The trial is looking for adults whose chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) came back or did not respond, after earlier treatment with a BTK inhibitor and a BCL-2 inhibitor.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Relapsed or refractory CLL or SLL that meets the 2018 iwCLL criteria. People with SLL must have measurable disease on a CT scan, at least 1 lymph node larger than 1.5 cm (0.6 in) in its longest diameter. ECOG performance status of 0 to 2.
Earlier treatment
Must have had a cBTKi, an ncBTKi and a BCL-2i, either in separate lines of treatment or together. Cannot have been treated with a BTK degrader before.

Main reasons for not taking part

  • Known or suspected prolymphocytic leukemia or a more aggressive form, including Richter's transformation
  • Investigational drug or anticancer treatment within 5 half-lives or 14 days (whichever is shorter) before the study drug starts
  • Systemic corticosteroids above 20 mg/day prednisone or equivalent in the 7 days before the study drug
  • Systemic immunosuppressive drugs other than corticosteroids within 60 days before the first dose
  • Earlier treatment with a BTK degrader

The registry criteria, word for word

Who can take part

  • Age: ≥ 18 years
  • Confirmed diagnosis of CLL/SLL that meets iwCLL criteria diagnosis and systemic treatment (Hallek 2018)
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
  • Prior exposure to both a cBTKi, an ncBTKi and a BCL-2i either in separate lines of therapy or in combination
  • Patients with SLL must have measurable disease by computed tomography (CT) per iwCLL. Measurable disease is defined as at least 1 lymph node >1.5 cm in longest diameter and measurable in 2 perpendicular dimensions
  • Adequate organ and bone marrow function

Who cannot take part

  • Known or suspected prolymphocytic leukemia or more aggressive phenotype, including Richter’s transformation, a positron emission tomography (PET) scan should be performed and the treating physician may determine if histopathological evaluation should be performed and results reviewed by the treating physician to rule out transformation prior to enrollment
  • Investigational agent or anticancer therapy within 5 half-lives or 14 days (whichever is shorter) before planned start of study drug
  • Palliative limited-field radiotherapy within 7 days of the first dose of study drug except for broad field radiotherapy (≥30% of bone marrow or whole brain radiotherapy) within 28 days of the first dose of study drug.."
  • Use of systemic corticosteroids >20 mg/day prednisone or equivalent within the 7 days prior to initiation of study drug excepting those used as prophylaxis for radio diagnostic contrast
  • Use of systemic immunosuppressive drugs other than systemic corticosteroids for any medical condition within 60 days prior to first dose of study drug
  • Previously treated with a BTK degrader
