Real-World Treatment Patterns and Outcomes Among Patients With Chronic Myeloid Leukemia in Earlier Lines of Therapy

Completed

Conditions studied: Chronic Myeloid Leukemia

In brief

This was a retrospective, non-interventional, observational cohort study using Optum's de-identified Clinformatics® Data Mart Database. Adult patients newly diagnosed with chronic myeloid leukemia (CML) treated with tyrosine kinase inhibitors (TKIs) were identified using the Optum database and classified into the following cohorts: * First treatment cohort: Patients newly diagnosed with CML who received first treatment with a TKI. * Second treatment cohort: Patients from first treatment cohort with a subsequent line of therapy (i.e., second treatment) with a TKI. The observation period spanned from the start of data availability (i.e., 01 January 2007) to the earliest of end of data (i.e., 30 June 2022), end of continuous health plan enrollment, or death (if available). The index date was defined as the first treatment initiation for the first treatment TKI cohort and as the second treatment initiation for the second treatment TKI cohort. The baseline period consisted of the 6 months prior to the index date. The follow-up period started on the index date and ended at the earliest of end of observation period or hematopoietic stem cell transplantation (HSCT).
