- Meet at least one of the following cardiovascular inclusion criteria: (a) Left ventricular ejection fraction (LVEF) < 50% as assessed by local ECHO at screening. (b) History of heart failure or meeting Universal Definition of Heart Failure at screening (Appendix M), regardless of current LVEF. (c) History of ischaemic heart disease (IHD) including acute coronary syndrome, myocardial infarction, or coronary revascularization (percutaneous coronary intervention/stent or coronary artery bypass surgery). (d) Diagnosis of cardiomyopathy. (e) Ongoing clinically significant (symptomatic or requiring intervention) cardiac arrhythmia, including atrial fibrillation or other arrhythmias. (f) History of moderate or severe cardiac valvular diseases as documented per cardiac imaging.
- Diagnosis of CLL per (Hallek et al, 2018).
- Treatment naïve (TN) or relapsed/refractory (R/R) patients who have received no more than 2 prior lines of systemic anti-CLL treatment.
- Active disease per iwCLL 2018 (Hallek et al, 2018) criteria that requires treatment.
You likely can't join if
- Known active central nervous system (CNS) leukaemia, leptomeningeal disease or spinal cord compression. In case of R/R patients with prior history of CNS localisation of leukaemia who received treatment are eligible provided that there is no evidence of CNS involvement at study entry as documented by CSF cytology and/or brain MRI.
- Breastfeeding or pregnant.
- Concurrent participation in another therapeutic clinical trial.
- Ongoing Richter’s transformation.
- Uncontrolled cardiac/cardiovascular disease including the following: (a) Baseline cardiac troponin (cTnI or cTnT or hs-cTn) levels greater than the upper limit of normal (per the local laboratories reference range) that is due to an acute coronary event and cannot be fully explained by non-ischaemic conditions. (b) Uncontrolled cardiac tachyarrhythmias (sinus, atrial or ventricular) that require new/additional therapy within the last month. (c) Clinically significant QT prolongation defined as QT interval corrected by Fridericia’s formula (QTcF) values; QTcF > 500 ms. (d) Any of the following within the last 3 months: i. Unstable IHD: percutaneous coronary intervention, coronary artery bypass surgery, or an episode of acute coronary syndrome including acute myocardial infarction and unstable angina pectoris. ii. Major cardiac surgery/procedures or valvular surgery. iii. Hospitalization due to heart failure.
- Uncontrolled hypertension (> 140/90 mmHg) despite optimal management.
