AI Technical Summary
Existing treatment options are not effective in targeting IL-18-related diseases such as Still's disease, atopic dermatitis, ulcerative colitis, Crohn's disease, and eosinophilic esophagitis, especially because IL-18 levels are too high to be regulated by IL-18-binding proteins, leading to an overdose of free IL-18. Current treatments require frequent administration and may produce adverse reactions.
The drug is administered subcutaneously at a low dose every 4 weeks. It binds to free IL-18 and blocks its pro-inflammatory signaling to achieve a long-lasting therapeutic effect.
This invention enables a low-dose subcutaneous administration regimen of anti-IL-18 antibodies, reducing the frequency of administration, lowering the risk of adverse reactions, and improving the long-term efficacy and safety of treatment. It is applicable to a variety of IL-18-related diseases.

Abstract
Description
Technical Field
[0001] This invention relates to interleukin-18 (IL-18) antibody therapy, and more particularly to low-dose formulations of anti-IL-18 neutralizing antibodies, and the use of such formulations for treating IL-18-related diseases via subcutaneous administration. The invention further relates to the use of such low-dose formulations of anti-IL-18 neutralizing antibodies in the treatment of: Still's disease, such as adult-onset Still's disease (AOSD) or a juvenile-onset form known as systemic-onset juvenile idiopathic arthritis (SoJIA); atopic eczema or atopic dermatitis (AD); inflammatory bowel diseases, such as ulcerative colitis (UC) and Crohn's disease (CD); and eosinophilic esophagitis (EoE). Background Technology
[0002] Interleukin-18 (IL-18) is a pro-inflammatory cytokine produced by immune cells that activates the immune system upon detection of pathogens. In healthy individuals, IL-18 levels return to normal once the immune system clears the pathogens. However, in patients with Still's disease (adult-onset Still's disease AOSD and systemic juvenile idiopathic arthritis SoJIA), elevated IL-18 levels are strongly associated with disease activity. In healthy individuals, total serum IL-18 levels are typically between 100 and 400 pg / ml, while in Still's disease patients, this level can rise to over 500,000 pg / ml. Studies by Kudela et al. have shown that IL-18 levels exceeding 1000 pg / ml are associated with disease activity, with an average IL-18 level of 20,000 pg / ml in these patients. A study by Girard et al. of 37 adult Still's disease (AOSD) patients found that 68% of them had higher IL-18 levels than healthy controls. Similarly, a study by Weiss et al. of 29 patients with systemic juvenile idiopathic arthritis (SoJIA) showed that 79% of the patients had IL-18 levels exceeding 1,000 pg / ml. The study suggests that this high level of IL-18 is one of the key factors driving the pathogenesis of the disease.
[0003] Adult-onset Still's disease (AOSD) is an inflammatory disease characterized by daily fever, arthritis, and a transient rash. First described in children by George Still in 1897, similar cases have since been found in adults who present with clinical manifestations similar to those of children with systemic juvenile idiopathic arthritis (SIA) but do not meet the diagnostic criteria for typical rheumatoid arthritis (Bywaters, EG, Ann Rheum Dis. 30(2), 121-133 (1971)). AOSD is a rare disease. A retrospective study in France estimated the annual incidence of AOSD at 0.16 cases per 100,000 people, with a uniform distribution between sexes (Magadur-Joly G, et al., Ann Rheum Dis. 54(7):587 (1995)). It is estimated that there are approximately 3,500 to 7,000 adult-onset Still's disease patients in the United States (Gerfaud-Valentin M, et al., Medicine (Baltimore) 93(2):91 (2014)). The age of onset of the disease exhibits a bimodal distribution, with the first peak occurring between 15 and 25 years of age and the second peak occurring between 36 and 46 years of age (Magadur-Joly G, et al., Ann Rheum Dis. 54(7):587 (1995)). In addition, there have been clinical reports of cases in patients over 70 years of age (Steffe LA & Cooke CL, JAMA 249(15):2062 (1983)).
[0004] Treatment regimens are tailored to disease stage, clinical symptoms, presence of end-organ damage, and the principle of minimizing adverse effects of glucocorticoids. Initial treatment typically involves nonsteroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids. For refractory patients, immunosuppressants, including methotrexate, are used. If the patient does not respond to the above treatments, biologics, including tumor necrosis factor (TNF) antagonists (such as adalimumab), interleukin-1 (IL-1) antagonists (such as anakinin and cananumumab), or interleukin-6 (IL-6) antagonists (such as tocilizumab), may be used empirically. Close monitoring for macrophage activation syndrome (MAS) is essential in clinical practice. Although this treatment strategy provides at least partial efficacy for most patients, some remain refractory or partially refractory (Jamilloux, Y., et al., Therapeutics and Clinical Risk Management (2014)). Therefore, there is an urgent need for new targeted therapies in clinical practice.
[0005] The clinical course of AOSD can be divided into three main patterns: monophasic (or single-cycle), intermittent, and chronic, with each type accounting for approximately one-third of patients (Kontzias, A. & Efthimiou, P., Drugs 68(3):319 (2008); Gerfaud-Valentin M, et al., Medicine (Baltimore) 93(2):91 (2014)). Patients with monophasic or intermittent courses often progress to the chronic arthropathy pattern (Kontzias, A. & Efthimiou, P., Drugs 68(3):319 (2008); Gerfaud-Valentin M, et al., Medicine (Baltimore) 93(2):91 (2014); Fautrel, B., Best Pract. Res. Clin. Rheumatol.22(5):773 (2008)).
[0006] Most patients with active AOSD will experience symptoms such as fever, transient rash, joint pain, and arthritis. The most commonly affected joints include the knee, wrist, ankle, elbow, proximal interphalangeal joints, and shoulder (Elkon, KB, et al., Arthritis Rheum. 25(6):647 (1982)). Many patients also have myalgia (Pouchot, J, et al., Medicine (Baltimore) 70(2):118 (1991)). Many patients also suffer from myalgia (Pouchot, J, et al., Medicine (Baltimore) 70(2):118 (1991)), pharyngitis (Nguyen, KH & Weisman MH, J Rheumatol. 24(3):592 (1997)) and liver disease (Gerfaud-Valentin, M, et al., Autoimmun Rev. Jul;13(7):708-722 (2014)). Fulminant hepatic failure has also been reported in patients with AOSD (Dino, O, et al., J Rheumatol. 23(4):784–785 (1996)). Cardiopulmonary diseases (Gerfaud-Valentin, M, et al., Autoimmun Rev. Jul;13(7):708-722 (2014);Cheema, GS & Quismorio, FP Jr. Curr Opin Pulm Med. 5(5):305 (1999)), lymphadenopathy (Gerfaud-Valentin, M, et al., Autoimmun Rev. Jul;13(7):708-722 (2014)), and splenomegaly (Gerfaud-Valentin, M, et al., Autoimmun Rev. Jul;13(7):708-722 (2014)) may also occur.
