What is this trial about?

A plain-language summary of the goals, design and what participants do

This study focuses on patients with Ulcerative Colitis, a chronic inflammatory condition affecting the large intestine. The research evaluates the long-term safety of filgotinib, which is available as film-coated tablets under the brand name Jyseleca. This medication is taken by mouth and comes in two strengths: 100 mg and 200 mg.

The purpose of this research is to observe how safe filgotinib is when used over an extended period by patients who have previously participated in other studies of this medication for Ulcerative Colitis. The study will monitor various aspects of patient health while they are taking the medication.

During the study, participants will continue receiving filgotinib treatment while researchers track their health through regular check-ups and laboratory tests. The study will also measure how well the medication controls the symptoms of Ulcerative Colitis using a scoring system that evaluates disease activity. The total duration of treatment may extend up to several years to gather comprehensive long-term safety information.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial screening and enrollment

    You will be enrolled after completing a previous study with filgotinib for ulcerative colitis treatment

    You must sign an informed consent form before starting any study procedures

    If you are a woman who can become pregnant, you will need to take a pregnancy test

  2. Step 2

    Medication administration

    You will receive Jyseleca (filgotinib) tablets to take by mouth

    The tablets come in two strengths: 100 mg and 200 mg film-coated tablets

    Your doctor will determine the appropriate dose for you

  3. Step 3

    Regular monitoring

    Your safety will be monitored through regular check-ups

    Laboratory tests will be performed to check your health status

    Your vital signs will be measured during visits

    Your ulcerative colitis symptoms will be evaluated using the Mayo Clinic Score

  4. Step 4

    Ongoing requirements

    If you are a woman who can become pregnant, you will need monthly pregnancy tests

    You must use appropriate birth control methods as specified in the study protocol

    You should not receive live or weakened vaccines during the study and for 12 weeks after the last dose

  5. Step 5

    Study duration

    This is a long-term study that will continue until December 2026

    The purpose is to evaluate the long-term safety of filgotinib in treating ulcerative colitis

Investigated drugs

Filgotinib is a medication used to treat ulcerative colitis, which is a chronic inflammatory condition affecting the large intestine. It works by reducing inflammation in the digestive system by targeting specific proteins involved in the inflammatory process. This medication helps manage symptoms of ulcerative colitis and may help prevent flare-ups of the condition.

What is already known about the treatment

Filgotinib – An oral medication that belongs to the class of Janus kinase (JAK) inhibitors, specifically targeting JAK1, used in the treatment of Ulcerative Colitis (UC). The drug works by blocking specific enzymes involved in inflammation, helping to reduce the symptoms and inflammation associated with UC, a chronic inflammatory bowel disease. Filgotinib is administered as a tablet taken by mouth, and its development represents a newer approach to treating inflammatory conditions through selective immune system modulation. Clinical trials have been conducted to evaluate its long-term safety and effectiveness in patients with UC who have previously received filgotinib treatment.

Investigated diseases

Ulcerative Colitis - A chronic inflammatory bowel disease that affects the large intestine (colon) and rectum. The condition causes inflammation and sores (ulcers) in the digestive tract's innermost lining. The inflammation typically begins in the rectum and extends continuously up into the colon, causing the colon's lining to become red and swollen. People with ulcerative colitis experience recurring periods of active disease followed by periods of remission. The condition can develop gradually or suddenly, and it affects each person differently in terms of severity and extent of colon involvement.
