Regulatory

Dong-A ST, a biosimilar developer based in the Republic of Korea, has, together with Sanwa Kagaku Kenkyusho, filed for Japanese regulatory approval of DA-3880, a darbepoetin alfa biosimilar referencing Aranesp.

From the FDA’s hearing on the Biosimilar Action Plan to European approval of the first pegfilgrastim biosimilars, September was a banner month in biosimilar regulation.

The Initiative for Medicines, Access, and Knowledge (I-MAK) report notes that 89% of these applications were filed in the United States after Humira was already on the market, and 49% were filed after the first patent expired in 2014.

According to an unofficial estimate by the Congressional Budget Office, the Biosimilars Competition Act of 2018 will save about $100 million from 2019 to 2028.

Recent weeks have seen heightened debate over the need for phase 3 confirmatory trials for biosimilars, with some stakeholders calling these trials unnecessary and others going so far as to call them unethical. During the SMi 9th annual conference on Biosimilars and Biobetters, held September 26-27 in London, United Kingdom, Uwe Gudat, MD, who serves as head of clinical safety and pharmacovigilance at Fresenius Kabi, weighed in. “The subject I raise is rather provocative,” he acknowledged.

Samsung Bioepis announced that the FDA has accepted a Biologics License application (BLA) for its adalimumab biosimilar, SB5, referencing Humira.

While every biologics manufacturer has its own standards against which it measures a product’s consistency over time, there is an increasing need for harmonization of these in-house standards with a public standard that can serve as a benchmark for the reference product and all biosimilars. This, explained Meenu Wadhwa, PhD, is where World Health Organization (WHO) international standards come in.

Advocates took to Capitol Hill last week to brief lawmakers and their staff about the implications the recent CMS policy change may have on patient access to treatments.

The European Union (EU) today authorized its second pegfilgrastim biosimilar, referenced on Neulasta. The product, to be sold as Pelgraz, is indicated to reduce the duration of neutropenia, as well as the incidence of febrile neutropenia for adult patients undergoing cytotoxic chemotherapy.

The product is the first pegfilgrastim biosimilar to be authorized by the European Commission and the first Coherus product to be cleared by a regulatory authority.

In its report, the Congressional Budget Office (CBO) notes that it “expects that the bill’s provisions would allow generic drugs (including biosimilar versions of biologics) to enter the market earlier, on average, than they would under current law.” Additionally, CBO said that enacting the legislation would reduce federal spending on prescription drugs.

Today, Sandoz, Cinfa Biotech, and Mylan all revealed that they have received positive recommendations from the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) for proposed pegfilgrastim biosimilars referencing Neulasta.

Brazil benefits from a program, known as the Partnership for Productive Development, that brings together government and the private sector to develop strategic products of interest to the Brazilian health system—including biosimilars of high-cost biologics that account for approximately half of annual drug spending.

The partnership says that it will launch the drug in the European Union on or after October 16, 2018.

The State of California has filed suit against drug maker AbbVie, alleging that the company provided kickbacks to healthcare providers throughout the state to encourage them to prescribe its brand-name adalimumab, Humira, and used a network of registered nurses to mislead patients about the risks associated with the drug.

The bill, introduced in March 2018 by Senator Susan Collins, R-Maine—together with Senators Claire McCaskill, D-Missouri, and Debbie Stabenow, D-Michigan—eliminates so-called “gag clauses” that prevent pharmacies from telling consumers whether they could spend less on their medication by paying out-of-pocket.

On September 13, the European Medicines Agency (EMA) published new, patient-focused materials that aim to make patients aware of biosimilar medicines and how the EMA assures that they are as safe and effective as reference biologics.

Korean drug maker Celltrion says that the FDA’s Oncologic Drugs Advisory Committee (ODAC) will convene to discuss the Biologics License Application (BLA) for CT-P10, a proposed biosimilar rituximab, on October 10, 2018. CT-P10 is already authorized in the European Union, where it was approved under the trade names Rituzena, Ritemvia, Truxima, and Blitzima.

The National Institute for Health Research's Clinical Research Network maintains an active list of more than 800 clinicians—practicing in oncology, gastroenterology, endocrinology, and dermatology—who are interested in delivering trials of biosimilar medicines.

“Biosimilars offer incredible health and economic opportunities in the United States, but unless substantial barriers are surmounted, these opportunities will not be fully realized,” say the report's authors.

At a panel at the GRx+Biosims 2018, Molly Burich, MS, director of public policy for biosimilars and reimbursement at Boehringer Ingelheim, and Melissa Andel, MPP, vice president of health policy at Applied Policy, discussed the impact that US policy developments are having and will continue to have on the biosimilars market.

Alex Brill, CEO of Matrix Global Advisors, gave a presentation during the GRx+Biosims 2018 conference in Baltimore, Maryland that discussed the barriers to increased uptake of biosimilars in the United States, and how to address those issues.

The European Union already has far more approved biosimilars—45 products referencing 15 medicines—than does the United States, but as a newly released report from IQVIA states, the number of European biosimilars available today represents just a fraction of what the market is expected to contain in the coming years, raising questions about the sustainability of the market.

Contrary to experience in the United States thus far, Europe has also seen what Marc-Alexander Mahl, MD, describes as “widespread support for switching biosimilars medicines under the supervision of a healthcare provider.” In fact, regulatory bodies in the EU have spoken out stating that “In our opinion, switching patients from the originator to a biosimilar medicine or vice versa can be considered safe.”

Writing in the European Medical Journal, Anna La Noce, MD, PhD, and Marcin Ernst, MD, MBA, explain that much confusion about switching between biosimilars and reference products in the United States versus in the European Union arises from different uses of the term “interchangeability.”

While the “FDA deservers tremendous credit to enhance and expedite [biosimilars]… there is also a reluctance or hesitation to provide a full account that while the rate of approvals has picked up, the amount of biosimilars on the market [remains low]. Approval is not a synonym for competition," said Chester Davis of the Association for Accessible Medicines.
