The submitted sequence listing is part of the present specification and is incorporated herein by reference in its entirety. Technical Field

[0003] The field of the present disclosure relates to co-formulations and combination therapies comprising RNA and antibodies or antigen-binding fragments thereof, and methods for stabilizing RNA in compositions comprising β-hexosaminidase. Background Art

[0004] Complement component C5 is a target of several rare diseases, including paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome, neuromyelitis optica, and generalized myasthenia gravis. For example, uncontrolled complement activation in PNH patients leads to the primary clinical manifestation of chronic hemolysis and an increased risk of thromboembolism, resulting in target organ damage and death.

[0005] Complement 5 is a valid target for the treatment of complement-mediated diseases such as generalized myasthenia gravis (gMG), as established by the approval of eculizumab (Eculizumab) for the treatment of patients with gMG. Monotherapy with the anti-C5 antibody pozelimab has been shown to be effective in blocking C5 activity in another disease that is highly sensitive to complement-mediated effects, paroxysmal nocturnal hemoglobinuria (PNH).

[0006] A substantial degree of complement inhibition is required to provide rapid and significant disease suppression and achieve complete and uninterrupted inhibition of C5 throughout the C5-inhibitor dosing interval. Current C5 inhibitor monotherapy does not achieve adequate levels of inhibition.

[0007] Treatments targeting C5 for PNH, such as eculizumab and ravulizumab (Soliris and Ultomiris, Alexion Pharmaceuticals), have shown efficacy. However, in rare cases, eculizumab and ravulizumab are ineffective because polymorphic variations in the gene encoding C5 prevent the C5 protein from being bound by eculizumab or ravulizumab (Nishimura et al., Genetic variants in C5 and poor response to eculizumab. N Engl J Med 2014; 370(7): 632-639). In addition, treatment is burdensome because the drugs are usually administered long-term by IV infusion every 2 weeks or every 8 weeks to maintain efficacy. Furthermore, it has been reported that up to 20% of patients with PNH treated with eculizumab at the labeled maintenance dose (900 mg Q2W IV) require significant increases in dose or dose frequency due to breakthrough hemolysis secondary to incomplete inhibition of C5 (Peffault deLatour et al., Assessing complement blockade in patients with paroxysmal nocturnal hemoglobinuria receiving Eculizumab. Blood 2015; 125(5): 775-783) (Hillmen et al., Long-term safety and efficacy of sustained Eculizumab treatment in patients with paroxysmal nocturnal hemoglobinuria. Br J Haematol 2013; 162(1): 62-73). Although regulatory approval of ravulizumab provides for IV dosing with a frequency of Q8W, patients still experience some hemolytic breakthrough (Lee et al., Ravulizumab (ALXN1210) vs Eculizumab in adult patients with PNH naive to complement inhibitors: the 301 study. Blood 2019; 133(6): 530-539).

[0008] In a phase 2 study (R3918-PNH-1852) in patients with PNH who had not undergone complement therapy, a 30 mg / kg IV loading dose followed by 800 mg SC weekly was effective in reducing serum LDH to <1.5×ULN in all patients and to <1.0 ULN in most patients. However, this regimen represents a relatively high dose of the biologic agent.

[0009] The need for such high anti-C5 mAb doses is driven by the requirement for 100% inhibition, which is achieved through complete target engagement, and high C5 levels (Peffault de Latour, 2015); and to achieve 100% inhibition on a population basis, one must account for inter- and intra-patient variability in C5 concentrations and the presence of enhanced complement activation, which can occur with concurrent disease.

[0010] Cemdisiran is a synthetic small interfering ribonucleic acid (siRNA) targeting C5 messenger ribonucleic acid (mRNA) that is covalently linked to a triantennary N-acetylgalactosamine (GalNAc) ligand. Cemdisiran is designed to inhibit hepatic production of C5 protein when administered by SC injection. C5 is encoded by a single gene and is primarily expressed and secreted by hepatocytes. Through the ribonucleic acid (RNA) interference pathway, cemdisiran leads to degradation of C5 mRNA by RNases, thereby reducing the production of C5 protein and resulting in reduced circulating C5 protein levels. Cemdisiran monotherapy has been found to be insufficiently effective as a single treatment for PNH. Badri et al., Clin Pharmacokinet. 2021; 60(3): 365–78 - Epub 2020 / 10 / 14.

[0011] Combining cemdisiran with recombinant antibodies in a co-formulation that can be conveniently administered by ordinary injection increases the risk of contamination from the antibodies that degrade the cemdisiran molecule.

[0012] Furthermore, treating patients with conditions such as PNH raises the likelihood that a large proportion of such patients will currently be receiving additional anti-C5 antibodies or have recently received such antibodies and therefore have detectable blood concentrations thereof. Experiments have shown that antibodies having a combination of the sequences of eculizumab and pazelizumab are able to form high molecular weight heteromeric complexes with C5, thus posing a risk of forming such complexes in vivo when both antibodies are present in the circulation.

[0013] Results from previous clinical studies have reported adverse reactions (e.g., serum sickness-like reactions, rash) after switching from one C5 mAb to another, particularly after switching from eculizumab to crovalimab (SKY59 / RO7112689 / RG6107), a therapeutic C5 antibody that binds to a different epitope than eculizumab. These reactions have been attributed to the formation of a DTD immune complex containing C5 and two C5 antibodies ( et al.,Thecomplement C5 inhibitor crovalimab in paroxysmal nocturnalhemoglobinuria.Blood 2020;135(12):912-920; et al., The SMART Anti-hC5 Antibody (SKY59 / RO7112689) Shows Good Safety and Efficacy in Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH). Blood 2018a; 132(Suppl 1): 535; U.S. Patent Application US2009 / 0220508). The size of such immune complexes is associated with the occurrence of adverse events. For example, in a study in which anti-drug-antibody (ADA)-positive patients were injected with infliximab, an antibody specific for a target unrelated to the complement system, severe infusion reactions were observed when immune complexes larger than 1000 kDa (>6 antibodies) were detected for one patient, but no severe infusion reactions were observed when only smaller immune complexes (<1000 kDa) were detected in two patients (van der Laken et al., Imaging and serum analysis of immune complex formation of radiolabelled infliximab and anti-infliximab in responders and non-responders to therapy for rheumatoid arthritis. Ann Rheum Dis 2007; 66(2):253-256), suggesting that large DTD immune complexes are more likely to be associated with adverse events. Furthermore, small DTD immune complexes are not expected to be clinically significant based on extrapolation from other autoimmune disease states (e.g., systemic lupus erythematosus), whereby small immune complexes are inefficient in complement activation and interaction with Fcγ receptors and are not deposited in tissues (Wener et al., Immune Complexes in Systemic Lupus Erythematosus (Chapter 19). Systemic Lupus Erythematosus. Academic Press; 2010).

[0014] It is difficult to reduce the possibility of such adverse events. In the COMMODORE-1 clinical trial, there are two groups in which patients are treated with the anti-C5 antibody kovalizumab or eculizumab during the main treatment period of 24 weeks. After the main treatment period, patients in the eculizumab group have the option of switching to kovalizumab treatment. Sixteen percent of the patients who switched from eculizumab to kovalizumab experienced type 3 hypersensitivity (T3H) reactions. T3H reactions and injection-related reactions are not applicable to the eculizumab group because they are respectively related to large DTD complex formation and subcutaneous administration, which are unique to the kovalizumab group.

