Speakers: Prof. Dr med. Khusru Asadullah and Dr Matteo Megna 11:15-12:00 CEST on Thursday the 26th of September in Amtrium 1, Hall 4, RAI Amsterdam Chronic Hand Eczema Breaking the Silent Conversation Speakers: Prof. Swen Malte John, Prof. April Armstrong, Dr Marie-Louise Schuttelaar 13:00-14:00 CEST on Friday the 27 th of September in Room 7.3, RAI Amsterdam. About Chronic Hand Eczema Chronic hand eczema (CHE) is defined as hand eczema (HE) that lasts for more than three months or relapses twice or more within a year. 29,30 CHE is one the most common skin disorder of the hands with a prevalence rate of approximately 4.7%. 31 In a substantial number of patients, HE can develop into a chronic condition. 32 CHE is a fluctuating disorder characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists. 33 CHE has been shown to cause psychological and functional burdens that impact patient quality of life, 34 with approximately 70% of individuals who live with severe CHE admitting to problems in performing everyday activities, and suffering disruption in their daily life due to the condition. 35 Furthermore, careers and earning potential have also been shown to be impacted by the burden of living with CHE. 36 About Atopic Dermatitis Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense itch and eczematous lesions. 37 Atopic dermatitis is the result of skin barrier dysfunction and immune dysregulation, leading to chronic inflammation. 38 Type 2 cytokines, including IL-13, play an important role in the key aspects of atopic dermatitis pathophysiology. 37,38 Excessive IL-22 production is also known to contribute to the pathogenesis of AD. 39 About Psoriasis Psoriasis is a chronic, systemic inflammatory disease that primarily affects the skin in 125 million people worldwide. 40,41 Psoriasis is the result of skin barrier cell proliferation and the activation of cytokines (a family of proteins involved in immune responses) that cause inflammation. 42 About 80% to 90% of patients are affected by plaque psoriasis, the most common clinical form of psoriasis. 43 The symptoms of plaque psoriasis are itchy or painful raised scaly and inflamed plaques. Plaques may appear anywhere on the body, but often appear on the scalp, knees, elbows and torso. 43 About Anzupgo ® (delgocitinib) cream Anzupgo ® (delgocitinib) cream 20 mg/g is a topical pan-Janus kinase (JAK) inhibitor for the treatment of moderate to severe CHE. It inhibits the activation of JAK-STAT signaling, which plays a key role in the pathogenesis of CHE. 44 The pathophysiology is characterized by skin barrier dysfunction, inflammation of the skin, and alterations of the skin microbiome. 45 Anzupgo is currently approved in the European Union for the treatment of moderate to severe chronic hand eczema (CHE) in adults for whom topical corticosteroids are inadequate or inappropriate. 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 cream for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights. About Adtralza ® (tralokinumab) / Adbry ® (tralokinumab-ldrm) Adtralza ® (tralokinumab), which is marketed under the tradename Adbry ® in the U.S., is a high-affinity fully human monoclonal antibody developed to bind to and inhibit the interleukin IL-13 cytokine, which plays a role in the immune and inflammatory processes underlying atopic dermatitis signs and symptoms. 38,46 Adtralza ® specifically binds to the IL-13 cytokine, thereby inhibiting interaction with the IL-13 receptor α1 and α2 subunits (IL-13Rα1 and IL-13Rα2). 47 Adtralza ® is approved for the treatment of moderate to severe AD in adult and adolescent patients 12 years and older in the European Union, Canada, Great Britain, the United Arab Emirates, and South Korea. Adtralza ® is approved for use in adults with moderate to severe AD in the U.S., Switzerland, Saudi Arabia, and Japan. About Kyntheum ® (brodalumab) Kyntheum ® (brodalumab) is a recombinant fully human monoclonal immunoglobulin IgG2 antibody that binds with high affinity to human IL-17RA and blocks the biological activities of the pro-inflammatory cytokines IL-17A, IL-17F, IL-17A/F heterodimer, IL-17C and IL-17E (also known as IL-25), resulting in inhibition of the inflammation and clinical symptoms associated with psoriasis. IL-17RA is a protein expressed on the cell surface and is a required component of receptor complexes utilized by multiple IL-17 family cytokines. IL-17 family cytokine levels have been reported to be increased in psoriasis. IL-17A, IL-17F and IL-17A/F heterodimer have pleiotropic activities including the induction of pro-inflammatory mediators such as IL-6, GROα, and G-CSF from epithelial cells, endothelial cells and fibroblasts that promote tissue inflammation. IL-17C has been shown to induce similar responses as IL-17A and IL-17F in keratinocytes. Blocking IL-17RA inhibits IL-17 cytokine-induced responses resulting in normalization of inflammation in the skin. 48 Kyntheum ® is indicated in the European Union, Great Britain, the United Arab Emirates, and Brazil for the treatment of moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy. About temtokibart Temtokibart (LEO 138559) is an investigational monoclonal antibody that targets the IL-22RA1 receptor subunit, currently in Phase 2 development for the potential treatment of moderate to severe atopic dermatitis. 49 It blocks the IL-22RA1 subunit and thereby inhibits the effects of the IL-22 cytokine, and potentially also to some extent the effects of IL-20 and IL-24. 49 Temtokibart does not bind to the IL-22 cytokine itself. 49 LEO Pharma has obtained a worldwide exclusive license to develop and commercialize temtokibart from argenx.

