Objectives

•評估 nemtabrutinib 併用venetoclax 的安全性和耐受性並確定其劑量。 •由盲性獨立中央審查(BICR)根據 2018 年國際慢性淋巴性白血病工作小組(iwCLL)標準進行評估,比較nemtabrutinib + venetoclax 與 venetoclax 加上rituximab(VR)的無惡化存活期(PFS)。

Test Drug

錠劑

Active Ingredient

Nemtabrutinib (MK-1026; previously known as ARQ 531)

Dosage Form

110

Dosage

5 mg; 20 mg; 45mg

Endpoints

•劑量限制毒性(DLT)
•不良事件(AE)
•因 AE 造成的試驗治療停止
•PFS,定義為從隨機分配至首次記錄疾病惡化或因任何原因死亡的時間,以先發生者為準
