Immunocore today announced that the FDA has awarded its innovative T-cell-infusion (TCR) therapy tebentafusp (IMCgp100) breakthrough therapy for the treatment of non-removable or metastasis vine melanoma (mUM) adult patients who are HLA-A-02:01 positive.
, tebentafusp would be the first new treatment for metastasis staphylocosal melanoma in 40 years, according to a press release.
Tebentafusp innovatively combined TCR targeting tumor antigens with immune-effect domains that bind to CD3 subjects.
designed to guide and activate T-cells, allowing them to identify and kill cancer cells.
Tebentafusp specific target gp100, an antigen expressed in melanin cells and melanoma.
is concerned that the company's technology allows TCR to identify cancer antigens in cells with high affinity, which is expected to break through the limitations of existing antibody drugs and increase the number of identifiable targets from 10 percent to 90 percent.
In addition, based on existing mechanisms for T-cell immersion of human tumors, Immunocore also points out that its TCR technology is expected to be used to treat immunologically "cold tumors", tumors with low mutation rates that have traditionally been difficult to attract the attention of the immune system.
breakthrough therapy is based on the results of Phase 3 clinical trials published in November 2020.
-term analysis showed that tebentafusp showed significant survival benefits in treating patients with primary metastasis melanoma compared to other therapies chosen by the researchers, including dacarbazine, ipilimumab, or pembrolizumab.
although the data are not yet fully mature, the tebentafusp group currently has a one-year survival rate of 73%, better than the other treatment groups of 58%.