The Structure and Dry Powder Inhalation PK of AZD4604Recently, AstraZeneca published in JMC, detailing the development of the inhaled JAK1 inhibitor AZD4604. AstraZeneca completed the Phase I clinical trial of AZD4604 in the UK in January of this year, and AZ plans to conduct Phase II clinical trials for asthma in the United States, Argentina, Brazil, Germany, Malaysia, and Thailand in November 2023 (inhalant, powder). The structure and dry powder inhalation PK of AZD4604 are the focus of this study. The treatment for asthma includes: long-term treatment, medication treatment during acute asthma attacks, and treatment for severe asthma.  Long-term treatment consists of: ①The first-choice reliever medication recommended is a low-dose ICS+Formoterol. ②Targeted drugs such as anti-IL-5 mAb, anti-IL-5R mAb, and anti IL-4R mAb are added in the 5th level treatment plan. The controlling drugs section has also increased the recommendation of Mepolizumab granules, which mainly reduce airway eosinophilic granulocyte inflammation and improve airway hyper-reactivity by inhibiting Th2 cell factors (such as IL-4, IL-5, and IL-13). JAK inhalation inhibitor treatment for asthma: Cytokines are key to initiating and maintaining the inflammatory state of the airways in asthma patients and are often found to be overexpressed in patients' airways. If the airway is stimulated by allergens or viruses, epithelial-derived cytokines IL-25, IL-33, and thymic stromal lymphopoietin will drive the release of cytokines IL-4, IL-5, and IL-13 from lymphocytes, mast cells, and innate lymphocytes. Subsequently, they drive a series of downstream events, most notably eosinophil proliferation, IGE triggered hypersensitivity reactions, airway epithelial cell activation, effector cell chemotaxis. Small molecule JAK inhibitors targeting upstream drivers of cytokine signaling provide a promising approach for asthma treatment. Compared with monoclonal antibody treatment of a single cytokine, multiple cytokine pathways can be simultaneously inhibited. The Structure of Representative Inhalable JAK InhibitorsAstraZeneca also mentioned in JMC that the main challenges of the inhalation project are to achieve the retention of compounds in the lungs, reach the free concentration required for the drug to take effect, and minimize systemic exposure as much as possible. The strategies for achieving lung retention include (i) reducing inherent solubility, (ii) limiting dissolution rate, (iii) reducing membrane permeability; (iv) increasing lung tissue affinity. Reducing systemic exposure through high clearance from the body's circulation is an attractive strategy. However, this only applies to situations where no active metabolites are formed. The structures of compounds 2, 3, 4, 8 all contain basic N, which can enhance the compound's affinity for lung tissue and help with lung retention. Whereas the structures of 1, 5, 6, 7 do not contain basic N. Optimization of Structure-Activity Relationship Compound 11, as the optimization starting point for AZ's development of JAK1 inhalation inhibitors, contains pyrazine fractions which have basic nitrogen that can augment the compound's affinity to lung tissues and contribute to pulmonary retention. Such molecules typically possess a higher Vd, or volume of distribution, which inversely impacts the half-life, resulting in prolonged duration of action, and eventually positively impacting the convenience of inhalation dosing intervals for patients. The lipophilicity of the compound may also favorably increase tissue affinity. Additionally, the drug's distribution may occur in acidic subcellular compartments, namely lysosomes, aiding in augmenting the volume of distribution.  AstraZeneca synthesized approximately over 100 analogues of 11, with implementation examples mentioned in patents. The final product is compound 16, which is a relatively balanced candidate compound. Compared to 11, 16 has a key methoxy substitution and a differential fluorine substitution in pyrimidine. The methoxy fraction in 16 can interact with K908 residues, which could explain why 16 (IC50 less than 3 nM) has superior activity compared to 14 (IC50=20 nM). The compound 16 within the JAK1 x-ray structure (PDB code 6GGH)The Caco-2 permeability (without transporter inhibitor) and efflux are moderate, indicating that the compound will penetrate different layers of the lung and the cell membrane, to reach intracellular targets. As expected, the steady-state volume of distribution (Vdss) calculated from rat intravenous administration is high (9-11 L/kg). Overall, these data justify in vivo lung PK analysis. According to the PK data of compounds 11, 12, 13 and 16 administered intratracheally in rats, the data for compound 16 are the most favorable, with its total lung concentration being relatively higher over time. The Area Under the Curve (AUC) also confirms this, with the AUC being significantly higher (5 - 12 fold) compared to compounds 11 - 13. Properties of Compounds 11-16 Previously, Pfizer's scientists had in 2017 summarized the characteristics that inhaled JAK inhibitors need to possess.  (1) Enhanced activity to lower dosing, considering the dosage size limit of typical Dry Powder Inhaler(DPI) devices (<1mg medicine), minimizing the percentage of active ingredients required in the formulation as much as possible.  (2) High selectivity for JAK2 and JAK3 in the JAK family.  (3) Low systemic exposure and high metabolic clearance rates by targeting the drug only to the site of action (without forming effective active metabolites) to maximize the therapeutic index.  (4) Participation in multiple metabolic pathways to minimize the possibility of any drug-drug interactions.  (5) Suitable solid state characteristics, allowing for mixing with lactose, use in dry powder inhaler devices, and the creation of external ointments or creams.  (6) In enzyme analytics (through kinetic experiments) or cell-based analysis (through cell washing experiments), the inhibitory effects on JAK can be maintained long-term, allowing for persistent pharmacologic effects in vivo.  Overall, the JAK1 inhibitor AZD4604 has excellent JAK1 selectivity and inhaled delivery performance. The lead compounds were determined by optimizing oral dosage and JAK1 selectivity. In addition to maximizing activity, AstraZeneca's approach is to enhance pulmonary tissue affinity and drive pulmonary retention by adjusting lipophilicity based on the alkalinity of N-methyl piperazine. Notably, the significant differences in characteristics after the optimized compound is inhaled are subtle and require extensive in-vivo PK studies. AZD4604 is also effective and safe, as it has high local concentrations in the lung, with negligible systemic exposure. AstraZeneca will subsequently use it as a tool compound for studying the functional role of the JAK1 subtype in asthma biology and examined the impact of JAK inhibitors on T-cell activation and naive CD4+ T-cell differentiation into Th1, Th2, and Th17 subgroups.

BOGART, Georgia, Nov. 14, 2022 (GLOBE NEWSWIRE) -- Lanier Biotherapeutics Inc., (“Lanier” or the “Company”), a developer of first-in-class antibodies targeting retina, dermatology, Type 2 inflammatory diseases, and oncology, today announced that the United States Patent and Trademark Office has issued U.S. Patent 11,492,397, entitled “Neutralizing Monoclonal Antibodies to IL-25 and Uses Thereof.” The patent covers compositions and methods related to IL-25 binding molecules, including LNR 125, which Lanier is currently developing as a first-in-class inhibitor of the alarmin IL-25, an upstream epithelial cytokine that mediates Type 2 inflammation and is implicated in different atopic, allergic, fibrotic, viral infection and inflammatory diseases, as well as certain cancers. “This patent covers our novel approach to treating Type 2 inflammatory disease and is a key addition to our growing intellectual property estate,” said Daniel White, President and CEO of Lanier. “Because many currently available treatments for Type 2 inflammatory disease target particular downstream cytokines, they miss the opportunity to target other mediators. IL-25 binding molecules, including LNR 125, target upstream cytokines called the Alarmins, the very first inflammatory trigger, which enables an effect on all downstream cytokines simultaneously. We believe that neutralizing the activity of IL-25 can have a profound impact on improving the body’s regenerative processes that have been implicated in some of the world’s most complicated diseases, from tumor immunity to eczema. In the case of asthma, targeting IL-25 with LNR 125 may provide the treatment of asthma exacerbations caused by both allergens and viruses, meaningfully reducing viral load, which we believe cannot be accomplished with currently available therapies.” About Lanier Biotherapeutics Lanier Biotherapeutics was founded to develop first-in-class biologics portfolio for specialty disease, with the ultimate goal of improving the way we survive, age, and live. Lanier targets four major verticals: Multi-functional Retina, Type 2 Inflammation, Dermatology, and Immuno-Oncology. Lanier’s lead developments programs include LNR 653.1, a fully humanized anti-VEGF / IL-17A multifunctional antibody for the treatment of retinal neovascularization diseases and LNR 125.38, a fully humanized anti-IL-25 monoclonal antibody for the treatment of Type 2 Inflammatory diseases and cancer.
