Definitions

  • the present invention relates to the field of treating cancer.
  • the pre sent disclosure relates to a combination treatment for cancer as well as composi tions to be used in the treatment of cancer.
  • Multi-clonal tumors are major setbacks to moleclarly-targeted therapies (which only inhibit subsets of certain tumor clones that host the druggable oncogenic targets), thus rendering other competing tumor subclones (with undruggable oncogenic tar gets) resistant to such treatments.
  • tumor stem cells exhibit stem like properties with limited proliferation particularly upon exposure to treatment yet retain self-renewal capacity (cancer stem cells or CSCs) which could result in tumor relapse.
  • CSCs could also migrate to distant organs and form distant metastatic tumors with more diverse tumor sub clones, particularly under increased selective pressures of survival, thus certain emerging subclones will develop increased resistance to chemotherapy and mo- lecular targeted therapy which will further progress to aggressive tumor retard sion, worse prognosis and poor survival.
  • chemotherapy leads to poor quality of life due to well- documented side effects, including cancer cachexia (muscle wasting and loss of appetite), associated with high pro-inflammatory TNF-alpha levels, chemotherapy induced alopecia due to non-specific targeting of high proliferative cells, fatigue and physical (including bone cancer pain) and neurological pain through IL-6-TRPA1 and TNF-alpha-TRPA1 pathways (Liu et al., 2019).
  • IL-6-TRPA1 and TNF-alpha-TRPA1 pathways Liu et al., 2019.
  • Blocking IL-6 and TNF-alpha was shown to be beneficial in inhibiting pain in in-vivo models including chemotherapy-induced pain.
  • autoimmune-like im mune related adverse events commonly arises in patients.
  • Persistence in T-cell responses, through in-hibiting T-cell exhaustion (via ICIs) could prolong the expression of inflammatory cytokines and could trigger self-antigen presentation alongside tumor antigen presentation; thus, targeting both tumor and surrounding inflamed target organ or tissue (Konig & Laubli, 2020).
  • Post-mortem studies show ed that melanoma cancer patients receiving ICIs led to immune infiltration in the myocardial tissue which developed into myocarditis (GOrdogan, 2020).
  • IL-6 is also known to be a surrogate of immune response, inflammation, tumor progression and pain. Serum IL-6 is associated with worse prognosis and poor sur vival in cancer patients.
  • iRAEs such severe arthri-tis, myocarditis, uveitis, gre at vasculitis, severe pneumonia, great vasculitis, and myasthenia gravis
  • Tocili- Kursab Anti IL-6 Receptor antibody
  • Targeting IL-6 pathway does not activate tumor progression.
  • tumor cell killing without over-expression of IL-6 and/or activate IL-6 sig nalling pathways and other inflammatory cytokines pose as great benefit for pati ents such as inhibit-ing cancer cachexia, physical and neuropathic pain and fatigue- thus contributing towards improving quality of life.
  • This invention presents the combination of Ginsenoside and Mebendazole to trigger im-mune-mediated tumor cell killing without the secretion of IL-6. Therefore, Ginse noside and Mebendazole combination reduces cytokine release commonly associa ted with cancer cachexia, physical and neuropathic pain, fa-tigue and poor quality of life.
  • Ginsenoside a bioactive saponin compound found in Panax ginseng in trace amounts, poses anti-proliferative and pro-apoptotic effects in tumors. Ginsenoside contributes to both extrinsic apoptosis (via Death receptors such as FAS and TRAIL) and intrinsic mitochondrial apoptosis, resulting in caspase 8 and caspase 3/7 activation downstream.
  • activated caspase 8 could also indirectly activate caspase 3/7 by trun cating BID, a pro-apoptotic protein, into its functional form tBID; tBID then contribu tes to translocating BAX to the mitochondria to re-lease mitochondrial cytochrome c thus triggering intrinsic apoptosis as well.
  • Tumors generally live in harsh pathophysiolog ical conditions such as low glucose and hypoxia which trigger intracellular ER stress and impairment in protein folding, lipid metabolism and calcium level regula tion.
  • Ginsenoside increases ER stress towards which expressing death receptors such as DR4 and DR5 receptors in tumors via PERK-ATF4-CHOP pathway; this primes cancer cells for extrinsic apoptosis upon interaction with cells that strongly express TRAIL (ligand) particularly, activated T cells and monocytes (Lam et al. , 2020; Martin-Perez et al., 2011).
