Chimeric Antigen Receptor T-Cell Immunotherapy
CAR-T cell immune-therapies may completely change the reality of cancer treatment
The core mechanism of CAR-T therapy is enabling the effector T cell to identify specific tumor antigens by adding tumor antigen receptor to T cell, resulting in prolonged and drastic increase of targeted killing of tumor cells and to overcome host immune tolerance and immune escape.
Clinical Advantages
- Relatively more safe
It is widely proved to be a safe and effective
biotherapy
- Better targeting and higher specificity
Pinpoint elimination of tumor cell to avoid
damaging normal cells
- Improved clinical results
90% effective rate, over 60% cure rate
- Less adverse reactions
The least side effects of current anti-cancer
therapies clinically available
Risks of Old Generation CAR-T
- OFF-TARGET EFFECT May causes severe autoimmune reaction of normal tissue.
CYTOKINE STORM
large amount of TNF-α, IL-1, 6, 8, 12, IFN-α, β, γ, MCP-1 etc. released into
the system can cause respiratory distress syndrome, multiple organ failure
and cerebral edema.
INSERTION MUTATION
Insertion of foreign DNA fragment disrupted original gene structure causing
“insertion mutation”. The long term stay or circulation of mutated T cell
theoretically caries tumorigenesis risks.
