摘要:
The present invention describes a pharmaceutical composition whose active ingredient includes conjugates of membrane vesicles of Neisseria meningitidis and the GM3 ganglioside in a conjugation ratio in excess of proteins, has particular characteristics of size, surface charge and a morphology associated with nano-particulate systems that give it advantageous properties as an immunomodulator, because it induces a convenient and significant reduction of myeloid-derived suppressor cells that has an impact on the response of T lymphocytes and on the survival of patients with tumors. The invention further discloses the use of the pharmaceutical composition disclosed in the treatment of cancer, particularly those cancers where the myeloid-derived suppressor cells (MDSCs) are high; as well as a method of treatment with said composition in cancer patients and a method to select those who will receive said treatment.

The present invention relates to the field of Biotechnology and more particularly to the mutated polypeptides of TGFβ molecule whose primary sequence has a high homology with the sequence of human TGFβ. These muteins lose their ability to interact with ALK5 but maintain their ability to interact with other receptors that are part of the receptor complex (TβRII and TβRIII). They have the property of antagonizing the signaling of all natural variants of TGFβ ligands, dependent of ALK5 recruitment in the receptor complex, and have significant immunomodulatory effects. The present invention relates to pharmaceutical compositions comprising as active principle the polypeptides or fusion proteins disclosed and their use thereof given their modulating effect on the immune system in diseases such as cancer, diseases accompanied by fibrosis and chronic infectious diseases.

The present invention relates to the branch of Biotechnology and Medicine, particularly to a method for the selection and treatment of patients with carcinomas of epithelial origin that co-express the HER1 and HER2 receptors without increased expression of these receptors or with the presence of RAS activating mutations. In particular, this method is based on the application of bivalent vaccine compositions which have as active principle the extracellular domains of the HER1 and HER2 receptors or portions thereof and as an adjuvant the very small proteoliposomes derived from the outer membrane proteins of Neisseria meningitidis and the GM3 ganglioside. This method is useful for the treatment of patients whose expression levels of HER1 and HER2 do not allow the monoclonal antibodies against HER1 and/or HER2 to have a therapeutic effect.

摘要:
The invention describes vaccine compositions combined in the same proportion with the extracellular domains of growth factor receptors Her1 and Her2 or fragments thereof and furthermore very small size proteoliposomes derived from proteins of the outer membrane of Neisseria meningitidis and GM3 ganglioside (VSSP-GM3), administered subcutaneously. The disclosed compositions, which induce the production of antibodies are used for the treatment of malignancies and offer advantages because they completely remove the tumor mass thus preventing tumor regression due to the emergence of resistant variants.
摘要:
The present invention relates to a humanized IgG1 isotype anti-CD6 antibody (T1h) that binds to the Scavenger receptor cysteine-rich (SRCR) domain 1 (D1) of CD6 present on the surface of thymic epithelial cells, monocytes, activated T cells and a variety of other cells types.
摘要:
Provided is a method for obtaining high-yield, stable expression cell clones from myeloma cell lines in a protein-free culture medium. The method is used for industrial production of a recombinant antibody, and includes three stage: (1) adapting to a protein-free culture medium, statically culturing cells at a low density, and gradually reducing a fat-rich supplement to a chemical culture medium; (2) adapting to a protein-free culture medium; culturing cells at a high density, and using a perfusion fermentation system in a laboratory scale; and (3) screening high-yield, stable expression cell clones from the cells after fermentation ends. The cell clone may be used to produce a humanized anti-NeuGcGM3 14F7 recombinant antibody.
摘要:
The present invention discloses a conjugate comprising erythropoietin (EPO) and an asymmetric branched polymeric structure comprising two branches of monomethoxypolyethylene glycol (mPEG), where the molecular mass of one of these mPEG branches is between 10 kDa and 14 kDa, and the molecular mass of the other branch of mPEG is between 17 kDa and 23 kDa, as well as the pharmaceutical compositions containing it. The invention also provides a method for the preparation of pegylated EPO, wherein said protein is conjugated to an asymmetric branched polymeric structure with two branches of mPEG having the above described molecular masses.
摘要:
The present invention relates to pharmaceutical compositions for the treatment of malignant tumors. Particularly those tumors that express EGFR and GM3 N-glycolyl ganglioside targets to enhance the therapeutic effect produced by separated therapies against these targets. The pharmaceutical compositions of the invention include antibodies and/or vaccines against each of the targets. Additionally the present invention relates to methods for applying the compositions of the invention.
