Treating ankylosing spondylitis (AS) is costly, even in high-income nations. In lower-income countries, patients may face serious challenges in accessing high-cost drugs, like anti–tumor necrosis factor agents, even when biosimilars are available.

The partnership says that it will launch the drug in the European Union on or after October 16, 2018.

During the 20th Asia Pacific League of Associations for Rheumatology (APLAR) Congress, held September 6 to 9 in Kaohsiung, Taiwan, researchers presented on real-world experience with switching to biosimilars in treating rheumatic diseases.

The State of California has filed suit against drug maker AbbVie, alleging that the company provided kickbacks to healthcare providers throughout the state to encourage them to prescribe its brand-name adalimumab, Humira, and used a network of registered nurses to mislead patients about the risks associated with the drug.

The bill, introduced in March 2018 by Senator Susan Collins, R-Maine—together with Senators Claire McCaskill, D-Missouri, and Debbie Stabenow, D-Michigan—eliminates so-called “gag clauses” that prevent pharmacies from telling consumers whether they could spend less on their medication by paying out-of-pocket.

Cetuximab (Erbitux), an anti-epidermal growth factor receptor (anti-EGFR) monoclonal antibody used in the treatment of head and neck and colorectal cancer, so far faces no biosimilar challengers. However, Chinese researchers are reporting positive preclinical results for a proposed biosimilar, APZ001.

The improved efficacy of a biologic drug in combination with a conventional treatment in rheumatoid arthritis (RA) has been well demonstrated, but some biologic-naive patients are unable to tolerate drugs such as methotrexate. Limited data are available about which biologic to select for monotherapy in such patients, however.

On September 13, the European Medicines Agency (EMA) published new, patient-focused materials that aim to make patients aware of biosimilar medicines and how the EMA assures that they are as safe and effective as reference biologics.

Rituximab-based immunochemotherapy can be safely applied in patients after obinutuzumab-associated anaphylaxis, but the existing risk of cross­reactivity should be considered, and careful monitoring of such patients during rituximab infusion is required.

This week, Boehringer Ingelheim announced results from a 16-week phase 3 study that confirmed biosimilar adalimumab-adbm (to be sold as Cyltezo) was clinically equivalent to the reference product, Humira.

Up to 60% of Crohn disease patients taking an anti—tumor necrosis factor (TNF) monoclonal antibody medication eventually stop responding to treatment, but the optimal management of these patients has not been clearly defined.

A new study suggests that CD8+ natural killer cells are a biomarker that can predict therapeutic outcome for patients with ankylosing spondylitis who are administered anti–tumor necrosis factor agents because they are nonresponsive to conventional treatment.

Adherence and persistence rates for biologic drugs are still low in the United States, leading to suboptimal patient outcomes and putting a substantial burden on the healthcare system.

Only 38% of Americans say that they are either very confident or somewhat confident that the administration’s plan will result in paying less for their prescription drugs.

Two pivotal studies of biosimilar epoetin alfa (Retacrit) versus its reference (Epogen) in patients undergoing hemodialysis have shown that the biosimilar and the originator have comparable safety and efficacy. In the phase 3b PIEDA (Phase 3b Investigation of Erythropoietin Drugs Using a Specified Dosing Algorithm) study, investigators sought to further investigate how switching from the reference to the biosimilar affects maintenance of hemoglobin levels when using an erythropoiesis-stimulating agent dosing algorithm.

Korean drug maker Celltrion says that the FDA’s Oncologic Drugs Advisory Committee (ODAC) will convene to discuss the Biologics License Application (BLA) for CT-P10, a proposed biosimilar rituximab, on October 10, 2018. CT-P10 is already authorized in the European Union, where it was approved under the trade names Rituzena, Ritemvia, Truxima, and Blitzima.

The National Institute for Health Research's Clinical Research Network maintains an active list of more than 800 clinicians—practicing in oncology, gastroenterology, endocrinology, and dermatology—who are interested in delivering trials of biosimilar medicines.

Xbrane’s lead biosimilar candidate is a ranibizumab product (referencing Lucentis), developed in collaboration with Stata, that is moving into a pivotal clinical trial. The study will enroll patients with wet age-related macular degeneration across 16 countries.

Since its inception, one of the best features of public and private Medicare Part B has been that patients are able to access their treatments without delay. That’s why healthcare providers, in collaboration with the patient, should be the primary treatment decision-makers. “Fail-first” policies prevent patients from receiving the right medication at the right time, and seniors can’t live with delays or risk disease destabilization.

“Biosimilars offer incredible health and economic opportunities in the United States, but unless substantial barriers are surmounted, these opportunities will not be fully realized,” say the report's authors.

While both the biosimilar filgrastim and biosimilar pegfilgrastim were effective in reducing the incidence of neutropenia, adverse events related to granulocyte-colony stimulating factor therapy were significantly higher in patients who received pegfilgrastim.

The European Union already has far more approved biosimilars—45 products referencing 15 medicines—than does the United States, but as a newly released report from IQVIA states, the number of European biosimilars available today represents just a fraction of what the market is expected to contain in the coming years, raising questions about the sustainability of the market.

Writing in the European Medical Journal, Anna La Noce, MD, PhD, and Marcin Ernst, MD, MBA, explain that much confusion about switching between biosimilars and reference products in the United States versus in the European Union arises from different uses of the term “interchangeability.”

Two research letters, published concurrently in the Journal of the American Medical Association, focused on biosimilars and their role in the Medicare population.

Currently, UK eligibility criteria for starting biologics in patients with rheumatoid arthritis (RA) set a threshold of a disease activity score in a count of 28 joints of 5.1 or higher—the threshold for severe disease—on at least 2 occasions measured 1 month apart.

Though biosimilars have the potential to provide a less costly option for patients, the products have not seen the uptake in the marketplace that the FDA had expected. This apprehension was reiterated in FDA Commissioner Scott Gottlieb’s comments at the meeting: “I’m not satisfied with the current state of the biologics market and biosimilars in particular.”

Janssen’s drug, sold in New Zealand as Eprex (and in the United States as Epogen) would lose funding after a transition period beginning in February 2019. After the close of the transition, only Novartis’ approved biosimilar, sold as Binocrit, would be eligible for funding in community and hospital settings.
