SMALL INTERFERING RNA TARGETING FXI AND USES THEREOFRELATED APPLICATIONS
[0001] This application claims priority to, and the benefit of, International Application No. PCT / CN2024 / 106194, filed July 18, 2024, the contents of which are incorporated herein by reference in their entirety. REFERENCE TO AN ELECTRONIC SEQUENCE LISTING
[0002] The contents of the electronic sequence listing (02170WO_CRF_sequencelisting. xml; Size: 8, 534, 180 bytes; and Date of Creation: July 14, 2025) are herein incorporated by reference in its entirety.BACKGROUND
[0003] Coagulation Factor XI (F11 or FXI) is a clotting factor. FXI is present in plasma as a zymogen, which is a unique plasma coagulation enzyme because it exists as a homodimer consisting of two identical polypeptide chains linked by disulfide bonds. During activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa, a serine protease composed of two heavy and two light chains held together by disulfide bonds. This activated plasma factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX.
[0004] Clotting factors are specialized proteins that are essential for proper clotting, the process by which blood solidifies to stop bleeding. Individuals with factor XI deficiency do not bleed faster or more profusely than healthy individuals, but, because their blood clots poorly, they may have difficulty stopping the flow of blood from a deep or surgical wound. This may be referred to as prolonged bleeding or a prolonged bleeding episode. The severity of symptoms in factor XI deficiency can vary from one person to another and is not clearly related to the blood factor XI level. In most patients, prolonged bleeding episodes only occur after surgery, dental procedures, or trauma. Bleeding tendencies in factor XI deficiency are unpredictable and inconsistent, making the disorder difficult to manage in some cases. Defects in this factor lead to Rosenthal syndrome, a blood coagulation abnormality. Factor XI deficiency is caused by disruptions or changes (mutations) to the F11 gene and can occur in males and females.
[0005] Accordingly, there is a need for therapies for subject having diseases, disorders and symptoms associated with elevated FXI expression levels.SUMMARY

[0044] In some embodiments of the isolated oligonucleotide of the present disclosure, the sense strand is a single stranded RNA molecule. In some embodiments of the isolated oligonucleotide of the present disclosure, the antisense strand is a single stranded RNA molecule. In some embodiments of the isolated oligonucleotide of the present disclosure, both the sense strand and the antisense strand are single stranded RNA molecules.
[0045] In some embodiments, the isolated oligonucleotide of the present disclosure is a small interfering RNA (siRNA) . Accordingly, the disclosure provides siRNAs, wherein the siRNA comprises a sense region and antisense region complementary to the sense region that together form an RNA duplex, and wherein the sense region comprises a sequence at least 70%to 100%identical to a FXI mRNA sequence. Definitions
[0046] “RNAi” or “RNA interference” refers to the process of sequence-specific post-transcriptional gene silencing, mediated by double-stranded RNA (dsRNA) . Duplex RNA siRNA (small interfering RNA) , miRNA (micro RNA) , shRNA (short hairpin RNA) , ddRNA (DNA-directed RNA) , piRNA (Piwi-interacting RNA) , or rasiRNA (repeat associated siRNA) and modified forms thereof are all capable of mediating RNA interference. These dsRNA molecules may be commercially available or may be designed and prepared based on known sequence information, etc. The antisense strand of these molecules can include RNA, DNA, peptide nucleic acid (PNA) , or a combination thereof. These DNA / RNA chimera polynucleotide includes, but is not limited to, a double-strand polynucleotide composed of DNA and RNA that inhibits the expression of a target gene. These dsRNA molecules can also include one or more modified nucleotides, as described herein, which can be incorporated on either strand.
[0047] In the RNAi gene silencing or knockdown process, dsRNA comprising a first (antisense) strand that is complementary to a portion of a target gene and a second (sense) strand that is fully or partially complementary to the first antisense strand is introduced into an organism. After introduction into the organism, the target gene-specific dsRNA is processed into relatively small fragments (siRNAs) and can subsequently become distributed throughout the organism, decrease messenger RNA of target gene, leading to a phenotype that may come to closely resemble the phenotype arising from a complete or partial deletion of the target gene.
