BCL-2 protein overexpression, common in B-cell acute lymphoblastic leukemia (B-ALL), including the Philadelphia (Ph)-like subtype, mediates leukemic cell survival. We treated 24 patients with 14 days of BCL-2 inhibitor, venetoclax, 400 mg daily (dose level 1) during induction and consolidation cycles combined with the CALGB 10403 regimen in newly diagnosed adults with Ph-negative B-ALL. Median age was 31 (range: 18-53) years, 92% were Hispanic, and 12 (50%) patients had Ph-like ALL. No dose limiting toxicity occurred in the phase 1 part. Median times to neutrophil and platelet count recovery were 20 and 21 days from start of induction, respectively. The most common grade ≥3 treatment-related adverse events were leukopenia (96%), neutropenia (83%), anemia (83%), thrombocytopenia (79%), lymphopenia (71%), hyperbilirubinemia (38%), and elevated ALT (33%). One patient with non-Ph-like ALL died from asparaginase-associated pancreatitis, and 23 (96%) patients achieved complete remission (CR) or CR with incomplete count recovery (CRi) following induction with or without extended induction phase. Of 22 patients who started consolidation, 20 (91%) achieved negative minimal residual disease status (MRD-) (.

BCL-2 蛋白过表达常见于 B 细胞急性淋巴细胞白血病 (B-ALL),包括费城 (Ph) 样亚型,介导白血病细胞存活。我们在诱导和巩固周期期间用 14 天的 BCL-2 抑制剂维奈托克每天 400 毫克 (剂量水平 1) 联合 CALGB 10403 方案治疗了 24 例新诊断的 Ph 阴性 B-ALL 成人患者。中位年龄为 31 (范围: 18-53) 岁,92% 为西班牙裔,12 例 (50%) 患者患有 Ph 样 ALL。第 1 阶段部分未发生剂量限制性毒性。中性粒细胞和血小板计数恢复的中位时间分别为诱导开始后 20 天和 21 天。最常见的 ≥3 级治疗相关不良事件是白细胞减少症 (96%) 、中性粒细胞减少症 (83%)、贫血 (83%)、血小板减少症 (79%)、淋巴细胞减少症 (71%)、高胆红素血症 (38%) 和 ALT 升高 (33%)。1 例非 Ph 样 ALL 患者死于天冬酰胺酶相关性胰腺炎,23 例 (96%) 患者在诱导后达到完全缓解 (CR) 或 CR 伴不完全计数恢复 (CRi),有或没有延长诱导期。在开始巩固治疗的 22 例患者中,20 例 (91%) 达到阴性微小残留病状态 (MRD-) (.
