A Study of TBio-4101 (TIL) and Pembrolizumab in Patients With Advanced Solid Tumors

Key Inclusion Criteria: * Advanced or metastatic breast carcinoma, colorectal adenocarcinoma, uveal melanoma, cutaneous melanoma, non-small cell lung cancer, or head and neck squamous cell carcinoma that has failed or is refractory to standard of care therapy * Have at least one target lesion that can be used for response assessments and have at least 1 tumor amenable for tissue harvest for TIL manufacturing. * ECOG performance status of 0 or 1 * Demonstrate adequate organ function * Additional inclusion criteria exist Key Exclusion Criteria: * Known additional malignancy that is progressing or has required active treatment within the past 3 years * Diagnosis of immunodeficiency or receiving chronic systemic steroid therapy or any other form of immunosuppressive * Currently infected with HIV Type 1 and Type 2, hepatitis B virus (HBV), hepatitis C virus (HCV), treponema pallidum (e.g., syphilis), West Nile virus (WNV), Human T-lymphotropic virus types 1 or II (HTLV I/II), or cytomegalovirus (CMV) * Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable * Serious cardiac condition, such as uncontrolled hypertension, concurrent congestive heart failure, prior history of Class III/IV cardiac disease (New York Heart Association \[NYHA\]), history of cardiac ischemia within the past 6 months, or prior history of cardiac arrhythmia requiring treatment. Patients who are \> 60 years of age must undergo cardiology clearance exam and cardiac stress test. * Prior cell therapy or organ transplant * History of severe immediate hypersensitivity reaction to cyclophosphamide, fludarabine, IL-2, or pembrolizumab, or any of their constituents * LVEF ≤ 45% * FEV1 ≤ 60% of predicted value and DLCO (corrected) \< 60% of predicted value * Chronic anti-coagulant therapy that cannot either be discontinued or temporarily changed * Additional exclusion criteria exist
