This is a study of GW274150, an iNOS (inducible nitric oxide synthase) inhibitor to investigate safety, tolerability and pharmacokinetics (PK) in the rheumatoid arthritis (RA) population (greater than 50 years). Safety, tolerability and PK of GW274150 in an adult and elderly population have not yet been determined. Therefore this study is designed to ensure that 90mg GW274150 will be safe and well-tolerated in this adult and elderly RA patient population on methotrexate. The assessments will include pharmacokinetics (PK), liver function tests and creatinine clearance.

This study will provide confidence that a single 90mg dose of GW274150 results in exposure in RA subjects similar to that expected from healthy volunteers and asthmatics.

  • Received their final dose of infliximab or adalimumab within 3 months of enrollment
  • Received their final dose of etanercept or anakinra within 1 month of enrollment
  • Has received an investigational drug or participated in any other NCE research trial within 30 days or 5 half-lives, or twice the duration of the biological effect of any drug (whichever is longer) prior to enrol.ment
