Who cannot take part
Copied verbatim from EU CTIS (euclinicaltrials.eu) and grouped by topic. Only the trial team decides who can take part.
Other illness
- Disease progression during treatment, including transformation to a more aggressive lymphoma
- Occurrence of hypersensitivity symptoms to any of the drugs used or to mouse proteins or to any of the excipients of the drug, preventing continuation of treatment
- Occurrence of progressive multifocal leukoencephalopathy or severe skin reactions (toxic epidermal necrolysis, Stevens-Johnson syndrome) – in case of venetoclax therapy in combination with anti-CD20 antibody
- Uncontrolled autoimmune hemolytic anemia or immune thrombocytopenia – in the case of therapy with venetoclax as monotherapy or in combination with an anti-CD20 monoclonal antibody or ibrutinib
- The occurrence of diseases or conditions which, in the opinion of the attending physician, make further treatment impossible
- Lack of cooperation or failure to follow medical recommendations, including those regarding periodic check-ups to assess the effectiveness and safety of treatment, on the part of the beneficiary or his/her legal guardian
Other
- Occurrence of unacceptable or life-threatening toxicity despite appropriate management
- Pregnancy or breastfeeding
Who the study is looking for
- Age > 18 years
- Exclusion of pregnancy and breastfeeding
- Patient consent to contraception in accordance with the relevant, current Summary of Product Characteristics
- Absence of active, severe infections
- Absence of significant comorbidities or clinical conditions constituting a contraindication to therapy, as determined by the attending physician based on the relevant, current Summary of Product Characteristics
- Adequate organ function, determined on the basis of laboratory blood test results, enabling, in the opinion of the attending physician, safe commencement of therapy
- Prior treatment for CLL or SLL, including chemotherapy, BTK inhibitor therapy, venetoclax, small molecule signaling inhibitor, or monoclonal antibody therapy with response to previous venetoclax treatment > 36 months from last dose
- Adequate hematologic function independent of growth factors or transfusion support, according to the local laboratory reference range at screening (unless due to underlying disease, as evidenced by extensive bone marrow involvement or hypersplenism secondary to splenic lymphoma according to the investigator), defined as follows: • Hemoglobin ≥ 9 g/dL • Absolute neutrophil count ≥ 1.0 × 109/L • Platelet count ≥ 75 × 109/L
- Adequate renal function, according to the local laboratory reference range at screening, as indicated by: Calculated creatinine clearance ≥ 30 mL/min/1.73 m² using 24-hour creatinine clearance or the modified Cockcroft-Gault equation (eCCR; using ideal body weight [IBM] instead of weight)
- Normal liver function, according to the local laboratory reference range for screening, as indicated by: • AST and ALT ≤ 2.5 × ULN • Total bilirubin ≤ 1.5 × ULN (or ≤ 3 × ULN in patients with documented Gilbert's syndrome)
- Absence of active hemolytic anemia requiring immunosuppressive or other pharmacological treatment. Patients with a positive Coombs test but no evidence of hemolysis are NOT excluded from participation in the study
- Obtaining the patient's informed voluntary consent to participate in the study
- No current use of corticosteroids. EXCEPTION: Low-dose steroids (<10 mg prednisone or equivalent dose of another steroid) are permitted for the treatment of non-hematological conditions (e.g., chronic adrenal insufficiency)
- No prior autoimmune complications (e.g., autoimmune hemolytic anemia or immune thrombocytopenia) that have developed since the initial diagnosis of CLL and required treatment with high-dose corticosteroids (e.g., equivalent to >20 mg prednisone daily), monoclonal antibody-based therapy, or chemotherapy. Previous use of corticosteroids for reasons other than the treatment of autoimmune complications of CLL is permitted
- No major surgery within 4 weeks (28 days) of the first dose of study drug or minor surgery within 3 days of the first dose of study drug
- No radiotherapy ≤ 4 weeks before starting study treatment
- The patient must be able to take a xanthine oxidase inhibitor or rasburicase for tumor lysis syndrome (TLS) prophylaxis
- Negative pregnancy test result (serum βHCG concentration) for women of reproductive age (including premenopausal women who have had tubal ligation) and for all women who do not meet the definition of postmenopausal (≥ 24 months of amenorrhea) and who have not undergone surgical sterilization through hysterectomy and/or bilateral oophorectomy. For all other women, documentation confirming that the patient is not of reproductive age should be provided in the medical interview. ● Patients who are not surgically sterile or postmenopausal must agree to the simultaneous use of two reliable forms of contraception or to complete abstinence from heterosexual intercourse during the study. ● Men must agree to use a latex condom during sexual contact with women of reproductive age during the study and for at least 28 days after discontinuing the study, even if they have had a successful vasectomy
- Ability and willingness to comply with the requirements of the study protocol
