Description

PHARMACEUTICAL COMPOSITION FOR USE IN THE THERAPEUTIC TREATMENT OF CANCER AND COMPLICATIONS OF CANCER
[Technical Field ofthe Invention]
The présent invention relates to a pharmaceutical composition that can be used as a médicament, particularly for the therapeutic treatment of cancers, and specifically of hepatocellular carcinoma.
[Prior Art]
Effective palliative treatment for hepatocellular carcinoma (HCC) has long been considered difficult, because this type of tumor tends to be résistant to conventional cytotoxic chemotherapy. Moreover, aggressive chemotherapy with several non15 sélective cytotoxic molécules often cannot be offered to cirrhotic patients with compromised liver function due to the high risk of systemic side effects.
Improved knowledge of the molecular processes involved in oncogenesis has led to .· - the identification of new targets for the treatment of-cancers. New so-called targeted 20 ’.utherapies are thus currently available in the treatment· pf HGC and other tumors. They intervene mainly in the transduction of signais (signais that ask the cell to multiply). The so-called tyrosine kinase pathway is the best known to date. This pathway can be blocked by monoclonal antibodies (Mabs) or enzymatic inhibitors (inib). These drugs include VEGF inhibitors (vascular endothélial growth factor; VEGF is secreted by most 25 tumor cells, partly due to lack of local oxygénation, and promûtes angiogenesis), EGFR (Epidermal Growth Factor Receptor) inhibitors, inhibitors of several receptors with tyrosine kinase activity that simultaneously target angiogenesis and cell prolifération, kinase inhibitors, IGF-IR inhibitors, mTOR inhibitors, and MEK-ERK signaling pathway inhibitors.
For the most part, however, these targeted thérapies yield relatively modest results in terms of efficiency and survival in HCC and especially in advanced HCC. What is more, the effectiveness of targeted thérapies for HCC is still limited by résistance phenomena. Some cancer cells possess or acquire the ability to circumvent the mechanisms of action of médicaments, while others are sensitive at first but develop résistance capabilities over the course of treatment.
It should also be hoted that significant side effects associated with these targeted thérapies can cause discomfort, thereby denying patients a better quality of life: myelosuppression (blood tests are performed regularly to check red blood cells, white blood cells and platelets), alopecia (which can be psychologically difficult for patients to deal with because it is a concrète and visible sign ofthe disease), skin disorders and hand-foot syndrome, diarrhea, increased blood pressure, proteinuria, hyperglycemia, hypercholesterolemia, allergie reactions, cytokine release syndrome, tumor lysis syndrome that can self-sustain the tumor, etc.
ln addition, several observations point to the existence of a close link between chronic inflammation and the risk of developing cancer. One of the best examples of this corrélation is undoubterfly .the dramatic (20-fold) increase in the risk of colon cancer in people with inflammatory.bowel disease, particularly ulcerative colitis. This al^o-applies to stomach cancer, which develops after an inflammation caused by the presence of a bacterium, Hélicobacter .pylori. Prostate cancer is caused by inflammation >of the prostate (prostatitis). ln CHC, the hypothesis is that chronic inflammation increases DNA mutations and that increased prolifération of hépatocytes in régénération nodules increases the likelihood of attachment of oncogenic mutations. Furthermore, pre- and post-infusion médication that combines a corticosteroid and an antihistamine is strongly recommended in order to reduce the risk of allergie reactions associated with certain targeted thérapies.
While biomàrkers hâve been validated for breast cancer (number of copies of HER), {A 3 .
lung cancer (EGFR mdtations), or colon cancer (Kras mutations), there are currently no validated.pronostic biomarkers for HCC under targeted therapy.
Λ A ; ·
A number of studies hâve shown that reptin and/or pontine are overexpressed during carcinogenesis; their nudeocytoplasmic localization varied depending on the type of cancer and was not nectssarify a factor of poor prognosis. On the other hand, the overexpression of reptin and pôntine is a factor of poor prognosis in HCC, and a high level of pontine mRNA is correiated with a poor prognosis [(Haurie et al., 2009). Hepatology. 2009 Dec;50(6): 1871-83. doi: f0.1002/hep.23215].
·. , ·.
In additioh, it is known that reptin is bverexpréssed in prostate cancer, hepatoœllular carcinoma (HCC), gast'ic cancer, kidnèÿ Cancer, and breast cancer.
It is also known that pontine is overexpressed in hepatocellular carcinoma, lung cancer, 15 and colorectal cancer. i '.. '
The dysfunction of reptin and / or pontine had also been demonstrated in other cancers such as chronic leukemias, raésotheliom'as, hnd multiple myelomas, high-grade • · r· . lymphomas,Burkitt lymphomas, brain tumoFs such as gliomas, and bladder tumors.

