Definitions
- the present invention is related to the branch of immunology and viral vaccines, particularly with recombinant avian smallpox virus for protein combinations based on hepatitis C virus (HCV) antigens and pharmaceutical compositions capable of inducing a cellular immune response against HCV.
- HCV hepatitis C virus
- HCV is first identified in 1989, through the use of molecular biology techniques, as the main causative agent of post-transfusion hepatitis No-A, Non-B (Choo QL., Kuo G., et al. ( 1989) Isolation of a cDNA clone derived from a blood-borne non-A, non-B viral hepatitis genome. Science. 244: 359-62; EP0318216 Chiron Corp). There are currently more than 170 million people infected by this viral agent in the world. 85% of HCV infections are persistent, often causing cirrhosis and hepatocellular carcinoma (Caselmann WH, AIt M.
- Recombinant live vectors are attractive candidates for generating a cellular immune response against HCV.
- Immunization with recombinant adenovirus for the capsid and E1 in mice induced a specific cytotoxic T type response against these antigens (Bru ⁇ a-Romero O., et al. (1997) Induction of cytotoxic T-cell response against hepatitis C structural antigens virus using a defective recombinant adenovirus Hepatology 25: 470-7).
- a-Romero O., et al. 1997 Induction of cytotoxic T-cell response against hepatitis C structural antigens virus using a defective recombinant adenovirus Hepatology 25: 470-7.
- This group of viruses also includes avian smallpox virus (WA), whose use for the induction of immune response has not been previously reported for HCV antigens.
- Avian smallpox virus does not replicate in mammalian cells, but it can infect and efficiently express the proteins encoded by its genome in the cytoplasm. Due to these characteristics, the regulatory risks related to employment in humans is much lower than in other viral variants.
- This invention overcoming the limitations and prior art, solves the aforementioned problem by providing a recombinant avian smallpox virus which contains DNA fragments derived from the hepatitis C virus in a non-essential region of the WA genome, capable of inducing a specific cellular response against HCV depending on the amino acid regions from the HCV antigens contained in the protein expressed by the WA.
- the FPCoEI virus expresses a protein comprising aa 79-338 (SEQ ID No: 1) that includes part of the protein of the capsid and E1 and the FPBS virus comprises a chimeric protein (SEQ ID No : 2) that includes specific epitopes for both CD4 + and CD8 + T cells corresponding to different HCV antigens.
- the coding sequence for the HCV antigens comes from the cDNA from a Cuban isolation of HCV (Morales J, et al. WO 98/25960).
- Another aspect of the present invention relates to a pharmaceutical composition for inducing specific cellular immune response against HCV in subjects.
- composition comprises an effective immunizing amount of recombinant avian smallpox virus and a pharmaceutically acceptable excipient.
- the avian smallpox viruses that make up the invention have the ability to penetrate human cells and express HCV antigens in their cytoplasm. The expression in human cells is directed by the transcriptional unit, composed of a synthetic immediate / early promoter for WA. These viruses also contain the xanthine guanosine phosphoribosyl transferase gene under the control of the 7.5K vaccinia promoter. These viruses have no ability to replicate in humans.
- This composition can be administered intramuscularly, intraperitoneally or subcutaneously.
- the method of administration may be by syringes, gene gun, spray or other administration devices. Each individual receives a dose ranging from 2.5 x 10 7 to 1 x 10 8 PFU / dose in a given volume.
- WAs can also be administered in alternate schemes with proteins or other recombinant viruses for HCV antigens, or in parallel schemes with cytokines and other immunomodulatory compounds. These combinations allow the appearance of new epitopic specificities or the potentiation of some branch of the particular immune response.
- the pharmaceutical composition of the present invention can be administered to induce immunity against HCV before, simultaneously or after another therapy or vaccine, also to induce preventive immunity against HCV infection and to induce immunity against HCV in patients with chronic hepatitis C, cirrhosis and liver cancer.

- Hepatitis C Virus As understood in this invention, the terms Hepatitis C Virus or HCV describe the virus in a generic manner, so that the terms are not limiting to a particular HCV viral sequence or isolation.
- a coding sequence is understood as a nucleic acid molecule which is translated into a polypeptide, usually via mRNA, when placed under the control of an appropriate regulatory sequence.
- a coding sequence may include, but is not limiting for cDNA and recombinant nucleotide sequences.