  • TRAIL ligand
  • Akt also phosphorylates BAX at Serine 184 residue (S184) which causes BAX to inhibit apoptosis.
  • Ginsenosides inhibit Akt-pathway and disrupt plasma membrane lipid rafts (sphingolipid and cholesterol enriched micro domains of transmembrane proteins found clustered together which serve as external components of cell sig nalling pathways). This inactivates the pro-surivival Akt pathway and helps to ra pidly and strongly translocate BAX into the mitochondria, thus further triggering mi tochondrial-based intrinsic apoptosis.
  • Mebendazole an anti-helminth drug, ad-dresses the three strategies above by (i) phosphorylating and deactivating BCL-2 protein, (ii) enhance T-cell activation through increased clustering and interaction between CD14+monocytes/macrophages and T-cells and (iii) re-polarize immuno suppressive tumor-promoting M2 macrophages to M1 classically activated anti tumor macrophages which can directly kill the tumor and provide chemokine sig nals to increase immune infiltration of activated immune cells expressing TRAIL could interact with TRAIL-sensitized tumor cells to induce cancer cell death.
  • the tumor cell death is based on extrinsic death receptor-based and intrinsic mitochondrial-based apoptotic pathways, sug-gestively through direct interaction of death ligands in activated immune cells and death receptors in tumor cells; where ginsenosides up-regulate death receptors in stressed malnourished or hypoxic cells (such as tumor cells), while mebendazole enhances T-cell activation and limits intracellular anti-apoptotic proteins in cancer cells.
  • This provides a strategy to selectively target different malignant cells of different tissue origins while keeping physiologically unstressed cells in-tact and non- targeted, particularly hair follicles of cancer patients.
  • MDA-MB-231 Breast cancer cell line (BRAF mutant, CDKN2A mutant, K-RAS mu tant, TP53 mutant)
  • HCT-116 Colon cancer cell line K-RAS mutant, PIK3CA mutant
  • PANC-1 Pancreatic cancer cell line K-RAS mutant, TP53 mutant, CDKN2A mu tant
  • HepG2 Liver cancer cell line (CTNNB1 mutant, TERT mutant, NRAS mutant)
  • liver diseases can be categorised into: (i) viral hepatitis, (ii) genetic, (iii) drug or toxins-related, (iv) autoimmune disorders, (v) fatty liver disease and (vi) cancer. Although originated by different aetiologies all will lead, if untreated, to the formation of chronic liver fibrosis/cirrhosis which will ultimately affect the microana- tomy and function of the liver.
  • fibrosis and its latest stage, cirrhosis affects and alters the quantity and quality of ECM, specifically collagen, leading to the for mation of scar tissue (Williams).
  • Myofibroblasts are the source of ECM overproduc tion during the development of fibrosis (Lim). Myofibroblasts are not found in a nor mal, healthy liver and their origin is hepatic stellate cells (Kisseleva). Additionally, inflammation and autophagy occur during hepatic fibrosis development. Chronic inflammation in liver is an immune response that persists for months leading to tis sue remodelling, and repair processes. Regardless of aetiology, chronic liver in flammation induces hepatic fibrosis that eventually leads to cirrhosis and hepatocel lular carcinoma which is a leading cause of death worldwide (Dhar et al.).
  • the pivotal event in preventing the progression of hepatic fibrosis is to reduce the activation and transition of hepatic stellate cells into myofibroblasts or to promote hepatic stellate cells’ senescence and apoptosis (Higashi et al.).
  • Activated hepatic stellate cells cause strong cell proliferation and dramatic changes in their stellate morphology, and are accompanied by lipid deposition, degradation imbalance of extracellular matrix, and over-secretion of specific marker protein, such as alpha- smooth muscle actin (a-SMA) (Schinagl et al.).
  • hepatic stellate cells migrate with the infiltrating leukocytes into damaged area of the liver (Yagai et al.), whereas inflammatory cells evoke hepatic inflammation (Wan et al.) and secret proinflammatory, as well as profibrotic factors, including transforming growth factor b1 (TGF-bI) (Zhan et al.).
  • TGF-bI transforming growth factor b1
  • Mebendazole which is an antimicrotubular agent that possesses a high affinity for tubulin, has been shown to exert an inhibitory effect on collagen bio synthesis and secretion in cell cultures (Soto et al.). These changes were reflected in an intracellular accumulation of total proteins and collagen in fibroblasts and re sult in a marked decrease of its deposit in the extracellular matrix (Soto et al.), therefore this can be directly related to hepatic stellate cells in liver disease.
