About

The goal of this prospective single-arm open-label trial is to learn about efficacy and safety of Bortezomib in treating patients with difficult-to-treat rheumatoid arthritis. The main questions it aims to answer are:

Is Bortezomib an effective treatment option for patients with difficult-to-treat rheumatoid arthritis?
Is Bortezomib safe enough in treating patients with difficult-to-treat rheumatoid arthritis?

Participants will:

Receive Bortezomib 2 mg per week subcutaneously for twelve weeks in total.
Follow-up at weeks 4, 12, and 24, while biosamples will be collected.
