lasts for more than three months or relapses twice or more within a year.47 HE is one of the most common skin disorders of the hands and in a substantial number of patients, it can develop into a chronic condition.48 CHE affects approximately one in ten adults worldwide.49,50 It is a fluctuating disease characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists.47 The pathophysiology is characterized by skin barrier dysfunction, inflammation of the skin, and alterations of the skin microbiome.49 CHE has been shown to cause psychological and functional burdens that impact patient quality of life,51,52 with approximately 70% of individuals who live with severe CHE admitting to problems in performing everyday activities.53 Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE.54 About Atopic Dermatitis Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by intense itch and eczematous lesions.55 AD is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation.56 Type 2 cytokines, including IL-13, play an important role in the key aspects of AD pathophysiology.55,56 Excessive IL-22 production is also known to contribute to the pathogenesis of AD.57 About Generalized Pustular Psoriasis Generalized pustular psoriasis (GPP) is a chronic, heterogeneous, neutrophilic inflammatory disease associated with skin and systemic symptoms that is distinct from plaque psoriasis. GPP is recognized as a separate clinical entity from other forms of psoriasis, with the IL-36 pathway being a key driver of GPP and triggering response to treatment.58,59 GPP can become life-threatening (mortality rates ranging from 2% to 16%) due to severe complications, such as multisystem organ failure and sepsis requiring urgent hospital care; many GPP patients also suffer from various comorbidities, which contribute to the ongoing burden for the patient and healthcare systems.60,61 GPP symptoms appear unpredictable and present on a continuum, which greatly impacts a patient’s quality of life, and may cause fear and anxiety over the disease course, as well as long-term impacts on quality of life related to work/school, emotional health, social activities, and finances.61,62 About ANZUPGO® (delgocitinib) Cream ANZUPGO® (delgocitinib) cream is currently FDA-approved in the U.S. as the first and only topical pan-JAK treatment for chronic hand eczema (CHE). Use of ANZUPGO in combination with other JAK inhibitors or potent immunosuppressants is not recommended.63 ANZUPGO cream is also approved in the European Union, United Kingdom, Switzerland, United Arab Emirates and Canada under the brand name ANZUPGO for the treatment of moderate-to-severe chronic hand eczema (CHE) in adults for whom topical corticosteroids are inadequate or not advisable. ANZUPGO cream is also under investigation in other markets. ANZUPGO cream is a topical pan-Janus kinase (JAK) inhibitor for the treatment of moderate-to-severe CHE in adults. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE.64 In 2014, LEO Pharma A/S and Japan Tobacco Inc. (JT) entered into a license agreement in which LEO Pharma gained exclusive rights to develop and commercialize delgocitinib for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights. INDICATION AND IMPORTANT SAFETY INFORMATION FOR ANZUPGO® (DELGOCITINIB) CREAM What is ANZUPGO? ANZUPGO is a prescription medicine used on the skin (topical) to treat moderate to severe chronic hand eczema (CHE) in adults who are not well-controlled with or cannot use topical corticosteroids. The use of ANZUPGO along with other JAK inhibitors or strong immunosuppressants is not recommended. IMPORTANT SAFETY INFORMATION ANZUPGO is for use on the skin (topical use) only. Do not use ANZUPGO in or on your eyes, mouth, or vagina. What is the most important information I should know about ANZUPGO? ANZUPGO may cause serious side effects, including: Serious Infections: ANZUPGO may increase your risk of infections. ANZUPGO contains delgocitinib. Delgocitinib belongs to a class of medicines called Janus kinase (JAK) inhibitors. JAK inhibitors are medicines that affect your immune system. JAK inhibitors can lower the ability of your immune system to fight infections. Some people have had serious infections while taking JAK inhibitors by mouth or applying on the skin, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have been hospitalized or died from these infections. ANZUPGO should not be used in people with an active, serious infection. You should not start using ANZUPGO if you have any kind of infection unless your healthcare provider tells you it is okay. You may be at a higher risk of developing shingles (herpes zoster) or eczema herpeticum (a blistery, painful skin rash) during treatment with ANZUPGO. Before starting ANZUPGO, tell your healthcare provider if you: are being treated for an infection or have an infection that does not go away or that keeps coming back have TB or have been in close contact with someone with TB have had shingles (herpes zoster) have had hepatitis B or C think you have an infection or have symptoms of an infection such as fever, sweating, or chills; muscle aches; cough