Description

Technical Field

[0001] The present invention relates to the field of biopharmaceuticals and therapeutic agents composed of nucleic acid-based molecules. More particularly, the present invention relates to compounds and compositions that utilize RNA interference (RNAi) to modulate the expression of human GST-π and their use.

[0002] This application includes a sequence listing that was electronically submitted as an ASCII file created on December 20, 2015, named ND5123385WO_SL.txt, which is 100,000 bytes in size, and the entire sequence listing is incorporated herein by reference.

Background Art

[0003] It has been found that various human cancer tissues correlate with the emergence of the mutant KRAS gene. In some cases, the tissue also shows an increase in the expression level of glutathione S-transferase Pi (GST-π) (Miyanishi et al., Gastroenterology, 2001, Vol. 121:865-874, abstract). For example, an increase in serum GST-π levels was observed in patients with various gastrointestinal malignancies (Niitsu et al., Cancer, 1989, Vol.63, No.2, pp.317-323, abstract).

[0004] GST-π is a member of the GST family of enzymes that play a role in detoxification by catalyzing the conjugation of hydrophobic compounds with electrophilic compounds having reduced glutathione. GST-π expression can be decreased by siRNA in vitro (Niitsu et al., US 2014 / 0315975 A1). However, existing siRNA agents have many drawbacks, such as insufficient activity, off-target effects, lack of serum stability, and lack of in vivo efficacy or effect.

[0117] RNA interference RNA interference (RNAi) refers to sequence-specific post-transcriptional gene silencing in animals mediated by short interfering RNAs (siRNAs). See, for example, Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Fire et al., Nature, 1998, Vol. 391, pp. 806-811; Sharp, Genes & Development, 1999, Vol. 13, pp. 139-141.

[0118] The RNAi response within cells can be induced by double-stranded RNA (dsRNA), but the mechanism is not yet fully understood. Certain dsRNAs within cells can be acted upon by the Dicer enzyme, a ribonuclease III enzyme. See, e.g., Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Hammond et al., Nature, 2000, Vol. 404, pp. 293-296. Dicer can process dsRNA into shorter fragments of dsRNA known as siRNA.

[0119] Generally, siRNA can be about 21 to about 23 nucleotides in length and can include a base pair duplex region about 19 nucleotides in length.

[0120] RNAi is involved in an endonuclease complex known as the RNA-induced silencing complex (RISC). siRNA has an antisense or guide strand that enters the RISC complex and mediates 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 occurs in the middle of the region complementary to the antisense strand of the siRNA duplex (see, e.g., Elbashir et al., Genes & Development, 2001, Vol. 15, pp. 188-200).

[0121] As used herein, the term "sense strand" refers to the nucleotide sequence of an siRNA molecule that is partially or completely complementary to at least a portion of the corresponding antisense strand of the siRNA molecule. The sense strand of an siRNA molecule can include a nucleic acid sequence having homology to the target nucleic acid sequence.

[0122] As used herein, the term "antisense strand" refers to the nucleotide sequence of an siRNA molecule that is partially or completely complementary to at least a portion of the target nucleic acid sequence. The antisense strand of an siRNA molecule can include a nucleic acid sequence complementary to at least a portion of the corresponding sense strand of the siRNA molecule.

[0123] RNAi molecules can down-regulate or knockdown gene expression by mediating RNA interference in a sequence-specific manner. See, for example, Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Elbashir et al., Nature, 2001, Vol. 411, pp. 494-498; Kreutzer et al., WO2000 / 044895; Zernicka-Goetz et al., WO2001 / 36646; Fire et al., WO1999 / 032619; Plaetinck et al., WO2000 / 01846; Mello et al., WO2001 / 029058.

[0124] As used herein, the terms “inhibit,” “down-regulate,” or “reduce” with respect to gene expression mean that the expression of a gene or the level of an mRNA molecule encoding one or more proteins, or the activity of one or more of the encoded proteins, is lower than the activity observed in the absence of the RNAi molecule or siRNA of the present invention. For example, the level of expression, the level of mRNA, or the level of encoded protein activity may be reduced by at least 1%, or at least 10%, or at least 20%, or at least 50%, or at least 90%, or more, compared to the activity observed in the absence of the RNAi molecule or siRNA of the present invention.

[0125] RNAi molecules can also be used to knockdown viral gene expression, thus affecting viral replication.

[0126] RNAi molecules can be made from separate polynucleotide strands: a sense strand or passenger strand, and an antisense strand or guide strand. The guide strand and the passenger strand are at least partially complementary. The guide strand and the passenger strand can form a double-stranded region having from about 15 to about 49 base pairs.

[0127] In some embodiments, the double-stranded region of the siRNA can comprise 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, or 49 base pairs.

[0128] In certain embodiments, the RNAi molecule can be active in the RISC complex and have a length of the double-stranded region that is active against RISC.