[0048] Certain dsRNAs in cells can undergo the action of Dicer enzyme, a ribonuclease III enzyme. Dicer can process the dsRNA into shorter pieces of dsRNA, i.e. siRNAs. RNAi also involves an endonuclease complex known as the RNA induced silencing complex (RISC) . Following cleavage by Dicer, siRNAs enter the RISC complex and direct cleavage of a single stranded RNA target having a sequence complementary to the antisense strand of the siRNA duplex. The other strand of the siRNA is the passenger strand. Cleavage of the target RNA takes place in the middle of the region complementary to the antisense strand of the siRNA duplex. siRNAs can thus down regulate or knock down gene expression by mediating RNA interference in a sequence-specific manner.
[0049] Alternatively, short oligonucleotides such as siRNA can be specifically delivered into a cell, a tissue, or an organ. Once introduced into the cell, tissue, or organ, the short oligonucleotides are recognized by and loaded into RISC to cleave a target RNA.
[0050] As used herein, “target gene” or “target sequence” refers to a gene or gene sequence whose corresponding RNA is targeted for degradation through the RNAi pathway using dsRNAs or siRNAs as described herein. To target a gene, for example using an siRNA, the siRNA comprises an antisense region complementary to, or substantially complementary to, at least a portion of the target gene or sequence, and sense strand complementary to the antisense strand. Once introduced into a cell, the siRNA directs the RISC complex to cleave an RNA comprising a target sequence, thereby degrading the RNA.
[0051] As used herein, “oligonucleotide” , “nucleic acid, ” “nucleotide sequence, ” and “polynucleotide” are used interchangeably and encompass both RNA and DNA, including cDNA, genomic DNA, mRNA, synthetic (e.g., chemically synthesized) DNA or RNA and chimeras of RNA and DNA. The term polynucleotide, nucleotide sequence, or nucleic acid refers to a chain of nucleotides without regard to length of the chain. The nucleic acid can be double-stranded or single-stranded. Where single-stranded, the nucleic acid can be a sense strand or an antisense strand. The nucleic acid can be synthesized using oligonucleotide analogs or derivatives (e.g., inosine or phosphorothioate nucleotides) . Such oligonucleotides can be used, for example, to prepare nucleic acids that have altered base-pairing abilities or increased resistance to nucleases. The present disclosure further provides a nucleic acid that is the complement (which can be either a full complement or a partial complement) of a nucleic acid, nucleotide sequence, or polynucleotide of this disclosure. When dsRNA is produced synthetically, less common bases, such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthine and others can also be used for antisense, dsRNA, and ribozyme pairing. Other modifications, such as modification to the phosphodiester backbone, or the 2’ -fluoro, the 2′-hydroxy or 2’ O-methyl in the ribose sugar group of the RNA can also be made.
[0052] The term “isolated” can refer to a nucleic acid, nucleotide sequence or polypeptide that is substantially free of cellular material, viral material, and / or culture medium (when produced by recombinant DNA techniques) , or chemical precursors or other chemicals (when chemically synthesized) . Moreover, an “isolated fragment” is a fragment of a nucleic acid, nucleotide sequence or polypeptide that is not naturally occurring as a fragment and would not be found in the natural state. “Isolated” does not mean that the preparation is technically pure (homogeneous) , but it is sufficiently pure to provide the polypeptide or nucleic acid in a form in which it can be used for the intended purpose.
[0053] The term “region” or “fragment” is used interchangeably and as applied to an oligonucleotide.
[0054] The FXI mRNA sequence, as described herein, will be understood to mean a full length FXI mRNA nucleotide sequence, unless indicated otherwise. In some embodiments, the FXI mRNA sequence can be a nucleotide sequence of reduced length relative to a reference nucleic acid or nucleotide sequence of the FXI mRNA sequence comprising, consisting essentially of, and / or consisting of a nucleotide sequence of contiguous nucleotides identical or almost identical (e.g., 60%, 70%, 80%, 90%, 92%, 95%, 98%or 99%identical) to the reference nucleic acid or nucleotide sequence. Such a nucleic acid fragment according to the disclosure may be, where appropriate, included in a larger polynucleotide of which it is a constituent. In some embodiments, such fragments can comprise, consist essentially of, and / or consist of oligonucleotides having a length of at least about 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 150, 200, or more consecutive nucleotides of a nucleic acid or nucleotide sequence according to the disclosure.
[0055] As used herein, “complementary” polynucleotides are those that are capable of base pairing according to the standard Watson-Crick complementarity rules. Specifically, purines will base pair with pyrimidines to form a combination of guanine paired with cytosine (G: C) and adenine paired with either thymine (A: T) in the case of DNA, or adenine paired with uracil (A: U) in the case of RNA. For example, the sequence “A-G-T” binds to the complementary sequence “T-C-A. ” It is understood that two polynucleotides may hybridize to each other even if they are not completely complementary to each other, provided that each has at least one region that is substantially complementary to the other.
