What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether vedolizumab, administered through an IV, can reduce symptoms in people with collagenous gastritis (CG), a condition causing stomach issues like pain and nausea. The study aims to determine the treatment's effectiveness and safety for those with CG. Participants will receive the medication at regular intervals and undergo tests, including surveys and endoscopies (a procedure using a tube to examine the stomach). Suitable candidates for this trial have a confirmed diagnosis of collagenous gastritis and experience symptoms such as abdominal pain or bloating. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that vedolizumab is likely to be safe for humans?

Research has shown that vedolizumab has been tested in many people for various health issues. In studies with adults who have ulcerative colitis or Crohn's disease, vedolizumab was generally well-tolerated. About 6% of patients experienced serious side effects, while 4% faced very serious effects.

Some people have used vedolizumab safely for up to seven years, though there might be a slightly higher risk of gut infections. Overall, past research indicates that the treatment appears safe. However, like any medication, it may have risks. Always consult a healthcare provider to understand what this means for individual circumstances. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for gastritis?

Unlike the standard treatments for gastritis, which often include proton pump inhibitors and H2 blockers to reduce stomach acid, vedolizumab takes a different approach. It is a monoclonal antibody that targets the gut-specific integrin α4β7, which can help reduce inflammation by preventing white blood cells from entering the gut lining. This unique mechanism of action is particularly exciting because it offers a targeted way to address inflammation without affecting the entire immune system. Researchers are hopeful that vedolizumab could provide a more effective and potentially longer-lasting relief for patients with gastritis.

What evidence suggests that vedolizumab might be an effective treatment for collagenous gastritis?

Research has shown that vedolizumab can help treat inflammatory bowel diseases like ulcerative colitis. In one study, about 42% of patients experienced no symptoms after a year of treatment. Another study found that vedolizumab healed the gut lining in 40.6% of patients after one year. These results suggest that vedolizumab, which participants in this trial will receive, might also effectively treat collagenous gastritis, a condition characterized by inflammation of the stomach lining. The treatment targets specific cells in the gut to reduce inflammation and symptoms. ^{6 7 8 9 10}

Published Research Related to This Trial

In a study of 372 patients with chronic antral gastritis, diffuse gastritis, and ulcer disease, the addition of immunomodulators tactivin and levamisol to standard treatment led to faster healing of lesions, with an average healing time of 18.4 days compared to 24.3 days for standard treatment alone.

The use of levamisol not only improved healing times but also reduced the number of recurrences in patients with chronic gastritis and ulcer disease, suggesting it enhances the overall efficacy of treatment.

DA-9601 demonstrated significantly higher endoscopic cure rates for erosive gastritis compared to cetraxate, with cure rates of 56% and 58% for DA-9601 (180 mg and 360 mg) versus 36% for cetraxate in the per protocol analysis.

Both DA-9601 and cetraxate were found to be safe, with no treatment-associated adverse events reported during the 2-week study involving 512 patients.

In patients treated with vedolizumab, the incidence of opportunistic infections was low, at 0.7 per 100 patient-years in clinical trials and 1.0 in long-term safety studies, indicating a favorable safety profile for this medication.

No cases of serious infections like progressive multifocal leukoencephalopathy or hepatitis B/C viral reactivation were reported, and most patients continued treatment without significant issues, suggesting vedolizumab is a safe option for managing inflammatory bowel disease.

Vedolizumab, a gut-selective integrin blocker for Crohn's disease and ulcerative colitis, showed a similar rate of serious adverse events (35.9%) compared to anti-TNF drugs (32.1%) in a study analyzing 499 reports for vedolizumab and 119,620 for anti-TNFs.

The study identified 22 groups of adverse events associated with vedolizumab, including 9 with serious outcomes, suggesting potential cardiovascular risks; however, these findings are preliminary and require further investigation through long-term studies.

In phase III clinical trials, vedolizumab significantly improved clinical response and remission rates in patients with ulcerative colitis compared to placebo at both 6 and 52 weeks, demonstrating its efficacy for this condition.

While vedolizumab showed mixed results for Crohn's disease, it was effective in achieving clinical remission at 52 weeks in maintenance treatment, and it is generally well tolerated, with a lower risk of serious side effects compared to other treatments.

In a study of 2507 patients, vonoprazan combined with antibiotics showed a significantly higher success rate for primary eradication of Helicobacter pylori compared to the traditional proton pump inhibitor (PPI) regimen, especially in patients with chronic gastritis.

The eradication rates for secondary treatment were similar between the vonoprazan and PPI groups, suggesting that while vonoprazan is effective for initial treatment, it may not offer additional benefits for patients who have previously failed treatment.

In a study of 147 treatment-naïve patients with Helicobacter pylori, the eradication rate of vonoprazan-based triple therapy (V-AC) in those with clarithromycin-susceptible infections was found to be 87.3%, which is below the ideal target of 90%.

The V-AC regimen was effective in eradicating 82.9% of clarithromycin-resistant infections, suggesting that with adjustments in dosage or treatment duration, V-AC could be a promising option for resistant cases.

Vedolizumab is a monoclonal antibody that effectively targets the α4β7 integrin to inhibit gut lymphocyte trafficking, providing a safe treatment option for patients with moderate to severe Crohn's disease and ulcerative colitis.

Unlike anti-TNF agents, which some patients may become intolerant to or lose response over time, vedolizumab offers a promising alternative for those who are primary nonresponders or have developed antidrug antibodies.
