Mabion starts phase III trial for rituximab biosimilar
Polish biologicals company Mabion announced on 25 November 2014 that it had received the consent of the appropriate regulatory authorities in Croatia, Bosnia and Herzegovina, Serbia and Poland to start a phase III clinical trial for its rituximab biosimilar (MabionCD20) in patients with diffuse large B-cell lymphoma.
Hospira submits application to FDA for epoetin alfa biosimilar
US-based injectables specialist Hospira announced on 12 January 2015 that it had submitted a Biologics License Application (BLA) to the US Food and Drug Administration (FDA) for its epoetin alfa biosimilar Retacrit.
Biocomparable has comparable safety and efficacy to originator erythropoietin in haemodialysis patients
A study of the treatment of patients with chronic kidney disease undergoing haemodialysis with ‘biocomparable’ and originator erythropoietin in Mexico has shown comparable efficacy and safety in terms of changes in haemoglobin levels [1].
Apotex pegfilgrastim biosimilar under FDA review
Canada-based Apotex announced on 17 December 2014 that the US Food and Drug Administration (FDA) had accepted for filing the company’s application for a biosimilar version of Amgen’s Neulasta (pegfilgrastim).
Extrapolation of indications in biosimilars: infliximab
Physicians may not be well informed about the scientific concept underlying the principle of extrapolating* indications for biosimilars. This in turn may lead them to distrust biosimilars, leading to a lower than expected uptake in Europe, especially in extrapolated indications. Members of the European Medicines Agency’s (EMA) Working Party on Similar Biological (Biosimilar) Medicinal Products (BMWP) address these concerns using extrapolation of indications in biosimilar infliximab as an example [1].
FDA advisers recommend approval of filgrastim biosimilar
US Food and Drug Administration (FDA) advisers have voted unanimously to recommended approval for Sandoz’s biosimilar version of Amgen’s Neupogen (filgrastim), a development that could make complex biological therapies more readily accessible in the US.
First infliximab ‘similar biologic’ launched in India
India-based Ranbaxy Laboratories (Ranbaxy) announced on 1 December 2014 that it had launched its infliximab ‘similar biologic’, BOW015 in India. This is the first infliximab similar biologic to be launched in India.
Phase I study shows darbepoetin alfa biosimilar to be well tolerated
Chong Kun Dang Pharmaceutical (CKD Pharma) announced on 18 November 2014 the successful completion of its phase I pharmacokinetics study for its biosimilar darbepoetin alfa product.
Extrapolation of indications in biosimilars: epoetin
Despite a stringent approval process, acceptance of biosimilars in the medical community continues to be low, and especially in extrapolated* indications. Members of the European Medicines Agency's (EMA) Biosimilar Medicinal Products Working Party (BMWP) address these concerns using extrapolation of indications in biosimilar epoetin as an example [1].
Non-biological complex drug concept: experiences with iron sucrose and low molecular weight heparin
When the patent of a classical small molecule drug expires, generics may be marketed if their therapeutic equivalence to the originator drug has been established. The therapeutic equivalence of a drug includes both pharmaceutical equivalence and bioequivalence and do not require formal clinical efficacy and safety studies. The demonstration of therapeutic equivalence then allows for the interchangeability of the generic and originator drug. This approach has so far only been applied to products that can be fully characterized. For more complex molecules, which are difficult to characterize, such as proteins, the demonstration of bioequivalence requires an alternative approach.
