Abstract
Description
A PHARMACEUTICAL COMBINATION AND THE USE THEREOFTECHNICAL FIELD
[0001] The present invention relates to the pharmaceutical field, and particularly relates to a pharmaceutical combination and the use thereof.BACKGROUND OF THE INVENTION
[0002] Proliferative diseases represent a serious threat to modern society. Cancerous growths pose serious challenges for modern medicine due to their unique characteristics, including uncontrollable cell proliferation, an ability to invade local and even remote tissues, lack of differentiation, lack of detectable symptoms and lack of effective therapy and prevention. Worldwide, more than 10 million people are diagnosed with cancer every year, and cancer causes six million deaths every year or 12%of the deaths worldwide.
[0003] The embryonic ectoderm development (EED) inhibitor has been shown to be a potent anti-cancer drug, however, there is still a need to potentiate the use of the EED inhibitor further and improve the outcome of cancer treatment.
[0004] T-cell lymphoma (TCL) is a highly heterogeneous group of invasive Non-Hodgkin’s Lymphomas (NHLs) with adverse prognosis and limited treatment options. TCL comprise approximately 10-15%of all NHLs. The main subsets are peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL) .
[0005] In another aspect, T-cell malignancies are endemic in East Asia, the Caribbean, intertropical Africa, the Middle East, South America, and Papua New Guinea. However, because of the comprehensive pathogenesis and limited therapeutics, patients with T-cell lymphomas usually have a poor prognosis and are prone to relapse. Currently, chemotherapy is the most preferred treatment in T-cell lymphoma patients. With the development of chemotherapy, the prognosis of T-cell leukemia / lymphoma has gradually improved. However, due to the non-specific toxicity of current chemotherapeutic compounds to normal cells, the progressive loss of quality of life is a matter of concern.
[0006] The treatment of patients with T-cell lymphomas is challenging. Novel therapeutic strategies are urgently needed to improve the therapeutic effects of T-cell lymphomas.SUMMARY OF THE INVENTION
[0007] The inventors discovered that the pharmaceutical combination comprising an EED inhibitor and another inhibitor selected from the group consisting of a histone deacetylase (HDAC) inhibitor, a JAK inhibitor and a BCL2 / BCL-XL inhibitor produces synergistic anti-cancer effects compared with a single EED inhibitor or HDAC inhibitor.
[0008] The inventors discovered that the EED inhibitor is particularly useful for T-cell lymphoma treatment, and is more effective and potent than other therapeutics (such as Valemetostat, MAK683, and Tazemetostat) for T-cell lymphoma treatment.
[0009] In one aspect, the invention provides a pharmaceutical combination comprising an embryonic ectoderm development (EED) inhibitor and another inhibitor selected from the group consisting of a histone deacetylase (HDAC) inhibitor, a JAK inhibitor and a BCL2 / BCL-XL inhibitor.
[0010] In one aspect, the invention provides a pharmaceutical composition comprising the pharmaceutical combination disclosed herein and pharmaceutically acceptable carriers.
[0011] In one aspect, the invention provides a method for treating cancer in a subject, comprising administering a therapeutically effective amount of the pharmaceutical combination disclosed herein or the pharmaceutical composition disclosed herein to the subject.
[0012] In one aspect, the invention provides a method for treating a disease in a subject, comprising administering a therapeutically effective amount of an EED inhibitor to the subject.
[0013] In one aspect, the invention provides use of the pharmaceutical combination disclosed herein or the pharmaceutical composition disclosed herein in the manufacture of a medicament for treating cancer.
[0014] In one aspect, the invention provides use of an EED inhibitor in the manufacture of a medicament for treating a disease.
[0015] In one aspect, the invention provides the pharmaceutical combination disclosed herein or the pharmaceutical composition disclosed herein for use in treating cancer.

This kind of physical bonding involves ionization and covalent bonding (including hydrogen bonding) in different degrees. In some cases (e.g., when one or more solvent molecules are incorporated into crystal lattice of crystalline solid) , the solvate can be isolated. Thus, the solvate comprises both solution phase and isolatable solvates. The compounds of the invention may be in solvated forms with pharmaceutically acceptable solvents (such as water, methanol and ethanol) , and the present application is intended to encompass both solvated and unsolvated forms of the compounds of the invention.
