Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After completion of the screening period, eligible participants will be randomized in a 1:1 ratio to each of the following intervention arms:
Arm A: Minimal Residual Disease (MRD)-limited finite AV therapy Arm B: MRD-limited finite VO therapy
The study consists of screening, treatment, and post-intervention follow-up periods. Participants will undergo safety and efficacy assessments during each period for each study arm. The duration of individual participant involvement in the study will be approximately 5 years.
All participants who discontinue study intervention will be followed for safety assessments and survival status. Safety/survival follow-up is not required if the participant permanently discontinues study intervention due to withdrawal of consent, loss to follow-up, or death

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Documented TN CLL/SLL requiring treatment according to iwCLL guidelines 2018 (Hallek et al 2018).
3. Adequate BM function independent of growth factor or platelet transfusion support within 2 weeks of screening initiation as follows:
1. Absolute neutrophil count ≥ 1.0 × 10 9 /L; absolute neutrophil count ≥ 500 cells/μL (≥ 0.50 × 109/L) with documented bone marrow (BM) involvement of chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL).
2. Platelet counts ≥ 30 × 10 9 /L; platelet count ≥ 10 × 10 9 /L in participants with documented BM involvement of CLL/SLL.
4. Estimated CrCL of ≥ 30 mL/min calculated by Cockcroft-Gault (using actual body weight) or serum creatinine \< 2 × ULN,
Males:
CrCL (mL/min) = Weight (kg) × (140 - Age)/72 × serum creatinine (mg/dL)
Females:
CrCL (mL/min) = Weight (kg) × (140 - Age) × 0.85/72 × serum creatinine (mg/dL)
5. Meet the following laboratory parameters (Upper limit of normal (ULN) is based on institutional standards):
1. Serum AST and ALT ≤ 3 × ULN (Higher thresholds may be allowed if hepatic dysfunction is attributable to CLL/SLL and after discussion with the Sponsor Hematology Safety Knowledge Group).
2. Total bilirubin ≤ 1.5 × ULN, unless directly attributable to Gilbert's syndrome.
6. An ECOG (Eastern Cooperative Oncology Group) performance status performance status of 0 to 2 with no deterioration over the previous 2 weeks prior to baseline or day of first dosing.
7. Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (in accordance with national and local patient privacy regulations).
8. Willing and able to participate in all required evaluations and procedures in this study protocol including swallowing capsules and tablets without difficulty.
Exclusion Criteria
2. Clinically significant cardiovascular disease, such as symptomatic arrhythmias, congestive heart failure, or myocardial infarction, within 6 months of screening or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification. Note: Participants with controlled, asymptomatic atrial fibrillation can enroll in the study.
3. Active bleeding or history of bleeding diathesis (eg, hemophilia or von Willebrand disease).
4. Uncontrolled autoimmune hemolytic anemia or idiopathic thrombocytopenic purpura.
5. History of significant cerebrovascular disease/event, including stroke or intracranial hemorrhage, within 6 months before the first dose of study intervention.
6. Child-Pugh B/C liver cirrhosis.
7. History of prior or current malignancy (including but not limited to known central nervous system involvement such as by CLL/SLL, leptomeningeal disease, or spinal cord compression, known prolymphocytic leukemia or history of, or currently suspected, Richter's syndrome) that could affect compliance with the protocol or interpretation of results. Possible examples where compliance or data interpretation may not be affected could include the following, per physician discretion.
1. Curatively treated basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) of the skin or carcinoma in situ of the cervix or carcinoma in situ of the prostate at any time prior to study.
2. Other cancers that have been curatively treated from which the participant is disease-free for ≥ 3 years without further treatment.
8. An individual organ system dysfunction limiting the ability to receive the study intervention or any other life-threatening illness, medical condition, or organ system dysfunction that, in the investigator's opinion, could compromise the participants' safety or interfere with the absorption, distribution, metabolism, or excretion of the study interventions (eg, refractory nausea and vomiting, chronic gastrointestinal disease, inability to swallow the formulated product, previous significant bowel resection, or impaired resorption in the gastrointestinal tract).
9. Known history of infection with HIV or any active significant infection (eg, bacterial, viral, or fungal; including participants with positive cytomegalovirus (CMV) DNA PCR). CMV testing at screening must include serologic testing for CMV immunoglobulin G (CMV IgG), CMV immunoglobulin M (CMV IgM), and CMV DNA PCR testing. Participants must have a result for CMV DNA PCR that is negative at screening to be eligible for the study.
10. History of or ongoing confirmed progressive multifocal leukoencephalopathy (PML).
11. Serologic status reflecting active hepatitis B or C infection:
1. Hepatitis serology will include HBsAg, anti-HBs, anti-HBc and anti-HCV. Any participant who is both anti-HBc positive and HBsAg negative will need to have a negative HBV DNA PCR result before randomization and must be willing to undergo this PCR testing during the study. Any participant who is either HBsAg positive or hepatitis B DNA PCR positive will be excluded.

24. Currently pregnant (confirmed with positive pregnancy test) or breast feeding.
25. Women of childbearing Potential (WOCBP) unless the following criteria are met: A negative pregnancy test at least 30 days before start of study intervention, followed by immediate highly effective contraception; further pregnancy testing will be performed every cycle and as clinically indicated.
26. Fertile men or WOCBP unless the following criteria are met:
1. Female participants (WOCBP): Willing to use highly effective contraceptive method (Pearl Index \< 1 defined as failure rate of less than 1% per year when used correctly and consistently) during study intervention and for 2 days after last acalabrutinib dose, 30 days after last venetoclax dose and 18 months after last obinutuzumab dose whichever is longer.
2. Male participants (fertile; non-sterilized): Male participants with a female partner of childbearing potential must refrain from agree to use a condom with spermicide plus an additional highly effective contraceptive method while on study treatment and 30 days after the last venetoclax dose, and 6 months after the last obinutuzumab dose, whichever is longer. These restrictions apply even if the participant had a vasectomy (condom is still needed to prevent possible direct exposure to a developing baby in case a female partner is already pregnant). Male participants must also not donate sperm during the study and for these same periods of time post-treatment.
