A Phase 2 Study to Evaluate the Efficacy and Safety of Adoptive Transfer of Autologous Tumor Infiltrating Lymphocytes in Patients with Locally Advanced, Recurrent, or Metastatic Biliary Tract Cancers

This Phase 2 study will be conducted in conjunction with the companion harvest protocol protocol in patients with measurable disease who have lesions that can be resected or biopsied for Tumor Infiltrating Lymphocyte(TIL) growth. The Treatment Phase begins once the cells exceed the cell growth and potency requirements in the companion protocol.