[0073] One type of solvate is a hydrate. “Hydrate” relates to a specific subset of solvates wherein the solvent molecule is water. Solvates generally function in the form of pharmacological equivalents. The preparation of solvates is known in the art, see for example, M. Caira et al, J. Pharmaceut. Sci., 93 (3) : 601-611 (2004) , which describes the preparation of a solvate of fluconazole with ethyl acetate and water. Similar methods for the preparation of solvates, hemisolvates, hydrates and the like are described by van Tonder et al, AAPS Pharm. Sci. Tech., 5 (1) : Article 12 (2004) and A. L. Bingham et al, Chem. Commun. 603-604 (2001) . A representative and non-limiting method for the preparation of solvate involves dissolving a compound of the invention in a desired solvent (organic solvent, water or a mixture thereof) at a temperature above 20 ℃ to about 25 ℃, and then the solution is cooled at a rate sufficient to form a crystal, and the crystal is separated by a known method such as filtration. Analytical techniques such as infrared spectroscopy can be used to confirm the presence of the solvent in the crystal of the solvate.
[0074] The term “about” as used herein, includes the recited number ± 10%. Thus, “about 10” means 9 to 11.

[0177] Hut102, HH and H9 cell lines were treated with increasing concentrations of Compound A, Valemetostat, MAK683 or Tazemetostat alone for 6 days. Hut78 cell lines were treated with increasing concentrations of Compound A, Valemetostat, MAK683 or Tazemetostat alone for 15 days. The anti-proliferative activity was assessed by assay (CTG) in vitro, and the growth inhibition curve is depicted using GraphPad Prism 9. The cell survival percentage is represented as Mean ± SEM, and n=2 or 3.

[0183] Example 2: Synergistic anti-proliferative effect of Compound A in combination with HDAC inhibitor Tucidinostat on TCL cell lines
[0184] Materials and Methods:
[0185] The cell viability was tested using cell proliferatio experiment, as described in Example 1. In the CTG experiment, the in vitro proliferation inhibition effect of Compound A alone was tested on two commonly used T cell lymphoma cell lines Hut102 and HH.
[0186] Hut102 cell line was purchased from Cobioer (Nanjing, China) and maintained / cultured in vitro as suspension in RPMI 1640 medium (Gibco, Cat#C11875500BT) supplemented with 10%fetal bovine serum (FBS, Gibco, Grand Island, NY, USA; Cat#10099141C) , 100U / mL penicillin, 100 μg / mL streptomycin and 100 U / ml IL-2.
[0187] HH cell line was from CRL-2105TM and cultured in RPMI 1640 medium ( 30-2001TM) containing 10%fetal bovine serum, 100U / mL penicillin and 100μg / mL streptomycin.
[0188] Cells were maintained at 37℃ in an atmosphere of 5%CO2 in air and passaged twice weekly. All the cell lines were subjected to genetic identification and free of microbial contamination.
[0189] The cell lines were treated with a gradient concentration of Compound A, Tucidinostat alone or in combination, and the cell growth inhibiting activity is detected by CellTiter-Glo luminescence method. The cell survival percentage is represented as Mean ± SEM, n = 2 or 3.
[0190] Results and Conclusions:
[0191] The growth inhibition effects of Compound A in combination with HDAC inhibitor (Tucidinostat) on human TCL cell line are shown in Figures 1A and 1B.
[0192] Compound A as a single agent not only exerted anti-proliferative activity against Hut102 and HH cells, but also was outstanding that Compound A in combination with HDAC inhibitor (Tucidinostat) , exhibiting as after the combined administration, the IC50 value is reduced, and be compared by the IC50s of the combined administration curve and single drug curve, it is observed that the combined administration group curve is moved left.
