Description

[Technical Field]

[0001] This invention relates to the conjugation of amanita toxin compounds with cell-binding molecules via branched (side-chain) linkers for better pharmacokinetics in the delivery of conjugated compounds, resulting in highly precise targeted therapy for abnormal cells. It also relates to branched linking methods for conjugating amanita toxin analog molecules to cell-binding ligands, as well as methods for using conjugates in targeted prevention or treatment of cancer, infectious diseases, and immunological disorders. [Background technology]

[0002] Over the past two decades, antibody-drug conjugates (ADCs), which are synergistic combinations of mAbs bound to small molecule chemotherapeutic drugs via stable conjugates, have emerged as a highly promising new class of biopharmaceuticals with a large and rapidly growing clinical pipeline. The three components of an ADC work together to produce a potent oncolytic agent that can directly deliver cytotoxins that would normally be untolerant to cancer cells, thereby allowing the cytodestructive agent to be internalized and released (Non-Patent Literature 1 and 2).

[0003] Early ADC therapy had the problem of shorter treatment durations compared to standard chemotherapy agents. However, technological developments regarding conjugates and the use of cytotoxic agents that are too potent to be administered directly have significantly improved the efficacy of ADCs (Non-Patent Documents 3 and 4). However, off-target toxicity remains a major challenge in the development of ADC drugs (Non-Patent Document 5). For example, in clinical practice, ad-trastuzumab emtansine (T-DM1, "Kadcyla" registered trademark), which uses a stable (non-cleavable) MCC conjugate, has shown great benefit to patients with HER2-positive metastatic breast cancer (mBC), or patients who have already been treated for mBC or who have experienced a recurrence of HER2 tumors within 6 months of adjuvant therapy (Non-Patent Documents 6-8). However, T-DM1 has failed in clinical trials as a first-line treatment for patients with HER2-positive unresectable locally advanced or metastatic breast cancer, and as a second-line treatment for HER2-positive advanced gastric cancer, because the patient benefit was small compared to the efficacy and side effects (Non-Patent Documents 9-12).

[0004] To address the issue of off-target toxicity, research and development in the chemistry and design of ADCs is now expanding beyond just potent payloads to encompass the scope of conjugate-payload compartments and conjugation chemistry, particularly the conjugate-payload activity of ADCs against targeted / target diseases (Non-Patent Documents 13 and 14). Today, many pharmaceutical developers and academic institutions are focusing on establishing reliable, novel, specific conjugates and site-specific ADC conjugation methods that appear to have long circulating half-lives, high efficacy, potentially low off-target toxicity, and a narrow range of in vivo pharmacokinetic (PK) properties of ADCs, as well as improving batch-to-batch consistency in ADC production (Non-Patent Documents 15-19). These specific binding methods reported to date include the incorporation of manipulated cysteine ​​(Non-Patent Documents 20 and 21, Patent Documents 1-5), selenocysteine ​​(Non-Patent Documents 22 and 23, Patent Document 6), cysteine-containing tags including perfluoroaromatic reagents (Non-Patent Document 24), thiolfucose (Non-Patent Document 25), unnatural amino acids (Non-Patent Documents 26-29, Patent Documents 7-17); dibromomalemide (Non-Patent Document 30), bissulfone reagents (Non-Patent Document 31, Patent Documents 18 and 1 9) Conjugation to reduced intermolecular disulfide bonds by recrosslinking with dibromopyridazine (Non-Patent Literature 32), galactosyltransferase and sialyltransferase (Non-Patent Literature 33, Patent Literature 20), formylglycine-producing enzyme (FGE) (Non-Patent Literature 34, Patent Literature 21-25), phosphopantetheinyltransferase (PPTases) (Non-Patent Literature 35), and sortase A (Non-Patent Literature 36); genetically introduced glutamine tags (mTG) using streptoverticillium movalense transglutaminase (Non-Patent Literature 37 and 38, Patent Literature 26) or microbial transglutaminase (MTGase) (Non-Patent Literature 39 and 40, Patent Literature 27 and 28); and enzymes / bacteria that form isopeptide bond-peptide bonds formed on the outside of protein backbone (Non-Patent Literature 41-43).

[0007] We have disclosed several conjugation methods for recrosslinking a pair of thiols by reduction of intermolecular disulfide bonds in natural antibodies, e.g., bromomaleimide and dibromomaleimide conjugates (WO2014 / 009774), 2,3-disubstituted succinic acid / 2-monosubstituted / 2,3-disubstituted fumaric acid or malein conjugates (WO2015 / 155753, WO20160596228), acetylenedicarboxy conjugates (WO2015 / 151080, WO20160596228), or hydrazine conjugates (WO2015 / 151081). ADCs produced by these conjugates and methods exhibit a superior therapeutic index window compared to conventional non-selective conjugates via cysteine ​​or lysine residues on the antibody. Here, we disclose an invention of a conjugate of amanita toxin, including long side-chain conjugates. Long side-chain conjugates can prevent the antibody-drug conjugate from being hydrolyzed by hydrolytic enzymes, such as proteinases or esterases, and can make the conjugate more stable in circulation, thereby reducing side effects.

[0008] Amanita toxins, mainly amatoxins, farotoxins, and virotoxins (Wieland, T., Faulstich, H., CRC Crit. Rev. Biochem. 1978, 5(3):185-260; Vetter, J., Toxicon 1998, 36 (1): 13-24; Weiland, T., and Faulstich, H. 1983. Peptide Toxins from Amanita. p. 585-635. In: Handbook of Natural Toxins, Volume I: Plant and Fungal Toxins. RF Keeler and AT Tu, Ed. Marcel Dekker, Inc. New York, NY, Wieland, T., Int J. Pept. Protein Res., 1983, 22, 257-76), can be potent cytotoxic agents for antibody-drug conjugates (Zhao, R., et al. (WO2017046658). The amanita toxin conjugates of the present invention, including long branched conjugates, can extend the half-life of the conjugate during targeted delivery, minimize exposure to non-target cells, tissues, or organs in the bloodstream, and consequently reduce off-target toxicity, resulting in a wider therapeutic window for the conjugate.

[0009] This invention provides branched binding of amanita toxin to an antibody. It also provides a method for conjugating an antibody with an amanita toxin analog having a side chain linker. [Means for solving the problem]

When 1 to 8 amino acids are used in this application, the amino acid sequence is preferably a protease cleavage recognition sequence.Many cleavage recognition sequences are known in the art; see, for example, Matayoshi et al. Science 247: 954 (1990); Dunn et al. Meth. Enzymol. 241: 254 (1994); Seidah et al. Meth. Enzymol. 244: 175 (1994); Thornberry, Meth. Enzymol. 244: 615 (1994); Weber et al. Meth. Enzymol. 244: 595 (1994); Smith et al. Meth. Enzymol. 244: 412 (1994); and Bouvier et al. Meth. Enzymol. 248: 614 (1995); their disclosures are incorporated herein by reference.

[0062] A "glycoside" is a molecule in which a sugar group is linked to another group via a glycosidic bond through its anomeric carbon. Glycosides can be linked by O-(O-glycoside), N-(glycosylamine), S-(thioglycoside), or C-(C-glycoside) glycosidic bonds. The core empirical formula is C m (H2O) n(where m is different from n, and both m and n are < 36), and here glycosides include glucose (dextrose), fructose (levrose), allose, altrose, mannose, gross, iodose, galactose, talose, galactosamine, glucosamine, sialic acid, N-acetylglucosamine, sulfoquinovose (6-deoxy-6-sulfo-D-glucopyranose), ribose, arabinose, xylose, lyxose, sorbitol, mannitol, sucrose, lactose, maltose, trehalose, maltodextrin, raffinose, glucuronic acid (glucuronide), and stachyose.

