A Phase 1b/2a Pilot Study to Evaluate the Safety and Tolerability of Autologous T-Cells Expressing Enhanced TCRs (T Cell Receptors) Specific for NY-ESO-1/LAGE-1a (GSK3377794) Alone, or in Combination With Pembrolizumab in HLA-A2+ Participants With NY-ESO-1- or LAGE-1a-Positive Advanced or Recurrent Non-Small Cell Lung Cancer
Adoptive T-cell therapy (ACT) is a therapeutic approach that uses T lymphocytes of participants with cancer, obtained by leukapheresis with the aim of generating an anti-tumour T-cell immune response. New York esophageal squamous cell carcinoma 1 (NY-ESO-1) and cancer testis antigen 2 (LAGE-1a) antigens are tumour-associated proteins that have been found in several tumour types. Clinical trials using ACT with T-cells directed against NY-ESO-1/LAGE-1a have shown objective responses in participants with cancer. Pembrolizumab is a monoclonal antibody that acts specifically on tumour targeting T-cells and increases T-cell anti-tumour function. Pembrolizumab will be used in combination with NY-ESO-1/LAGE-1a T Cell Receptors (TCR) engineered participant T-cells (GSK3377794) to potentially further improve therapy for participants. The primary objective of the study is to evaluate the safety and tolerability of autologous genetically modified T-cells (GSK3377794) in human leukocyte antigen (HLA) positive participants with NY-ES0-1/ LAGE-1a positive advanced non-small cell lung cancer (NSCLC) alone (Arm A) or GSK3377794 in combination with pembrolizumab in participants with NSCLC with wildtype epidermal growth factor receptor (WT EGFR) and WT anaplastic lymphoma kinase/ c-ros oncogene 1 (ALK/ROS1) (Arm B) and participants with NSCLC with EGFR or ALK/ROS1 aberration (Arm C). This study consists of screening phase, Leukapheresis/ GSK3377794 manufacture, lymphodepletion/treatment phase and follow-up. Participants will receive GSK3377794 as monotherapy (Arm A); or as a combination therapy with pembrolizumab (Arm B), and participants in Arm C will receive the same treatment as participants in the Arm B. Approximately 54 participants will be enrolled into the study.