[0056] As used herein, the term "substantially complementary" is at least 90% (e.g., 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99%) complementary to the sense strand that is substantially identical to the nucleotide sequence within the defined regions in SEQ ID NO: 1.As used herein, the term “substantially complementary” means that two nucleic acid sequences are complementary at least at about 90%, 95%or 99%of their nucleotides.
[0057] In some embodiments, the two nucleic acid sequences can be complementary at least at 90%, 95%, 96%, 97%, 98%, 99%or more of their nucleotides. In some embodiments, the two nucleic acid sequences can be between 90%to 95%complementary, between 70%to 100%complementary, between 95%and 96%complementary, between 90%and 100%complementary, between 96%to 97%complementary, between 60%to 80%complementary, between 97%and 98%complementary, between 70%and 90%complementary, between 98%and 99%complementary, between 80%and 100%complementary, or between 99%and 100%complementary.
[0058] The term “substantially complementary” can also mean that two nucleic acid sequences, sense strand and antisense strand have sufficient complementarity that allows binding between the sense strand and antisense strand to form a double stranded region comprising of between 19-25 nucleotides in length. The term “substantially complementary” can also mean that two nucleic acid sequences can hybridize under high stringency conditions, and such conditions are well known in the art.
[0059] As used herein, the term "substantially identical" or “sufficient identity” used interchangeably herein, is at least 70%, at least 80%, at least 90%, at least 95%, or at least 99%(e.g., between 70%to 805, 8-%to 90%or 90%to 95%or 95%to 99%or 99%to 100%) identical to the nucleotide sequence within the defined regions in SEQ ID NO: 1.
[0060] As used herein, the term “identity” means that sequences are compared with one another as follows. In order to determine the percentage identity of two nucleic acid sequences, the sequences can first be aligned with respect to one another in order subsequently to make a comparison of these sequences possible. For this e.g., gaps can be inserted into the sequence of the first nucleic acid sequence and the nucleotides can be compared with the corresponding position of the second nucleic acid sequence. If a position in the first nucleic acid sequence is occupied by the same nucleotide as is the case at a position in the second sequence, the two sequences are identical at this position. The percentage identity between two sequences is a function of the number of identical positions divided by the number of all the positions compared in the sequences investigated.
[0061] A “percent identity” or “%identity” as used interchangeably herein, for aligned segments of a test sequence and a reference sequence is the percent of identical components which are shared by the two aligned sequences divided by the total number of components in reference sequence segment, i.e., the entire reference sequence or a smaller defined part of the reference sequence.
[0062] “Nucleotide sequence” and “nucleic acid sequence” are used interchangeably herein, unless indicated otherwise.
[0063] The percentage identity of two sequences can be determined with the aid of a mathematical algorithm. A preferred, but not limiting, example of a mathematical algorithm which can be used for comparison of two sequences is the algorithm of Karlin et al. (1993) , PNAS USA, 90: 5873-5877. Such an algorithm is integrated in the NBLAST program, with which sequences which have a desired identity to the sequences of the present disclosure can be identified. In order to obtain a gapped alignment, as described here, the “Gapped BLAST” program can be used, as is described in Altschul et al. (1997) , Nucleic Acids Res, 25: 3389-3402. If BLAST and Gapped BLAST programs are used, the preset parameters of the particular program (e.g. NBLAST) can be used. The sequences can be aligned further using version 9 of GAP (global alignment program) of the “Genetic Computing Group” using the preset (BLOSUM62) matrix (values -4 to +11) with a gap open penalty of -12 (for the first zero of a gap) and a gap extension penalty of -4 (for each additional successive zero in the gap) . After the alignment, the percentage identity is calculated by expressing the number of agreements as a percentage content of the nucleic acids in the sequence claimed. The methods described for determination of the percentage identity of two nucleic acid sequences can also be used correspondingly, if necessary, on the coded amino acid sequences.
