The present invention provides methods for treating an individual having solid or lymphatic tumor comprising locally administering to the site of the tumor an oncolytic virus, and systemically administering an immunomodulator (including a combination of immunomodulators). The methods may further comprise local administration to the site of the tumor a second immunomodulator (including a combination of immunomodulators). Also provided are compositions and kits for the cancer therapy methods.

Recombinant adenovirus genomes that include a synthetic transcriptional circuit are described. Synthetic adenoviruses positively regulated using two-step transcriptional amplification (TSTA) are further described. Selection of the heterologous promoter is based on the desired replication characteristics of the synthetic virus. For example, the heterologous promoter can be a constitutive promoter, a tumor-specific promoter or a tissue-specific promoter.

The present invention provides methods for treating an individual having solid or lymphatic tumor comprising locally administering to the site of the tumor an oncolytic virus, and systemically administering an immunomodulator (including a combination of immunomodulators). The methods may further comprise local administration to the site of the tumor a second immunomodulator (including a combination of immunomodulators). Also provided are compositions and kits for the cancer therapy methods.

Provided herein are methods and related compositions for administering viral transfer vectors and antigen-presenting cell targeted immunosuppressants.

The present invention provides methods for treating an individual having bladder cancer comprising intravesically administering to the individual an oncolytic virus. Also provided are pharmaceutical compositions and kits for treating bladder cancer.

Modified E1a regulatory sequences are provided, wherein at least one Pea3 binding site, or a functional portion thereof, is deleted. Also provided are modified E1a sequences that selectively express particular isoforms. Also provided is an E1b-19K clone insertion site. These modified sequences can be used individually, or in combination with one another, to provide tumor-selective expression of proteins.

Provided herein are methods of treating cancer by activating resident memory T cells using one or more antigenic peptides.

To increase the therapeutic potential of these oncolytic viruses based on a 24 base pair deletion in the viral E1 A gene (D24), a conditionally replicating adenovirus targeting multiple receptors upregulated on tumors was generated by incorporating an Ad5/3 fiber with a carboxyl terminus RGD ligand. The virus displayed full cytopathic effect in tumor lines assayed at low titers with improved cytotoxicity over Ad5-RGD D24, Ad5/3 D24 and an HSV oncolytic virus. The virus was further engineered to deliver immunotherapeutic agents such as GMCSF while maintaining enhanced heterogenic oncolysis.

Provided are an LncRNA and oncolytic adenovirus, and application thereof. The oncolytic adenovirus is used as a carrier to express the LncRNA, so as to express the LncRNA in a cancer cell; competitively binding a target gene of OncomiRs, and consuming the OncomiRs, thus protecting a cancer suppressor gene from interference and suppression of the OncomiRs, and achieving target intervention therapy of the cancer cell.

The present disclosure provides a method of treating a human patient comprising the steps of: systemically administering multiple doses of a parenteral formulation of a replication capable oncolytic adenovirus of subgroup B in a single treatment cycle, wherein the total dose given in each dose is in the range of 1×10.sup.10 to 1×10.sup.14 viral particles, and wherein each dose of virus is administered over a period of 1 to 90 minutes, for example at a rate of viral particle delivery in the range of 2×10.sup.10 particles per minute to 2×10.sup.12 particles per minute. The disclosure further extends to formulations of the said oncolytic adenoviruses and combination therapies of the viruses and formulations with other therapeutic agents.
