CELL DEATH INDUCING CHIMERIC ANTIGEN RECEPTORS
The invention relates to cell death inducing chimeric antigen receptors (D-CAR). In particular, the present invention relates to cell death inducing chimeric antigen receptors which comprise at least one death domain in their endodomain, including cell death inducing chimeric antigen receptors comprising within their death domains modifications which attenuate the self-association and/or binding to pro-apoptotic or pro-necrotic adaptor proteins, such as FADD or TRADD. Moreover, the present invention relates to an engineered immune cell expressing at its surface a cell death inducing CAR of the present invention and, optionally, an activating chimeric antigen receptor, wherein the extracellular ligand-binding domains of the cell death inducing CAR and the activating CAR bind to different antigens. The engineered immune cell may furthermore comprise at least one edited (e.g., inactivated) gene selected from TCR genes, immune check point genes, genes involved in drug resistance, and combinations thereof.
CD47-CAR-T CELLS
The present invention provides a chimeric antigen receptor (CAR) fusion protein comprising from N-terminus to C-terminus: (i) a single-chain variable fragment (scFv) comprising V.sub.H and V.sub.L, wherein scFv has an activity against CD47, (ii) a transmembrane domain, (iii) at least one co-stimulatory domains, and (iv) an activating domain. In one embodiment, the scFv is derived from a humanized anti-CD47 antibody. The present invention also provides T cells modified to express the CAR of the present invention.
ACTIVITY-INDUCIBLE FUSION PROTEINS HAVING A HEAT SHOCK PROTEIN 90 BINDING DOMAIN
Activity-inducible fusion proteins whose activity is post-translationally regulated utilizing a hsp90 binding domain and a drug molecule are described. In the absence of the drug molecule, the activity-inducible fusion proteins are inactivated but can be activated by a relevant physiological parameter in the presence of the drug molecule. Examples of the activity-inducible fusion proteins include chimeric antigen receptors (CAR) wherein the relevant physiological parameter is antigen binding.
Highly Potent M-CENK Cells And Methods
Memory-like cytokine enhanced NK (M-CENK) cells have superior cytotoxicity and can be generated/expanded from a single batch of mononuclear cells to in sufficient quantities to so form a cell-based therapeutic suitable for infusion. Advantageously, the M-CENK cells can be cryopreserved and thawed without compromising viability and cytotoxicity.
LOW INTENSITY ULTRASOUND COMBINATION CANCER THERAPIES
Provided herein are compositions, such as, for example, CXCL 10-secreting antigen presenting cells, and methods for ultrasound-induced blood-brain bander disruption (e.g., low-intensity pulsed ultrasound (LIPU)) to treat a brain cancer in a mammalian subject.
TREATMENT OF CANCER USING HUMANIZED ANTI-EGFRVIII CHIMERIC ANTIGEN RECEPTOR
The invention provides compositions and methods for treating diseases associated with expression of EGFRvIII. The invention also relates to chimeric antigen receptor (CAR) specific to EGFRvIII, vectors encoding the same, and recombinant T cells comprising the anti-EGFRvIII CAR. The invention also includes methods of administering a genetically modified T cell expressing a CAR that comprises an anti-EGFRvIII binding domain.
Delivery methods and compositions for nuclease-mediated genome engineering
The present disclosure is in the field of genome engineering, particularly targeted modification of the genome of a cell.
Compositions and methods for treating cancer with anti-CD33 immunotherapy
Chimeric antigen receptors containing CD33 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.
COMPOSITIONS AND METHODS TO REDUCE THERAPEUTIC T CELL TOXICITY
Disclosed are off-the-shelf immune effector cells that are engineered to express anti-CD3 antibodies disclosed herein that are configured to autoactivate the immune effector cells, thereby decreasing expression of T cell receptors (e.g. TCR??) that could result in GVHD. Also disclosed are methods for modifying donor immune effector cells to make them suitable for off-the-shelf treatment of allogeneic subjects. These methods involve engineering the cells to express an anti-CD3 antibody configured to activate the cells. In some embodiments, the antibody is a bi-specific antibody that binds the CD3 complex on the immune effector cells. In other embodiments, the antibody is a membrane bound anti-CD3 antibody that autoactivates the immune effector cell.
ANTIGEN-SPECIFIC T CELLS, METHODS OF PRODUCING THE SAME, AND USES THEREOF
Disclosed herein are methods of producing tumor antigen-specific T cells and uses thereof. In the present method, peripheral blood mononuclear cells (PBMCs) isolated from a subject are cultivated with bi-specific antibodies (BsAbs) in a culture medium so as to produce the tumor antigen-specific T cells from the PBMCs. Also provided in the present disclosure are tumor antigen-specific T cells produced by the present method, and uses thereof in treating subjects suffering from cancers.
