Using the biosimilar resulted in a significantly lower drug acquisition cost, at $533.40 in the biosimilar group versus $1261.90 in the reference group.

The Inflammatory Bowel Disease Net, an official working group of the Swiss Society of Gastroenterology, has issued a new position statement on the use of biosimilars in treating inflammatory bowel disease (IBD).

China-based Clover Biopharmaceuticals announced this week that it has dosed the first patient in a phase 3 clinical study of SCB-808, a proposed etanercept biosimilar referencing Enbrel.

While anti–tumor necrosis factor (anti-TNF) drugs are effective at treating a range of inflammatory diseases, some limited data suggest that they may, paradoxically, result in a higher risk of developing other de novo inflammatory conditions.

When it comes to US biosimilars, 2019 was the busiest year yet for regulatory activity, with a bevy of new approvals and the publication of long-awaited guidance documents.

Intravitreal injection with anti–vascular endothelial growth factor (anti-VEGF) drugs has represented a major step forward for patients with retinal diseases, and the upcoming biosimilars market for these drugs—including aflibercept and ranibizumab, as well as off-label bevacizumab—is beginning to take shape. However, there have been some lingering concerns about the safety of these drugs, as increased mortality has been reported after anti-VEGF treatment in the general population.

At the United European Gastroenterology Week 2019, held in Barcelona, Spain, earlier this year, a research team from the Netherlands reported on the prevalence of patients with inflammatory bowel disease (IBD) switching back to the reference infliximab after a previous switch to biosimilar CT-P13, and found that switching back appeared to be effective in patients with IBD.

Using the same dosing as treatment for lymphoma and older age were linked with higher odds of complete remission off therapy.

Given that anti–tumor necrosis factor (anti-TNF) agents are able to suppress mucosal inflammation, some have posited that these drugs could play a role in mitigating immune-related enterocolitis.

Among the features of the Part D structure is a federal reinsurance program in which, when a beneficiary reaches the catastrophic threshold in a given year, the government subsidizes 80% of remaining spending for the year. Part D plans pay 15%, and patients pay 5% in this scenario.

It has been hypothesized that metalloproteinases, and particularly MMP3, could a have a role in degrading anti–tumor necrosis factor drugs, leading to treatment failure in patients with inflammatory bowel disease (IBD).

The World Health Organization (WHO) this week prequalified its first biosimilar. The product, Samsung Bioepis’ biosimilar trastuzumab, Ontruzant, referencing Herceptin, could now become available to more patients with HER2-positive cancer in low- and middle-income countries.

Using a biosimilar can produce substantial cost savings in patients who are receiving infliximab therapy for inflammatory diseases like rheumatoid arthritis (RA), but dose escalations, which are frequent for those who use infliximab, can increase the cost of therapy, even with a biosimilar.

Previously, such chemically synthesized polypeptide products were excluded from the regulatory transition, so subsequent-entry products referencing these drugs would not be eligible for biosimilars or interchangeable product approval. Such products would also not be eligible for generic drug development.

Pfizer gained FDA approval for its biosimilar trastuzumab, Trazimera, in March 2019, and is slated to launch in the United States on February 15, 2020. Ahead of that milestone, researchers last week reported long-term safety and overall survival (OS) data for the Herceptin biosimilar in patients with HER2-positive metastatic breast cancer.

In May of 2018, drug maker Lupin announced that the European Medicines Agency would review its application for YLB113, a proposed etanercept biosimilar referencing Enbrel. This week, results of a phase 3 study of the biosimilar in patients with rheumatoid arthritis (RA) revealed the similarity of the product with its reference, and also demonstrated that the product has lower immunogenicity than the reference drug.

Outlook Therapeutics, formerly known as Oncobiologics, said this month that it has reached an agreement with the FDA on 3 special protocol assessments for clinical trials of ONS-5010, a formulation of bevacizumab intended to treat retinal diseases.

On Thursday, the Senate voted to confirm Stephen Hahn, MD, FASTRO, chief medical executive at the University of Texas MD Anderson Cancer Center, as the 24th commissioner of the FDA.

During this week’s annual meeting of American Society of Hematology, researchers from Canada reported that using biosimilar filgrastim could result in substantial savings.

An agreement on the United States–Mexico–Canada Agreement (USMCA), a trade deal that updates the North American Free Trade Agreement, has been reached, and proponents of biosimilars and generics have cause to celebrate after the removal of provisions that some said would hinder competition.

During this week’s 61st meeting of the American Society of Hematology (ASH), researchers reported on eculizumab, a prospective biosimilar, and the long-acting ravulizumab.

Celltrion and Teva’s biosimilar rituximab, CT-P10, Truxima, recently launched in the United States. The product is the first rituximab biosimilar to become available to US patients, and during this week’s 61st meeting of the American Society of Hematology (ASH), 2 research teams presented data that highlight the biosimilar’s safety and efficacy in patients with lymphoma.

The FDA has approved Amgen’s infliximab biosimilar, Avsola (infliximab-axxq), referencing Remicade.

NeuClone did not specify whether it intends to move to a phase 3 clinical trial for the biosimilar. In fact, in its statement on the phase 1 results, the company noted that phase 3 trials are not required to achieve regulatory clearance.

While there is no question that falling prices that come with competition are cause for optimism in the United States, which is burdened by rising drug costs, some experts from Europe caution that a focus on price alone misses key reasons to use biosimilars.

Researchers from biotech company Tetra Therapeutics have reported that, in their retrospective population-based study of 56 million patients with inflammatory diseases, use of anti–tumor necrosis factor (anti-TNF) agents was linked with a reduced risk of Alzheimer disease.

Amgen and pharmacy benefit manager (PBM) Abarca this week announced that they have entered into an outcomes-based contract for brand-name etanercept, Enbrel.

HR 3 proposes targeting for negotiation those drugs that consume a large share of the healthcare budget and that have limited biosimilar or generic competition. Writing in a perspective article in The New England Journal of Medicine, Peter B. Bach, MD, MAAP, a noted critic of high drug prices, proposed a different set of targets.

The European Commission has released a new report that highlights the role that biosimilars and generics will have in the wellbeing of European healthcare systems in the years ahead.

Mylan and Biocon have announced that their biosimilar trastuzumab, Ogivri, has become commercially available in the United States. The biosimilar, referencing Herceptin, is now available in a 420-mg multidose vial and a 150-mg single-dose vial.
