Researchers want to find better treatments for CLL. To do that, they need to learn how the drug affects CLL cancer cells and the immune system.\n\nObjective:\n\nTo learn about genetic changes that happen during treatment of CLL with venetoclax.\n\nEligibility:\n\nAdults ages 18 and older with relapsed or refractory CLL after at least 1 prior therapy\n\nDesign:\n\nParticipants will be screened under a separate protocol.\n\nIn Phase 1, participants will get venetoclax free of charge through the NIH. Venetoclax is started at a low dose. The dose will be increased every week until participants reach their maximum tolerable dose. This usually take about 5 weeks. Participants will visit the NIH at least once per week. Visits will be about 4 hours. They may have to stay in the hospital to be observed.\n\nIn Phase 2, participants will continue to get the drug through their local cancer doctor and their health insurance. Patients will also visit the NIH every 6 months, or if their disease progresses.\n\nAt the NIH participants will have regular health assessments. These will include physical exams and a review of the medicines they are taking. They will talk about how they are feeling.\n\nThe study included the following tests:\n\nBlood draws\n\nCT scans: Participants will lie in a machine that takes pictures of the body (maximum 3 per year)\n\nBone marrow biopsies: A small amount of marrow will be taken out of the participant s hip bone with a needle.\n\nOptional lymph node biopsies: A small piece of the participant s tissue will be taken out with a needle.\n\nThe study will last at least 2 years.', 'detailedDescription': 'This study aims to study the clonal dynamics and kinetics of response during the ramp-up phase of venetoclax in chronic lymphocytic leukemia (CLL).\n\nKey Eligibility Criteria:\n\n1.

Must have designated hematologist/oncologist who has agreed to assume care and continue venetoclax after the ramp-up phase is complete\n3. Age \\>=18 years\n4. ECOG 0-2\n\nDesign:\n\nPatients with CLL/SLL will enroll on the study. Subjects will be treated at the NIH Clinical Center for the duration of the ramp-up phase of venetoclax. After the ramp-up phase is complete, subjects will be transitioned to the care of their local hematologist/oncologist and receive venetoclax monotherapy or in combination with other agent(s) at the discretion of the treating oncologist. Subjects will have the option to follow-up at the NIH every 6 months (from initiation of venetoclax) and at (suspected) progression.\n\nStudy Objectives:\n\nPrimary Objective:\n\n-Determine the proportion of subjects with clonal shift during the ramp-up phase of venetoclax\n\nSecondary Objective:\n\n-Determine response kinetics of venetoclax therapy in the peripheral blood, lymph nodes and bone marrow\n\nExploratory Objectives:\n\n* Assess relationship between clonal shifts and minimal residual disease (MRD) status, progression free survival (PFS) and overall survival (OS)\n* Assess immunologic changes in the peripheral blood and bone marrow during venetoclax treatment\n* Assess circulating-tumor DNA in response to treatment during venetoclax treatment\n* Compare the proportion of subjects with early clonal shift between patients receiving only venetoclax and patients receiving venetoclax and BTKi overlap during the ramp-up'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': '-INCLUSION CRITERIA:\n\n1.

Any uncontrolled active systemic infection\n3.

Known additional malignancy that is progressing or requires active treatment.\n\n --Note: Exceptions include basal cell carcinoma of skin, squamous cell carcinoma of skin, and in situ cervical cancer that has undergone potentially curative therapy. Further exceptions include other cancers from which the subject has been diseasefree for \\> 2 years, cancers which will not limit survival to \\< 2 years or cancers in remission receiving endocrine therapy.\n5.
