The present disclosure relates to a replication deficient oncolytic viral vector or replication capable group B oncolytic adenovirus selected from the group consisting of Ad11 and enadenotucirev, wherein the virus encodes an antibody or a binding fragment thereof for expression on the surface of a cancer cell, wherein said antibody or binding fragment is specific to a CD3 protein of a T-cell receptor complex (TCR), wherein the virus does not encode a B7 protein or an active fragment thereof, pharmaceutical compositions comprising the same, and use of any one of the same in treatment, particularly in the treatment of cancer.

Group B adenovirus encoding an anti-TCR-complex antibody or fragment

The present disclosure relates to a group B adenovirus comprising a sequence of formula (I):

Oncolytic adenoviruses armed with heterologous genes

The present disclosure relates to a replication deficient oncolytic viral vector or replication capable oncolytic virus encoding an antibody or a binding fragment thereof to the antigen-specific T-cell receptor complex (TCR) for expression on the surface of a cancer cell, pharmaceutical compositions comprising the same, and use of any one of the same in treatment, particularly in the treatment of cancer.

Virus encoding an anti-TCR-complex antibody or fragment

The present disclosure provides a replication competent oncolytic adenovirus with selectivity for cancer cells, wherein the adenovirus comprises a transgene under the control of a promoter endogenous to the virus, wherein the transgene comprises a DNA sequence encoding a B7 protein or an active fragment thereof, compositions comprising same, methods of generating the viruses, and use of the viruses and compositions in treatment, particularly in the treatment of cancer.

Oncolytic adenovirus encoding a B7 protein or active fragment

The present disclosure provides a oncolytic adenovirus with selectivity for cancer cells, wherein the adenovirus comprises a transgene under the control of a promoter endogenous to the virus, wherein the transgene comprises a DNA sequence encoding a membrane anchored anti-CD3 antibody or a binding fragment thereof, compositions comprising same, methods of generating the viruses, and use of the viruses and compositions in treatment, particularly in the treatment of cancer.

Oncolytic adenovirus encoding a therapeutic protein or active fragment

The present disclosure relates to a method of making an adenovirus plasmid comprising a part or all of an adenovirus genome and one or more original restriction sites allowing rapid and flexible manipulation of the adenovirus genome, and methods of preparing adenovirus constructs, for example comprising a transgene. The disclosure also extends to novel intermediates employed in and generated by the method, to plasmids and shuttle vectors of the method and to adenoviruses or adenoviral vectors obtainable from the plasmid and/or method. The disclosure further relates to use of the viruses or vectors, for example obtained from a method disclosed herein, in therapy, such as use in the treatment of cancer.

Method of making adenovirus and corresponding plasmids

The present disclosure relates to a type B adenovirus wherein E4orf4 is deleted or non-functional and generally having a DNA sequence in the E3 region, in particular viruses of formula (I), compositions containing the virus, for example pharmaceutical formulations of the virus, processes for making the viruses and the compositions and use of any one of the same in treatment, particularly in the treatment of cancer, such as colorectal cancer and ovarian cancer.5'ITR-B-B-B-B-B-B-B-3&#x2032;ITR&#x2003;&#x2003;(I).

Group B adenovirus modified in the E4orf4 region

The present disclosure relates to a group B adenovirus comprising a sequence of formula (I): 5'ITR-B1-BAB2-BX-BB-BY-B3-3&#x2032;ITR wherein: B1 is bond or comprises: E1A, E1B or E1AE1B; BA comprises: E2B-L1-L2-L3-E2A-L4; B2 is a bond or comprises: E3; BX is a bond or a DNA sequence comprising: a restriction site, one or more transgenes or both; BB comprises L5; BY is a bond or a DNA sequence comprising: a restriction site, one or more transgenes or both; B3 is a bond or comprises: E4; wherein at least one of BX or BY is not a bond, pharmaceutical compositions comprising the same and use of the viruses and compositions in treatment, particularly in the treatment of cancer. The disclosure also extends to plasmids and processes employed to prepare the said viruses.
