Our Super Specialty: Clinical Trials

As part of an academic medical center, we lead our field in developing new and better treatment options for all colorectal patients. In an effort to offer cutting-edge care, we participate in clinical trials exploring new devices, medications and technologies with the potential to achieve better outcomes, minimize trauma and improve quality of life.

The Global Center currently leads several innovative trials to help shape the management for colorectal disease conditions and inflammatory bowel disease for the future. This includes novel therapies, endoscopic techniques and perioperative pathways that have not previously explored and could completely change how these conditions are managed.

Key Trials

Boom-IBD clinical trial

Breakthrough treatments and clinical trials do not always mean new technology but entirely new applications of existing technology. The Global Center at Columbia enrolled the first patient in a nationwide study evaluating sacral nerve stimulation to treat Crohn’s disease and ulcerative colitis using a small implantable medical device. The device uses gentle electrical impulses to activate a nerve pathway in order to reduce inflammation and improve IBD symptoms, and has been granted Breakthrough Device Designation by the FDA for the treatment of Crohn’s disease and ulcerative colitis.
After completion of the early feasibility phase, the Boom-IBD trial is gearing up for a pivotal study.

PATENT-B clinical trial

This study aims at determining the safety and efficacy of GIE Medical’s ProTractX3 TTS DCB for the treatment of recurrent benign bowel strictures. The goal of this technology is to provide immediate relief via balloon dilation and create lasting durable results.

Anal Fistula trial

Our surgeons take a comprehensive approach to anal fistula care, exploring ways to improve outcomes beyond the technical aspects of the procedures. On the basis of an innovative study on microbiome, our providers were the first to propose the idea that there may exist certain enteric bacteria associated with a higher recurrence rate following anal fistula repair. While this research is still ongoing, its findings could invoke a biologic basis for surgical failure following surgery for fistula and inform a personalized medicine approach to antibiotic decontamination of the fistula site prior to surgery.
