EU Defends Plans To Keep 'PUPSIT' Testing In Revised EU GMP Annex 1

An EU regulatory official is undeterred by pleas from industry to modify a requirement that manufacturers conduct pre-use, post-sterilization integrity testing of filters for sterile drugs under EU GMP Annex 1. The original annex required PUPSIT testing and the revision also is expected to require it. The revised annex has been repeatedly delayed, and now is expected early next year.