[0129] In a further embodiment, the RNAi molecule can be active as a Dicer substrate that is converted into an RNAi molecule that is active in the RISC complex.

[0130] In some aspects, the RNAi molecule can have a guide and a passenger sequence portion that are complementary to opposing ends of a long molecule, such that the molecule can form a double-stranded region in the complementary sequence portion, and each strand is joined at one end of the double-stranded region by either a nucleotide or a non-nucleotide linker. For example, a hairpin sequence stem and loop sequence. The interaction between each strand and the linker can be a covalent or non-covalent interaction.

[0131] The RNAi molecules of the present disclosure may include a nucleotide, non-nucleotide, or nucleotide / non-nucleotide mixed linker that binds the sense region of the nucleic acid to the antisense region of the nucleic acid. The nucleotide linker can be a linker having a length of 2 nucleotides or more, for example, about 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides. The nucleotide linker may also be a nucleic acid aptamer. As used herein, "aptamer" or "nucleic acid aptamer" means a nucleic acid molecule that specifically binds to a target molecule, where the nucleic acid molecule has a sequence that includes a sequence recognized by the target molecule in its natural context. Alternatively, the aptamer may be a nucleic acid molecule that binds to a target molecule, where the target molecule does not have to bind to the nucleic acid naturally. For example, an aptamer can bind to the ligand-binding domain of a protein and can be used to prevent the interaction between a naturally occurring ligand and the protein. See, for example, Gold et al., Annu Rev Biochem, 1995, Vol. 64, pp. 763-797; Brody et al., J. Biotechnol., 2000, Vol. 74, pp. 5-13; Hermann et al., Science, 2000, Vol. 287, pp. 820-825.

[0132] Examples of non-nucleotide linkers include abasic nucleotides, polyethers, polyamines, polyamides, peptides, carbohydrates, lipids, polyhydrocarbons or other polymeric compounds, such as polymeric compounds having 2 to 100 ethylene glycol units, such as polyethylene glycol. Some examples are described in Seela et al., Nucleic Acids Research, 1987, Vol. 15, pp. 3113-3129; Cload et al., J. Am. Chem. Soc., 1991, Vol. 113, pp. 6324-6326; Jaeschke et al., Tetrahedron Lett., 1993, Vol. 34, p. 301; Arnold et al., WO1989 / 002439; Usman et al., WO1995 / 006731; Dudycz et al., WO1995 / 011910; and Ferentz et al., J. Am. Chem. Soc., 1991, Vol. 113, pp. 4000-4002.

[0133] The RNAi molecule can have one or more overhangs from the double-stranded region. An overhang is a single-stranded region that is not base-paired and may be 1 to 8 nucleotides or more in length. The overhang may be a 3'-end overhang having a single-stranded region of 1 to 8 nucleotides at the 3'-end of the strand. The overhang may be a 5'-end overhang having a single-stranded region of 1 to 8 nucleotides at the 5'-end of the strand.

[0134] The overhangs of the RNAi molecule may have the same length or different lengths.

[0135] The RNAi molecule can have one or more blunt ends where the double-stranded region ends without an overhang and the strands base pair to the end of the double-stranded region.

[0136] The RNAi molecules of the present disclosure can have one or more blunt ends, or can have one or more overhangs, or can have a combination of blunt ends and overhangs.

[0137] The 5' end of the strand of the RNAi molecule may be a blunt end or may have an overhang. The 3' end of the strand of the RNAi molecule may be a blunt end or may have an overhang.

[0138] The 5' end of the strand of the RNAi molecule may be a blunt end and the 3' end may have an overhang. The 3' end of the strand of the RNAi molecule may be a blunt end and the 5' end may have an overhang.

[0139] In some embodiments, both ends of the RNAi molecule are blunt ends.

[0140] In further embodiments, both ends of the RNAi molecule have overhangs.

[0141] The 5'- and 3'-terminal overhangs may be of different lengths.

[0142] In certain embodiments, the RNAi molecule may have blunt ends where the 5' end of the antisense strand and the 3' end of the sense strand do not have overhang nucleotides.

[0143] In further embodiments, the RNAi molecule may have blunt ends where the 3' end of the antisense strand and the 5' end of the sense strand do not have overhang nucleotides.

[0144] The RNAi molecule may have mismatches in base pairing in the double-stranded region.

[0145] Any nucleotide in the overhang of the RNAi molecule can be a deoxyribonucleotide or a ribonucleotide.

[0146] One or more deoxyribonucleotides may be present at the 5' end, where the 3' end of the other strand of the RNAi molecule may not have an overhang and may not have a deoxyribonucleotide overhang.

[0147] One or more deoxyribonucleotides may be present at the 3'-end, where the 5'-end of the other strand of the RNAi molecule may not have an overhang and may not have a deoxyribonucleotide overhang.

