What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new ointment, CGB-500, to determine its effectiveness for atopic dermatitis, commonly known as eczema. Researchers aim to discover if CGB-500 can reduce the area and severity of eczema patches and ensure its safety. Participants will apply either the CGB-500 ointment or a placebo daily for 8 weeks, tracking symptoms such as itching. This trial suits individuals who have had eczema for at least a year, with noticeable patches covering 1% to 10% of their skin, and who experience frequent itching. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires participants to stop certain medications before starting. You must stop using moderate to strong CYP3A4 and CYP3A5 inhibitors 4 weeks before, topical JAK inhibitors 2 weeks before, and systemic JAK inhibitors 4 weeks before. Other specific medications and treatments also have required stop times before the trial begins.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that CGB-500, a cream containing tofacitinib, is safe for individuals with atopic dermatitis. Studies indicate that the cream remains primarily in the skin, enhancing its effectiveness on the affected area and reducing the risk of side effects elsewhere in the body. Previous trials did not find any unexpected safety issues, which is reassuring. Overall, CGB-500 has met safety standards in past research, suggesting it is safe for participants. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about CGB-500 ointment for eczema because it introduces tofacitinib, a JAK inhibitor, directly into an ointment form. Unlike traditional treatments like topical corticosteroids or calcineurin inhibitors, tofacitinib works by specifically targeting and blocking certain enzymes involved in the inflammatory process, which may lead to reduced inflammation and itchiness. This trial explores two concentrations, 0.5% and 1% tofacitinib, which could potentially offer more customized and effective treatment options. The ointment form provides a direct application to the affected area, which might enhance its effectiveness and reduce systemic side effects, setting it apart from oral or systemic treatments.

What evidence suggests that CGB-500 might be an effective treatment for atopic dermatitis?

Research has shown that CGB-500 ointment may help treat atopic dermatitis, a common type of eczema. In earlier studies, the ointment significantly reduced itching and improved the skin condition of people with moderate to severe atopic dermatitis. About 59% of patients experienced noticeable skin improvement after using CGB-500. It also met safety standards, as it did not cause major side effects for most people. These results suggest that CGB-500 could effectively manage eczema symptoms.

In this trial, participants will receive either CGB-500 ointment with 0.5% tofacitinib, CGB-500 ointment with 1% tofacitinib, or a vehicle ointment as a placebo comparator. ^{1 3 4 5 6}

Published Research Related to This Trial

A study involving 46 patients with chronic atopic eczema found that a topical cream containing 4% sodium cromoglycate (SCG) significantly improved symptoms after 9 weeks compared to a placebo, particularly in mild to moderate cases.

Despite the improvement, SCG showed limited effectiveness in severe eczema, possibly due to its delayed onset of action and low absorption, with bioavailability ranging from 0.01% to 2.75%, suggesting it may be more suitable for managing mild or moderate eczema over the long term.

Narrowband ultraviolet B (NB-UVB) treatment resulted in a 61% reduction in eczema severity (measured by the SASSAD score) in 29 children, compared to a 6% increase in severity in a control group of 26 children who did not receive treatment.

The benefits of NB-UVB treatment not only improved objective eczema scores but also significantly enhanced quality of life, with effects lasting for at least 6 months post-treatment.

In a study involving 100 patients with eczema/atopic dermatitis, clocortolone pivalate 0.1% cream was found to be significantly more effective than a placebo in all measured outcomes, both objective and subjective.

The treatment was well-tolerated with no adverse reactions reported, indicating a high level of safety and excellent patient acceptance for both the active and placebo creams.

CTGO contains 29 identified compounds and has been shown to significantly improve skin conditions in eczema-affected rats by modulating key inflammatory markers and pathways.

The treatment appears to work primarily through the TLR4/NF-κB signaling pathway, suggesting a specific mechanism of action that could guide future research and development.

In a trial with 42 children suffering from chronic atopic eczema, those treated with a 10% sodium cromoglycate ointment showed significant improvements in skin inflammation and symptoms compared to a placebo, with only 4 withdrawals due to ineffectiveness versus 16 in the placebo group.

No side effects were reported, suggesting that sodium cromoglycate ointment could be a safe alternative to topical steroids for treating atopic eczema in children.

Wenguanmu ointment, a traditional Mongolian medicine, effectively treats eczema in mice by reducing inflammation, pain, and itching, as evidenced by decreased levels of pro-inflammatory cytokines and immunoglobulin E.

The ointment's therapeutic effects are linked to the inhibition of the CKLF-1/NF-κB signaling pathway, suggesting a specific mechanism of action that contributes to its efficacy in alleviating eczema symptoms.

In a phase 3 trial involving 211 patients with moderate-to-severe atopic dermatitis, lebrikizumab (LEB) combined with topical corticosteroids (TCS) significantly improved skin condition, with 41.2% of patients achieving a clear or almost clear skin score compared to 22.1% in the placebo group.

The safety profile of LEB was consistent with previous studies, with most adverse events being mild or moderate, and serious adverse events were similarly low in both the LEB and placebo groups, indicating that LEB is a safe and effective treatment option.

In an open trial with 247 eczema patients, Sicorten topicals showed excellent results, with 90% to 100% effectiveness across different types of dermatitis, including atopic and contact dermatitis.

A double-blind trial with 108 patients indicated that Sicorten's effectiveness was comparable to Betnelan, suggesting that Sicorten is a safe and effective treatment option for various forms of dermatitis.

There is currently limited evidence for effective treatments for chronic nodular prurigo (CNPG), as the systematic review found only three randomized controlled trials and six case studies with more than 15 patients, making it difficult to draw strong conclusions.

Ongoing and upcoming randomized controlled trials on new therapies may provide better treatment options for CNPG patients in the future, as existing therapies have shown heterogeneous results and lack targeted approaches.

In a 12-week study involving 208 children with atopic dermatitis, a 4% sodium cromoglicate (SCG) emulsion significantly reduced the SCORAD score by 28% compared to a 19% reduction in the vehicle group, indicating its efficacy in treating the condition.

The SCG treatment also led to a significant reduction in the use of topical steroids, with 35% less usage in the SCG group, and was well-tolerated, with only 12.5% of subjects reporting discomfort at the application site.
