Rheumatology

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.

In a presentation titled “Biosimilar Medicine: Changing Landscape in Health Care,” given on Monday at the 2017 American College of Rheumatology Annual Meeting in San Diego, California, J. Eugene Huffstutter MD, FACP, FACR, shared practical considerations for using biosimilars in the rheumatology clinic.

Three presentations at this week’s 2017 American College of Rheumatology Annual Meeting in San Diego, CA, cover research on pharmacokinetic equivalence, safety, and switching of 2 proposed adalimumab biosimilars, GP2017 and CHS-1420.

Two posters presented today at the American College of Rheumatology’s 2017 meeting in San Diego, California, highlight the gaps in US rheumatologists’ knowledge concerning biosimilar therapies, and underscore the importance of greater physician education about biosimilar medicines.

The Center for Biosimilars® recaps the top 5 stories in biosimilars news for the week of October 30.

As AbbVie’s best-selling Humira faces oncoming biosimilar competition, the drug maker is developing a new innovator product that could help it retain a hold on the market; new results from 3 phase 3 clinical trials show AbbVie’s investigational interleukin-23 inhibitor, risankizumab, to be more effective than adalimumab (Humira) or ustekinumab (Stelara) in patients with moderate-to-severe plaque psoriasis.

Russian biosimilar developer Biocad has won a legal battle that will allow it to move forward with its rituximab biosimilar.

Advances in research suggest that neurotransmitters other than serotonin and noradrenaline may be involved in the pathogenesis and treatment of major depressive disorder, and have pointed to inflammation as an important factor.

Patients with rheumatoid arthritis (RA) have high healthcare utilization and high healthcare costs, which place a burden on health systems and patients alike. However, a recently published retrospective cohort study found that effective treatment for RA (namely, treatment with etanercept) may lead to lower overall and lower RA-related healthcare utilization.

New data from an extension period of a phase 3 study of Samsung Bioepis’ SB2 (Renflexis) in patients with moderate to severe rheumatoid arthritis found that there was no clinically meaningful difference in safety, efficacy, or immunogenicity in patients who were switched from reference infliximab to the biosimilar compared with patients who continued treatment with either the reference or the biosimilar without switching.

A Dutch study reports that 24% of patients who switched from originator infliximab to CT-P13, an infliximab biosimilar, discontinued the biosimilar by their 6-month follow-up, mainly for reasons researchers termed “subjective” health complaints.

Switching patients from originator biologics to biosimilars is associated with the potential for a “nocebo” effect, a phenomenon that occurs when a patient’s negative expectation causes a treatment to have a more negative effect than it otherwise would—essentially, the opposite of the placebo effect.

In recent paper published in Rheumatology, authors Till Uhlig, MD, and Guro L. Goll, PhD explore some of the remaining barriers to the adoption of biosimilar therapies in Europe. Physician attitudes, patient concerns, and prescribing restrictions on biologic therapies are all identified in the paper as having a role curbing uptake of biosimilars.
