The FDA requested that Retacrit's maker provide data on subcutaneous administration, given that immunogenicity of a protein can be impacted by route of administration. Results from that study, newly published in Kidney International Reports, show that the subcutaneous administration of the biosimilar has similar safety and efficacy to subcutaneous administration of the reference (Epogen, Procrit).

Vial sharing for bevacizumab that would otherwise have been discarded yielded a 97.88% reduction in the total cost of a single year of intravitreal injections, as well as a 96.54% increase in the number of injections performed.

The drug maker indicates that, conservatively, it plans to see 60% to 70% erosion for rituximab (Rituxan, MabThera), trastuzumab (Herceptin), and bevacizumab (Avastin) by 2023, leaving a gap of approximately $9.6 billion for the company to fill.

Sandoz’s biosimilar filgrastim was first approved in Europe in 2009 under the name Zarzio (later, the same drug was approved as Zarxio in the United States). Since that time, the number of biosimilars approved for use in the oncology field has grown substantially, and a recent review says that the past decade of experience with biosimilar filgrastim underscores the strong scientific basis for the extrapolation of indications for biosimilars.

The Biosimilars Council, a part of the Association for Accessible Medicines, has issued a second component of its recent white paper on barriers to biosimilars in the United States; the newly published segment highlights postmarket barriers to biosimilar adoption and says that they have taken a significant toll on the US healthcare system in terms of lost savings.

The United States Court of Appeals for the Third Circuit has sided with Johnson & Johnson (J&J) and its Janssen division, requiring a dispute between the Remicade maker and Rochester Drug Cooperative to be sent to arbitration.

While it is well understood that timely access to treatment is key for the management of rheumatic diseases, respondents to The American College of Rheumatology (ACR) 2019 Rheumatic Disease Patient Survey reported difficulty accessing and paying for their therapies in the past year.

Samsung Bioepis has launched its biosimilar etanercept, SB4, in Brazil. The biosimilar, which is being sold as Brenzys, was approved in Brazil in 2017 to treat rheumatoid arthritis, ankylosing spondylitis, plaque psoriasis, psoriatic arthritis, and nonradiographic axial spondyloarthritis.

During this week’s meeting of the European Committee for Treatment and Research in Multiple Sclerosis, held September 11-13 in Stockholm, Sweden, researchers are presenting new data for eculizumab in the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare autoimmune disorder that typically affects the optic nerves and spinal cord and that can cause significant, irreversible disability.

Just last week, Sandoz indicated that it will commercialize a biosimilar of the multiple sclerosis (MS) drug natalizumab (Tysabri). This week, during the 35th meeting of the European Committee for Treatment and Research in Multiple Sclerosis, held September 11-13 in Stockholm, Sweden, researchers will present data that help contextualize natalizumab’s place in the treatment paradigm for MS.

A paper published in Pharmaceutics describes development and validation of a production process for 5 mg tablets of infliximab, using biosimilar CT-P13 (Remsima, Inflectra), for the treatment of inflammatory bowel disease.

Last week, Alexion disclosed in a filing to the US Securities and Exchange Commission that the European Patent Office did not grant Alexion its request for 2 patents on its brand-name eculizumab product, Soliris, a C5 complement inhibitor that treats rare and ultrarare diseases.

For patients with rheumatoid arthritis (RA), avoiding damage to cartilage and bone in the joints is a key consideration for treatment. While anti–tumor necrosis factor (anti-TNF) therapies are used to treat RA and reduce joint destruction, the available anti-TNF agents, both originator and biosimilar, have not been directly compared with one another or with placebo in terms of their impacts on joint damage. A new study, published last week, attempted to address that gap in the literature by conducting a meta-analysis of randomized controlled trials (RCTs).

Genentech has reached a memorandum of understanding with JHL Biotech in its civil lawsuit related to the theft of Genentech’s trade secrets.

