Interventions

  • Sonrotoclax — DRUG
    Participants receive zanubrutinib orally 160mg bid from start of Cycle 1, and in combination with sonrotoclax (SZ) from Cycle 4 onwards at increasing doses until 320mg daily target dose is reached and continuing for at least 12 cycles (each cycle is 28 days). Participants with uMRD and PR/CR by the end of Cycle 15 will stop SZ treatment, others will continue to receive SZ for another 12 cycles and stop SZ if uMRD and PR/CR. Participants will receive sonrotoclax up to 2 years, and receive zanubrutinib for those with MRD-positive by then.

Study Details

This is a single-arm, open-label study of sonrotoclax plus zanubrutinib with MRD-driven treatment duration in patients with previously untreated Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). The primary goal of this study is to evaluate the efficacy of MRD-guided zanubrutinib plus sonrotoclax for first-line CLL/SLL treatment.

Arms

  • Experimental: Sonrotoclax Plus Zanubrutinib
    * Participants will receive from the start of Cycle 1 a standard dose of zanubrutinib twice daily orally for three cycles and in combination with sonrotoclax starting from Cycle 4 onwards at increasing doses twice a week until the target dose is reached from Cycle 5 and continuing until the end of Cycle 15 (each cycle is 28 days). Patients with a measurable minimal residual disease (MRD) will receive another 12 cycles of Zanubrutinib in combination with sonrotoclax until their MRD is undetectable. * Interventions: * Drug: Sonrotoclax * Drug: Zanubrutinib