  • Anoth er study in pancreatic cancer have shown a reduced connective tissue deposition and reduced a-SMA expression in samples treated with Mebendazole in compari son to untreated samples (Williamson et al.).
  • Mebendazole has the ability to reduce the levels of TGF- b1 , which is known to stimulate fibrogenesis (Guerini et al.).
  • mebendazole has also been proven to induce cytokine release from PBMC cultures. Stimulated PBMCs released several pro-inflammatory cytokines including TNFa, IL1 b, IFNy, IL6 from PBMCs activated by IL2 and anti-CD3 stimula tion (Rubin et al.). Our studies have also demonstrated that mebendazole en hanced the secretion of IL6, TNFa and IFNy ( Figures 4, 5 and 6) which is known to promote inflammation and in the long term can enhance fibrosis.
  • our strategy is to perform a combination therapy of mebendazole with Ginsenosides, as we have demonstrated that Ginsenoside has a very significant impact on the reduction of secretion of negatively impacting inflam matory cytokines, especially when high and prolonged doses are necessary.
  • fibrotic patients can benefit from Ginsenoside as it has been demon strated that it can attenuate hepatic fibrosis through regulating autophagy process es (Liu et al.).
  • Another study has demonstrated ginsenosides ability to inhibit the T ⁇ RbI/BMA ⁇ pathway, thereby improving liver fibrosis (Hafez et al.).
  • ginsenoside can induce the apoptosis of activated hepatic stellate cells (Wu et al.).

Description

COMBINATION TREATMENT OF A SAPONIN AGENT AND AN ANTHELMINITIC AGENT
AGAINST CANCER
The present invention relates to the field of treating cancer. In particular, the pre sent disclosure relates to a combination treatment for cancer as well as composi tions to be used in the treatment of cancer.
Many attempts to treat malignant neoplastic cells through conventional therapies have been met with limited success due to inter- and intra-tumor heterogeneity within the mosaic of tumor subclones.
Multi-clonal tumors are major setbacks to moleclarly-targeted therapies (which only inhibit subsets of certain tumor clones that host the druggable oncogenic targets), thus rendering other competing tumor subclones (with undruggable oncogenic tar gets) resistant to such treatments.
Moreover, some tumor cells exhibit stem like properties with limited proliferation particularly upon exposure to treatment yet retain self-renewal capacity (cancer stem cells or CSCs) which could result in tumor relapse. CSCs could also migrate to distant organs and form distant metastatic tumors with more diverse tumor sub clones, particularly under increased selective pressures of survival, thus certain emerging subclones will develop increased resistance to chemotherapy and mo- lecular targeted therapy which will further progress to aggressive tumor progres sion, worse prognosis and poor survival.
From a patient point of view, chemotherapy leads to poor quality of life due to well- documented side effects, including cancer cachexia (muscle wasting and loss of appetite), associated with high pro-inflammatory TNF-alpha levels, chemotherapy induced alopecia due to non-specific targeting of high proliferative cells, fatigue and physical (including bone cancer pain) and neurological pain through IL-6-TRPA1 and TNF-alpha-TRPA1 pathways (Liu et al., 2019). Blocking IL-6 and TNF-alpha was shown to be beneficial in inhibiting pain in in-vivo models including chemotherapy-induced pain.
Thus, of great interest, was the paradigm shift towards antigen-independent im- muno-oncology for cancer treatment to concurrently target different subclones of the heterogenous tumor mosaic simultaneously.
However, despite efforts of non-antigen specific immune-oncology (particularly im mune checkpoint inhibitors ICIs) showing promise in achieving partial and even some complete responses in can-cer patients, a high risk of autoimmune-like im mune related adverse events (iRAEs) commonly arises in patients. Persistence in T-cell responses, through in-hibiting T-cell exhaustion (via ICIs) could prolong the expression of inflammatory cytokines and could trigger self-antigen presentation alongside tumor antigen presentation; thus, targeting both tumor and surrounding inflamed target organ or tissue (Konig & Laubli, 2020). Post-mortem studies show ed that melanoma cancer patients receiving ICIs led to immune infiltration in the myocardial tissue which developed into myocarditis (GOrdogan, 2020).
