About this study
Official title: Treatment Patterns and Outcomes Among Patients With Chronic Myeloid Leukemia (CML) in All Lines of Therapy: An Analysis of Medicare Fee-for-Service (FFS) Data
The aim of this study was to evaluate the real-world treatment patterns, healthcare resource use and costs among patients newly diagnosed with CML who were treated with tyrosine kinase inhibitors (TKIs) in first- and second-line therapy.
Read the detailed description
The study used claims from Medicare FFS data from 1 January 2016 to 31 December 2022 (observation period). The patient identification period spanned from 1 January 2017 to 30 June 2022. The index date was the date of treatment line initiation. Patients were followed from index date until death, end of enrollment, or study end (31 December 2022), whichever came first. Each patient's follow-up was variable in length.
Variables were assessed during the follow-up period in first-line (1L) and second-line (2L) treatment cohorts and were stratified by generations of TKIs and treatment profiles. Patients were categorized into non-optimal treatment (NOPT) profiles and reference groups, and treatment patterns, healthcare resource utilization (HCRU), and payer healthcare costs were summarized descriptively for each group.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Patients Who Switched to Another CML-related Treatment by TKI Generation and Treatment Profile (time frame: Up to approximately 6 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