It is used herein as a monosaccharide, disaccharide, polyol, or oligosaccharide containing 3 to 6 sugar units.

[0063] As used herein, the term “antibody” refers to a full-length immunoglobulin molecule or a molecule comprising an immunologically active portion of a full-length immunoglobulin molecule, i.e., an antigen-binding site that immune-specifically binds to an antigen or part thereof of a significant target, such targets including, but not limited to, cancer cells or cell populations that produce autoimmune antibodies associated with autoimmune diseases. The immunoglobulins disclosed herein may be any type (e.g., IgG, IgE, IgM, IgD, IgA, and IgY), class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2), or subclass of immunoglobulin molecules. Immunoglobulins may originate from any species; however, preferably, immunoglobulins may be of human, mouse, or rabbit origin. Antibodies useful in the present invention are preferably monoclonal, and include, but are not limited to, polyclonal, monoclonal, bispecific, human, humanized or chimeric antibodies, single-chain antibodies, Fv, Fab fragments, F(ab') fragments, F(ab')2 fragments, fragments generated by Fab expression libraries, anti-idiotype (anti-Id) antibodies, CDRs, and any of the above epitope-binding fragments that bind immunospecifically to cancer cell antigens, viral antigens, or microbial antigens.

[0064] Just as left and right hands are identical except that they are opposite each other along a single axis (simply changing direction does not make hands appear identical), enantiomers, also known as optical isomers, are two stereoisomers that are mirror images of each other but cannot be superimposed (they are not identical). A single chiral atom or similar structural feature within a compound can result in two non-superimal structures, each being a mirror image of the other. The presence of multiple chiral elements in a particular compound increases the number of possible geometric forms, but perfect mirror-image pairs may still exist. A pure enantiomeric compound refers to a sample with only one chirality within the detection limit. In a symmetric environment, enantiomers have identical chemical and physical properties except for their ability to rotate plane-polarized light (+ / -) by equal amounts in opposite directions (although polarization can be considered an asymmetric medium). For this reason, they are sometimes called optical isomers. A mixture of equal portions of an optically active isomer and its enantiomer is called a racemic mixture, and the net rotation of plane-polarized light is zero. This is because the positive rotation of each (+) form is precisely canceled out by the negative rotation of the (-) form. Members of an enantiomer often react differently with other enantiomers. Since many biomolecules are enantiomers, there can be significant differences in the effects of two enantiomers on living organisms. For example, in drugs, often only one of the drug's enantiomers is involved in the desired physiological effect, while the other enantiomer may be less active, inactive, or even harmful. This discovery allows for the development of drugs composed of only one enantiomer ("pure enantio") to enhance pharmacological effects and sometimes eliminate some side effects.

[0065] Isotopes are variations of a particular chemical element with different numbers of neutrons. All isotopes of a given element have the same number of protons in each atom. Each atomic number identifies a particular element, but not an isotope. Atoms of a given element can have a wide range of neutron numbers. The number of nucleons (both protons and neutrons) in the nucleus is the mass number of an atom, and each isotope of a particular element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6. This is because all carbon atoms have 6 protons, so the neutron numbers of these isotopes are 6, 7, and 8, respectively. A hydrogen atom has protium ( 1 H), deuterium ( 2 H), and tritium ( 3 There are three isotopes of protium (H), with deuterium having twice the mass of protium and tritium having three times the mass of protium. Isotope substitution can be used to determine the mechanisms of chemical reactions or to investigate kinetic isotope effects. Isotope substitution can be used to investigate not only metabolic changes of substances in the body (e.g., by metabolic enzymes such as cytochrome P450 or glucuronosyltransferase enzymes), but also how the body is affected by specific xenobiotics / chemicals after administration through mechanisms of absorption and distribution, as well as the excretion pathways and effects of drug metabolites. This study is called pharmacokinetics (PK). Isotope substitution can be used to study the biochemical and physiological effects of drugs. Effects include those that appear in animals (including humans), microorganisms, or combinations of organisms (e.g., infections). This study is called pharmacodynamics (PD). Effects include those that appear in animals (including humans), microorganisms, or combinations of organisms (e.g., infections). Both together influence the administration, benefits, and adverse effects of a drug. Isotopes include elements that are either stable (non-radioactive) or unstable. Isotope substitution of drugs may result in therapeutic effects different from those of the original drug.

[0066] "Pharmacologically" or "pharmaceutically acceptable" means that the corresponding compound or compound composition, when administered appropriately to animals or humans, is not harmful, allergic, or otherwise adverse.

[0067] A "pharmaceutically acceptable solvate" or "solvate" refers to the association of one or more solvent molecules with the disclosed compound. Examples of solvents that form pharmaceutically acceptable solvates include, but are not limited to, water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, and ethanolamine.

[0068] Pharmaceutically acceptable auxiliary materials include all carriers, diluents, adjuvants, or molding agents, such as preservatives, antioxidants, fillers, disintegrants, wetting agents, emulsifiers, suspending agents, solvents, dispersing media, coatings, antibacterial agents, antifungal agents, isotonic agents, and absorption retarders. In the pharmaceutical field, adding these auxiliary materials to active drug components is a common practice. It can be said that adding auxiliary materials to drug components is appropriate unless the auxiliary material is incompatible with the drug-active component. Active auxiliary materials may be added to drug components to obtain favorable results.

[0069] In the present invention, "medicinal salt" refers to salt derivatives of the compound of the present invention. By appropriate modification, the compound of the present invention can be formed into a corresponding acid salt or alkali salt. Medicinal salts include commonly used non-toxic salts or quaternary ammonium compounds, which can be prepared with the compound of the present invention and a corresponding non-toxic inorganic or organic acid. For example, inorganic acids include hydrochloric acid, hydrobromic acid, sulfuric acid, aminosulfonic acid, phosphoric acid, and nitric acid, while organic acids include acetic acid, propioic acid, succinic acid, tartaric acid, citric acid, methanesulfonic acid, benzenesulfonic acid, glucuronic acid, glutamic acid, benzoic acid, salicylic acid, toluenesulfonic acid, oxalic acid, fumaric acid, and lactic acid, and these acids can be used in pharmaceutically acceptable salts. Other salts include ammonium salts such as trometamol, meglumine, and pyrroleethanol, and metal salts such as sodium, potassium, calcium, zinc, and magnesium.

[0070] In the present invention, pharmaceutical salts can be prepared from parent compounds containing acidic or basic residues by conventional chemical methods. Generally, these salts can be obtained by reacting the free acidic or free base form of these compounds with a stoichiometric amount of a suitable base or acid in water, an organic solvent, or a mixture of both. Preferred non-aqueous reaction solvents are generally ether, ethyl acetate, ethanol, isopropanol, or acetonitrile. A list of suitable salts is given in Remington's Pharmaceutical Sciences, 17th edition, Mack Publishing Company, Easton, PA, 1985, page 1418, which is incorporated by reference.

