RT Journal Article SR Electronic T1 PDA PAC iAM 2017 Survey on Post Approval Change Is the regulatory environment hindering much needed innovation in the Pharma Industry? JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP pdajpst.2017.008219 DO 10.5731/pdajpst.2017.008219 A1 Seymour, Melissa YR 2017 UL http://journal.pda.org/content/early/2017/08/16/pdajpst.2017.008219.abstract AB As part of the effort to identify, assess and address current barriers to PACs, the PDA administered a global, blinded, cross-functional survey to document industry experience with PACs in the current global regulatory environment, and to better understand the regulatory complexity and burden on the industry. The survey interrogated on specific points related to annual volume of PACs, reasons, time commitments/cycle time, impact of regional differences on change implementation, current use of tools (e.g. PACMPs), impact on supply chain complexity (e.g. inventory, variants to manage, non-compliance to filings, drug shortages), manufacturing innovation, and resources needed.
