Maintaining clinical and regulatory data and documents is critical to bringing a therapeutic product to market and keeping it there. Failure to adequately produce and manage clinical records can be very costly. Of 5000 to 10,000 new chemical entities, five will go to the clinic, but just one will gain approval.
