简要总结

To characterize the pharmacokinetics and safety of dabrafenib following a single 100 mg oral dose in subjects with severe renal impairment and end stage renal disease not on dialysis.

详细描述

The main objective of this trial is to evaluate the pharmacokinetics of dabrafenib and metabolites after a single oral dose of dabrafenib in subjects with renal impairment as compared to healthy subjects with normal renal function.

This was a single-dose, open-label, parallel group single dose study to evaluate the pharmacokinetics (PK) and safety of a single oral dose of dabrafenib 100 mg in subjects with severe RI or ESRD compared to matched healthy subjects with normal renal function (control group).

The study consisted of a screening period, a treatment period and a follow-up period.

The Screening period started up to 28 days prior to dosing. Subjects who satisfied the inclusion/exclusion criteria at screening were admitted for baseline evaluations, which was done locally by the investigator. In the treatment period, subjects received a single 100 mg oral dose of dabrafenib administered as two 50 mg capsules with a whole glass of non-carbonated water (approximately 240 mL) in the morning of Day 1 following an overnight fast (minimum 10 hours). Subjects were confined to the study facility from Day -1 to Day 5, for collection of serial blood and urine samples. Subjects were discharged on Day 5.

In the follow-up period a telephone call was made to subjects 30 days post-dose to evaluate subject safety during the weeks after discharge from the facility. Adverse events occurring prior to Day 30 were followed until resolution or until judged to be permanent. Subjects returned to the clinic on Days 90 and 180 for the post-dose dermatological examination follow up.
