Marrow Infiltrating Lymphocytes - Non-Small Cell Lung Cancer (MILs™ - NSCLC) Alone or in Combination With Nivolumab With or Without Tadalafil in Locally Advanced and Unresectable or Metastatic NSCLC

This study will examine the safety and efficacy of Marrow Infiltrating Lymphocytes-Non-Small Cell Lung Cancer (MILs™ - NSCLC) combined with nivolumab with or without tadalafil in subjects with locally advanced and unresectable and metastatic NSCLC who were refractory to, or have relapsed on, an anti-PD-1 containing regimen. MILs™ - NSCLC are an adoptive cell therapy product derived via the activation and expansion of bone marrow T cells. Subjects will have bone marrow harvested during the Screening Period which will be used to manufacture the MILs™ - NSCLC. The MILs™ - NSCLC will then be administered on Day 0. Nivolumab will be administered on Day 1 and will continue every four weeks until treatment discontinuation. Tadalafil will be administered on Day 1 and will continue daily until treatment discontinuation.
