While the United States continues to await the launch of the first FDA-approved biosimilar etanercept (Erelzi), in other parts of the world biosimilars of the reference etanercept (Enbrel) are being widely used in clinical practice, and recent research reports on the role that biosimilar etanercept plays in the treatment of ankylosing spondylitis (AS).

Recent research attempted to assess consumer response to the disclosure of drugs' list prices in direct-to-consumer advertising.

Acute severe ulcerative colitis (ASUC) can occur in up to 25% of patients with UC. Salvage therapy with infliximab or cyclosporine is standard first-line therapy for patients who do not respond adequately to intravenous corticosteroids, but questions have arisen about the cost-effectiveness of this approach versus early colectomy. A recent study, conducted in a tertiary hospital network in Australia, sought to compare healthcare utilization and costs between patients with ASUC who had early colectomy and those who were treated with infliximab.

In a long-running patent dispute with biosimilar developer Boehringer Ingelheim, AbbVie, maker of the brand-name adalimumab, Humira, has been ordered to produce documents related to its efforts to obtain patents that could shield its blockbuster drug from biosimilar competition.

This year, the biosimilar landscape will likely focus on interchangeability as biosimilars manufacturers and other stakeholders seek to reduce costs and increase uptake. This follows the 2018 trend of biosimilar litigation settlements and the attention in 2017 to the information exchanges, also known as the “patent dance,” laid out in the Biologics Price Competition and Innovation Act of 2009.

Drug maker Gedeon Richter’s RGB-02 is undergoing development as a proposed biosimilar to the reference pegfilgrastim, Neulasta, and researchers recently reported on the results of a phase 3 clinical study of the drug versus its reference in patients with breast cancer who were receiving chemotherapy.

Biosimilar developer Samsung Bioepis, a partnership between Samsung BioLogics and Biogen, has announced a new licensing agreement with the private equity firm C-Bridge Capital that will allow the drug maker to expand its reach into mainland China.

A recent study examining Medicare Part D reimbursement policies for off-label uses, using dermatology as a focus, found that health coverage decisions have significant shortcomings that could hamper patient access to evidence-based treatments.

The FDA recently released final guidance on the use of therapeutic proteins in developing biologics and biosimilars. "Immunogenicity Testing of Therapeutic Protein Products—Developing and Validating Assays for Anti-Drug Antibody Detection" represents current FDA thinking about developing and validating assays for anti-drug antibody (ADA) detection.

This week, the United States Court of Appeals for the Federal Circuit found that Momenta lacked standing to appeal a decision upholding a patent covering abatacept (Orencia) and said that Momenta’s appeal was rendered moot by the drug makers’ choice to stop developing its biosimilar.

GP2013, a biosimilar rituximab developed by Sandoz and licensed in the European Union under the brand names Rixathon and Riximyo, is used to treat both malignant and inflammatory diseases. A recently published paper, appearing in Arthritis Care and Research, says that researchers detected no safety risks when switching patients with rheumatoid arthritis from reference rituximab (Rituxan) to the biosimilar.

The Center for Biosimilars® recaps the top news for the week of February 4, 2019.

Express Scripts said this week that it expects US drug spending to rise about 2% over the next 3 years, lower than projected inflation rates. However, a lack of competition will affect 2 of the costliest categories of pharmaceuticals—inflammatory conditions and diabetes—between 2019 and 2021.

This week, Senator Patrick Leahy, D-Vermont, reintroduced The Creating and Restoring Equal Access To Equivalent Samples (CREATES) Act.

New research, published in BioDrugs, underscores the long-term efficacy and safety of treating rheumatoid arthritis (RA) with biosimilar rituximab, CT-P10.

Some stakeholders have welcomed the proposed rule to bar drug makers from giving pharmacy benefit managers rebates, while others raised serious concerns.

One emerging method to monitor potential differences is to apply aptamers: single-stranded DNA or RNA oligonucleotides. Aptamers can bind to various targets, and because they have a defined fold that can recognize a target with high affinity, they can be used as surrogate antibodies.

Mundipharma announced today that it has launched Pelmeg, a biosimilar pegfilgrastim referencing Neulasta, in Germany, the Netherlands, and Ireland.

Results from the phase 3 REFLECTIONS B327-02 study in patients with HER2-positive metastatic breast cancer (MBC) were first presented in abstract form, but have now been reported in detail.

In a newly published correspondence, Italian rheumatology providers called into question whether recently published results from the DANBIO registry can be used to guide non-medical switching from reference etanercept (Enbrel) to biosimilar SB4 (Benpali) in patients with inflammatory diseases.

The assumption that Medicare Part B payment rates lead providers to create higher drug utilization for costlier treatments in order to benefit from larger add-on payments is not correct, a recent white paper said. The paper from Xcenda, a part of AmerisourceBergen, also found similar results when looking at physician-administered drugs in the hospital outpatient setting.

On Friday, Fresenius Kabi announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion for its MSB11022, a biosimilar adalimumab referencing Humira. The CHMP issued its opinions for the marketing of 2 brand names of the drug: Idacio and Kromeya.

A recent white paper recaps the many barriers to biosimilar adoption in the United States and proposes a few ways that plans could change their reimbursement policies to help boost uptake.

A raft of biosimilars possibly coming to market is not expected to relieve the burden of healthcare costs in 2019, but it is possible that the combination of products in the queue, as well as reimbursement changes, could be the beginning of change, according to a drug pricing forecast out this week from Vizient.

Finnish-based biosimilar developer, Paras Biopharmaceuticals Finland Oy, said this week that it is ready to begin testing its potential romiplostim biosimilar in clinical trials.

While the body of reassuring data on the safety and efficacy of biosimilars continues to grow, worrisome information about stakeholders’ levels of awareness of these products is also coming to light, and January 2019 saw the publication of a spate of studies showing low levels of patient and provider education on biosimilars.