The term "releaseable conjugate" refers to a conjugate comprising at least one bond that can be cleaved under physiological conditions such as pH instability, acid instability, base instability, oxidative instability, metabolic instability, biochemical instability, or enzymatic instability. It is understood that such physiological conditions resulting in bond rupture do not necessarily involve biological or metabolic processes, but instead may include standard chemical reactions such as hydrolysis or substitution reactions, e.g., disulfide bond exchange reactions with intracellular thiols such as glutathione in the millimolar range, which are abundant in endosomes and / or malignant cells, where the pH is lower than the cytoplasmic pH.

The polyalkylene glycol chains not only help the conjugates become more hydrophilic during production, but also prevent the conjugated links from being hydrolyzed by hydrolytic enzymes, such as proteinases or esterases. The lipids can help the conjugates in mammalian blood bind to albumin, and slowly dissociate the conjugates from this complex during blood circulation. Thus, the side chain links of this patent application make the conjugates more stable in circulation. Here, polyalkylene glycols include, but are not limited to, poly(ethylene glycol) (PEG), poly(propylene glycol), and copolymers of ethylene oxide and propylene oxide. Particularly preferred is PEG, and even more particularly preferred is monofunctionally activated hydroxyPEG (e.g., single-termined activated hydroxyl PEG, including hydroxyPEG-monocarboxylic acid, hydroxyPEG-monoaldehyde, hydroxyPEG-monoamine, hydroxyPEG-monohydrazide, hydroxyPEG-monocarbazate, hydroxyl reactive esters, PEG-monoiodoacetamide, hydroxyl PEG-monomaleimide, hydroxyl PEG-monoorthopyridyl disulfide, hydroxyPEG-monoxime, hydroxyPEG-monophenylcarbonate, hydroxyl PEG-monophenylglyoxal, hydroxyl PEG-monothiazolidine-2-thion, hydroxyl PEG-monothioester, hydroxyl PEG-monothiol, hydroxyl PEG-monotriazine, and hydroxyl PEG-monovylsulfone).

The thiol of the cell binder / molecule can be generated via Traut's reagent or thiolactone, which reacts with the amine of the cell binder / molecule to form a thiol, followed simultaneously or sequentially by Lv1, Lv2, Lv3, or Lv 3’ And that's how it reacts.

[0142] Preparation of conjugates of amatoxin analogs and cell-binding molecules via side chain linkage

[0143] Figures 1-26 show the preparation of a conjugate between the cell-binding molecule of the present invention and an amatoxin analog, and the synthetic pathway for generating the conjugate via side-chain linkage.

[0144] The conjugates of formulas (I) and (III) can be prepared via the intermediate compounds of formulas (IV) and (V), respectively. Generally, the amatoxin analogs of formulas (IV) and (V) are synthesized to have Lv1 and Lv2 functional groups that readily react with cell-binding molecules or modified cell-binding molecules. The synthesis of the amatoxin analogs of formulas (IV) and (V), as well as some preparations of formulas (I) and (III), are structurally shown in Figures 1 to 26.

[0145] To synthesize the conjugate of formula (I), the functional group Lv1 on formula (IV) is generally reacted with one or more residues on the cell-binding molecule in an aqueous medium of pH 5-9 at 0-60°C, either with or without the addition of 0-30% of a water-miscible organic solvent (such as DMA, DMF, ethanol, methanol, acetone, acetonitrile, THF, isopropanol, dioxane, propylene glycol, or ethylenediol), followed by dialysis or chromatographic purification to form the conjugate compound of formula (I). Some of the residues of the cell-binding molecule (reacting groups for conjugation) can be obtained by protein engineering.

[0146] The conjugate of formula (III) can also be obtained by a reaction between the functional groups Lv1 and Lv2 of the conjugate of formula (V) and two or more residues of the cell-binding molecule, preferably a pair of free thiols generated by reducing the disulfide bond of the cell-binding molecule in an aqueous medium of pH 5 to 9 with or without 0 to 30% water-miscible (miscible) organic solvent at 0 to 60°C. The pair of free thiols is preferably a pair of disulfide bonds reduced from the interchain disulfide bonds of the cell binder by a reducing agent selected from dithiothreitol (DTT), dithioerythritol (DTE), L-glutathione (GSH), tris(2-carboxyethyl)phosphine (TCEP), 2-mercaptoethylamine (β-MEA), and / or β-mercaptoethanol (β-ME, 2-ME) in an aqueous medium of pH 4 to 9 with or without 0 to 30% water-miscible (miscible) organic solvent.

[0147] The Lv1 and Lv2 reactive groups in formulas (IV) and (V) are, independently, disulfide, thiol, maleimide, halogen-substituted maleimide, haloacetyl, azide, 1-yin, ketone, aldehyde, alkoxyamino, triflate, carbonylimidazole, tosylate, mesylate, 2-ethyl-5-phenylisoxazolium-3'-sulfonate, or carboxylic acid esters of nitrophenol, N-hydroxysuccinimide (NHS), phenol; dinitrophenol, pentafluorophenol, tetrafluorophenol The compounds can be hydroxybenzotriazole, anhydrous, hydrazide groups, or other acid ester derivatives, and can react simultaneously or sequentially with one, two, or more groups of a cell-binding molecule / drug in an aqueous medium of pH 5-9 at 0-60°C, with or without the addition of 0-30% water-soluble (miscible) organic solvent, to produce conjugates of formulas (I) and (III) after column purification or dialysis. The Lv1 and Lv2 reactive groups on formulas (IV) and (V) react immediately with the modified cell-binding molecule in different ways. For example, in the cell binder-tubulicine analog conjugate of formula (I), the disulfide bond-containing bond is achieved by disulfide exchange between the disulfide bond in the modified cell binder and Lv1 and Lv2 having free thiol groups, or by disulfide exchange between the free thiol group of the modified cell binder and the disulfide bond on Lv1 and / or Lv2. To shift the disulfide exchange reaction, the disulfide group is typically a group such as disulfanylpyridine, disulfanyl-nitropyridine, disulfanyl-nitrobenzene, disulfanyl-nitrobenzoic acid, or disulfanyl-dinitrobenzene. The thioether-containing bonds in the conjugates of formulas (I) and (III) are achieved by the reaction of maleimide, haloacetyl, or ethylsulfonyl on a modified cell binder or on the tubulicine analogs of formulas (IV) and (V) with a free thiol group on the tubulicine analogs of formulas (IV) and (V) or on the respective modified cell binders.Bonds containing acid-unstable hydrazones in the conjugate are achieved by methods known in the art (e.g., P. Hamann et al., Cancer Res. 53, 3336-34, 1993; B. Laguzza et al., J. Med. Chem., 32; 548-55, 1959; P. Trail et al., Cancer Res., 57; 100-5, 1997) by the reaction of a carbonyl group on a drug- or modified cell-binding molecule of formula (IV) and formula (V) with a hydrazide residue on a drug- or modified cell-binding molecule of formula (IV) and formula (V). Bonds containing triazoles in the conjugate are achieved via click chemistry (Huisgen cycloaddition) (Lutz, JF. et al., 2008, Adv. Drug Del. Rev.60, 958-70; Sletten, EM et al. This is achieved by the reaction of a 1-yine group on the drug or cell-binding molecule of formulas (IV) and (V) with the azide moiety of another counterpart, via (2011, AccChem. Research 44, 666-76). The oxime bond in the oxime-linked conjugate is achieved by the reaction of a ketone or aldehyde group on the drug or cell-binding molecule of formulas (IV) and (V) with the oxiramine group of another counterpart. The thiol-containing cell-binding molecule can react with drug molecule conjugates of formulas (IV) and (V) having maleimide, haloacetyl, or ethylsulfonyl substituents in aqueous buffer at pH 5.5-9.0. The thiol-containing cell-binding molecule can obtain a conjugate with a disulfide bond by disulfide exchange with drug conjugates of formulas (IV) and (V) having pyridyldithio residues. Cell-binding molecules having a hydroxyl group or a thiol group can react with drug conjugates of formulas (IV) and (V) having a halogen, particularly an alpha-halide of a carboxylate salt, under mild basic conditions, for example, at pH 8.0 to 9.5, to obtain modified drugs having an ether or thioether linkage.The hydroxyl or amino group of the cell-binding molecule can condense with drug conjugates of formulas (IV) and (V) containing a carboxyl group in the presence of a dehydrating agent such as EDC or DCC, yielding an ester bond. The cell-binding molecule containing an amino group can condense with the carboxyl ester groups of NHS, imidazole, nitrophenol, N-hydroxysuccinimide, phenol, dinitrophenol, pentafluorophenol, tetrafluorophenol, difluorophenol, monofluorophenol, pentachlorophenol, triflate, imidazole, dichlorophenol, tetrachlorophenol, 1-hydroxybenzotriazole, tosylate, mesylate, or 2-ethyl-5-phenylisoxazolium-3'-sulfonate on drug conjugates of formulas (IV) and (V), yielding a conjugate via an amide bond.

