How does oncolytic virus therapy treatment work?

“The oncolytic virus kills tumor cells and causes the release of danger signals, which help to generate an immune response,” explained Dr. Kaufman, who co-led the clinical trial that led to the approval of T-VEC.

How are oncolytic viruses made?

Oncolytic viruses are naturally occurring or genetically modified to target specific types of cancer cells. They selectively replicate within the cancer cell via a tumor-specific promoter element that is incorporated into the viral genome or in deletions in key portions of the viral genome.

How many oncolytic viruses are approved?

There is currently one oncolytic virus therapy approved by the FDA for the treatment of cancer: T-VEC (Imlygic®): a modified herpes simplex virus (HSV) that infects tumor cells and promotes their destruction; approved for subsets of patients with melanoma.

What are the benefits of oncolytic virus therapy?

Oncolytic virus therapy aims to eradicate tumours using viruses which only infect and destroy targeted tumour cells. It is urgent to improve understanding and outcomes of this promising cancer treatment because oncolytic virus therapy could provide sensible solutions for many patients with cancer.

Is measles an oncolytic virus?

Measles virus as an oncolytic immunotherapy. Measles virus-mediated oncolysis has been shown to support different phases of the antitumor immune response: Oncolysis induces immunogenic cell death, which promotes dendritic cell activation, antigen presentation, and cross-priming of T cells.

What are oncolytic products?

2 Oncolytic products refer to replication competent viruses or dividing bacteria that are used as therapeutic agents to. mediate lysis of tumor cells.

What is virus therapy?

Virotherapy is a treatment using biotechnology to convert viruses into therapeutic agents by reprogramming viruses to treat diseases. There are three main branches of virotherapy: anti-cancer oncolytic viruses, viral vectors for gene therapy and viral immunotherapy.

Is Rigvir available in the United States?

To date, three OVs are available commercially for the treatment of cancer. These include Rigvir, approved in Latvia, Georgia, and Armenia, Oncorine H101 approved in China, and talimogene laherparepvec (T-VEC) approved in the USA.
