Sonia T. Oskouei, PharmD, vice president of innovation and solution development at Premier Inc, discusses how anticancer biosimilars have played a role in oncology in 2019.

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

While biosimilars approved by regulators have been shown to have no clinically meaningful differences from their reference products, this week, during the San Antonio Breast Cancer Symposium, held in San Antonio, Texas, researchers will report reassuring data for biosimilar trastuzumab, Ogivri, showing that the combination of the biosimilar with pertuzumab is highly similar to the combination of the reference drug with pertuzumab.

Increased spending on new oncology and autoimmune drugs was partially offset by a decline in price growth and the continued increase in the use of generic drugs, according to a recent report from CMS about national healthcare spending in 2018.

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.

Lee Schwartzberg, MD, FACP, executive director, West Cancer Center, discusses what oncologists have learned from experience with supportive care that can be applied to adopting anticancer biosimilars.

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.

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.

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.

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.

Sonia T. Oskouei, PharmD, vice president of innovation and solution development at Premier Inc, discusses how biosimilars have impacted innovation in oncology.

During the European Society for Medical Oncology Asia Congress 2019, held last week in Singapore, a research team led by Binghe Xu, MD, PhD, department of medical oncology at the Cancer Hospital Chinese Academy of Medical Sciences, Beijing, China, reported that the biosimilar met its primary end point of best overall response rate at week 24.

This week, a study from Spain retrospectively compared direct costs of intravenous and subcutaneous reference rituximab in the setting of lymphoma, taking into consideration drug costs, pharmacy costs, and chair time-related costs at a single center in 2017. They also conducted the same analysis using the costs of biosimilar rituximab.

Samsung Bioepis announced Tuesday that the FDA has accepted for review the company’s Biologics License Application (BLA) for SB8, a proposed bevacizumab biosimilar referencing Avastin. The biosimilar developer submitted the BLA in September.

Novartis has confirmed in an email to The Center for Biosimilars® that it has launched Sandoz’s pegfilgrastim biosimilar, Ziextenzo, in the United States. According to Novartis, the wholesale acquisition cost (WAC) for Ziextenzo is $3925, or an approximate 37% discount off the WAC for the reference product, Amgen’s Neulasta.