DETAILED DESCRIPTION

[0105] While combining two C5 inhibitor treatments with complementary mechanisms of action (pazelimab and cemdisiran) offers the advantage of complete inhibition of the C5 pathway at (relatively) low levels of C5 expression, several technical challenges must be overcome to obtain suitable dosing regimens and delivery vehicles for the agents.

[0106] The superior C5 inhibition provided by the compositions and methods of the present disclosure results in the need for less pazyrumab, which in turn results in reduced SC antibody injection volume, reduced dosing frequency, a wider drug administration window for the combination than for pazyrumab monotherapy, and the potential for reduced injection site reactions. In patients requiring chronic and long-term administration, the combination offers the potential to improve compliance and quality of life compared to pazyrumab monotherapy, while still providing maximal inhibition of C5 activity in a greater percentage of patients compared to eculizumab treatment. In addition, as discussed herein, the dosing regimens of the present disclosure avoid the risk of adverse events caused by the formation of large drug-target-drug complexes (e.g., eculizumab-C5-pazyrumab). Co-formulation of the two agents also provides the convenience of only a single subcutaneous injection to administer the two agents together.

[0107] The present disclosure provides stable co-formulations comprising an antibody or its antigen-binding fragment (e.g., Pazerimab) and a C5 iRNA (e.g., Cemdisiran). Co-formulation of antibodies expressed from mammalian host cells and iRNA molecules conjugated to ligands having terminal N-acetylgalactosamine (GalNAc) and / or N-acetylglucosamine (GlcNAc) presents technical challenges. Small amounts of the enzyme β-hexosaminidase, which often contaminates antibody formulations from such host cells, have been shown to catalyze the removal of terminal GalNAc residues from such iRNA ligands. The present disclosure provides stable co-formulations comprising such antibodies and iRNA molecules that overcome this problem, for example, by adjusting the pH from 6 (e.g., 6.5), adding GalNAc and / or GlcNAc; and / or adding arginine (e.g., L-arginine, such as L-arginine HCl).

[0108] In the methods of the present disclosure, the administration of anti-C5 antibodies and C5 iRNA has been designed to rapidly and continuously suppress the concentration of C5 to a pharmacologically inactive level. Generally speaking, anti-C5 monotherapy requires relatively high doses in patients with PNH. The demand for such high anti-C5 mAb doses is driven by two factors. First, C5 levels are high and 100% inhibition is required, which can only be achieved with complete target engagement (Peffault de Latour R et al., Assessing complement blockade in patients with paroxysmal nocturnal hemoglobinuria receiving eculizumab. Blood 2015; 125(5): 775-83); second, in order to achieve 100% inhibition on a population basis, the inter- and intra-patient variability of C5 concentrations and the example of enhanced complement activation (which can occur with concurrent diseases) can be used. The combination of pazelizumab and cemdisiran achieves high complement inhibition with a relatively low dose of antibody. Combining pazelimab and cemdisiran also offers the advantage of achieving low complement levels while administering less pazelimab (relative to pazelimab monotherapy), resulting in reduced SC injection volume, less frequent dosing, a wider window of drug administration than that of pazelimab monotherapy, and the potential for reduced injection site reactions.

[0109] The present disclosure includes dosing regimens for switching from a previous anti-C5 antibody therapy (e.g., eculizumab or ravelizumab) to a C5 iRNA + anti-C5 antibody or antigen-binding fragment thereof therapy of the present disclosure (e.g., pazelizumab + cemdisiran). Pazelizumab has been shown to bind non-competitively to C5 with an antibody having the amino acid sequence of eculizumab (eculizumab*) and therefore has the potential to form heteromeric complexes, including large DTD immune complexes, such as in patients switching from eculizumab to pazelizumab therapy. Large DTD immune complexes are known to cause adverse events, such as serum sickness-like reactions and rash. The dosing regimens of the present disclosure have been designed to reduce the risk of large DTD complex formation and the occurrence of such adverse events. Antigen binding proteins

[0110] As used herein, the term "antibody" refers to an immunoglobulin molecule comprising four polypeptide chains: two heavy chains (HC) and two light chains (LC) interconnected by disulfide bonds (e.g., IgG), e.g., H2M11683N; H2M11686N; H4H12159P; H4H12161P; H4H12163P; H4H12164P; H4H1 2166P; H4H12166P2; H4H12166P3; H4H12166P4; H4H12166P5; H4H12166P6; H4H1 2166P7; H4H12166P8; H4H12166P9; H4H12166P10; H4H12167P; H4H12168P; H4H 12169P; H4H12170P; H4H12171P; H4H12175P; H4H12176P2; H4H12177P2; H4H121 83P2; H2M 11682N; H2M11684N; H2M11694N; H2M11695N; In one embodiment of the present disclosure, each antibody heavy chain (HC) comprises a heavy chain variable region ("HCVR" or "V H ”) (e.g., SEQ ID NO: 2; 18; 34; 50; 66; 82; 98; 98; 122; 98; 138; 146; 122; 146; 146; 138; 154; 170; 186; 202; 218; 234; 250; 266; 274; 290; 306; 322; or 338; or a variant thereof) and a heavy chain constant region; and each antibody light chain (LC) comprises a light chain variable region (“LCVR” or “V L ”) (e.g., SEQ ID NO: 10; 26; 42; 58; 74; 90; 106; 114; 106; 130; 106; 106; 130; 114; 130; 130; 162; 178; 194; 210; 226; 242; 258; 258; 282; 298; 314; 330; or 346; or a variant thereof) and a light chain constant region (CL). V H and V L The V region can be further subdivided into regions of hypervariability, termed complementarity determining regions (CDRs), interspersed with regions that are more conserved, termed framework regions (FRs). H and V L Contains three CDRs and four FRs.

[0125] The present disclosure provides co-formulations comprising: an anti-C5 antibody or antigen-binding fragment thereof (e.g., H2M11683N; H2M11686N; H4H12159P; H4H12161P; H4H12163P; H4H12164P; H4H12166P; H4H12166P2; H4H12166P3; H4H12166P4; H4H12166P5; H4H12166P6 ; H4H12166P7; H4H12166P8; H4H12166P9; H4H12166P10; H4H12167P; H4H12168P; H4H12169P; H4H 12170P; H4H12171P; H4H12175P; H4H12176P2; H4H12177P2; H4H12183P2; H2M11682N; H2M11684N; H2M11694N; H2M11695N; kovalizumab, eculizumab, tertulumab, mubodina or ravulizumab; preferably, pazelizumab); and an iRNA (C5 iRNA) that affects RNA-induced silencing complex (RISC)-mediated cleavage of C5 gene RNA transcripts, such as Cemdisiran (e.g., Cemdisiran / pazelizumab). The C5 gene can be intracellular, such as intracellular in a subject (e.g., a human). The present disclosure provides an iRNA agent contained in a co-formulation of the present disclosure that affects RNA-induced silencing complex (RISC)-mediated cleavage of complement component C5 gene RNA transcripts.

[0126] Cemdisiran is a chemically synthesized double-stranded oligonucleotide sugar conjugate covalently linked to a ligand containing three GalNAc residues to facilitate targeted delivery to the liver. Figure 1 All nucleosides are modified with 2'-deoxy, 2'-methoxy, or 2'-fluoro groups and are linked by 3' to 5' phosphodiester linkages to form the sugar-phosphate backbone of the oligonucleotide.

