Bovine Pituitary Extract (BPE)

 

We note that –b(4)--- sources for bovine pituitary extract (BPE) are included in 
the Quality Material Specifications (QMS):

 

[                                         b(4)                                   
                  ]

 
  In BLA section 3.2.S.2.3.1.2 (Manufacture of Bovine Pituitary Extract), it 
  states that pituitary glands from cattle sourced from –b(4)------- “will be 
  used in the         --b(4)-----------------------------------------”. Please 
  clarify what source is currently utilized for BPE manufacture, and if not 
  already using material sourced from the   --b(4)-------- cattle, define when 
  this change will occur.

 
  ----b(4)--- 
  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 

---b(4)-----------------

 
  Regarding the –b(4)-------------- that is used for Apligraf manufacture, we 
  have not been able to locate information regarding the methods used for 
  monitoring the –b(4)-- used for collection of this reagent and the procedures 
  that are followed to prevent its contamination with prohibited materials 
  during collection. Please provide this information.
