Compositions and methods for eradicating tumor cells using novel compositions are contemplated. In one aspect, a pharmaceutical composition comprising a CAR scaffold and an antigen binding domain in a single chimeric species is provided. In some aspects, the CAR scaffold may comprise a CD28 costimulatory signaling region and a CD3ζ activation domain or a complete CD3ζ activation domain. In some aspects, the CAR scaffold may be codon-optimized for improved expression in mammalian cell lines and/or for improved function upon transfection into natural killer (NK) or other immune cells. In further aspects, the antigen binding domain may comprise a VL and VH domain linked by a spacer and may be codon optimized. A CD64 leader sequence may be attached to the antigen binding domain, e.g., at the N-terminus of the antigen binding domain.

Embodiments are directed to fibrillar adjuvants. Epitopes assembled into nanofibers by a short synthetic fibrillization domain elicited high antibody titers in the absence of any adjuvant.

The invention relates to cancer therapeutics, in particular, the system of making cancer cells more susceptible to effector cells by introduction of cellular therapy targets into the cancer cells.

A method of treating patients suffering from cancers driven by deregulated Human Epidermal Growth Factor Receptor (HER1/Human EGFR) comprising administering to a patient in need of such treatment a flexible and active regimen for combining a tyrosine kinase inhibitor (TKI) and anti-EGF antibodies for inhibition of the pathway activated by EGF-EGFR binding (mAb). The anti-EGF antibodies can be produced by active immunization or provided passively by the administration of antibodies that are anti-EGF. The method comprises TKI administered according to a continuous regimen based on an average daily dose in the range of 10 to 150 mg and the mAb is co-administered either actively or passively according to a dosing regimen achieving a therapeutic effective amount repeated thrice, twice or once a week, once in two weeks, once in three weeks or at least once monthly.

Disclosed are means, methods and compositions of matter useful for amplification of adaptive immune responses towards neoplastic tissue. In one embodiment, immunization of a patient is performed by a means comprising of administering either an exogenous vaccine or stimulation of immunogenicity of the tumor so as to cause release of antigens/increased exposure of antigens, thus resulting in an “endogenous” vaccine. Subsequent to vaccination a patient is treated by an immunopheresis procedure, in order to allow for removal of “blocking factors” produced by the tumor or produced by cells programmed by tumors to produce said blocking factors. In one embodiment further immunization is performed subsequent to removal of said blocking factors in order to allow for enhancement of adaptive immune responses

Disclosed is a group of chimeric antigen receptors (CARs) having two, three or four CAR molecules, wherein each member of the group of CARs is different in its amino acid sequence from one another, and wherein each of the CAR molecules of the group include at least a transmembrane domain and an ectodomain, wherein the ectodomain has one or two antigen binding moieties and/or one or two binding sites to which other polypeptides each including at least an antigen binding moiety are able to bind; wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein each CAR molecule of the group includes at least one heterodimerization domain.

The present disclosure provides an adjuvant that can boost the quantitative expansion of immune cells in vivo, and a combination comprising the adjuvant and immune cells. The present disclosure also provides a cascade booster system comprising the adjuvant and modified immune cells. The present disclosure also provides a treatment method using the adjuvant and the immune cells of the present disclosure.

Provided is a ROBO1 CAR-NK cell carrying a suicide gene, and a preparation method and application thereof. In order to increase the safety and controllability of a CAR-NK therapy, on the basis of a present ROBO1 CAR-NK cell, a suicide gene switch element is integrated into a genome by means of a lentiviral transfection technology to form a CAR-NK carrying a suicide gene. By adding the suicide gene, the CAR-NK cell can be better controlled, and the clinical safety is further improved.

Some embodiments of the present disclosure are directed to methods that include delivering to a subject a nucleic acid encoding an antigen, wherein the nucleic acid is delivered via a tumor-selective vehicle or via intratumoral injection, and delivering to the subject an immune cell expressing a receptor that binds to the antigen.

The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein. It also discloses its use for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the treatment of cancer or tumour diseases. The present invention further describes a method for increasing the expression of a peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.