Among the most common inflammatory cytokines as biomarkers of iRAEs is IL-6 which is also known to be a surrogate of immune response, inflammation, tumor progression and pain. Serum IL-6 is associated with worse prognosis and poor sur vival in cancer patients. Among the first treatments of iRAEs such severe arthri-tis, myocarditis, uveitis, gre at vasculitis, severe pneumonia, great vasculitis, and myasthenia gravis is Tocili- zumab (Anti IL-6 Receptor antibody) which inhibits IL-6 signalling. Targeting IL-6 pathway does not activate tumor progression.
Therefore, tumor cell killing without over-expression of IL-6 and/or activate IL-6 sig nalling pathways and other inflammatory cytokines pose as great benefit for pati ents such as inhibit-ing cancer cachexia, physical and neuropathic pain and fatigue- thus contributing towards improving quality of life.
This invention presents the combination of Ginsenoside and Mebendazole to trigger im-mune-mediated tumor cell killing without the secretion of IL-6. Therefore, Ginse noside and Mebendazole combination reduces cytokine release commonly associa ted with cancer cachexia, physical and neuropathic pain, fa-tigue and poor quality of life.
Ginsenoside, a bioactive saponin compound found in Panax ginseng in trace amounts, poses anti-proliferative and pro-apoptotic effects in tumors. Ginsenoside contributes to both extrinsic apoptosis (via Death receptors such as FAS and TRAIL) and intrinsic mitochondrial apoptosis, resulting in caspase 8 and caspase 3/7 activation downstream.
Additionally, activated caspase 8 could also indirectly activate caspase 3/7 by trun cating BID, a pro-apoptotic protein, into its functional form tBID; tBID then contribu tes to translocating BAX to the mitochondria to re-lease mitochondrial cytochrome c thus triggering intrinsic apoptosis as well.
With respect to extrinsic apoptosis, Tumors generally live in harsh pathophysiolog ical conditions such as low glucose and hypoxia which trigger intracellular ER stress and impairment in protein folding, lipid metabolism and calcium level regula tion. Ginsenoside increases ER stress towards which expressing death receptors such as DR4 and DR5 receptors in tumors via PERK-ATF4-CHOP pathway; this primes cancer cells for extrinsic apoptosis upon interaction with cells that strongly express TRAIL (ligand) particularly, activated T cells and monocytes (Lam et al. , 2020; Martin-Perez et al., 2011).
However, there are several TRAIL-resistant cancer cells which are due to increased pro-survival anti-apoptotic proteins. Nevertheless, these resistant cells are sen sitized to apoptosis upon inhibition of the pro-survival Akt- pathway (commonly ex pressed in many tumors) inhibition resulting in a de-crease of pro-survival proteins (such as Bcl-2 and BcL-xL) compared to pro-apototic counterparts (BAX).
Akt also phosphorylates BAX at Serine 184 residue (S184) which causes BAX to inhibit apoptosis. Ginsenosides inhibit Akt-pathway and disrupt plasma membrane lipid rafts (sphingolipid and cholesterol enriched micro domains of transmembrane proteins found clustered together which serve as external components of cell sig nalling pathways). This inactivates the pro-surivival Akt pathway and helps to ra pidly and strongly translocate BAX into the mitochondria, thus further triggering mi tochondrial-based intrinsic apoptosis.
To further sensitise TRAIL apoptosis, three strategies could be approached: (i) By further decreasing pro-survival proteins in tumors through further inhibition of pro survival proteins (ii) By increasing TRAIL- ligand expression in cells surrounding tumors, by enhancing immune activation (iii) Convert non-immunological 'cold' tu mors to immune-infiltrative hot tumors.
Mebendazole, an anti-helminth drug, ad-dresses the three strategies above by (i) phosphorylating and deactivating BCL-2 protein, (ii) enhance T-cell activation through increased clustering and interaction between CD14+monocytes/macrophages and T-cells and (iii) re-polarize immuno suppressive tumor-promoting M2 macrophages to M1 classically activated anti tumor macrophages which can directly kill the tumor and provide chemokine sig nals to increase immune infiltration of activated immune cells expressing TRAIL could interact with TRAIL-sensitized tumor cells to induce cancer cell death. Hence in summary, the tumor cell death is based on extrinsic death receptor-based and intrinsic mitochondrial-based apoptotic pathways, sug-gestively through direct interaction of death ligands in activated immune cells and death receptors in tumor cells; where ginsenosides up-regulate death receptors in stressed malnourished or hypoxic cells (such as tumor cells), while mebendazole enhances T-cell activation and limits intracellular anti-apoptotic proteins in cancer cells.
