Definitions
- the present invention relates to the field of immunology, endocrinology, oncology and reproduction, and in particular it is based on the simultaneous generation of a potent immune response against the entire GnRH molecule and especially against the amino and carboxyl ends of this hormone.
- GnRH - Gonodatropin-Releasing Hormone also known as the Luteinizing Hormone-Releasing Hormone (LHRH)
- LHRH Luteinizing Hormone-Releasing Hormone
- FSH follicle-stimulating hormone
- LH Luteinising hormone
- LHRH The role played by LHRH in the regulation of fertility is well known.
- diseases are related to gonadotropins and gonadal steroid hormones, particularly estrogens and testosterone.
- diseases include breast, uterine and other types of gynecological cancer, endometriosis, uterine fibrosis, prostate cancer and benign prostatic hyperplasia, among others.
- Castration or surgical or chemical gonadectomy is one of the most effective methods in the therapeutic intervention of hormone-dependent neoplasms (Huggins C, Hodges CV. Studies on prostatic cancer. I. The effect of castration, of estrogen and of androgen injection on serum phosphatases in metastatic carcinoma of the prostate. Cancer Researh 1941; 1: 293-7). In livestock production, castration is used to avoid the bad smell and taste of meats from adult male animals of economic interest. Proc. Soc. Exp. Biol. Med 175: 259-281, 1984. Meloen RH et al. Efficient ⁇ mmunocastration of male piglets by immunoneutralization of GnRH using a new GnRH-like peptide.
- GnRH analogues are among the most used drugs in the treatment of prostate, ovarian and breast cancer, which exert their action through androgenic or estrogenic deprivation and / or the direct effect on cancer cells.
- the direct mechanism through which these analogues and antagonists of GnRH exert their action has been related to "deinsitization" and the deregulation of GnRH receptors when they are administered chronically.
- GnRH / LHRH analogs are the active immunization with the native hormone or with its peptide-mimetics, which can serve as vaccines when they are bound to more immunogenic molecules such as tetanus, diphtheria toxoid or their epitopes, Ia KLH (Keyhole Limpet Hemocyanin) or BSA (Bovine serum albumin), among others.
- Ia KLH Keyhole Limpet Hemocyanin
- BSA Bovine serum albumin
- the construction process of the proposed molecules contemplates the chemical union by synthesis, the conjugation or the cloning in the form of fusion protein of the GnRH or its mimetics with carrier molecules.
- the carrier molecules can be complete proteins, or their fragments or epitopes, say Tetanus Toxoid (TT), Neisseria Meningitides P64K protein, hepatitis B surface antigen, or hepatitis B virus envelope antigen, etc.
- TT Tetanus Toxoid
- Neisseria Meningitides P64K protein Neisseria Meningitides P64K protein
- hepatitis B surface antigen hepatitis B virus envelope antigen
- the present invention is based on the combination in the same immunization scheme of 2 variants of the natural GnRH / LHRH hormone and / or its mimetics, including retro-inverse variants, synthesized based on D amino acids, where the GnRH variants are they generate, through chemical synthesis, the conjugation or the use of DNA chimeras of the GnRH interchangeably linked by the carboxyl and amino terminal ends to a carrier molecule of the TT type, or its epitopes, in order to achieve a more potent and rapid immune response against endogenous GnRH.
- the carboxyl and amino terminal variants (referred to the binding site of the GnRH to the carrier molecule) can be administered in unison in the same preparation or separated, sequentially or alternately in the same immunization schedule .
- the novelty of this invention lies in the synergistic effect that it produces on the immune system, the active immunization with the 2 GnRH variants mentioned above and which we refer to as: terminal carboxyl (variant in which the carrier is attached to the terminal carboxyl of GnRH or its mimetics) and amino terminal (variant in which the carrier is attached to the amino terminal end of the GnRH or its mimetics), once they are administered as part of the same formulation, producing a rapid and potent ablation of sex hormones male and female (androgens and estrogens respectively), which results in a vigorous immunocastratory action and hence its effectiveness in the immunocastration of animals of economic interest and pet animals, in the control of fertility in humans, as well as in the treatment of hormone-sensitive tumors;
- the combination described not only represents the sum of the action of the two types of variants (carboxyl terminal and amino terminal) but also supposes a synergism in its action on the immune system that translates into a similar effect on target organs , once both variants are administered in the combinations described above.
- the present invention has the advantage over the similar ones described above, a faster and more potent action on the target organs (testicles, prostate, ovaries ... etc) and / or on sex hormone dependent tumors (prostate, breast, ovaries, endometrium, salivary glands, testicles, etc); thanks to the synergism achieved with the mixture of the carboxyl and amino terminal variants.
- the GnRH molecule in its natural form or its mimetics can be directly linked in the process of peptide synthesis to a carrier molecule, or chemically conjugated or cloned in the form of a fusion protein to molecules of recognized immunogenic power, to form two different variants; terminal carboxyl and amino terminal.