[0007] Adult-onset Still's disease can be complicated by macrophage activation syndrome (MAS), also known as hemophagocytic lymphohistiocytosis (HLH), which occurs in 12% to 19% of patients with AOSD (Arlet, JB, et al., Ann RheumDis. 65(12):1596. (2006); Bae, CB, et al., Medicine (Baltimore) 94(4):e451(2015); Hot, A, et al., Medicine (Baltimore) 89(1):37 (2010)). Other hematologic disorders that may be associated with AOSD include microangiopathic hemolytic anemia associated with thrombotic thrombocytopenic purpura hemolytic uremic syndrome (Diamond, JR, G. J Nephrol. 10(5):253 (1997); Perez, MG & Rodwig, FR Jr., South Med J. 96(1):46 (2003); Arlet, JB, et al., Ann RheumDis. 65(12):1596. (2006)). Up to half of AOSD patients may experience abdominal pain (Gerfaud-Valentin, M, et al., Autoimmun Rev. Jul;13(7):708-722 (2014)) as well as symptoms that may be associated with lymphadenitis, aseptic peritonitis or acute pancreatitis (Fautrel, B., Best Pract Res ClinRheumatol. 22(5):773 (2008)).
[0008] A diagnosis of adult-onset Still's disease can be made if a patient meets ≥5 diagnostic criteria, with ≥2 being primary criteria and no exclusion criteria (Jamilloux, Y, et al., Therapeutics and Clinical Risk Management Dec. (2014)). Primary diagnostic criteria include: body temperature >39°C for >2 weeks; arthralgia or arthritis for >2 weeks; typical non-pruritic orange-red rash; white blood cell count >10,000 / mm³; and granulocyte percentage >80% (Jamilloux, Y, et al., Therapeutics and Clinical Risk Management Dec. (2014)). Secondary diagnostic criteria include: sore throat; lymphadenopathy; splenomegaly; abnormal liver function; and negative results for antinuclear camotetzimibe and rheumatoid factor (Jamilloux, Y, et al., Therapeutics and Clinical Risk Management Dec. (2014)). Exclusion criteria include: infectious diseases; malignant tumors; other rheumatic diseases (such as vasculitis) (Jamilloux, Y, et al., Therapeutics and Clinical Risk Management Dec. (2014)).
[0009] Some treatment goals for AOSD include: controlling inflammation-related signs and symptoms (such as fever, rash, morning stiffness, joint pain, and swelling); controlling inflammation-related laboratory indicators; preventing target organ damage, including joint damage and other major organ complications; and minimizing the risk of treatment-related adverse reactions, covering both short-term and long-term adverse reactions of glucocorticoids.
[0010] IL-18 is a pro-inflammatory cytokine that plays a role in both innate and adaptive immune responses. IL-18 levels are significantly elevated in many patients with acute arterial disease (AOSD). Studies have found that IL-18 concentrations in patients with active AOSD can exceed 100,000 pg / ml, and this concentration is correlated with disease severity (Kudela, H, et al., BMC Rheum 3:4 (2019)). Elevated IL-18 levels are more specific to AOSD than in other systemic rheumatic diseases (Kawashima, M, et al., Arthritis Rheum. 44(3):550 (2001); Kudela, H., et al., BMC Rheum 3:4 (2019)). A 12-week study of 23 patients with AOSD showed that about half of the patients achieved moderate efficacy after treatment with tadekinig alfa (an IL-18-binding protein [IL-18 BP]), suggesting that targeting IL-18 may be an effective treatment strategy in AOSD (Gabay, C, et al. Ann Rheum Dis. Jun;77(6):840-847 (2018)).
[0011] Systemic onset juvenile idiopathic arthritis (SoJIA) is similar to AOSD, but differs in its classification criteria (Silva, JR, and Brito, I, Acta Reumatol Port. 45(2):150-151. (2020)). Some argue that SoJIA and AOSD are the same disease, occurring only in different age groups (Silva, JR, and Brito, I, Acta Reumatol Port. 45(2):150-151. (2020)). SoJIA is a subtype of juvenile idiopathic arthritis characterized by more severe extra-articular manifestations (such as fever and rash). See the National Institutes of Health's Center for Genetics and Rare Diseases for information on systemic juvenile idiopathic arthritis (https: / / rarediseases.info.nih.gov / diseases / 10966 / systemic-onset-juvenile-idiopathic-arthritis) (last accessed: December 14, 2021). This subtype accounts for 10-11% of juvenile idiopathic arthritis cases (see above), and the age of onset is usually between 3 and 5 years old (see above).
[0012] Clinical signs include fever, with fluctuating body temperature over 24 hours and a peak exceeding 39°C; fever is often accompanied by a transient rash, manifesting as diffuse erythema or urticaria-like lesions (same source as above). Arthritis is another typical symptom (same source as above). The number of body parts affected by arthritis varies from person to person, but almost always affects both large and small joints symmetrically (same source as above). Some patients may also experience lymphadenopathy and / or hepatosplenomegaly (same source as above). In addition, other symptoms such as pericarditis, pleural effusion, or serous peritonitis with abdominal pain may occur (same source as above). Patients with SoJIA usually have severe inflammatory disease, with significantly elevated serum ferritin levels and decreased percentage of glycosylated ferritin (same source as above). Clinicians often use the "triad" to diagnose this disease: daily fever lasting more than 2 weeks, arthritis, and rash (see Petty, R et al., J. Rheumatol. 31(2) 390-392 (2004). If the patient does not have a rash, the presence of lymphadenopathy, hepatosplenomegaly, or pleural effusion can also be used as a basis for diagnosis.
[0013] Atopic dermatitis (AD) is a chronic inflammatory skin disease. The estimated prevalence of adult atopic dermatitis in North America, Europe, and Japan is approximately 2.1% to 4.9% (Barbarot 2018). The main pathogenesis of atopic dermatitis involves defects in the skin barrier function and abnormal immune regulation, with abnormalities in innate immunity and the Th2 helper T-cell immune response being particularly crucial. Previously, treatment for moderate to severe atopic dermatitis primarily relied on potent corticosteroids and systemic immunosuppressants, which can produce significant adverse side effects (Newsom 2020). Given that moderate to severe atopic dermatitis severely impacts patients' quality of life, the development of targeted and well-tolerated immunomodulators remains of great importance.
[0014] Studies on serum total IL-18 levels in patients with moderate to severe atopic dermatitis (AD) have shown that their levels are significantly higher than those in healthy controls (Trzeciak 2011; Zedan 2015). Using the Scoring for Atopic Dermatitis Severity Scale (SCORAD), researchers found a positive correlation between elevated serum IL-18 levels and disease severity (Trzeciak 2011; Zedan 2015). Notably, IL-18 levels were even more significantly elevated in the diseased skin cells of AD patients, reaching pathogenic levels (Inoue 2011), and these levels were also correlated with disease severity. Furthermore, data from the Mendelian randomization study also confirm that IL-18 plays a pathogenic role in the pathogenesis of atopic dermatitis (McGowan 2019).