[0127] The sense strand (A-125167) contains 21 nucleotides, and the antisense strand (A-125647) contains 25 nucleotides. The 3' end of the sense strand is conjugated to a triantennary GalNAc moiety (designated L96) via a phosphodiester linkage.

[0128] The antisense strand (A-125647) contains four phosphorothioate linkages, two consecutive phosphorothioate linkages at the 3' end and two at the 5' end. The sense strand (A-125167) contains two phosphorothioate linkages at the 5' end. The 21 nucleotides of the sense strand hybridize with the complementary 21 nucleotides of the antisense strand, thereby forming a duplex of 21 nucleotide base pairs with a 4-base overhang at the 3' end of the antisense strand. The bases involved in base pair formation are attached to the central point. Cemdisiran is preferably in the form of a salt, such as Na + salt forms, but the present disclosure includes free acid forms as well as other salt forms (e.g., Ca 2+ salts).

[0129] When the concentration of RNAi in a composition (e.g., a co-formulation of the present disclosure) is expressed herein as mass per volume (e.g., mg / ml), the RNAi is in salt form or free acid form. Preferably, when Cemdisiran is so referred to, Cemdisiran is in salt form, preferably Na + Salt form. + The presence of counterions is due to the net negative charge of the ribonucleotide phosphate backbone. The amount of free acid form of cemdisiran can be determined by adding Cemdisiran Na + The concentration of the salt form is obtained by multiplying by 0.9443.

[0130] The structure of cemdisiran sodium (ALN-62643) is shown below, with A-125167 at the top (5'-3') and A-125647 at the bottom (3'-5'): Af, Gf, and Uf = 2'-F ribonucleosides Am, Cm, and Um-2'-OMe ribonucleosides dT = thymidine S = phosphorothioate L96 is

[0131] A C5 iRNA that can be included in a co-formulation of the present disclosure comprises an RNA strand (e.g., an antisense strand) having a region that is about 30 nucleotides in length or less, e.g., at least 15, 15 to 30, 15 to 29, 15 to 28, 15 to 27, 15 to 26, 15 to 25, 15 to 24, 15 to 23, 15 to 22, 15 to 21, 15 to 20, 15 to 19, 15 to 18, 15 to 17, 18 to 30, 18 to 29, 18 to 28, 18 to 27, 18 to 26, 18 to 25, 18 to 24, 18 to 23, 18 to 22, 18 to 21, 18 to 20, 19 to 23 21 to 30, 21 to 29, 21 to 28, 21 to 27, 21 to 26, 21 to 25, 21 to 24, 21 to 23, or 21 to 22 nucleotides, which region is substantially complementary to at least a portion of an mRNA transcript of a C5 gene.

[0132] In one embodiment of the present disclosure, the C5 iRNA is a glycoconjugate comprising a double-stranded RNA complementary to the C5 region, which is conjugated (e.g., via a linker) to a terminal monoantennary, or biantennary, or triantennary N-acetylgalactosamine (GalNAc) group, preferably triantennary N-acetylgalactosamine.

[0133] In one embodiment of the present disclosure, the iRNA agent that may be included in the co-formulation of the present disclosure comprises a single-stranded RNA that interacts with a target RNA sequence (e.g., a C5 target mRNA sequence) to guide the cutting of the target RNA. Without wishing to be bound by theory, it is believed that the long double-stranded RNA introduced into the cell is broken down into siRNA by a type III nuclease called Dicer (Sharp et al. (2001) Genes Dev. 15:485). The ribonuclease III-like enzyme Dicer processes dsRNA into short interfering RNAs of 19 to 23 base pairs with characteristic two-base 3' overhangs (Bernstein, et al., (2001) Nature 409:363). The siRNA is then incorporated into an RNA-induced silencing complex (RISC), where one or more helicases unwind the siRNA duplex, allowing the complementary antisense strand to guide target recognition (Nykanen, et al., (2001) Cell 107:309). After binding to the appropriate target mRNA, one or more endonucleases within RISC cleave the target to induce silencing (Elbashir, et al., (2001) Genes Dev. 15:188). Therefore, in one aspect, the present disclosure relates to single-stranded RNA (siRNA) that is produced within the cell and promotes the formation of the RISC complex to achieve silencing of the target gene, i.e., the C5 gene. Therefore, the term "siRNA" is also used herein to refer to iRNA as described above.

[0134] In another embodiment, the iRNA agent that may be included in the co-formulation of the present disclosure may be a single-stranded siRNA introduced into a cell or organism to inhibit a target mRNA. The single-stranded iRNA agent binds to the RISC endonuclease Argonaute 2, which then cuts the target mRNA. Single-stranded siRNA is typically 15 to 30 nucleotides and is chemically modified.

[0161] As used herein, co-formulation or pharmaceutical co-formulation refers to a formulation comprising an anti-C5 antigen binding protein (e.g., an antibody or antigen-binding fragment thereof), a C5 iRNA, and a pharmaceutically acceptable carrier. Pharmaceutically acceptable carriers include, for example, one or more excipients. In one embodiment of the present disclosure, the co-formulation of the present disclosure is aqueous, i.e., comprises water.

[0162] Pharmaceutical formulations containing anti-C5 antigen binding proteins can be prepared by mixing the antigen binding protein with one or more excipients (see, e.g., Hardman et al. (2001) Goodman and Gilman's The Pharmacological Basis ofTherapeutics, McGraw-Hill, New York, NY; Gennaro (2000) Remington: The Science and Practice of Pharmacy, Lippincott, Williams, and Wilkins, New York, NY; Avis et al. (eds.) (1993) Pharmaceutical Dosage Forms: Parental Medications, Marcel Dekker, NY; Lieberman et al. (eds) (1990) Pharmaceutical Dosage Forms: Tablets, Marcel Dekker, NY; Lieberman et al. (eds.) (1990) Pharmaceutical Dosage Forms: DisperseSystems, Marcel Dekker, NY; Weiner and Kotkoskie (2000) Excipient Toxicity andSafety, Marcel Dekker, Inc., New New York, NY).

[0163] The present invention provides a method for preparing a co-formulation, the method comprising combining: a C5 iRNA (e.g., Cemdisiran or its Na + salt; for example, wherein the C5 iRNA is reconstituted with water from a lyophilized composition thereof), an antibody or antigen-binding fragment thereof that specifically binds to C5 (e.g., pazylimab), a buffer (e.g., histidine), a viscosity reducer (e.g., L-arginine), a stabilizer (e.g., sucrose), and a nonionic surfactant (e.g., polysorbate 80); and optionally, adjusting the pH of the co-formulation to greater than or less than about 6 (e.g., about 6.5±0.2); and optionally, sterile filtering the co-formulation.

[0164] The present disclosure provides methods for preparing co-formulations of the present disclosure, comprising combining an RNAi (e.g., Cemdisiran) with an antibody or antigen-binding fragment (e.g., Pazylimab) (e.g., comprising a detectable amount of a β-hexosaminidase contaminant), and (i) adding GalNAc to the co-formulation and / or (ii) adjusting the pH of the co-formulation to about 6 or less than about 6 (e.g., within 0.5). In one embodiment of the present disclosure, additional excipients, such as buffers, viscosity reducers, stabilizers, and / or surfactants, are also combined. The co-formulations (e.g., Cemdisiran / Pazylimab) produced by such methods are part of the present disclosure. In one embodiment of the present disclosure, the antibody or fragment combined with the other components is initially in a batch containing a β-hexosaminidase contaminant and is diluted to 0.25, 0.5, or 0.75 fold when incorporated into the co-formulation.