or shortness of breath; blood in your phlegm; weight loss; warm, red, or painful skin or sores on your body; diarrhea or stomach pain; burning when you urinate or urinating more often than usual; and/or feeling very tired After starting ANZUPGO, call your healthcare provider right away if you have any symptoms of an infection. ANZUPGO can make you more likely to get infections or make worse any infections that you have. If you get a serious infection, your healthcare provider may stop your treatment with ANZUPGO until your infection is controlled. Non-melanoma skin cancer. ANZUPGO may increase your risk of certain non-melanoma skin cancers. Your healthcare provider will regularly check your skin during your treatment with ANZUPGO. Avoid sunlamps and limit the amount of time you spend in the sunlight. Wear protective clothing when you are in the sun, and use a broad-spectrum sunscreen Tell your healthcare provider if you have ever had any type of cancer Potential risks from Janus kinase (JAK) inhibition. It is not known whether using ANZUPGO has the same risks as taking oral or other topical JAK inhibitors. Increased risk of death (all causes) has happened in people who were 50 years of age and older with at least one heart disease (cardiovascular) risk factor who were taking a JAK inhibitor used to treat rheumatoid arthritis (RA) compared to people taking another medicine in a class of medicines called TNF blockers. ANZUPGO is not for use in people with RA. Oral or other topical JAK inhibitors have also caused increased cholesterol. Before using ANZUPGO, tell your healthcare provider about all your medical conditions, including if you: have an infection have recently received or are scheduled to receive a vaccine. People who use ANZUPGO should not receive live vaccines right before starting, during treatment, or right after treatment with ANZUPGO are pregnant or plan to become pregnant. It is not known if ANZUPGO will harm your unborn baby are breastfeeding or plan to breastfeed. It is not known if ANZUPGO passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with ANZUPGO. If you use ANZUPGO while breastfeeding, avoid touching the nipple and surrounding area right away after applying ANZUPGO to your hands and wrists Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. What are the most common side effects of ANZUPGO? application site reactions, including pain, tingling, itching, and redness; bacterial skin infections, including finger cellulitis and nail infections; and low white blood cells These are not all of the possible side effects of ANZUPGO.

About SPEVIGO® (spesolimab) SPEVIGO® (spesolimab) is a humanized, selective antibody that specifically blocks the activation of the IL-36R, a signalling pathway within the immune system shown to be involved in the pathogenesis of several autoinflammatory diseases, including GPP. It is the first targeted therapy for the treatment of GPP and has been evaluated in the largest clinical program specifically for the treatment of patients with GPP.67-69 INDICATION AND IMPORTANT SAFETY INFORMATION FOR SPEVIGO® (SPESOLIMAB) INDICATION SPEVIGO is indicated for the treatment of generalized pustular psoriasis (GPP) in adults and pediatric patients 12 years of age or older and weighing at least 40 kg. CONTRAINDICATIONS SPEVIGO is contraindicated in patients with severe or life-threatening hypersensitivity to spesolimab-sbzo or to any of the excipients in SPEVIGO. Reported hypersensitivity reactions have included drug reaction with eosinophilia and systemic symptoms (DRESS). WARNINGS AND PRECAUTIONS Infections: SPEVIGO may increase the risk of infections. In patients with a chronic infection or a history of recurrent infection, consider the potential risks and expected clinical benefits of treatment prior to prescribing SPEVIGO. Treatment with SPEVIGO is not recommended in patients with any clinically important active infection until the infection resolves or is adequately treated. Instruct patients to seek medical advice if signs or symptoms of clinically important infection occur during or after treatment with SPEVIGO. If a patient develops a clinically important active infection, discontinue SPEVIGO therapy until the infection resolves or is adequately treated. Risk of Tuberculosis: Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with SPEVIGO. Avoid use of SPEVIGO in patients with active TB infection. Consider initiating anti-TB therapy prior to initiating SPEVIGO in patients with latent TB or a history of TB in whom an adequate course of treatment cannot be confirmed. Monitor patients for signs and symptoms of active TB during and after SPEVIGO treatment. Hypersensitivity and Infusion-Related Reactions: SPEVIGO-associated hypersensitivity reactions may include immediate reactions, such as anaphylaxis, and delayed reactions, such as drug reaction with eosinophilia and systemic symptoms (DRESS). Drug reaction with eosinophilia and systemic symptoms (DRESS) has been reported in clinical trials with spesolimab-sbzo in subjects with GPP. If a patient develops signs of anaphylaxis or other serious