Our data audits will determine the most cost effective route to obtain a Marketing Authorisation in your chosen market and confirm the optimum regulatory strategy. Cyton has experience with a wide range of applications from novel drug substances to generics and we are familiar with the data requirements for all veterinary dosage forms. Our gap analysis reports include a high level overview of deficiencies in your data package and a more detailed analysis.

Preparation of Detailed and Critical Summaries (formerly Expert Reports)

Our technical experts have an in-depth knowledge of pharmaceutical manufacturing.  Cyton will prepare Critical Summaries to support the chemistry and manufacturing data for new applications, Type II variations and renewals.  Using our detailed knowledge of current regulatory guidance we can help to justify the data presented, whilst also identifying any deficiencies, in preparation for the assessment process.
