Abstract: The present invention is related to the fields of Biotechnology and Medicine. Particularly, it describes the use of epidermal growth factor (EGF) deprivation agents that contribute to lowering and/or depleting serum epidermal growth factor levels, which has implications in the treatment of the chronic obstructive pulmonary disease. These agents can be vaccine compositions comprising as active principle the conjugate between recombinant human EGF and a carrier protein.

Abstract: The present invention provides the use of anti-CD6 antibodies that specifically bind to domain 1 of CD6 for treating effects of a coronavirus or bacterial agent and particularly COVID-19 and variants thereof. The anti-CD6 antibodies of the present invention exhibit therapeutic activity by reducing the overactive immune response, such as the high expression levels of cytokines.

Abstract: A vaccine composition for therapeutic use thereof on cancer patients includes a chemical conjugate of human recombining Epidermic Growth Factor (hrEGF) and a combining protein P64k for performing a conjugation reaction which produces said chemical conjugate in a controlled and reproducible manner. The preferred conjugate surprisingly increases the immunogenic activity causing significant increases in the anti-EGF antibody titers in humans, and provides a vaccine preparation with more than one type of effective dose presentation which enables the immunization dose per patient to be increased, but without involving an increase in immunization frequency and/or the number of immunization sites.

Abstract: The present invention concerns the biotechnology sector and more specifically human healthcare. In particular, the present invention describes a vaccine composition for therapeutic use thereof on cancer patients. The vaccine composition described in the present invention has as active principle a chemical conjugate of human recombining Epidermic Growth Factor (hrEGF) and are combining protein P64k. In addition, specific conditions are described for performing a conjugation reaction which produces said chemical conjugate in a controlled and reproducible manner. In another embodiment, the present invention concerns a method for purification of the chemical conjugate which not only provides greater purity for the therapeutic composition, but surprisingly increases the immunogenic activity causing significant increases in the anti-EGF antibody titers in humans.

Abstract: The present invention relates to the biotechnological field and particularly to the human health. More particularly, the present invention relates to a vaccine composition for therapeutic use in cancer patients. The vaccine composition of the present invention has as active principle a chemical conjugated between the human recombinant Epidermal Growth Factor (hrEGF) and the P64K recombinant protein. In another embodiment, the present invention relates to the conjugation procedure to obtain, a chemical conjugated under controlled and reproducible parameters. In a preferred embodiment, the present invention relates to the procedure for purifying the chemical conjugated with a higher purity of the therapeutical vaccine composition, and a surprisingly increased immunogenic activity, inducing a significant increase of the anti-EGF antibody titers in humans.
