Abstract
Description
Background Technology
[0001] Hemophagocytic lymphohistiocytosis (HLH) is a fatal autosomal recessive disorder that manifests in early childhood. This disease is characterized by fever, hepatosplenomegaly, cytopenia, and widespread infiltration of vital organs by activated lymphocytes and macrophages. Macrophage activation syndrome (MAS) (also known as secondary HLH) is a rare but serious and life-threatening condition. MAS is considered to be an excessively inflammatory 'cytokine storm' state associated with rheumatic diseases or other triggers. The exact mechanism of MAS is unclear. However, regardless of the initiating events, the final condition is defined by an overactive immune system leading to chronic inflammation and hemophagocytic activity. MAS is characterized by fever, hyperferritinemia, hemophagocytosis, cytopenia (including pancytopenia), and hepatosplenomegaly.
[0002] Current treatments for HLH / MAS rely on various immunosuppressive regimens, including dexamethasone or other steroids, cyclosporine, and etoposide. These therapies are inherently toxic and increase mortality in pre-existing patients. Therefore, there is a strong need for newer, safer treatments for HLH / MAS patients. Summary of the Invention

[0026] Before describing this disclosure in detail, it should be understood that this disclosure is not limited to the specific compositions or biological systems described, which are of course subject to change. It should also be understood that the terminology used herein is for illustrative purposes only and is not intended to be limiting. As used in this specification and the appended claims, the singular forms “a / an” and “the” include plural references unless the context clearly indicates otherwise. Thus, for example, a reference to “molecule” optionally includes combinations of two or more such molecules, etc.
[0027] As used herein, the term "about" refers to a typical range of error for a corresponding value that is readily known to those skilled in the art. References to "about" values or parameters herein include (and describe) embodiments relating to that value or parameter itself. In cases of doubt or where there is no generally accepted understanding in the art regarding the range of error for a particular value or parameter, "about" means ±1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% of that value or parameter.
[0028] It should be understood that the aspects and embodiments described herein include “comprising aspects and embodiments,” “consisting of aspects and embodiments,” and “substantially consisting of aspects and embodiments.”
[0029] As used herein, the term "antibody" is generally intended to refer to an immunoglobulin molecule comprising four polypeptide chains (two heavy (H) chains and two light (L) chains linked together by disulfide bonds) and its polymers (e.g., IgM); however, immunoglobulin molecules consisting only of heavy chains (i.e., lacking light chains) are also included within the definition of the term "antibody." Each heavy chain contains a heavy chain variable region (abbreviated herein as HCVR or VH) and a heavy chain constant region. The heavy chain constant region contains three domains: CH1, CH2, and CH3. Each light chain contains a light chain variable region (abbreviated herein as LCVR or VL) and a light chain constant region. The light chain constant region contains one domain (CL1). The VH and VL regions can be further subdivided into hypervariable regions called complementarity-determining regions (CDRs), within which are scattered more conserved regions called framework regions (FRs). Each VH and VL consists of three CDRs and four FRs, arranged in the following order from the amino terminus to the carboxyl terminus: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4.
[0030] Unless otherwise specified, as used herein, the term “antibody” should be understood to encompass the complete antibody molecule as well as its antigen-binding fragment. As used herein, the term “antigen-binding portion” or “antigen-binding fragment” (or simply “antibody portion” or “antibody fragment”) of an antibody refers to one or more fragments of an antibody, such as F(ab’)2, F(ab)2, Fab’, Fab, Fv, scFv, etc., that retain the ability to specifically bind to human GM-CSF or its epitopes.
[0031] The term "specific binding" refers to the formation of a relatively stable complex between an antibody or its antigen-binding fragment and the antigen under physiological conditions. Specific binding can occur through at least approximately 1 × 10⁻⁶ cells / units. -8 The characterization is based on a dissociation constant of M or greater. Methods for determining whether two molecules specifically bind are well-known in the art, including, for example, equilibrium dialysis, surface plasmon resonance, etc. However, isolated antibodies that specifically bind human GM-CSF may be cross-reactive with other antigens, such as GM-CSF from other species (orthogonal homologs). In the context of this disclosure, multispecific (e.g., bispecific) antibodies that bind human GM-CSF and one or more other antigens are considered to "specifically bind" human GM-CSF. Furthermore, the isolated antibodies may be substantially free of other cellular material or chemicals.
