The central figure in any clinical trial is the investigator. But whilst every investigator is a veterinarian, not every veterinarian makes a good investigator. Denny O. Day of VetPharm emphasises the importance of finding the right team of investigators, and then supporting them in the right way. Because finding, training, and motivating veterinarians to be effective investigators will help ensure the success of those trials … and the long-term health and wellbeing of our beloved pets.