[0148] In some embodiments, one or all of the overhang nucleotides of the RNAi molecule may be 2'-deoxyribonucleotides.

[0149] Dicer substrate RNAi molecules In some aspects, the RNAi molecule can be of a length suitable as a Dicer substrate that is processed to produce a RISC-active RNAi molecule. See, e.g., Rossi et al., US2005 / 0244858.

[0150] The double-stranded RNA (dsRNA) that is a Dicer substrate can be of a length sufficient to be processed by Dicer to produce an active RNAi molecule and may further include one or more of the following characteristics: (i) the Dicer substrate dsRNA can be asymmetric, e.g., having a 3'-overhang on the antisense strand, and (ii) the Dicer substrate dsRNA may have a modified 3'-end on the sense strand that directs the orientation of Dicer binding and processes the dsRNA into an active RNAi molecule.

[0151] In certain embodiments, the longest strand in the Dicer substrate dsRNA can be 24 to 30 nucleotides in length.

[0152] The Dicer substrate dsRNA can be symmetric or asymmetric.

[0153] In some embodiments, the Dicer substrate dsRNA can have a sense strand of 22 to 28 nucleotides and an antisense strand of 24 to 30 nucleotides.

[0154] In certain embodiments, the dicer substrate dsRNA may have an overhang at the 3' end of the antisense strand.

[0155] In further embodiments, the dicer substrate dsRNA can have a sense strand that is 25 nucleotides in length and an antisense strand that is 27 nucleotides in length including a 2-base 3'-overhang. The overhang can be 1, 2, or 3 nucleotides in length. The sense strand may also have a 5' phosphate.

[0156] The asymmetric dicer substrate dsRNA can have two deoxyribonucleotides at the 3' end of the sense strand instead of two ribonucleotides.

[0157] The sense strand of the dicer substrate dsRNA can be about 22 to about 30, or about 22 to about 28, or about 24 to about 30, or about 25 to about 30, or about 26 to about 30, or about 26 and 29, or about 27 to about 28 nucleotides in length.

[0158] The sense strand of the dicer substrate dsRNA can be 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleotides in length.

[0159] In certain embodiments, the dicer substrate dsRNA may have sense and antisense strands that are at least about 25 nucleotides in length and do not exceed about 30 nucleotides in length.

[0160] In certain embodiments, the dicer substrate dsRNA may have sense and antisense strands that are 26 to 29 nucleotides in length.

[0161] In certain embodiments, the dicer substrate dsRNA may have a sense strand and an antisense strand that are 27 nucleotides in length.

[0162] The sense and antisense strands of the dicer substrate dsRNA can have blunt ends and be of the same length, or can be of different lengths with overhangs, or can have blunt ends and protrusions.

[0163] The dicer substrate dsRNA may have a double-stranded region 19, 20, 21, 22, 23, 24, 25, 26, or 27 nucleotides in length.

[0164] The antisense strand of the dicer substrate dsRNA can have any sequence that anneals to at least a part of the sequence of the sense strand under biological conditions such as in the cytoplasm of eukaryotic cells.

[0165] The dicer substrate having a sense strand and an antisense strand can be linked by a third structure such as a linker group or a linker oligonucleotide. The linker can, for example, link the two strands of the dsRNA and form a hairpin upon annealing.

[0166] The sense and antisense strands of the dicer substrate are generally complementary, but may have mismatches in base pairing.

[0167] In some embodiments, the dicer substrate dsRNA may be asymmetric such that the sense strand has 22-28 nucleotides and the antisense strand has 24-30 nucleotides.

[0168] One of the strands of the dicer substrate dsRNA, particularly the region of the antisense strand, may have a sequence length of at least 19 nucleotides, and these nucleotides are within a 21-base region adjacent to the 3' end of the antisense strand and are sufficiently complementary to the nucleotide sequence of the RNA produced from the target gene.

[0169] The antisense strand of the dicer substrate dsRNA can have 1 to 9 ribonucleotides at the 5' end so that its length is 22 to 28 nucleotides. When the length of the antisense strand is 21 nucleotides, 1 to 7 ribonucleotides, or 2 to 5 ribonucleotides, or 4 ribonucleotides can be added to the 3' end. The added ribonucleotides can have any sequence.

[0170] The sense strand of the dicer substrate dsRNA may have 24 to 30 nucleotides. The sense strand may be substantially complementary to the antisense strand and anneal to the antisense strand under biological conditions.

[0171] Methods of using RNAi molecules The nucleic acid molecules and RNAi molecules of the present invention can be delivered to cells or tissues by direct application of the molecules or by using molecules combined with a carrier or diluent.