[0032] The term "pharmaceutical formulation" refers to a preparation that is in a form in which the biological activity of the active ingredient is permitted and that does not contain any other components that would have unacceptable toxicity to a subject administering the formulation. Such formulations are sterile.
[0033] As used herein, the term "treatment" refers to both therapeutic treatment and preventative or preventative measures aimed at preventing or slowing (alleviating) physiological changes or conditions, such as the progression of cancer. Beneficial or desired clinical outcomes include, but are not limited to, relief of symptoms, reduction of disease severity, stabilization (i.e., non-deterioration) of the disease state, delay or slowing of disease progression, improvement or alleviation of the disease state, and mitigation (whether partial or complete), whether detectable or undetectable. "Treatment" can also refer to extended survival compared to expected survival without treatment. Those in need of treatment include those who already have a condition or symptom, those who are susceptible to a condition or symptom, or those whose condition or symptom requires prevention.
[0034] As used herein, the terms “prevention” or “prophylaxis” refer to preventive or protective treatment of a disease or disease state. Prevention of a disease or disease state may include reducing (e.g., alleviating) one or more symptoms of the disease or disease state, for example, relative to a reference level (e.g., symptoms in a similar subject who has not received treatment). Prevention may also include delaying the onset of one or more symptoms of the disease or disease state, for example, relative to a reference level (e.g., the onset of one or more symptoms in a similar subject who has not received treatment). In embodiments, the disease is the one described herein.
[0035] The terms "subject," "individual," "animal," "patient," or "mammal" refer to any subject who requires diagnosis, prognosis, or treatment, particularly mammalian subjects. Mammal subjects include humans, domestic animals, farm animals and zoo animals, racing animals, or pet animals such as dogs, cats, guinea pigs, rabbits, rats, mice, horses, cattle, cows, etc.
[0036] Treatment of macrophage activation syndrome (MAS) or hemophagocytic lymphohistiocytosis (HLH)
[0037] The inventors of this invention tested the anti-GM-CSF antibody IMH001 against macrophage activation syndrome (MAS) or hemophagocytic lymphohistiocytosis (HLH) in animal models. The animals with MAS were immunodeficient and expressed human GM-CSF and IL-3 cytokines. The animals exhibited progressive disease characteristics of many MAS cases, rapidly developing progressive anemia and weight loss.
[0038] Compared to the control group, animals treated with IMH001 showed reduced weight loss (or even weight gain), improved anemia (improved red blood cell count, hemoglobin, and hematocrit), and inhibited ferritin increase. Therefore, these in vivo data demonstrate the efficacy of IMH001 in treating MAS or HLH.
[0039] Therefore, according to one embodiment of the present technology, a method for treating or preventing macrophage activation syndrome (MAS) or hemophagocytic lymphohistiocytosis (HLH) is provided. In some embodiments, the method involves administering an anti-GM-CSF antibody or antigen-binding fragment to a patient in need. As used herein, the term "GM-CSF" refers to human granulocyte-macrophage colony-stimulating factor. GM-CSF, also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, NK cells, endothelial cells, and fibroblasts, which functions as a cytokine. Pharmaceutical analogues of naturally occurring GM-CSF are also known as sargramostim and molgramostim. Antibodies against human GM-CSF are described, for example, in WO 2006122797, WO 2015028657, and WO2018050111.
[0040] In some embodiments, the anti-GM-CSF antibody is IMH001, which is a humanized IgG1 antibody comprising the heavy chain variable region (VH) of SEQ ID NO:1 and the light chain variable region (VL) of SEQ ID NO:2.
[0041] In some embodiments, the patient has MAS or HLH. In some embodiments, the patient is at risk of developing MAS or HLH. In some embodiments, the HLH / MAS patient or the patient at risk of developing HLH / MAS has a disease or condition such as systemic juvenile idiopathic arthritis (SoJIA), systemic lupus erythematosus (SLE), Kawasaki disease, or adult-onset Still's disease.
[0042] "SoJIA (or the juvenile form of Still's disease)" is a type of juvenile idiopathic arthritis (JIA) that, in addition to arthritis, also presents with extra-articular manifestations such as fever and rash. It was originally called soJIA or Still's disease. The main extra-articular manifestations include high fever, rheumatic rash, hepatosplenomegaly, lymphadenopathy, and anemia. Other manifestations include inflammation of the pleura, pericardium, and cardiac muscle tissue, and inflammation of the peritoneum is also visible.