- Example 1 Evaluation of FPCoEIc, FPCoEI, and FPBS viruses
- FIG. 1 shows a schematic representation of the sequence corresponding to HCV antigens.
- the virus were obtained as follows. Chicken fibroblasts were infected with WA and subsequently transfected with pFPCoElc, pFPCoEl or pFPBS plasmids using lipofectamine (Invitrogen, USA). These plasmids are derived from plasmid pFP67xgpt (Vázquez-Blomquist D., González S., Duarte CA.
- the viral product of an infection plate was then amplified and the presence of the HCV-corresponding insert was confirmed by polymerase chain reaction.
- the immunogenicity of the FPCoEIc, FPCoEI and FPBS viruses in female BALB / c mice of 8 weeks was analyzed, after administering 2 doses of 2.5x10 7 PFU intraperitoneally with a 3 week interval between them.
- the immunization groups were composed of 10 animals.
- Figure 2A shows that only the immunization with FPCoEI was able to induce detectable levels of antibodies against Core and El
- Figure 2B shows the induction of a positive response of IFN-gamma secreting lymphocytes in animals immunized with FPCoEI and the FPBS, statistically superior (Student's T-test, p ⁇ 0.05) to that detected in animals immunized with the negative virus (FP9). Immunization with the FPCoEIc did not induce a positive response of IFN-gamma secreting lymphocytes.
- the animals of the groups immunized with the FPCoEI and FPBS viruses were able to significantly reduce (Student's T-test, p ⁇ 0.05) the viral load in ovaries after challenge with 10 6 PFU of a recombinant vaccinia virus (vvRE) for the antigens of the HCV structural region (aa 1-650 of the viral polyprotein) in relation to that observed after the challenge with the non-recombinant vaccinia virus for HCV antigens (WR).
- vvRE recombinant vaccinia virus
- the viral load of vvRE in animals immunized with FPCoEI and FPBS was statistically lower than that detected in animals immunized with FP9 negative smallpox virus (Student's T-Test, p ⁇ 0.05). Immunization with the FPCoEIc did not significantly reduce Ia viral load in ovaries.
- the challenge with vaccinia virus was performed intraperitoneally, 2 weeks after the last immunization with the smallpox virus. The ovaries were removed 5 days after the vvRE inoculated.
- the challenge assay with recombinant vaccinia virus has been extensively evaluated to demonstrate the ability of a vaccine candidate to induce a strong cellular response in vivo. Particularly, the reduction of the viral titer in ovaries is fundamentally related to the induction of a strong response of CD8 + T cells.
- Example 2 VVA administration routes (intraperitoneal, subcutaneous and intramuscular)
- Example 3 Dose comparison (0.9x10 7 , 2.5x10 7 , 5x10 7 , 1x10 8 )
- mice Female BALB / c mice were immunized intramuscularly at weeks 0 and 3 with different amounts of the recombinant viruses.
- the immunization groups were composed of 10 animals. As can be seen in Figure 4, animals immunized with 0.9x10 7 PFU did not have significant differences between the viral load detected in the ovaries of vvRE after the challenge with 10 6 PFU of this vaccinia virus, 2 weeks after the last immunization with the avian smallpox virus.
- mice of 8 weeks were immunized.
- the immunization groups were composed of 10 animals.
- One group (Co- plDKE2) was immunized intramuscularly at week 0, 3, 7 and 12 with a mixture of 100 ⁇ g of a plasmid expressing the first 650 aa of HCV polyprotein, plDKE2 (Due ⁇ as-Carrera S. , et al. (2004).
- a group of animals (pAEC-K6) was immunized under similar conditions with the negative control plasmid pAEC-K6 (Herrera AM, et al. (2000). A family of compact plasmid vectors for DNA immunization in humans. Biochem. Biophys. Res Commun. 279: 548-51). Another group was immunized with 2.5x10 7 PFU of the FPCoEI intramuscularly at weeks 0 and 3. Animals were also immunized with FP9 negative control avian smallpox virus under the same conditions.
- the lowest average viral load value was detected in animals immunized with CoPDKE2 in the first 2 doses and FPCoEI in the other 2.
- the viral challenge was performed by intraperitoneal inoculation of 10 6 PFU of vvRE, 2 weeks after The last dose with avian smallpox viruses. The ovaries were removed 5 days after the vvRE inoculated.
