| A Study in Normal Healthy People, Testing Different Versions of a Pill That Will be Used to Treat Rheumatoid Arthritis.
|
| An Open-Label Two-Part Randomized, Crossover Study Of The Pharmacokinetics Of CE-224,535 Administered As Controlled And Immediate Release Formulations In Healthy Volunteers
|
| The study will try, in 2 separate parts, each using 12 research subjects, to see how a new form of the pill CE 224,535 gets released into the bloodstream and whether that is affected by food. In each part, subjects will switch among 4 treatment periods to take either different forms of the pill(s) or the same form either after fasting or eating a meal. The second part will only happen depending on whether the sponsor believes it is needed and will use separate subject than the first part.