[0043] Systemic lupus erythematosus (SLE) is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissues in many parts of the body. Symptoms can range from mild to severe and vary from person to person. Common symptoms include joint pain and swelling, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, fatigue, and a red rash most commonly seen on the face. There are typically disease phases known as the flare phase and periods of remission with few symptoms.
[0044] Kawasaki disease is a syndrome of unknown cause that causes fever and primarily affects children under 5 years of age. It is a form of vasculitis in which blood vessels throughout the body become inflamed. Fever usually lasts longer than five days and is unresponsive to common medications. Other common symptoms include enlarged lymph nodes in the neck, rashes on the genitals, lips, palms, or soles of the feet, and red eyes. Skin on the hands and feet may peel off within three weeks of onset, after which it usually heals. In some children, coronary artery aneurysms may form in the heart.
[0045] Adult-onset Still's disease (AOSD) is a rare, systemic autoinflammatory disorder characterized by the classic triad of symptoms: fever, joint pain, and a prominent salmon-colored, raised rash. This disease is considered a diagnosis of exclusion. The level of the iron-binding protein ferritin may be dramatically elevated in this condition.
[0046] In some embodiments, the patient has abnormally high blood ferritin levels. In some embodiments, the blood ferritin level is at least 300 ng / ml, or at least 350 ng / ml, 400 ng / ml, 450 ng / ml, 500 ng / ml, 550 ng / ml, 600 ng / ml, 650 ng / ml, 684 ng / ml, 700 ng / ml, 720 ng / ml, 740 ng / ml, 750 ng / ml, 760 ng / ml, 784 ng / ml, 800 ng / ml, 820 ng / ml, 840 ng / ml, 850 ng / ml, 860 ng / ml, 884 ng / ml, 900 ng / ml, 950 ng / ml, or 1000 ng / ml.

[0063] In some embodiments, the patient meets two or more of the above criteria. In some embodiments, the patient meets three, four, five or more of the above criteria.
[0064] The amount of antibody disclosed herein that is effective in treatment. The precise dose to be used in the formulation will also depend on the route of administration and the severity of the disease, symptoms, or condition, and should be determined based on the physician's judgment and each patient's situation. The effective dose can be deduced from dose-response curves derived from in vitro or animal model testing systems.
[0065] As a general recommendation, the dose of the antigen-binding peptide disclosed herein administered to patients is typically between 0.1 mg / kg and 100 mg / kg of patient body weight, between 0.1 mg / kg and 20 mg / kg of patient body weight, or between 1 mg / kg and 10 mg / kg of patient body weight. Generally, due to the immune response to exogenous peptides, human antibodies have a longer half-life in the human body than antibodies from other species. Therefore, the dose of human antibodies can usually be reduced and the frequency of administration decreased. Furthermore, the dosage and frequency of administration of the antibodies disclosed herein can be reduced by modifications (e.g., lipidation) to enhance antibody uptake and tissue penetration (e.g., into the brain).
[0066] In some embodiments, the dosage of IMH001 is 0.1 to 25 mg / kg, 0.3 to 20 mg / kg, 0.3 to 15 mg / kg, 0.3 to 10 mg / kg, 0.5 to 20 mg / kg, 1 to 20 mg / kg, 5 to 20 mg / kg, 6 to 20 mg / kg, 6 to 10 mg / kg, or 5 to 10 mg / kg per administration. In some embodiments, the dosage is at least 0.3 mg / kg, or at least 0.6 mg / kg, 1 mg / kg, 1.3 mg / kg, 1.6 mg / kg, 2 mg / kg, 2.3 mg / kg, 2.6 mg / kg, 3 mg / kg, 4 mg / kg, 5 mg / kg, 6 mg / kg, 7 mg / kg, 8 mg / kg, 9 mg / kg, or 10 mg / kg per administration.

In some embodiments, the administered dose is 2 mg / kg, 3 mg / kg, 4 mg / kg, 5 mg / kg, 6 mg / kg, 7 mg / kg, 8 mg / kg, 9 mg / kg, 10 mg / kg, 12 mg / kg, 15 mg / kg, 20 mg / kg, or 25 mg / kg.
[0067] In some embodiments, the application is performed once a day, once every two days, once every three days, once every four days, once a week, twice a week, once every two weeks, once every three weeks, once a month, or once every two months.