[0064] Useful methods for determining sequence identity are also disclosed in Guide to Huge Computers (Martin J. Bishop, ed., Academic Press, San Diego (1994) ) , and Carillo, H., and Lipton, D., (Applied Math48: 1073 (1988) ) . More particularly, preferred computer programs for determining sequence identity include but are not limited to the Basic Local Alignment Search Tool (BLAST) programs which are publicly available from National Center Biotechnology Information (NCBI) at the National Library of Medicine, National Institute of Health, Bethesda, Md. 20894; see BLAST Manual, Altschul et al., NCBI, NLM, NIH; (Altschul et al., J. Mol. Biol. 215: 403-410 (1990) ) ; version 2.0 or higher of BLAST programs allows the introduction of gaps (deletions and insertions) into alignments; for peptide sequence BLASTX can be used to determine sequence identity; and, for polynucleotide sequence BLASTN can be used to determine sequence identity. Percent identity can be 70%identity or greater, e.g., at least 70%identity, at least 75%identity, at least 80%identity, at least 85%identity, at least 90%identity, at least 95%identity, at least 98%identity, at least 99%identity or 100%identity.
[0065] As used herein, “heterologous” refers to a nucleic acid sequence that either originates from another species or is from the same species or organism but is modified from either its original form or the form primarily expressed in the cell. Thus, a nucleotide sequence derived from an organism or species different from that of the cell into which the nucleotide sequence is introduced, is heterologous with respect to that cell and the cell's descendants. In addition, a heterologous nucleotide sequence includes a nucleotide sequence derived from and inserted into the same natural, original cell type, but which is present in a non-natural state, e.g., a different copy number, and / or under the control of different regulatory sequences than that found in nature.

In some embodiments, the antisense strand comprises or consists essentially of a sequence at least 70%, at least 80%, at least 90%, at least 95%or is 100%identical to a sequence complementary to any fragment of SEQ ID NO: 1. In some embodiments, the sense region and antisense regions are complementary, and base pair to form an RNA duplex structure. The fragment of the FXI mRNA that has percent identity to the sense region of the siRNA, and which is complementary to the antisense region of the siRNA, can be protein coding sequence of the mRNA, an untranslated region (UTR) of the mRNA (5’ UTR or 3’ UTR) , or both.
[0070] In some embodiments, the isolated oligonucleotides of the present disclosure comprises a sense region and antisense region complementary to the sense region that together form an RNA duplex, and the sense region comprises a sequence at least 70%identical to a FXI mRNA sequence. In some embodiments, the sense region is identical to a FXI mRNA sequence.
[0071] As used herein, the term “sense strand” or “sense region” refers to a nucleotide sequence of an siRNA molecule that is partially or fully complementary to at least a portion of a corresponding antisense strand or antisense region of the siRNA molecule. The sense strand of an isolated oligonucleotides of the present disclosure molecule can include a nucleic acid sequence having some percentage identity with a target nucleic acid sequence such as a FXI mRNA sequence. In some cases, the sense region may have 100%identity, i.e., complete identity or homology, to the target nucleic acid sequence. In other cases, there may be one or more mismatches between the sense region and the target nucleic acid sequence. For example, there may be 1, 2, 3, 4, 5, 6, or 7 mismatches between the sense region and the target nucleic acid sequence.
[0072] As used herein, the term “antisense strand” or “antisense region” refers to a nucleotide sequence of the isolated oligonucleotides of the present disclosure, that is partially or fully complementary to at least a portion of a target nucleic acid sequence. The antisense strand of an isolated oligonucleotides of the present disclosure molecule can include a nucleic acid sequence that is complementary to at least a portion of a corresponding sense strand of the isolated oligonucleotides.

[0074] In some embodiments, the sense region of the isolated oligonucleotides of the present disclosure targeting FXI has one or more mismatches between the sequence of the isolated oligonucleotides and the FXI sequence. For example, the sequence of the sense region may have 1, 2, 3, 4 or 5 mismatches between the sequence of the sense region of the isolated oligonucleotides and the FXI sequence. In some embodiments, the FXI sequence is a FXI 3’ untranslated region sequence (3’ UTR) . Without wishing to be bound by theory, it is thought that siRNAs targeting the 3’ UTR have elevated mismatch tolerance when compared to mismatches in the isolated oligonucleotides targeting coding regions of a gene. Further, the isolated oligonucleotides RNAs may be tolerant of mismatches outside the seed region. As used herein, the “seed region” of the isolated oligonucleotides refers to base pairs 2-8 of the antisense region of the isolated oligonucleotides, i.e., the strand of the isolated oligonucleotides that is complementary to and hybridizes to the target mRNA.

