• Adequate bone marrow function:

  1. Absolute neutrophil count (ANC) >1.5 × 109/l (1 × 109/l if due to bone marrow involvement by lymphoma). Patient must not have received any hematologic growth factor within 14 days prior to registration.
  2. Platelet count >100 ×109/l (75 ×109/l if due to bone marrow involvement by lymphoma)

• Adequate hepatic function:

  1. total bilirubin ≤ 1.5 × ULN (except for patients with Gilbert's disease ≤ 3.0 × ULN),
  2. AST and ALT ≤ 2.5 × ULN, or ≤ 5 × ULN under the assumption that abnormal values are tumor related.
• Adequate renal function: estimated glomerular filtration rate (eGFR) ≥ 50 ml/min/1.73 m2 (according to CKD-EPI formula)
• Adequate cardiac function: Left ventricular Ejection Fraction (LVEF) ≥ 50% as determined by echocardiography (ECHO).
• Adequate coagulation function: INR ≤ 1.5 × ULN (the ULN for INR is defined with the value 1.2 for all sites, in case no ULN is documented in the lab certificates/sheets), aPTT ≤ 1.5 × ULN.
• Women of childbearing potential (not surgically sterile or exceeding 2 years after the onset of menopause) must use highly effective contraception, are not pregnant or lactating and agree not to become pregnant during trial treatment and until 3 months after the last dose of investigational drug. A negative pregnancy test before inclusion into the trial is required for all women of childbearing potential.

• Patient is able and willing to swallow trial drug as whole tablet.

Exclusion Criteria:

• Patients with CLL/SLL.

• Concomitant or recent treatment with any other experimental drug (enrollment in another clinical trial.
• Treatment with any anti-lymphoma therapies within 21 days prior to registration - except for local radiation therapy for palliative treatment of symptoms.
• Not resolved grade ≥ 2 (per NCI CTCAE v5.0 toxicity (other than alopecia) from prior therapy at registration.
• Severe or uncontrolled cardiovascular disease (congestive heart failure NYHA III or IV; (see Appendix 4), unstable or new onset angina pectoris, history of myocardial infarction within the last six months, serious arrhythmias requiring medication (with exception of atrial fibrillation or paroxysmal supraventricular tachycardia), significant QT-prolongation.
• Uncontrolled hypertension (sustained systolic blood pressure >150 mmHg and or diastolic >90 mmHg) despite optimal medical management (per investigator's assessment).
• Proteinuria of ≥ CTCAE grade 3 as assessed by a 24h total urine protein quantification or on a random urine sample, estimated by urine protein to creatinine ratio > 3.5.
• HbA1c > 8.5%.
• Lipase ≥ 1.5 x ULN.
• History of cerebrovascular accident or intracranial hemorrhage within 6 months prior to registration.
• Major surgery within 1 month prior to registration.
• Known history of human immunodeficiency virus (HIV) or active chronic Hepatitis C or Hepatitis B Virus infection or any uncontrolled active systemic infection requiring intravenous (iv) antimicrobial treatment. All patients must be screened for HIV up to 28 days prior to study drug start using a blood test for HIV according to local regulations. All patients must be screened for hepatitis up to 28 days prior to study drug start using the routine hepatitis virus laboratory panel. Patients positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) will be eligible if they are negative for HBV-DNA, these patients should receive prophylactic antiviral therapy. Patients positive for anti-HCV antibody will be eligible if they are negative for HCV-RNA.
• Active CMV infection. Patients who are CMV PCR positive at baseline will be excluded.
• Malabsorption syndrome or other condition that precludes enteral route of administration.

• Has active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• Concomitant anticoagulation treatment with warfarin or equivalent vitamin K antagonists (e.g. phenprocoumon), factor Xa inhibitors (e.g. rivaroxaban, apixaban), direct thrombin inhibitors (e.g. dabigatran) or platelet inhibitors/antiplatelet agents. Exception: Aspirin (up to 300 mg/day) is allowed.
