Safety Assessment Services

Your Success is Our Biggest Achievement

Whether you are working on an innovative small molecule or an advanced biologic drug candidate, you can rely on our Safety Assessment Team to use our proven expertise to develop a program that meets your specific needs. One that is fully compliant with the U.S. Food and Drug Administration (FDA), Organization for Economic Co-operation and Development (OECD) and the National Medical Products Administration (NMPA) Good Laboratory Practice (GLP) requirements. Your studies are conducted in a fully AAALAC (Association for Assessment and Accreditation of Laboratory Animal Care) accredited state-of-the-art facility and overseen by Testing Facility Management (TFM) with over 170 years of combined experience. The studies we’ve conducted have supported more than 600 Investigation New Drug (IND) applications and New Drug Applications (NDA) worldwide.

A fundamental principal of WuXi AppTec is to ultimately see your success as our biggest achievement. We are passionate about your program and understand the importance of meeting drug development milestones, giving you the most robust data and keeping your drug on the path to success. As your scientific and business partner, we will go above and beyond to ensure we complete your study as planned, providing you with a quality product on time, every time.

Full-Scale Testing Platform

For nearly a decade, the Toxicology Team has provided a full-scale testing platform for clients at all stages of drug development. Leveraging the translational expertise of our diverse team of scientists, we have completed thousands of discovery, IND- and NDA-enabling studies for our global clients, while maintaining a nearly perfect record of on-time delivery.

Whether you need a four week rodent study to support an IND filing or a two year carcinogenicity study for an NDA, all of your safety assessment studies will be conducted in our ultra-modern 580,000 square foot facility comprising 256 animal rooms.

On-Time Data and Report Delivery

Real Time Data Access

By building a service entirely around your needs, we can provide a single program that will include one Standard for Exchange of Nonclinical Data (SEND) compliant master dataset, reduce test sample volumes and minimize the need for potential duplicative animal testing. We also design each program with the flexibility needed to adjust to changing timelines, while still securing your original deadlines. This model has consistently performed and maintained a 99% on time delivery of audited draft reports.

To give you complete visibility of the testing process, our monitoring systems were carefully designed to provide real time data access and regular communication with your dedicated Project Managers. By working closely together, we pool our joint knowledge and scientific expertise to spot potential risk factors and avoid delays before they can adversely impact timelines.

WuXi AppTec’s safety assessment facility in Suzhou, China, currently has over 600 staff and are also among the most qualified globally, both in education and experience in the field of drug development. Approximately 25% have graduate degrees, and the Senior Management team has gained significant experience internationally. Our Study Directors hold certifications from Diplomate of the American Board of Toxicology (DABT) and the European Registered Toxicologist (ERT) and bring a wealth of knowledge to every program. The Toxicology Team has conducted over 5,000 safety assessment studies since January 2011.