[0015] Inflammatory bowel disease (IBD) is a complex and debilitating condition that can be further subdivided into two distinct multifactorial diseases: Crohn's disease (CD) and ulcerative colitis (UC) (Kaser 2010). Although both diseases are characterized by chronic, relapsing pathological inflammation and damage to intestinal epithelial cells, their clinical presentations differ. In Crohn's disease, discontinuous lesions are visible throughout the intestinal tract, and its pathological mechanism is closely related to dysregulation of antimicrobial peptide (AMP) responses (Fellermann 2003). In ulcerative colitis, the core pathological feature is a significant reduction in goblet cells producing mucin and the mucus layer, which is associated with microbiota-induced exacerbation of colonic inflammation and disease progression (McCormick 1990). While several treatment regimens targeting specific pro-inflammatory cytokines have been approved for the treatment of Crohn's disease and ulcerative colitis, a significant proportion of patients remain unresponsive, and clinical needs remain largely unmet.
[0016] In animal models of colitis, studies have shown that IL-18 plays a crucial role in mediating pathological disruption of intestinal barrier integrity (Nowarski 2015). In this model, knocking out the IL-18 gene in intestinal epithelial cells provided mice with protection against colitis and mucosal damage. Conversely, knocking out IL-18-binding protein (IL-18bp), a negative regulator of IL-18, resulted in severe colitis in mice, accompanied by the loss of mature goblet cells, suggesting that unbound IL-18 in its free state has a pathogenic effect.
[0017] In addition to animal model data, researchers have evaluated IL-18 in UC patients (Wiercinska-Drapalo 2005). Studies have shown that serum IL-18 levels are significantly elevated in UC patients, and this level is correlated with disease severity. Furthermore, research has confirmed that mutations in the NLRC4 inflammasome lead to elevated IL-18 levels, thereby increasing the risk of UC (Steiner 2022).
[0018] The role of IL-18 in Crohn's disease has also been studied. Studies have shown that IL-18 expression levels are significantly higher in inflamed intestinal tissue of Crohn's disease patients compared to unaffected intestinal tissue (Pizarro 1999).
[0019] Genetic analysis provides further evidence for the role of IL-18 in IBD. Mendelian randomization is a well-established research method for assessing the role of biomarkers in disease etiology, minimizing confounding factors and excluding reverse causality. Studies using this technique have confirmed that elevated IL-18 levels are associated with increased susceptibility to IBD (Mokry 2019; McGowan 2019).
[0020] Eosinophilic esophagitis (EoE) is a chronic, immune-mediated inflammatory disease of the esophagus, with an annual incidence of approximately 5–10 cases per 100,000 people (Muir and Falk 2021). Clinically, it is characterized by esophageal dysfunction-related symptoms, and histologically by eosinophilic infiltration of the esophageal epithelium. It falls under the category of eosinophilic gastrointestinal diseases, characterized by eosinophilic inflammation of the gastrointestinal tract without secondary etiology (Reed and Dellon 2019).
[0021] Biologically, EoE and atopic dermatitis overlap in their pathogenesis, and IL-18 plays a clearly defined pathogenic role in atopic dermatitis. In fact, atopic constitution is extremely common in EoE patients; studies show that 20% to 80% of adult EoE patients also have any atopic disease (Dellon 2014). The potential role of IL-18 in the pathogenesis of EoE has been further confirmed by several animal experiments. One study showed that inducing IL-18 expression in a mouse model promotes the development of EoE, while mice with the IL-18 gene knocked out are protected from the disease (Dutt 2015). In another independent study, inhibitors of caspase-1 or NLRP3 that prevent the maturation and release of active IL-18 were shown to protect mice from pathogen-induced EoE in a mouse disease model (Yadavalli 2023).
[0022] In EoE patients, studies have shown that IL-18 expression is upregulated in the serum and tissues (Niranjan 2015). Furthermore, research has confirmed that IL-18 is an essential factor for the differentiation, maturation, activation, and transformation of naive eosinophils into pathogenic eosinophils, which are considered driving factors in the pathological progression of the disease (Venkateshaiah 2018).
[0023] The pro-inflammatory effects of IL-18 are regulated by IL-18-binding protein (IL-18BP), which binds to IL-18 with high affinity and inhibits its function. In this way, the pro-inflammatory signaling of IL-18 can be shut down. In the context of Alzheimer's disease (AD), some studies have speculated that excessively high IL-18 levels exceed the regulatory capacity of IL-18BP, leading to an abnormally high concentration of "free IL-18"; and this free IL-18 can initiate pro-inflammatory signaling. Summary of the Invention
[0024] The inventors of this invention have studied an anti-IL-18 antibody called Camoteskimab (formerly known as AVTX-007, CERC-007, AEVI-007, and MEDI2338), which has been described in detail in WO 2012 / 085015. Camoteskimab shares the same binding epitope to IL-18 as IL-18BP, meaning that it targets only the "free IL-18" that mediates disease. The inventors believe that low doses of Camoteskimab can produce a therapeutic effect because the antibody targets only the active pool of "free IL-18".
[0025] Similarly, in Still's disease, excessively high IL-18 levels exceed the regulatory capacity of IL-18BP, leading to the production of large amounts of "free IL-18." This free IL-18 activates pro-inflammatory signaling pathways. Therefore, for a therapeutic drug to be effective, it should target the pathogenic free IL-18, rather than IL-18 bound to IL-18BP or IL-18 bound to its corresponding receptor.
[0026] Most therapeutic antibodies used to treat diseases are typically administered intravenously (IV). However, some therapeutic antibody preparations can also be administered subcutaneously (SC). Compared to conventional intravenous injection, subcutaneous injection offers several advantages, including shorter administration time, reduced patient discomfort, less drug waste, and a potentially lower risk of medication errors due to the fixed dosage. Furthermore, subcutaneous injection is simpler to administer and easier to maintain than intravenous catheterization. A single subcutaneous injection site can be used continuously for 7 days or more, and patients do not experience the burden of an intravenous infusion pump, allowing for greater freedom of movement. More importantly, the risk of systemic infection associated with subcutaneous injection is generally lower than with intravenous injection.
[0027] However, subcutaneous injection is mostly suitable for delivering low-dose drugs (i.e., below 4 mg / kg). Typically, therapeutic antibodies administered subcutaneously are formulated at concentrations of 100-200 mg / ml, with the aim of controlling the total volume of each dose to 1-1.5 ml. These low doses are often associated with reduced antibody efficacy. Therefore, there is an urgent need to develop a low-dose anti-IL-18 antibody formulation for the treatment of IL-18-related diseases, including Still's disease, atopic dermatitis (AD), ulcerative colitis (UC), Crohn's disease (CD), and eosinophilic esophagitis (EoE).
[0028] The inventors constructed a population pharmacokinetic model using plasma concentrations of kamotskimab and pharmacokinetic (PK) data from two completed adult clinical studies (NCT01322594 and NCT04671251). In these clinical studies, the half-life data of kamotskimab supported a dosing regimen every 4 weeks (Q4W). Subsequently, the inventors used this pharmacokinetic model to simulate a low-dose dosing regimen under the Q4-week dosing schedule.
[0029] Surprisingly, the results of PK model simulations showed that low-dose (i.e., <4 mg / kg) camotetzib was suitable for subcutaneous administration.