[0068] Methods of administering antibodies include, but are not limited to, intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, and oral routes. Antibodies or compositions can be administered via any convenient route, such as by infusion or bolus injection, absorption through epithelial or mucosal linings (e.g., oral mucosa, rectal and intestinal mucosa), and can be administered together with other bioactive agents. Therefore, pharmaceutical compositions containing the antibodies disclosed herein can be administered orally, rectally, parenterally, intracranially, vaginally, intraperitoneally, topically (e.g., by powder, ointment, drops, or transdermal patch), buccally, or as an oral or nasal spray.
[0069] As used in this article, the term “parenteral” refers to administration methods including intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous, and intra-articular injections and infusions.
[0070] Administration can be systemic or local. Alternatively, it is preferable to introduce the disclosed antibodies into the central nervous system via any suitable route, including intraventricular and intrathecal injection; intraventricular injection can be facilitated, for example, by an intraventricular catheter attached to a reservoir (such as an Ommaya reservoir). Pulmonary administration can also be used, for example, by using an inhaler or nebulizer, and formulations containing nebulizers.
[0071] Preferably, the antibodies or compositions disclosed herein are applied topically to the area requiring treatment; this can be achieved, for example, but not limited to, local infusion during surgery, topical application (e.g., in conjunction with postoperative wound dressings), by injection, via catheter, via suppository, or via implantation, said implant being a porous, non-porous, or gel-like material, including membranes such as sialastic membranes or fibers. Preferably, when administering the proteins (including antibodies) disclosed herein, care must be taken to use materials that are not absorbed by the protein.
[0072] In another embodiment, antibodies or compositions can be delivered in vesicles, particularly liposomes (see Langer, 1990, Science 249:1527-1533; Treat et al., Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; see also ibid.).
[0073] In yet another embodiment, the antibody or composition can be delivered in a controlled release system. In one embodiment, a pump can be used (see Sefton, 1987, CRC Crit. Ref. Biomed. Eng. [CRC Biomedical Engineering Qualification Review] 14:201; Buchwald et al., 1980, Surgery [Surgery] 88:507; Saudek et al., 1989, N. Engl. J. Med. [New England Journal of Medicine] 321:574). In another embodiment, polymeric materials may be used (see Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Press, Boca Raton, Florida (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York (1984); Ranger and Peppas, J., 1983, Macromol. Sci. Rev. Macromol. Chem. 23:61; see also Levy et al., 1985, Science 228:190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 71:105). In yet another embodiment, the controlled-release system can be placed near the therapeutic target (i.e., the brain), thus requiring only a portion of the systemic dose (see, for example, Good Son, in Medical Applications of Controlled Release, ibid., Vol. 2, pp. 115-138 (1984)). Other controlled-release systems are discussed in Langer's review (1990, Science 249: 1527-1533).

[0093] The viscosity of anti-GM-CSF antibody formulations can be controlled for subcutaneous, intravenous, or intramuscular administration. Viscosity can be affected by protein concentration and pH. For example, viscosity can increase with increasing protein concentration. Increasing pH can decrease the viscosity of anti-GM-CSF antibody formulations. In some protein formulations, sodium chloride is added to reduce viscosity. Other components that can affect the viscosity of anti-GM-CSF antibody formulations are amino acids, such as histidine and arginine.
[0094] The liquid pharmaceutical formulations described herein can have a variety of viscosities. Methods for measuring the viscosity of liquid pharmaceutical formulations are known to those skilled in the art and may include, for example, a rheometer (e.g., an Anton Paar MCR301 Rheometer with 50 mm, 40 mm, or 20 mm cone fittings). In some embodiments disclosed herein, the viscosity is reported at the high shear limit at a shear rate of 1000 / s. In some embodiments, the liquid pharmaceutical formulation has a viscosity between 1.0 cP ± 10% and 20 cP ± 10%. In some embodiments, the liquid pharmaceutical formulation has a viscosity less than 20 cP, less than 18 cP, less than 15 cP, less than 13 cP, or less than 11 cP. Those skilled in the art will understand that viscosity is temperature-dependent; therefore, unless otherwise stated, the viscosities provided herein are measured at 25°C. In some embodiments, the viscosity of the liquid pharmaceutical preparation is 1.0 cP ± 10%, 2.0 cP ± 10%, 3.0 cP ± 10%, 3.1 cP ± 10%, 3.2 cP ± 10%, 3.5 cP ± 10%, 3.6 cP ± 10%, 3.8 cP ± 10%, 4.0 cP ± 10%, 5.0 cP ± 10%, 5.3 cP ± 10%, 6.0 cP ± 10%, and 6.3 cP at 25°C. ±10%, 6.4cP±10%, 6.8cP±10%, 7.0cP±10%, 7.1cP±10%, 7.4cP±10%, 8.0cP±10%, 9.0cP±10%, 10.0cP±10%, 11.0cP±10%, 12.0cP±10%, 13.0cP±10%, 14.0cP±10%, 15.0cP±10%, or 16cP±10%.

