  • Publication number: 20200171151
    Abstract: The invention discloses a novel tumor-specific complete vaccine system generated in-vivo. This vaccine system is developed by the use of separated tumor cells inactivated by irradiation and the in-vivo interaction with an oncolytic viral vector with transgenic expression of GM-CSF, completed with immune checkpoint modulators (“ICM”) such as co-stimulatory signals confirmation with an anti-CTLA4 antibody. Specifically there will be no pre-incubation or interaction of the either two or all three components before administration to the patient. One of such oncolytic viral vector examples is CG0070 (GM-CSP expressing conditionally replication competent adenovirus). Mixing of the tumor-viral-ICM components will take place just prior to administration to preserve the effects of the oncolytic process and subsequent immunotherapeutic responses to be live and in vivo from the very first beginning. This invention is a complete live and in-vivo cancer vaccine system (“CLIVS”).

  • Publication number: 20120082687
    Abstract: Disclosed is a method to recover an antigen presenting cells (APCs) and immune cells rich mixture (AIM) from peripheral blood mononuclear cells (PBMC) mobilized with one or more cell adhesion inhibitors for the preparation of an AIM vaccine or an AIM adoptive immunotherapy preparation. In addition, AIM mobilization can be enhanced by priming, simultaneously or in sequence, one or more of a combination of different chemical compounds, cytokines, hormones, growth factors, etc. The interaction of chemokines and chemokine receptors enable tumor cells attachment or in close proximity to antigen presenting cells and immune cells which possess similar receptors in a micro niche environment. Severing the chemokine/chemokine receptor linkage by a cell adhesion inhibitor will release these specifically primed cell mixtures into the peripheral blood. The collection of these cells from the peripheral blood has never been described and is the basis of this invention.

  • Publication number: 20110250687
    Abstract: Disclosed is a method to recover a dendritic cell rich mixture from peripheral blood mononuclear cells (PBMC) mobilized with one or more cell adhesion inhibitors (CAI) for the preparation of a dendritic cell vaccine. The CAI derived dendritic cell rich mixture (CdDC) from PBMC can either be used alone or better still, be induced into dendritic vaccine specific preparations with the addition or modification with different antigens and methodologies of immunological induction methods known to the art. These CAI derived dendritic vaccines can then be used, but not exclusively so, in the treatment of cancer and infectious diseases. In order to achieve the best immature and mature dendritic cell rich mixture, peripheral blood cells mobilization may be achieved by administering, simultaneously or in sequence, to an individual one or more of a combination of different chemical compounds, hormones, growth factors etc. prior to PBMC collection with one or more of cell adhesion inhibitors such as a CXCR4 antagonist.

  • Publication number: 20100226894
    Abstract: Disclosed is a method to recover a mixture cell population consisting of a complete profile of progenitor cells including embryonic like stem cells (a “complete progenitor cell mixture” or CPM) from the peripheral blood of an individual by administering to that individual a combination of at least one or more from the category of growth factors and hormones combining with at least one or more from the category of cell fusion inhibitor compounds, and then recovering peripheral blood progenitor cells from said individual. The hormones and growth factors group should include hGH (human growth hormone) with or without erythropoietin (EPO), but specifically without either G-CSF or GM-CSF. The cell fusion inhibitor group should include a CXCR4 antagonist. Also disclosed is a method for using or preserving such a complete progenitor cells mixture (CPM) for the treatment of diseases.

  • Publication number: 20060178327
    Abstract: The use of specially selected sequences from the target gene into designing double stranded or other forms of RNA (siRNA precursors or siRNAp) that enables small interfering RNA (siRNA) from this new invention is delivered for inhibition of cellular gene expression. Diseases may be prevented and treated by this process, e.g. Severe Acute Respiratory Syndrome (SARS) and Human Immunodeficiency Virus (HIV) infections. The process may be practiced in vivo or in vitro. The small interfering RNA enabled is of sequences usually of 23 nucleotides or less. The invented method of sequence selection from the target gene, however, may be applicable to double stranded RNA of any length.

  • Publication number: 20050164252
    Abstract: This invention provides the use of conserved non-genic sequences so commonly found in most species of plants and animals for the detection of a disease and condition. The intimate and ultimately important link of the corresponding DNA sequences and expressed RNA sequences with their conserved non-genic sequence makes the detection possible. Apart from the diagnostic use, the combination of the conserved non-genic sequences with the corrected or designed DNA or RNA sequences makes treatment or improvement possible for living organisms.

  • Publication number: 20030021749
    Abstract: Fluorine-18, fluorine-18-incorporating radiopharmaceuticals (FRPs), and other positron-emitting isotopes and radiopharmaceuticals have been used for diagnostic purposes in positron emission tomography (PET). This invention describes the therapeutic use of positron-emitting radiopharmaceuticals such as FRPs primarily, but not exclusively, for the treatment of cancer and cancer-related illnesses. The radiopharmaceuticals are administered in dosages significantly higher than those used for diagnostic imaging.
