A Phase 2 Clinical Trial is the second stage of clinical trials for a new drug. Phase 2 trials begin once a drug has passed Phase 1 safety trials. Phase 2 testing examines the EFFICACY of the drug in treating a specific condition or symptom. Essentially, it tries to answer the question—does this treatment WORK?
How Many Animals Participate in Phase TWo Clinical Trials?
Phase 2 clinical trials can involve a small group of animals or up to several hundred. For our Phase 2 epilepsy trial, Dr. Stephanie McGrath and her team at Colorado State University’s School of Veterinary Medicine and Biomedical Sciences enrolled 26 healthy dogs.
Are There Safety Protocols in Place to Make Sure Study Participants are Well Treated?
A well designed Phase 2 study will keep the animal’s welfare at the forefront at all times. Certainly any study that ABSC sponsors will ensure that dogs are well treated—after all, we’re in this business to help animals live healthier and more comfortable lives! Colorado State University has a committee that oversees animal welfare for all of their clinical testing.
What Happens After Phase 2 Testing? Is there a Phase 3?
Once Phase 2 testing is complete, researchers will move to Phase 3, which will look at larger populations of animals and last longer. They often compare results with the new medication versus results achieved using older, more established treatments.« Back to Glossary Index
