Crohn's Disease Treatment Pathway

See where clinical trials fit into your treatment journey

Mild–Moderate: First Line

Initial management of mild to moderate Crohn's disease

Standard: Aminosalicylates (5-ASAs), Budesonide, or dietary therapy (exclusive enteral nutrition)

Moderate–Severe: Immunosuppressants

When first-line therapy is insufficient or disease is moderate-to-severe

Standard: Azathioprine, 6-Mercaptopurine, Methotrexate, or systemic corticosteroids

Biologic Therapy

For moderate-to-severe disease unresponsive to conventional therapy

Standard: Anti-TNF (Infliximab, Adalimumab), Vedolizumab, or Ustekinumab

Advanced / Small Molecules

After biologic failure — next-generation oral targeted therapies

Standard: Upadacitinib (JAK inhibitor), Risankizumab, or clinical trial

Refractory / Fistulising

Complex disease including fistulae, strictures, or post-surgical recurrence

Standard: Combination therapy, stem cell therapy (trials), or surgical intervention

About Crohn's Disease

What is Crohn's Disease?

A type of inflammatory bowel disease (IBD) causing chronic inflammation of the digestive tract. Affects about 115,000 people in the UK. Can occur at any age but commonly starts between 15-40.

Why Trials Matter

Up to 50% of Crohn's patients don't achieve lasting remission with current treatments. Research into new biologics, JAK inhibitors, microbiome therapies, and stem cell treatments offers hope for better outcomes.

Fistulising Disease

About 20-40% of Crohn's patients develop fistulae — abnormal connections between organs. These are difficult to treat and clinical trials specifically targeting fistulising disease are particularly valuable.
