- Cohort 2 will be initiated with amendment D whereby CD4+ cells will be eliminated from the cultures, using the Miltenyi Clinimacs apparatus, prior to performing the rapid expansion of the young TIL cells. Patients in cohort 2 will receive CD4+ cell depleted young unselected TIL. Patients will also receive high dose IL-2 after non-myeloablative but lymphodepleting chemotherapy preparative regimen as described above for cohort 1. Clinical and immunologic response will be evaluated about 4-6 weeks after TIL infusion. Using a small optimal two-stage Phase II design, initially 18 patients will be enrolled, and if three or more of the first 18 patients have a clinical response (PR or CR), accrual will continue to 35 patients, targeting a 30% goal for objective response. With the initiation of Cohort 3 with amendment H, patients will only be accrued to Cohort 2 if they are not eligible to receive 600 cGy due to prior radiation, or to inability to mobilize cluster of differentiation 34 (CD34+) cells. Also at this time, accrual will be expanded to a total of 50 patients in cohort 2. Cohort 2 will be closed with amendment K.
