Inclusion criteria
* Participants with diagnosed Chronic Lymphocytic Leukemia (CLL) and eligible for venetoclax as per label. * Participants for whom the physician has decided to initiate CLL treatment with venetoclax. * Participants who have been informed verbally and in writing about this study, and who do not object to their data being processed or subjected to data quality control.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Response Rate (ORR) | Up to approximately 12 months | ORR to treatment is defined as the proportion of patients with complete response (CR), Complete Response with incomplete bone marrow recovery (CRi), nodular Partial Response (nPR) and partial response (PR), according to physician's assessment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complete Response (CR) Rate | Up to approximately 24 months | CR is defined as the proportion of participants with either CR and CRi, according to physician's assessment. |
| Time to Response (TTR) | Up to approximately 24 months | TTR is defined by the time between the date of the first venetoclax intake and the date of the first assessment having documented the response among complete response, complete response with incomplete bone marrow recovery, nodular partial response, and partial response. |
| Time to Best Response to Treatment | Up to approximately 24 months | The time to best response to treatment is defined by the time between the date of the first venetoclax intake and the date of the assessment having documented the best response among CR, CRi, nPR, and PR. |
| Overall Survival (OS) | Up to approximately 48 months | Overall survival (OS) is defined as the time from the date of first venetoclax intake to the date of death from any cause. |
| Time To Progression (TTP) | Up to approximately 48 months | The Time To Progression (TTP) is defined as the time from the date of first venetoclax intake to the date of the first documented disease progression. |
| Progression-Free Survival (PFS) | Up to approximately 48 months | PFS is defined as the time from the date of first venetoclax intake to the date of the first documented disease progression or death from any cause. |
| Overall Response Rate (ORR) | Up to approximately 24 months | ORR to treatment is defined as the proportion of patients with complete response (CR), Complete Response with incomplete bone marrow recovery (CRi), nodular Partial Response (nPR) or partial response (PR), according to physician's assessment. |
| Duration of Response (DOR) | Up to approximately 48 months | DOR is calculated in the sub-population of patients experiencing treatment response (complete response, complete response with incomplete bone marrow recovery, nodular partial response or partial response) from the date when response is first met to the date of first following documented progression. |
| PFS after Disease Progression Following Venetoclax Treatment | Up to approximately 48 months | PFS following venetoclax treatment is defined as the time from the date of first next CLL treatment intake to the date of the following documented progression or death from any cause. |
| Best Response under Next CLL Treatment | Up to approximately 48 months | The best response under next CLL treatment is calculated in the sub-population of participants having a next CLL treatment after venetoclax discontinuation. |
| Minimal Residual Disease | Up to approximately 24 months | The proportion of participants with assessment of the minimal residual disease under venetoclax treatment (assessed by flow cytometry or Polymerase Chain Reaction). |
| Change in Score of EuroQol 5 Dimensions (EQ-5D-5L) | Up to approximately 24 months | The EQ-5D-5L has five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. These dimensions are measured on a five-level scale: no problems, slight problems, moderate problems, severe problems, and extreme problems. The scores for the 5 dimensions are used to compute a single utility index score ranging from zero (0.0) to 1 (1.0) representing the general health status of the individual. The EQ-5D-5L also contains a visual analog scale (VAS) to assess the subject's overall health. |
| Time To Next Treatment | Up to approximately 48 months | Time to next treatment is defined as the time between the date of the first venetoclax intake and the date of the first next treatment intake after venetoclax discontinuation. |
