Abstract: This invention reveals the pharmaceutical composition that includes the surface antigen (HBsAg) of the hepatitis B virus (HBV) and the antigen of the nucleocapsid (or core, HBcAg) of the same virus. The HBcAg of this composition contains messenger ribonucleic acid (mRNA) at a proportion of over 45% of the total amount of ribonucleic acid (RNA) in this antigen. Because of the changes in the constitution of the antigens forming it, the composition of the invention is useful for the prevention or treatment of chronic hepatitis B. It also covers the use of this pharmaceutical composition in the production of a drug for immuno-prophylaxis or immunotherapy against HBV infection, and its use to increase the immune response against an additional antigen that is co-administered with the mixture of these antigens.

Abstract: The present invention is related with the field of the therapeutic immunization, specifically with the employment of a new formulation of antigens of the Hepatitis B Virus (HBV) for the cellular stimulation. The formulation is formed by the surface antigens (HBsAg) precipitated in suspension and the nucleocapsid (HBcAg) of the HBV. The formulation contains these antigens like suspended particles of sizes less than 500 nm and higher than 500 nm, in a mixture where the proportion among the particles of the mentioned sizes is among 50%-50% and 80%-20%, respectively. The selection of a range of sizes of particles allows that the levels of stimulation of several cellular types are maximized. Additionally, a cellular stimulation method is described with this formulation, and the later passive immunization of patients with chronic Hepatitis B, based on the maximum stimulation in vivo or in vitro using heterologous or autologous cells (dendritic cells, B cells and macrophages).

Abstract: The present invention is related with the field of therapeutic vaccines against pathogens causing chronic diseases. It comprises the use in therapy of formulations containing the Hepatitis B surface antigen (HBsAg) as the main compound. The HBsAg is produced as a recombinant product in Picchia pastoris. The formulations of the present invention also comprise the combination of the Hepatitis B surface antigen and other coadministered antigens. The resulting formulations are able to generate potent lymphoprolipherative and cytotoxic responses apart from a remarkable response of specific antibodies, which make them very effective in the treatment of such diseases.