As used herein, the term “microinfusion device” means a subcutaneous delivery device designed to slowly administer large volumes (e.g., up to about 2.5 mL or more) of a therapeutic formulation over an extended period of time (e.g., about 10, 15, 20, 25, 30 or more minutes). See, for example, U.S. Patent Nos. 6,629,949; 6,659,982; and Meehan et al., J. Controlled Release 46:107-116 (1996). Microinfusion devices are particularly suitable for delivering large doses of therapeutic proteins contained in high concentrations (e.g., about 100, 125, 150, 175, 200 mg / mL or higher) or viscous solutions.
[0119] In some embodiments, this disclosure provides a pre-filled syringe comprising any of the liquid formulations described herein. In some embodiments, the syringe is a 1 mL or 2.25 mL long glass syringe filled with a 27-gauge thin-walled needle, a fluorocarbon-coated rubber plunger, and a rubber needle guard.
[0120] In one respect, the liquid pharmaceutical preparations disclosed herein can be stored at room temperature, refrigerated (e.g., 2-8°C) or frozen (e.g., -20°C or -70°C).
[0121] In some embodiments, the formulation of any of the foregoing aspects has properties selected from the group consisting of: (i) the formulation is stable under long-term storage at 50°C, 40°C, 25°C, 5°C, -20°C, -30°C, and -80°C; (ii) the formulation has low viscosity (viscosity less than 10 cP); (iv) the formulation is isotonic to physiological conditions; (v) the formulation is stable and compatible with intravenous or subcutaneous delivery devices and procedures; and (vi) the formulation is stable under long-term storage in glass vials or pre-filled syringes.
[0122] On the one hand, formulations largely retain their physical and chemical stability and biological activity during storage. Shelf life is typically selected based on the expected shelf life of the formulation. Various analytical techniques for measuring protein stability are available in the field and have been reviewed, for example, in: Peptide and Protein Drug Delivery, 247-301, edited by Vincent Lee, Marcel Dekker, Inc., New York, NY, published (1991) and Jones, A. Adv. Drug Delivery Rev. 10:29-90 (1993). Stability can be measured at a selected temperature over a selected time period. For example, liquid formulations are stable at approximately 40°C for at least approximately 3 days, 5 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, or 6 weeks. On the other hand, the liquid preparation is stable at about 5°C and / or 25°C for at least about 1 month, at least about 3 months, at least about 6 months, at least about 9 months, at least about 12 months, at least about 18 months, at least about 24 months, at least about 30 months, or at least about 36 months; and / or at about -20°C and / or -70°C for at least about 1 month, at least about 3 months, at least about 6 months, at least about 9 months, at least about 12 months, at least about 18 months, at least about 24 months, at least about 30 months, at least about 36 months, at least about 42 months, or at least about 48 months. Furthermore, in some embodiments, the liquid preparation may be stable after freezing (to, for example, -80°C) and thawing (e.g., after 1, 2, or 3 freeze-thaw cycles).
