Transforming possibilities into breakthroughs – saving lives with science, ethics, and care.
Who We Are
Charles River provides essential products and services to help pharmaceutical and biotechnology companies, government agencies and leading academic institutions around the globe accelerate their research and drug development efforts. Our dedicated employees are focused on providing clients with exactly what they need to improve and expedite the discovery, early-stage development and safe manufacture of new therapies for the patients who need them.
Global Reach
A network of 130+ facilities in 20 countries, employing 21,000 experts dedicated to early-stage drug development to
advanced therapies, including the development of more than 80% of FDA-approved drugs, and all COVID-19 vaccines.
---Commitment to Humane Care
Before a drug can be evaluated in the clinic on humans, global regulatory agencies require animal research to ensure patient safety. Animal research is fundamental to foundational scientific research and understanding how to prevent and treat emerging infectious diseases, including the successful development of every COVID-19 vaccine as well as treatments for cancer, diabetes, and a myriad of rare diseases. Charles River's work is an essential component of the research that has led to these discoveries and has played a vital role in medical advances for humans as well as animals. Charles River is deeply committed animal welfare and exceeding international standards for the care of research models under our stewardship.
We are committed to the 3Rs (Replacement, Reduction and Refinement) and, when possible, our goal is to reduce the number of animals used. Additionally, we partner with customers to develop study designs that adopt the philosophy of the 3Rs, including the use of in vito studies accepted by international authorities.
Mauritius Presence
Through Noveprim, Charles River is the largest U.S. investor in Mauritius's agro-industrial and biotech sector, supporting research capacity and creating sustainable jobs.
--Charles River's Purpose
Our Mission
At Charles River, our purpose is clear-to create healthier lives through world-class science and an unparalleled portfolio of solutions. We are driven by the patients who rely on the treatments we help bring to life, the well-being of the animals in our care, and our unwavering commitment to people and the planet.

--The Essential Role of Mauritian Primates
Why They Matter
The use of non-human primates (NHPs) is fundamental to foundational scientific research and understanding on how to prevent and treat emerging infectious diseases, including the successful development of every COVID-19 vaccine as well as cancer, diabetes, and myriads of rare diseases. Before a drug can be evaluated in the clinic on humans, the FDA often requires testing in two animal species, including one non-rodent species, to ensure patient safety. Because of their close genetic, physiological, and behavioral similarity to humans, NHPs are often the only relevant animal models for critical translational research.
--Impact on Human Health
Mauritian primates have been critical to breakthroughs in diabetes reversal, organ transplant innovations, and COVID-19 vaccine development - contributions that save millions of lives globally.
