Overcoming hurdles to biosimilars cost savings in the US
The US approved its first biosimilar, Zarxio (filgrastim-sndz), on 6 March 2015 [1]. But how can the country overcome hurdles to the cost savings that can be achieved from these drugs? That is a question Sarpatwari and co-authors have tried to answer [2].
Phase I results for candidate adalimumab, etanercept and infliximab biosimilars
Results of phase I clinical studies of candidate adalimumab biosimilar SB5, etanercept biosimilar SB4 and infliximab biosimilar SB2, demonstrated equivalence safety profiles to their originator biologicals in healthy subjects [1-3].

Biosimilars in the US: hurdles to cost savings
In light of the recent approval of the first biosimilar in the US, Zarxio (filgrastim-sndz), [1], Sarpatwari and co-authors look at the hurdles to cost savings for biosimilars in the US [2].
Safety of filgrastim biosimilars following stem-cell transplantation
The safety of granulocyte colony-stimulating factor (G-CSF; filgrastim) biosimilars was compared with that of the originator, Neupogen (Amgen), in a retrospective, single-institution study. Simona Bassi and co-authors at the Guglielmo da Saliceto Hospital in Piacenza, Italy, analysed data from patients with lymphoma or myeloma who had undergone autologous haematopoietic stem cell transplantation (HSCT) at the Guglielmo da Saliceto Hospital.
Approval of biosimilar insulins: regulations across the globe
Insulin analogue patent expiry is likely to mean that biosimilars will be submitted for licensing. In light of this, Heinemann and co-authors reviewed regulatory requirements for biosimilars, notably insulin, in several regions and countries [1].
Biosimilar infliximab offered to French hospitals at 45% discount
A major French hospital group has chosen biosimilar infliximab to treat its patients with rheumatoid arthritis, Crohn’s disease and psoriasis, after major discounts on the drug were offered to the group.
ACR position statement on biosimilars addresses naming and substitution
The American College of Rheumatology (ACR) has issued a position statement on biosimilars, reflecting its views on issues such as interchangeability, substitution, naming and post-marketing surveillance of biosimilars.
Efficacy of filgrastim biosimilars following stem-cell transplantation
The efficacy of granulocyte colony-stimulating factor (G-CSF; filgrastim) biosimilars has been assessed in terms of engraftment following stem-cell transplantation. Time to engraftment was compared following treatment with the originator, Neupogen (Amgen), and with biosimilars in a retrospective, single-institution study.