[0165] A variety of viscosity reducers known in the art are used with co-formulations. A viscosity reducer is an agent that reduces the viscosity of a formulation. A viscosity reducer can also function as a tonicifier to adjust the osmolarity of the formulation. Such viscosity reducers include adipic acid; an amino acid or a salt thereof; (D- or L-) arginine; L-arginine HCl; (D- or L-) alanine; benzenesulfonic acid; caffeine; a dicarboxylic acid; an ester of citric acid; (D- or L-) glutamic acid; glycine; (D- or L-) histidine; an inorganic salt; L-ornithine; (D- or L-) lysine; proline; (D- or L-) phenylalanine; (D- or L-) serine; NaCl; pyridoxamine; pyridoxine; thiamine chloride phosphate dihydrate; triethyl citrate; (D- or L-) valine; and / or xanthine. In one embodiment of the present disclosure, the amino acid is an L-amino acid, such as L-arginine. L-Arginine acts as both a tonicity agent, a stabilizer, and a viscosity reducer. Arginine HCl reduces the degradation of cemdisiran and allows for a near-isotonic solution.

[0166] Stabilizers include agents that contribute to reducing the degradation (e.g., aggregation) of, for example, antibodies or Fabs. Polyols are sugar alcohols with multiple hydroxyls. Stabilizers include sugars or polyols, such as trehalose, sorbitol, mannitol, taurine, propanesulfonic acid, L-proline, sucrose, glycerol, threitol, maltitol, and / or polyethylene glycol (PEG, e.g., PEG3350).

[0167] Nonionic surfactants include molecules with uncharged head groups. Nonionic surfactants include nonionic surfactants containing polyoxyethylene moieties; sorbitan; polyoxyethylene glycol alkyl ethers, such as octaethylene glycol monododecyl ether; pentaethylene glycol monododecyl ether; polyoxypropylene glycol alkyl ethers; glucoside alkyl ethers, such as decyl glucoside, lauryl glucoside, octyl glucoside; polyoxyethylene glycol octylphenol ethers, such as triton X-100; polyoxyethylene glycol alkylphenol ethers, such as nonoxynol-9; glyceryl alkyl esters, such as glyceryl laurate; polyoxyethylene glycol dehydrated sorbitan. Sugar alcohol alkyl esters, such as polysorbates; Sorbitan alkyl esters, such as spans; Cocamide MEA, cocamide DEA, dodecyldimethylamine oxide; Block copolymers of polyethylene glycol and polypropylene glycol, such as poloxamer; and polyethoxylated tallow amine (POEA); Poloxamer 188, polyethylene glycol 3350, polyethylene glycol (e.g., PEG3350) or polysorbates such as polysorbate 80 (PS80) or polysorbate 20 (PS20). In one embodiment of the present disclosure, the nonionic detergent is polysorbate 20 (PS20), polysorbate 80 (PS80).

[0168] A buffer is a mixture of a weak acid and its conjugate base that resists changes in its pH and thus maintains the pH at a near constant value, or vice versa. A variety of buffers can be used in the co-formulations of the present disclosure, for example, histidine-based buffers, phosphate buffers, or citrate buffers. A histidine-based buffer is a buffer that contains histidine. Some examples of histidine buffers include histidine chloride, histidine hydrochloride, histidine acetate, histidine phosphate, and histidine sulfate.

Combination therapy regimen of anti-C5 and C5 iRNA

[0177] The present disclosure includes methods comprising administering to a subject in need thereof suffering from a disease, disorder, or condition associated with C5 an anti-C5 antibody or antigen-binding fragment thereof in combination with a C5 iRNA (e.g., in a co-formulation comprising both the antibody or fragment and the iRNA, e.g., as set forth herein) in an amount and at a frequency that achieves a safe and effective therapeutic response (combination therapy of the present disclosure).

[0178] In some embodiments, the present disclosure relates to the combined administration of one or more doses of an anti-C5 antibody or antigen-binding fragment thereof (e.g., Pazylimab) and one or more doses of a C5 iRNA (e.g., Cemdisiran). Preferably, administration is performed in a co-formulation of the present disclosure (as discussed herein), e.g., 100:100 or 50:100 (Cemdisiran mg / ml:Pazylimab mg / ml), e.g., in an injection volume of about 2 ml.

[0179] Generally, herein, co-formulations comprising Cemdisiran and Pazyrumab may be referred to in the following forms: 100: 100, 75: 150, or 50: 100. In such notations, when referring to such co-formulations, the first number represents mg / ml Cemdisiran and the second number represents mg / ml Pazyrumab.

[0180] A "dosing regimen" or "combination therapy dosing regimen" refers to a method for treating or preventing a disease or disorder or condition associated with C5, preferably PNH, comprising administering an amount of the combination therapy of the present disclosure at a frequency as discussed herein.

[0181] For example, the present disclosure encompasses methods for administering anti-C5 antibodies or antigen-binding fragments thereof, and C5 iRNA, comprising introducing the agent into a subject, e.g., by injection, e.g., by subcutaneous injection or intravenous infusion, e.g., on a schedule according to any of the dosing regimens discussed herein (e.g., about 400 mg of anti-C5 antibody or antigen-binding fragment (e.g., pazylimab) subcutaneously about every 2 to 4 weeks (± 3, 4, 5, 6, or 7 days) and about 200 mg of iRNA (e.g., cemdisiran) subcutaneously about every 4 weeks (± 3, 4, 5, 6, or 7 days)).

[0182] Thus, the present disclosure provides methods for treating or preventing a C5-related disease or disorder (e.g., dry AMD or MG; preferably PNH) in a subject in need thereof, the methods comprising administering to the subject an anti-C5 antibody or antigen-binding fragment thereof ("anti-C5 Ab") and a C5 iRNA according to: (i) one or more doses of about 400 mg subcutaneously of an anti-C5 Ab (e.g., pazelimab) and about 200 mg subcutaneously of a C5 iRNA (e.g., cemdisiran); (ii) about 400 mg of anti-C5 Ab (e.g., pazylimab) is administered subcutaneously about every 2 weeks, and about 200 mg of C5 iRNA (e.g., cemdisiran) is administered subcutaneously about every 4 weeks. Preferably, a single injection of a co-formulation comprising anti-C5 Ab and C5 iRNA is administered every 4 weeks (Q4W), and a separate additional injection of anti-C5 Ab, but not C5 iRNA, is administered on a biweekly basis (Q2W); (iii) subcutaneously administering about 400 mg of an anti-C5 Ab (e.g., pazylimab) about every 4 weeks and subcutaneously administering about 200 mg of a C5 iRNA (e.g., cemdisiran) about every 4 weeks, preferably a single injection of a co-formulation comprising the anti-C5 Ab and the C5 iRNA about every 4 weeks; or (iv) about 400 mg of anti-C5 Ab (eg, Pazylimab) and about 200 mg of C5 iRNA (eg, Cemdisiran) administered subcutaneously in about 4 ml about every 4 weeks in a 50:100 co-formulation.

