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].