[0148] The synthesized conjugates can be purified by standard biochemical methods, such as gel filtration using Sephadex G25 or Sephacryl S300 columns, adsorption chromatography, ion exchange, or dialysis. In some cases, when small molecules (e.g., folic acid, melanocyte-stimulating hormone, EGF, etc.) are conjugated with small molecule drugs as cell-binding molecules, they can be purified by chromatography, such as HPLC, medium-pressure column chromatography, or ion exchange chromatography.

[0149] To achieve a higher conjugation yield between the cell-binding molecule, preferably a pair of free thiol pairs on an antibody, and formula (I) or (III), it may be required to add a small amount of water-miscible organic solvent or phase transition agent to the reaction mixture. First, the crosslinking ligator (conjugate) of formula (IV) or formula (V) can be dissolved at a high concentration, for example, 1 to 500 mM, in a water-miscible polar organic solvent, such as different alcohols like methanol, ethanol, or propanol, acetone, acetonitrile, tetrahydrofuran (THF), 1,4-dioxane, dimethylformamide (DMF), dimethylacetamide (DMA), or dimethyl sulfoxide (DMSO). On the other hand, the cell-binding molecule, such as an antibody dissolved at a concentration of 1 to 50 mg / ml in an aqueous buffer at pH 4.0 to 9.5, preferably 6.0 to 8.5, is treated with 0.5 to 20 equivalents of TCEP or DTT for 20 minutes to 48 hours. After reduction, DTT can be removed by SEC chromatography. TCEP can also be removed by SEC chromatography if desired, or it can be retained in the reaction mixture for the next step without purification, but it is preferable to neutralize TCEP with an azide compound such as 4-azidobenzoic acid, 4-(azidomethyl)benzoic acid, or azide-polyethylene glycol (e.g., 2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethanol). Furthermore, in order to achieve cross-linking coupling of cell-binding molecules simultaneously with TCEP reduction, the reduction of antibodies or other cell-binding agents by TCEP can be carried out in the presence of existing drug conjugate molecules of formula (IV) or formula (V).

[0150] The aqueous solution for modifying the cell binding agent is buffered to a pH of 4-9, preferably 6.0-7.5, and may contain non-nucleophilic buffer salts useful within this pH range. Typical buffers include phosphates, acetates, triethanolamine HCl, HEPES, and MOPS buffers, and may further contain additional components such as cyclodextrin, hydroxypropyl-β-cyclodextrin, polyethylene glycol, sucrose, and salts (e.g., NaCl, KCl). After adding the drug conjugate of formula (IV) or formula (V) to the solution containing the reduced cell binding molecule, the reaction mixture is incubated at an ambient temperature of 4°C-45°C, preferably 15°C. The progress of the reaction can be monitored by measuring a decrease in absorption at 252 nm, an increase in absorption at 280 nm, or changes at other appropriate wavelengths. After the reaction is complete, the modified cell binder can be isolated by common methods, such as gel filtration chromatography, ion exchange chromatography, adsorption chromatography, or column chromatography on silica gel or alumina, crystallization, pre-thin layer chromatography, ion exchange chromatography, or HPLC.

[0151] The degree of modification can be evaluated by measuring the absorbance of nitropyridinethion, dinitropyridinedithion, pyridinethion, carboxyamidopyridinedithion, and dicarboxyamidopyridinedithion groups emitted via the UV spectrum. In conjugates without chromophore groups, modification or conjugation reactions can be monitored by LC-MS, preferably ULC-QTOF mass spectrometry, or capillary electrophoresis (CEMS). The side-chain crosslinking conjugates described herein have diverse functional groups that can react with any agent having appropriate substituents, preferably cytotoxic agents. For example, modified cell-binding molecules having amino or hydroxy substituents can react with agents having N-hydroxysuccinimide (NHS) esters, and modified cell-binding molecules having thiol substituents can react with agents having maleimide or haloacetyl groups. Furthermore, modified cell-binding molecules having carbonyl substituents (ketones or aldehydes) can react with agents having hydrazides or alkyloxyamines. Those skilled in the art can easily determine which conjugate to use based on the known reactivity of the available functional groups on the conjugate.

[0153] The cell-binding molecule Cb constituting the conjugate and modified cell-binding agent of the present invention may be any currently known or known molecule that binds, complexes, or reacts with residues of a group of cells to be therapeutically or otherwise biologically modified.

[0154] Cell binding agents include, but are not limited to, large molecular weight proteins such as full-length antibodies (polyclonal or monoclonal), dimers, multimers, multispecific antibodies (e.g., bispecific antibodies); single-chain antibodies; antibody fragments such as Fab, Fab', F(ab')2, Fv [Parham, J. Immunol. 131, 2895-2902 (1983)], fragments obtained by Fab expression libraries, anti-idiotype (anti-Id) antibodies, CDRs, bispecific antibodies, trispecific antibodies, cancer cell antigens, viral antigens, microbial antigens, or specific antigens, and any epitope-binding fragments of the said substances that can recognize, bind to, or express desired biological activity with proteins produced by the immune system; and interferons (e.g., I, II, I). Type II); peptides; lymphokines, e.g., IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, GM-CSF, or interferon-gamma (IFN-γ); hormones, e.g., insulin, TRH (thyroid-stimulating hormone-releasing hormone), MSH (cytostimulating hormone), or steroid hormones such as androgens, estrogens, or melanocyte-stimulating hormone (MSH); growth factors and colony-stimulating factors, e.g., epidermal growth factor (EFG), granulocyte-macrophage colony-stimulating factor (GM-CSF); transforming growth factors (TGF), e.g., TGFα, TGFβ; insulin and insulin-like growth factors (IGF-I, IGF-II), G-CSF, M-CSF, and GM-CSF [Burgess, Immunology] [Today, 5, 155-158 (1984)]; vaccine growth factor (VGF); fibroblast growth factor (FGF); small molecular weight proteins, polypeptides, peptides, and peptide hormones, e.g., bombesin, gastrin, and gastrin-releasing peptides; platelet-derived growth factor; interleukins and cytokines, e.g., interleukin-2 (IL-2), interleukin-6 (IL-6), leukemia inhibitors, granulocyte-macrophage colony-stimulating factor (GM-CSF); vitamins such as folic acid; apolipoproteins and glycoproteins, e.g., transferrin [O'Keefe et al, J. Bio. Chem.]260,932-927(1985)]; sugar-binding proteins or lipoproteins such as lectins; cellular nutrient transport molecules; and small molecule inhibitors, e.g., inhibitors of prostate-specific membrane antigen (PSMA), small molecule tyrosine kinase inhibitors (TKIs), non-peptides, or other cell-binding molecules or substances, e.g., bioactive polymers (Dhar, et al, Proc. Natl. Acad. Sci. 2008, 105, 17356-61), bioactive dendrimers (Lee, et al, Nat. Biotechnol. 2005, 23, 1517-26; Almutairi, et al; Proc. Natl. Acad. Sci. 2009, 106, 685-90), nanoparticles (Liong, et al, ACS Nano, 2008, 19, 1309-12; Medarova, et This includes (al, Nat. Med. 2007, 13, 372-7; Javier, et al, Bioconjugate Chem. 2008, 19, 1309-12), liposomes (Medinai, et al, Curr. Phar. Des. 2004, 10, 2981-9), and viral capsids (Flenniken, et al, Viruses Nanotechnol. 2009, 327, 71-93).

