Definitions
- Anti-cancer therapy using a leptin antagonist and an iNKT-cell activator using a leptin antagonist and an iNKT-cell activator
- the present invention relates to the treatment of cancer. More specifically the invention shows that the anti-cancer activity in mammals can be augmented by administering to the mammalian host a combination of a synergistically effective amount of a leptin antagonist and an invariant natural killer T (iNKT) cell activator.
- a synergistically effective amount of a leptin antagonist and an invariant natural killer T (iNKT) cell activator.
- the anti-cancer drugs may be anti-metabolites, alkylating agents, antibiotics, antibodies, immune-stimulants, cytokines and the like. Combinations of said drugs are administered in an attempt to obtain a synergistic, cytotoxic effect on most cancers, e.g., carcinomas, myelomas, melanomas, lymphomas and sarcomas, and to reduce or eliminate emergence of drug-resistant cells and to reduce side effects of each drug.
- MM multiple myeloma
- BM bone marrow
- Fatty deposits can occupy up to 70% of the BM cavity with aging, yet little attention has been given to the role of adipocytes and adipokines in MM development.
- Adipocytes may contribute to MM by promoting migration and proliferation through secretion of adipokines such as leptin and are known to be negative regulators of the hematopoietic environment (Naveiras O, Nardi V, Wenzel PL, Fahey F, Daley GQ, Nature. 2009;460(7252):259-263). Recently, it became clear that adipose tissue contains a wide range of immune cells. Reciprocal interactions of immune mediators with adipocytes have been described giving rise to the emerging field of the immunometabolism (Mathis D, Shoelson S., Nat. Rev. Immunol. 2011 ;11 (2):81 doi).
- Invariant natural killer T (iNKT) cells a prototypic T cell subset with important roles in anti-tumour immunity, have been shown to closely interact with adipocytes in a CD1d dependent manner (Huh JY, Kim I, Park J, et al., Mol. Cell. Biol. 2013;33(2):328-339).
- MM defective IFN- ⁇ production by iNKT cells and reduced iNKT cell frequencies are observed in patients and different animal models (Dhodapkar M V, Geller MD, Chang DH, et al., J. Exp. Med. 2003; 197(12): 1667-76).
- CD1d expression levels on antigen presenting cells are progressively downregulated upon MM progression (Spanoudakis E, Hu M, Naresh K, et al., Blood. 2009;113(11):2498— 507).
- a crosstalk between adipose tissue and iNKT cell function plays a crucial role in MM development through release of the adipokine leptin.
- iNKT cells have been shown to be involved in various immune responses, both in mice and in humans, ranging from self-tolerance to development of autoimmunity and responses to pathogens and tumours (Taniguchi, M. et al., Annu Rev Immunol. 2003;21 :483).
- ⁇ -galactosylceramides (a -GalCer) have originally been isolated from a marine sponge Agelas mauritianus and it was found that these compounds exhibit anti-tumour and immuno-stimulating activity in pre-clinical animal models (see for example patent EP0609437B1).
- the use of a-GalCer and analogous CD1d ligands has allowed to define iNKT cells as potent immunoregulatory cells that bridge the innate and adaptive response.
- the design of various analogs of a-GalCer and its non-glycosidic analogues is extensively described in literature (Kerzerho, J. et al., J Immunol.
- Modifications include either the lipid tails responsible for CD1d binding or the sugar moiety that directly interacts with the TCR.
- KRN7000 is a synthetic a -GalCer that has been most frequently used in experimental studies. Clinical studies using KRN7000 have been disappointing since no clinical anti-tumour effects were recorded (Giaccone G et al (2002) Clin Cancer Res 8: 3702). Furthermore, it was observed that the use of sequential doses of a -GalCer can lead to an anergic state of T-cells (Parekh W et al (2005) J Clin. Invest. 115(9):2572-83).
- BM changes occurring during aging is the increase in adipocyte numbers.
- Leptin an adipokine released by adipocytes crucial in energy homeostasis, also displays immune modulatory properties but its role in anti-tumour immunity is unclear.
- leptin and iNKT leptin receptor (LR) levels are linked to disease progression.
- Leptin controls iNKT cells by inhibiting their function, preventing long term anti-tumour effects in MM.
- LR signaling on activated iNKT cells markedly promotes tumour protection by alleviating iNKT cell anergy.
- leptin-leptin receptor as a novel check point inhibitor strategy to target MM.
- blocking leptin receptor signalling on activated iNKT cells protects against multiple myeloma by modulating iNKT anergy.
- the use of a therapeutic amount of a leptin antagonist in combination with an iNKT-cell activator provides a surprising synergism in treating various forms of cancer.
- compositions which comprise a leptin antagonist and an iNKT-cell activator.
- said iNKT-cell activator is a-galactosylceramide or a functional derivative thereof.
- a functional derivative retains the capacity to activate invariant natural killer cells.