- These variants can use as carriers, some of the most frequently reported proteins for this purpose or their epitopes, say Tetanus Toxoid, Dimeric Toxoid, Neisseria meningitides P64K protein, Hepatitis B surface antigen, Hepatite B envelope antigen , etc., so that this mixture causes a rapid and powerful immunological response, whose synergism, leads to the ablation of the GnRH and the hormones involved in the GnRH / LH-FSH / Testosterone / Estrogen cascade.
- Tetanus Toxoid Dimeric Toxoid
- Neisseria meningitides P64K protein Hepatitis B surface antigen
- Hepatite B envelope antigen etc.
- the variants, carboxyl terminal and amino terminal can be used in the same formulation in different proportions, where the ratio between the carboxyl terminal variant with respect to the amino terminal varies from 10:90 to 80:20 (weight / weight).
- the GnRH molecule that has the carrier linked by its terminal carboxyl end constitutes in all cases at least 10% of the total amount of the mixture, and in turn the amino terminal variant represents 20% of the mixture at least total
- the GnRH, carboxyl and terminal amino molecules can be linked to the same carrier, either in one case by the amino and in the other by their terminal carboxyl or, conversely, a variant, say the terminal carboxyl, can be be attached to a carrier molecule and the other, say amino terminal, can be linked to another.
- the immunogenic mixture can be constituted, for example, by GnRH or its mimetics linked in one case to a carrier such as TT or one of its epitopes and in the other to the p64K protein of the Neisseria meningitides bacteria or the antigen of Ia hepatitis B envelope or its epitopes or other carrier molecule of proven immunogenicity.
- a carrier such as TT or one of its epitopes and in the other to the p64K protein of the Neisseria meningitides bacteria or the antigen of Ia hepatitis B envelope or its epitopes or other carrier molecule of proven immunogenicity.
- This type of combination allows the carboxyl and amino terminal variants of GnRH to be mixed with oily adjuvants of the Montanide type, or Water-soluble adjuvants of the alumina type, QS 21 or others, a faster and more potent immune response against GnRH is obtained than that observed using other immunogen variables.
- the potential of the described formulation can be significantly increased, if immunostimulants such as very small size proteoliposomes (VSSP), obtained from the mixture of the lipoproteins of the wall, are also added to the preparation.
- immunostimulants such as very small size proteoliposomes (VSSP), obtained from the mixture of the lipoproteins of the wall, are also added to the preparation.
- VSSP very small size proteoliposomes
- This invention can be used for the immunization of a wide range of vertebrates and especially its use as an immunogen in mammals for the sterilization of pet animals, such as dogs, cats, etc., or for the control of the fertility of wild species like rodents, squirrels and
- the proposed combination ensures a higher percentage of homogeneity in immunocastration, as for example. pigs, goats, etc. to avoid the unpleasant smell that occurs in the meat and fat of these animals. It also allows to produce controlled sterilization or the decrease in the aggressiveness of animals of economic importance in the herds, as is the case of bulls, buffalo, horses and other mammals.
- the use of this invention has direct application in the treatment of prostate and breast cancer, as well as in cancer of the uterus, ovary, testis, submaxillary gland, pituitary pathologies, and other types of hormone sensitive neoplasms. Obtaining an immunogenic preparation of the carboxyl terminal type as one of the components of the combination.
- the carboxyl-terminal variant can be constituted in one of the cases by the natural GnRH molecule or one of its mimetics, say the GnRHmI molecule of sequence QHWSYPLRPG linked to the epitope T helper of the tetanus toxoid 830-844 , QYIKANSKFIGITEL, to the 0 P48-P64K peptide of the Neisseria meningitides of the IPGVAYTSPEVAWVG sequence, or to the complete P64K molecule or other carriers such as the diphtheria toxoid, the hepatitis B surface antigen, the hepatitis B envelope antigen, antigens of the circumsporozoite, etc.
- the natural GnRH molecule or one of its mimetics say the GnRHmI molecule of sequence QHWSYPLRPG linked to the epitope T helper of the tetanus toxoid 830-844 , QYI
- GnRH a natural GnRH molecule or some of its mimetics, such as the case of the GnRHmI described above linked by its amino terminal end to the epitope 830-844 tetanus toxoid to form the molecule (QYIKANSKFIGITELGGQHWSYPLRPG) or the union of This is because of its amino-terminal to the P48 peptide of the P64K protein of the Neisseria Meningitides bacterium (IPGVAYTSPEVAWVGGGGQHWSYPLRP), or another carrier molecule of the type mentioned above, constitutes an active principle with a much greater potential for immunogenicity against the endogenous GnRH hormone, that produced by the carboxyl terminal variant described above.
- Testimony 1 this is that individuals immunized with the variant TT-GnRHmI seroconvert 'against Ia natural hormone GnRH after only one immunization, reaching titers ranging from 1: 6000 to 1: 12000 after Ia 3rd or 4th immunization and in turn, the immunization with the amino-terminal variant (P48-P64K-GnRHm1) generates a significant antibody response in 90% of the animals after only one immunization and anti GnRH antibody titers between 1: 5000 and 1: 12000 after 4 administrations.

- Example 1 Immunogenicity of the carboxyl and amino-terminal I O variants of GnRHmI using TT as a carrier molecule.
