Absolute BA and OZ439 PK Effect of Different OZ439 Dose Volumes and Cobicistat Co-administration Study
An Open-label, Two-part Study to Determine the Absolute Bioavailability (BA) of OZ439 Using Simultaneous Intravenous [14C]-OZ439 Microdose/800mg Oral Dosing and to Investigate the Pharmacokinetics (PK) of OZ439 Granules Administered as Single Doses Suspended in Different Volumes and When Co-administered With a Single Dose of Cobicistat, a Strong CYP3A4 Inhibitor, to Healthy Subjects in Fasted State

Gedetailleerde beschrijving
Primary objectives of this study are:
- to determine the absolute bioavailability of OZ439 following a single oral dose of OZ439 dispersion and a simultaneous single intravenous (iv) microdose (100 μg) infusion of [14C]-OZ439 under fasted conditions (Part 1)
- To evaluate the effects of a single oral dose of cobicistat, a strong cytochrome P450 (CYP) 3A4 inhibitor, on the pharmacokinetic (PK) profile of a single oral dose of a dispersion of OZ439 simple granules under fasted conditions (Part 2)
- To evaluate the PK of single doses of OZ439 granules when restricting the target dosing volumes to 64.5 or 100 mL (Parts 1 and 2)
Secondary objectives are:
- To assess the safety and tolerability of OZ439 when administered alone, and to assess the safety and tolerability of OZ439 and cobicistat when co-administered as single doses to healthy subjects (Parts 1 and 2)
- To determine the PK parameters of OZ439 single iv microdose (100 μg) infusion of [14C]-OZ439 (Part 1)
- To assess the effects of the total dosing volume and of dose to volume ratio on OZ439 PK under fasted conditions (Parts 1 and 2)
- To determine the PK parameters and exposures of cobicistat (Part 2)

As all female subjects must be of non-childbearing potential, they are not required to use any contraception during this study.
- Male subjects must use adequate contraception and not donate sperm from (first) admission to the clinical research center until 90 days after the follow-up visit. Adequate contraception for the male subject (and his female partner) is defined as surgical sterilization (vasectomy), using hormonal contraceptives (implantable, patch, oral, injectable) or an intrauterine device or system combined with at least 1 of the following forms of contraception (barrier method): a diaphragm or cervical cap, or a condom. Also, total abstinence, in accordance with the lifestyle of the subject is acceptable.
- Must have QTcF ≤450 ms and QTcB ≤450 ms (male subjects); QTcF ≤470 ms and QTcB ≤470 ms (female subjects), and PR-interval ≤200 ms for screening, and Day -1 and pre-dose ECG measurements of the (first) treatment period

- History of post-antibiotic colitis

- Use of moderate/strong inhibitors or inducers of CYP cytochromes or transporters within 30 days or 5 half-lives (whichever is longer) prior to the first dose of study drug
- Consumption of grapefruit, grapefruit juice or grapefruit-related citrus fruits (e.g. Seville oranges, pomelos) within 14 days prior to the first dose of study drug
- Use of prescription or non-prescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study drug. With the exception of paracetamol (which may be used incidentally or for a short-term treatment at a maximum dose of 2 g per day) and hormone replacement therapy
- Use of herbal supplements within 30 days prior to the first dose of study drug
- Positive hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody or HIV-1 or HIV-2 antibody results
- Clinically significant abnormal biochemistry, hematology or urinalysis as judged by the PI. In case of doubt the PI will discuss this with the medical monitor
- Positive urine drug screen result at screening or admission to the clinical research center
- Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients
- Presence or history of allergy requiring treatment. Hayfever is allowed unless it is active
- Donation or loss of >100 mL of blood within 90 days prior to drug administration
- Regular alcohol consumption in males >21 units per week and females >14 units per week (1 unit = 250 mL beer, 25 mL of 40% spirit or 125 mL of wine)
- Subjects who do not have suitable veins for multiple venepunctures/cannulation as assessed by the PI or delegate at screening
- Failure to satisfy the PI of fitness to participate for any other reason

Experimenteel: Part 1, single arm
This was an open-label study in 8 healthy subjects to determine the absolute bioavailability of OZ439 following a single oral dose of OZ439 and co-administration of a single iv infusion of a [14C]-OZ439 radiolabeled microdose at the anticipated Tmax of the oral dose. Subjects received the following treatment: Treatment A: A single oral dose of 800 mg OZ439 simple granules administered as a 100-mL dispersion followed by a 15-minute 10-mL iv infusion of 100 μg [14C]-OZ439 (47 kBq [1.27 μCi]) beginning 3 hours after the oral dose administration. |