[0182] Exemplary protocol for in vitro knockdown One day before transfection, 100 μl of DMEM (HyClone catalog number SH30243.01) containing 10% FBS was seeded into a 96-well plate at 2×10 3 cells / well and cultured in an incubator at 37 °C with a humidified atmosphere in 5% CO2 air. Before transfection, the medium was changed to 90 μl of Opti-MEM I reduced serum medium (Life Technologies catalog number 31985-070) containing 2% FBS. Then, 0.2 μl of Lipofectamine RNAiMax (Life Technologies catalog number 13778-100) was mixed with 4.8 μl of Opti-MEM I at room temperature for 5 minutes. Next, 1 μl of siRNA was mixed with 4 μl of Opti-MEM I, mixed with the LF2000 solution, and gently mixed without vortexing. After 5 minutes at room temperature, the mixture was incubated at room temperature for an additional 10 minutes to form the RNA-RNAiMax complex. Furthermore, 10 μl of the RNA-RNAiMax complex was added to the well and the plate was gently shaken by hand. The cells were incubated in an incubator at 37 °C with a humidified atmosphere in 5% CO2 air for 2 hours. The medium was replaced with fresh Opti-MEM I reduced serum medium containing 2% FBS. Twenty-four hours after transfection, the cells were washed once with ice-cold PBS. The cells were lysed with 50 μl of Cell-to-Ct lysis buffer (Life Technologies catalog number 4391851C) for 5 - 30 minutes at room temperature. 5 μl of stop solution was added and incubated for 2 minutes at room temperature. The mRNA level was immediately measured by RT-qPCR using TAQMAN. The samples could be frozen at -80 °C and assayed later.

[0183] Exemplary protocol for serum stability 0.2 mg / ml of siRNA was incubated with 10% human serum at 37°C. At specific time points (0, 5, 15, and 30 minutes), 200 μl of the sample was aliquoted and extracted with 200 μl of an extraction solvent (chloroform:phenol:isoamyl alcohol = 24:25:1). The sample was vortexed and centrifuged at 13,000 rpm for 10 minutes at room temperature, and then the upper layer solution was transferred and filtered through a 0.45 μm filter. The filtrate was transferred to a 300 μl HPLC injection vial. For LCMS, the mobile phases were MPA: 100 mM HFIP + 7 mM TEA in H2O, and MPB: 50% methanol + 50% acetonitrile. Column: Waters Acquity OST 2.1×50 mm, 1.7 μm was used.

[0227] As shown in Table 14, the activity of GST-π siRNA based on Structure B13’ having three 2'-F deoxynucleotides at non-overhang positions was surprisingly increased by about 3-fold compared to GST-π siRNA having no 2'-F deoxynucleotides.

[0228] These data indicate that GST-π siRNA having a structure with one or more 2'-F deoxynucleotides has unexpectedly high gene knockdown activity compared to GST-π siRNA having no 2'-F deoxynucleotides.

[0229] The activities shown in Table 14 for GST-π siRNA having one or more 2'-F deoxynucleotides were in the picomolar range of 6 pM and were very suitable for many applications including drug agents used in vivo.

[0230] Example 9: Orthotopic A549 lung cancer mouse model. The GST-π siRNA of the present invention can show a significant reduction of orthotopic lung tumors in vivo. In this example, GST-π siRNA brought about gene knockdown efficacy in vivo when administered in a liposomal formulation to orthotopic lung tumors of athymic nude mice.

[0231] Generally, orthotopic tumor models can show direct clinical relevance with respect to drug efficacy and potency, as well as improved predictive ability. In an orthotopic tumor model, tumor cells are directly transplanted into the same organ from which the cells are derived.

[0232] The antitumor efficacy of the siRNA formulation against human lung cancer A549 was evaluated by comparing the final primary tumor weights measured at autopsy in the treatment group and the vehicle control group.

[0233] Figure 1 shows the in vivo orthotopic lung tumor inhibition of GST-π siRNA based on structure BU2 (SEQ ID NOs: 61 and 126). An orthotopic A549 lung cancer mouse model was used at a relatively low dose of 2 mg / kg of siRNA targeting GST-π.

[0234] GST-π siRNA showed significant and unexpectedly favorable lung tumor inhibition efficacy in this 6-week study. As shown in Figure 1, after 43 days, GST-π siRNA showed significantly favorable tumor inhibition efficacy, and the final tumor average weight was significantly reduced by 2.8-fold compared to the control.

[0235] For this study, male NCr nu / nu mice at 5 - 6 weeks of age were used. During the experimental period, the experimental animals were maintained in a HEPA - filtered environment. The siRNA formulation was stored at 4°C before use and warmed to room temperature 10 minutes before injection into the mice.