[0193] The results showed that when Compound A is combined with HDAC inhibitor Tucidinostat (chidamide) , although either Compound A or Tucidinostat (chidamide) alone displayed variable antiproliferative activity, their combination consistently exerted synergistic activity in two TCL cell lines, i.e., Hut102 and HH cell lines. The curves for cell proliferation shifted to the left, indicating a synergistic activity. Further analysis showed that the combined index (CI value) was less than 0.3 at multiple combination concentrations, confirming a synergistic effect of the combination. The combination index (CI) is less than 0.9, which shows that the two-drug combination has a synergistic effect. Combination index (CI) was calculated by CalcuSyn software v2.0 (Biosoft, Cambridge, UK) , as follows: CI= (D) 1 / (Dχ) 1+ (D) 2 / (Dχ) 2
[0194] Where (Dχ) 1 and (Dχ) 2 represent the concentration of each drug alone to exertχ%effect, while (D) 1 and (D) 2 signify concentrations of the two drugs in combination to elicit the same effect. A CI value of less than 1 indicates synergism; 1, additivity; and greater than 1, antagonism. In the current combination study, cellular proliferative data were further analyzed with CI < 0.1 labeled as 5+ for a very strong synergistic effect; CI between 0.1 and 0.3 labeled as 4+ for a strong synergistic effect; and CI between 0.3 and 0.9 labeled as 3+ for a medium synergistic effect.
[0195] The combination, in which Compound A has different concentrations from that of Tucidinostat (chidamide) , was also tested in different cell lines (e.g., Hut102 and HH cell lines) and also showed a synergistic effect.
[0196] Example 3: Synergistic anti-proliferative effect of Compound A in combination with JAK1 inhibitor Golidocitinib on TCL cell lines
[0197] Materials and Methods:
[0198] Cell viability was assessed using the Luminescent Cell Viability Assay, as described in Example 1. In this assay, the in vitro proliferation inhibitory effect of Compound A in combination with the JAK1 inhibitor Golidocitinib was evaluated on the HuT102 T cell lymphoma cell line.
[0199] The HuT102 cell line was obtained from Cobioer (Nanjing, China) and cultured as a suspension in RPMI 1640 medium ( 30-2001TM) , supplemented with 10%fetal bovine serum (FBS, Gibco, Grand Island, NY, USA; Cat#10099141C) , 100 U / mL penicillin, 100 μg / mL streptomycin, and 100 U / mL IL-2 (Peprotech, Cat#200-02) . Cells were maintained at 37℃ in a humidified atmosphere with 5%CO2 and passaged twice weekly. All cell lines were genetically authenticated and confirmed to be free of microbial contamination.
[0200] HuT102 cells were treated with indicated gradient concentrations of Compound A for 6 days, Golidocitinib for 3 days, or their combination. The inhibitory effect on cell growth was determined using the luminescent assay. Cell viability data were represented as Mean ± SD, with n =2 replicates.
[0201] Results and Conclusions:
[0202] The growth inhibitory effects of Compound A in combination with the JAK1 inhibitor Golidocitinib on the HuT102 cell line are shown in Figure 2.
[0203] Compound A, as a single agent, demonstrated significant antiproliferative activity against HuT102 cells. Notably, the antiproliferative activity against the HuT102 cells was enhanced when Compound A was combined with golidocitinib. the curves for cell proliferation shifted to the left, indicating an enhanced and / or synergistic activity. Further analysis indicated that the combination index (CI) values calculated using CalcuSyn software were all less than 0.3 at multiple combination concentrations, indicating strong synergistic inhibitory effects. The CI values were calculated using CalcuSyn software v2.0 (Biosoft, Cambridge, UK) , as described in Example 2. A CI value of less than 0.9 further supports the synergistic effect of the drug combination. Our study provides a scientific rationale for the future clinical development of Compound A and golidocitinib in treating TCL patients.
[0204] Example 4: Synergistic anti-proliferative effect of Compound A in combination with JAK1 inhibitor Golidocitinib on NK / TCL cell lines
[0205] Materials and Methods:
[0206] Cell viability was assessed using the Luminescent Cell Viability Assay, as described in Example 1. In this assay, the in vitro proliferation inhibition effect of Compound A in combination with the JAK1 inhibitor Golidocitinib was evaluated on two commonly used NK / T cell lymphoma cell lines, SNK-1 and SNK-6.
[0207] The SNK-1 cell line was cultured as a suspension in RPMI 1640 medium ( 30-2001TM) supplemented with 10%human serum AB (GeminiBio, Cat#100-318) , 100 U / mL penicillin, 100 μg / mL streptomycin, and 100 U / mL IL-2 (Peprotech, Cat#200-02) . The SNK-6 cell line was cultured under similar conditions in RPMI 1640 medium ( 30-2001TM) with the same supplements. Both cell lines were maintained at 37℃ in a humidified atmosphere of 5%CO2 and passaged twice weekly. All cell lines were genetically authenticated and confirmed to be free of microbial contamination.
