Participant Flow

Subjects were screened and enrolled at 4 sites in the US. Approximately equal number of subjects on 10 mg, 15 mg, 20 mg and 25 mg doses were recruited. The dose group was determined by the Investigator based on subject's current therapeutic regimen of MTX and disease status. The subject's dose was the same for the entire study

MTX was administered via randomized sequence and crossover of Treatment A, Treatment B and Treatment C within the same dose group. Treatments were administered at a 7 day interval (On study days 1, 8 and 15)
