Delgocitinib (Anzupgo) Receives FDA Approval for Hand Eczema

Anzupgo Cream Earns FDA Approval for Chronic hand Eczema Relief

A new topical treatment, Anzupgo, has received FDA approval, offering a promising solution for adults suffering from moderate to severe chronic hand eczema. The cream, developed by Leo Pharma, aims to provide clearer skin and meaningful relief from the pain and itch associated with this persistent condition.

The FDA’s decision was informed by two extensive Phase 3 clinical trials,DELTA 1 and DELTA 2. These studies collectively involved nearly 1,000 adult participants who applied either Anzupgo or a non-medicinal placebo cream twice daily for a period of 16 weeks.

Results from DELTA 1 showed that 20% of individuals using Anzupgo achieved “clear” or “almost clear” skin, a notable enhancement compared to the 10% who experienced similar results with the placebo. The DELTA 2 trial demonstrated even more pronounced efficacy, with a success rate of 29% for Anzupgo users versus only 7% for the placebo group.

Beyond skin clarity,Anzupgo also demonstrated a significant impact on reducing the debilitating symptoms of itch and pain. By the 16-week mark, nearly half of the Anzupgo users reported a four-point or greater reduction in both their itch and pain scores. This level of symptom alleviation could translate from constant, disruptive discomfort to more manageable or even absent symptoms, potentially enabling individuals to work more comfortably, achieve better sleep, and more effectively carry out daily activities.The improvement in chronic itching is also linked to enhanced concentration, improved rest, and better overall mental health. A four-point drop in itch severity frequently enough signifies a shift from an unbearable sensation to one that is manageable or has disappeared entirely.Safety Profile and Dosage

Anzupgo is available in a 2% formulation, with each gram containing 20 milligrams (mg) of the active ingredient, delgocitinib. The FDA-approved usage guidelines recommend no more than 30 grams (g) over a two-week period, or a maximum of 60 g per month.

In clinical studies, Anzupgo exhibited a safety profile comparable to the placebo. The most frequently reported side effects included application-site reactions such as pain, itching, skin discoloration, or tingling. Mild skin infections,like paronychia or cellulitis,were also observed. Additionally, some participants experienced a decrease in white blood cell count.

Anzupgo belongs to the class of drugs known as JAK inhibitors. while these medications can potentially reduce the immune system’s ability to fight infections, and some oral JAK inhibitors have been associated with serious adverse events, Anzupgo’s topical application means it does not carry a black box warning for potentially serious side effects, unlike its oral counterparts.

Availability and Cost

Leo Pharma, the manufacturer of Anzupgo, anticipates making the cream available in the United States by late September or early October 2025. The company has not yet released specific pricing details for U.S. consumers. The final cost at the pharmacy will be influenced by factors such as insurance coverage, copay tiers, and pharmacy benefit designs. Leo Pharma is planning to offer a savings program for commercially insured patients through the Anzupgo Copay Program and will also establish a patient assistance program.

What is Delgocitinib and how Does it Work?

Delgocitinib, marketed as Anzupgo, represents a importent advancement in the treatment of chronic hand eczema (also known as dyshidrotic eczema). Approved by the FDA,it’s the first oral JAK (Janus kinase) inhibitor specifically indicated for adult patients with moderate-to-severe hand eczema who haven’t responded adequately to topical treatments.

JAK inhibitors work by interfering with the JAK-STAT signaling pathway, which plays a crucial role in inflammation and immune responses. In eczema, this pathway is frequently enough overactive, leading to the characteristic symptoms of itchy, red, and inflamed skin. By blocking JAK enzymes, delgocitinib helps to reduce inflammation and alleviate eczema symptoms. Specifically, delgocitinib targets JAK1 and JAK2.

understanding Hand Eczema: Symptoms and Impact

Chronic hand eczema can be incredibly debilitating, impacting daily life considerably. Symptoms include:

Intense itching

Redness and inflammation

Dry, cracked, and scaly skin

Blisters (particularly with dyshidrotic eczema)

Pain and discomfort

These symptoms can make simple tasks like washing hands, typing, or even holding objects extremely difficult. Traditional treatments ofen involve topical corticosteroids and calcineurin inhibitors,but these aren’t always effective,and long-term use can have side effects. This is where delgocitinib offers a new hope for patients.

Delgocitinib Clinical Trial Results: Efficacy and Safety

The FDA approval of anzupgo is based on robust clinical trial data. Key findings include:

significant Symptom Advancement: Studies demonstrated a statistically significant improvement in hand eczema symptoms compared to placebo. Patients treated with delgocitinib experienced a greater reduction in itch and skin lesions.

Rapid Relief: Many patients reported noticeable symptom relief within weeks of starting treatment.

Safety Profile: clinical trials, including a Phase 1 study assessing safety via photo-testing and patch-testing, indicated that delgocitinib (0.3% and 3% ointment formulations) generally has a mild adverse event (AE) profile with good tolerability.

Long-Term Management: While long-term data is still being collected, initial results suggest delgocitinib can provide sustained symptom control.

Delgocitinib vs. Other JAK Inhibitors: What’s the Difference?

Delgocitinib isn’t the first JAK inhibitor to be approved for dermatological conditions. Tofacitinib, a first-generation JAK inhibitor, inhibits all JAK enzymes (JAK1, JAK2, JAK3, and TYK2), with a preference for JAK1 and JAK3. Delgocitinib, however, exhibits a more selective profile, primarily targeting JAK1 and JAK2. This selectivity may contribute to a potentially more favorable safety profile.

Potential Side Effects and Precautions

Like all medications, delgocitinib can cause side effects. Common side effects reported in clinical trials include:

Upper respiratory tract infections

Herpes simplex virus infections (cold sores)

Increased creatine phosphokinase (CPK) levels (monitored with blood tests)

Important Precautions:

Infections: JAK inhibitors can increase the risk of infections. Patients should be monitored for signs of infection.

Malignancies: There is a potential increased risk of certain cancers with JAK inhibitors.

Cardiovascular Events: Patients with cardiovascular risk factors should be carefully evaluated before starting delgocitinib.

Vaccinations: Live vaccines should be avoided during and after treatment with delgocitinib.

Always discuss your medical history and any existing conditions with your doctor before starting delgocitinib.

Dosage and Administration

Delgocitinib (Anzupgo) is administered orally, typically once daily. The recommended dosage is 20mg,taken as two 10mg capsules.It’s crucial to follow