[0183] In one embodiment of the present disclosure, the subject is simultaneously administered: About 400 mg of an anti-C5 antibody or antigen-binding fragment (e.g., pazelimumab) subcutaneously approximately every two to four weeks (±3, 4, 5, 6, or 7 days); and • About 200 mg of iRNA (eg, Cemdisiran) subcutaneously approximately every 2 to 4 weeks (eg, 4 weeks) (± 3, 4, 5, 6, or 7 days).

[0184] The present disclosure also includes embodiments wherein the following are concurrently administered to the subject: About 400 mg of anti-C5 antibody or antigen-binding fragment subcutaneously approximately every 2 weeks (± 3, 4, 5, 6, or 7 days); and ● C5 iRNA at a dose of 200 mg subcutaneously every 4 weeks (± 3, 4, 5, 6, or 7 days).

[0185] The present disclosure also includes embodiments wherein the following are concurrently administered to the subject: About 400 mg of anti-C5 antibody or antigen-binding fragment subcutaneously approximately every four weeks (±3, 4, 5, 6, or 7 days); and C5 iRNA at a dose of 200 mg subcutaneously every 4 weeks (±3, 4, 5, 6, or 7 days) (May be referred to herein as "Pazelimab Q4W and Cemdisiran" or "Pazelimab 400 mg SC Q4W + Cemdisiran 200 mg SC Q4W"). Switching from pazelimumab monotherapy

[0186] Dosing regimens, e.g., for treating a disease or disorder or condition associated with C5 (e.g., PNH), comprising anti-C5 and C5 iRNA, for subjects who have previously received pazelimumab monotherapy, e.g., as described herein, may be referred to herein as a "pazelimumab monotherapy switch" regimen.

[0187] In one embodiment of the invention, the regimen is as follows: On day 1 (7 to 8 days after the last dose of pazilimab monotherapy) or when the next dose of pazilimab monotherapy is due, the subject is started on: (1) Pazelimab 400 mg SC and Cemdisiran 200 mg SC every 4 weeks (Q4W); or (2) Pazelimab 400 mg SC every 2 weeks (Q2W) and Cemdisiran 200 mg SC Q4W.

[0188] Pazylimab monotherapy includes treatment of a disease or disorder or condition associated with C5 (preferably PNH) with pazylimab as the sole C5-specific inhibitor, or more specifically, as the sole anti-C5 antibody or antigen-binding fragment (e.g., without both pazylimab and eculizumab). In one embodiment of the present disclosure, prior to receiving the combination treatment of 400 mg of an anti-C5 antibody or antigen-binding fragment SC about every 2, 3, or 4 weeks and 400 mg of a C5 iRNA SC about every 4 weeks as discussed herein, the subject has received a dosing regimen according to the following: (i) one or more doses of about 30 mg / kg of antigen binding protein intravenously (IV); followed by (ii) one or more doses (e.g., weekly) of about 800 mg of pazelimumab subcutaneously (SC) [which may be referred to as a maintenance phase]; e.g., wherein the subject has PNH; or, (a) one or more doses, preferably only one dose, of about 30 mg / kg pazelimab intravenously (IV); followed by (b) one or more doses (e.g., weekly) of 10 mg / kg pazelimab subcutaneously (SC) [may be referred to as the maintenance phase], For example, where a subject suffers from CHAPLE or, (a) one or more doses, preferably only one dose, of about 30 mg / kg of pazelimab intravenously (IV); then (b) Pazelimab, subcutaneous (SC), at one or more doses (e.g., weekly) according to the following: - For body weight (BW) < about 10 kg: about 125 mg; - For BW ≥ 10 kg and < about 20 kg: about 200 mg; -For BW ≥ 20 kg and < about 40 kg: about 350 mg; - For BW ≥ 40 kg and < about 60 kg: about 500 mg; and - For BW ≥ 60 kg: approximately 800 mg; [May be called the maintenance phase] For example, where the subject suffers from CHAPLE; Wherein the subject has received one or more such doses and is switched to the combination therapy at any point (e.g., starting from the maintenance phase). In one embodiment of the present disclosure, the subject begins receiving the combination of anti-C5 and C5 iRNA on the day the next dose of pazyrumab monotherapy is expected to be administered, and also stops the monotherapy at that time. For example, where the subject is switched from pazyrumab monotherapy and receives the first dose of the combination after receiving: (i) one or more doses of about 800 mg of pazelizumab subcutaneously (SC); (ii) one or more doses of about 30 mg / kg pazelimab intravenously (IV); (iii) one or more doses of about 125 mg pazelizumab subcutaneously (SC); (iv) one or more doses of about 200 mg of pazelizumab subcutaneously (SC); (v) one or more doses of approximately: 350 mg pazelimumab subcutaneously (SC); (vi) one or more doses of approximately: 500 mg pazelizumab subcutaneously (SC); (vii) one or more doses of about 800 mg of pazelizumab subcutaneously (SC); (viii) one or more doses of 10 mg / kg pazelizumab subcutaneously (SC), e.g., wherein the first dose of the combination is received on the date the dose labeled (i), (ii), (iii), (iv), (v), (vi), (vii), or (viii) is due, or about 1 week after the last dose of pazelizumab monotherapy is received.

[0189] In one embodiment of the present disclosure, a subcutaneous single therapeutic dose of pazyrumab is administered in a formulation comprising about: 161 to 274 mg / mL or more of pazelizumab, and a pharmaceutically acceptable carrier comprising: a buffer; L-arginine; water; and optionally an oligosaccharide (e.g., sucrose, mannitol, dextrose, glycerol, TMAO (trimethylamine N-oxide), trehalose, ethylene glycol, glycine betaine, xylitol, or sorbitol); and optionally a non-ionic detergent (e.g., polysorbate 20, polysorbate 80), wherein the pH is as high as about 5.8, 6.1, or 5.5 to 6.1; and the viscosity is about 6.8, about 9.6, about 11.9, about 13.2, about 16.7, about 20.6, about 33.0, about 48.4, about 13.2 to 16.7, or about 6.8 to 48.4 at 20° C. After the formulation is introduced into an aqueous intravenous solution (e.g., 0.9% saline), an intravenous dose of pazelimumab monotherapy can be administered. Not receiving complement inhibitors

[0190] Complement inhibitor-naive or -unexperienced patients have never or recently (e.g., not within the last 1, 2, 3, 4, 5, or 6 months or within at least about 4 or 5 half-lives of the last complement inhibitor they received) received a complement inhibitor therapy (e.g., eculizumab, ravulizumab, pazelizumab).

[0191] In one embodiment of the present disclosure, a C5-related disease or disorder or condition (preferably PNH) is treated in a subject who has not received a complement inhibitor by a method comprising administering: On Day 1: a single loading dose of 30 mg / kg intravenously (IV) and (e.g., optionally followed by a delay of at least about 30 minutes) 400 mg subcutaneously (SC) of pazelimab, and cemdisiran 200 mg SC (combined maintenance dose); Starting on day 29 or approximately 4 weeks later: Pazelimumab 400 mg SC every 4 weeks (q4W), and cemdisiran 200 mg SC q4W (e.g., as a cemdisiran / pazelimab co-formulation).

[0192] In one embodiment of the present disclosure, a C5-related disease or disorder or condition (preferably PNH) is treated in a subject who has not received a complement inhibitor by a method comprising administering: (i) on about day 1, a single loading dose of about 30 mg / kg intravenously (IV) of an anti-C5 antibody or antigen-binding fragment, preferably pazyrumab, followed by about 400 mg subcutaneously (SC) of an anti-C5 antibody or fragment and about 200 mg SC of a C5 iRNA, preferably cemdisiran; and (ii) Starting on about day 29, a SC dose of about 400 mg of anti-C5 antibody or fragment Q4W and a SC dose of about 200 mg of C5 iRNA Q4W.