[0123] The stability of liquid formulations can be evaluated qualitatively and / or quantitatively in a variety of ways, including evaluating dimer, multimer, and / or aggregate formation (e.g., using size exclusion chromatography (SEC), matrix-assisted laser desorption / ionization time-of-flight mass spectrometry (MALDI-TOF MS), analytical ultracentrifugation, light scattering (photon correlation spectroscopy, dynamic light scattering (DLS), static light scattering, multi-angle laser light scattering (MALLS)), and flow-based microscopy). Imaging; electrical impedance (coulter) counting, light obscuration or other liquid particle counting systems, by measuring turbidity and / or by visual inspection; assessing charge heterogeneity by using cation exchange chromatography (CEX), isoelectric focusing (IEF) (e.g., capillary technique (cIEF)) or capillary zone electrophoresis; N-terminal or C-terminal sequence analysis; mass spectrometry; SDS-PAGE or SEC analysis to compare fragmented, intact and multimeric (i.e., dimer, trimer, etc.) antibodies; peptide mapping (e.g., trypsin or LYS-C) analysis; evaluating the biological activity or antigen-binding function of antibodies; and similar methods. The stability of formulations in solid form can also be evaluated qualitatively and / or quantitatively in a variety of ways, including direct testing, such as identifying crystal structures by X-ray powder diffraction (XRPD); evaluating antibody structures in solid form using Fourier transform infrared spectroscopy (FTIR); and measuring thermal transitions (melting, glass transition, etc.) in lyophilized solids using differential scanning calorimetry (DSC) and indirect testing (such as measuring moisture content via the Karl Fischer test), for example, to infer the likelihood of chemical instability caused by hydrolysis. Instability can involve any or more of the following: aggregation (e.g., non-covalent soluble aggregation, covalent soluble aggregation (e.g., disulfide rearrangement / disordering), insoluble aggregation), deamidation (e.g., Asn deamidation), oxidation (e.g., Met oxidation), isomerization (e.g., Asp isomerization), shearing / hydrolysis / fragmentation (e.g., hinge region fragmentation), succinimide formation, N-terminal extension, C-terminal processing, differential glycosylation, etc.
[0124] Example
[0125] Example 1. IMH001 inhibited the development of MAS and improved symptoms.
[0126] This study was conducted to evaluate the in vivo efficacy of the GM-CSF neutralizing antibody IMH001 (see sequence in Table 1) in delaying disease progression in a NOG-EXL mouse model of macrophage activation syndrome (MAS) induced by CBMC transplantation. This lymphocyte-independent effector-driven MAS mouse model can be established by transplanting human umbilical cord blood (UCB) into NOG-EXL mice. NOG-EXL (NOD.Cg-Prkdc) scid IL2rg tm1Sug Tg(SV40 / HTLV-IL3,CSF2) is based on NOG(NOD.Cg-Prkdc) scid IL2rg tm1Sug A genetically modified strain of NOG-EXL mice was used. This strain exhibited immunodeficiency and persistent overexpression of human IL-3 and GM-CSF, and it could enrich myeloid cell populations, including Dc, monocytes, and macrophages, after human stem cell transplantation. A total of 46 NOG-EXL mice and 8 NOG mice were used in this study.
[0127] Table 1. VH / VL sequence of IMH001
[0128]
[0129] This model demonstrates a progressive disease with many characteristics of MAS, rapidly developing into progressive anemia without the need for exogenous immune stimulation. Therefore, this model can be used to examine the contribution of the monocyte / macrophage arm and identify novel therapeutic strategies against MAS / HLH.
[0130] 1.1 Method
[0131] Prior to remodeling of umbilical cord blood mononuclear cells (CBMCs) pretreated with OKT3 via tail vein injection, five- to six-week-old NOG-EXL mice were irradiated with 1 Gy. Remodeling day was defined as day 0. Starting from week 1 after implantation, NOG-EXL mice were treated with OKT3-pretreated CBMCs via intraperitoneal (ip) of PBS or 10 mg / kg IMH001 every two weeks. Animal body weight, CBC count, and serum ferritin were measured at designated time points.
[0132] One week after reconstruction (day 7), four NOG mice (G1) and 14 NOG-EXL mice (6 G2 mice and 8 G3 mice, respectively) were administered the drug twice a week for 15 weeks. The grouping and administration regimens are shown in Table 2 below:
[0133] Table 2. Grouping and Dosing Regimens
[0134]
[0135] Body weight: The body weight of the mice was measured and recorded weekly after CBMC transplantation.
[0136] CBC Count: Whole blood was collected from mice at weeks 4, 8, and 16 and counted using a CBC machine. A total bone marrow viable cell count was also performed at the end of the study, week 16. Mice were anesthetized with 3%–4% isoflurane prior to blood collection.
[0137] Cytokines measured by MSD method: Serum was collected at weeks 8 and 10 for the determination of IL-1β, IL-6, TNF-α, GM-CSF, IFN-γ, and IL-12. Mice were anesthetized with 3%–4% isoflurane prior to blood collection.
