SCIB1 is a genetically-engineered cancer vaccine being developed by Scancell Holdings Plc as a treatment for melanoma. [1] SCIB1 is a plasmid DNA which encodes a human antibody molecule engineered to express two cytotoxic T cell epitopes derived from the melanoma antigens Tyrosinase-Related Protein 2 (TRP2) and gp100 plus two helper T cell epitopes.
DNA vaccine and Gene therapy techniques are similar. DNA vaccines have been introduced into animal tissues by multiple methods. In 1999, the two most popular approaches were injection of DNA in saline: by using a standard hypodermic needle, or by using a gene gun delivery. [31] Several other techniques have been documented in the intervening years.
A nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues.
A genetic vaccine (also gene-based vaccine) is a vaccine that contains nucleic acids such as DNA or RNA that lead to protein biosynthesis of antigens within a cell. Genetic vaccines thus include DNA vaccines , RNA vaccines and viral vector vaccines .
SV40 large T antigen (Simian Vacuolating Virus 40 TAg) is a hexamer protein that is a dominant-acting oncoprotein derived from the polyomavirus SV40. TAg is capable of inducing malignant transformation of a variety of cell types.

The duo have partnered since 2016 with a focus on cancer, where Merck is a dominant player for therapies, but the Phase 2 results are the first promising for a any cancer vaccine.
Last year the UK government signed an agreement with Germany-based BioNTech to launch clinical trials providing "personalised cancer treatments", aiming to reach 10,000 patients by 2030.