- Testosterone level determination Testosterone levels were determined using the TESTO CT2 kit (CisBio, International, France). 5 For this procedure, 25 ⁇ l of serum was taken from each sample and dispensed directly into pre-coated tubes. The samples were incubated in duplicate. Finally the tubes were washed with distilled water and read in a gamma counter. The results were expressed in nmol / L.
- the GnRH molecule as explained, by sharing 100% homology in all mammals and at a high level in the upper vertebrates, and being very small (only ten amino acids), gives this peptide very little
- the group immunized with the amino terminal variant with the peptide had a 100% seroconversion after the first immunization, while the group immunized with the carboxyl variant
- Figure 3 relates the anti GnRH antibody titers of the sera of each of the experimental groups.
- the 5 TT-GnRHmI group was the one that showed the highest speed in the appearance of anti-GnRH titles, which ranged between 1/6000 and 1/12000, between 75 and 100 days after the experiment began .
- vahante (50/50) and (70/30) showed similar titers of anti GnRH antibodies.
- the variant (50/50) was the one that showed the highest speed 0 of the appearance of the titles.
- Example 2 Immunogenicity of the carboxyl and amino-terminal variants of GnRHmI using the P48-P64K peptide as a carrier molecule. 2.1. Experimental Groups 1 - Placebo
- the group immunized with the amino terminal variant with the peptide (P48-P64K-GnRHm1) had 100% serocoriversion after the first immunization, while the group immunized with the carboxyl terminal variant represented by the peptide ( GnRHmI -P48-P64K), showed between 70-80% seroconversion, only after the 3rd immunization.
- the combination (50/50) of the mixed carboxyl and amino terminal variants had 100% seroconversion after the second immunization.
- the combination of the carboxyl and amino terminal variants in the proportion (70/30), and the alternate immunization scheme developed 100% seroconversion, after the third immunization (Fig. 7).
- Figure 8 lists the anti-GnRH antibody titers of the sera of each of the experimental groups. In this graph it is observed that the group P48-P64K-GnRHm1 was the one that showed the highest speed in the appearance of the anti GnRH titles, which ranged between 1/5000 and 1/8 000, at the end of the experiment. Of the combined variants, the variant (50/50) and (70/30), showed similar titers of anti GnRH antibodies. However, the variant (50/50) was the one that showed the highest speed of appearance of the titles.
- the alternative immunization scheme with the variants GnRHm1-P48-P64K and P48-P64K-GnRHm1 showed levels of immunogenicity similar to those awakened when the variant was used (70/30), although it was not possible to maintain the titles at levels as high as the first.
- the titles appeared later than the rest of the experimental groups, and did not reach levels higher than 1/1000 in the best cases.
- the carboxyl and amino terminal variants mixed in different proportions in the same immunization scheme achieve an immunological response significantly higher than that obtained with the individual carboxyl 5 terminal peptide, and although lower than the titles obtained with the use of Ia aminoterminal variant, the biological effect is significantly superior to the 2 variants administered individually. Similar results were observed when both peptides were inoculated in the same immunization scheme alternately (Fig. 8, 9 and 10). 0 Example 3. Correlation of the humoral response awakened against different areas of the hormone GnRH and its effect on target organs. The combination of these effects. Once the antibody titres were analyzed, a correlation analysis between them and the effect on the target organs (prostate and testicles) was performed.
- the Effect of the treatment was considered as the unit minus the ratio of the average of the weight of the organs (prostate and testicles) in the treated animals (PTreatment) and the average of the weight of the organs target in placebos animals (PPIacebo).
- ETreatment 1 - (PTreatment / PPIacebo) (1)
- Tables No. 1 a and 1 b for the combination carboxyl + amino terminal (50/50), the experimental effect on the prostate and the testicles, was superior to the theoretical or expected effect, the synergistic effect of this combination being demonstrated in the reduction of the size of these organs using any of the carrier molecules described in Figure 1.
- Example 4 Therapy experiments using the individual GnRHmI-TT and TT-GnRHmI variants and their combinations (GnRHmI-TT + TT-GnRHmI) in adult Copenhagen rats implanted with the Dunning R3327-H cell line.
- Tumor fragments (2 x 2 x 2 mm) of the Dunning R3327-H murine tumor model were transplanted subcutaneously (sc). in the distal area of the right posterior limb of adult Copenhagen rats weighing between 150 and 200 g. (CENPALAB, Cuba). This is a highly differentiated, hormone-dependent tumor line, with a replication time, (VDT) of English, (volume doublimng time) of 17 days.
- VDT replication time
- the tumors were routinely measured once a week.
- the tumor volume was calculated using the formula 4/3 ⁇ r 3 where r is the mean of the radius.
- the animals were kept on a commercial diet and fresh water at libitum.
- Treatment of animals The treatment of animals was carried out using a therapeutic model, in which fragments of the Dunning R3327-H tumor line were inoculated, as described in section 3.1.1. The therapeutic intervention (immunizations), began when the tumors
- I O reached a diameter of approximately 10 mm. Immunizations were performed with a biweekly interval.
