4.9 million people live with inflammatory bowel disease (IBD)1 across the globe and endure a myriad of complex, debilitating symptoms. Despite the availability of advanced therapies, there remains an unmet need for improved treatment. For example, for patients with IBD receiving tumor necrosis factor up to 40% fail to achieve clinical remission, and up to nearly 50% of initial responders lose response after one year.2 As such, scientific innovation is urgently needed to address this significant burden and transform gastroenterology (GI) care.

How Does Inflammatory Bowel Disease (IBD) Impact Patients Beyond Physical Symptoms?

Abdominal pain, diarrhea, rectal bleeding, fatigue, and weight loss are just a few of the hallmark symptoms people living with IBD experience.3 Beyond physical discomfort, the effects of uncontrolled or inadequately controlled disease can extend to a patient’s mental and emotional well-being, encompassing everything from relationships to one’s ability to work.

What is IBD?

It’s one of the most complex and impactful chronic conditions affecting the digestive tract; CD or UC are the most common forms. (3)

Are Current Crohn's Disease and Ulcerative Colitis Treatments Falling Short?

Despite a multitude of currently available treatment options in IBD, many patients fail to respond to therapies or lose response over time, which can lead to a “start and stop” cycle through different therapies in search of sustained control.2 In patients who fail to respond or lose response to therapy, ongoing chronic inflammation can drive disease progression and increase the risk of colorectal cancer.3,6

Additionally, scar tissue buildup (fibrosis) is a long-term effect of IBD, commonly impacting patients with CD and in CD, intestinal complications like fistulae and abscesses may also occur and can require hospitalization and surgery.3,6 In fact, more than 30% of patients with CD will develop health complications from this scarring, including narrowing of the intestine (strictures), that can result in further severity of disease and additional inflammation.7 Fibrotic complications also occur in UC, leading to a range of intestinal symptoms like rectal urgency and incontinence, loose stools, diarrhea, and constipation.

Addressing this “start and stop” cycle and inducing sustained healing drives our commitment to GI research – aimed to better understand the pervasive burden of IBD and explore new ways to address inflammation underlying the spectrum of GI diseases.

In his experience treating patients with GI disorders, Phillip Levine, MD, Head of Gastroenterology Clinical Development, Immunology at Sanofi, sees this impact first-hand.

Unfortunately, many patients with UC and CD are inadequately controlled. And over time, patients living with recurrent disease continue to wait for new treatment options to try to alleviate their symptoms and disease course.

Addressing IBD Unmet Medical Needs: Our Immunoscience Approach to Gastroenterology Research

For decades, we have researched different ways to target the immune system to prevent or treat diseases, including studying novel pathways, cell types, and interactions that make up the immune system. Building on this deep legacy in immunology and our unique approach to immunoscience, we are focused on further understanding the immune pathways that drive disease to inform new treatment approaches for these conditions.

Due to the heterogeneity of IBD, our goal is to identify multiple opportunities that have the potential to address a broad spectrum of patients. Currently, our GI pipeline includes emerging mechanisms of action with the potential to address unmet patient needs.

Deepening our understanding of the unique needs of people with GI conditions is central to achieving this goal and advancing innovative medicines that move beyond a one-size-fits-all approach. We seek insights from key members of the GI community — including patients, patient advocacy groups, caregivers, healthcare providers, and policy makers — to understand their perspectives as we work to develop solutions that can address the real challenges and barriers for patients, their family members, and their healthcare providers. 

We work every day to build a GI community that's as diverse as the patients we serve. Understanding the range of different perspectives is fundamental to developing solutions that will truly improve the lives of people living with GI conditions.

Our Commitment to Gastroenterology Patients

By focusing on education, advocacy and measurable impact from the onset of development, we aim to drive global awareness, bring attention to the unmet needs of those suffering from GI conditions, and ensure these individuals are empowered with the knowledge and support to make informed decisions about their care.

As part of the global community, we are committed to enhancing patient care, striving to support the entire journey, and ensuring that each patient receives the right treatment at the right time.
