Study to Assess the Safety and Efficacy of Enbrel Administered by Sofusa DoseConnect for Rheumatoid Arthritis

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.

Purpose of Study

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.

Is currently on Enbrel therapy and has received once-weekly Enbrel injections for at least 12 weeks with no more than 1 missed dose in the 12 weeks prior to Screening.
Must meet the following disease criteria:

Have a DAS28(CRP) score > 2.9 at Screening Have a DAS28(ESR) score > 3.2 at Screening Swollen joint count ≥ 3 (28-joint count) and Tender joint count ≥ 3 (28-joint count) at Screening and Baseline

If on oral or subcutaneous MTX (up to 25 mg/week) or other permitted oral conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) (i.e., leflunomide, up to 20 mg/day; hydroxychloroquine, up to 400 mg/day; or sulfasalazine, up to 3 g/day), must be on stable dose (MTX ≥ 12 weeks and other permitted DMARDs ≥ 8 weeks) within the specified ranges prior to Baseline. Note: if on methotrexate (MTX), subjects must be on a stable dose of folic acid (total ≥ 5 mg per week for ≥ 12 weeks) prior to Baseline and must continue a stable dose during the course of the study.
If taking regular nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase-2 (COX-2) inhibitors, paracetamol/acetaminophen, or oral glucocorticoids for treatment of RA symptoms, must be on stable dose and route of administration for at least 2 weeks before Baseline
Females of childbearing potential must agree to use acceptable method(s) of contraception for the duration of the study and for 3 months after the last dose of study drug

Exclusion

Exclusion Criteria:

Prior treatment with investigational therapy within 30 days or 5 half-lives before Screening (whichever is longer)
History of hypersensitivity to any recombinant protein drugs or any of the excipients used in Enbrel
Has skin contact sensitivities (due to SOFUSA device adhesive) or allergies to iodine (due to the iodine in ICG)
Lack of any clinical response to Enbrel in the Investigator’s opinion
Treatment with other biologic agents (e.g., interleukin [IL] 6, IL17, IL12/23 inhibitors; abatacept, tumor necrosis factor [TNF] inhibitors) besides Enbrel within 24 weeks before Baseline

Use of chlorambucil or cyclophosphamide within 24 weeks of Baseline
Use of leflunomide within 8 weeks of Baseline, if washing out of leflunomide, unless a cholestyramine washout has been performed, then use of leflunomide within 4 weeks of Baseline
Use of MTX, hydroxychloroquine, or sulfasalazine within 4 weeks of Baseline, if washing out of MTX, hydroxychloroquine, or sulfasalazine
Any systemic nonbiologic DMARD (e.g., Janus kinase inhibitor, cyclosporine, azathioprine) within 4 weeks of Baseline

Use of intramuscular, intravenous, or intraarticular corticosteroid therapy within 4 weeks prior to Baseline
Treatment with any intra-articular hyaluronic acid preparation within 12 weeks prior to Baseline
Chronic arthritis diagnosis before the age of 17 years
Presence of any extra-articular manifestations of RA, except for rheumatoid nodules
Joint surgery within the preceding 8 weeks before Screening