Rather than system ically targeting highly proliferative cells which results in off-target toxicities, such as chemotherapy-induced alopecia, selective tumor cell killing ba sed upon cross-sectional ER stress-based apoptotic pathways among different tu mors.
This provides a strategy to selectively target different malignant cells of different tissue origins while keeping physiologically unstressed cells in-tact and non- targeted, particularly hair follicles of cancer patients.
Our studies also incorporate immune mediated tumor cell killing in cancer cell lines that harbor other very common oncogenic mutations such as:
A549 Lung cancer cell line (CDKN2A mutant, K-RAS mutant)
MDA-MB-231 Breast cancer cell line (BRAF mutant, CDKN2A mutant, K-RAS mu tant, TP53 mutant)
HCT-116 Colon cancer cell line (K-RAS mutant, PIK3CA mutant)
PANC-1 Pancreatic cancer cell line (K-RAS mutant, TP53 mutant, CDKN2A mu tant)
HepG2 Liver cancer cell line (CTNNB1 mutant, TERT mutant, NRAS mutant)
Additionally, the same concept described above can be utalised for liver disease. In other words, the same plausible meachnism of action may be employed for treating Never dieses. Liver diseases can be categorised into: (i) viral hepatitis, (ii) genetic, (iii) drug or toxins-related, (iv) autoimmune disorders, (v) fatty liver disease and (vi) cancer. Although originated by different aetiologies all will lead, if untreated, to the formation of chronic liver fibrosis/cirrhosis which will ultimately affect the microana- tomy and function of the liver. Both fibrosis and its latest stage, cirrhosis, affects and alters the quantity and quality of ECM, specifically collagen, leading to the for mation of scar tissue (Williams). Myofibroblasts are the source of ECM overproduc tion during the development of fibrosis (Lim). Myofibroblasts are not found in a nor mal, healthy liver and their origin is hepatic stellate cells (Kisseleva). Additionally, inflammation and autophagy occur during hepatic fibrosis development. Chronic inflammation in liver is an immune response that persists for months leading to tis sue remodelling, and repair processes. Regardless of aetiology, chronic liver in flammation induces hepatic fibrosis that eventually leads to cirrhosis and hepatocel lular carcinoma which is a leading cause of death worldwide (Dhar et al.).
The pivotal event in preventing the progression of hepatic fibrosis is to reduce the activation and transition of hepatic stellate cells into myofibroblasts or to promote hepatic stellate cells’ senescence and apoptosis (Higashi et al.). Activated hepatic stellate cells cause strong cell proliferation and dramatic changes in their stellate morphology, and are accompanied by lipid deposition, degradation imbalance of extracellular matrix, and over-secretion of specific marker protein, such as alpha- smooth muscle actin (a-SMA) (Schinagl et al.). A study has shown that the activat ed hepatic stellate cells migrate with the infiltrating leukocytes into damaged area of the liver (Yagai et al.), whereas inflammatory cells evoke hepatic inflammation (Wan et al.) and secret proinflammatory, as well as profibrotic factors, including transforming growth factor b1 (TGF-bI) (Zhan et al.).
Accordingly, Mebendazole, which is an antimicrotubular agent that possesses a high affinity for tubulin, has been shown to exert an inhibitory effect on collagen bio synthesis and secretion in cell cultures (Soto et al.). These changes were reflected in an intracellular accumulation of total proteins and collagen in fibroblasts and re sult in a marked decrease of its deposit in the extracellular matrix (Soto et al.), therefore this can be directly related to hepatic stellate cells in liver disease. Anoth er study in pancreatic cancer have shown a reduced connective tissue deposition and reduced a-SMA expression in samples treated with Mebendazole in compari son to untreated samples (Williamson et al.). Therefore, when translated to hepatic stellate cells, this proves again the benefit of mebendazole as an anti-fibrotic agent. Further it was shown that Mebendazole has the ability to reduce the levels of TGF- b1 , which is known to stimulate fibrogenesis (Guerini et al.).
