Brief summary
A study to assess the real-life management and use of healthcare resources during the initiation of: * Venetoclax in combination with rituximab is indicated for the treatment of adult participants with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy. * Venetoclax in participants with CLL with the deletion of the short arm of chromosome 17 (del\[17p\]) who have received at least 1 prior therapy or participants with CLL without del(17p) who have received at least 1 prior therapy and for whom there are no other available treatment options.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Prophylactic Hospitalization | Up to approximately 6 weeks | Duration of prophylactic hospitalization is defined as the date of discharge - the date of admission + 1. |
| Number of Hours from Dosing to Blood Draw | Baseline (Day 0) | Number of hours between laboratory assessments and the first dose of each ramp-up dose for venetoclax |
| Intravenous (IV) fluid hydration | Up to 24 weeks after first dose of venetoclax | Type of IV fluid participant was on hydration, rate and duration are assessed. |
| Percent of Participants with Tumor Burden of Low, Medium, and High | Baseline (Day 0) | Percent of participants with tumor burden of low, medium, and high. |
| Other Actions Taken within the First 24 Hours of each Dose Ramp-up | Up to approximately 6 weeks | Other actions taken within the first 24 hours of each dose ramp-up, for example, prophylaxis treatment |
| Change from Baseline in Health Care Resource Utilization (HCRU) | Up to 24 weeks after first dose of venetoclax | HCRU will be evaluated using self-administered questionnaire aimed at measuring the patient's health care resource utilization. |
| Change in Metabolites Post Dose | Up to 24 weeks after first dose of venetoclax | Change in metabolites (potassium, creatinine, uric acid, phosphorus, calcium) post dose. |
| Percentage of Participants with Prophylactic Hospitalization | Up to approximately 6 weeks | Percentage of participants with prophylactic hospitalization is defined as the percentage of participants who are hospitalized for prophylactic measures. |
| Reasons for Dose Interruptions | Up to 24 weeks after first dose of venetoclax | Reasons for dose interruptions. |
| Change in Creatinine Clearance | Up to 24 weeks after first dose of venetoclax | Change in creatinine clearance is defined as the change of creatinine clearance from Baseline (Day 0). |
| Number of Hours for Dose Interruptions | Up to 24 weeks after first dose of venetoclax | Number of hours for dose interruptions is defined as the duration of dose interruptions in hours. If more than one does interruption occurs, the total number of hours for dose interruption will be calculated. |
| Number of Weeks for Ramping up Venetoclax Dose to 400 mg daily (QD) or maximum dose reached | Up to approximately 6 weeks | Number of weeks for ramping up to Venetoclax 400 mg QD or maximum dose reached as the duration of the ramping-up period in weeks. |
| Number of Days on Each Dose of Venetoclax | Up to 24 weeks after first dose of venetoclax | Number of days on each dose of venetoclax is defined as the date of first exposure to the dose - the date of the last exposure to the dose + 1. |
Secondary
| Measure | Time frame | Description |
