In vivo contract research organizations (CROs) provide outsourced preclinical research services to pharmaceutical and biotechnology companies. Their areas of expertise include the development and execution ofstudies using live animal models to evaluate drug safety and efficacy prior to human clinical trials. By handling these complex in vivo studies, CROs help streamline the drug development process for their sponsor clients.

Regulatory Compliance and Technical Expertise

One of the most important functions that in vivo CROs provide is ensuring regulatory compliance for preclinical studies. They have extensive experience and understanding of guidelines from organizations like the FDA and EMA. CROs are qualified to conduct all aspects of in vivo testing according to Good Laboratory Practice (GLP) standards. This helps generate results that will be accepted by regulatory bodies for IND/CTA approval applications. CROs also employ highly trained technical staff including veterinarians, biologists and laboratory managers to properly design and perform all types of preclinical studies. Their facilities are fully equipped laboratories and vivariums for housing and caring for laboratory animals.

Outsourcing In Vivo Testing Saves Time and Resources

Using an In Vivo CRO allows drug developers to outsource animal testing rather than maintaining these capabilities internally. Building and operating preclinical facilities requires considerable investment of both time and money that is better spent on other areas of R&D. CROs achieve economies of scale by running multiple projects simultaneously. Their extensive portfolios of experience and sophisticated SOPs mean studies can be completed more quickly. Sponsors gain faster access to promising compounds as go/no-go decisions can rely on high-quality preclinical data earlier in development pipelines. CROs also take on the responsibility of procuring, housing and euthanizing animals which pose compliance and ethical challenges for smaller companies.

Broad Range of Preclinical Testing Models and Services

In vivo CROs are equipped to provide a comprehensive spectrum of preclinical services. This includes efficacy and safety pharmacology assessments in various disease models like cancer, diabetes, CNS disorders and more. They are set up for pharmacokinetic analyses determining absorption, distribution, metabolism and excretion of new molecules. Toxicology studies evaluate the maximum tolerated dose, identify target organs of toxicity and establish a safety profile. Other specialized preclinical capabilities include formulation development, device testing, veterinary services and more. CROs also offer flexible project management from protocol design through reporting and statistical analysis of results.

Worldwide Reach and Customization Options

Leading in contract research organizations operate facilities across major regions to provide sponsors with a localized partner. This helps reduce transportation costs and complies with any geo-fencing requirements. As the global pharmaceutical industry grows, having preclinical testing capabilities internationally is important. Most CROs also offer customization and specialized services tailored for individual project needs. They work closely with sponsors throughout the discovery and development process providing strategic recommendations based on extensive industry experience. CROs deliver high quality results through their standardized processes while maintaining flexibility to problem-solve unique challenges.

Examples of Key In Vivo CROs

Some of the largest and most prominent in contract research organizations contracted for preclinical services include:

- Charles River - Over 50 laboratories worldwide conducting efficacy, safety and toxicology studies. Offer broad range of disease models and specialized testing.

- Envigo - Operate over 70 facilities with in vivo and associated laboratory services. Specialize in pharmacology, toxicology and specialized model development.

- Eurofins - Network of preclinical CROs across North America, Europe and Asia/Pacific. Provide GLP toxicology, ADME, safety pharmacology testing.

- Wuxi AppTec - Large Chinese CRO with US and EU locations. Experts in biosimilars development and specialized models like those for immuno-oncology.

- Syngene - Indian CRO with pharmacology and toxicology testing capabilities. Affordable preclinical solutions for virtual/global pharma companies.

- Covance - A CRO division of LabCorp providing preclinical and clinical research services worldwide. Particularly strong in transgenic model development.

Using well-respected in contract research organizations streamlines the complex process of investigating new molecules in animal models. Their integrated services and regulatory compliance help advance valuable candidates into human trials more quickly and cost-effectively. Outsourcing preclinical testing to experienced global providers remains an important strategy for ongoing pharmaceutical innovation.
