What to look forward to in GaBI Journal, 2013, Issue 2

The first of two Letters to the Editor is from Ms Gaspani and Ms Milani expressing their concerns about the lack of clear regulatory guidelines for approval of liposomal generic formulations. Liposomal products are only one and perhaps some of the best-characterized example of non-biological complex drugs (NBCDs). NBCDs while not having a biological source…

Abstract: Current regulations do not require a given biosimilar to remain similar to its reference biological over time. However, two products that were initially deemed biosimilar or interchangeable could each undergo unique patterns of drift and evolution in their manufacturing processes (divergence), ultimately resulting in two products that would be no longer biosimilar. In cases…
