This study is a Phase 1b proof-of-concept, open-label study to assess the safety and pilot efficacy of Enbrel administered by the Sofusa® DoseConnect™ delivery system (SOFUSA) for the treatment of patients with moderately to severe RA and an inadequate response to subcutaneous (SC) Enbrel. SOFUSA Enbrel will be administered once weekly to patients for 12 weeks. Patients will start on an Enbrel dose of 25 mg during the induction phase of the study and may be increased to an Enbrel dose of 50 mg during the dose escalation phase of the study based on the dose escalation criteria. Patients will remain on either the 25 mg or 50 mg dose for the final maintenance phase of the study.
This is an open-label pilot study in patients with rheumatoid arthritis (RA). All patients will receive SOFUSA Enbrel 25 mg once weekly. The dose will be increased to 50 mg if the dose escalation criteria are met during the dose escalation phase of the study.
