Animal studies are the gold standard for preclinical and translational studies of gastrointestinal (GI) disease. Although there are now specialized cell lines and "organs-on-a-chip" that provide in vitro platforms that can be used for drug selectivity and specificity studies, only whole-animal physiology can approximate clinical pathology and the effects of novel therapeutics.

Creative Bioarray has extensive experience in GI studies for a variety of indications. Our expertise in GI preclinical research and consistent track record of success as a full-service CRO ensures the flexibility to adapt to the unique needs of each trial. Our disease models are suitable for testing disease-modifying drug or compounds acting on symptomatic effects. Depending on your needs, it is possible to perform classical, oral (PO), intravenous (IV), intraperitoneal (IP) or intrarectal administration.
