20230096433 · 2023-03-30 · ·

Contemplated compositions and methods generate a durable immune synapse and so lead to activated T-cells and memory T-cell formation by use of selected co-stimulatory receptors and their ligands in conjunction with selected neoepitopes. Moreover, immune competent cells are attracted into a tumor microenvironment after activation of the T-cells using hybrid or chimeric binding proteins that comprise a chemokine portion and that target components of necrotic cells.

Methods of treating cancer with placenta growth factor peptide linked to immunotherapeutic antibodies

The methods and compositions described herein address the need in the art by providing compositions and methods for a therapy with an antibody that is specifically targeted to and/or retained intra- or peri-tumorally, limiting systemic exposure and reducing side-effects. Accordingly, aspects of the disclosure relate to a composition comprising an immunotherapeutic antibody operatively linked to an extracellular matrix (ECM)-affinity peptide. An ECM-affinity peptide is one that has affinity for an extracellular matrix protein.

ANAPLASTIC LYMPHOMA KINASE CHIMERIC ANTIGEN RECEPTORS AND METHODS OF USE

Provided herein are anaplastic lymphoma kinase chimeric antigen receptors (ALK CARs). The invention also provides polynucleotides encoding ALK CARs, engineered immune cells comprising an ALK CAR, pharmaceutical compositions thereof, and kits for administering the same. Methods of treating a subject with a disease by administering the ALK CAR or engineered immune cell comprising an ALK CAR, or pharmaceutical compositions thereof, are also provided.

COMPOSITIONS AND METHODS FOR DELIVERY OF NUCLEIC ACIDS TO CELLS
20230032060 · 2023-02-02 · ·

Compositions and methods of use thereof for delivering nucleic acid cargo into cells are provided. The compositions typically include (a) a 3E10 monoclonal antibody or an antigen binding, cell-penetrating fragment thereof; a monovalent, divalent, or multivalent single chain variable fragment (scFv); or a diabody; or humanized form or variant thereof, and (b) a nucleic acid cargo including, for example, a nucleic acid encoding a polypeptide, a functional nucleic acid, a nucleic acid encoding a functional nucleic acid, or a combination thereof. Elements (a) and (b) are typically non-covalently linked to form a complex.

ACTIVATABLE MONOMERIC CYTOKINE-SINGLE CHAIN (SC) FC FUSION PROTEINS AND USES THEREOF
20230035308 · 2023-02-02 ·

The present invention includes compositions and methods for making and using the next generation of activatable pro-cytokine drugs by using a single-chain fragment crystallizable (Fc) region. This single-chain Fc fusion protein is engineered according to the formulas: P1-L-Fc-L-P2-L-Fc, or P1-L-Fc-L-P2-L-Fc-L-P3 in a linear sequence from amino- to carboxy-terminus, wherein protein (P) is the biologically active moiety, e.g., an antibody, or an antigen-binding fragment, or a cytokine receptor, or a cytokine, or a fusion protein consisting of above-mentioned components; L is optional and a protease cleavable, or non-cleavable linker (up to 50-mers amino acids) that is processed by enzymes enriched in tumor tissues, wherein P1, P2, and P3 are different biologically active moieties, but at least one of them is a cytokine that forms an intramolecular heterodimer. Processing the cleavable linker by tumor-specific enzymes serves as a switch to activate the cytokine in the tumor microenvironment.

METHODS FOR WOUND HEALING
20230093013 · 2023-03-23 ·

The invention relates to plasmids capable of expressing a protein targeting immune cells when transformed into a lactic acid bacterial cell, wherein the protein is chosen from the group consisting of murine and human CXCL12 1α; CXCL17 and Ym1. The invention further relates to lactic acid bacteria transformed with a said plasmid, as well as the use of said lactic acid bacteria for wound healing in humans and animals.

ANTIBODIES AND CHIMERIC ANTIGEN RECEPTORS TARGETING GLYPICAN-3 (GPC3) AND METHODS OF USE THEREOF

Provided are anti-glypican-3 (GPC3) antibodies or antigen binding fragments thereof, and a chimeric antigen receptor (CAR) that binds glypican-3 (GPC3) containing an anti-GPC3 antibody in an extracellular domain, a transmembrane domain, and an intracellular signaling domain. Immune effector cells transduced with the disclosed CAR constructs can be used for cancer immunotherapy.

REPLICATION COMPETENT ATTENUATED VACCINIA VIRUSES WITH DELETION OF THYMIDINE KINASE WITH AND WITHOUT THE EXPRESSION OF HUMAN FLT3L OR GM-CSF FOR CANCER IMMUNOTHERAPY

The present invention relates generally to the fields of oncology, virology and immunotherapy. More particularly, it concerns the use of poxviruses, specifically the replication competent attenuated vaccinia virus with deletion of thymidine kinase (VC-TK.sup.−) with and without the expression of human Flt3L or GM-CSF as oncolytic and immunotherapy. The foregoing poxviruses can also be used in combination with immune checkpoint blocking agents. The foregoing poxviruses can also be inactivated via Heat or UV-treatment and the inactivated virus can be used as immunotherapy either alone or in combination with immune checkpoint blocking agents.
