UC Treatment Pathway

See where clinical trials fit into your treatment journey

Mild–Moderate: 5-ASAs

First-line treatment for mild to moderate ulcerative colitis

Standard: Mesalazine (oral and/or rectal), sulfasalazine, or olsalazine

Moderate–Severe: Immunosuppressants

When 5-ASAs alone aren't enough to control inflammation

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

Biologic Therapy

For moderate-to-severe UC unresponsive to conventional therapy

Standard: Infliximab, Adalimumab, Golimumab, Vedolizumab, or Ustekinumab

Advanced / JAK Inhibitors

After biologic failure — next-generation oral therapies

Standard: Tofacitinib, Upadacitinib, Ozanimod, or clinical trial

About Ulcerative Colitis

What is Ulcerative Colitis?

A chronic inflammatory bowel disease causing inflammation and ulcers in the colon and rectum. Affects about 120,000 people in the UK. Symptoms include bloody diarrhoea, abdominal pain, and fatigue.

Why Trials Matter

Up to 40% of UC patients don't maintain remission with current treatments. Clinical trials offer access to new biologics, JAK inhibitors, and novel anti-inflammatory approaches before they're widely available.

Acute Severe Colitis

Some patients develop acute severe flares requiring hospital treatment (IV steroids, ciclosporin, or infliximab rescue). Trials specifically targeting acute severe colitis are particularly important.
