NCT04746950

Brief Summary

This is a multicenter non-interventional observational study conducted with a single hand arm to collect real-world data. In this study, commercially available acalabrutinib will be used as prescribed treatment for CLL as per the treating physician's best clinical judgement. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. Treatment assignment will be done according to the current practice. A multi-center collaborative effort in 15 centers selected from regions within Russia will help capture more patients into the database, rather than limiting the data to a single institution. This will be critical for:

  • increasing database sample size
  • reducing bias (single institution bias)
  • increasing result's generalizability to the whole Russian population Being an observational study, only data available from routine clinical practice and standard of care (SoC), in line with national and international laws and regulations, will be recorded. Patients will be treated according to prescribing information, with visit frequency and assessments performed according to routine medical practice and SoC. Only data corresponding to these visits and assessments will be collected as part of the study. Data for the study will be transcribed and entered into an electronic Case Report Form (eCRF) from the patient's medical records. The site investigator will be responsible for ensuring that all required data is collected and entered into the eCRF with the involvement of clinical research organization

Study Population

The Enrolled set will be represented by eligible patients who have signed an informed consent form to participate in the study. It is estimated that approximately 200 patients will be enrolled in the study. Study population will consist of adult patients with diagnosed CLL ≥ 18 years old (treatment naïve (TN) or relapsed/refractory (R/R)) for whom acalabrutinib in monotherapy was prescribed by treating physician decision no more than 4 weeks ago before screening.

You may qualify if:

  • Age ≥18 years
  • Confirmed diagnosis of CLL
  • Patient started treatment with monotherapy acalabrutinib (prescribed by physician decision no more than 4 weeks ago before screening)
  • Capability of providing written Informed Consent Form

You may not qualify if:

  • Pregnancy
  • Lactation
