NCT05286528

Brief Summary

The objectives of this study are to describe patient demographics, clinical and disease characteristics and treatment patterns of Chronic Lymphoid Leukaemia (CML) in Hungary. The primary endpoint of this study is the overall survival of CML patients treated with tyrosine kinase inhibitors in Hungary. The Overall Survival (OS) of all enrolled patients, OS by sequence pattern and by the number of treatment lines will be analyzed. Secondary objectives are description of the treatment length in 1st and later lines, incidence and prevalence of CML, the patient demographics (as age, gender, comorbidities), average number of patients' comorbidities, most frequent comorbidities and patient number with comorbidities at baseline and at different treatment lines by investigated Thyrosine Kinase Inhibitor (TKI), distribution of the investigated TKI therapies by treatment lines

Outcome Measures

Primary Outcomes (4)

  • Overall Survival Rate: All Participants

    Overall survival rate in this study was defined as percentage of participants alive during analysis period of 01-January-2011 till 30-June-2020. 5 years overall survival rate was demonstrated with Kaplan-Meier curve.

    5 years, during analysis period from 01-January-2011 till 30-June-2020 (retrieved data assessed in this observational study for approximately 1.2 years)

  • Overall Survival Rate: Type of First Line TKI

    Overall survival rate in this study was defined as percentage of participants alive during analysis period of 01-January-2011 till 30-June-2020. 5 years overall survival rate was demonstrated with Kaplan-Meier curve.
