Asymchem Services PPQ

Process Validation You Can Trust

Before NDA filing, Asymchem works with customers on the process validation (PV) enabling work (pre-PPQ) that will optimize existing knowledge and deliver a robust commercial process. Using our extensive experience, we can ensure that the resulting process includes the starting material selection and justification, intermediate specification establishment and justification, proven acceptable range (PAR) establishment for parameters, and CPP identification.

During the PV enabling work we focus on impurities and their controls — both process parameter controls and material attribute controls specifications. Our proven template defines the timing and types of activities to guide the PV enabling work.

Underlying all the process activities are the analytical methods. Asymchem has strength in analytical method development and validation, and the analytical teams work hand-in-hand with the process teams to deliver reliable methods for confirming in-process controls, intermediate and final product specifications, as well as stability of intermediates, drug substances, and drug products.

With 40+ successful project validations (including 140+ process steps) over the last 3 years, Asymchem knows the best path to take to fill in gaps in the process knowledge to lead to a successful regulatory filing, process validation, and ultimately commercial manufacture.
