Drug developer Biocad received approval for its rituximab biosimilar, BCD-020 (Acellbia) in Russia in 2014, and since that time, the drug has been launched in Russia and in multiple other markets around the world. While Biocad has not specified whether it plans to pursue regulatory approval for the biosimilar in the European Union, the company has announced ambitions to enter the EU market with some of its products, and researchers have published new data for the biosimilar in both oncology and rheumatology indications.

In Crohn disease (CD), anti–tumor necrosis factor therapies like adalimumab have provided an alternative to long-term corticosteroid therapy and have reduced the need for many patients to have surgical interventions. It has been proposed that early treatment with biologics may lead to better outcomes and fewer complications—like strictures and fistulae—and findings from a recent study support that assertion.

Researchers have hypothesized that signaling through the vascular endothelial growth factor (VEGF) pathway could have immunomodulatory effects, and a recent study reports on a phase 2 trial that assessed a combination of the immune checkpoint inhibitor nivolumab with the anti-VEGF agent bevacizumab, which now has a commercially available biosimilar.

The fact that biologic drugs are typically infused or injected poses numerous challenges, including discomfort for patients, instability under some storage conditions, and the generation of needle waste. Researchers have long sought a way to deliver biologics orally, and some teams have even reported progress toward the goal of delivering monoclonal antibodies in coated tablet forms. Now, researchers have reported in Nature Medicine that a luminal unfolding microneedle injector could be a feasible delivery device for biologic drugs like insulin.

Coherus BioSciences and Amgen have reportedly settled a patent lawsuit over biosimilar adalimumab.

A recent study assessed tofacitinib versus anti–tumor necrosis factor (anti-TNF) agents using data from the Corrona registry, a large, prospective, observational database of patients with rheumatoid arthritis (RA) in more than 174 practices in 41 US states.

The issue of whether to switch patients currently taking biologics to biosimilars has been playing out in Canada over the past week, as mandated switching begins in British Columbia, while a reference product maker fights against a possible similar change in 2 other provinces.

Because stand-alone pharmacokinetic (PK) studies are usually designed to focus on intrinsic and extrinsic factors that have a high potential to affect drug exposure, they leave other possible interactions unstudied; population PK (popPK) analysis allows for an assessment of multiple factors that are not otherwise evaluated in healthy volunteers and allows for a larger number of individuals to be included.

President Trump’s choice to lead the FDA faced some questions, but not many, about drug pricing, according to various press reports about the Senate committee hearing Thursday regarding the nomination of Stephen Hahn, MD, FASTRO, the chief medical officer of MD Anderson Cancer Center.

On Monday, Polpharma Biologics announced that it has randomized the first patients in its phase 3 study of PB006, a proposed natalizumab biosimilar, and patients have begun to receive the study medication.

The field of biosimilar contenders for anti–vascular endothelial growth factor (anti-VEGF) therapies is taking shape, with biosimilar developer Coherus seeking to launch its ranibizumab biosimilar in 2021 and Samsung Bioepis having reached a commercialization agreement for 2 biosimilar anti-VEGFs of its own. Last week, a study published in JAMA Ophthalmology supported the use of anti-VEGF agents in wet age-related macular degeneration (AMD), saying that, though these drugs are costly, they may provide substantial economic value to both patients and society.

The World Health Organization (WHO) this week announced its pilot procedure for the prequalification of human insulin as means to facilitate access to safe, effective, and quality-assured insulin and insulin biosimilars for type 1 and type 2 diabetes in low- and middle-income countries.

Researchers report that there were no differences in visual acuity letter score (VALS) and central subfield thickness (CST) outcomes at month 24 between patients treated with bevacizumab and those treated with aflibercept in the SCORE2 study.

The high cost of healthcare is putting a strain on employers who provide health insurance coverage to their employees, and prescription drug prices are now front and center in the push to make coverage more affordable to provide to American workers.

Samsung Bioepis announced Wednesday that it has entered into a new commercialization agreement with partner Biogen for 2 ophthalmology biosimilars that are currently in development.

A recent study from Romania examined the efficacy and safety of biosimilar etanercept SB4 (Benepali) compared to originator etanercept in a real-life cohort of patients with rheumatoid arthritis (RA).

On Friday, President Donald Trump announced that he intends to nominate Stephen Hahn, MD, FASTRO, to be the next FDA commissioner.

In a research letter appearing this week in JAMA Internal Medicine, authors from Oregon Health and Science University raised the question of whether the “large and increasing revenue from eculizumab” could be tied to off-label use for non-approved indications.

In its third quarter 2019 financial results, AbbVie, maker of the blockbuster Humira, said that its international revenues for the brand-name adalimumab were $1.049 billion, or a decrease of 33.5% on a reported basis, after having faced competition from biosimilars.

A bipartisan bill introduced in the Senate this week aims to address the growing issue of drug shortages.

Drug maker Formycon announced today that it has begun a phase 1 clinical trial of its proposed ustekinumab biosimilar, FYB202, referencing Stelara. Ustekinumab is the first available therapy to target the interleukin-12 and -23 pathway.

As biosimilars for innovator biologics advance, drug makers are seeking new indications for products in their portfolios as a means to protect their sales against oncoming—or existing—competition. This month saw 3 notable label developments for drugs made by Janssen, Alexion, and AbbVie.

During the United European Gastroenterology Week 2019, held October 29-23 in Barcelona, Spain, researchers from Celltrion presented pooled data from 3 postmarketing studies of CT-P13 in patients with inflammatory bowel disease (IBD) that underscore the safety of the biosimilar.

The World Health Organization (WHO) and the International Generic and Biosimilar Medicines Association (IGBA), an umbrella organization with members including the Association for Accessible Medicines, Medicines for Europe, and a number of other national and regional generic and biosimilar organizations, have signed a memorandum of understanding.

Drug maker Pfenex announced this week that it has completed its comparative use human factors study for its follow-on teriparatide product, PF708, referencing the osteoporosis drug Forteo.

NeuClone said Thursday that it has begun dosing participants with its proposed ustekinumab biosimilar, referencing Stelara, in a phase 1 trial.

The Belgian Competition Authority, which contributes to implementing Belgium’s competition policy by addressing anticompetitive practices, announced that it is conducting inspections of some drug makers suspected of having implemented “restrictive practices aimed at limiting, delaying or even preventing the entry into the market or the expansion of biosimilar medicines competing with existing medicines."

The Japanese Adverse Drug Event Report (JADER) database, a large, published database managed by the Pharmaceuticals and Medical Devices Agency for pharmacovigilance, collects spontaneous reports as a means to detect adverse events (AEs) related to drugs, and a newly published study used the JADER data to assess AEs related to the reference infliximab and to the biosimilar, CT-P13.

While eculizumab is being targeted by multiple biosimilar developers who are in phase 3 clinical trials with their competitive products, spending on eculizumab is reaching concerning levels; as such, it is increasingly important to clarify eculizumab’s place in the treatment paradigm for myasthenia gravis (MG).

While biosimilar stakeholders’ eyes have been on the recent launch of new products and on policy proposals that stand to impact these therapies, several new proposed biosimilar agents are making their way into clinical trials.