[0430] EXAMPLES
[0431] EXAMPLE 1: Design and testing of siRNA compounds against human FXI mRNA.
[0432] Compound Design
[0433] A set of 308 siRNAs compounds against human FXI transcript (Accession No: NM_000128) were designed (see Table 1) .
[0434] Oligonucleotide Synthesis
[0435] Oligonucleotides were prepared by solid-phase synthesis according to standard protocols. Briefly, oligonucleotide synthesis was conducted on a solid support to incorporate each nucleoside phosphoramidites from 3’ -end to 5’ -end to prepare oligo single strands. ETT or BTT was used as an activator for the coupling reaction. Iodine in water / pyridine / THF was used to oxidize phosphite-triester (P (III) ) to afford phosphate backbones and DDTT was used for the preparation of phosphorothioate linkages. Aqueous ammonium was used to cleave oligos from solid support and to remove protecting groups globally. The oligonucleotide crude was then concentrated by Genevac and purified by AEX-HPLC. The pure fractions were combined and concentrated, and their purity was analyzed by LC-MS. The oligonucleotides were then dialyzed against water using MidiTrap G-25 column, concentrated, and their OD amounts were measured.
[0436] To prepare siRNA duplexes, the sense and antisense strands were annealed at 95 ℃for 10 min, based on equal molar amounts, and cooled down to room temperature. The duplex purity was determined by AEX-HPLC, and the solutions were lyophilized to afford the desired siRNA duplex powder.
[0437] In vitro Screening
[0438] The compounds were diluted into the desired concentration with PBS. The diluted compounds were then transfected into the cultured Huh7 cells with Lipofectamine RNAiMAX reagents on Day 0. Each compound was tested at two concentrations of 0.4 nM and 0.08 nM. After 24 hours incubation post transfection, RNA was extracted from the transfected cells using MNTR / FX96 (LR) kit. cDNA was generated from the isolated RNA using High-Capacity cDNA Reverse Transcription Kits with RNase Inhibitor and a TaqMan RT-qPCR gene expression assay was conducted to analyze the efficacy of each compound in silencing FXI mRNA. Data is presented as %of FXI mRNA remaining relative to mock transfection when normalized to GAPDH mRNA levels (Mean, + / -SD) .
[0439] The percentage of human FXI mRNA remaining in cells relative to mock transfection when normalized to GAPDH mRNA levels, was determined for each compound at a concentration of either 0.4 nM or 0.08 nM. The results identified several compounds that were able to reduce the level of human FXI mRNA in transfected cells by 20%to 50%or more than 50%at the defined concentrations as described in Table 2) .
[0440] In vivo HDI screening
[0441] 6-to 8-week-old female BALB / c mice were administered subcutaneously with a single dose of 0.5 mg / kg of selected siRNA compounds for one dose screening (Table 2) , or with a single dose of 0.25, 0.5, or 1 mg / kg of selected siRNA compounds for dose-response study (Table 2) . Three days later, animals were transiently transfected in vivo with FXI-expressing plasmid by hydrodynamic tail vein injection (HDI) . 24 hours post-HDI administration, animals were sacrificed, and liver tissues were isolated and stored in RNA later at 4℃. RNA in the liver were extracted using MNTR / FX96 (LR) kit (GeneOn BioTech) . cDNA was generated from the isolated RNA using High-Capacity cDNA Reverse Transcription Kits with RNase Inhibitor and a TaqMan RT-qPCR gene expression assay was conducted to analyze the compound potency in silencing FXI mRNA. Data is presented as %of FXI mRNA remaining relative to mock transfection when normalized to NeoR mRNA levels (Mean, + / -SD) . The results of the 0.5 mg / kg in vivo potency experiments are shown in Table 2. The results of the in vivo dose response experiments are shown in Table 2. The tested compounds were able to reduce the level of human FXI mRNA.

[0443] In Vitro potency in Primary Human Hepatocytes (PHH)
[0444] Additional siRNAs compounds against FXI transcript NM_000128 were designed (Table 3) and in vitro potency for selected compounds was tested in PHH cells. On Day 0, PHH were seeded into 96-well plates at the density of 54,000 cells per well. The compounds were diluted to the desired concentrations (100, 20, 4, 0.8, 0.16, 0.032, 0.0064, and 0.00128 nM) with PBS. The compounds were added at the same time of seeding cells by free uptake. After 48 hours incubation, the culture medium was removed, and the cells were harvested for RNA isolation. cDNA was generated from the isolated RNA using High-Capacity cDNA Reverse Transcription Kits with RNase Inhibitor (4374967, Thermofisher) and TaqMan RT-qPCR gene expression assay was conducted to analyze the compound potency in silencing FXI mRNA. Data is presented as %of FXI mRNA remaining relative to mock control when normalized to GAPDH mRNA levels (Mean, + / -SD) . (FIG. 1) .
