Participant Flow

Subjects were screened and enrolled at 2 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 patient's dose was the same for the entire study.

The order of Methotrexate (MTX) treatment arms (A-SC injection with Vibex-MTX device, B-SC injection without device and C-IM Injection) were randomly assigned and dosing was separated by interval of atleast 7 days to allow for washout before the next treatment was administered.