Survivin is also known as a therapeutic target in the case of cancer. The majority of solid tumors (cancer ofthe breast, pros'ate, kmg, kidney, etc.) or hematopoietic tumors (multiple myeloma, leukemia, etc.) express it in an aberrant manner. It is also known ' that cancercus breast, lung, and kidney tumor cells'overexpress survivin.
Moreover, it is known that beta-elemene can be used as an anticancer drug. What is more, it has a broad antineoplastic spectrum, including tumors that are résistant to the anticancer drugs that are conventionally used. it is also known to be non-cytotoxic and well tolerated by patients. It is able to pass through the blood-brain barrier and has 30 immunostimulatory properties. Its anti-inflammatory activity is also known. It is also known that beta-elemene inhibits survivin. It is also known to reduce or even suppress the résistance of cancer cells to anticancer drugs.
It is also known that beta-elemene also reduces the résistance of cancer cells to certain drugs. For instance, it has a substantial inhîbitory effect on MDR1, MRP, and GST-n. Chen et al., (2006) (Journal of Médicinal Plants Research Vol. 6 (46), pp. 5720-5729, 3 December 2012) hâve shown that 13-elemene inevitably increases the intracellular accumulation of AMD in 11251/AMD cells (cells that hâve developed a résistance to AMD) ofthe human glioblastoma and reduces the IC50 of U251/AMD cells from 0.915 to 0.051 mg/l.
In addition, it is also known that lupeol (also known as Fagarasterol or Clerodol), is a pharmacologically active compound with anti-inflammatory, anticancer properties, particularly due to its antiproliférative activity, its régulation of the cell cycle, of apoptosis, and of angiogenesis, and its effect on the epithelial-mesenchymal transition. It also stimulâtes the immune system of cancer patients. It should be noted that, at the effective therapéutic dose, lupeol exhibits no toxicity to normal cells and tissues.
In the case of-CHC, lupeol is known to inhibit the Brain-Derived Neurotrophic Factor (BDNF). Lupegt inhibits cell prolifération of HCCLM3 cells of HC.G..as. a fonction of concentration and time through activation of Caspase-3 and cleâvage of PARP [poly(ADP-ribose)polymerase]. However, Zhang L. et al. (Européen Journal of Pharmacology, volume 762, 5 September 2015, pages 55-62) also found that the lupeol-induced death of these cells was associated with a marked decréase in the expression of the BDNF protein and ser-9-phosphorylation of GSK-313 (Glycogen Synthase Kinase 3 Beta), with concomitant suppression of the expression of Akt1, PBK (phosphatidylinositol 3-kinase), 13-catenin, c-Myc, and mRNA of cyclin D1. The inhibition of the overexpression of BDNF is therefore a resuit of the decrease in the expression of the Akt and PI3k proteins as weli as the réactivation of the GSK-313 fonction.
What is more, oral administration of lupéol at a dose of 50 mg/kg for 18 consecutive days produced neither mortality nor systemic toxicity in rats.
It is also known that the cinnamaldéhydes - particularly cinnamaldéhyde (CA), 2hydroxycinnamaldehyde (HCA), and 2-benzoyloxycinnamaldehyde (BCA), a semisynthetic dérivative of HCA - each hâve anti-inflammatory, antiproliférative, antiangiogenic, antimetastatic activity due to the inhibition of the TEM (epithelialmesenchymal transition) and proapoptotic activity on many human cancer cells such as melanoma, breast cancer, lung cancer, ovarian cancer, colon cancer, prostate cancer, myeloma, and leukemia.
In a model mouse that developed
Η-rasl 2V mutation and under the it was found that administration of
It is also known that HCA has an effect on HCC. Thus, Moon E.Y. (Eun-Yi Moon et al., (2005) European Journal of Pharmacology 530 (2006) 270-275) investigated the inhibitory effect of HCA on farnesyltransferase, hepatocellular carcinoma following a transgenic control of a. spécifie promoter such as albumin,
HCA/BCA for 10 weeks delayed the development of liver cancer compared to the control group. HCA/BCA significantly,reduces the frequency and extent of liver damage. HCA/BCA increases the-.yrujmber of splénocytes and infiltration of lymphocytes in the liver. These data suggest that delayed onset of liver cancer may be caused by an immunostimulatory effect of HCA/BCA on T cells.
Moreover, beta-sitosterol is known to ’possess anti-inflammatory, antipyretic, antineoplastic, and immunomodulatory properties.

Different human Hep3B (hepatocellular carcinoma), MCF-7 (breast cancer), DU-145 (prostate cancer) cell lines were studied. They were selected on the basis of their ability ' to overexpress at least one protein from among reptin, pontin, and survivin. The stromal cells were also studied in order to détermine the impact of the composition according to the invention in the tumor microenvironment. These cells were maintained in DMEM and supplemented with 10% fêtai bovine sérum (FBS) and 1% antibioticantimycotic solution (MSP) containing penicillin, streptomycin, and amphotericin B under standard growth conditions (5% CO2, 37 °C, humïdified atmosphère). The compositions above were dissolved and diluted in DMSO.
The cells above were treated with increasing solutions for 72 h in complété cell media. Ail treatment and control protocols were prepared as described previously.
In monotherapy, lupeol and 2-hydroxycinnamaldehyde were observed to hâve a more pronounced antiproliférative effect on the three lines, including Hep3B, DU-145, and MCF-7, compared to β-elemene after 72 hours of exposure.
Solutions combining the molécules hâve been studied, including lupeol-p-elemene, 2hydroxycinnamaldehyde-P-elemene, and 2-hydroxycinnamaldehyde-lupeol. After 72 hours of exposure, an additive and synergistic effect of the higher 2hydroxycinnamaldehyde-lupeol combination was observed on Hep3B, DU 145, and MCF-7 cell lines compared to the other combinations.

The effect of this combination on the induction of Hep3B cell apoptosis was determined . using annexin V/propidium iodide after 48 hours of treatment. Increased staining of annexin-V was observed in Hep3B cells, whereas minimal staining was observed in uritreated control cells.
In a co-culture of cancerous and stromal cells, treatment of confluent (50% confluent) cells with any of the prepared solutions resulted in decreased adhesion associated with cancer cell death, inhibition of stromal ceii production of soluble factors found in the tumor microenvironment and involved in the metastatic process and in 30 chemoresistance.
These results as a whole suggest that this pharmaceutical composition inhibits tumor stromal formation and hence metastatic dissémination and chemoresistance. It can be rightfully used in the treatment of hepatocellular carcinoma, breast cancer, and 5 prostate cancer - even in advanced stages.