Flowever, mebendazole has also been proven to induce cytokine release from PBMC cultures. Stimulated PBMCs released several pro-inflammatory cytokines including TNFa, IL1 b, IFNy, IL6 from PBMCs activated by IL2 and anti-CD3 stimula tion (Rubin et al.). Our studies have also demonstrated that mebendazole en hanced the secretion of IL6, TNFa and IFNy (Figures 4, 5 and 6) which is known to promote inflammation and in the long term can enhance fibrosis. Therefore, to maintain the anti-fibrotic properties of mebendazole while eliminating the negative pro-inflammatory aspects, our strategy is to perform a combination therapy of mebendazole with Ginsenosides, as we have demonstrated that Ginsenoside has a very significant impact on the reduction of secretion of negatively impacting inflam matory cytokines, especially when high and prolonged doses are necessary.
Additionally, fibrotic patients can benefit from Ginsenoside as it has been demon strated that it can attenuate hepatic fibrosis through regulating autophagy process es (Liu et al.). Another study has demonstrated ginsenosides ability to inhibit the TΰRbI/BMAϋ pathway, thereby improving liver fibrosis (Hafez et al.). Further, by regulating c-FLIP pathway-mediated NF-KB activation, ginsenoside can induce the apoptosis of activated hepatic stellate cells (Wu et al.).

The experimental conditions that were performed on A549 cells in the study are summarized in the table below:
The experimental procedure is described as follows:

In addition, 72h following co-culture initiation and treat-ments, su pernatants were collected and effects of test compounds were evaluated on immu ne cell response activation by mean of the quantification of TNFa and IL-6 released levels, as key representative surrogates. TNFa and IL-6 quantification were perfor med using specific HTRF-based detection kits (TECAN Infinite F500 microplate reader).
From these studies, the following points can be depicted: On PBMC cells alone, activated cells were able to proliferate, at the in verse of inactivated cells, and their proliferation was promoted by Atezolizumab (Fi gure 1).
In co-cultures for the immune cell mediated tumor killing assay, addition of human PBMCs - without anti-CD3 activation - to A549 tumor cells was shown not to affect the tumor cell proliferation when compared to the A549 tumor cell mo- no-culture condition. However, and as expected, addition of activated human PBMCs decreased the tumor cell count, an effect visible since 24h-48h after co culture initiation, along with an appearance of an apoptosis signal (staurosporin tre atment showed the apoptosis induction as expected from this positive control). These ef-fects thereby evidencing the killing activity of activated PBMCs were as expected and were shown to tend to be optimized in the presence of Atezolizumab (Figure 2).
- Enhanced killing of cancer cells were demonstrated after exposure with ginseno-side and mebendazole and after exposure with ginsenoside and metformin (Fig. 3d). In fact, tumor cell count reached zero or a negligible level between 96-120 after exposure with ginsenoside and mebendazole and after exposure with gin senoside and metformin (Fig. 3b).
Furthermore, data obtained through released cytokine quantification showed that PBMC activation/activity and its optimization upon PDL1 blockade we re strongly and further confirmed, particularly, by the increased IFNg and TNFa re leased levels in the supernatants of activated PBMCs either alone and in co-culture with A549 tumor cells (Figures 4 & 5). Indeed, on a hand, activated PBMCs, alone, released higher IFNg levels than non-activated cells, and this release was opti mized by atezolizumab (Figure 4). The same was observed with TNFa release, but at a lesser extent modulation (Figure 5).
Both exposure with ginsenoside and mebendazole and exposure with ginseno-side and metformin were shown to lead to very low expressions of TNFa (Fig. 5) and IL-6 (Fig. 6) that are usually highly related to side effects of cancer the- rapies associated with immune checkpoint inhibitors (immuno-oncology), chemothera-py and radiotherapy.
Among the most common inflammatory cytokines as biomarkers of iRAEs is IL-6 which is also known to be a surrogate of immune response, inflammation, tu mor progression and pain. Serum IL-6 is associated with worse prognosis and poor survival in cancer patients. Among the first treatments of iRAEs such severe arthri tis, myocarditis, uveitis, great vasculitis, severe pneumonia, great vasculitis and myasthenia gravis is Tocilizumab (Anti IL-6 Receptor antibody) which inhibits IL-6 signaling. Targeting IL-6 pathway does not activate tumor progression.
Therefore, tumor cell killing without triggering IL-6 overexpression and secreti on pose a great benefit for patients such as inhibiting IL-6 associated cancer cach exia, physical and neuropathic pain and fatigue- thus contributing towards impro ving quality of life. The combination of Ginsenoside and Mebendazole trigger a im- mune-mediated tumor cell killing without the secretion of IL-6 and Therefore, Ginseno-side and Mebendazole combination reduces IL-6 cytokine release com monly associat-ed with cancer cachexia, physical and neuropathic pain, fatigue and poor quality of life.