China-based drug maker TOT Biopharm is developing TAB008 as a biosimilar of the reference bevacizumab, Avastin. TOT has recently indicated that it is in the midst of a phase 3 clinical trial of the biosimilar, and last month, results of a phase 1 study of the biosimilar were published in Frontiers in Pharmacology.

Amitabh Chandra, PhD, Ethel Zimmerman Wiener professor of public policy and director of health policy research at the Harvard Kennedy School of Government, says that while price regulation is not impossible, “It’s very, very hard to do. Given that it’s hard to do, do we need to do it?”

England’s National Health Service (NHS) says that it has saved £110 million (US $134 million) by implementing its policy to use the best-value adalimumab after the brand-name Humira lost European patent protection in October 2018.

Last week, the Patent Trial and Appeal Board (PTAB) instituted 3 inter partes review proceedings concerning patents on Alexion’s brand-name eculizumab, Soliris, a complement inhibitor that treats rare diseases. Amgen is the petitioner in all 3 cases, which were filed in February of this year.

Over the weekend, drug maker Biocon disclosed that it and partner Mylan have been issued a second Complete Response Letter (CRL) for their follow-on insulin glargine product referencing Lantus.

Sandoz, a Novartis division, announced today that it has entered into a global commercialization agreement with Poland-based Polpharma Biologics for a proposed natalizumab biosimilar referencing Biogen’s Tysabri. Natalizumab is a disease-modifying therapy used to treat relapsing-remitting multiple sclerosis (MS) as well as Crohn disease.

In the oncology realm, August 2019’s biggest business development was the forward momentum of Amgen’s 2 newly debuted oncology biosimilars, and perhaps the biggest news in the biosimilar space from the inflammatory disease perspective also involved Amgen and its involvement in a long-running patent dispute.

Amgen, maker of the brand-name pegfilgrastim (Neulasta), and Mylan, which partnered with Biocon to develop a biosimilar (Fulphila), have entered a joint status report in the District Court for the Western District of Pennsylvania.

A new paper published this month may help to allay some concerns that US providers may have about using FDA-approved biosimilar rituximab.

In a filing with the US Securities and Exchange Commission this month, Silicon Valley-based biotech company Revance Therapeutics said that it has entered into an amendment to a Collaboration and License Agreement with Mylan; the amendment extends the period of time Mylan has to decide whether to continue to develop and commercialize a biosimilar of Allergan’s onabotulinumtoxinA (Botox).

A Japanese postmarketing surveillance study of biosimilar infliximab CT-P13 (Inflectra, Remsima) concludes that the biosimilar and its reference, Remicade, are comparable in terms of efficacy and adverse drug reactions in patients with inflammatory bowel disease (IBD) and that the biosimilar is a cost-efficient option that is interchangeable with the reference in real-world practice.

Administering the brand-name pegfilgrastim (Neulasta) via an on-body injection device (sold as Onpro) carries some risk of device failure, resulting in a missed or partial dose of pegfilgrastim. A recent cost simulation found that, when taking this failure into account, assured prophylaxis with biosimilar filgrastim offers the greatest cost efficiency.

A more compelling rationale for switching medications—particularly in light of “marginal” cost savings provided by biosimilars in the United States—is necessary, says the guideline.

A new report from Matrix Global Advisors and the National Business Group on Health, sponsored by Boehringer Ingelheim, shows that employers could see substantial savings from biosimilars, but those savings won’t come without a concerted effort to encourage biosimilar use.

The study in patients with non-Hodgkin lymphoma (NHL) is the second of a pair of studies intended to facilitate regulatory submissions for the proposed biosimilar.

When Samsung Bioepis’ trastuzumab biosimilar, SB3 (Ontruzant), gained regulatory approval in multiple highly regulated markets, it did so on the strength of a data package including evidence from a phase 3 study in patients with HER2-positive early breast cancer. Later, it became apparent that some of the patients who received the reference product in the phase 3 study had been exposed to lots of Herceptin with a marked shift in relative antibody-dependent cell-mediated cytotoxicity (ADCC) activity.