[0155] Generally, if a suitable monoclonal antibody is available, it is preferred as a cell surface binding molecule. The antibody may be derived from mouse, human, humanized, chimeric, or other species.

[0156] The production of antibodies used in this invention includes in vivo, in vitro, or a combination thereof. Methods for preparing anti-receptor peptide polyclonal antibodies are well known, for example, as shown in U.S. Patent No. 4,493,795 (Nestor et al.). A typical method for preparing monoclonal antibodies is to fuse mouse spleen cells isolated from a mouse immunized with a specific antigen with myeloma cells (Kohler, G; Milstein, C. 1975. Nature 256:495-497). Detailed procedures are described in Antibodies - A Laboratory Manual, Harlow and Lane, eds., Cold Spring Harbor Laboratory Press, New York (1988), and the contents of that document are incorporated herein by reference as forming part of this specification. In particular, monoclonal antibodies can be obtained by immunizing mice, rats, hamsters, or other mammals with the antigen of interest, and examples of the antigen of interest include intact target cells, antigens isolated from target cells, whole viruses, weakened whole viruses, and viral proteins. Splenocytes and myeloma cells are fused using PEG6000. The hybridomas obtained after fusion are screened using their sensitivity to HAT (hypoxanthine-aminopterin-thymine). Hybridomas that produce monoclonal antibodies useful for carrying out the present invention are identified by inducing an immune response with specific target cell receptors or by suppressing receptor activity.

[0157] The monoclonal antibodies used in the present invention can be obtained by initiating the culture of monoclonal hybridoma cells in a nutrient medium containing hybridoma cells that secrete antibodies with appropriate antigen specificity. In this culture, it is necessary to maintain sufficient time and conditions for the hybridoma cells to secrete antibodies into the culture medium. After collecting the supernatant of the antibody-containing medium, the antibodies can be isolated by well-known techniques, such as protein A affinity chromatography; anion exchange chromatography, cation exchange chromatography, hydrophobic interaction chromatography, and molecular sieve chromatography (particularly affinity chromatography and molecular sieve chromatography using antigen-crosslinked protein A); centrifugation, precipitation, or standard methods for purifying other proteins.

[0158] Culture media useful for preparing these compositions are well known in the art and commercially available, and include synthetic media. An example of a synthetic medium is Dulbecco's minimal essential medium (DMEM; Dulbecco et al., Virol. 8:396 (1959)) to which 4.5 g m / L of glucose, 0–20 mM of glutamine, 0–20% of fetal bovine serum, ppm amounts of several heavy metals (e.g., Cu, Mn, Fe, or Zn) or / and heavy metals added in salt form, and an antifoaming agent (e.g., polyoxyethylene-polyoxypropylene block copolymer).

[0159] Furthermore, in addition to cell fusion technology, cell lines for antibody production can also be constructed by the following methods. For example, direct transformation of B lymphocytes with oncogenic DNA, or transfection with oncogenic viruses, such as Epstein-Barr virus (EBV, also known as human herpesvirus 4 (HHV-4)) or Kaposi's sarcoma-associated virus (KSHV) (see U.S. Patent Nos. 4341761;4399121;4427783;4444887;4451570;4466917;4472500;4491632;4493890 for details). Monoclonal antibodies can be prepared using antireceptor peptides or peptides containing terminal carboxyl groups based on known methods (see Niman et al., Proc. Natl. Acad. Sci. USA, 80:4949-4953 (1983); Geysen et al., Proc. Natl. Acad. Sci. USA, 82:178-182 (1985); Lei et al., Biochemistry 34(20):6675-6688 (1995) for details). Typically, antireceptor polypeptides or polypeptide analogs can be used alone or conjugated to a crosslinked immunogenic carrier as immunogens for preparing antireceptor polypeptides for monoclonal antibodies.

[0160] There are many other well-known methods for producing monoclonal antibodies as binding molecules in the present invention. Among these, the method for producing fully human antibodies has attracted particular attention. Phage display technology allows for the acquisition of fully human antibodies that specifically bind to known antigens from a fully human antibody library through affinity selection. The literature contains detailed descriptions of phage display technology itself, vector construction, and library screening. For more information, see Dente et al. Gene. 148(1):7-13 (1994); Little et al. Biotechnol Adv. 12(3):539-55 (1994); Clackson et al. Nature 352:264-628 (1991); Huse et al. Science 246:1275-1281 (1989).

[0161] Monoclonal antibodies obtained from non-human species (e.g., mice) using hybridoma technology can be humanized to avoid human anti-mouse antibodies when administered to humans. Among the well-known methods for antibody humanization are the transplantation and remodeling of complementarity-determining regions. For details, see U.S. Patents 5,859,205 and 6,797,492; Liu et al., Immunol Rev. 222:9-27 (2008); Almagro et al., Front Biosci. 1; 13:1619-33 (2008); Lazar et al., Mol Immunol. 44(8):1986-98 (2007); Li et al., Proc. Natl. Acad. Sci. USA. 103(10):3557-62 (2006). The disclosures in the aforementioned literature are incorporated as references. Fully human antibodies can be prepared by antigen immunization against transgenic mice, rabbits, monkeys, and other mammals that possess most of the light and heavy chains of human immunoglobulins. Examples of such mice include Xenomouse (Abgenix, Inc.), HuMab-Mouse (Medarex / BMS), and VelociMouse (Regeneron). For details, see U.S. Patents 6,596,541, 6,207,418, 6,150,584, 6,111,166, 6,075,181, 5,922,545, 5,661,016, 5,545,806, 5,436,149, and 5,569,825. In the course of human treatment, the immunogenicity produced in the human body by chimeric antibodies constructed by integrating mouse antibody variable region genes and human antibody constant region genes is far lower than that of mouse antibodies (Kipriyanov et al., Mol Biotechnol. 26:39-60 (2004); Houdebine, Curr Opin Biotechnol. 13:625-9 (2002)). The disclosures in the aforementioned literature are incorporated as references. Furthermore, antibody affinity and specificity can be improved by inducing specific mutagenesis in the antibody variable region (Brannigan et al., Nat Rev Mol Cell Biol. 3:964-70 (2002); Adams et al., J. Immunol Methods. 231:249-60 (1999)).By partially replacing the constant region of an antibody, its affinity for immunoeffector cells can be effectively enhanced, thereby increasing its cytotoxic effect.

