Interventions

  • DZD8586+R-CHOP — DRUG
    DZD8586 at the protocol defined dose level (50 mg or 75 mg, po, qd) with R-CHOP (Rituximab: 375 mg/m2, IV, d1; Cyclophosphamide: 750 mg/m2, IV, d1; Doxorubicin: 50 mg/m2, IV, d1; Vincristine: 1.4 mg/m2, IV, d1; Prednisone: 100 mg, po, d1-5) in a 21-day cycle for 6 cycles. DZD8586 (pre-defined dose level, po, qd) as maintenance therapy for CR/PR patients.
  • DZD8586+R-GemOx — DRUG
    DZD8586 at the protocol defined dose level (50 mg or 75 mg, po, qd) with R-GemOx (Rituximab: 375 mg/m2, IV, d1; Gemcitabine: 1000 mg/m2, IV, d1; Oxaliplatin: 100 mg/m2, IV, d1) in a 21-day cycle for 8 cycles. DZD8586 (pre-defined dose level, po, qd) as maintenance therapy for CR/PR patients.
  • DZD8586+BR — DRUG
    DZD8586 at the protocol defined dose level (50 mg or 75 mg, po, qd) with BR (Bendamustine: 90 mg/m2, IV, d1-d2; Rituximab: 375 mg/m2, IV, d1) in a 21-day cycle for 6 cycles. DZD8586 (pre-defined dose level, po, qd) as maintenance therapy for CR/PR patients.

Study Details

This study will treat patients with diffuse large B-cell lymphoma (DLBCL). It will assess the anti-tumor efficacy and safety of DZD8586 combination therapy by using objective response rate and the incidence and severity of adverse events. It will also measure the levels of DZD8586 in the body when combined with immunochemotherapy regimens.

Arms

  • Experimental: DZD8586 combination therapy
    3 cohorts are included in this arm: Cohort 1: Treatment naïve DLBCL patients will receive DZD8586 at the protocol defined dose level, combined with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) regimens for 6 cycles, and then DZD8586 as maintenance therapy for patients who achieved (complete response) CR or (partial response) PR after 6 cycles combination therapy. Cohort 2: Relapsed/refractory DLBCL patients will receive DZD8586 at the protocol defined dose level, combined with R-GemOx (rituximab, gemcitabine, and oxaliplatin) regimens for 8 cycles, and then DZD8586 as maintenance therapy for patients who achieved CR or PR after 8 cycles combination therapy. Cohort 3: Relapsed/refractory DLBCL patients will receive DZD8586 at the protocol defined dose level, combined with BR (bendamustine and rituximab) regimens for 6 cycles, and then DZD8586 as maintenance therapy for patients who achieved CR or PR after 6 cycles combination therapy.
