What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing guselkumab, a medication that reduces inflammation, in patients with moderate to severe Crohn's disease. It works by blocking a protein called IL-23, which helps to lower inflammation in the body. Guselkumab is a monoclonal antibody that selectively inhibits IL-23 and has shown efficacy in treating inflammatory conditions like psoriasis and Crohn's disease.

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 Guselkumab safe for use in humans?

Guselkumab, also known as Tremfya or CNTO1959, has been evaluated for safety in clinical trials for Crohn's disease and other conditions. The trials showed that it is generally well-tolerated, with most side effects being mild, indicating a good safety profile. ^{1 2 3 4 5}

How does the drug Guselkumab differ from other treatments for Crohn's disease?

Guselkumab is unique because it targets a specific part of the immune system involved in inflammation, which is different from the commonly used treatments for Crohn's disease that often target tumor necrosis factor (TNF). This novel approach may offer an alternative for patients who do not respond well to existing therapies. ^{6 7 8 9 10}

Published Research Related to This Trial

Adalimumab, a fully human monoclonal anti-TNF alpha antibody, has been shown to be clinically effective in treating severe, active Crohn's disease, providing rapid action and maintaining efficacy over 3 years in both treatment-naïve and previously treated patients.

The treatment is associated with a reduction in hospitalization rates and improved quality of life, while its safety profile is comparable to other TNF alpha inhibitors, with low immunogenicity and rare allergic reactions, highlighting the importance of careful patient screening during treatment.

Immunosuppressant and biologic therapies for Crohn's disease and ulcerative colitis can lead to a range of adverse events, from mild symptoms to serious complications like infections and cancers, highlighting the importance of careful monitoring.

The review emphasizes the need for healthcare providers to engage in personalized risk-benefit discussions with patients regarding these therapies, considering individual risk factors to optimize treatment outcomes.

Adverse events in IBD therapy: the 2018 update. Quezada, SM., McLean, LP., Cross, RK.[2019]

Fontolizumab, an anti-interferon gamma antibody, was generally well tolerated in a study of 45 patients with moderate to severe Crohn's disease, with only mild adverse effects reported at higher doses.

While no significant differences in clinical activity were observed between fontolizumab and placebo, the highest dose (4.0 mg/kg) showed a notable reduction in Crohn's disease severity and inflammation markers, suggesting potential biological activity.

In a review of safety data from 3160 patients with Crohn's disease treated with adalimumab over 3401.9 patient-years, serious infections were the most common adverse events, with intraabdominal abscesses being the most frequent.

The standardized mortality rate for patients treated with adalimumab was lower than that reported in a meta-analysis of Crohn's disease patients, indicating a favorable safety profile similar to other TNF antagonists.

A systematic review of 13 clinical trials involving biologic drugs for moderate-severe Crohn's disease showed that most drugs, including upadacitinib and vedolizumab, demonstrated significant efficacy across various health parameters.

All biologic drugs analyzed were well tolerated, with most adverse effects being mild, indicating a good safety profile for patients who do not respond adequately to conventional therapies.

Sulfasalazine and 5-aminosalicylates are the first-line treatments for mild to moderate Crohn's disease, while corticosteroids are used for more severe cases but can lead to steroid dependence and have significant side effects.

Newer treatments, including immunomodulators and biologic agents, are being developed to address steroid resistance and prevent disease recurrence after surgery, expanding the options for managing Crohn's disease effectively.

Immunomodulators and biologics are increasingly used to treat Crohn's disease (CD) to prevent long-term bowel damage, with therapeutic drug monitoring helping to optimize their use.

The rise of new biologic agents and the introduction of biosimilars are important developments in CD treatment, especially given the high costs of biologics and the expiration of patents for some existing treatments.

Antibodies targeting tumor necrosis factor, such as adalimumab, have been shown to effectively induce and maintain remission in patients with ulcerative colitis and Crohn's disease.

A recent randomized controlled trial specifically demonstrated the efficacy of adalimumab in inducing remission in patients with moderately to severely active ulcerative colitis.

A systematic review of 28 studies found that infliximab and adalimumab were more effective than certolizumab pegol and tofacitinib for inducing and maintaining remission in Crohn's disease, highlighting their superior efficacy.

CT-P13 (a biosimilar of infliximab) was shown to be more effective than several biological agents and JAK1 inhibitors for both inducing remission and maintaining steroid-free remission, suggesting it should be recommended for treatment.

Nayar et al. identified specific inflammatory cell populations that play a role in the development of Crohn's disease (CD), highlighting the importance of understanding these cells in disease management.

The study suggests that targeting the gp130-STAT3 signaling pathway could be a promising new treatment strategy for patients with CD who do not respond to anti-TNF antibody therapies, potentially enhancing existing treatment options.
