_____
For Approved NMIBC Treatment (No Apheresis): Anktiva is FDA-approved for BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) in combination with BCG.
In this setting, it is administered via a catheter directly into the bladder (intravesical), and does not require apheresis or chemotherapy.
For Experimental CAR-NK/Memory Cell Therapy (Requires Apheresis):
When used in combination with Memory Cytokine-Enriched Natural Killer (M-ceNK) cells—such as in trials for glioblastoma or pancreatic cancer—the treatment involves apheresis to collect the patient’s own immune cells for activation and expansion outside the body, followed by re-infusion.
