Definitions
- the present invention relates to the use of optimized chimeric, humanized or human monoclonal antibodies which are produced in selected cell lines, said antibodies having a high affinity for the CD 16 receptor of effector cells of the immune system but also the property of inducing the secretion of cytokines and interleukins, in particular IFN ⁇ or 1TL2, for the treatment of pathologies for which the target cells express only a low antigenic density and in which the effector cells can only be recruited at low amount.
- HLA class 1 or class 2 molecules for example in the case of carcinomas, melanomas, ovarian cancers, prostate cancers are generally poorly expressed on the surface of target cells. tumor.
- HLA class 1 or class 2 molecules express only few viral molecules on their membrane.
- the objective is to obtain new antibodies having a better efficacy compared to current antibodies, which would make it possible to envisage their use in therapy for pathologies having few expressed molecular targets or a low antigenic density as well as a number limited effector cells capable of being activated.
- CD 16 can be further reinforced by additional conditions aimed at producing antibodies which also induce the production of cytokines, in particular the production of IFN ⁇ or IL2 by cells of the immune system.
- the two characteristics mentioned above complement each other. Indeed, the production of IFN ⁇ or IL2 induced by the antibodies selected by the process of the invention can reinforce the cytotoxic activity. The mechanism of action of such activation is probably due to an autocrine regulation of effector cells. It can be postulated that the antibodies bind to CD 16 causing cytotoxic activity but also induce the production of Y IFN ⁇ or IL2 which ultimately leads to an even greater increase in cytotoxic activity.
- the invention relates to the use of an optimized chimeric, humanized or human monoclonal antibody characterized in that: a) it is produced in a cell line selected for its glycosylation properties of the Fc fragment of an antibody, or b ) the glycan structure of Fcgamma has been modified ex vivo, and / or c) its primary sequence has been modified so as to increase its reactivity towards Fc receptors; said antibody having i) an ADCC level via Fc ⁇ RIII (CD 16) greater than 50%, preferably greater than 100% for an E / T ratio (effector cells / target cells) less than 5/1, preferably less than 2 / 1, compared to the same antibody produced in a CHO line; and ii) a production rate of at least one cytokine by an effector cell of the immune system expressing the CD 16 receptor greater than 50%, 100% or preferably greater than 200% compared to the same antibody produced in a CHO line; for the preparation of a medicament intended for the treatment of pathologies
- cytokines released by the optimized antibodies are chosen from interleukins, interferons and tissue necrosis factors (TNF).
- the antibody is selected for its ability to induce the secretion of at least one cytokine chosen from IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7 , IL-8, IL-9, IL-10, ... TNFa, TGF ⁇ , IP10 and IFN ⁇ by effector cells of the immune system expressing the CD 16 receptor.
- cytokine chosen from IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7 , IL-8, IL-9, IL-10, ... TNFa, TGF ⁇ , IP10 and IFN ⁇ by effector cells of the immune system expressing the CD 16 receptor.
- the antibody selected has the capacity to induce the secretion of IFN ⁇ or IL2 by effector cells of the immune system expressing the CD 16 receptor or of 1TL2 by the Jurkat CD 16 cell for a small number of antigenic sites. present on the surface of target cells or for a small number of antigens accessible to antibodies.
- the secreted IFN ⁇ or IL2 level reflects the quality of the antibody fixed by the CD 16 receptor as regards its integrity (Fc function) and its efficiency (antigenic site) of binding to the antigen.
- the secretion of IFN ⁇ or IL2 by cells of the immune system can activate the cytotoxic activity of effector cells.
- the antibodies of the invention are also useful for the treatment of pathologies for which the number of activated or recruited effector cells is low.
- Effector cells can express endogenous CD 16 or be transformed.
- the term transformed cell means a cell genetically modified so as to express a receptor, in particular the CD 16 receptor.
- the antibody of the invention is capable of inducing the secretion of at least one cytokine by a leukocyte cell, in particular of the family of NK (natural killer) or by cells of the monocyte group -macrophages.
- a Jurkat line transfected with an expression vector coding for the CD 16 receptor as effector cell is used for the selection of the antibodies. This line is particularly advantageous because it is immortalized and develops indefinitely in culture media.
- the level of interleukin IL2 secreted reflects the quality of the antibody fixed by the CD 16 receptor as regards its integrity (Fc function) and its efficiency (antigenic site) of binding to the antigen.
- the optimized antibody can be prepared after being purified and / or modified ex vivo by modification of the glycan structure of the Fc fragment.
- any suitable chemical, chromatographic or enzymatic means can be used to modify the glycan structure of the antibodies.
- the antibody can be produced by cells of rat myeloma lines, in particular YB2 / 0 and its derivatives.
- Other lines can be selected for their properties of producing the antibodies defined above.
- the production in CHO serves as a reference (CHO being used for the production of drug antibodies) to compare and select the production systems leading to the antibodies according to the invention.
