Similar But Different: Regulatory and Operational Considerations for Biosimilar Clinical Development in IBD  

The rise of IBD biosimilars and what comes next

Biosimilars present untapped potential for expanding patient access and improving treatment options in Inflammatory Bowel Disease (IBD) and other therapeutic areas, but these trials also bring unique challenges and regulatory considerations.

In this white paper, you’ll learn how biosimilars have transformed the treatment landscape for IBD in the past decade, their current therapeutic uses in Crohn’s disease and ulcerative colitis, and global regulatory considerations for running biosimilar clinical trials in IBD.

  • IBD epidemiology and current biosimilar treatment methods
  • Regulatory considerations and other challenges for biosimilar trials
  • Future opportunities for biosimilar therapeutics

Inflammatory Bowel Disease: Current Status and Future Perspectives

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.

NSCLC Clinical Trials: History, Trends, and Opportunities

Lung cancer is one of the diseases that will never vanish from the radar of physicians, scientists, and society. However, there have been significant advances in our understanding and treatment of this disease over the past century, particularly for non-small cell lung cancer (NSCLC). In this white paper, we review the primary diagnostic and treatment options used today, the current trends, and their implications on the design and conduct of NSCLC clinical trials.

Based on PSI CRO’s experience with more than 25 Phase 2 and 3 clinical trials in advanced and metastatic NSCLC during the past ten years, we have experience overcoming several major challenges of these studies. To learn more about how we can support your upcoming NSCLC clinical trial, contact us today.

A Guide to the EU Clinical Trial Regulation: How to Ensure Timely Transition for Current Studies

With the European Union’s Clinical Trial Regulation coming into effect on January 31, 2022, we know there are many questions when it comes to what’s changing and what you need to do to comply. That’s why PSI CRO, drawing on our 25 years of experience managing studies across the globe, is sharing our insights in a new white paper.

In A Guide to the EU Clinical Trial Regulation: How to Ensure Timely Transition for Current Studies, you’ll learn:

  • The new elements introduced by the EU CTR
  • The applicability for current studies
  • How to transition your study to the new requirements
