Improvements in biosimilars—ones that may give them an advantage such as lower immunogenicity or a new route of administration—may be the key to unlocking a better patient experience, according to Celltrion. In fact, pursuing such so-called “biobetters” may prove to be more important for the drug maker than pursuing interchangeable biosimilars.

Postmarket drug price changes alone accounted for most of the recent spending growth on biologics, and manufacturers’ rebates had little impact, according to an abstract presented at the American College of Rheumatology’s 2019 meeting, being held in Atlanta, Georgia, this week.

Over the past few years, awareness of biosimilars has been increasing; however, research presented at the American College of Rheumatology’s 2019 meeting, being held in Atlanta, Georgia, shows that while US rheumatologists hold growing awareness of biosimilars, hesitancy remains around such issues as switching stable patients and the extrapolation of indications.

On Sunday, during the American College of Rheumatology (ACR)’s 2019 meeting, being held in Atlanta, Georgia, researchers reported on the safety and efficacy of the proposed infliximab biosimilar ABP 710 in a phase 3 study of patients with rheumatoid arthritis (RA). Researchers also reported on a phase 1 and 3 study of the proposed rituximab biosimilar, ABP 798, in patients with RA.

A recent study from Romania examined the efficacy and safety of biosimilar etanercept SB4 (Benepali) compared to originator etanercept in a real-life cohort of patients with rheumatoid arthritis (RA).

Novartis Friday announced results from a head-to-head trial of its secukinumab (Cosentyx) versus adalimumab in patients with active psoriatic arthritis (PsA), saying its therapy missed statistical significance for its primary end point.

Researchers reported on 1-year follow-up among patients at 2 centers, all of whom had psoriasis or psoriatic arthritis, after Brazilian health authorities issued a 2017 mandate that patients being treated with the reference infliximab be switched to CT-P13, and that new starts be given the biosimilar instead of the reference.

The Japanese Adverse Drug Event Report (JADER) database, a large, published database managed by the Pharmaceuticals and Medical Devices Agency for pharmacovigilance, collects spontaneous reports as a means to detect adverse events (AEs) related to drugs, and a newly published study used the JADER data to assess AEs related to the reference infliximab and to the biosimilar, CT-P13.

The Institute for Clinical and Economic Review (ICER), a nonprofit health technology assessment body, has issued an updated report on treatments for rheumatoid arthritis (RA) in which it says that the Janus kinase (JAK) inhibitor upadacitinib has a marginal clinical benefit over adalimumab and an "incremental cost-utility ratio falling below commonly cited thresholds.”

In treating patients with moderate to severe psoriasis, Samsung Bioepis’ etanercept biosimilar, approved in the European Union as Benepali and in the United States as Eticovo, was shown to be effective in a registry study.

A recent preliminary study examined whether adults treated with anti–tumor necrosis factor agents (anti-TNFs) had reduced the risk of Alzheimer disease, and found that patients with rheumatoid arthritis (RA) and psoriasis who were treated with anti-TNFs had a lower risk of developing the incurable neurocognitive disorder.

According to the authors, while many anticipated that most major concerns about the switch to biosimilar adalimumab would relate to safety and efficacy, more prevalent concerns were related to device type, the presence of a citrate, or the color of the product.

The FDA has approved Pfenex’s follow-on teriparatide, PF708, referencing Forteo, for the treatment of osteoporosis in patients at high risk for fractures.

Could adalimumab and its biosimilars become a less attractive option for treating some inflammatory diseases in the face of new therapeutic choices like interleukin-17 inhibitors? In the case of ixekizumab, a recent head-to-head study versus adalimumab showed that the newer product was superior in terms of improving joint and skin disease in patients with psoriatic arthritis.

Drug maker Novartis announced that it will seek a fourth indication—nonradiographic axial spondyloarthritis (nr-axSpA)—for its secukinumab (Cosentyx) in the United States after its phase 3 PREVENT trial met its 52-week primary end point.

The FDA has approved another indication for reference rituximab (Rituxan), this time for children with rare vasculitis diseases.

The bill would amend the Employee Retirement Income Security Act to require group health plans to provide an exception process for step therapy so that patients can access treatment without delays.

A report out this week from the House Ways and Means Committee details the extent to which Americans pay more for drugs than other countries—nearly 4 times as much, in fact.

During its September 2019 meeting, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion recommending a change to Celltrion’s marketing authorization for its biosimilar infliximab, CT-P13, sold in Europe as Remsima.

While acknowledging the role that the Orphan Drug Act had in incentivizing drug companies to develop treatments for small populations suffering from rare diseases, America’s Health Insurance Plans (AHIP) says pharmaceutical companies are using orphan drug status to create blockbuster drugs that are then used to treat other common medical conditions.

A recent study says step therapy in rheumatoid (RA) or psoriatic arthritis (PsA) can hurt treatment outcomes.

While it is well understood that timely access to treatment is key for the management of rheumatic diseases, respondents to The American College of Rheumatology (ACR) 2019 Rheumatic Disease Patient Survey reported difficulty accessing and paying for their therapies in the past year.

It is already understood that a longer disease duration and delays in using disease-modifying antirheumatic drugs (DMARDs) in patients with rheumatoid arthritis (RA) is associated with worse disease control, but a new study, published just last month, has shown that the number of conventional DMARDs used before starting anti–tumor necrosis factor (anti-TNF) therapy could reduce the magnitude of a patient’s response to anti-TNFs like adalimumab.

A new report released Monday by UnitedHealth Group finds that administering specialty drugs—which are typically injected or infused—in homes or in independent physician offices instead of hospitals could save as much as $4 billion each year.

For patients with rheumatoid arthritis (RA), avoiding damage to cartilage and bone in the joints is a key consideration for treatment. While anti–tumor necrosis factor (anti-TNF) therapies are used to treat RA and reduce joint destruction, the available anti-TNF agents, both originator and biosimilar, have not been directly compared with one another or with placebo in terms of their impacts on joint damage. A new study, published last week, attempted to address that gap in the literature by conducting a meta-analysis of randomized controlled trials (RCTs).

Recently, researchers reported on 7-year interim results from the STRIVE registry and said that the results show that most children are able to tolerate adalimumab plus methotrexate well.

One recent paper analyzed data from 3 studies on down-titration of etanercept in patients with rheumatoid arthritis (RA) and concluded that patients who have achieved disease control according to a stringent definition have a greater likelihood of remaining in remission after reducing their dose or withdrawing etanercept.

Results of a phase 3 trial of IBI303, a proposed adalimumab biosimilar referencing Humira, showed that it is therapeutically equivalent in terms of efficacy, safety, and immunogenicity to the originator product, according to a study published in the first issue of The Lancet Rheumatology.

A new paper published this month may help to allay some concerns that US providers may have about using FDA-approved biosimilar rituximab.

Amgen announced yesterday that it will acquire apremilast (Otezla) from Celgene. The small-molecule drug, which inhibits phosphodiesterase 4, specific for cyclic adenosine monophosphate, is an orally administered therapy for patients with psoriatic arthritis and patients with plaque psoriasis who are candidates for phototherapy or systemic therapy.
