Trial Summary

What is the purpose of this trial?

This trial tests two treatments for adults with severe chronic hand eczema who haven't improved with standard treatments. Participants will use either a special cream or take capsules to see which works better in reducing symptoms and improving quality of life.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications before starting. You must not use systemic immunosuppressive drugs, retinoids, or corticosteroids within 28 days before the trial, and you should not apply certain treatments on your hands within 14 days before the trial.

What data supports the effectiveness of the drug for chronic hand dermatitis?

Research shows that alitretinoin, a vitamin A derivative, is effective in treating severe chronic hand eczema, especially in patients who do not respond to standard topical treatments. Clinical trials and real-world studies have demonstrated that alitretinoin significantly improves the condition, with many patients achieving clear or almost clear skin. ^{1 2 3 4 5}

Is the combination of Delgocitinib Cream and Alitretinoin safe for treating chronic hand dermatitis?

Alitretinoin has been shown to be generally safe for treating chronic hand dermatitis, with most side effects being mild or moderate and reversible. Delgocitinib cream has also been found to be safe, with most side effects being mild and unrelated to the cream. ^{1 2 4 6 7}

How is the drug combination of Delgocitinib Cream and Alitretinoin Capsules unique for treating chronic hand dermatitis?

This treatment combines Delgocitinib, a topical Janus kinase (JAK) inhibitor, with Alitretinoin, an oral retinoid, offering a novel approach by targeting inflammation both topically and systemically. Delgocitinib is the first topical JAK inhibitor approved for skin conditions, while Alitretinoin is the only systemic treatment approved for severe chronic hand eczema unresponsive to topical corticosteroids. ^{2 3 4 8 9}

Findings from Research

In a study of 32 subjects with severe chronic hand eczema unresponsive to topical corticosteroids, alitretinoin was found to be effective, with 62.8% of those taking 30 mg daily achieving clear or almost clear hands after 24 weeks.

Alitretinoin was well tolerated and did not cause drug accumulation or time-dependent changes in exposure, indicating its safety for chronic use in this patient population.

Pharmacokinetics, efficacy and safety of alitretinoin in moderate or severe chronic hand eczema. Schmitt-Hoffmann, AH., Roos, B., Sauer, J., et al.[2018]

A study analyzing adverse drug reactions (ADRs) of alitretinoin over 41 months found 52 serious and 88 non-serious unexpected ADRs, with a notable incidence of psychiatric disorders, including depression and suicidal ideation, making up 23% of serious cases.

Newly identified serious ADRs included myocardial infarction, pancreatitis, and digestive hemorrhage, raising safety concerns, particularly for patients with cardiovascular risk factors, leading to restrictions on alitretinoin prescriptions to dermatologists.

In a 52-week study involving 506 Japanese patients with atopic dermatitis, delgocitinib 0.5% ointment demonstrated long-term efficacy, maintaining improvement in skin condition as measured by the modified Eczema Area and Severity Index (mEASI).

The ointment was well tolerated, with 69% of patients reporting mild adverse events, primarily nasopharyngitis, and no significant skin issues like atrophy or telangiectasia observed at application sites.
