What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of this clinical trial is to learn about the effects of fluconazole in patients who plan to start or are currently undergoing standard of care treatment and plan to dose-escalate an IL-23 therapy for their Crohn's disease. The main question it aims to assess is whether or not patient response to IL-23 therapies improve when simultaneously treated with fluconazole.

Will I have to stop taking my current medications?

The trial requires that you stay on a stable dose of your current medications for at least 4 weeks before starting the treatment. However, you cannot participate if you are taking medications that interact with fluconazole and cause serious side effects.

Is IL-23 therapy safe for treating Crohn's disease?

IL-23 therapy, including drugs like risankizumab, has shown a favorable safety profile in treating Crohn's disease and other inflammatory conditions, with studies indicating it is generally safe for human use. ^{1 2 3 4 5}

How is the Fluconazole + IL-23 therapy different from other Crohn's disease treatments?

The Fluconazole + IL-23 therapy is unique because it combines an antifungal medication, Fluconazole, with a focus on blocking IL-23, a protein involved in the immune response that contributes to Crohn's disease. This approach is different from traditional treatments that often target broader immune pathways, as it specifically aims to inhibit the IL-23 pathway, which has shown promise in treating other immune-related conditions. ^{2 3 4 6 7}

What data supports the effectiveness of the drug Fluconazole + IL-23 Therapy for Crohn's Disease?

Research shows that targeting IL-23, a part of the immune system, is effective for treating Crohn's disease. Drugs like risankizumab, which block IL-23, have shown promising results in clinical trials for Crohn's disease, suggesting that therapies targeting IL-23 can be beneficial. ^{2 3 4 6 8}

What Are the Treatments Tested in This Trial?

Interventions

• Fluconazole

Trial Overview The trial is testing whether taking an anti-fungal medication called fluconazole alongside standard IL-23 therapy improves outcomes in Crohn's disease compared to a placebo (a pill without active medicine).

How Is the Trial Designed?

Group I: IL-23 Therapy with Fluconazole Experimental Treatment 2 Interventions

Fluconazole will be blindly administered as capsules for oral consumption. On the first day, 200 mg will be given. Subjects will then take 100 mg once daily for thirteen days.

Group II: IL-23 Therapy with Placebo Placebo Group 2 Interventions

Placebo will be blindly administered as capsules for oral consumption. On the first day, 200 mg will be given. Subjects will then take 100 mg once daily for thirteen days.

Published Research Related to This Trial

Targeting interleukin-23 (IL-23) significantly improves clinical and endoscopic remission rates in patients with moderate-to-severe Crohn's disease, based on a systematic review of 18 trials involving 5561 participants.

The use of IL-23 inhibitors is associated with a lower risk of serious adverse events compared to placebo, indicating that these treatments are both effective and safe for patients.

Efficacy and Safety of IL-12/23 and IL-23 Inhibitors for Crohn's Disease: Systematic Review and Meta-Analysis. Vuyyuru, SK., Solitano, V., Hogan, M., et al.[2023]

Ustekinumab, a monoclonal antibody that blocks the common p40 subunit of IL-12 and IL-23, has been effective in treating Crohn's disease (CD) in both patients new to biologics and those who did not respond to TNF antagonists, marking a significant advancement in treatment options.

Newer monoclonal antibodies targeting the specific p19 subunit of IL-23, such as risankizumab and brazikumab, have shown promising results in phase II trials for CD, suggesting they may offer superior efficacy compared to ustekinumab.

Interleukin 23 (IL-23) is crucial in causing inflammation in Crohn's disease and ulcerative colitis, and targeting it could improve treatment outcomes for these conditions.

Four monoclonal antibodies that selectively inhibit IL-23 are currently in advanced clinical trials for inflammatory bowel disease, showing promise as effective therapies.

Targeting the IL-23/Th-17 pathway with specific antagonists, such as risankizumab, has shown promise in treating moderate-to-severe Crohn's disease, with recent approval highlighting its efficacy.

Compared to broader IL-12/23 antagonists like ustekinumab, IL-23p19 antagonists may offer improved clinical outcomes, suggesting a more targeted approach could enhance treatment effectiveness for inflammatory bowel disease.

In a study involving 108 patients with moderately to severely active Crohn's disease, extended intravenous treatment with risankizumab significantly improved clinical remission rates, with 53% of patients achieving remission by week 26 after 12 weeks of treatment.

Risankizumab was well tolerated, with most adverse events being mild or moderate, and it successfully maintained remission in 71% of patients at week 52, indicating its potential as a safe and effective long-term treatment option for Crohn's disease.

Anti-IL-23 agents, such as mirikizumab and ustekinumab, have shown significant efficacy in treating ulcerative colitis (UC) in clinical trials, achieving both clinical and endoscopic improvements with a favorable safety profile.

Ongoing trials are exploring the effectiveness of various anti-IL-23 agents compared to existing treatments and investigating the potential for combination therapies, which could enhance treatment strategies for UC.

In a long-term study of 65 patients with moderate-to-severe Crohn's disease, risankizumab was well tolerated over a median of 33 months, with no new safety concerns and a low rate of serious adverse events (24.6 events/100 patient-years).

Efficacy was maintained throughout the study, with over 71% of patients achieving clinical remission and more than 42% achieving endoscopic remission, indicating that risankizumab remains effective for long-term treatment.

Targeting the IL-23 cytokine pathway, particularly the p19 subunit, shows promise as a safe and effective treatment for Crohn's disease, as indicated by phase I and II clinical trials of monoclonal antibodies like risankizumab and brazikumab.

Both multicenter, randomized, placebo-controlled trials for risankizumab and brazikumab suggest that these IL-23-specific therapies could serve as viable alternatives to existing biologics, with further phase 3 studies needed to confirm their effectiveness in clinical practice.
