The ranibizumab biosimilar XSB-001 (Ximluci) demonstrated biosimilarity to the originator (Lucentis) in a phase 3 trial in neovascular age-related macular degeneration (nAMD).

Sarfaraz K. Niazi, PhD, examined the new FDA guideline that acts as an invitation to biosimilar developers to decrease the cost of testing, potentially opening the door for companies to reduce nonclinical testing of biosimilars entirely.

In his latest column, Sarfaraz K. Niazi, PhD, went over some best practices for implementing innovative solutions for the purposes of streamlining biosimilar development.

Authors of a new in vitro study said Sanofi’s biosimilar SAR341402, approved in June 2020 by the European Medicines Agency for use in insulin pumps, had similar stability compared with the originator under stress conditions in their experiments.

Although the FDA has consistently edited its testing guidelines for biosimilar developers over the years, clinical testing is still very expensive and time-consuming. Sarfaraz K. Niazi, PhD, offers the FDA and companies a plan of action for reducing clinical testing expenses for biosimilar products.

A phase 1 clinical trial in China comparing the tocilizumab biosimilar candidate LZM008 to the reference product (Actemra) found pharmacokinetic (PK) parameters within the bioequivalence margins and similar immunogenicity and safety in healthy participants.

The authors of what they say is the largest and longest follow-up study comparing the trastuzumab biosimilar SB3 to the reference product (Herceptin) in HER2-positive breast cancer found “no clinically meaningful difference” between the biosimilar and the reference product.

At the 2023 Association for Research in Vision and Ophthalmology Annual Meeting, Samsung Bioepis shared comparable safety, efficacy, and immunogenicity data through 1 year between its aflibercept biosimilar (SB15) and the originator (Eylea).

Sarfaraz K. Niazi, PhD, dives into how pharmacodynamic (PD) markers may be better than clinical efficacy testing for predicting whether a biosimilar is equally as safe and effective as its reference product, in his latest column.

A long-term follow-up of a phase 3 study comparing ranibizumab biosimilar SB11 to the reference product (Lucentis) in neovascular age-related macular degeneration (nAMD) found the similarity in efficacy end points reported early on was maintained through 52 weeks.

The misconceptions about disposable bioreactors' lifecycle are gone; the era of hard-piped, giant, stainless-steel tanks for biosimilar development is history now, according to Sarfaraz K. Niazi, PhD, in his latest column.

Celltrion Healthcare shared data from a phase 3 clinical trial confirming that its omalizumab biosimilar had comparable safety and efficacy to the reference product (Xolair).

Sarfaraz K. Niazi, PhD, explains and analyzes the FDA's changes for the Biosimilar User Fee Act (BsUFA) meetings and how they influence the efficiency of the biosimilar approval process in the latest installment of his bimonthly column.

In the wake of adalimumab biosimilars hitting the US market, Sophia Z. Humphreys, PharmD, MHA, BCBBS, of Sutter Health, hyped up the current biosimilar market trends and the other products coming down the pipeline during her talk at the Festival of Biologics.

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.
