A Polish study of axial spondyloarthritis patients who discontinued treatment with anti–tumor necrosis factor (anti-TNF) therapy because of low disease activity found that more than half eventually needed to restart anti-TNF therapy.

2017 brought a number of notable guests to The Center for Biosimilars®. Here are the most-watched interviews of the year.

The European risk management plan (RMP) contains relevant safety information for specific products, with characterizations of both potential and identified risks, including real-world data. Because the RMP is systematically updated, the RMP can provide early indications of differences in product safety between originator and biosimilar therapies.

AbbVie reported on Wednesday that a phase 3 trial of its upadacitinib as monotherapy for rheumatoid arthritis (RA) met all of its primary and key secondary endpoints, giving more momentum to the drug that appears poised to help AbbVie retain its share of the RA market after adalimumab biosimilars launch in the United States. However, a death reported during the trial raises renewed concerns about the safety of the Janus kinase inhibitor.

Fresenius Kabi, a subsidiary of the German-based Fresenius SE and Co. KFaA, announced yesterday that its Marketing Authorization Application for MSB11022, an adalimumab (Humira) biosimilar candidate, was submitted and accepted for review by the European Medicines Agency (EMA).

Pfizer announced on December 13 that the FDA has approved Ixifi, PF-06438179, infliximab-qbtx, the company’s second biosimilar to the reference infliximab, Remicade.

While the American College of Rheumatology praised the FDA for considering ways to reduce regulatory burden, the organization called on the FDA to focus on 6 “minimum components of review and oversight” for biosimilars.

A recent study was conducted to determine whether the concurrent use of denosumab with a biologic disease-modifying antirheumatic drug (bDMARD), such as adalimuab, etanercept, or infliximab, increases the risk of infection.

Patients with ankylosing spondylitis (AS) may benefit from biologic therapies, including anti–tumor necrosis factor (anti-TNF) treatments including adalimumab (Humira), certolizumab pegol (Cimzia), etanercept (Enbrel), golimumab (Simponi), and infliximab (Remicade or its biosimiars, Inflectra and Renflexis).

A recent case report, published in the European Journal of Rheumatology, showed that switching to biosimilar infliximab resulted in a rapid loss of efficacy in 3 patients with Behçet’s disease (BD), a chronic, relapsing, systemic vasculitis.

A recent Health Technology Assessment (HTA) report by the United Kingdom’s National Institute for Health and Care Excellence (NICE) concludes that adalimumab, etanercept, and ustekinumab improve the symptoms of psoriasis in children and young people in the short term, but the cost-effectiveness of these medications requires further study.

Steinar Madsen, MD, medical director of the Norwegian Medicines Agency, shared lessons learned from the Norwegian experience with biosimilars in a Wednesday talk at the SMi Biosimilars North America conference.

Boehringer Ingelheim (BI) announced today that its adalimumab biosimilar, Cyltezo, has been granted marketing authorization by the European Commission to treat multiple rheumatic diseases after having received a positive opinion from the European Medicines Agency’s Committee for Medicinal Products for Human Use in September 2017.

A recent survey of US rheumatologists found that there is room for improvement in clinicians' awareness of biosimilar therapies.

“If the patient doesn’t have better access, you don’t need a biosimilar," argues Roy Fleischmann, MD.

Chinese researchers employed a new online consultation tool to improve disease management for patients with rheumatic diseases who travel long distances for a consultation with their rheumatologist and noted significant savings for the patients.

Four presentations on Monday at the 2017 American College of Rheumatology’s (ACR) Annual Meeting in San Diego, California, covered research comparing reference etanercept to 4 proposed biosimilars: SB4, LBEC0101, CHS-0214, and GP2015.

At this week’s American College of Rheumatology 2017 Annual Meeting, Boehringer Ingelheim (BI) announced 1-year data from the VOLTAIRE-RA trial, which showed that BI’s newly approved adalimumab biosimilar (Cyltezo) showed no clinically meaningful differences in safety, efficacy, or immunogenicity from the reference adalimumab (Humira) in patients who had moderate to severe rheumatoid arthritis (RA).

Research presented at the 2017 American College of Rheumatology Annual Meeting found that patients with rheumatoid arthritis and higher body mass index were less likely to achieve remission and more likely to face higher rates of disability.

Today, 4 presentations at the 2017 American College of Rheumatology’s (ACR) Annual Meeting in San Diego, California, covered research on switching studies concerning etanercept and infliximab biosimilars.
