Pfizer Consumer Healthcare, Richmond, VA, Consultant-Manager, 2009 - 2011

Regulatory Analyst, Project Manager and Consultant for the NDA and Monograph Products

  • Provided scientific and regulatory assessment of a variety of manufacturing plant post-approval change controls and communicated information to stakeholder affiliates in key global markets: U.S., Canada, Asia, Europe, Middle East, Central American, and South America, (with successful, $1.6 billion in sales).
  • The affiliates communicated with their health authorities (HA), as advisor briefed on the tests and documentation required for products to be marketed in their home countries.

Completed Reports

  • Plant was changing their supplier of PET resins and colorant for bottles of OTC cough syrups. Line trials and stability studies were required in the plant. Communicated with Middle East affiliates: HA required prior approval before shipments allowed. Required validation report, accelerated 3 mo. stability data with commitment for 1 year under ambient conditions, and updated finished product and bottle specifications.

One lot to be stored horizontally so that the product contacts the container/closure system. Other countries only required HA notification of the plant change and shipments could start after 30 days. Products were shipped as per schedule.

  • Cost savings: a contract vendor previously prepared glycerin 95% by diluting 99.7% with water and shipping in drums (for OTC cough syrups for the Mexican and LATAM market). Pfizer management decided that it would no longer use this contractor. The manufacturing process would be to start from bulk 99.7% and dilute with water in the plant. Identified the risk assessment of this change to the Mexican/LATAM affiliates. Satisfactory accelerated stability data pre- and post-change showed that no long-term stability tests or validation data would be required as the formulation did not change. The products were approved to ship to the Mexican and LATAM market with no HA notification required.
  • A change control was initiated due to a third-party vendor in South America manufacturing bulk soft gels for shipment back to the US for packaging. The gelatin in the formulation was actually a combination of beef and pork (for improved tensile strength).
  • Authored Submission-Ready Regulatory Documents for electronic filing for different country markets. Managed renewals and new product registrations in different countries. Obtained CEPs for APIs and provided documents for free sales certificate (CPP) from FDA.
  • Updated various product registration databases for documentation management for 130 products to ensure QA compliance.
  • Provided input to the Raw Materials testing team on which analytical tests are critical to the quality of the finished products. This reduced testing initiatives that maintained quality and provided cost savings to Pfizer.
  • Reduced stakeholder complaints by 20% by processing change controls efficiently.
