New dosing strategy aims to reduce dangerous side effect in blood cancer treatment
NCT ID NCT06697184
First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This study tests new ways to give the drug sonrotoclax to adults with chronic lymphocytic leukemia or mantle cell lymphoma. The goal is to find a dosing schedule that lowers the risk of tumor lysis syndrome, a serious side effect. About 258 participants will be enrolled to check safety and tolerability.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Stable Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 2. 2. Adequate organ function and no very recent transfusion or blood growth factor 3. Participants of childbearing potential must be willing to use a highly effective method of birth control and refrain from egg donation for the duration of the study and for ≥ 7 days after the last dose of sonrotoclax or 1 month after the last dose of zanubrutinib, whichever is later. Only for participants with Chronic Lymphocytic Leukemia (CLL): 4. Confirmed diagnosis of CLL, based on Hallek et al 2018, and requiring treatment due to certain features of their disease 5. At least 1 measurable lesion based on computed tomography (CT)/magnetic resonance imaging (MRI) and no history of prolymphocytic leukemia or Richter's transformation. Only for participants with Mantle cell lymphoma (MCL): 6. Historically confirmed diagnosis of MCL based on the World Health Organization 2022 classification of Haematolymphoid Tumors (WHO-HEAM5) or based on International Consensus Classification (ICC). 7. Relapsed or refractory to the last line of therapy and have received at least 1 prior line of systemic therapy. Note: A line of therapy is considered ≥ 2 consecutive cycles of a systemic anticancer regimen. Patients with prior BTKi therapy should not have progressed during treatment or relapsed within 12 months after BTKi discontinuation. 8. Measurable disease defined as ≥ 1 nodal lesion that is \> 1.5 cm in longest diameter, or ≥ 1 extranodal lesion that is \> 1 cm in longest diameter. Exclusion Criteria: 1. Participants unable to comply with the requirements of the protocol 2. Serologic status reflecting active viral hepatitis B virus (HBV) or hepatitis C virus (HCV) infection 3. Positive HIV serology (HIVAb) status unless certain conditions are met. 4. Participants with any major surgical procedure ≤ 28 days before first dose of study treatment 5. Prior systemic treatment for the CLL 6. Uncontrolled autoimmune hemolytic anemia or immune thrombocytopenia requiring treatment 7. Prior exposure to a BCL-2 inhibitor NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