[0162] Immunospecific antibodies against malignant cell antigens can be obtained through commercial channels or several commonly used technical methods, such as chemical synthesis or recombinant expression techniques. Similarly, nucleotide sequences encoding immunospecific antibodies against malignant cell antigens can be obtained through commercial channels such as the GenBank database or other similar databases, publicly available literature, or routine cloning and sequencing.

[0163] Besides antibodies, polypeptides or proteins similarly interact with corresponding receptors or epitopes on the target cell surface by binding, blocking, attacking, or other means, acting as binding molecules. These peptides or proteins do not need to belong to the immunoglobulin family, as long as they can specifically bind to the epitope or its corresponding receptor. These polypeptides are also isolated using techniques similar to those for phage display antibodies (Szardenings, J Recept Signal Transduct Res. 2003;23(4):307-49). Peptide fragments obtained from random peptide libraries have applications similar to those of antibodies and antibody fragments. Polypeptide or protein molecules maintain their antigen-binding specificity by linking to several macromolecules or media via binding molecules. These macromolecules include, but are not limited to, albumin, polymers, liposomes, nanoparticles, or dendrimers.

[0181] In a further objective, the present invention also relates to pharmaceutical compositions for treating cancer, infections, or autoimmune diseases, comprising together the conjugate of the present invention and a pharmaceutically acceptable carrier, diluent, or excipient. Methods for treating cancer, infections, and autoimmune diseases can be carried out in vitro, in vivo, or ex vivo. Examples of in vitro therapies include cell culture treatments to kill all cells except desirable variants that do not express a target antigen, or to kill variants that express an undesirable antigen. Examples of ex vivo therapies include treating hematopoietic stem cells (HSCs) prior to performing a transplant (HSCT) and returning them to the body of the same patient to kill affected or malignant cells. For example, clinical ex vivo treatments to remove cancer cells or lymphocytes from bone marrow prior to autologous transplantation in the treatment of cancer and autoimmune diseases, or to remove T cells and other lymphocytes from allogeneic bone marrow or tissue prior to transplantation to prevent graft-versus-host disease, can be carried out as follows: After obtaining bone marrow cells from a patient or another individual, they are cultured at 37°C for 30 minutes to approximately 48 hours in serum-containing medium to which the conjugate of the present invention is added, so that the concentration range is approximately 1 pM to 0.1 mM. The appropriate concentration conditions and culture time (=dose) can be easily determined by an experienced clinician. After the culture is complete, the bone marrow cells are washed with serum-containing medium and returned to the human body by known methods such as intravenous injection. If the patient is receiving other treatments (e.g., pharmacokinetic chemotherapy or total body irradiation) between the acquisition and reinfusion of bone marrow cells, the processed bone marrow cells are cryopreserved in liquid nitrogen using standard medical equipment.

Radioisotope-labeled antibodies are very useful in receptor-targeted imaging experiments, or can be used directly in relative targeted therapy, for example, as in the invention of antibody-drug conjugates (Wu et al (2005) Nature Biotechnology 23(9):1137-1146). Cell-binding molecules, such as antibodies, can be labeled by binding, chelation, or forming other complex radioisotope metal bonds by the crosslinking conjugates of this application, as described above.

[0232] 7) A pharmaceutically acceptable salt, acid, or derivative of any of the above drugs.

[0233] In yet another embodiment, an immunotoxin can be conjugated to a cell-binding molecule as a synergistic agent. The immunotoxins herein are typically macromolecular drugs that are cytotoxic proteins derived from bacterial or plant proteins, such as diphtheria toxin (DT), cholera toxin (CT), tricosanthine (TCS), diatine, Pseudomonas exotoxin A (ETA'), erythromycin, diphtheria toxin, AB toxin, and type III exotoxin. They may also be highly toxic bacterial pore-forming protoxins that require proteolytic treatment for activation. Examples of such protoxins are proaerolysin and its recombinant form, topsaricin. Topsaricin is a modified recombinant protein designed to be selectively activated by prostatic enzymes, causing local cell death and tissue destruction without damaging adjacent tissues or nerves.

[0234] Other synergistic immunotherapies include checkpoint inhibitors, TCR (T cell receptor) T cells, or CAR (chimeric antigen receptor) T cells, or B cell receptor (BCR), natural killer (NK) cells, or cytotoxic antibody cells, or anti-CD3, CD4, CD8, CD16 (FcγRIII), CD27, CD40, CD40L, CD45RA, CD45RO, CD56, CD57, CD57 bright TNFβ, Fas ligand, MHC class I molecules (HLA-A, B, C), or NKR-P1 are preferably used in conjunction with the conjugate of this patent for synergistic therapy.

[0235] Prescription and application

[0236] The patented conjugate is suitable for formulation in liquid form or for lyophilization and subsequent reconstitution into liquid formulations. The conjugate may constitute 0.01% to 99% by weight as the main component in the liquid formulation or in the formulated lyophilized powder. Generally, liquid formulations containing the conjugate active ingredient at concentrations of 0.1 g / L to 300 g / L for delivery to patients without high levels of antibody aggregation may include one or more polyols (e.g., sugars), buffers having a pH of 4.5 to 7.5, surfactants (e.g., polysorbate 20 or 80), antioxidants (e.g., ascorbic acid and / or methionine), isotonic agents (e.g., mannitol, sorbitol or NaCl), chelating agents such as EDTA, metal complexes (e.g., Zn-protein complexes); biodegradable polymers such as polyesters; preservatives (e.g., benzyl alcohol); and / or free amino acids.

[0237] Suitable buffers for use in formulations include, but are not limited to, organic acid salts such as sodium, potassium, ammonium, or trihydroxyethylamino salts of citric acid, ascorbic acid, gluconic acid, carbonate, tartaric acid, succinic acid, acetic acid, or phthalates; and Tris, tromethamine hydrochloride, sulfate, or phosphate buffers. Furthermore, amino acid cationic components can also be used as buffers. Such amino acid components include, but are not limited to, arginine, glycine, glycylglycine, and histidine. Arginine buffers include arginine acetate, arginine chloride, arginine phosphate, arginine sulfate, arginine succinate, etc. In one embodiment, the arginine buffer is arginine acetate. Examples of histidine buffers include histidine chloride-arginine chloride, histidine acetate-arginine acetate, histidine phosphate-arginine phosphate, histidine sulfate-arginine sulfate, histidine succinate-arginine succinate, etc. The pH of the buffer formulation is 4.5 to 7.5, preferably about 4.5 to about 6.5, and more preferably about 5.0 to about 6.2. In some embodiments, the concentration of the organic acid salt in the buffer is about 10 mM to about 500 mM.