[0236] On the day of surgical orthotopic implantation (SOI), for this A549 human lung cancer orthotopic model, the stock tumor was harvested from the subcutaneous site of animals with A549 tumor xenografts and placed in RPMI - 1640 medium. Necrotic tissue was removed, and the viable tissue was cut into pieces of 1.5 - 2 mm 3 in length. The animals were anesthetized by isoflurane inhalation, and the surgical area was sterilized with iodine and alcohol. A transverse incision of approximately 1.5 cm was made on the left chest wall of the mice using a pair of surgical scissors. An intercostal incision was made between the third and fourth ribs to expose the left lung. One A549 tumor fragment was transplanted onto the surface of the lung with 8 - 0 surgical sutures (nylon). The chest wall was closed with 6 - 0 surgical sutures (silk). The lung was re - inflated by intra - thoracic puncture using a 3 cc syringe with a 25G×1 / 2 needle to draw out the remaining air in the thoracic cavity. The chest wall was closed with 6 - 0 surgical silk sutures. All procedures of the above operations were performed using a 7 - fold magnifying microscope under a HEPA - filtered laminar flow hood.

[0237] Three days after tumor transplantation, the tumor - bearing model mice were randomly divided into groups of 10 mice per group. For the target group, the treatment of 10 mice was started three days after tumor transplantation.

[0238] For the target group, the formulation was a liposomal composition of (ionizable lipid:cholesterol:DOPE:DOPC:DPPE - PEG - 2K:DSPE - PEG - 2K). The liposomes encapsulated GST - π siRNA.

[0239] Regarding the test endpoint, the experimental mice were sacrificed 42 days after the start of treatment. The primary tumors were excised and weighed on an electronic balance for subsequent analysis.

[0240] Regarding the evaluation of the toxicity of the compound, the average body weights of the mice in the treatment group and the control group were maintained within the normal range throughout the experimental period. No other symptoms of toxicity were observed in the mice.

[0241] Example 10: The GST-π siRNA of the present invention showed a significant reduction in cancer xenograft tumors in vivo. The GST-π siRNA brought about a gene knockdown effect in vivo when administered to cancer xenograft tumors in a liposomal formulation.

[0242] Figure 2 shows the tumor inhibitory efficacy of GST-π siRNA (SEQ ID NOs: 156 and 182). A cancer xenograft model was used at a relatively low dose of 0.75 mg / kg of siRNA targeting GST-π.

[0243] The GST-π siRNA showed a significant and unexpectedly favorable tumor inhibitory efficacy within several days after administration. After 36 days, the GST-π siRNA showed a significantly favorable tumor inhibitory efficacy, and the tumor volume decreased by 2-fold compared to the control.

[0244] As shown in Figure 3, the GST-π siRNA showed a significant and unexpectedly favorable tumor inhibitory efficacy on the last day. In particular, the tumor weight decreased by more than 2-fold.

[0245] The GST-π siRNA was administered as a liposomal formulation having a composition (ionizable lipid:cholesterol:DOPE:DOPC:DPPE-PEG-2K) (25:30:20:20:5) by two injections (on day 1 and day 15).

[0246] For the cancer xenograft model, the A549 cell line was obtained from ATCC. The cells were maintained in a culture medium supplemented with 10% fetal bovine serum, 100 U / ml penicillin, and 100 μg / ml streptomycin. The cells were split 48 hours before inoculation to be in the logarithmic growth phase at the time of harvest. The cells were gently trypsinized with trypsin-EDTA and recovered from tissue culture. The number of viable cells was counted and measured with a hemocytometer in the presence of trypan blue (only viable cells were counted). The cells were resuspended in serum-free medium at 5×107 It was resuspended at a concentration of / ml. Subsequently, the cell suspension was thoroughly mixed with ice-thawed BD Matrigel at a ratio of 1:1 and used for injection.

[0247] The mice were Charles River Laboratory's thymic nude mice (nu / nu) female mice, immunodeficient, 6 - 8 weeks old, with 7 - 8 mice per group.

[0248] For tumor model preparation, using a 25G needle and syringe per mouse for one inoculation dose, 0.1 ml of an inoculum of 2.5×10 6 A549 cells were subcutaneously inoculated into the right flank. The mice were not anesthetized for inoculation.

[0249] For tumor volume measurement and randomization, the tumor size was measured to the nearest 0.1 mm. The tumor volume was calculated using the formula: tumor volume = length × width 2 / 2. When the established tumors reached approximately 120 - 175 mm 3 the average tumor volume was approximately 150 mm 3 and the mice were assigned to various vehicle control and treatment groups so that the average tumor volume of the treatment group was within 10% of the average tumor volume of the vehicle control group. Ideally, the CV% of the tumor volume was less than 25%. On the same day, the test article and control vehicle were administered according to the dosing regimen. The tumor volume was monitored 3 times in the first week and 2 times in the remaining weeks including the end of the study.

[0250] For drug administration, on the administration day, the test article was taken out from the -80°C freezer and thawed on ice. Before applying to the syringe, the bottle containing the formulation was hand - inverted several times. All test articles were administered IV at 0.75 mg / kg, q2wX2, at 10 ml / kg.