[0193] During the transition from eculizumab or ravelizumab to a therapy comprising an anti-C5 Ab (e.g., pazelizumab) and a C5 iRNA (e.g., cemdisiran), an additional dose of pazelizumab (e.g., a dose of 30 or 60 mg / kg IV) may be administered, for example, if a potential adverse event (AE) caused by a large drug-target-drug (DTD) immune complex is suspected or has occurred, and / or if systemic corticosteroids are administered for a type III hypersensitivity reaction. This additional dose will establish conditions of pazelizumab excess in the circulation and thereby minimize the risk of further immune complex formation. Switching from eculizumab

[0194] For example, as described above, a dosing regimen for a subject who has previously received eculizumab may be referred to herein as an "eculizumab switch" regimen. Preferably, the subject is being treated for a disease or disorder or condition associated with C5, such as PNH.

[0195] In one embodiment of the invention, the eculizumab switch regimen has the following lead-in loading phase and switch phase: Import

[0196] Initially, subjects remained on background therapy with eculizumab at its usual dose / frequency, and cemdisiran alone was introduced as follows: On Day 1 (the day the subject is scheduled to receive eculizumab, preferably while the subject is on a q2w maintenance regimen of eculizumab): Cemdisiran 200 mg SC and eculizumab ≥ 900 mg IV (the subject's usual dose). Note: Eculizumab, if not administered with cemdisiran on Day 1, may be administered up to 2 days after cemdisiran; On Day 15 (±2 days), for subjects on eculizumab q14 (labeled dose regimen): labeled eculizumab dose [for subjects on eculizumab more frequently than q14: patients are dosed within 2 days of their regularly scheduled dose]; Conversion On Day 29 (or week 4 (counted from Day 1) or about 2 weeks later or when the next eculizumab dose is due or about 1 to 2 half-lives of eculizumab): a 60 mg / kg IV loading dose of pazelizumab, and (e.g., optionally followed by a delay of at least about 30 minutes) pazelizumab 400 mg SC and cemdisiran 200 mg SC (e.g., as a cemdisiran / pazelizumab co-formulation); and Starting on day 57 (or week 8, or approximately 4 weeks later): Pazelimumab 400 mg subcutaneously and cemdisiran 200 mg subcutaneously every 4 weeks (± 7 days) (eg, as a cemdisiran / pazelimab co-formulation) [may be referred to as the maintenance phase]

[0197] In one embodiment of the invention, the half-life of eculizumab (e.g., in a subject with PNH) is about 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or 21 days, for example, about 11 days (Wijnsma et al., Pharmacology, Pharmacokinetics and Pharmacodynamics of Eculizumab, and Possibilities for an Individualized Approach to Eculizumab. Clin Pharmacokinet. 2019 Jul; 58(7): 859-874; Al-Ani et al., Eculizumab in the management of paroxysmal nocturnal hemoglobinuria: patient selection and special considerations. Ther Clin Risk Manag. 2016 Aug 1; 12: 1161-70).

[0198] In one embodiment of the present disclosure, the dosing regimen comprises: (i) an initial dose of eculizumab (at a conventional dose for subjects, e.g., ≥ about 900 mg) intravenously (on Day 1; e.g., on the day or up to 2 days before the next dose of eculizumab is due) and about 200 mg of C5 iRNA subcutaneously; (ii) up to about 14 days (±2 days) later, a second dose of eculizumab (at a conventional dose for subjects, e.g., ≥ about 900 mg); (iii) on about day 29 (week 4): an about 60 mg / kg intravenous (IV) dose of anti-C5 Ab, followed by an about 400 mg subcutaneous dose of anti-C5 Ab and an about 200 mg subcutaneous dose of C5 iRNA; and (iv) on day 57 (week 8) and thereafter, about 400 mg subcutaneous dose of anti-C5 Ab approximately every 4 weeks (± 3, 4, 5, 6, or 7 days), and about 200 mg subcutaneous dose of C5 iRNA approximately every 4 weeks (± 3, 4, 5, 6, or 7 days).

[0199] The prescribed dosing regimen for eculizumab for PNH (eg, in subjects 18 years of age or older) is as follows: 600 mg weekly for the first 4 weeks, then A fifth dose of 900 mg is given one week later, followed by ●900 mg every 2 weeks thereafter.

[0200] The prescribed dosing regimen for eculizumab in the treatment of aHUS is as follows: 900 mg weekly for the first 4 weeks, then A fifth dose of 1200 mg is given one week later, followed by ●1200 mg every 2 weeks thereafter.

[0201] Eculizumab is prescribed for the treatment of generalized myasthenia gravis or neuromyelitis optica spectrum disorder as follows: 900 mg weekly for the first 4 weeks, then A fifth dose of 1200 mg is given one week later, followed by ●1200 mg every 2 weeks thereafter. See also Prescribing Information. In one embodiment of the disclosure, the subject has previously received at least 12 weeks of eculizumab treatment.

[0202] In one embodiment of the present disclosure, eculizumab is administered to a subject at a dose obtained from a pharmaceutical formulation comprising 300 mg of eculizumab, polysorbate 80 (6.6 mg) (vegetable source), sodium chloride (263.1 mg), sodium phosphate dibasic (53.4 mg), sodium phosphate monobasic (13.8 mg), and water for injection, USP, at a pH of 7, in a volume of 30 mL. See also Prescribing Information. Switching from ravulizumab

[0203] For example, as described above, a dosing regimen for a subject who has previously received Ravelizumab may be referred to herein as a "Ravelizumab switch" regimen. Preferably, the subject is being treated for a disease or disorder or condition associated with C5, such as PNH.

[0204] In one embodiment of the present disclosure, the ravlizumab switching regimen is as follows: On Day 1 (4 weeks after the last dose of ravulizumab, preferably while subjects are receiving the q8w ravulizumab maintenance regimen): Cemdisiran 200 mg SC; On day 29 or 4 weeks later or 8 weeks after the last dose of ravlizumab or 1 to 2 half-lives of ravlizumab: a single IV loading dose of pazelizumab at 30 mg / kg or 60 mg / kg, and (e.g., optionally followed by a delay of at least about 30 minutes) pazelizumab 400 mg SC and cemdisiran 200 mg SC (e.g., as a cemdisiran / pazelizumab co-formulation); and • Starting on day 57 or 4 weeks later or after 1 to 2 half-lives of ravlizumab: Initiate a maintenance regimen of pazelizumab 400 mg SC every 4 weeks and cemdisiran 200 mg SC (e.g., as a cemdisiran / pazelizumab co-formulation) every 4 weeks.

[0205] In one embodiment of the invention, the half-life of ravulizumab (e.g., in a subject with PNH) is about 32 days (Stern et al., Ravulizumab: a novel C5 inhibitor for the treatment of paroxysmal nocturnal hemoglobinuria. Ther Adv Hematol. 2019 Sep 10; 10: 2040620719874728; Lee et al., Ravulizumab (ALXN1210) vs eculizumab in adult patients with PNH naive to complement inhibitors: the 301 study. Blood. 2019 Feb 7; 133(6): 530-539; Lee et al., Immediate, complete, and sustained inhibition of C5 with ALXN1210 reduces complement-mediated hemolysis in patients with paroxysmal nocturnal hemoglobinuria (PNH): interim analysis of a dose-escalation study[abstract].Blood.2016;128(22).Abstract 2428).

