The FDA has approved the Janus kinase (JAK) inhibitor baricitinib (Olumiant – Lilly) for oral treatment of adults with moderately to severely active rheumatoid arthritis (RA) that has not responded adequately to one or more tumor necrosis factor (TNF) inhibitors. Baricitinib is the second JAK inhibitor to be approved for treatment of RA; tofacitinib (Xeljanz, Xeljanz XR) was the first.

Atacept (Orencia - Bristol-Myers Squibb), an inhibitor of T-cell activation, has been approved by the FDA for treatment of moderate to severe rheumatoid arthritis (RA) in patients who have not responded to one or more disease-modifying anti-rheumatic drugs (DMARDs).

The FDA has approved tofacitinib (toe” fa sye’ ti nib; Xeljanz – Pfizer), an oral Janus kinase (JAK) inhibitor, for treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response to or are intolerant of methotrexate. Ruxolitinib (Jakafi) is the only other JAK inhibitor available in the US; it is FDA-approved for treatment of myelofibrosis.

Apremilast (Otezla – Celgene), an oral phosphodiesterase type-4 (PDE4) inhibitor, has been approved by the FDA for treatment of active psoriatic arthritis in adults. It is the fi rst PDE4 inhibitor to be approved for this indication.

Prosorba, an antibody-adsorbing column used with plasmapheresis, has been approved by the FDA for treatment of moderate-to-severe rheumatoid arthritis in patients refractory or intolerant to methotrexate and other disease-modifying anti-rheumatic drugs (DMARDs).

The FDA has approved upadacitinib (Rinvoq – Abbvie), an oral Janus kinase (JAK) inhibitor, for treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response to or cannot tolerate methotrexate (Trexall, and others). Upadacitinib is the third JAK inhibitor to be approved in the US for treatment of RA; tofacitinib (Xeljanz, Xeljanz XR) and baricitinib (Olumiant) were approved earlier.

The FDA has approved a delayed-release oral formulation of prednisone (Rayos – Horizon Pharma). Rayos is not labeled for any specific indication, but the only published studies of the new product have been in patients with rheumatoid arthritis (RA).

Rituximab (Rituxan - Genentech), an anti-CD20 monoclonal antibody already marketed for treatment of B-cell non-Hodgkin's lymphoma, is now FDA-approved for use concurrently with methotrexate to treat moderate to severe rheumatoid arthritis in patients who have had an inadequate response to one or more tumor necrosis factor (TNF) inhibitors. Rituximab selectively depletes CD20+ B cells, which apparently play a role in the autoimmune response and in the chronic synovitis associated with rheumatoid arthritis.

The FDA has approved the interleukin (IL)-6 inhibitor sarilumab (Kevzara – Sanofi) for second-line treatment of adults with moderately to severely active rheumatoid arthritis (RA). It is the second IL-6 inhibitor to be approved for this indication; tocilizumab (Actemra) was approved earlier.
