Clinician biosimilar prescribing habits and need for education

Biosimilars/Research | Posted 22/03/2019

At present, biosimilar prescribing and clinical use remain contingent on individual healthcare provider preferences. Although novel legislation and policy continue to promote biosimilar drug development, clinician hesitancies curtail biosimilar use in practice, thereby limiting overall market uptake. Findings from a recently published systematic review indicate that clinicians in Europe and the US do not primarily support the use of biosimilars as safe and effective therapies in patients already receiving originator biological treatment [1].

Being largely asymptomatic the silent thief can get away with insidiously stealing the patient’s bones until, as a result of the relentless bone loss, fragility fractures inevitably occur. The first, so-called sentinel fracture is the forerunner of the devastating fracture cascade as any prior fracture translates into a two- to four-fold increase in the risk of sustaining a subsequent one within one year [1].

EMA continues to be open to alternative clinical development strategies for biosimilars

Biosimilars/Research | Posted 18/01/2019

In the European Union (EU) and other highly regulated markets, companies need to prove the similarity of proposed biosimilars to the established reference product for gaining market authorization. European regulators recommend using a stepwise approach whose first steps consist of a demonstration of similarity at the analytical level and via non-clinical studies. In addition, as a later step, clinical studies are an important source of additional evidence.

Safety of biosimilar infliximab in pregnant women with IBD

Biosimilars/Research | Posted 11/05/2018

Introduction of the first biosimilar infliximab (CT‑P13, Remsima/Inflectra) for the treatment of inflammatory bowel diseases (IBDs) was aimed to reduce the healthcare cost burden and to increase the number of treated individuals with similar treatment results. Shortly after CT‑P13 has been authorized for usage in clinical practice, many concerns arose due to the fact that the principle of extrapolation of limited clinical results had been applied to the biosimilar, which led to approval of the biosimilar in all the indications of the originator biological (Remicade). However, these concerns have proved to be unfounded, as subsequent studies have confirmed the similar efficacy, safety and immunogenicity of CT‑P13 and Remicade in the general IBD population [1].

Safety surveillance of bevacizumab biosimilar (Bevax) in Argentina

Biosimilars/Research | Posted 15/02/2019

Benefit-risk evaluations are mandatory throughout the life cycle of a therapeutic agent, to guarantee efficacy for the authorized indications without an unacceptable incidence of adverse effects. This monitoring can be carried out using pharmacovigilance (PhV) procedures, which are vital in the identification and prevention of adverse drug reactions (ADRs). Due to the inherent variability of bioproduction, this is of paramount importance for biological products, including biosimilars.

Switching from reference products to biosimilars: the European perspective

Biosimilars/Research | Posted 30/11/2018

The number of biosimilars receiving marketing authorization has grown steadily over the past several years [1, 2] and is expected to continue growing in the future.
