Statement of Work

Integration platform of PATs and digital twin for Lyophilization

This is a combined synopsis/solicitation for commercial products or commercial services prepared in accordance with the format in subpart 12.6, as supplemented with additional information included in this Request of Quotation. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued.

1. INTRODUCTION

1.1 Background

The FDA promotes advanced manufacturing technologies in pharmaceutical production because these technologies can make manufacturing processes more reliable and strengthen supply chains. This leads to faster access to quality medicines for Americans. Digital twins and process analytical technologies (PATs) are key components of this digital transformation. These tools enable process automation, optimization, and performance prediction through real-time data analysis.

The Division of Product Quality Research conducts research on advanced manufacturing to speed up the review of advanced manufacturing technologies and support the adoption of new lyophilization technologies. This acquisition directly supports the Agency's mission to modernize the U.S. pharmaceutical industry. The equipment will enable FDA staff to better understand and identify risks to product quality and patient safety related to digitalization and advanced lyophilization technologies and accelerate regulatory assessment of manufacturing processes that use advanced process analytics. This purchase supports the requirements of the Biosimilar User Fee Act (BSUFA), Prescription Drug User Fee Act (PDUFA), and Generic Drug User Fee Act (GDUFA) programs.
