Guselkumab for Crohn's Disease
(GRAVITI Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines the effectiveness and safety of guselkumab for people with Crohn's disease, a condition that inflames the digestive tract. Participants will receive injections of either guselkumab or a placebo. The trial seeks individuals who have had Crohn's disease for at least three months and have not found success with other treatments. As a Phase 3 trial, this study represents the final step before FDA approval, giving participants the opportunity to contribute to the potential availability of a new treatment option.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it mentions that you should not have unstable doses of your current Crohn's disease therapy. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that guselkumab, also known as TREMFYA®, is generally well-tolerated by people with Crohn's disease. Studies have found that many patients experienced significant improvement in their symptoms after receiving guselkumab, reaching clinical remission.
Regarding safety, some patients reported side effects such as diarrhea, tiredness, skin rash, and mild infections. However, not everyone experienced these side effects, and they were usually manageable. Importantly, long-term studies have shown good results, suggesting that the treatment is safe for many patients over time.
Overall, while some possible side effects exist, evidence indicates that guselkumab is safe for treating Crohn's disease.12345Why do researchers think this study treatment might be promising for Crohn's disease?
Guselkumab is unique because it targets the protein interleukin-23 (IL-23), which plays a key role in the inflammation process associated with Crohn's disease. Unlike other treatments that may target tumor necrosis factor (TNF) or use broader immunosuppressive strategies, guselkumab's specific focus on IL-23 could potentially offer more precise control of inflammation with fewer side effects. Researchers are excited about guselkumab because its novel approach might bring relief to patients who haven't responded well to existing therapies. Additionally, the subcutaneous injection method provides a convenient and less invasive option for patients.
What evidence suggests that guselkumab might be an effective treatment for Crohn's disease?
Research has shown that guselkumab may help treat Crohn's disease. In one study, about 56.1% of patients taking guselkumab experienced symptom relief after 12 weeks, compared to only 21.4% of those taking a placebo (a non-active treatment). Another study found that 42% of patients had both symptom relief and improved gut health after one year. Long-term results proved even more promising, with over 85% of patients maintaining symptom control after nearly two years. These findings suggest that guselkumab could effectively manage Crohn's disease. Participants in this trial will receive either guselkumab or a placebo to further evaluate its effectiveness.12345
