Along with innovations in design comes the question of patients’ willingness to pay for features that differentiate self-injection devices from one another.

This week, researchers reported updated results from a post hoc subgroup analysis from the adjuvant period of treatment in the biosimilar’s phase 3 trial; these results, say the authors, demonstrate that the biosimilar, used in the adjuvant setting, has comparable efficacy and safety to the reference at 1 year.

Hungary-based Gedeon Richter announced today that it has launched a biosimilar teriparatide, Terrosa, in Europe. The drug, referencing Eli Lilly’s Forsteo (sold as Forteo in the United States), is used to treat osteoporosis. The product will also be sold under the brand name Movimya by the company's partner, Stada.

While drug makers who sell insulin in the United States have had the past decade to prepare for the transition, stakeholders within the diabetes community must grapple with the potential impacts that this regulatory change could have.

In a one-page order filed last week, a panel of judges for the US Court of Appeals for the Federal Circuit denied Genentech’s motion for an injunction that would have blocked Amgen from selling its biosimilar bevacizumab, Mvasi, pending the outcome of an appeal.

Upadacitinib is expected to help AbbVie continue to lead in the immunology market after biosimilar competition emerges for adalimumab in 2023. The approval for the treatment of RA is one of 6 indications that AbbVie’s chief executive officer, Richard Gonzalez, said in a 2018 presentation that the company expects to have approved and launched by 2022.

Samsung Bioepis has begun recruiting patients with paroxysmal nocturnal hemoglobinuria (PNH) in India for a phase 3 clinical study of its proposed eculizumab biosimilar, SB12, referencing Soliris.

LG Chem’s biosimilar etanercept, LBEC0101, referencing Enbrel, recently gained approval in Japan and the Republic of Korea. Among the data that led to its authorization were those deriving from a phase 3 study that demonstrated the biosimilar had equivalent efficacy and a comparable safety profile to the reference product. Recently, researchers reported on a single-arm, open-label extension study in patients with rheumatoid arthritis (RA) who completed the 52-week phase 3 study.

In its August 2019 network bulletin, UnitedHealthcare indicated that, beginning October 1, 2019, biosimilar bevacizumab (Mvasi) and biosimilar trastuzumab (Kanjinti), both made by Amgen, will be preferred products for commercial and community plans.

This week, a pair of papers detailing the clinical program for the biosimilar appeared in Pharmacology Research and Perspectives.

This month, researchers published data from a phase 3 study of the biosimilar in patients with moderate to severe rheumatoid arthritis (RA) after previous phase 3 data were reported for a study in patients with severe plaque psoriasis.

Instead of the “totality of the evidence” approach to biosimilars, authors of a new paper propose a “confirmation of sufficient likeness” paradigm.

The Canadian government has announced amendments to its regulations concerning patented drugs that it says will make medicines more affordable. According to Health Canada, these changes will save Canadians $13.2 billion (US $9.97 billion) over the next decade.

A judge for the United States District Court for the District of New Jersey has ruled in favor of Amgen in a long-running patent litigation concerning Sandoz’s biosimilar etanercept, Erelzi.

Among the patients who viewed positively framed video explanations of biosimilars, 67% were willing to switch.

A panel of judges for the United States Court of Appeals for the Federal Circuit has denied Genentech’s motion to block sales of Amgen’s biosimilar trastuzumab pending the outcome of an ongoing appeal.

OneOncology, a national partnership of community oncology practices, says that its partner practices have begun treating patients with 2 anticancer biosimilars: Kanjinti, a trastuzumab biosimilar referencing Herceptin, and Mvasi, a bevacizumab biosimilar referencing Avastin.

A study published this month proposes that biosimilars be assessed in a quantitative benefit-risk analysis to assess whether what the authors call “uncertainty in the clinical performance of biosimilars” can be countered by lower pricing.

Not everyone shares the view that authorized generics are a boon, and concerns are rising that the marketplace may soon see the advent of authorized biologics.

Samsung Bioepis’ etanercept biosimilar, SB4, has been available in multiple markets since it was authorized by the European Commission in 2016, and this week, a new systematic review reported on real-world evidence on the use of the biosimilar in treating inflammatory diseases.

Biosimilar earnings were due in large part to the European launches of biosimilar trastuzumab (Kanjinti) and biosimilar adalimumab (Amgevita), which Amgen said are progressing in line with expectations and annualizing at more than $300 million.

According to Momenta, the decision is a result of “changes in the market opportunity associated with Humira patent litigation settlements.”

Data continue to accrue on the use of biosimilar infliximab, CT-P13 (Inflectra, Remsima), in a variety of disease states, and a recent study among patients with ankylosing spondylitis (AS) who were treated with the biosimilar demonstrated infrequent discontinuation of therapy.

A study published this week in PLoS Medicine suggests that brand-to-brand competition is not likely to reduce drugs’ list prices.

Celltrion announced that it has begun recruiting patients with inflammatory bowel disease in Ohio for a phase 3 clinical trial of its subcutaneous formulation of biosimilar infliximab, CT-P13 (Inflectra, Remsima). The study is intended to support an application for the formulation to the FDA.

July 2019 was a busy month for biosimilars on the regulatory front; not only did the FDA approve new products, but numerous policy proposals with a potential impact on biosimilar regulation were put forward by law makers.

The study sought to assess the efficacy, tolerability, and safety of CT-P13 versus its reference and versus adalimumab in patients with Crohn disease (CD).

In yesterday’s decision, the panel agreed with the district court that, during prosecution of the patent, Amgen “clearly and unmistakably surrendered salt combinations other than the particular combinations recited in the claims,” and that prosecution history estoppel bars Amgen from succeeding on its infringement claims under the doctrine of equivalents.

According to Mylan, the deal will allow the new company to “meaningfully expand the geographic reach” of its portfolio and its future products, including its complex generics and its biosimilars, into markets where Upjohn has existing infrastructure.

Senator Dick Durbin, D-Illinois, said that the “termination cliff” on the transition date creates a “perverse incentive that could delay approval” for biosimilar insulins, and said that the new legislation would create a faster approval path for lower-cost products.