[0206] In one embodiment of the present disclosure, a subject is treated for a disease, disorder or condition associated with C5, preferably PNH, wherein the subject who previously received ravlizumab (e.g., according to a prescribed dosing regimen) and is being switched to a treatment regimen with a different anti-C5 antibody or antigen-binding fragment (anti-C5 Ab), preferably pazelizumab, and a C5 iRNA (the C5 iRNA), preferably cemdisiran, is administered: (i) C5 iRNA 200 mg SC on day 1 (e.g., 4 weeks (±7 days) or 26 days (±7 days) or 27 days (±7 days) or 28 days (±7 days) after the last dose of ravulizumab); (ii) On approximately day 29, a single IV loading dose of 30 mg / kg or 60 mg / kg of anti-C5 Ab. This IV loading dose may be followed by a 30-minute observation period. The IV dose may be followed by an additional loading dose of 400 mg SC of anti-C5 Ab and 200 mg SC of C5 iRNA; (iii) On approximately day 57, start a maintenance regimen of anti-C5 Ab 400 mg SC and C5 iRNA 200 mg SC, and may be followed by, (iv) Thereafter, anti-C5 Ab 400 mg SC and C5 iRNA 200 mg SC were administered approximately every 4 weeks.

[0207] The loading dose of ravulizumab on day 1 can be based on the patient's weight (≥40 kg to <60 kg, 2400 mg IV; ≥60 kg to <100 kg, 2700 mg IV; ≥100 kg, 3000 mg IV). The first maintenance dose, administered 2 weeks after the loading dose, is as follows: (≥40 kg to <60 kg, 3000 mg IV; ≥60 kg to <100 kg, 3300 mg IV; ≥100 kg, 3600 mg IV). Thereafter, the maintenance dose should be administered IV every 8 weeks (±7 days).

[0208] The maintenance dose of ravulizumab subcutaneously for adult patients weighing 40 kg or more (e.g., those with PNH or aHUS) is 490 mg once weekly. The subcutaneous dosing schedule allows for occasional variations of ±1 day from the scheduled dosing date, but subsequent doses should be administered according to the original schedule.

[0209] The prescribed dosing regimen for ravulizumab in the treatment of PNH is as follows: For patients weighing 5 to less than 10 kg, the loading dose is 600 mg and the maintenance dose is 300 mg every 4 weeks. For patients weighing 10 to less than 20 kg, the loading dose is 600 mg and the maintenance dose is 600 mg every 4 weeks. For patients weighing 20 to less than 30 kg, the loading dose is 900 mg and the maintenance dose is 2,100 mg every 8 weeks; For patients weighing 30 to less than 40 kg, the loading dose is 1200 mg and the maintenance dose is 2,700 mg every 8 weeks; For patients weighing 40 to less than 60 kg, the loading dose is 2,400 mg and the maintenance dose is 3,000 mg every 8 weeks. For patients weighing 60 to less than 100 kg, a loading dose of 2,700 mg and a maintenance dose of 3,300 mg every 8 weeks; and For patients weighing 100 kg or more, the loading dose is 3,000 mg and the maintenance dose is 3,600 mg every 8 weeks. See also Prescribing Information.

[0210] In adult patients with PNH who are greater than or equal to 40 kg body weight, the subcutaneous revlizumab maintenance dose can be 490 mg once a week. Patients who are not currently undergoing revlizumab or eculizumab treatment and who weigh ≥ 40 kg at the start of treatment can start a subcutaneous dose of revlizumab approximately 2 weeks after the intravenous revlizumab loading dose. Patients who are currently being treated with eculizumab and who weigh ≥ 40 kg at the time of the next planned eculizumab dose can start a subcutaneous dose of revlizumab approximately 2 weeks after the intravenous revlizumab loading dose. Patients who are currently being treated with revlizumab intravenously (IV) can start a subcutaneous dose of revlizumab approximately 8 weeks after the last intravenous revlizumab maintenance dose. In one embodiment of the present disclosure, the subject has previously received at least 24 weeks of revlizumab treatment. Table C. Summary of Eculizumab and Ravelizumab Switching Regimens *For example, 900 mg of eculizumab (IV)

[0211] As discussed, the subject may have previously received pazelimab monotherapy, e.g., at a subcutaneous (SC) dose of about 800 mg every 1, 2, 3, or 4 weeks (which may have previously received a loading dose of pazelimab, e.g., intravenously), or ravelizumab or eculizumab, e.g., according to a prescribed dosing regimen. Patients who have previously received pazelimab monotherapy, ravelizumab, or eculizumab may be at any stage of the prescribed dosing regimen for the antibodies prior to switching to a combination therapy of the present disclosure. For example, the subject may have received one or more loading doses and / or one or more maintenance doses of eculizumab. In one embodiment of the invention, prior to or on the same day as starting treatment with a monthly regimen of 400 mg of Pazlimab and 200 mg of Cemdisiran, when a subject is switched from eculizumab or Ravlizumab or another anti-C5 antibody or antigen-binding fragment thereof, the subject receives an intravenous loading dose of Pazlimab (e.g., 30 mg / kg or 60 mg / kg) and / or a single SC dose of Cemdisiran (e.g., 200 mg). The transition phase mitigates the risk of forming large DTD (drug-target-drug) immune complexes of Eculizumab-C5-Pazlimab during the switch from Eculizumab to the Pazlimab + Cemdisiran combination or forming large DTD (drug-target-drug) immune complexes of Ravlizumab-C5-Pazlimab during the switch from Eculizumab to the Pazlimab + Cemdisiran combination.

[0212] Pazylimab binds non-competitively to C5 with eculizumab and therefore has the potential to form heteromeric complexes containing large DTD immune complexes. In vitro, neither pazylimab nor eculizumab alone formed higher-order multimers with C5 greater than a 1:2 mAb:C5 complex. Pazylimab was added to preformed internal eculizumab:C5 complexes in the presence of excess pazylimab (5:1:1 pazylimab:internal eculizumab:C5) and in an equimolar ratio of total mAb to C5 (1:1:2 pazylimab:internal eculizumab:C5). With pazylimab in excess, the majority of samples (approximately 86%) contained free antibody and trimeric or pentameric complexes (mAb:C5 molar ratio of 2:1 or 3:2, respectively), with the remainder containing large HMW complexes. At equimolar ratios of total mAb and C5, the majority of samples (approximately 86%) contained large HMW complexes greater than pentamers. Although eculizumab and pazelizumab were able to form heteromeric complexes in combination with C5, the presence of excess pazelizumab reduced the formation of large, high-order immune complexes relative to conditions where total mAb and C5 were present at equimolar concentrations.

