Outcomes

Primary Outcome Measures

The primary outcome measure is the values of liver function tests following dosing with methotrexate alone (Day 1) and methotrexate and SB-681323 or placebo (Day 15).

Secondary Outcome Measures

The other comparisons of interest is the pharmacokinetics of methotrexate when dosed alone (Day 1) relative to when dosed with SB681323 (Day 15) pharmacodynamics (effect of SB-681323 on CRP & IL-6 at Days 1, 8 and 15.

5. Study Description

Brief Summary
SB-681323 is a p38 MAP-kinase inhibitor that has potential uses in inflammatory conditions such as RA. Previous p38 MAP-kinase inhibitors have been hindered in development by liver toxicity. Methotrexate (common treatment for RA patients) also has potential liver toxicity. This study was an enabling study to determine the safety of co-administration of the two compounds with respect to liver function
