A Study To Look At The Safety Of SB-681323 In Healthy Adult Subjects After Intravenous Administration Of A Single Dose
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
SB-681323 inhibits the action of an enzyme which is known to contribute to the inflammation seen in such conditions as Chronic Obstructive Pulmonary Disease and Rheumatoid Arthritis. This study will explore the safety of this drug and its blood levels when given in intravenous form to healthy human volunteers.
Safety of SB-681323 in terms of frequency/ nature of adverse events and changes in ECG patterns, vital signs and clinical laboratory parameters (including liver function tests) seen upto 48h after a single intravenous dose.
Secondary Outcome Measures
Regular measurements of SB-681323 blood levels upto 48h after a single intravenous dose. Effects of SB-681323 in blood samples drawn upto 24h after intravenous dosing, on laboratory tests designed to explore the anti-inflammatory properties of the drug.

Exposure prior to the first dosing day to more than 3 new medicinal entities within 12 months or has participated in a study with a new medicinal entity within 3 months or any other study within 2 months.
If participation in the study will result in the subject having donated more than 450 mL blood within a 3 month period.
On physical examination the subject is observed to have poor venous access.
An unwillingness of subjects to abstain from sexual intercourse with women; or unwillingness of the subject to use a condom/spermicide in addition to having their female partner use another form of contraception if the woman could become pregnant from the time of the first dose of investigational product until completion of the follow-up procedures.