- the general glycan structure of the antibody corresponds to a biantennary type, with short chains, low sialylation, mannoses and GlcNAc at the non-intermediate terminal attachment point, and low fucosylation.
- the level of intermediate GlcNac is not zero.
- the invention relates to the use of an antibody described above for the preparation of a medicament intended for the treatment of a pathology escaping the immune response notably chosen from hemolytic disease of the newborn, Sézary Syndrome , chronic myeloid leukemia, cancers for which the antigenic targets are weakly expressed, in particular breast cancer, pathologies linked to the environment targeting in particular people exposed to polychlorinated biphenyls, infectious diseases, in particular tuberculosis, chronic fatigue (CFS), parasitic infections such as schistosomules.

- Figure 12 Secretion of gamma IFN by NK cells, induced by anti-CD20 and anti-HLA-DR antibodies expressed in CHO and YB2 / 0 (324 03 082).
- Example 1 ADCC induced by anti-Rhesus antibodies as a function of the number of antigenic sites.
- the same sequence coding for an IgG1 specific for the Rhesus D antigen is transfected into CHO and YB2 / 0.
- the cytotoxic activity of the antico ⁇ s is compared with respect to Rhesus positive red cells expressing on their surface different quantities of Rhesus antigen, ie: normal O + red cells (10-20,000 sites) and red cells over-expressing the antigen rhesus (> 60,000 sites).
- ADCC activity of the antico ⁇ s expressed in CHO (triangle) or YB2 / 0 (square) on normal red cells (N, empty) or overexpressing the Rhesus antigen (GR6, full) are compared.
- the same sequence coding for an IgG1 specific for the HLA-DR antigen is transfected into CHO and YB2 / 0.
- the cytotoxic activity of the antico ⁇ s is compared with respect to the Raji cell in the presence of different effector / target ratios (see Figure 2).
- the relative percentage of lysis induced by the antico ⁇ s expressed in CHO (100% being the value of the antico ⁇ s expressed in YB2 / 0 for each ratio) is 61%, 52%, 48% and 36% respectively.
- the antico ⁇ s expressed in YB2 / 0 proves to be more cytotoxic than when it is produced by
- Example 3 ADCC Induced by Anti-HLA DR Antibodies as a Function of the Quantity of Antigens Accessible
- the same sequence coding for an IgG1 specific for the HLA-DR antigen is transfected into CHO and YB2 / 0.
- the cytotoxic activity of the antico ⁇ s is compared with respect to the Raji cell in the presence of different effector / target ratios (E / T ratio).
- the cytotoxic activity of the antico ⁇ s is compared with respect to Raji cells whose antigenic sites have been previously blocked with increasing amounts of an inactive (non-cytotoxic) murine antico DRs anti-HLA-DR, so as to have a decreasing number of 'HLA-DR antigens available with regard to the antico ⁇ s to be evaluated (see Figure 3).
- the same sequence coding for an IgG1 specific for the HLA-DR antigen is transfected into CHO and YB2 / 0.
- the activation of the effector cell (secretion of IL2 by Jurkat CD 16) induced by antico ⁇ s is compared with respect to Raji cells whose antigenic sites have been previously blocked with increasing amounts of a murine anti-HLA antico ⁇ s DR, so as to have a decreasing number of HLA-DR antigen available vis-à-vis the antico ⁇ s to be evaluated (see Figure 4).
- Example 5 ADCC induced by anti-CD20 antibodies as a function of the quantity of antigens.
- the same sequence coding for an IgG1 specific for the CD20 antigen is transfected into CHO and YB2 / 0.
- the activation of the effector cell (secretion of IL2 by Jurkat CD 16) induced by antico ⁇ s is compared with respect to Raji cells whose antigenic sites have been previously blocked with increasing amounts of an inactive murine antico ⁇ s anti-CD20 , so as to have a decreasing number of CD20 antigens available with respect to the antico ⁇ s to be evaluated (see Figure 5).
- Pantico ⁇ s optimized that is to say produced in YB2 / 0 can thus relate to target cells expressing on their surface a poorly expressed antigen.
- the optimized antico ⁇ s prove to be particularly useful for therapeutic applications when the target cells express on their surface few antigens, and this whatever the antigen.
- Example 7 Correlation in vitro between ADCC and release of IL-2 by the Jurkat CD16 cell.
- the monoclonal antibody (Mab) DF5-EBV was produced by human B Lymphocytes obtained from an immunized D-negative donor and immortalized by transformation with EBV. This antibody was used as a negative control since in a clinical trial it was unable to remove Rhesus positive red blood cells from the circulation.
- the monoclonal antico Ms (Mab) DF5-YB2 / 0 was obtained by expressing the primary sequence of DF5-EBV in the line YB2 / 0.
- the monoclonal antibody R297 and other recombinant antibodies were also expressed in YB2 / 0.