[0445] In Vivo potency evaluation in Cynomolgus Monkey
[0446] To evaluate liver FXI gene knockdown and blood FXI protein suppression in non-human primates, nonterminal studies were conducted using cynomolgus monkeys. Sixteen 3-6-year-old male cynomolgus monkeys were randomly divided into four study groups based on body weight and basal serum FXI levels, with four monkeys per group. Blood samples were collected at pre-dose timepoints (Day -8, Day -4, and Day 0) to determine baseline serum FXI protein levels. Animals received a single 3 or 9 mg / kg subcutaneous dose of duplex 2 or the same volume of PBS on Day 0. Follow-up serum samples were collected on Days 7, 14, 21, 28, 35, 42, 56, 63, 70, 77 and 84 post-dose. Serum FXI protein was analyzed to determine FXI protein levels using a commercially available ELISA kit (Abcam, cat #ab108834) following the manufacturer's instructions. The maximum reduction of serum FXI was 90.6%and 97%for 3mg / kg and 9mg / kg, respectively (FIG. 2A) .
[0447] Approximately 1.8 mL of whole blood was collected from the cephalic vein of the forelimb into an anticoagulant tube containing 0.2 mL of sodium citrate (109 mmol / L) . The sample was then centrifuged at 2500 g for 10 minutes at room temperature to separate the platelet-poor plasma. For APTT assay, 50 μL of the separated plasma from cynomolgus monkey was mixed 1: 1 with a suspension containing kaolin activator (APTT reagent) and incubated at 37℃ for 240 seconds. An equal volume (to plasma) of 0.025 M calcium chloride was then added. Subsequently, the coagulation time was measured using a coagulation analyzer (FIG. 2B) .
[0448] Additional isolated oligonucleotides shown in Table 3 were investigated in Cynomolgus monkey.
[0449] To evaluate liver FXI gene knockdown and blood FXI protein suppression in non-human primates, nonterminal studies were conducted using cynomolgus monkeys. Twelve 3-5 year-old male cynomolgus monkeys were randomly divided into four study groups based on body weight and basal serum FXI levels, with three monkeys per group. A liver biopsy was performed 8 days prior to dosing (Day -8) to establish baseline FXI mRNA expression levels. Blood samples were collected at pre-dose timepoints (Day -20, Day -8, and Day 0) to determine baseline serum FXI protein levels. Animals received a single 3 mg / kg subcutaneous dose on Day 0, 8 days after the initial liver biopsy. Follow-up liver biopsies were conducted on Day 28 post-dose, while serum samples were collected on Days 7, 14, 28, 56, 70, and 84 post-dose.
[0450] Liver tissues were analyzed via RT-qPCR to assess residual FXI mRNA, and serum samples were evaluated for FXI protein levels. Liver mRNA was extracted using the RNeasy Plus Mini Kit. Reverse transcription to cDNA was performed with the High -Capacity cDNA Reverse Transcription Kit containing RNase Inhibitors. TaqMan Multiplex qPCR Assays were used to quantify relative FXI mRNA levels over time. Data are presented as the percentage of FXI mRNA remaining relative to baseline when normalized to Gapdh mRNA levels (Mean f SD) . (FIG. 3A) . Serum FXI protein was analyzed using a commercially available ELISA kit (Abcam, cat #ab108834) following the manufacturer's instructions (FIG. 3B) .
[0451] Approximately 1.8 mL of whole blood was collected from the cephalic vein of the forelimb into an anticoagulant tube containing 0.2 mL of sodium citrate (109 mmol / L) . The sample was then centrifuged at 2500 g for 10 minutes at room temperature to separate the platelet-poor plasma. For APTT assay, 50 μL of the separated plasma from cynomolgus monkey was mixed 1: 1 with a suspension containing kaolin activator (APTT reagent) and incubated at 37℃ for 240 seconds. An equal volume (to plasma) of 0.025 M calcium chloride was then added. Subsequently, the coagulation time was measured using a coagulation analyzer (FIG. 3C) .
