Teva announced this week that the FDA has approved its tbo-filgrastim (Granix), a follow-on product referencing Neupogen, to reduce the duration of severe neutropenia in patients as young as 1 month old who have nonmyeloid malignancies and are receiving myelosuppressive chemotherapy.

Korean drug maker Celltrion has announced that it ready to begin phase 1 and phase 3 clinical trials for CT-P17, a proposed adalimumab biosimilar referencing AbbVie’s Humira, which is used to treat a variety inflammatory diseases. The trials will be conducted simultaneously at 75 sites in 8 nations in the European region including the United Kingdom, and the company indicates that the trials will be completed by 2020.

Australia’s Therapeutic Goods Administration has approved Celltrion’s Herzuma—the country’s first biosimilar trastuzumab—referencing Herceptin.

The updated treatment approach will allow clinicians, based on individual patients’ outcomes, to lengthen the intervals between injections for patients with neovascular age-related macular degeneration (AMD) who are already in the first year of treatment. That could mean fewer injections and fewer trips to the clinic for patients with AMD.

This week, the district court of Massachusetts granted Celltrion’s motion for a summary judgment of non-infringement of the last patent in question in the long-running Janssen v Celltrion case.

The World Health Organization (WHO) has produced a draft Question and Answer (Q&A) document that gives additional clarification to its 2009 guidelines for evaluating similar biotherapeutic products, particularly with respect to evaluating biosimilars of monoclonal antibodies.

Drug maker Mylan, which in June received FDA approval for its biosimilar pegfilgrastim, Fulphila, confirmed in an email to The Center for Biosimilars® that it has launched the biosimilar in the United States marketplace. Fulphila is the fourth biosimilar—and the first pegfilgrastim biosimilar—to become available to US patients.

A little over a year after having received FDA authorization to commence its clinical program, Glenmark Pharmaceuticals has announced that its phase 1 study of GBR 310 revealed similar pharmacokinetic, pharmacodynamic, safety, and immunogenicity profiles between its proposed omalizumab biosimilar and the reference product, Xolair.

According to the report, Medicare Part D drugs that demonstrated the lowest annual cost increases offered higher average rebates than drugs with the highest annual cost increases.

On July 20, the United States Court of Appeals for the Federal Circuit ruled in the case of the St Regis Mohawk Tribe v Mylan Pharmaceuticals that sovereign immunity does not extend to inter partes review (IPR) proceedings.

Catch up on the week’s top policy, clinical, business, regulatory, legal, and international news from the world of biosimilars.

The FDA has finalized its guidance on labeling of biosimilar products, and FDA Commissioner Scott Gottlieb, MD, called the finalized guidance "one of a suite of deliverables" that will be unveiled as part of the Biosimilars Action Plan.

Catch up on the week’s top rheumatology, gastroenterology, clinical practice, regulatory, policy, and business news from the world of biosimilars.

Intravenous administration of the anti–vascular endothelial growth factor treatment bevacizumab at high doses can result in serious, systemic adverse events (AEs). Additionally, tumors can become resistant to therapy and adopt a more invasive growth pattern. Thus, delivering bevacizumab for the treatment of cancer at a lower dose in a manner that avoids systemic AEs is necessary.

Eales disease (ED) is a common, idiopathic, inflammatory retinal vasculitis that particularly affects young adults. Current treatments available for ED include corticosteroids, laser photocoagulation, retinal cryotherapy, and surgery, but a recent study found that using intravitreal bevacizumab injections may produce better outcomes and reduce the need for surgery.

Primary sclerosing cholangitis (PSC) is a chronic, immune-mediated, progressive biliary disease that is closely associated with inflammatory bowel disease (IBD). PSC has no cure, and up to 40% of cases eventually require patients to receive liver transplants. Given the efficacy of biologics in treating IBD, the potential to treat PSC with these same drugs is a matter of interest for healthcare providers.

This month saw a variety of developments in the world of biosimilar drugs for the treatment of rheumatic diseases.

Intestinal Behçet disease (BD), which is an immune-mediated, chronic, inflammatory intestinal disease, can be difficult to treat, in part because the pathogenesis of intestinal BD is unclear. However, as data for using anti–tumor necrosis factor (anti-TNF) drugs have been accumulating in the treatment of inflammatory bowel disease (IBD), which has a similar clinical presentation, the potential to treat BD with these agents is under investigation.

Guidelines recommend that disease activity should be assessed every 1 to 3 months in patients with high or moderate disease activity, and every 6 to 12 months in those with low disease activity or remission, but implementation of these principles has not been well evaluated in the United States.

Anti–tumor necrosis factor (TNF) agents, widely used in rheumatology and gastroenterology, carry some safety risks. While the risk of infection or malignancy are common concerns, neurological complications, while rare, are also possible.

During the fourth congress of the European Academy of Neurology, held in Lisbon, Portugal, from June 16 to 19, researchers reported on CinnaGen’s biosimilar interferon beta 1A drug, CinnoVex, in treating multiple sclerosis (MS).

If European League Against Rheumatism guidelines are followed, when a patient with rheumatoid arthritis (RA) does not reach remission or a state of low disease activity after 6 months of treatment, then the patient’s treatment should be modified regardless of the drug therapy being used (biologic or small molecule).

The American Society of Clinical Oncology’s (ASCO) annual meeting, held June 1-5, 2018, in Chicago, Illinois, featured results of numerous studies on biosimilars in anticancer and supportive care. Here are 5 key takeaways from the meeting.

Republic of Korea-based biosimilar developer Celltrion, maker of Inflectra, has announced that it will launch a contract development and manufacturing business to develop novel agents alongside its biosimilar pipeline.

Biosimilar developer Celltrion has resubmitted its Biologics License Application (BLA) for a proposed rituximab biosimilar, CT-P10, to the FDA for regulatory consideration. The company received a Complete Response Letter for the drug in April 2018, after having received an earlier warning letter from the agency that raised concerns about the company’s manufacturing processes.

While it is already known that obesity may contribute to an increased risk developing some immune-mediated inflammatory diseases, as well as more severe disease activity and a higher burden of hospitalization, a new review found that obesity is also a predictor of inferior response to anti–tumor necrosis factor (anti-TNF) agents.

The authors of a recent study report that the addition of a disease-modifying anti-rheumatic drug (DMARD) or a switch to ustekinumab showed greater efficacy than changing anti–tumor necrosis factor (anti-TNF) treatments in patients with inflammatory bowel disease (IBD) who develop paradoxical arthritis.

At the International Society for Pharmacoeconomics and Outcomes Research’s (ISPOR) 23rd Annual International Meeting in Baltimore, Maryland, researchers and speakers highlighted emerging trends in biosimilars. Here are 7 key takeaways from the conference.

In treating ankylosing spondylitis, anti–tumor necrosis factor (anti-TNF) drugs produce a response in approximately 60% of patients. For the 40% of patients who do not respond to treatment, previous studies have suggested that patient characteristics, including sex, may play a role.

Today, Australian drug developer NeuClone announced positive preclinical results of its proposed ustekinumab biosimilar referencing Stelara. Ustekinumab is a monoclonal antibody that targets interleukin-12 and -23, and the reference product is approved to treat plaque psoriasis, psoriatic arthritis, and Crohn disease.
