ATLCAR.CD30 cells will be administered as described below 1-4 days (preferably 1-2 days) after lymphodepletion with bendamustine and fludarabine. ATLCAR.CD30 cells will be given by a licensed provider (oncology nurse or physician) via intravenous injection over 1-10 minutes through either a peripheral or a central line. The expected volume will be 1-50cc. Patients with a partial response or stable disease at 6 weeks may receive a second infusion of ATLCAR.CD30 if cells are available. Note: Lymphodepletion with bendamustine and fludarabine will occur for three consecutive days and will not be given prior to a second infusion of cells (if applicable).