With respect to treatments with test compounds, cytokine release modu lations were observed both in the condition of activated and non-activated PBMCs, but differed, interestingly, depending on the treatment and on the intended cytokine. o Indeed IFNg released levels (Figure 4) were demonstrated to be modula ted, more strongly, in the configuration of activated PBMCs. While mebendazole was shown to partially decrease IFNg levels in the supernatants, metformin and Gin-senoside showed a complete inhibition. Conversely, R848 was shown to induce an increase in the IFNg amount when applied alone, an effect which seemed to be (i) partially and (ii) completely “antagonized” by (i) mebendazole and (ii) metformin or Ginsenoside Rh2. o As to TNFa levels (Figure 5), also very slight modulations were obtained in the absence of anti-CD3; with R848 showing an increase in the released cytoki ne, which was inhibited by metformin but not by mebendazole.
In co-cultures with activated PBMCs, there was more TNFa released than with in-activated PBMCs, and these levels were not further increased under R848 or mebendazole treatment. On the other hand, metformin and Ginsenoside Rh2 were shown, each alone or when applied in combination together, to completely abolish this release. While this release was strongly inhibited under metformin in combina tion with mebendazole, the inhibitory effect of metformin seemed like partially re versed by R848. o interesting modulations were obtained on IL-6 release (Figure 6). While PBMCs alone either inactivated or activated were shown to secrete a very low amount of IL-6, this secretion was also shown not to be optimized by PDL1 block ade.
However, IL-6 release increased in co-cultures with inactivated PBMCs and even more with activated PBMCs. In both cases, IL-6 levels were shown to be slightly optimized by Atezolizumab.
With regards to compounds treatments, in the absence of anti-CD3, R848 in- terest-ingly displayed a very huge induction of IL-6 release, while the three other corn-pounds - applied either alone or in combination between them - rather showed an inhibitory action. Also, interestingly, the R848-induced IL-6 release was increa- sing-ly inhibited by mebendazole, metformin, and mebendazole+metformin, respec- tive-ly.
In co-culture with activated PBMCs, IL-6 release was very strong in control un treated conditions but remained, slightly, increased by R848 treatment. Also, the inhibi-tory effects of metformin, Ginsenoside Rh2, and mebendazole were still evi denced, both when they were applied each alone or in combination between them thereby underlining a synergistic inhibition. However, these inhibitory effects were shown, interestingly, to be reversed in the presence of R848, suggesting that Explanation of the Figures:
Figure 1: Real-time live cell monitoring of PBMCs, with and without anti-CD3 activation, in the presence and absence of Atezolizumab. PBMCs were cultured in the presence and absence of aCD3 and in the presence and absence of Atezolizumab (1ug/mL). Cell conflu ence was monitored and quantified over a period of ~5 days, as a surrogate measure of immune cell proliferation. Data were normalized and corrected to the baseline and are ex pressed as means ± SEM.
Figure 2: Real-time live cell monitoring of lung A549 tumor cell killing mediated by acti vated PBMCs, under untreated and Atezolizumab-treated conditions.

The respective tumor cells were seeded and 24h later were co-cultured with PBMCs, in the absence (inactive; top graphs) and presence (activated with 0.05 ug/mL CD3+; bottom graphs) under the different condi tions of treatments with compounds. Tumor cell count were monitored and quantified over a period of ~5 days, by mean of a NucRed probe expression and caspase 3/7 fluorescent probe, respectively, as surrogate measures of immune cell killing activity towards tumor cells. Data were normalized and corrected to the baseline and are expressed as means ± SEM.
Figure 8: The synergistic cell killing effect of mebendazole combined with Ginsenoside on the growth of lung A549, breast MDA-MB-231, colon HCT116, Pancreatic PANC1, liver HEPG2 tumor mediated by activated PBMCs. Coefficient of Drug Interaction (CDI) was calculated as follows: CDI = AB/(A c B), where AB represents the ratio between the cell count of the combined treatment and control groups while A or B are the ratio between the cell count of the single drug and the control group. A CDI <1 ndicates synergism, CDI =1 indicates additivity and CDI >1 indicates antagonism. A CDI value less than 0.7 indicates that the drugs are significantly synergistic. Our combination therapy produced a CDI of zero in all cancer cell types, which is the strongest possible indication of synergy.
