The U.S. Food and Drug Administration approved Imlygic (talimogene laherparepvec) on 27th October 2015, the first FDA-approved oncolytic virus therapy, for the treatment of melanoma lesions in the skin and lymph nodes. Imlygic/talimogene laherparepvec is an oncolytic viral treatment. It’s a genetically altered herpes virus that is injected specifically into the melanoma tumors. It is thought to work by multiplying inside the cancerous cells and killing them, in addition by making alterations in the immunity system of the body to attack the cancer cells.
Melanoma is a serious disease that can progress and spread to different parts of the body, where it gets to be hard to treat. Imlygic is used to treat melanoma sores that can’t be uprooted completely by surgery. Melanoma is one of the types of skin cancer that is described by the uncontrolled growth of melanocytes, which are the cells responsible for giving the pigment to skin.
Imlygic (Talimogene Laherparepvec) mechamism for melanoma treatment
Imlygic is a hereditarily altered herpes simplex infection type 1 intended to repeat inside tumors and produce an immunostimulatory protein called granulocyte-macrophage colony stimulating element (GM-CSF). Imlygic causes cell lysis, or death, which bursts tumors, discharging tumor derived antigens, which along with GM-CSF, may advance an anti-tumor immune response.
A treatment course with Imlygic comprises of a progression of injections into the melanoma lesions. After the initial infusion, a second measurement is managed three weeks later, trailed by extra dosages every two weeks for no less than six months, unless other treatment is required or until there are no remaining injectable lesions to treat.
As per Melanoma Research Foundation (MRF), Imlygic speaks another way to deal with treating melanoma, a cancer that is expanding in incidence at an alarming rate. Dissimilar to already endorsed drugs that are given intravenously or by pill, this treatment is injected specifically into the tumor and is the first intralesional treatment affirmed by the FDA for the treatment of cancer.

Since Imlygic is a modified live oncolytic herpes virus therapy or treatment, herpes infection disease can likewise happen.
