A Study to Investigate the Efficacy and Safety of an Infusion of IOV-4001 in Adult Participants With Unresectable or Metastatic Melanoma or Stage III or IV Non-small-cell Lung Cancer

This study is the first-in-human study of IOV-4001, a genetically modified autologous tumor- infiltrating lymphocytes (TIL) product. IOV-4001 is expected to have antitumor activity through its capacity to directly target and kill tumor cells in a manner that is similar to non-genome-edited TIL, but with the potential for enhanced antitumor activity due to disruption of PDCD1, the gene for programmed cell death protein-1 (PD-1).