[0238] Polyols, optionally included in pharmaceutical formulations, are substances having multiple hydroxyl groups. Polyols can be used as stabilizing excipients and / or isotonic agents in both liquid and lyophilized formulations. Polyols can protect biopharmaceuticals from physical and chemical degradation pathways. Preferredly excluded cosolvents increase the effective surface tension of the solvent at the protein interface, thereby resulting in the most energetically favorable structural conformation having the smallest surface area. Polyols include sugars (reducing and non-reducing sugars), sugar alcohols, and sugar acids. Reducing sugars contain hemiacetal groups that can reduce metal ions or react covalently with lysine or other amino groups of proteins, while non-reducing sugars lack these properties of reducing sugars. Examples of reducing sugars include fructose, mannose, maltose, lactose, arabinose, xylose, ribose, rhamnose, galactose, and glucose. Non-reducing sugars include sucrose, trehalose, sorbose, melegitose, and raffinose. The sugar alcohol is selected from mannitol, xylitol, erythritol, maltitol, lactitol, erythritol, sreitol, sorbitol, and glycerol. The sugar acid includes L-gluconates and their metal salts. The polyol in the liquid formulation or the prepared lyophilized solid may be 0.0% to 20% by weight. Preferably, a non-reducing sugar, sucrose, or trehalose is selected in the formulation at a concentration of about 0.1% to 15%, with trehalose being preferred over sucrose due to its solution stability.

[0239] The surfactants optionally included in the formulation are polysorbate (polysorbate 20, polysorbate 40, polysorbate 65, polysorbate 80, polysorbate 81, polysorbate 85, etc.), poloxamer (e.g., poloxamer 188, poly(ethylene oxide)-poly(propylene oxide), poloxamer 407, or polyethylene-polypropylene glycol, etc.); triton; sodium dodecyl sulfate (SDS); sodium lauryl sulfate; sodium octyl glycoside; lauryl-, myristyl-, linoleyl-, or stearyl-sulfobetaine; lauryl-, myristyl-, linoleyl-, or stearyl-sarcosine; linoleyl-, myristyl-, or cetyl-betaine; lauroamidopropyl-, co The following are selected: Camidopropyl-, Linoleamidopropyl-, Myristamidopropyl-, Palmimidopropyl-, or Isostearamidopropyl-betaine (e.g., Lauroamidopropyl); Myristamidopropyl-, Palmidopropyl-, or Isostearamidopropyl-dimethylamine; Methyl cocoyl sodium, or Sodium methyl oleyl taurate; Dodecyl betaine, Dodecyldimethylamine oxide, Cocamidopropyl betaine, and Cocoamphoglycinates, the "MONAQUAT" (trademark) series (e.g., Isostearylethylimonium ethosulfate); Polyethyl glycol, Polypropylene glycol, and copolymers of ethylene and propylene glycol (e.g., Pluronics, PF68, etc.). Preferred surfactants are polyoxyethylene sorbitan fatty acid esters such as polysorbate 20, 40, 60, or 80 (Tween 20, 40, 60, or 80). The concentration of the surfactant in the formulation is in the range of 0.0% by weight to about 2.0% by weight. In certain embodiments, the concentration of the surfactant is about 0.01% to about 0.2%. In one embodiment, the concentration of the surfactant is about 0.02%.

[0240] The “preservatives” optionally included in a formulation are compounds that essentially reduce bacterial activity. Examples of potential preservatives include octadecyldimethylbenzylammonium chloride, hexamethonium chloride, benzalkonium chloride (a mixture of alkylbenzyldimethylammonium chlorides in which the alkyl group is a long-chain compound), and benzethonium chloride. Other types of preservatives include aromatic alcohols such as phenol, butyl, and benzyl alcohol, alkylparabens such as methyl or propylparaben, catechol, resorcinol, cyclohexanol, 3-pentanol, and m-cresol. The amount of preservative in a liquid formulation or prepared lyophilized powder may be 0.0% to 5.0% by weight. In one embodiment, the preservative described herein is benzyl alcohol.

[0241] Suitable free amino acids for use as isotonic or osmotic regulators in bulk raw materials or formulations are selected from, but are not limited to, arginine, cystine, glycine, lysine, histidine, ornithine, isoleucine, leucine, alanine, glycylcyrrhamate, or aspartic acid. Basic amino acids, i.e., those containing arginine, lysine, and / or histidine, are preferred. If the composition contains histidine, it can function as both a buffer and a free amino acid; however, if a histidine buffer is used, it typically contains non-histidine free amino acids, such as a histidine buffer and lysine. The amino acids may be D- and / or L-, but are usually L-isomers. The amino acids may exist as any stable salt, such as a hydrochloride salt of arginine-HCl. The amount of amino acids in the liquid formulation or prepared lyophilized powder can be 0.0% to 30% by weight.

[0242] The formulation may optionally contain methionine, glutathione, cysteine, cystine, or ascorbic acid as antioxidants at a concentration of up to approximately 5 mg / ml in the liquid formulation, or at a concentration of 0.0% to 5.0% by weight in the formulated lyophilized powder. The formulation may optionally contain metal chelating agents, such as EDTA or EGTA, at a concentration of up to approximately 2 mM in the liquid formulation, or at a concentration of 0.0% to 0.3% by weight in the formulated lyophilized powder.

[0243] The final formulation can be adjusted to a preferred pH with a buffering agent (e.g., acids such as HCl, H2SO4, acetic acid, H3PO4, citric acid, or bases such as NaOH, KOH, NH4OH, ethanolamine, diethanolamine, or triethanolamine, sodium phosphate, potassium phosphate, trisodium citrate, or tromethamine). The formulation needs to be controlled to be "isotonic," meaning that the formulation has essentially the same osmotic pressure as human blood. Isotonic formulations generally have an osmotic pressure of about 250-350 mOsm. Isotonicity can be measured, for example, using a vapor pressure or ice-type osmometer. The isotonic agent is selected from mannitol, sorbitol, sodium acetate, potassium chloride, sodium phosphate, potassium phosphate, trisodium citrate, or NaCl. Generally, both the buffer salt and the isotonic agent can account for up to 30% by weight in the formulation.

[0244] Other excipients that may be useful in either the liquid or lyophilized formulation of the patent application include, for example, fucose, cellobiose, maltotriose, melibiose, octulose, ribose, xylitol, arginine, histidine, glycine, alanine, methionine, glutamic acid, lysine, imidazole, glycylglycine, mannosylglycerate, Triton X-100, and Pluoronic. F-127 includes cellulose, cyclodextrin, (2-hydroxypropyl)-β-cyclodextrin, dextran (10, 40 or 70 kD), polydextrose, maltodextrin, Ficol, gelatin, hydroxypropyl meta, sodium phosphate, potassium phosphate, ZnCl2, zinc, zinc oxide, sodium citrate, trisodium citrate, tromethamine, copper, fibronectin, heparin, human serum albumin, protamine, glycerin, glycerol, EDTA, metacresol, benzyl alcohol, phenol, polyhydric alcohol, or hydrogenated forms of carbohydrates having a carbonyl group reduced to a primary or secondary hydroxyl group.

[0245] Other intended excipients that can be used in the aqueous pharmaceutical composition of the patent application include, for example, flavoring agents, antibacterial agents, sweeteners, antioxidants, antistatic agents, lipids such as phospholipids or fatty acids, steroids such as cholesterol, protein excipients such as serum albumin (human serum albumin), recombinant human albumin, gelatin, and casein, and salt-forming counterions such as sodium. These and additional known pharmaceutical excipients and / or additives suitable for use in the formulations of the present invention are well known in the art, as cited, for example, in "The Handbook of Pharmaceutical Excipients, 4th edition, Rowe et al., Eds., American Pharmaceuticals Association (2003)" and "Remington: The Science and Practice of Pharmacy, 21st edition, Gennaro, Ed., Lippincott Williams & Wilkins (2005)."