[0251] Regarding body weight, the mice were weighed to the nearest 0.1 g. The body weight was monitored and recorded daily within 7 days of the first administration. In the remaining weeks including the end of the study, the body weight was monitored for several weeks and recorded twice a week.

[0252] To collect tumors 28 days after the initial dosing, tumor volumes were measured, tumors were dissected for weighing, and stored for PD biomarker studies. Tumor weights were recorded.

[0253] Example 11: The GST-π siRNA of the present invention showed an increase in cancer cell death by apoptosis of cancer cells in vitro. GST-π siRNA brought about GST-π knockdown, resulting in upregulation of PUMA, a biomarker of apoptosis, along with a decrease in cell viability.

[0254] The GST-π siRNA SEQ ID NOs: 156 and 182, which contain a combination of deoxynucleotides, 2'-F-substituted deoxynucleotides, and 2'-OMe-substituted ribonucleotides in the seed region, unexpectedly increased apoptosis of cancer cells.

[0255] The expression levels of PUMA for GST-π siRNA SEQ ID NOs: 156 and 182 are shown in Figure 4. As shown in Figure 4, the expression of PUMA increased significantly 2 - 4 days after transfection with GST-π siRNA.

[0256] These data indicate that the structure of GST-π siRNA containing a combination of deoxynucleotides, 2'-F-substituted deoxynucleotides, and 2'-OMe-substituted ribonucleotides in the seed region unexpectedly increases apoptosis of cancer cells.

[0257] The protocol for the PUMA biomarker was as follows. One day before transfection, 100 μl of DMEM (HyClone catalog number SH30243.01) containing 10% FBS was added to a 96-well plate at 2×10 3Cells were seeded in wells and cultured in a 37°C incubator with a humidified atmosphere in 5% CO2 air. The next day, prior to transfection, the medium was exchanged with 90 μl of Opti-MEM I reduced serum medium (Life Technologies catalog number 31985-070) containing 2% FBS. Then, 0.2 μl of Lipofectamine RNAiMAX (Life Technologies catalog number 13778-100) was mixed with 4.8 μl of Opti-MEM I at room temperature for 5 minutes. 1 μl of siRNA (stock concentration 1 μM) was mixed with 4 μl of Opti-MEM I, mixed with the RNAiMAX solution, and then gently mixed. The mixture was incubated at room temperature for 10 minutes to form an RNA-RNAiMAX complex. 10 μl of the RNA-RNAiMAX complex was added per well to give a final siRNA concentration of 10 nM. The cells were incubated for 2 hours and the medium was exchanged with fresh Opti-MEM I reduced serum medium containing 2% FBS. At 1, 2, 3, 4 and 6 days after transfection, the cells were washed once with ice-cold PBS and then lysed at room temperature for approximately 5 - 30 minutes using 50 μl of Cell-to-Ct lysis buffer (Life Technologies catalog number 4391851C). 5 μl of stop solution was added and incubated at room temperature for 2 minutes. The mRNA level of PUMA (BBC3, Cat#Hs00248075, Life Technologies) was measured by qPCR using TAQMAN.

[0258] Example 12: The GST-π siRNA of the present invention was able to show a significant reduction in cancer xenograft tumors in vivo. The GST-π siRNA can provide gene knockdown efficacy in vivo when administered to cancer xenograft tumors in a liposomal formulation.

[0259] Figure 5 shows the tumor inhibitory efficacy of GST-π siRNA (SEQ ID NOs: 61 and 126). Dose-dependent knockdown of GST-π mRNA was observed in vivo with siRNA targeting GST-π. A cancer xenograft model was used with a relatively low dose of 0.75 mg / kg of siRNA targeting GST-π.

[0260] GST-π siRNA showed significant and unexpectedly favorable tumor inhibitory efficacy within several days after administration. As shown in Figure 5, treatment with GST-π siRNA significantly decreased GST-π mRNA expression 4 days after injection into the lipid formulation. At a high dose of 4 mg / kg, a significant decrease of about 40% was detected 24 hours after injection.

[0261] GST-π siRNA was administered as a single injection as a 10 mL / kg liposomal formulation with a composition (ionizable lipid:cholesterol:DOPE:DOPC:DPPE-PEG-2K) (25:30:20:20:5).

[0262] For the cancer xenograft model, the A549 cell line was obtained from ATCC. The cells were maintained in RPMI-1640 supplemented with 10% fetal bovine serum, 100 U / ml penicillin, and 100 μg / ml streptomycin. The cells were split 48 hours before inoculation to be in the logarithmic growth phase at the time of harvest. The cells were gently trypsinized with trypsin-EDTA and harvested from tissue culture. The number of viable cells was counted and measured with a hemocytometer in the presence of trypan blue (counting only viable cells). The cells were resuspended in serum-free RPMI medium at a concentration of 4×10 7 / ml. The cell suspension was then thoroughly mixed with ice-thawed BD Matrigel at a 1:1 ratio and used for injection.

