time-varying covariate approach to classify drug exposure time for each comparator drug during follow up was used. For each individual study drug, medication exposure + non-exposure windows during the follow-up time for each medication were identified/defined using date of prescription filled + days' supply listed on prescription claim + 50% additional days.

    From index date to first severe exacerbation, up to 1 year.

Secondary Outcomes (6)

  • Time to First Moderate-or-severe Exacerbation

    From index date to first moderate-or-severe exacerbation, up to 1 year.

  • Percentage of Patients With Exacerbation

    From index date through first report of exacerbation, up to 1 year.

  • Rate of Exacerbation at 6 Months and One Year

    at 6 months and one year

  • Percentage of Patients With Health Care Resource Utilization (HCRU)

    From index date to end of follow-up, up to 1 year.

  • Health Care Resource Utilization (HCRU)

    From index date to end of follow-up, up to 1 year.

Study Population

Patients with least two asthma diagnosis will be included. Patients will be required to have enrollment for at least 6 months prior to ICS+Tio or ICS/LABA use.

You may qualify if:

  • Patients with least two asthma diagnosis
  • Patients will be required to be concurrently on inhaled corticosteroids (ICS)+Tiotropium (tio) (specifically Tiotropium Respimat® 1.25 mcg) or ICS/LABA
  • Patients will be required to have enrollment for at least 6 months prior to ICS+Tio or ICS/LABA use

You may not qualify if:

  • Patients with least two diagnosis of chronic obstructive pulmonary disease (COPD) at any time during the study period
  • Patients less than 12 years of age
  • Patients on biologics within 6 months prior to ICS+Tio or ICS/LABA use
  • Patients with prior Tio or ICS/LABA use during the 6-month baseline period
  • Patients with urinary bladder obstruction, urinary retention, and glaucoma
  • After the propensity score matching (PSM) process, unmatched patients

Data Sharing

IPD Sharing
Will not share

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
