Colchester Research Group

Today's Research. Tomorrow's Cure.

The Colchester Research Group was established by the owner and founder, Dr. Linda Ferguson in 2002. CRG has been bringing research to the Truro and surrounding areas for the purpose of expanding knowledge of medical illnesses and improving treatments. Our network of outstanding physician investigators are committed to providing superior service to our patients and sponsor companies with which we work.


Our highly qualified team consists of physicians, registered nurses, clinical research co-ordinators and office support staff under the direction of Principal Investigators. All of our staff members are provided with ongoing GCP training including in-house training, Investigator meetings, conferences and circulation of GCP related articles.


Over the last twenty years, Colchester Research Group has conducted numerous national and international trials. Our main focus is conducting trials for new medications in a full range of medical conditions. We also have a special interest in large vaccine trials and we have extensive experience in Phase IIa, IIb, and III and phase IV pharmaceutical trials.


The Colchester Research Group played a prominent role in the H1N1 pandemic being the highest recruiting site in North America for the Phase I/II trial ensuring the safety and efficacy of the H1N1 vaccine. We have also contributed to the trials associated with the development of the HPV vaccines designed to prevent cervical cancer – vaccines now available to the public worldwide. CRG will also contribute during COVID-19 through trials to be conducted in the future.
