Inflammatory Bowel Disease: Current Status and Future Perspectives

By Maxim Kosov

MD, PhD, PSI Senior Medical Advisor

In today’s crowded IBD clinical trial landscape, it can be difficult to complete your study as quickly and efficiently as possible. Being aware of the unique challenges that come with IBD trials can help you prepare and pivot more effectively when complications arise. In this white paper, Dr. Maxim Kosov, Senior Medical Advisor at PSI, breaks down recent trends in IBD clinical research, including insights into patient recruitment and retention.

Inflammatory Bowel Disease: Current Status and Future Perspectives offers insights into recent trial and research developments that will most impact study design and operationalization for various IBD therapies and indications. Download our new white paper to learn about:

  • IBD epidemiology, patient risk factors, and cost drivers
  • Current diagnostic and treatment methods
  • Common clinical trial challenges and methods for patient enrollment and retention

Executive Summary 

Inflammatory bowel disease (IBD) is an umbrella term that covers several clinical conditions, with two of them being the most common: Ulcerative Colitis (UC), which is limited to the colonic mucosa; and Crohn’s Disease (CD), which potentially affects any segment of the gastrointestinal tract from the mouth to the anus.

Both UC and CD are chronic, lifelong inflammatory diseases with a pattern of flare-ups and remission. While we have learned a lot about the predisposing factors, clinical symptoms, pathways, pathology, and genetics, the exact cause of these diseases remains unknown. The number of clinical trials aimed at the discovery of novel therapeutic options is increasing annually. But with more trials comes increasing complexity and challenges.

As a result, while we have come a long way in developing options to treat the symptoms of the diseases, we do not yet have a definitive treatment or cure. These diseases remain highly debilitating and, while no longer fatal in industrialized countries with the current state of medicine, continue to have a negative impact on the overall quality of life for the patient. This white paper will discuss UC and CD’s respective epidemiology and risk factors, current diagnostic and treatment approaches, and considerations for designing effective clinical trials.