[0030] Furthermore, the PK model has been used to evaluate IL-18 binding levels at low doses and / or long dosing intervals. Currently approved biologic therapies for atopic dermatitis often require shorter dosing intervals, such as once weekly (Q1W) or once every two weeks (Q2W), to achieve optimal clinical efficacy. In contrast, the inventors simulated a low-dose (maximum 4 mg / kg), Q12W (dosing once every 12 weeks) regimen.
[0031] Surprisingly, these simulation results demonstrate that not only low-dose camotetzib, but also longer and more convenient dosing intervals, can achieve IL-18 blockade, thereby translating into significant clinical efficacy.
[0032] Therefore, in a first aspect of the invention, an anti-IL-18 antibody or an antigen-binding fragment thereof is provided for use in treating, preventing or improving adult-onset Still's disease (AOSD), systemic juvenile idiopathic arthritis (SoJIA), atopic dermatitis (AD), ulcerative colitis (UC), Crohn's disease (CD) and / or eosinophilic esophagitis (EoE) in subjects, wherein the anti-IL-18 antibody or the antigen-binding fragment thereof is administered subcutaneously at a dose of 0.1-4 mg / kg.
[0033] In a second aspect of the invention, a method is provided for treating, preventing, or improving adult-onset Still's disease (AOSD), systemic juvenile idiopathic arthritis (SoJIA), atopic dermatitis (AD), ulcerative colitis (UC), Crohn's disease (CD), and / or eosinophilic esophagitis (EoE), the method comprising subcutaneously administering an anti-IL-18 antibody or an antigen-binding fragment thereof to a subject requiring appropriate treatment at a therapeutically effective dose of 0.1-4 mg / kg.
[0034] The inventors were surprised to find that low doses of anti-IL-18 antibodies or their antigen-binding fragments (typically camotetramatzine) of only 0.1–4 mg / kg were sufficient to bind to free IL-18 in the subject's body (rather than IL-18 bound to its receptor or IL-18BP), and the binding level reached the expected therapeutic potential. For example, Figure 4 One embodiment of an anti-IL-18 antibody or its antigen-binding fragment (e.g., kamotskimab) is shown, illustrating the lowest steady-state plasma concentrations achievable at three exemplary low doses: 0.25 mg / kg, 1 mg / kg, and 2 mg / kg. Experimental results showed that the mean concentrations of the anti-IL-18 antibody or its antigen-binding fragment corresponding to the 0.25 mg / kg, 1 mg / kg, and 2 mg / kg dose groups neutralized 320,000 pg / mL, 1,300,000 pg / mL, and 2,500,000 pg / mL of free IL-18, respectively—a surprising effect. According to literature, levels of free IL-18 in patients with Still's disease (adults or children), atopic dermatitis, ulcerative colitis (UC), Crohn's disease (CD), and eosinophilic esophagitis (EoE) are significantly lower than these neutralizing concentrations. Therefore, these pharmacokinetic simulations suggest that low-dose kamotskimab is surprisingly suitable for subcutaneous administration. This is partly due to the unique binding mechanism of camotetzumab to IL-18, which means that camotetzumab only neutralizes "free IL-18", thereby targeting the active pathogenic pool of IL-18.
[0035] The inventors further estimated IL-18 binding levels at low doses and / or longer dosing intervals using a PK model. The results showed that, using a dosing regimen once every 12 weeks, low doses of 30 mg, 100 mg, and 300 mg of camotetzimiab (equivalent to 0.4 mg / kg, 1.4 mg / kg, and 4 mg / kg, respectively) achieved IL-18 neutralization rates exceeding 90%. In contrast, currently approved biologic therapies for atopic dermatitis often require short dosing intervals, such as once weekly (Q1W) or once every two weeks (Q2W), to achieve optimal clinical efficacy.
[0036] Advantageously, combining low doses of anti-IL-18 antibodies or their antigen-binding fragments at 0.1–4 mg / kg with longer and more convenient dosing intervals can achieve IL-18 blocking effects and translate into tangible clinical efficacy.
[0037] Advantageously, low doses of only 0.1–4 mg / kg can support subcutaneous administration of anti-IL-18 antibodies or their antigen-binding fragments, thereby shortening the administration time, reducing patient discomfort, minimizing drug waste, and reducing the risk of medication errors through fixed-dose administration. Furthermore, subcutaneous administration is simpler to administer and easier to maintain long-term compared to intravenous administration.
[0038] Anti-IL-18 antibodies used for the above-mentioned therapeutic purposes may contain the CDR (complementarity-determining region) sequence or the variable regions of the heavy and light chains of the antibodies disclosed in WO 2012 / 085015. These antibodies include antibody 1, antibody 1_GL, antibody 2, antibody 3, antibody 4, antibody 5, antibody 6, antibody 6_GL, antibody 7, antibody 7_GL, antibody 8_GL, antibody 9, antibody 10, antibody 11, antibody 11_GL, and antibody 12_GL as disclosed in WO 2012 / 085015.
[0039] Advantageously, the anti-IL-18 antibody of the present invention has the same binding epitope to IL-18 as the binding epitope used by the IL-18 binding protein. Therefore, after administration to a patient, the camotetzumab binds only to free IL-18, thereby blocking the sustained transduction of pro-inflammatory signals.
[0040] Therefore, preferably, the anti-IL-18 antibody or its antigen-binding fragment specifically binds to free IL-18, and preferably does not bind to IL-18 that has already bound to its corresponding receptor or IL-18 binding protein.
[0041] Antibody 12_GL, also known as camotetzumab (formerly known as AVTX-007, CERC-007, AEVI-007, and MEDI2338), is detailed in WO 2012 / 085015. Camotetzumab is a fully human IgG1κ monoclonal antibody capable of binding to and neutralizing IL-18. This antibody can inhibit the formation of the IL-18 / Rα / Rβ active complex in vitro and in vivo. Camotetzumab has a high affinity for its target (63 pM), which is 6 times higher than that of natural IL-18 inhibitors (IL-18 binding proteins), while its Fc binding ability is relatively lower, allowing it to exert its anti-inflammatory effect. As a fully human antibody, camotetzumab holds promise for reducing the probability of developing anti-drug antibodies (ADAs). In various in vitro models, this antibody exhibits IL-18 neutralizing and biological activity by attenuating the effects of IL-18, with an IC50 (half-maximal inhibitory concentration) reaching the sub-nanomolar level. It has also been demonstrated effective in a chronic obstructive pulmonary disease model (human rhinovirus-infected human bronchial epithelial cells (HRV) model), specifically by inhibiting the release of interferon-gamma from peripheral blood mononuclear cells exposed to infected cell culture medium. Furthermore, a 13-week intravenous toxicity study of camoteskiyb has been completed, showing no toxic reactions observed at weekly doses up to 100 mg / kg.

[0062] Preferably, the VH domain is paired with the VL domain to form a camotetzii antibody antigen-binding site; however, as described above, either the VH or VL domain alone can also be used to bind the antigen.

