RO7790121 for Ulcerative Colitis
(Ametrine-1 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called Afimkibart (also known as RO7790121) for people with ulcerative colitis (UC), a condition that causes inflammation and sores in the colon. The researchers aim to determine if Afimkibart reduces symptoms more effectively than a placebo, which contains no active medicine. Participants will have moderately to severely active UC and will have tried other UC treatments without success. The trial includes two groups: one receiving Afimkibart and the other a placebo, both administered through IV and then injection. For those with long-standing UC who have not responded well to other treatments, this trial might be suitable. As a Phase 3 trial, it represents the final step before FDA approval, offering early access to a potentially effective treatment.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. However, it mentions that certain medicines are prohibited, including anti-TL1A therapy, so you may need to discuss your current medications with the trial team.
Is there any evidence suggesting that RO7790121 is likely to be safe for humans?
Research has shown that Afimkibart (RO7790121), a treatment being tested for ulcerative colitis, has generally been well-tolerated. In one study, participants taking different doses of Afimkibart reported side effects such as ulcerative colitis symptoms, low red blood cell count (anemia), tiredness, headache, and fever. However, these side effects were not severe for most participants. Another report found that Afimkibart was safe for 245 adults with moderate to severe ulcerative colitis, indicating that most did not experience serious problems from the treatment. Overall, these findings suggest that Afimkibart is relatively safe for humans based on past research.12345
Why do researchers think this study treatment might be promising for ulcerative colitis?
Researchers are excited about afimkibart for ulcerative colitis because it offers a new approach compared to standard treatments like aminosalicylates, corticosteroids, and biologics. Unlike these existing options, afimkibart is administered both intravenously and subcutaneously, potentially offering more flexible dosing. Moreover, afimkibart operates through a novel mechanism of action, which might provide relief for patients not responding to current therapies. This fresh approach could lead to better management of symptoms and improved quality of life for those with ulcerative colitis.
What evidence suggests that RO7790121 might be an effective treatment for ulcerative colitis?
This trial will compare afimkibart with a placebo for treating moderate to severe ulcerative colitis (UC). Research has shown that afimkibart, a type of antibody, may help treat UC. Previous studies found that afimkibart can reduce symptoms in patients. In one study, different doses were tested, and afimkibart effectively managed UC symptoms. Patients experienced improvement in their condition with afimkibart treatment. These findings suggest that afimkibart could be a helpful option for people with UC seeking new treatments.12356
