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.

Disclosed herein are methods for selecting cancer patients for autologous cancer vaccine therapy and methods for predicting survival of cancer patients after autologous cancer vaccine therapy comprising, measuring the level of soluble programmed cell death protein-1 (sPD-1) in the blood of the patient.

The compositions described herein include an epitope of a peptide that may elicit an immune response in a subject following administration. The compositions may comprise nucleic acids. The compositions may comprise peptides. The methods described herein include administering a composition comprising an epitope of a peptide to a subject in need thereof.

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.

The disclosure provides CARs (CARs) that specifically bind to CD70. The disclosure further relates to engineered immune cells comprising such CARs, CAR-encoding nucleic acids, and methods of making such CARs, engineered immune cells, and nucleic acids. The disclosure further relates to therapeutic methods for use of these CARs and engineered immune cells comprising these CARs for the treatment of a condition associated with malignant cells expressing CD70 (e.g., cancer).

The invention provides improved compositions for adoptive cell therapies for cancers that express CD79B. The present invention relates to improved compositions and methods for treating cancer. More particularly, the invention relates to improved anti-CD79B chimeric antigen receptors (CARs), genetically modified immune effector cells, and use of these compositions to effectively treat CD79B expressing cancers.

Provided herein, in some embodiments, are methods and compositions (e.g., cell compositions) for the treatment of cancer, such as CD33.sup.+ malignancies.

D domain (DD) containing polypeptides (DDpp) that specifically bind targets of interest (e.g., BCMA, CD123, CS1, HER2, AFP, and AFP p26) are provided, as are nucleic acids encoding the DDpp, vectors containing the nucleic acids and host cells containing the nucleic acids and vectors. DDpp such as DDpp fusion proteins, are also provided as are methods of making and using the DDpp. Such uses include, but are not limited to diagnostic and therapeutic applications.

The present invention is based, in part, on the identification of methods of modulating PD-1 expression and/or activity in regulatory T cells (Tregs) to thereby regulate effector immune responses in effector T cells (Teffs).

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.