[0213] When switching from a regimen comprising an antibody that does not significantly compete with pazyrumab for binding to C5 (a non-competing antibody or antigen-binding fragment thereof (N / C Ab), e.g., eculizumab or ravelizumab), a transition phase is designed to mitigate the potential risk of formation of large DTD immune complexes of eculizumab-C5-pazyrumab, e.g., during the switch from eculizumab to the pazyrumab / cemdisiran combination. The transition phase can include an introduction dose of cemdisiran followed by a higher pazyrumab IV loading dose (60 mg / kg) than used in treatment-naive patients (30 mg / kg). The initial dose of cemdisiran (e.g., occurring on day 1) reduces C5 production and thereby reduces circulating levels of total C5 available for potential large DTD complex formation prior to the introduction of pazyrumab. To further minimize risk, the 60 mg / kg pazyrumab IV loading dose establishes a high pazyrumab:eculizumab molar ratio. This excess pazelizumab concentration, relative to equimolar concentrations of total antibody and C5, reduces the formation of high-order DTD immune complexes by ensuring saturation of C5 binding sites with pazelizumab. Based on the mean trough concentrations of eculizumab (prescribing information) and predicted pazelizumab concentrations, this IV loading dose results in a molar ratio of pazelizumab to eculizumab of approximately 17:1.

[0214] In cases where, for example, adverse events [AEs] that may be caused by large DTD (drug-target-drug) immune complexes are suspected and / or systemic corticosteroids are administered for type III hypersensitivity reactions, an additional dose of about 30 mg / kg IV of an anti-C5 antibody or antigen-binding fragment, preferably pazyrumumab, may be included. This additional dose will likely establish conditions of excess pazyrumumab in the circulation and thereby minimize the risk of further immune complex formation.

[0215] Therefore, this disclosure includes: Methods for reducing the likelihood of forming large DTD complexes and / or establishing an excess of pazelimumab (relative to those of an N / C antibody, such as eculizumab or ravelizumab, e.g., a ratio >1:1::pazelimumab:N / C Ab (greater than equimolar), e.g., about 17:1::pazelimumab:N / C Ab) in a subject prior to initiation of a regimen comprising cemdisiran and pazelimumab (as described herein, e.g., pazelimumab 400 mg SC Q4W and cemdisiran 200 mg SC Q4W); and A method for treating or preventing a C5-related disease or disorder (preferably PNH) in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of pazyrumab and a C5 iRNA (preferably cemdisiran), wherein the subject has previously received a treatment regimen comprising an antibody or antigen-binding fragment thereof that does not compete with pazyrumab for binding to C5 (a non-competing antibody or antigen-binding fragment thereof (N / CAb), such as eculizumab or ravlizumab), wherein the subject is administered: (1) a C5 iRNA (e.g., Cemdisiran) dose after the N / C Ab (e.g., Eculizumab or Ravelizumab) dose but before the first dose of Pazyrumab (e.g., Pazyrumab IV (e.g., 60 mg / kg) and / or Pazyrumab 400 mg SC Q4W and Cemdisiran 200 mg SC Q4W); or (1) a dose of C5 iRNA (e.g., Cemdisiran) after the N / C Ab dose but before the first dose of Pazelimab; then (2) an intravenous loading dose of pazelimab (e.g., 60 mg / kg), which is the first dose of pazelimab; or (1) an intravenous loading dose of pazelimab (e.g., 60 mg / kg) and a dose of pazelimab 400 mg SC every 4 weeks and cemdisiran 200 mg SC every 4 weeks; then (2) starting approximately 4 weeks thereafter (and continuing every 4 weeks thereafter), pazelimab 400 mg SC every 4 weeks and cemdisiran 200 mg SC every 4 weeks; or (1) a dose of C5 iRNA (e.g., Cemdisiran) approximately 4 weeks after the N / C Ab dose has been administered and prior to an intravenous loading dose of Pazelimab (e.g., 60 mg / kg) and doses of Pazelimab 400 mg SC Q4W and Cemdisiran 200 mg SC Q4W; then (2) starting approximately 4 weeks thereafter (and continuing every 4 weeks thereafter), Pazelimab 400 mg SC Q4W and Cemdisiran 200 mg SC Q4W; or (1) The dose of C5 iRNA (e.g., Cemdisiran) and non-competing antibody or fragment (N / C Ab) on the day the N / C Ab dose is due; (2) the next dose of N / C Ab, on the day such dose is due; (3) Pazelimab IV loading dose (e.g., 60 mg / kg) and Pazelimab 400 mg SC and Cemdisiran 200 mg SC after approximately 1 to 2 half-lives of N / C Ab or when the next dose of N / C Ab is due; (4) starting 4 weeks thereafter (and continuing every 4 weeks thereafter), pazelimab 400 mg SC Q4W and cemdisiran 200 mg SC Q4W; or (1) a dose of C5 iRNA (e.g., Cemdisiran) after approximately 1 to 2 half-lives of N / C Ab from its last dose, or on the day the next dose of N / C Ab is due, or after half of the interval between doses has passed since the last dose of N / C Ab; (2) after approximately another 1 to 2 half-lives of the N / C Ab, a Pazelimab IV loading dose (e.g., 60 mg / kg), Pazelimab 400 mg SC, and Cemdisiran 200 mg SC; and (3) Starting 4 weeks thereafter (and continuing every 4 weeks thereafter), pazelimab 400 mg SC Q4W and cemdisiran 200 mg SC Q4W.

Device

[0254] The present disclosure also provides an injection device comprising a co-formulation of the present disclosure (e.g., Cemdisiran / Pazerizumab). An injection device is a device that introduces a substance into a patient's body by a parenteral route, such as intramuscularly, subcutaneously, intravitreally, intraocularly, or intravenously. For example, an injection device can be a syringe (e.g., a prefilled syringe or an automatic syringe), which, for example, comprises a barrel or a tube for accommodating a fluid to be injected (e.g., a co-formulation), a needle for puncturing the skin and / or a blood vessel to inject the fluid; and a plunger for pushing the fluid out of the barrel and through the needle hole. In one embodiment of the present disclosure, the injection device comprising the co-formulation is suitable for subcutaneous, intravitreal, or intravenous (IV) injection. Such a device comprises a co-formulation in a cannula or trocar / needle that can be connected to tubing that can be connected to a bag or reservoir for containing a fluid (e.g., saline; or lactated Ringer's solution containing NaCl, sodium lactate, KCl, CaCl2, and optionally dextrose) that is introduced into the patient through the cannula or trocar / needle.

[0255] In one embodiment of the present disclosure, once the trocar and cannula are inserted into a vein of the subject and the trocar is removed from the inserted cannula, the co-formulation can be introduced into the device. The IV device can, for example, be inserted into a peripheral vein (e.g., in the hand or arm); the superior or inferior vena cava, or within the right atrium of the heart (e.g., a central IV); or inserted into the subclavian, internal jugular, or femoral veins and advanced toward the heart, for example, until it reaches the superior vena cava or right atrium (e.g., a central venous line).

[0256] In one embodiment of the present disclosure, the injection device is an automatic syringe, a jet syringe or an external infusion pump. A jet syringe uses a high-pressure narrow liquid jet that penetrates the epidermis to introduce the co-formulation into the patient's body. An external infusion pump is a medical device that delivers the co-formulation into the patient's body in a controlled amount. The external infusion pump can be electrically driven or mechanically driven. Different pumps operate in different ways. For example, a syringe pump contains fluid in the reservoir of a syringe and a movable piston controls fluid delivery, while an elastic pump contains fluid in a retractable balloon reservoir and pressure from the elastic wall of the balloon drives fluid delivery. In a peristaltic pump, a group of rollers squeeze downwards on the length of a flexible tube, pushing the fluid forward. In a multichannel pump, fluid can be delivered from multiple reservoirs at multiple rates. β-Hexosaminidase (β-Hex)
