研究概览
简要总结
The main purpose of this study is to evaluate the effects of repeat dosing of ibrutinib on the single-dose pharmacokinetics (PK) of oral contraceptives (OC - ethinylestradiol [EE] and levonorgestrel [LN]), the cytochrome P450 (CYP)2B6 probe bupropion and the CYP3A4 probe midazolam; and to evaluate the effects of single-dose ibrutinib on the single-dose PK of the CYP3A4 probe midazolam in female participants with B cell malignancy.
详细描述
This is a multicenter study of ibrutinib (first-in-class, potent, covalently-binding inhibitor of Bruton's tyrosine kinase [BTK]) in female participants with B cell malignancy. The study consists of 3 phases: Screening Phase (up to 28 days), 7-day Pretreatment Phase (Days 1 to 7), Treatment Phase including PK assessment period (Days 8 to 26) and a Follow-up Phase (Day 27 to end of Cycle 6). The study procedures includes electrocardiogram (ECG), vital signs, blood samples withdrawal to evaluate PK and safety. The Antitumor activity will be assessed by means of computed tomography (CT) imaging and positron emission tomography (PET) scans. No formal statistical hypothesis will be tested. This is an estimation study designed to determine if an increase or decrease in exposure to OC or probe drugs occurs in the presence of ibrutinib.
