Study groups in NCT05779007
Study groupRoleWhat they receive
Pirfenidone initiators cohortIPF patients from the Optum Research Database (ORD) who presented at least one pirfenidone prescription during the identification period (the date of first prescription for pirfenidone was considered the index date, between October 2014 up to December 2021) and with at least 12 months of continuous enrollment in the health plan during pre-and post-index period.
Receives: Drug: Pirfenidone
Nintedanib initiators cohortIPF patients from the Optum Research Database (ORD) who presented at least one nintedanib prescription during the identification period (the date of first prescription for nintedanib was considered the index date, between October 2014 up to December 2021) and with at least 12 months of continuous enrollment in the health plan during pre-and post-index period.
Receives: Drug: Nintedanib

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Dose Reduction and/or Temporary Dose Reduction (Sub-optimal Dose) by 12 Months

    Number of patients with sub-optimal dose was be defined as patients with an average daily dose not following the prescribing information of nintedanib and pirfenidone for at least 90 consecutive days, corresponding to ≤ 66.67% dose strength for pirfenidone and ≤ 66.67% dose strength for nintedanib.

    Number of patients with sub-optimal dosing by month 12 is reported.

    Measured: From individual index date up to 12 months.

Secondary outcomes (1)
  1. Time to Treatment Discontinuation

    Treatment discontinuation was defined as presence of ninety or more days gap in refilling a prescription of the drug (pirfenidone or nintedanib)

    Measured: From individual index date up to 12 months.

Individual data sharing
No: 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).
