til therapy for patients with advanced solid tumors

Conditions: Advanced Breast Cancer; Advanced Lung Cancer

Summary: this study is a phase i clinical trial to investigate the safety and tolerability of neog-100 in patients with advanced breast cancer and lung cancer. neog-100, an autologous tumor infiltrating lymphocytes (tils), is infused intravenously into the patient after non-myeloablative (nma) lymphodepletion treatment.

study treatment will begin with intravenous nma lymphodepleiting regimen composed by cyclophosphamide and fludarabine, followed by infusion of neog-100. cyclophosphamide will administered for two days and fludarabine for five days. patients in cohort 1 will receive neog-100 and patients in cohort 2 will receive neog-100 plus low-dose (2 miu) il-2.