[0246] Pharmaceutical containers or vessels are used to hold any of the pharmaceutical formulations of the conjugates of the patent application. The containers are vials, bottles, pre-filled syringes, pre-filled syringes, or auto-injector syringes. Liquid formulations can be freeze-dried or drum-dried in the form of cake or powder in borosilicate vials or soda-lime glass vials. Solid powders may also be prepared by efficient spray drying and then packed into vials or pharmaceutical containers for storage and distribution.

[0247] In further embodiments, the present invention provides a method for preparing a formulation, comprising the following steps: (a) lyophilizing a formulation comprising a conjugate, excipients, and a buffer system; and (b) reconstituting the lyophilized mixture from step (a) in a reconstitution medium so that the reconstituted formulation is stable. The formulation from step (a) may further comprise a stabilizer and one or more excipients selected from the group comprising the above-mentioned bulking agents, salts, surfactants, and preservatives. As the reconstitution medium, several diluted organic acids or water, i.e., sterile water or bacteriostatic water for injection (BWFI), can be used. The reconstitution medium can be selected in an amount of about 10 to about 250 mM from the group consisting of water, i.e., sterile water, bacteriostatic water for injection (BWFI), or acetic acid, propionic acid, succinic acid, sodium chloride, magnesium chloride, acidic solutions of sodium chloride, acidic solutions of magnesium chloride, and acidic solutions of arginine.

[0248] The liquid pharmaceutical formulations of the conjugates of this application need to exhibit various predefined properties. Stability is one of the main concerns for liquid pharmaceuticals, as proteins / antibodies tend to form soluble and insoluble aggregates during manufacturing and storage. Furthermore, various chemical reactions (deamination, oxidation, clipping, isomerization, etc.) can occur in solution, potentially leading to increased levels of degradation products and loss of biological activity. Preferably, the conjugates in liquid or lyophilized formulations need to exhibit a shelf life of more than 6 months at 25°C. More preferably, the conjugates, in either liquid or lyophilized formulations, need to exhibit a shelf life of more than 12 months at 25°C. The most preferred liquid formulations should exhibit a shelf life of approximately 24–36 months at 2–8°C, and the lyophilized formulations should exhibit a shelf life of up to approximately 60 months at 2–8°C. Both liquid and lyophilized formulations need to exhibit a shelf life of at least 2 years at -20°C or -70°C.

[0249] In some embodiments, the formulation is stable after freezing (e.g., -20°C or -70°C) and thawing, for example, after one, two, or three freeze-thaw cycles. Stability can be qualitatively and / or quantitatively evaluated by various methods, such as: assessment of drug / antibody (protein) ratio and aggregate formation (e.g., using ultraviolet, size exclusion chromatography, turbidity measurement, and visual inspection); assessment of charge heterogeneity using electrofocusing or capillary zone electrophoresis such as cation exchange chromatography or image capillaries; sequence analysis of amino or carboxyl group ends; mass spectrometry, or matrix-assisted laser desorption / ionization / time-of-flight mass spectrometry (MALDI / TOF MS), or HPLC-MS / MS; SDS-PAGE analysis for comparison of antibody reduction or integrity; peptide mapping (e.g., trypsin or lysine-carbon); and evaluation of the biological activity or antigen-binding function of the antibody. The instability may include one or more of the following: aggregation, deamidation (e.g., Asn deamidation), oxidation (e.g., Met oxidation), isomerization (e.g., Asp isomerization), shear / hydrolysis / fracture (e.g., hinge fracture), succinimide formation, unpaired cysteine, N-terminal extension, C-terminal processing, and catabolic glycosylation.

[0250] The stable conjugate also needs to "maintain its biological activity" in the pharmaceutical formulation, for example, the biological activity of the conjugate at a specific point in time, e.g., 12 months, must be within approximately 20%, preferably within approximately 10% (within the assay error) of the biological activity determined by antigen-binding assays and / or in vitro cytotoxicity assays, etc., at the time the pharmaceutical formulation was prepared.

[0251] For in vivo clinical application, the bis-linked conjugates of the present invention may be provided in the form of a solution or as a lyophilized solid that can be redissolved in sterile water for injection. Examples of appropriate methods of administering the conjugates are as follows: The conjugates are administered intravenously as a bolus daily, weekly, every two weeks, every three weeks, every four weeks, or monthly for 8 to 54 weeks. The bolus dose is dissolved in 50 to 1000 mL of physiological saline, to which human serum albumin may optionally be added (e.g., 0.5 to 1 mL of concentrated human serum albumin solution at 100 mg / mL). The drug dose is approximately 50 μg to 20 mg / kg body weight per week, administered by intravenous injection (each injection in the range of 10 μg to 200 mg / kg). After 4 to 54 weeks of treatment, the patient may accept a second course of treatment. Detailed treatment methods, including the route of administration, excipients, diluents, dosage, and duration of treatment, can be determined by an experienced surgeon.

[0252] Examples of conditions that can be treated by selectively killing cell populations in vivo or ex vivo include any type of cancer, autoimmune diseases, transplant rejection, and infections (including those caused by viruses, bacteria, or parasites).

[0253] The amount of conjugate required to achieve the desired biological effect varies depending on many factors, including the chemical properties, efficacy, and bioavailability of the conjugate, the type of disease, the patient's race, the patient's medical condition, the route of administration, and all other factors that determine the required dosage, including the delivery and regimen used.

[0254] Generally speaking, the bis-linked conjugate of the present invention may be a parenteral formulation dissolved in physiological buffer to contain the conjugate at a concentration of 0.1 to 10% w / v. Typical dose ranges are 1 μg / kg body weight to 0.1 g / kg body weight per day, week, two weeks, three weeks, or month, and preferred dose ranges are 0.01 mg / kg body weight to 25 mg / kg body weight per week, two weeks, three weeks, or month. Preferred drug doses may appropriately depend on variables such as the type and degree of disease or disability progression, the overall health status of the individual patient, the relative biological activity of the selected drug, the dosage form of the compound, the mode of administration (intravenous, intramuscular, or other), the pharmacokinetic characteristics of the drug in the selected mode of administration, and the rate of administration (single injection or continuous infusion) and the administration schedule (frequency of administration within a set period of time).

[0255] The conjugates of the present invention, via the linkers, can also be administered in unit doses, where "unit dose" refers to a single dose administered to one patient. These units can be used in simple and convenient packaging and maintain physical and chemical stability as either the active conjugate itself or a pharmaceutically acceptable composition as described below. Therefore, the typical daily dose range is 0.01 to 100 mg / kg body weight. Generally, the unit dose ranges from 1 to 3000 mg per day, week, two weeks, three weeks, or month. Preferably, the unit dose is 1 mg to 500 mg administered 1 to 4 times per month, and more preferably, 1 mg to 100 mg administered once every week, two weeks, or three weeks. The conjugates given herein can be prepared by adding one or more pharmaceutically acceptable excipients to a pharmaceutical composition. A unit dose of the drug may be administered orally as a tablet, simple capsule, or soft capsule; intranasally as a powder, nasal spray, or aerosol; or cutaneously as, for example, an ointment, cream, lotion, gel, spray, or skin patch.

[0256] In yet another embodiment, a pharmaceutical composition comprising a therapeutically effective amount of a conjugate of formula (I) or formula (III), or any conjugate described herein, may be administered simultaneously with other therapeutic agents such as chemotherapeutic agents, radiotherapy agents, immunotherapeutic agents, autoimmune disease agents, anti-infective agents, or other conjugates for synergistically treating or preventing cancer, autoimmune diseases, or infectious diseases.
