Brief summary
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.
Detailed description
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.
Interventions
Ibrutinib capsule (at dose of 420 or 560 mg) will be taken orally QD.
Single dose of oral contraceptives (OC) (1 tablet containing 30 mcg EE and 150 mcg LN) will be taken orally on Study Days 1 and 22.
Bupropion 75 mg tablet as a part of CYP cocktail will be taken on Study Days 3 and 24.
Midazolam 2 mg (1 milliliter \[mL\]) oral solution will be taken on Study Days 3 and 24 (as a part of CYP cocktail) and on Study Day 8 (alone).
