8 History of or ongoing confirmed PML.
9 History of prior malignancy except for the following:
(a) Prior history of malignancy with no evidence of active disease present for more than
3 years before screening or felt to be at low risk for recurrence by treating physician.

adequately resected non-melanomatous skin cancer (ie, basal cell carcinoma or
squamous cell carcinoma of the skin).

gastrointestinal function, or resection of the stomach or small bowel or gastric bypass,
symptomatic inflammatory bowel disease, or partial or complete bowel obstruction.
11 Active uncontrolled systemic infection (bacterial, fungal, viral or other) or clinically
significant localised infection.
12 Known history of infection with human immunodeficiency virus (HIV).
13 Serologic status reflecting active HepB or HepC infection.
(a) Patients with HepB core antibody positive who are surface antigen negative or who
are HepC antibody positive will need to have a negative polymerase chain reaction
(PCR) result before randomisation and must be willing to undergo deoxyribonucleic
acid (DNA) PCR testing during the study.
(b) Patients who are HepB surface antigen positive or HepB PCR positive and those who
are HepC PCR positive will be excluded.
14 History of stroke or intracranial haemorrhage within 6 months prior to randomisation.
15 History of bleeding diathesis (eg, haemophilia, von Willebrand disease).
16 Requires or receiving anticoagulation with warfarin or equivalent vitamin K antagonists
(eg, phenprocoumon) within 7 days of first dose of study treatment. Direct anti-X
(DOACs) or low molecular weight heparins (LMWH, eg, enoxaparin) on stable dosing
schedule is allowed.
17 Requires treatment with a strong cytochrome P450 3A (CYP3A) inhibitor/inducer. The
use of strong CYP3A inhibitors within 1 week or strong CYP3A inducers within 3 weeks
of the first dose of study treatment is prohibited.
18 Breastfeeding or pregnant.
19 Concurrent participation in another therapeutic clinical trial.
20 Uncontrolled cardiac/cardiovascular disease including the following:
- Uncontrolled cardiac tachyarrhythmias (sinus, atrial or ventricular) that require
new/additional therapy within the last month.
- Clinically significant outlying QT interval corrected by Fridericia’s formula (QTcF)
values; QTcF > 470 ms or QTcF < 330 ms.
- Unstable ischaemic heart disease (IHD), recent (< 3 months): episode of acute
coronary syndrome, including acute myocardial infarction and unstable angina
pectoris.
- Percutaneous coronary intervention, or coronary artery bypass graft within the last
month.
21 Uncontrolled hypertension despite optimal management.
22 Current life-threatening illness, medical conditions, organ system dysfunction or lifestyle
habits which, in the investigator’s opinion, could compromise the patient’s safety or
ability to adhere to the study protocol.

Randomised controlled study: Treatment phase: Patients will receive treatment with either acalabrutinib 100 mg po tablets bd (until unacceptable toxicity or progression) or investigator’s choice of treatment (chlorambucil, venetoclax, ibrutinib, zanabrutinib, rituximab or Obinutuzumab etc). For the control arm the treatment type and duration will be defined by the PI prior to randomisation. Each treatment cycle is 28 days/4 weeks. Haematology visits (labs, physical exam), will be performed at the first day of each cycle for the first 8 cycles and every 4 cycles there after. Response assessment will be performed by the PI in accordance with modified iwCLL 2018 criteria every 4 cycles (16 weeks). Imaging and BM testing only as deemed appropriate by PI. Safety assessments will be performed at every visit. Cardiology assessments will be performed at the end of cycle 1 (C2D1) and 3 (C4D1) and thereafter every 4 cycles (16 weeks). These assessments will include: • A cardiology consult. • ECHO, 12-lead ECG and 24-hour Holter. • Cardiac biomarkers. • Any additional testing will be performed as clinically indicated. Cardiac MRI post-screening will be performed every year. Decisions for permanent withdrawal or modifications to treatment due to cardiac AEs will be made by PI after close consultation with the cardiologist. Post-Treatment Phase: Safety assessments Once treatment is discontinued due to any of the reasons mentioned above, a safety follow-up (SFU) will occur within 45 days of the last dose of treatment. This will occur regardless of the patient developing progressive disease or initiation a new anti-CLL therapy during that timespan. The evaluation will include: • Cardiology consult • Cardiac biomarkers • 12-lead ECG, ECHO and 24 hour Holter • Cardiac MRI (if not performed in the last 6 months). The subsequent safety assessments will continue until disease progression, WoC, death or termination of study whichever occurs first. These will mirror the in-treatment schedule, with cardiology consults including ECHO, ECG, cardiac biomarkers and 24 hour Holter performed every 16 weeks and yearly cardiac MRI. Once patient has progressive disease they will be contacted to assess survival status every 16 weeks. Response assessments Patients that discontinue treatment prior to progression will continue to be evaluated for disease progression every 16 weeks. The response assessment will be per iwCLL 2018 guidelines and will be performed by the PI. Bone marrow testing and imaging will continue to remain optional and per PI discretion. Once patient has progressive disease they will be contacted every 16 weeks for survival status and information on any new anti-cancer therapy until WoC, death, termination of study by Sponsor whichever occurs first.