[0084] In a fourth aspect of the invention, a method is provided for treating, preventing, or improving adult-onset Still's disease (AOSD), systemic juvenile idiopathic arthritis (SoJIA), atopic dermatitis (AD), ulcerative colitis (UC), Crohn's disease (CD), and / or eosinophilic esophagitis (EoE), the method comprising subcutaneously administering an anti-IL-18 antibody or an antigen-binding fragment thereof to a subject requiring appropriate treatment at a therapeutically effective dose of 0.1-4 mg / kg, said anti-IL-18 antibody or antigen-binding fragment thereof comprising an antigen-binding site of a kamotskiy monoclonal antibody or an antibody molecule, wherein said anti-IL-18 antibody competitively binds to IL-18 with any antibody molecule that meets the following criteria: (i) is capable of binding to IL-18; and (ii) comprises an antibody molecule listed in Table 1, a VH domain and / or a VL domain, a CDR (e.g., HCDR3), and / or a CDR group.
[0085] For example, in some embodiments, the anti-IL-18 antibody or its antigen-binding fragment may compete with antibody molecules that include the following features for binding to IL-18: (i) a VH domain having the sequence of SEQ ID NO:152 and a VL domain having the sequence of SEQ ID NO:157; (ii) a VH domain having up to 15 amino acid substitutions (e.g., 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1) relative to SEQ ID NO:152 and a VL domain having up to 13 amino acid substitutions (e.g., 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1) relative to SEQ ID NO:157; or (iii) a VH domain and a VL domain having at least 90% sequence identity with SEQ ID NO:152 and SEQ ID NO:157, respectively.
[0086] Competition between anti-IL-18 antibodies can be conveniently detected in vitro, for example using enzyme-linked immunosorbent assays (ELISA) and / or biochemical competition assays. For instance, a specific reporter molecule can be labeled onto an anti-IL-18 antibody, allowing detection of the labeled antibody in the presence of one or more other unlabeled anti-IL-18 antibodies, thereby screening for anti-IL-18 antibodies capable of binding to the same or overlapping epitopes. Such methods are well known to those skilled in the art and are described in more detail herein. According to the invention, variants of the variable region amino acid sequence of any of the VH and VL domains specifically disclosed herein can be used.
[0087] As described above, in some embodiments, the VH domain of the anti-IL-18 antibody or its antigen-binding fragment has at least 75%, at least 80%, at least 85%, at least 90%, at least 93%, at least 95%, at least 96%, at least 95%, at least 97%, at least 98%, or at least 99% amino acid sequence identity with the VH domain of any antibody listed herein, the VH domain sequence of which is detailed in Table 1 attached below; and / or the VL domain of the anti-IL-18 antibody or its antigen-binding fragment has at least 75%, at least 80%, at least 85%, at least 90%, at least 93%, at least 95%, at least 96%, at least 95%, at least 97%, at least 98%, or at least 99% amino acid sequence identity with the VL domain of any antibody listed herein, the VL domain sequence of which is detailed in Table 1 attached below.
[0088] In some embodiments, the anti-IL-18 antibody or its antigen-binding fragment comprises a VH domain having a set of VH CDRs having at least 75%, at least 80%, at least 85%, at least 90%, at least 93%, at least 95%, at least 96%, at least 95%, at least 97%, at least 98%, or at least 99% amino acid sequence identity with the VH CDRs of any antibody listed in Table 1 below; and / or comprises a VL domain having a set of light chain VL CDRs having at least 75%, at least 80%, at least 85%, at least 90%, at least 93%, at least 95%, at least 96%, at least 95%, at least 97%, at least 98%, or at least 99% amino acid sequence identity with the VL CDRs of any antibody listed in Table 1 below.
[0089] Algorithms for calculating the percentage of identity between two amino acid sequences are known in the art, including, for example, BLAST [Altschul et al. (1990) J. Mol. Biol. 215: 405-410], FASTA [Pearson and Lipman (1988) PNAS USA 85: 2444-2448] or the Smith-Waterman algorithm [Smith and Waterman (1981) J. Mol Biol. 147: 195-197], for example, with default parameters.
[0090] In some embodiments, the anti-IL-18 antibody or its antigen-binding fragment can inhibit the binding of IL-18 to one or both of the IL-18 receptor (IL-18R, which includes IL-18Rα / IL-18Rβ) and IL-18BP, thereby reducing the activity of IL-18. In some embodiments, the anti-IL-18 antibody or its antigen-binding fragment can bind to an epitope on the IL-18 molecule that completely or partially overlaps with the IL-18BP binding site.
[0091] For example, the anti-IL-18 antibody or its antigen-binding fragment can specifically bind to an epitope of IL-18 containing one or more of the residues of human IL-18, namely Tyr1, Gly3, Leu5, Glu6, Lys8, Met51, Lys53, Asp54, Ser55, Gln56, Pro57, Arg58, Gly59, Met60, Arg104, Ser105, and Pro107, or containing corresponding residues of IL-18 from other species (e.g., primates such as macaques). Anti-IL-18 antibodies or their antigen-binding fragments can bind to IL-18 epitopes containing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, or all 17 residues selected from human IL-18 residues Tyr1, Gly3, Leu5, Glu6, Lys8, Met51, Lys53, Asp54, Ser55, Gln56, Pro57, Arg58, Gly59, Met60, Arg104, Ser105, and Pro107.

[0096] In some implementations, the subject was diagnosed with SoJIA.
[0097] In some embodiments, the subject's serum free IL-18 level or total serum IL-18 level is elevated. In some embodiments, serum IL-18 levels are measured before administration of an anti-IL-18 antibody or its antigen-binding fragment. In some embodiments, serum IL-18 levels are measured after administration of an anti-IL-18 antibody or its antigen-binding fragment. In some embodiments, the measurement of serum IL-18 levels is used as a biomarker of treatment effectiveness. In some embodiments, the subject's serum IL-18 level is elevated compared to the levels in subjects without AOSD or SoJIA, or compared to the levels in a negative control group. In some embodiments, the subject's serum IL-18 level is measured after administration of the anti-IL-18 antibody, kamaitskyimab, and is used as a biomarker of treatment effectiveness. In some embodiments, the measured serum IL-18 level is the free IL-18 level. In some embodiments, the free IL-18 level is calculated. In some embodiments, the measured serum IL-18 level is the total IL-18 level. In some implementations, the subject's serum free IL-18 level is elevated. In some implementations, the subject's serum total IL-18 level is elevated.
[0098] In some embodiments, the anti-IL-18 antibody or its antigen-binding fragment is administered in the form of a pharmaceutically acceptable composition.
[0099] In some embodiments, the administration period for the anti-IL-18 antibody or its antigen-binding fragment is at least 16 weeks.
[0100] In some embodiments, the anti-IL-18 antibody or its antigen-binding fragment is administered once a week, once every two weeks, once every three weeks, once every four weeks, once every five weeks, once every six weeks, once every eight weeks, once every nine weeks, once every ten weeks, once every eleven weeks, or once every twelve weeks.
[0101] Preferably, the anti-IL-18 antibody or its antigen-binding fragment is administered once every 4 weeks.
[0102] However, most preferably, the anti-IL-18 antibody or its antigen-binding fragment is administered once every 12 weeks.
