A multicenter trial to investigate TBio-4101, an autologous, neoantigen-selected, tumor-reactive TIL product, in patients with advanced solid malignancies.

Official Title

A Phase 1b Study of TBio-4101 (Autologous Selected and Expanded Tumor-Infiltrating Lymphocytes [TIL]) and Pembrolizumab in Patients With Advanced Solid Tumor Malignancies (STARLING)


This is a Phase 1 study to investigate TBio-4101. TBio-4101 is an autologous tumor infiltrating lymphocyte (TIL) therapy that utilizes tumor specific antigens to select, sort, and expand patient-specific tumor-reactive T-cells to be reinfused into the patient. The adoptive cell therapy is further enhanced through the use of non-myeloablative chemotherapy prior to TIL infusion, followed by the TIL plus IL-2 infusion. Low-dose radiation therapy is administered prior to and after TIL plus IL-2 infusion. Pembrolizumab is provided after the resolution of IL-2 toxicities. The trial is open to solid tumors of varying tumor mutational burdens.

You can join if…

Open to people ages 18-70

  • 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

You CAN'T join if...

  • 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)
