At the Festival of Biologics, Hillel Cohen, the executive director of scientific affairs at Sandoz, shared the current body of literature on biosimilar-to-biosimilar switching, saying that although there isn’t much published data, the vast real-world experience demonstrates the safety of this type of medication switch.

At the Festival of Biologics, Juliana (Julie) Reed, executive director of the Biosimilars Forum, warned that without changes to encourage biosimilar uptake, companies will begin to ask the big question: Are biosimilars worth investing in?

At the American Academy of Dermatology annual meeting, Samsung Bioepis shared positive results from a phase 1 study comparing its ustekinumab biosimilars (SB17) with the reference product (Stelara).

The FDA's new artificial intelligence (AI)-based modeling on characterizing protein aggregation could directly impact the safety assurance of biosimilars and other therapeutic proteins.

A white paper touting biosimilar successes in the United States reasoned that increased market competition will help improve utilization rates, generate substantial savings, and encourage payers to cover biosimilars.

In part 2 of this 2-part series, Ivo Abraham, PhD, chief scientist of Matrix45 and a professor at the University of Arizona, continued to examine guidelines from the World Health Organization (WHO) and how they view interchangeability and animal study requirements.

At the European Crohn’s and Colitis Organisation congress, Celltrion Healthcare shared positive safety and efficacy data on maintenance therapy including its infliximab biobetter allowing for subcutaneous administration, Remsima SC.

Authors of a review of safety results across indications and study designs on the epoetin alfa biosimilar HX575 concluded that HX575 “has repeatedly demonstrated long-term safety” in all approved indications in both clinical trials and real-world studies.

Phase 3 study findings support a proposed natalizumab biosimilar (PB006) as the first biosimilar alternative to reference natalizumab (Tysabri) for treatment of relapsing-remitting multiple sclerosis (MS).

Ivo Abraham, PhD, chief scientist of Matrix45 and a professor at the University of Arizona, details how biosimilar guidelines from the World Health Organization (WHO) have changed over time and whether those changes are beneficial for biosimilars in part 1 of this 2-part series.

The American College of Rheumatology (ACR) steadfastly supports the availability of safe and effective treatments for patients at the lowest cost possible, and underscores the necessity of scientific rigor for biosimilar use and approval.

Jacqueline Corrigan-Curay, MD, JD, principal deputy center director of the FDA's Center for Drug Evaluation and Research, gave a keynote presentation at Access 2023 on how the Biosimilar User Fee Act and the Generic Drug User Fee Act have developed over the last year.

In theory, by offering a lower-cost treatment option, biosimilars would help drive access for countless patients who simply could not afford the brand-name biologic. However, biosimilars have also encountered the harsh realities of the US health care system and its market forces.

Biocon Biologics and its partner Viatris received a complete response letter (CRL) for their biosimilar referencing Avastin (bevacizumab), the second CRL for the companies in 2023. The news comes as Biocon publishes increased revenues for biosimilars and generics.

The proposed omalizumab biosimilar KA (Shanghai Taiyin Biotechnology) demonstrated similar analytical characteristics, in vitro biological activity, and pharmacology and toxicology in animals compared with the originator (Xolair), according to investigators.

The first phase 4 postmarketing surveillance study for SB4 in South Korea as the first approved biosimilar of etanercept demonstrated comparable effectiveness and safety to previous SB4 evidence.

A phase 3 analysis found that CKD-701, a ranibizumab biosimilar candidate developed by CKD Limited, has comparable clinical efficacy and safety with the reference product (Lucentis) in patients with neovascular age-related macular degeneration (nAMD).

Sophia Z. Humphreys, PharmD, MHA, BCBBS, of Sutter Health in Sacramento, California, details the regulatory decisions from 2022, what's to come in 2023, and how the US biosimilars market is expected to shift over the next 5 years.
