The present invention provides phagemid vectors and associated phagemid particles for cancer treatment, and in particular, to the use of novel phagemid particles and associated expression systems for the treatment, prevention, amelioration, or management of cancer. In particular, the invention relates to the use of phagemid particles and expression systems for the delivery of transgenes encoding cytokines, for the treatment, prevention, amelioration, or management of cancer. The invention also extends to the use of phagemid particles and expression systems for the delivery of transgenes, and for the combination of such treatment with the use of adoptively transferred T cells, for the treatment, prevention, amelioration, or management of cancer.

Engineered bacteriophage and methods of forming the bacteriophage are described. Multivalent bacteriophage are described that can include multiple different exogenous polypeptides at a surface of the capsid head. Vaccines and methods of forming and using vaccines are described. A vaccine can include an engineered bacteriophage that exhibits an immunogenic exogenous polypeptide at a surface of the bacteriophage. Multivalent bacteriophage and immunogenic bacteriophage are free of nucleic acids encoding the exogenous polypeptide(s).

The present invention relates to a retroviral system for the transfer of non-viral RNA into target cells and more particularly a retroviral particle capable of delivering multiple RNAs. More particularly, it relates to retroviral particles comprising a protein derived from the Gag polyprotein an envelope protein, optionally an integrase and at least two encapsidated non-viral RNAs, the encapsidated non-viral RNAs each comprising an RNA sequence of interest linked to an encapsidation sequence, each encapsidation sequence being recognised by a binding domain introduced into the protein derived from the Gag polyprotein and/or into the integrase.

The invention concerns a modified enveloped virus wherein said virus has at least one anti-tumor, tumor-specific peptide non-genetically attached to or inserted in/through the viral envelope; a pharmaceutical composition comprising same; and a method of treating cancer using same.

An artificial AAV capsid comprising a heterologous conducting airway targeting sequence is provided. The artificial AAV is useful as a targeting moiety, for delivery of heterologous molecules which are associated therewith. The artificial AAV is also useful in the generation of AAV vectors having the artificial capsid. Also described are methods of modifying the native tropism and transduction efficiency of vectors by improving and/or ablating their ability to transduce conducting airway cells. Methods of targeting conducting airway cells and delivering therapeutic and other molecules thereto are also provided.

A method for modifying the genome of a lytic target phage, uses of the method and products thereof are described. Compositions comprising such phage are also described. The compositions may be formulated as a medicament, which are useful for human treatment and may treat various conditions, including bacterial infections.

Recombinant adenoviral vectors, immunogenic compositions thereof and their use in medicine, and methods for generating recombinant adenoviral vectors are provided. In particular, the an adenovirus vector having a capsid derived from chimpanzee adenovirus AdY25, wherein the capsid encapsidates a nucleic acid molecule comprising an exogeneous nucleotide sequence of interest are provided.

The present invention provides a genetically recombinant vaccinia virus effective in preventing or treating cancer. Specifically, the present invention provides a vaccinia virus comprising two polynucleotides, a polynucleotide encoding IL-7 and a polynucleotide encoding IL-12; a combination kit of two vaccinia viruses, a vaccinia virus comprising a polynucleotide encoding IL-7 and a vaccinia virus comprising a polynucleotide encoding IL-12; and use of the two vaccinia viruses in combination.

In one or more embodiments, the present invention provides novel artificial, non-naturally-occurring double stranded DNA segments (and related methods) capable of acting as decoy binding sites for oncogenic transcription factors and a general method for suppressing aberrant activity of oncogenic transcription factors that promote cancer progression. In various embodiments, the present invention involves the sequestration of targeted oncogenic transcription factors at these artificial, non-naturally occurring engineered transcription factor binding sites, which have been introduced into the cells using oncolytic or other viruses that can be engineered to selectively target cancer cells. These artificial, non-naturally occurring engineered transcription factor binding sites act as decoys for binding so as to competitively sequester oncogenic transcription factors away from the host genomic DNA, thus abolishing or reducing oncogenic transcription factor activity and resulting in restored sensitivity to chemotherapy, increased apoptosis, and reduced cancer cell proliferation.

The present disclosure relates to, inter alia, variants of the receptor binding domain of a coronavirus (e.g., SARS-CoV-2) having increased immunogenicity and reduced aggregation, and the use of the RBD variants in methods for preventing infection of the coronavirus.
