Eculizumab is used to treat paroxysmal nocturnal hemoglobinuria (PNH), a rare bone marrow disorder in which expansion of certain hematopoietic cells that lack a key protein cause the destruction of red blood cells, or hemolysis.

A phase 1 study compared pharmacokinetics (PK), pharmacodynamics (PD), safety, and immunogenicity between SB12, a proposed eculizumab biosimilar, and EU and US reference products (Soliris) in healthy adults.

Abstracts from the European Hematology Association Congress 2022 confirmed comparable safety and effectiveness profiles between 2 rituximab biosimilars and the reference product (Rituxan) in patients with large B-cell lymphoma.

Abstracts from the 2022 European Hematology Association (EHA) Congress presented positive data for 2 biosimilar candidates referencing Soliris (eculizumab).

In a pharmacokinetic (PK) and pharmacodynamic (PD) trial in healthy participants, Samsung Bioepis' SB12 eculizumab biosimilar candidate demonstrated equivalence to Soliris, the reference product.

Xbrane Biopharma of Stockholm, Sweden, said its next biosimilar candidates will target the demand for oncology and hematology therapeutics.

During this week’s 61st meeting of the American Society of Hematology (ASH), researchers reported on eculizumab, a prospective biosimilar, and the long-acting ravulizumab.

Amgen is developing a biosimilar of the drug, ABP 959, and during last week’s 24th Congress of the European Hematology Association, held from June 13-16 in Amsterdam, the Netherlands, researchers reported on findings from a phase 1 trial of the proposed product.

The American Society of Clinical Oncology (ASCO) and the American Society of Hematology (ASH) first published their guidelines on erythropoiesis-stimulating agents (ESAs) in cancer care in 2002, with updates in 2007 and 2010, and the new update is the first to address biosimilar epoetin alfa.

On the heels of the FDA approval of Celltrion’s rituximab biosimilar Truxima in November 2018, December saw the publication of a variety of new data on biosimilars used in hematology.

Celltrion’s CT-P10, a biosimilar rituximab that was FDA approved under the brand name Truxima in November 2018, is already in wide use for a host of indications in many regulatory territories. During this week’s 60th Annual Meeting and Exposition of the American Society of Hematology in San Diego, California, multiple research teams are reporting data that underscore the safety and efficacy of CT-P10 in hematological conditions.

In 2016, the Saskatchewan Cancer Agency switched from the brand-name filgrastim, Neupogen, to a biosimilar, Apotex’s Grastofil, for stem cell mobilization prior to autologous stem cell transplants. In a study presented at the American Society of Hematology’s Annual Meeting, researchers sought to determine the safety and efficacy of using a biosimilar for this setting.

Biosimilars of eculizumab, which have the potential to reduce costs for both patients and the healthcare system, have been eagerly awaited, yet many drug makers are developing novel anti-C5 agents.

In a recently published editorial in The Official Journal of the World Federation of Hemophilia, author Angela Thomas, MB, PhD, discusses the advancements in hemophilia treatment as well as the place biosimilars may or may not have in reducing the cost of care.
