Overview
Brief Summary
A retrospective, non-interventional cohort study design using data obtained from the Flatiron Health oncology electronic health record (EHR)-derived de-identified database, was used to address the study objectives.
The overall asciminib cohort included adult patients with Philadelphia positive (Ph+) chronic myeloid leukemia (CML) in chronic phase (CML-CP), with or without the T3151 mutation, who initiated asciminib in any line of therapy. The third-line or later (3L+) asciminib cohort included adult patients with Ph+ CML-CP who did not have T315I mutation and initiated asciminib after prior use of at least 2 different tyrosine kinase inhibitors (TKIs) or omacetaxine. The 3L asciminib cohort included the subgroup of the 3L+ asciminib cohort who initiated asciminib after prior use of 2 different TKIs or omacetaxine. The fourth-line or later (4L+) asciminib cohort included the subgroup of the 3L+ asciminib cohort who initiated asciminib after prior use of at least 3 different TKIs or omacetaxine.

Outcomes
Primary Outcomes
Age at Index Date
Time Frame: Up to 137 months
Index date was defined as the date of initiation for asciminib.
Number of Patients Categorized by the Five Most Common Baseline Comorbidities
Time Frame: Baseline
Baseline was defined as the time between the date of initial CML diagnosis up to (and excluding) the date of asciminib initiation (index date).
Number of Patients by Most Common Treatment Sequence
Time Frame: From initial CML diagnosis until the end of study period, up to 143 months
Gender at Index Date
Time Frame: Up to 137 months
Index date was defined as the date of initiation for asciminib.
Number of Patients by First Observed Line of Therapy with Asciminib at Index Date
Time Frame: Up to 137 months
Index date was defined as the date of initiation for asciminib.
Asciminib Treatment Persistence Rate Post-Index Date
Time Frame: Week 12, week 24 post-index date
Index date was defined as the date of initiation for asciminib.
Eastern Cooperative Oncology Group Performance Score (ECOG-PS) at Index Date
Time Frame: Up to 137 months
ECOG-PS describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.). Scores ranged from a lower value of 0 (fully active, able to carry on all pre-disease performance without restriction) up to 4 (completely disabled; cannot carry on any selfcare; totally confined to bed or chair). Index date was defined as the date of initiation for asciminib.
Median Duration of Observation from Index Date to the end of the Study Period
Time Frame: Up to 13 months
The study period was defined as the time between the index date (inclusive) until the earliest of stem-cell transplant (SCT), death, loss-to-follow-up (i.e., last activity in the electronic medical record data), or end of data availability (i.e., 30 November 2022). The index date was the date of initiation for asciminib.
Race at Index Date
Time Frame: Up to 137 months
Index date was defined as the date of initiation for asciminib.
Type of Practice at Index Date
Time Frame: Up to 137 months
Types of practices included: community and academic practices. Index date was defined as the date of initiation for asciminib.
Number of Patients Categorized by Dosage of Asciminib at Index Date
Time Frame: Up to 137 months
Index date was defined as the date of initiation for asciminib.
Number of Patients by Type of First Tyrosine Kinase Inhibitor (TKI) Received Before Asciminib Initiation
Time Frame: Up to 137 months
Number of Patients by Type of TKI Received Anytime Before Asciminib Initiation
Time Frame: Up to 137 months
Number of Patients by Type of TKI Received Immediately Before Asciminib Initiation
Time Frame: Up to 137 months
Number of Patients Categorized by Last Molecular Response (MR) Achieved Within 3-months Prior to Index Date
Time Frame: Up to 3 months pre-index date
MR categories included: * MR0 (BCR::ABL1 greater than 10%) * MR1 (BCR::ABL1 less than or equal to 10%) * MR2 (BCR::ABL1 less than or equal to 1%) * MR3/Major MR (BCR::ABL1 less than or equal to 0.1%) * MR4 or better (BCR::ABL1 less than or equal to 0.01%) Index date was defined as the date of initiation for asciminib.
Number of Patients by Status at End of First Observed Line of Therapy with Asciminib
Time Frame: From date of asciminib initiation to end of study period, up to 13 months
Status: * Continued asciminib treatment (included dose change/held). * Discontinued asciminib treatment.
Secondary Outcomes

- Number of Patients With one or More MR Test Post-index Date who Achieved or Maintained MR2(Week 12, week 24 post-index date)
- Number of Patients Without MR3/MMR Prior to Asciminib Initiation who Achieved MR3/MMR Post-index Date(Week 12, week 24 post-index date)
- Median Time to MR2 Post-index Date Among Patients Without MR2 Prior to Asciminib Initiation(From index date until the end of study period, up to 13 months)
- Median Time to MR3/MMR Post-index Date Among Patients Without MR3/MMR Prior to Asciminib Initiation(From index date until the end of study period, up to 13 months)
- Number of Patients Categorized by Best Molecular Response (MR) Achieved Within 12-months Post-index Date(12 months post-index date)
- Number of Patients Without MR2 Prior to Asciminib Initiation who Achieved MR2 Post-index Date(Week 12, week 24 post-index date)
