JAMA has an article this week on the shift from biologic drugs to less expensive therapeutic biosimilar agents. The impact of biosimilars can be easily represented by the shift from adalimuamb - a biologic with nearly $19 billion in sales in 2018 - to any one of the four FDA approved biosimilars for adalimumab (see the daily download for slides on new adalimumab and other biosimilars).

The SEAM-PsA study examined the efficacy of methotrexate monotherapy, etanercept monotherapy or the combination of MTX and ETN in psoriatic arthritis patients, and found that ETN monotherapy was equivalent to combination therapy - and that both were superior to MTX alone in clinical (ACR and MDA) and radiographic responses.

The European Medicines Agency safety committee (PRAC) has concluded that Xeljanz (tofacitinib - TOFA) could increase the risk of blood clots in the lungs and in deep veins in patients who are already at high risk for venous thromboembolic events. The PRAC is recommending that TOFA should be used with caution in patients at high risk of blood clots (VTE), regardless of dose used.

The American College of Rheumatology (ACR), in partnership with the Spondylitis Association of America (SAA) and the Spondyloarthritis Research and Treatment Network (SPARTAN), released the 2019 Update of the Recommendations for the Treatment of Ankylosing Spondylitis (AS) and Nonradiographic Axial Spondyloarthritis (nr-axSpA).

It’s hard work wearing a crown. The dermatologists have been dethroned as Medscape’s happiest specialty after years at the top. While studies only detail that we are the most satisfied outside of work, I argue we are the happiest working, too. With an N of 1, here are my 10 observations.

The US Food and Drug Administration (FDA) on Friday, August 16, approved AbbVie JAK1 inhibitor, Rinvoq (upadacitinib) for adults with  rheumatoid arthritis with moderately to severely active disease either not responding to, or intolerant of, methotrexate (MTX). 

A EULAR task force has reviewed the medical literature and developed evidence-based recommendations for the management of antiphospholipid syndrome (APS) in adults. They note that a high-risk antiphospholipid antibody (aPL) profile is associated with greater risk for thrombotic and obstetric APS.

The European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) have jointly developed new classification criteria for systemic lupus erythematosus (SLE); prompted by the need for criteria that were both highly sensitive and specific. The net result is improved sensitivity and specificity, but the use of positive ANA requirement along with a longer list of weighted criteria ensures its utility in SLE research (
