• locally manufactured adoptive cellular therapeutic (ACT) product · EXPERIMENTAL · Single dose, intrapleural delivery (via indwelling pleural catheter) of adoptive cellular therapy (ACT) product derived from autologous pleural infiltrating T-cells. Low dose Interleukin-2 (IL-2) will also be administered intrapleural at the dose of 20 milliliters (mL) at 1 x 10⁵ International Units (IU)/mL starting approximately 2 hours after ACT infusion and every 8 to 16 hours thereafter, as tolerated, for up to 4 doses (total 8 x 10⁶ IU).

This research study aims to evaluate the safety and effectiveness of a novel immunotherapy, Fast TIL, an Adoptive Cellular Therapeutic (ACT), to fight cancer that has spread to the pleura or pleural mesothelioma. The ACT product is created at AHN West Penn using the participant's pleural infiltrating T-cells (PIT). It is administered through a pleural catheter along with the drug Interleukin-2 (IL-2). Based on previous research it is believed that it may help fight the tumor and relieve symptoms. As a participant, their pleural fluid will be collected and the PIT cells will be isolated and expanded in the lab to create the ACT product. Before receiving the ACT product through their pleural catheter, they will undergo outpatient lymphodepleting chemotherapy. LDC is a standard procedure for many approved immunotherapy treatments Following the infusion, they'll receive IL-2 through the catheter for two days to stimulate the expanded PIT cells. The active treatment phase lasts about three weeks, with follow-up visits over five years at AHN West Penn Hospital, potentially requiring a hospital stay of up to six days. Blood samples will be taken to monitor their response. As this is a first-in-human study, treatment carries an unknown risk up to and including death from toxicity. However, the risks of similar immunotherapy treatments are well documented.