[0138] Ferritin, fibrinogen, and triglycerides: Serum was collected from mice at weeks 8 and 16. Measurements were then performed individually using an ELISA kit. Mice were anesthetized with 3%–4% isoflurane prior to blood collection.
[0139] Experimental endpoint collection: The endpoint was day 112 / week 16. Spleens were collected from all mice in each group and weighed; cell smears from bone marrow, liver, and spleen sections were collected for Wright Giemsastaining to detect the presence of hemophagocytic activity. Activated lymphoid tissue, spleen / lymph nodes, liver, and meninges were collected for H&E sections to detect inflammatory cell infiltration and reduced lymphoid follicles in the spleen / lymph nodes.
[0140] statistics
[0141] All statistical analysis methods used in this project must be consistent with the experimental plan, and results are expressed as mean ± SEM. First, the F-test was used (IDBS E-WorkBook 10.5.0 (64-bit)). IDBS (Analysis of Variance) is used to analyze homogeneity of variance. If the variances are homogeneous (p>0.05), a one-way ANOVA is performed. The t-test is used to compare two groups, and Dunnett's multiple comparisons method is used to compare multiple groups. If the variances are heteroscedastic (p≤0.05), the Kruskal-Wallis nonparametric test is used, the U-test is used to compare two groups (Kruskal-Wallis parametric test shows a significant difference, p≤0.05), and Dunn's multiple comparisons method is used for multiple group comparisons (Kruskal-Wallis parametric test shows no significant difference, p>0.05). p<0.05 is considered significant.
[0142] 1.2 Results
[0143] Shortly after OKT3-pretreated CBMCs were implanted into NOG-EXL mice, the mice developed MAS, characterized by weight loss, a gradual decrease in red blood cell (RBC) count, hemoglobin (HGB) and hematocrit (HCT), and high ferritin.
[0144] 1.2.1 Weight Changes
[0145] However, treatment with IMH001 completely reversed the progression of the disease. Animals were weighed weekly after CBMC implantation.
[0146] No obvious abnormalities were found in any group during the experiment. Figure 1 The figure shows the changes in body weight at each time point in each group. Sustained weight loss was observed in NOG or NOG-EXL mice transplanted with CBMCs as the disease progressed. Compared to the vector control group (G2), the body weight of the IMH001 treatment group (G3: 10 mg / kg) significantly increased from day 63 to day 112 (p<0.05). This result indicates that IMH001 treatment effectively improves weight loss induced by MAS in animals.
[0147] 1.2.2 Peripheral blood and bone marrow cell counts
[0148] Whole blood was collected from mice, and whole blood counts (CBCs) were analyzed at weeks 4, 8, 12, and 16. At the end of the study (week 16), total bone marrow viable cells were also counted. Figure 2 The figures show RBC, HGB, NEUT, and MONO at each time point in each group. As the disease progressed, a sustained decrease in peripheral RBC count, HGB level, and NEUT percentage was observed in NOG-EXL:CBMC transplanted mice, while PLT count and MONO percentage did not change significantly. Following IMH001 treatment, a recovery in the decrease in RBC and NEUT was observed, particularly on day 56, with significantly higher RBC count and HGB level compared to untreated mice (6.45 vs. 8.17, p < 0.001). A decrease in the percentage of monocytes was also observed in the IMH001 treatment group, which was attributed to the pharmacological effect of IMH001.
[0149] Figure 3 Total bone marrow viable cells are shown. Compared to NOG-EXL-untreated mice, there was a trend towards an increase in total bone marrow cells at day 112 (mean 9.55 vs 11.6, p = 0.182). The number of peripheral RBCs continued to decrease in the MAS control group. Treatment with IMH001 effectively improved the number of RBCs in peripheral blood, accompanied by an increase in HGB.
[0150] 1.2.3 Ferritin, fibrinogen, and triglycerides
[0151] Serum was collected from mice at weeks 8 and 16. Figure 4 The figures show ferritin, fibrinogen, and triglycerides at each time point in each group. In NOG-EXL CBMC transplanted mice, ferritin, an indicator of macrophage activation, significantly increased with disease progression, a phenomenon not observed in NOG CBMC transplanted mice. Moreover, IMH001 treatment effectively controlled ferritin levels compared to untreated mice, as observed at weeks 8 and 16. No significant changes in fibrinogen and triglycerides were observed during disease progression or after IMH001 treatment.
