What is the News?
Immunoadoptive Cell Therapy Private Limited (Immune ACT) has received Central Drugs Standard Control Organisation(CDSCO) approval for the ‘first’ humanized Chimeric Antigen Receptor T cell (CAR-T cell) therapy named NexCAR19.
Note: ImmunoACT is an IIT Bombay incubated company.
What is NexCAR19?
NexCAR19 is an indigenously developed CAR-T cell therapy.
Developed by: IIT Bombay and Tata Memorial Centre.
The therapy has been approved for the treatment of relapsed / refractory B-cell lymphomas and leukemia.
What is CAR-T cell therapy?

CAR T-cell therapy, or chimeric antigen receptor T-cell therapy is a major breakthrough in cancer treatment.
Unlike chemotherapy which involves taking drugs, CAR T-cell therapies use a patient’s own cells.They are modified in the laboratory to activate T-cells and target tumor cells.
Currently, this therapy is offered as a second-line treatment for late-stage leukaemia and lymphoma when patients do not respond to conventional treatments like chemotherapy and bone marrow transplants or experience relapsed cancer.
How does CART-T cell therapy work?
First, a patient’s T cells are extracted from their blood.The extracted T cells are then genetically modified in a laboratory.
Scientists then introduce a synthetic gene into the T cells, which encodes a chimeric antigen receptor (CAR).This receptor is designed to target a specific protein or antigen found on the surface of cancer cells.
After genetic modification, the T cells are cultured and allowed to multiply to create a larger population of these modified cells.
Once a sufficient number of CAR T cells have been generated, they are infused back into the patient’s bloodstream.The CAR T cells then circulate throughout the body, seeking out and binding to the cancer cells with the targeted antigen.
When the CAR T cells encounter cancer cells with the specific antigen, they become activated and attack the cancer cells.This immune response can lead to the destruction of the cancer cells.