- the leptin receptor antagonist can also be administered over a long period, for example over weeks, months or even years. This can be useful to suppress tumour development and tumour growth.
- the administration with the iNKT-cell activator is weekly for at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9 or at least 10 consecutive weeks.
- the iNKT-cell activator can also be administered over a long period, for example over months or even years. This can be useful to suppress tumour development and tumour growth.
- the dose and dosage regimen will depend mainly on whether the leptin receptor antagonist and iNKT-cell activator are being administered separately or as a mixture, the type of cancer, the patient, and the patient's history. The amount must be effective to achieve a tumour reduction that is synergistic. If multiple doses are employed (such as preferred with the leptin receptor antagonist) the frequency of administration will depend, for example, on the type of host and type of cancer, dosage amounts, etc. For some types of cancers, daily administration will be effective, whereas for others, administration every other day or every third day will be effective, but daily administration will be ineffective. The practitioner will be able to ascertain upon routine experimentation which route of administration and frequency of administration are most effective in any particular case.

- parenteral administration examples include subcutaneous, intravenous, intraarterial, intramuscular, and intraperitoneal administration(s).
- the dosage amount which appears to be most effective herein is one which results in tumour regression or complete regression and is not toxic to the host. This optimum level will depend on many factors, for example, on the type of host and type of cancer, route, schedule of administration, existing tumour burden, the type of iNKT-cell activator and the leptin receptor antagonist, and the definition of toxicity. Toxicity to the host may be defined by the extent and type of side effects or by the amount of body weight loss or by death after a certain period of time. If body weight loss is the criterion for toxicity, typically a loss of 10-20% by weight will be tolerated, with greater than 20% loss being considered toxic.

- 5x10 4 5T33MMW cells, 5x10 4 iNKT cells, 10 5 a-GalCer loaded or vehicle loaded DCs were co-cultured in supplemented RPMI-1640 medium.
- Leptin (0,25 ⁇ / ⁇ ) and/or bispecific nanobody 2.17m-Alb ( ⁇ / ⁇ ) were added. Construction, production, and purification of the nanobody 2.17m-Alb was described elsewhere (Zabeau L, Verhee A, Catteeuw D, et al., Biochem. J. 2011 ;441 :425-434).
- Supernatants of co-cultures were collected after 72 h for IFN- Y measurements by ELISA (eBioscience), following manufacturer's instructions.
- mice C57BL/KaLwRij mice were inoculated as described previously and weekly i.p. injected with 2 ⁇ g a-GalCer (Vanderkerken K, Croucher P., Immunol. Rev. 2003;194:196-206; Radl J, Glopper E De, Schuit HRE, Zucher C, J. Immunol. 1979;122(2):609— 613).
- Serum IFN- ⁇ levels were determined by ELISA. Mice were treated during 10 days with 2.17m-Alb or control BclL10-mAlb (i.p., 200 g mouse -1 day -1 ) and weighed daily.
- the melanin-positive melanoma B16BI6 cells (Hart ef al., 1979) are cultured in RPM1 1640 (Invitrogen) supplemented with 10% FCS, 50 lU/ml penicillin G, 50 ⁇ g/ml streptomycin sulphate, 2 mM L-glutamine and 0,4 mM Na-pyruvate.

- mice are inoculated with 6x10 5 cells (in 50 ⁇ PBS) subcutaneously in the back just in front of the hind limb. Treatment is started when the tumour size index (TSI), i.e. the product of the largest perpendicular diameters in mm, reached 10-50 (day 7-12).
- TTI tumour size index
- mice are inoculated with 1x10 5 cells (in 50 ⁇ PBS) subcutaneously in the back just in front of the hind limb. Treatment is started when the tumour size index (TSI), i.e. the product of the largest perpendicular diameters in mm, reached 10-50 (day 8-14).

- mice receive a-GalCer, 2.17m-Alb or control BclM O- mAlb (i.p., 200 g mouse-1 day-1) according to the treatment scheme above.
- DCa-G dendritic cells
- LR could be a potential target in MM by using a 2.17-mAlb nanobody which inhibits binding of leptin to the leptin receptor (Zabeau, L. et al., Biochem. J. 2011 ;441 :425-434).
- a-GalCer stimulated iNKT cells significantly decreased BM tumour load and serum M-spike in MM diseased mice (Nur, H. et al., PLoS One. 2013;8(5):e65075; Mattarollo, S.R. et al., Blood. 2012;120(15):3019-3029).
- mice receiving the combined regimen with LR antagonist displayed intact IFN- ⁇ levels after a second restimulation ( Figure 2E).
- LR antagonists therefore bypass hypo- activation of iNKT cells ( Figure 2E). This maintained iNKT activity had effects on tumour burden, as measured by the serum M spike.
- C57BL/6 mice bearing a subcutaneously growing B16BI6 tumour are treated with a combination of the specific iNKT cell agonist alfa-GalCer and a leptin receptor antagonist.
- Treatment with either a-GalCer or a leptin receptor antagonist alone has no significant effect on tumour growth, while the combination of a-GalCer and the leptin receptor antagonist results in reduced tumour growth.
- mice bearing a subcutaneously growing 4T1 tumour are treated with a combination of the specific iNKT cell agonist alfa-GalCer and a leptin receptor antagonist.
- Treatment with either a-GalCer or a leptin receptor antagonist alone has no significant effect on tumour growth, while the combination of a-GalCer and the leptin receptor antagonist results in reduced tumour growth.
