Biosimilar developer Samsung Bioepis has gained an updated label for its biosimilar adalimumab, Imraldi, referencing Humira. The biosimilar is now approved for storage in nonrefrigerated conditions for up to 28 days. This update means that the biosimilar can now be stored for an additional 2 weeks at room temperature.

A recently published study used data from the RA-BEAM trial to assess what proportion of treated patients achieve pain relief and in what time frame, and found that an oral small-molecule Janus kinase (JAK) inhibitor may have some advantages over adalimumab (Humira) when it comes to reducing rheumatoid arthritis (RA) pain.

Anti–vascular endothelial growth factor therapy is the standard of care for the first-line treatment of macular edema associated with central retinal vein occlusion or hemiretinal vein occlusion, and a number of therapeutic options are available, including aflibercept, ranibizumab, and off-label bevacizumab.

The subcutaneously administered trastuzumab contains the same monoclonal antibody as the intravenous formulation at a dose of 600 mg per 5-mL vial, plus a recombinant human hyaluronidase, to be used every 3 weeks. The hyaluronidase is used to increase the permeability of the extracellular matrix, allowing for administration of higher volumes and enhanced absorption of the drug.

The multicenter, randomized, noninferiority, double-blind, controlled trial was conducted in China among 554 patients with active ankylosing spondylitis.

The investigators found that the biosimilar and the reference in combination with a subdomain II–targeting antibody had similar in vitro inhibition rates for HER2 and HER3 heterodimerization.

A study published in The New England Journal of Medicine examining rituximab in membranous nephropathy found that it is noninferior to cyclosporine in inducing proteinuria remission at 12 months and is superior to maintaining long-term remission up to 24 months in patients at high risk for progressive disease.

The European Commission approved ravulizumab (Ultomiris) for adults with paroxysmal nocturnal hemoglobinuria.

Under the approach used by Kaiser Permanente, say the authors, in which oncologists have salaried incomes and are not reimbursed on a relationship to drug price, far higher generic uptake has been observed.

The Center for Biosimilars® recaps the 5 most-read stories of 2019 to date.

Two economists from the American Enterprise Institute (AEI) shot back at the idea that biosimilars are natural monopolies and should have their prices regulated by the government, as was proposed a little more than 2 months ago by critics who say that trying to wring lower drug prices through competition born from biosimilars is an experiment doomed to fail.

As more centers begin to switch patients from reference infliximab to biosimilar options, patients who have benefitted from rapid infusions of the reference product may want to continue to receive time-saving infusions that reduce the burden of lengthy visits to infusion centers.

Given the head-to-head data from the SPIRIT trial, Humira maker AbbVie may face even further challenges in trying to maintain its sales as newer products like ixekizumab advance in such therapeutic areas as psoriatic arthritis (PsA).

Amgen says it is withdrawing its European application for ABP 710, its biosimilar infliximab (referencing Remicade).

In a study conducted from 2017 to 2018 among all of the infliximab-treated patients with inflammatory bowel disease (IBD) in a single center, patients who were in clinical remission were invited to complete a questionnaire to assess their biosimilar knowledge and acceptance of a switch.

Mundipharma, a network of independent companies that operates in 120 countries worldwide and distributes a number of biosimilars in the European Union, has inked a deal with Budapest-based Egis Pharmaceuticals to distribute its biosimilar pegfilgrastim, Pelmeg, in 4 Eastern European markets: Hungary, Romania, Lithuania, and Latvia.

Starting in 2017, the Henry Ford Cancer Institute started using follow-on filgrastim (tbo-filgrastim, a product approved prior to the establishment of the biosimilar approval pathway in the United States) and biosimilar filgrastim (Zarxio) in stem cell mobilization prior to transplant.

The European Specialist Nurses Organisation has launched 7 new translations of its guide to the management of switches between reference biologics and biosimilars.

June 2019 was a busy month for oncology biosimilars, in both the supportive care and anticancer contexts, with regulatory activity and the presentation of reassuring new data.

The FDA has approved Pfizer’s bevacizumab biosimilar, bevacizumab-bvzr, referencing Avastin.

The Center for Biosimilars® recaps the top stories for the week of June 24, 2019.

Alexion Pharmaceuticals’ brand-name eculizumab (Soliris) gained its fourth approval, this time for the treatment of neuromyelitis optica spectrum disorder (NMOSD).

The FDA today announced a proposed rule that would amend regulations concerning the use of master files for biologics. According to the FDA, this rule is necessary to avoid any disruption to products that will transition from regulation as drugs to regulation as biologics in 2020.

Eli Lilly and Company, together with partner Innovent Biologics, announced today that China’s National Medical Products Administration will review its application for IBI301, a proposed rituximab biosimilar referencing MabThera and Rituxan.

The Biosimilars Council, a part of the Association for Accessible Medicines, has issued a new white paper in which it condemns abuses of the patent system that delay biosimilar competition. It also argues that legislative proposals to regulate settlements would “merely benefit companies investing in the creation of patent thickets.”

The US biosimilars market is really taking off, with 4 biosimilar products launched in the past year and 7 biosimilar products (Zarxio, Inflectra, Renflexis, Fulphila, Nivestym, Retacrit, and Udenyca) in total on the market, competing with 4 originator medicines. The projected annual savings to the US healthcare system could climb to $60 billion in 2023 for a 5-year total of $153 billion. Those projections come from the IQVIA Institute for Human Data Science, which also projects a near doubling of biosimilar product competition in the US biologics marketplace by 2023.

Data from switching studies will bolster another important facet of the biosimilars marketplace: patient and prescriber confidence. In a marketplace in which patients move from one formulary to another, from one year to the next in their journey with chronic illnesses, it will be helpful to know that interchangeable biosimilars offer equal safety and efficacy after multiple switches.

Amgen, Eli Lilly, and Merck, together with the Association of National Advertisers, have filed a lawsuit against HHS and CMS over the Trump administration’s rule requiring disclosure of list prices for drugs in direct-to-consumer television advertisements.

In this case, Pfizer hoped to launch its biosimilar bevacizumab in the UK market after the basic patent on the reference product, Genentech and Roche’s Avastin, expires in June 2020. However, the biosimilar maker has been hindered by what it has termed a patent thicket related to secondary patents.

Drug maker AbbVie today announced that it has reached a $63 billion transaction agreement under which it will acquire Allergan.