[0263] The mice were Charles River Laboratory thymic nude (nu / nu) female mice, immunodeficient, 6 - 8 weeks old, with 3 mice per group.

[0264] For tumor model preparation, 0.1 ml of an inoculum of 2×10 6 A549 cells was subcutaneously inoculated into the right flank of each mouse using a 25G needle and syringe per inoculum dose. The mice were not anesthetized for inoculation.

[0265] For tumor volume measurement and randomization, tumor size was measured to the nearest 0.1 mm. Tumor volume was calculated using the formula: Tumor volume = length × width 2 / 2. Tumor volume was monitored twice a week. When the established tumor reached approximately 350 - 600 mm 3 the mice were assigned to groups at various time points. On the same day, the test article was administered according to the dosing regimen.

[0266] For drug administration, on the day when the established tumor reached approximately 350 - 600 mm 3 the test article was removed from the refrigerator at 4°C. Before applying to the syringe, the bottle containing the formulation was inverted by hand several times to make a homogeneous solution.

[0267] For body weight, the mice were weighed to the nearest 0.1 g. Body weight was monitored for several weeks including the end day of the study and recorded twice a week.

[0268] For tumor collection, the animals were sacrificed with excess CO2 and the tumors were dissected at 0, 24, 48, 72, and 96 (optional) and 168 hours after administration. The tumors were first moistened and divided into three parts for KD, distribution, and biomarker analysis. The samples were snap-frozen in liquid nitrogen and stored at -80°C until ready to be processed.

[0269] Example 13: The GST-π siRNA of the present invention inhibited pancreatic cancer xenograft tumors in vivo. The GST-π siRNA produced gene knockdown efficacy in vivo when administered to pancreatic cancer xenograft tumors in a liposomal formulation.

[0270] In this xenograft model, each mouse was subcutaneously inoculated in the right flank with 0.1 ml of a 2.5×10 6 PANC-1 cell inoculum. Thymus-deficient nude female mice (6 - 8 weeks old, Charles River) were used. Tumor size was measured to the nearest 0.1 mm. When the established tumor reached approximately 150 - 250 mm 3 (average tumor volume approximately 200 mm 3) When it reached, the mice were assigned to various vehicle controls and treatment groups such that the average tumor volume in the treatment group was within 10% of the average tumor volume in the vehicle control group. On the same day, the test article and the control vehicle were administered according to the dosing regimen. Tumor volume was monitored 3 times in the first week and 2 times in the remaining weeks including the end of the study.

[0271] Figure 6 shows the tumor inhibitory efficacy of GST-π siRNA (SEQ ID NOs: 63 and 128). As shown in Figure 6, the dose response was obtained at doses in the range of 0.375 mg / kg to 3 mg / kg of siRNA targeting GST-π. GST-π siRNA showed significant and unexpectedly favorable tumor inhibitory efficacy within several days after administration. Therefore, GST-π siRNA showed significant and unexpectedly favorable tumor inhibitory efficacy at the endpoint.

[0272] GST-π siRNA was administered in a liposomal formulation having a composition (ionizable lipid:cholesterol:DOPE:DOPC:DPPE-PEG-2K) (25:30:20:20:5).

[0273] Example 14: The GST-π siRNA of the present invention showed increased serum stability.

[0274] Figure 7 shows the incubation in human serum and the detection of the remaining siRNA at various time points by HPLS / LCMS. As shown in Figure 7, the half-life (t 1 / 2 ) in serum of both the sense strand (Figure 7, upper panel) and the antisense strand (Figure 7, lower panel) of GST-π siRNA (SEQ ID NOs: 61 and 126) was approximately 100 minutes.

[0275] Example 15: The GST-π siRNA of the present invention showed improved stability in the formulation in plasma.

[0276] Figure 8 shows the incubation of the formulation in plasma and the detection of the remaining siRNA at various time points. As shown in Figure 8, the plasma half-life (t 1 / 2) was significantly longer than 100 hours.

[0277] GST-π siRNA was prepared in a liposomal formulation having the composition (ionizable lipid:cholesterol:DOPE:DOPC:DPPE-PEG-2K) (25:30:20:20:5). The z-average size of the liposomal nanoparticles was 40.0 nm and the siRNA was 91% encapsulated.

[0278] The formulation was incubated in 50% human serum in PBS for 40 minutes, 1.5 hours, 3 hours, 24 hours, and 96 hours. The amount of GST-π siRNA was determined by an ELISA-based assay.

[0279] Example 16: The GST-π siRNA of the present invention showed a reduced off-target effect by the passenger strand.

