Ibrutinib plus venetoclax, given with an ibrutinib lead-in, has shown encouraging clinical activity in early phase studies in mantle cell lymphoma (MCL). The ongoing phase 3 SYMPATICO study evaluates the safety and efficacy of concurrently administered, once-daily, all-oral ibrutinib plus venetoclax in patients with relapsed/refractory MCL. A safety run-in (SRI) cohort was conducted to inform whether an ibrutinib lead-in should be implemented for the randomized portion. Patients received concurrent ibrutinib 560 mg continuously plus venetoclax in a 5-week ramp-up to venetoclax 400 mg for up to 2 years. The primary endpoint was occurrence of tumor lysis syndrome (TLS) and dose-limiting toxicities (DLTs). The SRI cohort enrolled 21 patients; six and 15 were in low- or increased-risk categories for TLS, respectively. During the 5-week venetoclax ramp-up, three patients had DLTs, and one patient at increased risk for TLS had a laboratory TLS; no additional TLS events occurred during follow-up. With a median follow-up of 31 months, the overall response rate was 81% (17/21); 62% (13/21) of patients had a complete response. SRI data informed that the randomized portion should proceed with concurrent ibrutinib plus venetoclax, with no ibrutinib lead-in. Ibrutinib plus venetoclax demonstrated promising efficacy; no new safety signals were observed. Trial registration: ClinicalTrials.gov, NCT03112174.

在复发/难治性套细胞淋巴瘤中同时使用依鲁替尼加 venetoclax:3 期 SYMPATICO 研究的安全性磨合

在套细胞淋巴瘤 (MCL) 的早期研究中,依鲁替尼加 venetoclax 与依鲁替尼导入剂一起给药,已显示出令人鼓舞的临床活性。正在进行的 3 期 SYMPATICO 研究评估了在复发/难治性 MCL 患者中同时给药、每日一次、全口服依鲁替尼加 venetoclax 的安全性和有效性。进行了安全导入 (SRI) 队列以告知是否应该对随机部分实施依鲁替尼导入。患者同时接受 560 mg 依鲁替尼和 venetoclax,为期 5 周,逐渐增加至 venetoclax 400 mg,持续长达 2 年。主要终点是肿瘤溶解综合征 (TLS) 和剂量限制性毒性 (DLT) 的发生。SRI 队列招募了 21 名患者;6 和 15 分别属于 TLS 的低风险或高风险类别。在为期 5 周的 venetoclax 试验期间,三名患者有 DLT,一名 TLS 风险增加的患者有实验室 TLS;随访期间未发生其他 TLS 事件。中位随访 31 个月,总体反应率为 81% (17/21);62% (13/21) 的患者有完全反应。SRI 数据表明,随机部分应同时使用 ibrutinib 加 venetoclax,没有 ibrutinib 导入。依鲁替尼加 venetoclax 显示出有希望的疗效;没有观察到新的安全信号。试验注册:ClinicalTrials.gov,NCT03112174。2017 年 4 月 13 日注册,https://clinicaltrials.gov/ct2/show/NCT03112174。总体响应率为 81% (17/21);62% (13/21) 的患者有完全反应。SRI 数据表明,随机部分应同时使用 ibrutinib 加 venetoclax,没有 ibrutinib 导入。依鲁替尼加 venetoclax 显示出有希望的疗效;没有观察到新的安全信号。试验注册:ClinicalTrials.gov,NCT03112174。2017 年 4 月 13 日注册,https://clinicaltrials.gov/ct2/show/NCT03112174。总体响应率为 81% (17/21);62% (13/21) 的患者有完全反应。SRI 数据表明,随机部分应同时使用 ibrutinib 加 venetoclax,没有 ibrutinib 导入。依鲁替尼加 venetoclax 显示出有希望的疗效;没有观察到新的安全信号。试验注册:ClinicalTrials.gov,NCT03112174。2017 年 4 月 13 日注册,https://clinicaltrials.gov/ct2/show/NCT03112174。
