What is the primary function of the leukapheresis procedure?
Answer
To collect T-cells from the patient
Leukapheresis is the essential first step in the CAR T-cell therapy protocol. This procedure involves drawing blood from the patient, passing it through equipment to isolate specific white blood cells including the T-cells, and returning the remaining blood components to the patient. This collected sample serves as the raw material that will be sent to a manufacturing facility to be engineered and expanded into a therapeutic dose.