[0103] In some implementation schemes, the subject's fever subsided.
[0104] In some implementations, the subjects' C-reactive protein (CRP) levels are reduced. In some implementations, the subjects' CRP levels are reduced by ≥50% from baseline to week 4. In some implementations, the subjects' CRP levels are reduced by ≥50% from baseline to week 12.
[0105] In some implementations, the subject's serum IL-18 levels are reduced.
[0106] In some implementations, the subjects' serum total IL-18 levels are reduced.
[0107] In some implementations, the subjects' serum free IL-18 levels are reduced.
[0108] In some embodiments, serum IL-18 levels in the subject decrease to undetectable levels approximately 4 weeks after administration of an anti-IL-18 antibody or its antigen-binding fragment. In some embodiments, serum IL-18 levels in the subject decrease to undetectable levels approximately 12 weeks after administration of an anti-IL-18 antibody or its antigen-binding fragment.
[0109] In some embodiments, approximately 4 weeks after administration of an anti-IL-18 antibody or its antigen-binding fragment, the subject's serum total IL-18 level drops to undetectable levels. In some embodiments, approximately 12 weeks after administration of an anti-IL-18 antibody or its antigen-binding fragment, the subject's serum free IL-18 level drops to undetectable levels. In some embodiments, approximately 12 weeks after administration of an anti-IL-18 antibody or its antigen-binding fragment, the subject's serum free IL-18 level drops to undetectable levels.
[0110] Preferably, the anti-IL-18 antibody or its antigen-binding fragment binds to free IL-18 in the subject's body. It should be understood that free IL-18 can also be referred to as unbound IL-18, meaning that it is not bound to the corresponding receptor or IL-18 binding protein (IL-18BP).
[0111] Most currently available detection methods can only detect total IL-18, which includes IL-18 bound to its receptor, IL-18BP. Total IL-18 levels may not accurately reflect the levels of disease-causing IL-18, as the pathogenic IL-18 may be free, unbound IL-18. Therefore, when methods require the detection of free IL-18, it may be desirable to use a method that detects free IL-18 separately. Alternatively, the level of free IL-18 can be calculated based on the concentrations of total IL-18 and total IL-18BP using formulas known in the art.
[0112] The anti-IL-18 antibody or its antigen-binding fragment can be administered in the form of a pharmaceutically acceptable composition. In various embodiments, the composition containing the anti-IL-18 antibody is provided as a formulation that also includes a variety of pharmaceutically acceptable carriers (see, for example, Gennaro, Remington: The Science and Practice of Pharmacy with Facts and Comparisons: Drugfacts Plus, 20th ed. (2003); Anselet et al., Pharmaceutical Dosage Forms and Drug Delivery Systems, 7th ed., Lippencott Williams and Wilkins (2004); Kibbe et al., Handbook of Pharmaceutical Excipients, 3rd ed., Pharmaceutical Press (2000)). Various pharmaceutically acceptable carriers are available, including excipients, adjuvants, and diluents.

[0114] In various embodiments, the composition may also be formulated into sustained-release capsules, for example, using biodegradable or non-biodegradable polymers. One non-limiting exemplary biodegradable formulation comprises a polylactic acid-glycolic acid copolymer. One non-limiting exemplary non-biodegradable formulation comprises a polyglycerol fatty acid ester. Methods for preparing such formulations are already described, for example, in EP 1125 584 A1.
[0115] Also provided are drug packages and kits comprising one or more containers, each container containing one or more doses of the anti-IL-18 antibody, Kamotsky monoclonal antibody. In some embodiments, a unit dosage form is provided, wherein the unit dosage form contains a predetermined amount of a composition comprising an anti-IL-18 antibody or an antigen-binding fragment thereof, and may or may not contain one or more additional pharmaceutical agents. In some embodiments, such a unit dosage form is supplied as a disposable pre-filled syringe. In many embodiments, the composition contained in the unit dosage form may comprise physiological saline, sucrose, etc.; buffer solutions (such as phosphate buffer, etc.); and / or be formulated within a stable and effective pH range. Furthermore, in some embodiments, the composition can be formulated as a lyophilized powder for injection, which can be reconstituted with a suitable solvent (e.g., sterile water for injection) for use. In some embodiments, the composition comprises one or more substances that inhibit protein aggregation, including but not limited to sucrose and arginine. In some embodiments, the compositions of the present invention comprise heparin and / or a proteoglycan.
[0116] Any of the above methods can be implemented using a kit for detecting and / or treating diseases associated with elevated IL-18 levels, including AOSD or SoJIA, atopic dermatitis (AD), ulcerative colitis (UC), Crohn's disease (CD), and / or eosinophilic esophagitis (EoE). The kit may contain an antibody, one or more non-naturally occurring detectable markers or reporter substances, a pharmaceutically acceptable carrier, a physiologically acceptable carrier, instructions for use, a container, a delivery device, a detection substrate, or any combination thereof.

This additional component may include, but is not limited to, reagents, labeling enzymes, their corresponding substrates, radioisotopes, reflective substances, fluorescent substances, coloring substances, buffer solutions, and plate carriers, as well as all the substances described above.
[0123] According to the present invention, an "isolated" or "biopure" molecule refers to a compound that has been separated from its natural environment. Therefore, the terms "isolated" and "biopure" do not necessarily reflect the degree of purification of the compound. The isolated compounds described in this invention can be obtained from natural sources, prepared by laboratory synthesis techniques, or produced via any such chemical synthesis route.
[0124] IL-18, also known as interleukin-18, interferon-γ-inducible factor, or INF-γ-inducible factor, refers to a pro-inflammatory cytokine encoded by the IL-18 gene, belonging to the IL-1 cytokine family. Similar to IL-1β, it is initially synthesized in an inactive precursor form called pro-IL-18, which is activated upon cleavage by caspase-1. Pro-IL-18 is present in healthy cells and is constitutively expressed by monocytes and epithelial cells. IL-18 has the function of stimulating both adaptive and innate immune responses.
[0125] As used herein, "elevated IL-18" refers to a total IL-18 level detected in a subject that is higher than the normal control level. The normal control level can be determined by those skilled in the art based on the specific circumstances. In some cases, the normal control level is an industry standard generally accepted by those skilled in the art, representing the typical IL-18 level or range in individuals without IL-18-related conditions. In other cases, the normal control level is a reference IL-18 level for the same subject at a specific time point, and determining whether a subject has elevated IL-18 requires relying on IL-18 levels measured in samples taken from that subject at a different time point (usually a subsequent time point).
[0126] The terms "free IL-18" or "free (active) IL-18" as used in this article refer to the unbound form of IL-18, which is the active form of IL-18. In the human body, free IL-18 is neutralized (inactivated) by IL-18BP; IL-18BP binds to IL-18 and inhibits the activity of IL-18 by interfering with the interaction between IL-18 and IL-18Rα.
[0127] As used herein, “bound IL-18” or similar terms refer to IL-18 bound to a natural ligand, optionally IL-18Rα or IL-18BP. The amount of free IL-18 can be calculated using known methods, such as those described in Palladino et al. (2012) J. Neuroinflammation 9(206).

