Vorinostat + Ustekinumab for Crohn's Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether vorinostat, a histone deacetylase inhibitor, can safely reduce inflammation in people with Crohn's disease, which causes gut inflammation and symptoms like diarrhea and abdominal pain. Participants who respond well to vorinostat may continue treatment and later receive maintenance therapy with ustekinumab to control symptoms long-term. The trial seeks adults whose moderate-to-severe Crohn's disease is not well-managed by current medications. As a Phase 1, Phase 2 trial, this research focuses on understanding how the treatment works in people and measuring its effectiveness in an initial, smaller group.
Will I have to stop taking my current medications?
The trial protocol allows some medications to be continued if they meet specific conditions. For example, certain medications like 5-aminosalicylic acid compounds, corticosteroids, and CD-specific antibiotics can be continued if they have been stable for a specified period before the trial. However, some medications, like anti-TNF and anti-integrin therapies, require a washout period (time without taking the medication) before starting the trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that vorinostat, an HDAC inhibitor, is under study for its safety in treating various conditions, including intestinal inflammation. Some studies suggest that vorinostat might aid in gut healing, potentially benefiting those with inflammatory bowel diseases like Crohn's disease. However, as research for this use remains in early stages, detailed safety information for Crohn's patients is not yet fully available.
In contrast, ustekinumab is already approved for treating Crohn's disease and has a well-established safety record. Long-term studies have demonstrated its safety for people with Crohn's disease. Compared to placebo treatments, it consistently shows positive safety results over several years.
Overall, while vorinostat is still under investigation for safety in Crohn's disease, ustekinumab is already recognized as a safe option for many patients.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for Crohn's Disease because they offer unique mechanisms of action compared to existing options like anti-inflammatory drugs, immunosuppressants, and biologics. Vorinostat, primarily known for its cancer treatment capabilities, operates as a histone deacetylase inhibitor, which could modulate immune responses differently and potentially reduce inflammation more effectively in Crohn's patients. Ustekinumab, already used in Crohn's treatment, targets specific proteins involved in inflammation, but in this trial, it's being tested in combination with Vorinostat to explore enhanced effects. This dual approach could offer more robust relief by simultaneously addressing multiple pathways involved in the disease.
What evidence suggests that this trial's treatments could be effective for Crohn's disease?
Research suggests that vorinostat, one of the treatments in this trial, might help reduce inflammation in people with Crohn's disease by blocking certain proteins involved in causing inflammation. Studies have shown that these medications can have strong anti-inflammatory effects in various conditions, including experimental colitis, a model for bowel inflammation.
Ustekinumab, another treatment option in this trial, is already approved for Crohn's disease. It has proven effective, with more than half of patients continuing treatment after two years. Many patients experience symptom relief within a year of starting ustekinumab, and it remains effective over time.678910Who Is on the Research Team?