- Antico ⁇ s are tested in vitro for their ability to induce lysis of red blood cells treated with papain using mononuclear cells (PBL) as an effector.
- PBL mononuclear cells
- IVIg is thought to bind with high affinity to FcgammaRI (CD64).
- the two Mab DF5-YB2 / 0 and R297 induce lysis of red blood cells at a level comparable to that of WinRho polyclonal antibodies.
- the Mab DF5-YB2 / 0 and R297 induce lysis of red blood cells at a level comparable to that of WinRho polyclonal antibodies.
- the Mab DF5-YB2 / 0 and R297 induce lysis of red blood cells at a level comparable to that of WinRho polyclonal antibodies.
- IL2 produced by effector cells activated by complex antigen-antico ⁇ s immune cells, induces activation of T lymphocytes and NK cells, which can go as far as stimulating cell proliferation.
- IFN ⁇ stimulates the activity of
- CTLs and can enhance the activity of macrophages.
- TNF produced by effector cells activated by immune systems antigen-antico ⁇ s complexes, stimulates the proliferation of macrophages and lymphocytes infiltrating tumors.
- LTL-IRa is a cytokine that competes with IL1 at its receptor and thus exerts an anti-inflammatory effect.
- LTL10 is a molecule that inhibits the activation of different effector cells and the production of cytokines.
- the IL10 produced by the effector cells activated by antigen-antico ⁇ s complex immune systems can have a regulatory role in the cytotoxic activity of the antico ⁇ s with respect to normal cells, but expressing antigens common with the target cells targeted, and also modulate the effects of TNF alpha.
- Example 11 Induction of the secretion of cytokines by different effector cells.
- cytokine synthesis is dependent on the presence of the target. There are few differences in the ability of anti-D R297 and polyclonal antibodies to induce the production of different cytokines. On the other hand, AD1 is very often not inducing secretion of cytokines.
- the monoclonal antibody R297 and the anti-D polyclonal antibody anti-D WinRho induce an important secretion of TNF alpha, less strong but greater than those induced by AD1 of IL6, of IFN gamma, IP10, TNF alpha and TGF Beta.
- the secretion dIL6, of IFN gamma, of IP10 increases, but that of TNF alpha and the TGF Beta decreases (FIG. 8).
- the monoclonal antico ⁇ s R297 and the polyclonal anti-D anti-D WinRho induce a very weak secretion, but superior to AD1, of IL2, of IFN gamma, of IPlO and of TNF by the polymorphonuclear cells. This secretion is dependent on the concentration of antico ⁇ s ( Figure 9).
- the monoclonal antibody R297 and the anti-D polyclonal antibody anti-D WinRho induce significant secretion of IFN gamma, IP10 and TNF by the NK cells. This secretion is dependent on the concentration of antico ⁇ s ( Figure 10).
- Example 11 Optimized chimeric anti-CD 20 and anti-HLA DR antibodies produced in YB2 / 0
- Anti-CD20 the chimeric anti-CD20 antico ⁇ s transfected in YB2 / 0 is compared to a commercial anti-CD20 antico (s produced in CHO (Rituxan).
- Anti-HLA DR the same sequence encoding the chimeric anti-HLA DR antibody is transfected into CHO (Bl 1) or YB2 / 0 (4B7).
- Target cells Raji cells expressing on their surface the CD20 antigen and HLA-DR
- Effector cells human NK cells purified by negative selection from a human blood bag.
- TNF alpha The results are expressed in pg / ml of TNF alpha assayed in the supernatants. On the abscissa are the different concentrations of antico ⁇ s added to the reaction mixture ( Figure 11).
- the chimeric anti-CD 20 and anti-HLA DR antico ⁇ s produced in YB2 / 0 induce higher levels of TNF in the presence of their target (Raji) compared to the same antico ⁇ s produced in CHO.
- the amount of TNF alpha is dose dependent on the concentration of added antico ⁇ s.
- 10 ng / ml of antico ⁇ s 5 times more TNF alpha is induced with the antico ⁇ s produced in YB2 / 0 compared to the antico ⁇ s produced in CHO.
- IFN gamma The results are expressed in pg / ml of IFN gamma assayed in the supernatants. On the abscissa are the different concentrations of antico ⁇ s added to the reaction mixture ( Figure 12).
- the chimeric anti-CD 20 and anti-HLA DR antibodies produced in YB2 / 0 induce higher levels of gamma IFN in the presence of their target (Raji) compared to the same antibodies produced in CHO.
- the amount of IFN gamma is dose dependent on the concentration of added antico ⁇ s. At all the concentrations used (10 to 200 ng / ml) the anti-HLA DR antico ⁇ s produced in CHO does not induce IFN gamma secretion, while 40 ng / ml of the antico ⁇ s produced in YB2 / 0 induces approximately lOOOpg / ml of IFN gamma.
