Novartis announced on Thursday that the FDA has approved a label update for secukinumab (Cosentyx) to include moderate to severe scalp psoriasis, a particularly challenging form of psoriasis to treat, and a condition that affects approximately half of patients with psoriasis.

The Center for Biosimilars recaps the top 5 biosimilars articles for the week of February 5, 2018.

In late 2017, a study was published in Acta Reumatologica Portuguesa evaluating the effect adalimumab (Humira), an anti–tumor necrosis factor therapy in the treatment of patients with both short- and long-term psoriatic arthritis (PsA) disease duration.

The American College of Rheumatology (ACR)'s previous position on biosimilars was one of caution during the initial development, evaluation, and approval of these drugs, but, writes the organization, “Now that biosimilars have been used successfully in Europe, with rigorously acquired data supporting their broader use, and as the [United States] is on the verge of a similar transition, the ACR is poised to reconsider its position.”

Managed care professionals can assist ophthalmologists and retina specialists in personalizing anti-vascular endothelial growth factor (anti-VEGF) treatment to encourage patient adherence, according to a recent review of the literature on this topic.

Because serum tumor necrosis factor (TNF) is high in patients with Kawasaki disease (KD), infliximab, an anti-TNF agent, has been proposed as a potential treatment for refractory KD, but few randomized trials have been conducted to demonstrate the efficacy and safety of using infliximab in this setting.

A cross-sectional study published in the International Journal of Clinical Pharmacy in late 2017 found that the uptake of biosimilars in the United Kingdom has been highly variable and generally lower than expected.

The early weeks of 2018 held substantial developments for oncology biosimilars in the United States and around the world, with new products on the horizon and evolving challenges in bringing these drugs to the marketplace.

During the American College of Rheumatology's (ACR) Winter Rheumatology Symposium last week in Snowmass, Colorado, one of the sessions comprised a panel addressing treatment options for inflammatory arthritis. One case study the panel addressed the pros and cons of dose reduction versus an increase in dosing interval of a biologic for a patient with rheumatoid arthritis (RA) who has achieved low disease activity or remission.

A recent study, set in the Netherlands, sought to assess patients’ attitudes about redistributing unused, subcutaneously administered biologic drugs, which could allow potential cost savings for the health system. However, the study unexpectedly found alarming storage inconsistencies and patient nonadherence to storage guidelines for these drugs.

Rituximab has been successfully used “off label” to treat diseases driven by B-cell dysregulation, but concerns remain about the safety of using rituximab or similar agents for long periods.

Zarxio, a biosimilar filgrastim approved in the United States in 2015, was demonstrated to have no clinically meaningful differences from its reference in a randomized clinical trial setting, but data on its effectiveness in preventing febrile neutropenia (FN) a real-world setting have been limited thus far.

Although some studies have demonstrated an increased risk of death in patients with inflammatory bowel disease taking corticosteroids, the relationship between death and anti–tumor necrosis factor (anti-TNF) drugs has not been as clear.

At the American College of Rheumatology (ACR)'s Winter Rheumatology Symposium, held this week in Snowmass Village, Colorado, rheumatologists from across the country gathered to discuss the latest approaches to treating rheumatoid arthritis (RA).

In an observational study conducted in Germany that began after the marketing authorization was received for reference trastuzumab in early breast cancer (EBC), researchers were able to analyze outcomes for patients treated with trastuzumab both with and without cytotoxic treatment.

SAR342434, or Admelog, a follow-on of insulin lispro (Humalog), showed similar efficacy, safety, and immunogenicity to its reference in patients with type 2 diabetes who also used insulin glargine (Lantus) as basal insulin, according to the results of the SORELLA-2 study, published in the January 2018 issue of Diabetes Technology & Therapeutics.

Some data that physicians would like to see demonstrated in bioequivalence studies may not be feasible in clinical trials due to the number of patients who would have to be enrolled in the studies.

Targeting sustained and stringently defined clinical remission in patients with moderately active rheumatoid arthritis (RA) receiving full-dose combination therapy with etanercept plus methotrexate before considering dose or regimen changes may help improve the likelihood that patients will remain in clinical remission 1 year after the changes are made.

Antagonism of tumor necrosis factor-alpha (TNF-alpha) may be a good treatment strategy to counter the deleterious effects of TNF-alpha on the development of insulin resistance and the pathogenesis of type 2 diabetes.

An editorial, recently published in Annals of the Rheumatic Diseases, discussed the results of a study that found that an adalimumab (Humira) concentration-based tapering strategy was not inferior to the conservative strategy, conducted over 26 weeks.

In an expert review, the authors provide transparency about biosimilar production, approvals, risk, and benefits to help improve confidence that the same safety and efficacy can be expected from biologics and their biosimilars.

A newly published retrospective study found that patients who received a combination therapy with infliximab and azathioprine early on had significantly increased linear growth compared to patients whose therapy was stepped up.

A recent research letter, published in the British Journal of Dermatology, reports that a biosimilar of etanercept, SB4 (approved as Benepali in the European Union and Brenzys in The Republic of Korea, Canada, and Australia), is associated with fewer injection-site reactions and less immunogenicity than reference etanercept (Enbrel), while maintaining equivalent efficacy.

Rituximab is approved for use in hematological malignancies and in rheumatoid arthritis (RA), but is also used off-label in the treatment of antibody-dependent auto-immunological diseases. In off-label indications, alternative dosing schedules are sometimes used, though no dose-finding trials are available to help guide dosing in such diseases.

Patients with rheumatoid arthritis (RA) who require a change in therapy from anti–tumor necrosis factor inhibitor (anti-TNF) treatments to biologics with a different mechanism of action (MOA) had higher treatment persistence and lower healthcare costs than patients who cycled anti-TNF drugs, resulting in lower healthcare costs per persistent patient among the MOA switchers, a recent study finds.

In an editorial that was recently published in Alimentary Pharmacology and Therapeutics, authors D. Sawbridge, MD, and S. Subramanian, MD, discussed how to mitigate primary nonresponse to infliximab.

Rituximab (Rituxan) is more effective and has lower rates of discontinuation than other disease-modifying treatments in newly diagnosed patients with relapsing-remitting multiple sclerosis, according to a Swedish study published online in the January 8, 2018, issue of JAMA Neurology.

Intravitreal injection of bevacizumab (Avastin) has revolutionized the treatment of diabetic eye disease, and has emerged as an important treatment modality, either as primary or adjuvant therapy for diabetic macular edema and proliferative diabetic retinopathy.

While the European experience with biosimilars is one of significant uptake of biosimilars, individual European nations have had distinctly different levels of uptake. These differences are largely due to local variation in pricing and reimbursement, education levels, population characteristics, and stakeholder incentives.
