ABX464 for Ulcerative Colitis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment, ABX464, to determine its effectiveness for people with ulcerative colitis who haven't found success with other treatments. The goal is to see if this medication can lead to remission, meaning a reduction or disappearance of symptoms. Participants will be randomly assigned to take either 25 mg or 50 mg of the medication daily, or a placebo, for eight weeks. The trial seeks individuals with moderate to severe ulcerative colitis who haven't responded well to treatments like steroids or biologics and continue to experience symptoms. Those who have tried other medications but still have active symptoms might find this trial suitable. As a Phase 3 trial, this study represents the final step before FDA approval, offering a chance to participate in a potentially groundbreaking treatment.
Will I have to stop taking my current medications?
The trial does not specify if you must stop taking your current medications, but it mentions a 'washout period' (time without taking certain medications) before the screening endoscopy. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that ABX464 is likely to be safe for humans?
Research has shown that ABX464 was safe in earlier studies with people who have ulcerative colitis. In one study, ABX464 was well-tolerated for a year, and more than half of the participants experienced significant symptom improvement. Another study found that ABX464 was safe for patients with moderate to severe ulcerative colitis and helped reduce their symptoms. These results suggest that ABX464, at the doses tested, was manageable for participants. However, as with any treatment, individual reactions may vary, so discussing potential risks and benefits with a healthcare provider before joining a trial is important.12345
Why do researchers think this study treatment might be promising for ulcerative colitis?
Unlike the standard treatments for ulcerative colitis, which often include anti-inflammatory drugs, immunosuppressants, or biologics, ABX464 offers a novel approach. This treatment is unique because it targets inflammation by modulating RNA biogenesis, a different mechanism of action that may offer benefits over traditional therapies. Researchers are excited about ABX464 because it has the potential to deliver significant improvements in managing ulcerative colitis symptoms with a convenient oral daily dose. The hope is that this new mechanism not only provides effective symptom control but also offers a safer profile with fewer side effects compared to existing options.
What evidence suggests that ABX464 might be an effective treatment for ulcerative colitis?
Research has shown that ABX464 can help treat moderate to severe ulcerative colitis. In previous studies, many patients experienced a significant reduction in symptoms, with 58.4% achieving clinical remission after 48 weeks of treatment. Participants in this trial will receive either ABX464 at different dosages or a placebo. In the short term, ABX464 has outperformed a placebo in easing symptoms. The treatment is known for its safety and effectiveness over the long term. These findings suggest that ABX464 could be a promising option for people who haven't had success with other treatments.12367
Are You a Good Fit for This Trial?
This trial is for men and women at least 16 years old with moderate to severe ulcerative colitis who haven't responded well or are intolerant to certain therapies like corticosteroids, immunosuppressants, biologics, S1P receptor modulators, or JAK inhibitors. Participants must have a confirmed diagnosis of UC for over 90 days and active disease. They should agree to use effective contraception if applicable.Inclusion Criteria
