Participants Receiving Venetoclax
Participants with Chronic Lymphocytic Leukemia (CLL) receiving venetoclax.
- Percentage of Patients Achieving Overall Response Rate (ORR) [ Time Frame: Up to 12 months ]ORR is defined as the percentage of participants achieving partial response (PR) and complete response with incomplete regeneration of bone marrow (CRi) and complete response (CR) according to physician's assessment to therapy with venetoclax.
- Progression-Free Survival (PFS) Rate [ Time Frame: Up to 24 months ]Percentage of patients with PFS where PFS is defined as the number of days from the date of entry in the study to the date of the first documented disease progression, start of a subsequent treatment regimen, or death due to any cause, whichever occurs first.
- Overall Survival (OS) Rate [ Time Frame: Up to 24 months ]Percentage of patients with OS where OS is defined as the number of days from the date of entry in the study to the date of death.
- EORTC QLQ-C30 Scores [ Time Frame: Up to 104 weeks ]European Organization for Research and Treatment of Cancer (EORTC) Quality of Life questionnaire (QLQ) developed to assess the quality of life of cancer patients. and is based on multi‐item and single‐item scales. The core questionnaire contains 5 functional scales, 3 symptom scales, 1 global health status scale, as well as 6 single‐item measures.
- Percentage of Patients Achieving Complete Response with Incomplete Regeneration of Bone Marrow (CRi) [ Time Frame: Up 24 months ]Incomplete regeneration of bone marrow (CRi) as defined in the study protocol.
- European Quality of Life 5 Dimensions (EQ-5D-5L) including visual analogue scale (VAS) [ Time Frame: Up 24 months ]The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life. EQ‐5D‐5L questionnaire consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ‐5D‐5L questionnaire plus a VAS will be used to assess general health in 5 dimensions (mobility, self‐care, usual activities, pain/discomfort anxiety/depression).
- QLQ-CLL 16/17 Scores [ Time Frame: Up to 104 weeks ]Quality of Life Questionnaire - Chronic Lymphocytic Leukemia (QLQ-CLL)16/17 is designed for patients with stage 0 to stage 4 chronic lymphocytic leukemia. It is used to assess 5 domains of health-related quality of life important in CLL: fatigue, side effects and symptoms of disease, infection and social activities or future illness‐related concerns.
- Percentage of Patients with Progressive Disease (PD) [ Time Frame: Up to 24 months ]Progressive disease as defined in the study protocol.
- Percentage of Patients Achieving Partial Response (PR) [ Time Frame: Up to 24 months ]Partial response as defined in the study protocol.
- Percentage of Patients Administering Venetoclax [ Time Frame: Up to 24 months ]Percentage of patients administering venetoclax throughout the study.
- Percentage of Patients with Stable Disease (SD) [ Time Frame: Up to 24 months ]SD is defined as percentage of all patients not having PD, but who do not meet the criteria for PR or CR.
- Percentage of Patients Achieving Complete Response (CR) [ Time Frame: Up to 24 months ]Complete Response as defined in the study protocol.
- Minimal Residual Disease (MRD) measurement on plasma circulating tumor Deoxyribo nucleic acid (DNA) (Switzerland Only) [ Time Frame: Up to 24 months ]MRD is defined as less than 1 clonal lymphocyte per 10000 leukocytes in peripheral blood or bone marrow.
- Clonal evolution and eradication of Tumor Protein p53 (TP53) mutated clones associated with treatment in relation to MRD negativity (Switzerland Only) [ Time Frame: Up to 24 months ]Clonal evolution and eradication of TP53 mutated clones associated with treatment in relation to MRD negativity is evaluated
