These results come from the Phase I and II trials of therapy, where researchers assess its safety and effectiveness against a given condition.

Key findings of Report 

  • Lower costs: Cost is 1/20th of similar global therapies.
  • Side Effects & Risks: Most common side effects reported by study were anemia in 61% participants, low platelet count in 65% patients, low count of white blood cells etc.

About CAR (Chimeric Antigen Receptor) T-Cell Therapy

The image titled "CAR T-cell Therapy" illustrates the process of using genetically modified T cells to treat cancer. The key steps in the process are:  Remove blood from the patient to obtain T cells – T cells are extracted from the patient's bloodstream. Make CAR T cells in the lab – A gene for a Chimeric Antigen Receptor (CAR) is inserted into T cells to help them recognize cancer cells. Grow millions of CAR T cells – The modified CAR T cells are expanded in a lab. Infuse CAR T cells into the patient – The modified cells are reintroduced into the patient's body. CAR T cells bind to cancer cells and destroy them – The engineered CAR T cells recognize cancer cell antigens, bind to them, and kill them. The infographic visually explains this immunotherapy method, which has shown promising clinical trial results in India. Let me know if you need further insights!
  • It modifies immune cells, specifically T-cells, by turning them into potent cancer fighters known as CAR-T cells.
    • T-cells are special cells (types of white blood cells) whose primary function is cytotoxic, meaning killing other cells.
  • This treatment is designed for specific types of blood cancer and is given to patients whose cancer has either relapsed or not responded to first-line treatment.

Benefits of CAR T-Cell therapy

  • Short treatment duration: Unlike aggressive chemotherapy or stem cell transplants, it allows for a faster recovery.
  •  A "Living Drug" with Sustained Benefits: CAR T-cells persist in the body, offering long-term protection against cancer relapse.

Challenges

  • Cytokine Release Syndrome: Over activation of immune cells leads to high fever, organ failure etc.
  • Neurotoxicity: Ranges from confusion and seizures to cerebral edema and coma.
  • Antigen Escape: Tumors develop resistance by losing antigen targeted by CAR-T cells.