[0208] Cells were treated with a gradient concentration of Compound A for 10 days and Golidocitinib for 2 days. The inhibitory effect on cell growth was determined using the luminescent assay. Cell viability data were represented as Mean ± SEM, with n = 2 or 3 replicates.
[0209] Results and Conclusions:
[0210] The growth inhibitory effects of Compound A in combination with the JAK1 inhibitor Golidocitinib on human NK / T cell lymphoma (NK / TCL) cell lines are shown in Figures 3A and 3B. As a single agent, Compound A demonstrated significant antiproliferative activity against both SNK-1 and SNK-6 cells. Notably, the combination of Compound A with Golidocitinib further enhanced this antiproliferative activity. A leftward shift of concentration effect curves for combinations when compared to single agent curves indicates synergism,
[0211] The results showed that when Compound A is combined with JAK1 inhibitor (Golidocitinib) , although either Compound A or Golidocitinib alone exerted limited antiproliferative activity in two NK / TCL cell lines, i.e., SNK-1 and SNK-6, However, their combination consistently exerted synergistic activity in NK / TCL cell lines. The curves for cell proliferation shifted to the left, indicating a synergistic activity. Further analysis showed that the combined index (CI value) was less than 0.3 at multiple combination concentrations, indicating moderate (CI score 3+) to very strong (CI score 5+) synergistic inhibitory effects. The combination index (CI) is less than 0.9, which shows that the two-drug combination has a synergistic effect. Combination index (CI) was calculated by CalcuSyn software v2.0 (Biosoft, Cambridge, UK) .
[0212] These findings provide a scientific rationale for the future clinical development of Compound A and Golidocitinib in treating NK / TCL patients.
[0213] Example5: Synergistic anti-proliferative effect of Compound A in combination with BCL2 / BCL-XL inhibitor Compound B on NK / TCL cell lines
[0214] Materials and Methods:
[0215] Cell viability was assessed using the Luminescent Cell Viability Assay, as described in Example 1. In this assay, the in vitro proliferation inhibition effect of Compound A in combination with the BCL2 / BCL-XL inhibitor Compound B was evaluated on two commonly used NK / T cell lymphoma cell lines, SNK-1 and SNK-6.
[0216] The SNK-1 cell line was maintained in vitro as a suspension in RPMI 1640 medium ( 30-2001TM) supplemented with 10%human serum AB (GeminiBio, Cat#100-318) , 100 U / mL penicillin, 100 μg / mL streptomycin, and 100 U / mL IL-2 (Peprotech, Cat#200-02) . The SNK-6 cell line was cultured under the same conditions in RPMI 1640 medium ( 30-2001TM) with the same supplements. Both cell lines were maintained at 37℃ in a humidified atmosphere of 5%CO2 and passaged twice weekly. All cell lines were genetically authenticated and confirmed to be free of microbial contamination.
[0217] Cells were treated with a gradient concentration of Compound A for 10 days and Compound B for 2 days. The inhibitory effect on cell growth was determined using the luminescent assay. Cell viability data were represented as Mean ± SD, with n = 2 or 3 replicates.
[0218] Results and Conclusions:
[0219] The growth inhibitory effects of Compound A in combination with the BCL2 / BCL-XL inhibitor Compound B on human NK / T cell lymphoma (NK / TCL) cell lines are shown in Figures 4A and 4B. As a single agent, Compound A or Compound B alone demonstrated antiproliferative activity against both SNK-1 and SNK-6 cells. Notably, the combination of Compound A with Compound B further enhanced this antiproliferative activity, as evidenced by the leftward shift of the combination treatment curves compared to the single-agent curves.
[0220] The results showed that when Compound A was combined with Compound B, although either agent alone displayed variable antiproliferative activity, their combination consistently exerted synergistic effects in both NK / TCL cell lines (SNK-1 and SNK-6) . The leftward shift in the proliferation curves indicates this synergistic activity. Further analysis revealed that the combination index (CI) values, calculated using CalcuSyn software v2.0 (Biosoft, Cambridge, UK) , were less than 0.3 at multiple combination concentrations, confirming strong synergistic inhibitory effects. A CI value of less than 0.9 further supports the synergistic interaction between the two drugs.
