Radiolabel Study In Healthy Volunteers For Insomnia-Targeting Drug
August 1, 2017 updated by: GlaxoSmithKline
An Open-label Study to Determine the Excretion, Balance and Pharmacokinetics of SB649868 After a Single Oral Administration of 14C-SB649868 in Healthy Volunteers
The purpose of this study is to define the absorption, breakdown and excretion of a single dose of radiolabelled SB-649868 and its breakdown products by measuring their concentration in blood, urine and faeces over a 7-10 day period.
"Radiolabelled" means that the test drug has a radioactive component to help us track the drug.
The safety and tolerability of the test drug will also be assessed.

Description
Inclusion criteria:
- Healthy males, aged 30-55 years inclusive.
- Body weight more or equal to 50kg with a BMI (body mass index) between 18.5-29.9kg/m2 inclusive.
- Healthy as based on a medical evaluation consisting of medical history, physical examination, lab tests on blood and urine and cardiovascular monitoring.
LH, FSH and testosterone hormones must be within normal reference range.
Exclusion criteria:
- Positive urine drug screen or alcohol breath test at screening visit.
- Average weekly alcohol intake of more than 21 units or average daily intake of more than 3 units.
- Grapefruit or grapefruit juice intake 7 days before dosing and until the last blood sample is taken.
- Any subject who is not prepared to eat standard meals in the clinic or is a vegetarian.
- Participated in a clinical trial for a new drug within 30 days or 5 half-lives or twice the duration of that drugs effect before the dosing day for this study.
- Exposure to 4 new drugs in clinical trials within the last 12 months before dosing in this study.
- Use of any medications (prescribed or non-prescribed including vitamins and herbal supplements) within 7 days before dosing in this study.
- Participation in this study would result in the subject donating more than 500ml in a 56 day period.
- Regular use of tobacco or nicotine-containing products within 6 months of screening.
- Unwillingness to abstain from sexual intercourse with pregnant or lactating women from dosing until 84 days after.
- Unwillingness to use contraception and have female partner use contraception if she could become pregnant for 84 days after dosing.
- Unwillingness to abstain from strenuous physical activity for 48 hours before screening and in the 72 hours before and 48 hours after the treatment period.
- Administration of radiolabelled substances or exposure to significant radiation (eg serial X-rays or CT scans, barium meal etc)within the past 12 months from screening.

Experimental: Healthy male subjects
Each subject will receive a single oral dose of 14C-SB649868 (containing approximately 70 microcuries of radiocarbon and 30 milligrams of SB649868).
|
SB-649868 will be provided as powder in a bottle which will be reconstituted into a solution prior to dosing via a hard gelatin capsule.
Each subject will receive one unit dose of SB-649868 30 milligram reconstituted powder presented in a size 00 capsule once.
The capsule will be swallowed with 160 milliliters of water.