In some embodiments, heavy chain CDR1 corresponds to amino acid residues 31-35 of the Kabat; heavy chain CDR2 corresponds to amino acid residues 50-65 of the Kabat; and heavy chain CDR3 corresponds to amino acid residues 95-102 of the Kabat. For example, see Kabat Sequences of Proteins of Immunological Interest (1987 and 1991, NIH, Bethesda, Md.).
[0133] As used herein, the term "light chain" refers to a polypeptide chain containing at least a light chain variable region, which may or may not have a leader sequence. In some embodiments, the light chain contains at least one segment of a light chain constant region. The term "full-length light chain" refers to a polypeptide chain containing both a light chain variable region and a light chain constant region, which may or may not have a leader sequence.

[0138] The term "lead sequence" refers to a sequence of amino acid residues located at the N-terminus of a polypeptide, whose function is to facilitate the secretion of the polypeptide from mammalian cells. Once the polypeptide is transported out of the mammalian cell, the leader sequence can be cleaved, leading to the formation of the mature protein. The leader sequence can be a natural or synthetic sequence, and it can be heterologous or homologous to the protein it is linked to.
[0139] For peptide, polypeptide, or antibody sequences, "percentage of amino acid sequence identity (%)" and "homology" are defined as follows: After aligning a candidate sequence with a target peptide or polypeptide sequence, and introducing vacancies where necessary to maximize the percentage of sequence identity, the percentage of residues in the candidate sequence that are identical to the target sequence's amino acid residues is calculated relative to the total number of residues in the target sequence. Conserved substitutions are not considered in the sequence identity assessment. Alignment to determine the percentage of amino acid sequence identity can be performed using various methods known in the art, such as publicly available computer software like BLAST, BLAST-2, ALIGN, or MEGALIGN™ (DNASTAR) software. Those skilled in the art can determine appropriate parameters for measuring the alignment, including any algorithms required to achieve maximum alignment across the full length of the compared sequences.
[0140] The terms “inhibition” (verb) or “inhibition” (noun) refer to the attenuation or termination of any event (e.g., protein-ligand binding), or the attenuation or termination of any phenotypic trait, or the reduction or cessation of the probability, degree, or occurrence of that trait. “Reduction” or “inhibition” means a decrease, reduction, or cessation of a particular activity, function, and / or content compared to a control group. The effect of inhibition or reduction does not necessarily reach the level of complete blockade. For example, in some embodiments, “reduction” or “inhibition” means an overall reduction of 20% or more in the relevant indicator; in another embodiment, it means an overall reduction of 50% or more in the relevant indicator; and in yet another embodiment, it means an overall reduction of 75%, 85%, 90%, 95%, or more in the relevant indicator.

Individuals requiring treatment include those already suffering from the disease, those susceptible to the disease, and those needing to prevent the disease from developing. For the purposes of this invention, beneficial or anticipated clinical effects include, but are not limited to: symptom relief, reduction in lesion size, stabilization of the condition (i.e., no further deterioration), delayed or slowed disease progression, improvement or reduction of the condition, and disease remission (whether partial or complete remission, whether detectable). "Treatment" can also refer to an extension of life expectancy compared to the expected life expectancy without treatment. Individuals requiring treatment include those already suffering from the disease, those susceptible to the disease, and those needing to prevent the disease from developing.
[0148] The term "effective dose" or "therapeutic effective dose" refers to a dose of medicine that is effective in treating a subject's disease or condition, such as a dose that partially or completely relieves one or more symptoms. In some implementations, the effective dose refers to the dose at which the desired therapeutic or preventative effect is achieved at the required dosage and duration of administration.
[0149] Adult-onset Still's disease (AOSD) can be diagnosed using various methods. Currently, a generally accepted diagnostic method is based on the following classification criteria: At least five of the following criteria must be met: fever >39°C for 1 week or more; joint pain or arthritis for 2 weeks or more; characteristic rash; white blood cell count >10,000 / mm³ with neutrophils >80%; sore throat; recent significant lymphadenopathy; hepatomegaly or splenomegaly; abnormal liver function tests; negative antinuclear antibody (IF) and rheumatoid factor (IgM) tests. Additionally, at least two of the following criteria must be met: fever >39°C for 1 week or more; joint pain or arthritis for 2 weeks or more; characteristic rash; white blood cell count >10,000 / mm³ with polymorphonuclear leukocytes >80%.
[0150] "Systemic onset juvenile idiopathic arthritis" (SoJIA), "systemic juvenile idiopathic arthritis" (SJIA), or "sJIA" refers to a subtype of juvenile idiopathic arthritis characterized by more severe extra-articular manifestations (fever, rash). This subtype accounts for 10-11% of juvenile idiopathic arthritis cases, with an age of onset typically between 3 and 5 years. Clinical symptoms include: fluctuating body temperature over 24 hours, peaking at 39°C or higher, often accompanied by a transient rash, manifesting as diffuse erythema or urticaria-like lesions; another typical symptom is arthritis, with the number of affected joints varying from person to person, but large and small joints are often nearly symmetrically affected. Some patients may also experience lymphadenopathy and / or hepatosplenomegaly; other symptoms such as pericarditis, pleural effusion, or serous peritonitis with abdominal pain may also be present. SoJIA patients typically have severe inflammatory disease, with significantly elevated ferritin levels and a decreased percentage of glycated ferritin. Doctors typically use the “clinical triad” to diagnose this disease: daily fever lasting more than two weeks, arthritis, and a rash. See Petty, R et al., J. Rheumatol. 31(2) 390-392 (2004). A diagnosis can also be made if the patient has adenosis, hepatosplenomegaly, or serous cavity effusion but no rash.
[0151] Atopic dermatitis (AD) is a chronic, persistent inflammatory skin condition that causes inflammation, redness, and irritation of the skin. It is a common condition that typically begins in childhood, but can affect people of any age. Atopic dermatitis causes intense itching, and scratching can further lead to redness, swelling, cracking, oozing of clear fluid, crusting, and scaling. In most cases, the condition involves exacerbation phases, known as flare-ups, followed by periods of improvement or complete resolution, known as remission phases.
[0152] Inflammatory bowel disease (IBD) refers to a group of chronic inflammatory diseases of the gastrointestinal tract with unknown causes, including Crohn's disease (CD), ulcerative colitis (UC), and unclassified inflammatory bowel disease.

The y-axis represents the percentage of remaining free IL-18, and the x-axis represents time in days. The colored lines represent 100 independent simulations, with the solid black line representing the geometric mean. The red horizontal line represents the critical value for kamotskimab to neutralize 90% of IL-18, and the red vertical line represents the endpoint of the dosing interval used in the simulation. Detailed Implementation
[0165] The inventors constructed a population pharmacokinetic (PK) model using plasma concentration data of kamotskimab and PK data from two completed adult clinical trials (NCT01322594 and NCT04671251). The results of these two clinical trials showed that the half-life data of kamotskimab supported a dosing regimen every 4 weeks (Q4W). This PK model was then used to simulate a low-dose dosing regimen every 4 weeks. To evaluate the dosing regimen for atopic dermatitis (AD), the PK model was further used to estimate IL-18 binding levels at low doses under a 12-week dosing regimen (longer dosing interval).