hypersensitivity, discontinue SPEVIGO immediately and initiate appropriate treatment. If a patient develops mild or moderate hypersensitivity during an intravenous infusion or other infusion-related reactions, stop SPEVIGO infusion and consider appropriate medical therapy (eg, systemic antihistamines and/or corticosteroids). Upon resolution of the reaction, the infusion may be restarted at a slower infusion rate with gradual increase to complete the infusion. Vaccinations: Prior to initiating SPEVIGO for treatment of GPP, complete all age-appropriate vaccinations according to current immunization guidelines. Avoid use of live vaccines in patients during and for at least 16 weeks after treatment with SPEVIGO. No specific studies have been conducted in SPEVIGO-treated patients who have recently received live viral or live bacterial vaccines. ADVERSE REACTIONS Intravenous SPEVIGO for Treatment of GPP Flare (Study Effisayil-1): Most common adverse reactions reported in ≥5% of patients treated with SPEVIGO in the clinical trial were asthenia and fatigue, nausea and vomiting, headache, pruritus and prurigo, infusion site hematoma and bruising, and urinary tract infection (UTI). Specific Adverse Reactions Infections : The most frequent adverse reactions that occurred in subjects treated with intravenous SPEVIGO were infections. During the 1-week placebo-controlled period in Study Effisayil-1, infections were reported in 14% of subjects treated with SPEVIGO compared with 6% of subjects treated with placebo. Serious infection (UTI) was reported in 1 subject (3%) in the SPEVIGO group and no subjects in the placebo group. Infections observed through Week 1 in Study Effisayil-1 in subjects treated with SPEVIGO were mild (29%) to moderate (71%). Drug Reaction With Eosinophilia and Systemic Symptoms (DRESS) : Two cases of DRESS were reported in Study Effisayil-1 in subjects with GPP who were treated with intravenous SPEVIGO. RegiSCAR DRESS validation scoring (with the following categories: “no,” “possible,” “probable,” or “definite” DRESS) was applied to the reported cases. Reported cases were assessed as “no DRESS” and “possible DRESS.” Subcutaneous SPEVIGO for Treatment of GPP When Not Experiencing a Flare (Study Effisayil-2): Regarding the exposure-adjusted incidence rates for subjects on randomized treatment prior to receiving rescue treatment for flare or completing trial without a flare, the rate per 100-patient years for injection site reaction (including erythema, pain, swelling, induration, urticaria, and warmth at the injection site) was 31.6 for the subcutaneous SPEVIGO cohort (600 mg loading dose followed by 300 mg every 4 weeks) vs 12.7 for the placebo cohort. The rate per 100-patient years for UTI was 18 for SPEVIGO vs 0 for placebo. The rate per 100-patient years for pruritus was 8.8 for SPEVIGO vs 0 for placebo. The rate per 100-patient years for arthralgia was 13.3 for SPEVIGO vs 6 for the placebo cohort. There were 3 subjects who discontinued subcutaneous SPEVIGO due to treatment-emergent adverse events of psoriasis compared to no subjects in the placebo cohort who discontinued placebo for any treatment-emergent adverse event. Safety in Study Effisayil-2 After Flare: In Effisayil-2, subjects who experienced a GPP flare and received at least one dose of an open-label single intravenous 900 mg dose of SPEVIGO were treated with open-label subcutaneous SPEVIGO 300 mg. These subjects (n=19) received subcutaneous dosing at every 12 weeks, which could have been increased to every 4 weeks based on GPPPGA total score or pustulation subscore increased by ≥1 from any previous open-label maintenance visit. The reported safety profile of open-label subcutaneous SPEVIGO use after treatment of GPP flare with open-label intravenous SPEVIGO use was consistent with the safety profiles of use of SPEVIGO from Trial Effisayil-1 and randomized controlled data from Trial Effisayil-2. Clinical Development of Spesolimab-sbzo Guillain-Barre Syndrome (GBS): Among approximately 835 subjects exposed to spesolimab-sbzo during clinical development, GBS was reported in 3 subjects who received various doses of spesolimab-sbzo via various methods of administration in clinical trials for unapproved indications. SPECIFIC POPULATIONS Pediatric Use: The safety and effectiveness of SPEVIGO for the treatment of GPP have been established in pediatric patients 12 years of age and older and weighing at least 40 kg. Use of SPEVIGO for this indication is supported by data from a randomized, placebo-controlled study, which included 6 pediatric subjects 14 to 17 years of age with a history of GPP treated with subcutaneous SPEVIGO (Study Effisayil-2), and evidence from an adequate and well-controlled study of intravenous SPEVIGO in adults with GPP (Study Effisayil-1), with additional pharmacokinetic analyses showing similar drug exposure levels in adults and pediatric subjects 12 years of age and older and weighing 40 kg or more. The safety and effectiveness of SPEVIGO in pediatric patients younger than 12 years of age or in pediatric patients weighing less than 40 kg have not been established.