[0152] The results showed a significant increase in peripheral blood ferritin in the MAS control group, indicating macrophage activation. Treatment with IMH001 significantly reduced peripheral blood ferritin levels.
[0153] 1.2.4 Histopathological evaluation
[0154] At the end of the study (week 16), cell smears from bone marrow, liver, and spleen sections were collected for Wright-Giemsa staining to detect the presence of hemophagocytic activity. Activated lymphoid tissue / lymph nodes and spleen were collected for H&E staining to assess lymphocyte depletion; the liver and brain / meninges were H&E stained to detect inflammatory cell infiltration. Figure 5 The results are shown in the figure.
[0155] Hemophagocytic activity: Macrophages containing hemosiderin were observed in spleen red pulp sections and bone marrow smears from the MAS control group, indicating hemophagocytic activity. IMH001 treatment can effectively prevent MAS-related hemophagocytic activity.
[0156] Lymphocyte depletion: NOG-EXL mice showed a decrease in the number of lymphoid follicles and germinal centers in the spleen and the number of lymphocytes in the lymph nodes, indicating lymphocyte depletion. IMH001 treatment effectively reduced lymphocyte depletion. Furthermore, a reduction in inflammatory infiltration was observed in the liver and meninges after IMH001 treatment.
[0157] The results showed that 16 weeks after CBMC transplantation, NOG-EXL mice exhibited increased hemophagocytic activity, lymphocyte depletion, and elevated inflammation compared to NOG mice. These histopathological parameters were significantly improved in IMH001-treated mice.
[0158] Hemophagocytic function: Macrophages containing hemosiderin were observed in spleen red pulp sections and bone marrow smears of the MAS control group, indicating hemophagocytic function.
[0159] Lymphocyte depletion: NOG-EXL mice showed a decrease in the number of lymphoid follicles and germinal centers in the spleen and the number of lymphocytes in the lymph nodes, indicating lymphocyte depletion.
[0160] This study showed that, compared with tocilizumab, IMH001 treatment demonstrated efficacy in delaying disease progression across all the aforementioned parameters.
[0161] Example 2. Development of IMH001 formulation
[0162] This example demonstrates the development of a suitable formulation for the clinical use of IMH001 in the treatment of MAS.
[0163] First, three different buffer systems were evaluated for IMH001 at various pH levels: sodium acetate, histidine hydrochloride, and sodium dihydrogen phosphate. All three buffer systems were able to stabilize the antibody, and pH 5.5 to 6.0 appeared to be more beneficial than 6.5 or higher. Histidine hydrochloride and pH 5.8 were selected for further testing.
[0164] The next step involved evaluating various excipients, including sucrose, trehalose, mannitol, proline, arginine hydrochloride, glycine, sodium chloride, PS20, and PS80. Formulations with different excipients were compared based on changes in stability (CEX-HPLC) over one week at 50°C. The results showed that sucrose and proline were similar in performance and slightly better than the other formulations. Sucrose was selected for further development.
[0165] However, it is unclear whether the chosen buffer and excipients would make the protein solubility of IMH001 suitable for subcutaneous injection at high concentrations. Therefore, the solubility and viscosity of the protein at concentrations of 100 mg / ml and 150 mg / ml in a histidine hydrochloride buffer system (pH 5.8) were evaluated.
[0166] In a 20 mmol / L histidine hydrochloride buffer system (pH 5.8), when the protein concentration was 100 mg / ml and 150 mg / ml and the samples were placed at 4 °C and 25 °C for 48 hours, no significant changes were observed in appearance, clarity, OD350, protein concentration and viscosity. The viscosity was less than 10 cP and the clarity was less than 6 NTU.
[0167] The ability of PS80 (polysorbate 80) to improve the durability and stability of candidate formulations at a protein concentration of 100 mg / ml was then tested at different sucrose concentrations. The viscosity of all samples was acceptable, and it decreased with decreasing sucrose concentration.
[0168] After further adjustments to the concentration of each component, the following formulation was determined to be superior to other candidate formulations: 100 mg / ml IMH001, 20 mM histidine, 220 mM sucrose, and 0.02% (w / v) polysorbate 80, pH 5.8. This formulation was used as the stock solution for the following in vivo studies.