[0166] The simulation results of the PK model are as follows.
[0167] In addition, the inventors attempted to validate the pharmacokinetics of kamotskimab using a low-dose dosing regimen as described below.
[0168] The following examples are used to illustrate some embodiments disclosed in this disclosure and should not be construed as limiting the scope of protection of this disclosure in any way. In the following examples, "Camoteskimab" refers to an anti-IL-18 antibody comprising the following six CDRs: a heavy chain CDR having the amino acid sequence of SEQ ID NO:122; a heavy chain CDR having the amino acid sequence of SEQ ID NO:123; a heavy chain CDR having the amino acid sequence of SEQ ID NO:124; a light chain CDR having the amino acid sequence of SEQ ID NO:126; a light chain CDR having the amino acid sequence of SEQ ID NO:127; and a light chain CDR having the amino acid sequence of SEQ ID NO:128. In some embodiments, Camoteskimab has a heavy chain variable region (VH) and a light chain variable region (VL), wherein the heavy chain variable region has the amino acid sequence of SEQ ID NO:121 and the light chain variable region has the amino acid sequence of SEQ ID NO:125.
[0169] Example 1 - Evaluation of subcutaneous administration of carmotskimumab in population drug trials in adult subjects with onset Still's disease generational dynamics model
[0170] Population pharmacokinetic (PK) models were constructed using plasma concentration data of kamotskimab and PK data from two completed adult clinical trials. The two clinical trials were NCT04671251 (AEVI-007-MM-101, sample size n=13) and NCT01322594 (CD-RI-MEDI2338-1033, sample size n=24). The two-compartment linear clearance model showed the best fit to the data. A goodness-of-fit plot was used for validation to confirm the absence of any systematic bias or trend. The values of pharmacokinetic parameters such as clearance and volume of distribution are consistent with the reported ranges for antibody drugs in the literature. As observed in the aforementioned clinical trials, the half-life data of kamotskimab supports a dosing regimen every 4 weeks (Q4W).
[0171] Subsequently, the PK model was used to simulate three dosage regimens under the Q4W plan: 0.25 mg / kg, 1 mg / kg, and 2 mg / kg. The simulation results are detailed in [link to simulation results]. Figures 1 to 3 The summarized data is as follows Figure 4 As shown.
[0172] Figure 4 The average valley concentration (C) trough The values represent the lowest steady-state plasma levels of kamotisumab achieved at the aforementioned doses. The mean concentrations of kamotisumab corresponding to the dose groups of 0.25 mg / kg, 1 mg / kg, and 2 mg / kg neutralized 320,000 pg / mL, 1,300,000 pg / mL, and 2,500,000 pg / mL of free IL-18, respectively. Existing literature data indicate that the levels of free IL-18 in adult-onset Still's disease or atopic dermatitis are much lower than these values. Therefore, the above PK simulation results confirm that low-dose kamotisumab is unexpectedly suitable for subcutaneous administration.
[0173] Example 2 - Pharmacokinetic evaluation of the ability of low-dose kamotskimab to neutralize free IL-18 in animal serum Dynamics study
[0174] The standard formulation used in the above clinical trials, with a concentration of 50 mg / mL, will be concentrated to 100 mg / mL or higher.
[0175] The aforementioned new high-concentration formulation will be used in subcutaneous PK studies (e.g., in humans (healthy volunteers or patients) or monkeys) to verify that the physicochemical properties and biological activity of the antibody are not affected under low-dose conditions, while confirming that low-dose administration can enable camotetzib to reach serum concentrations sufficient to effectively neutralize IL-18.
[0176] The physicochemical properties of the antibodies to be evaluated include, but are not limited to: the presence or absence of aggregates, the degree of protein degradation (both of which can be detected by HPLC analysis), and / or the molecular weight of antibody subunits, which can be determined by gel electrophoresis. In addition, the viscosity of the high-concentration formulation will be analyzed to ensure that it is suitable for subcutaneous injection.
[0177] Similarly, the antibody biological activities to be evaluated include, but are not limited to, verifying the binding affinity of camotetzigmab to IL-18 (i.e., the antibody titer) through an antigen-binding assay. In addition, a cell-based activity assay will be employed to confirm that camotetzigmab can block the biological function of IL-18 by detecting its ability to induce the production of other cytokines (such as interferon-gamma).
[0178] The pharmacokinetics (PK) of the antibody administered subcutaneously will then be evaluated in animals or humans, with an intravenous (IV) injection group serving as a control. More specifically, experimental animals will be administered different doses of the antibody subcutaneously or intravenously, and blood samples will be collected and analyzed at different time points within a defined time period to determine serum camotetzumab concentrations. This analysis will confirm that subcutaneous injection can achieve serum camotetzumab concentrations required for clinical studies.
[0179] The results from the experimental and control groups will be compared and analyzed to determine the pharmacokinetic (PK) characteristics and antibody clearance rates of subcutaneous and intravenous administration. These data will be used to optimize the PK model and dosage simulation protocol before initiating clinical studies in human patients to test low-dose subcutaneous administration of kamotskimab.
[0180] Example 3 - Evaluation of population pharmacokinetics of subcutaneous administration of kamotskimab in subjects with atopic dermatitis (AD) Learning Model
[0181] Three low-dose dosing regimens were further simulated using the PK model described in Example 1, with doses of 30 mg, 100 mg, and 300 mg (equivalent to 0.4 mg / kg, 1.4 mg / kg, and 4 mg / kg, respectively), administered every 12 weeks (Q12W). This study also included simulations of a high-dose (300 mg) regimen administered every 4 weeks (Q4W). These simulations were used to determine the remaining percentage of free IL-18 after camotetzimiab treatment; the simulation results are detailed in [link to simulation results]. Figure 5 Given that the elevated IL-18 levels in patients with UC, CD, and EoE are similar to those in patients with AD, these PK simulation results are also applicable to studies of subcutaneous administration of low-dose camotetzizumab for the treatment of UC, CD, and EoE.
[0182] Each graph contains 100 independent simulations, with the black solid line representing the average. The data show that all dosages and dosing regimens can achieve a neutralization rate of over 90% for IL-18. This indicates that low-dose camotetzimiab can not only achieve this effect, but also, with longer and more convenient dosing intervals, can achieve IL-18 blockade, thus translating into clinically meaningful efficacy.
[0183] Example 4 - Formulation of an anti-IL-18 antibody drug suitable for subcutaneous delivery
[0184] The inventors prepared a high-concentration formulation of kamotskiy monoclonal antibody at a concentration of 100 mg / mL and subsequently evaluated its properties and suitability for subcutaneous injection using a microinjector. Preliminary results showed that the high-concentration formulation possesses suitable properties for subcutaneous administration and microinjector use. Notably, the pH value of the formulation is within the range that is unlikely to induce adverse reactions such as injection site pain, and the viscosity meets the requirements for use with standard autoinjectors.
