'Pharmed' goats seek drug license

 Imagine you could get life-saving
 medicines from milking a common
 farmyard animal.

 That idea moves a step closer to
 becoming a reality this week, as the
 European Medicines Agency (EMEA)
 considers the final stages of an
 application to license a natural human
 protein extracted from the milk of
 goats.

EU funding for GM plant vaccines
 European scientists have launched a project
 to make pharmaceutically useful products in
 genetically modified crops. The consortium,
 called Pharma-Planta, wants to produce
 vaccines and other treatments for major
 diseases, such as HIV/Aids, rabies and TB.
 The EU has put 12 million euros (£8m) into
 the project, which hopes to start clinical trials
 by 2009.
 The first product, possibly grown in maize, is
 likely to be an antibody that can be used to
 block HIV transmission.
 It would be incorporated into a microbicidal
 cream that could be used in the vagina.

The extent of the studies to demonstrate comparability will
  depend on:

 The production step where the changes are introduced
 The potential impact of the changes on the purity as
  well as on the physicochemical and biological properties
  of the product, particularly considering the complexity
  and degree of knowledge of the product (e.g. impurities,
  product related substances)
 The availability of suitable analytical techniques to
  detect potential product modifications and the results of
  these studies, and
 The relationship between quality attributes and
  safety and efficacy, based on overall non-clinical and
  clinical experience.

Guideline on Similar Biological Products (CPMP/437/04)
Product-specific guidelines
A similar biological medicinal product is defined by
 characteristics:

 related to the molecule (including product related
  substances/impurities), and
 related to its process (which may affect molecular
  characteristics and includes process related impurities).
The Applicant should demonstrate the consistency and robustness
of his own process according to existing guidelines.

 ADVATE is a modification of Recombinate (approved on 12
  May 1993)
 Both drug substances are produced by the same CHO cell line
 Protein free production process. Modifications to the
  fermentation, the purification process and the drug product
  formulation were introduced
 A S/D viral inactivation step was also introduced

 Both quality and PK/PD studies showed comparability
 between these two products
 The applicant submitted an application comprising
  pharmacokinetic, clinical efficacy, and safety data required for
  a completely new product.
 Primary objective of the pivotal study: Advate is bioequivalent
  to Recombinate.
 A stepwise approach was followed. Results indicated that:
 i) Recombinate and Advate pilot scale are bioequivalent
 ii) Advate pilot and Advate commercial scale are bioequivalent