[0280] For GST-π siRNA (SEQ ID NOs: 156 and 182), Figure 9 shows that the in vitro knockdown for the guide strand was almost exponential compared to a control having a scrambled sequence that showed no effect. The IC50 of this siRNA was measured at 5 pM. Figure 10 shows the in vitro knockdown of the passenger strand of the same GST-π siRNA. As shown in Figure 10, the off-target knockdown of the passenger strand for GST-π siRNA was reduced by more than 100-fold.

[0281] For GST-π siRNA (SEQ ID NOs: 187 and 199), (SEQ ID NOs: 189 and 201), and (SEQ ID NOs: 190 and 202), Figure 11 shows that the in vitro knockdown of the guide strand was approximately exponential. The IC50 of these siRNAs was measured at 6, 7, and 5 pM, respectively. As shown in Figure 12, the in vitro knockdown of the passenger strand of these GST-π siRNAs was significantly reduced by at least 10-fold. All of these GST-π siRNAs had deoxynucleotides in the seed region of the duplex region and no other modifications in the duplex region.

[0282] For GST-π siRNA (SEQ ID NOs: 217 and 232), FIG. 13 shows that the in vitro knockdown of the guide strand of this highly active GST-π siRNA was almost exponential. The IC50 of this siRNA was measured at 11 pM. As shown in FIG. 14, the in vitro knockdown of the passenger strand of this GST-π siRNA decreased significantly by more than 100-fold. This GST-π siRNA had deoxynucleotides in the seed region of the double-stranded region, and there were no other modifications in the double-stranded region.

[0283] The off-target effect was determined using the expression reporter plasmid psiCHECK-2 encoding the Renilla luciferase gene (Dual-Luciferase Reporter Assay System, Promega, Catalog No.: E1960). The siRNA concentration was typically 50 pM. Protocol: On day 1, HeLa cells were seeded at 5 - 7.5×10 3 / 100 μl / well. On day 2, co-transfection was performed at approximately 80% cell confluence. On day 3, the cells were harvested and luciferase activity was measured. Luciferase activity was measured using the Promega luciferase assay system (E4550) according to the manufacturer's protocol.

[0284] The psiCHECK-2 vector can monitor changes in the expression of the target gene fused to the reporter gene of Renilla luciferase. The siRNA construct was cloned into the multiple cloning region, and the vector was co-transfected into HeLa cells with the siRNA. When a specific siRNA binds to the target mRNA and initiates the RNAi process, the fusion Renilla luciferase:construct mRNA is cleaved and subsequently degraded, reducing the Renilla luciferase signal.

[0285] For example, the plasmid insert for siRNA having the BU2' structure was as follows: PsiCHECK-2 (F) plasmid insert: Accession number 285 ctcgag gggcaacTGAAGCCTTTTGAGACCCTGcTgTcccag gcggccgc PsiCHECK-2 (R) plasmid insert: Accession number 286 ctcgag cTgggacagCAGGGTCTCAAAAGGCTTCagTTgccc gcggccgc

[0286] Example 17: The GST-π siRNA of the present invention was shown to have a significantly reduced miRNA-like off-target effect, which is seed-dependent unintended off-target gene silencing.

[0287] For GST-π siRNAs (SEQ ID NOs: 156 and 182), (SEQ ID NOs: 187 and 199), (SEQ ID NOs: 189 and 201), (SEQ ID NOs: 190 and 202), and (SEQ ID NOs: 217 and 232), the off-target activity mimicking miRNA was found to be essentially negligible. The seed-dependent unintended off-target gene silencing of these GST-π siRNAs was at least 10- to 100-fold less than the target activity of the guide strand.

[0288] To test the miRNA-related off-target effect, seed-complementary target sequences with 1 to 4 repeats that are complementary to the entire seed-containing region at positions 1 to 8 at the 5'-end of the antisense strand but not to the remaining non-seed region (positions 9 to 21) were introduced into the region corresponding to the 3'UTR of luciferase mRNA to determine the efficiency of the seed-dependent unintended off-target effect. Using plasmid inserts, miRNAs with perfect matching in the seed region and mismatches (bulges) in the non-seed region were mimicked.

[0289] For example, the plasmid insert for the siRNA having the BU2' structure was as follows: PsiCHECK-2 (Fmi1) plasmid insert: Accession number 287 ctcgag gggcaacTCTACGCAAAACAGACCCTGcTgTcccag gcggccgc PsiCHECK-2 (Fmi2) plasmid insert: SEQ ID NO: 288 ctcgag gggcaacTCTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT gTcccag gcggccgc PsiCHECK-2 (Fmi3) plasmid insert: SEQ ID NO: 289 ctcgag gggcaacTCTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT gTcccag gcggccgc PsiCHECK-2 (Fmi4) plasmid insert: SEQ ID NO: 290 ctcgag gggcaacTCTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT CTACGCAAAACAGACCCTGcT gTcccag gcggccgc
