Pilot Study of Affinity-enhanced Anti-NY-ESO-1 TCR Engineered Autologous T Cells in NSCLC Patients (NCT03029273)

Guangdong Xiangxue Precision Medical Technology Co., Ltd
TCR-T cell therapy experienced a breakthrough for treating tumors in recent years. Phase I / II trial of NY-ESO-1-specific TCR-T treatment for synovial sarcoma and melanoma conducted by the Rosenberg team at the National Cancer Institute showed that 61% Synovial cell sarcoma and 55% melanoma had therapeutic responses. Another report of a phase I / II clinical trial for multiple myeloma showed that 20 patients received high affinity anti-NY-ESO-1 and LAGE-1 specific TCR-T treatment, 16 of them (80%) had the average progression-free survival of 19.1 months with minor side effect. These achievements indicate that TCR-T cell therapy can target a variety of tumors including solid tumors without any severe side effects found in CAR-T trials. This study is mainly focused on tumor testis antigen (Cancer-Testis Antigen), because it is not expressed in normal cells. NY-ESO-1 antigen is commonly expressed in 10-50% of melanoma, lung, liver, esophageal, breast, prostate, bladder, thyroid and ovarian cancer cases, 60% of multiple myeloma cases, and 70-80% of synovial cell sarcoma. Approximately 700,000 new cases of lung cancer are identified each year in China, 70% of them die within one to two years after diagnosis due to the lack of effective treatment. To address that unmet needs, our TCR-T treatment targets non-small cell lung cancer with NY-ESO-1 antigen expression. This study will investigate the safety and tolerability of TAEST16001 (TAEST: TCR Affinity Enhancing Specific T cell Therapy, autologous T cells transduced with affinity enhanced NY-ESO-1 TCR) cell therapy in subjects with NSCLC who have received prior therapy for their disease but their disease has progressed or relapsed.
  • Drug: Cyclophosphamide
    Three days prior to infusion of TCR-T cell, subjects receive cyclophosphamide treatment at dose 1 g/day for 2 days and take a rest for one day before infusion.
    • Biological: Anti-NY-ESO-1 TCR transduced T cells
      A single dose of Anti-NY-ESO-1 TCR transduced T cells (about 5×109) will be intravenously (i.v.) administered Additionally, following infusion of Anti-NY-ESO-1 TCR transduced T cells, IL-2 subcutaneous injections (250,000 IU/day) will be administered for 14 days concomitantly to each subject.

      This Phase 1 study is designed as a cell dose escalation trial evaluating the safety of TAEST16001 T cell therapy in subjects with NSCLC who have received prior therapy for their disease but the disease has progressed or relapsed. Anti-tumor activity and other exploratory objectives will be assessed. Subjects enter from a Screening Protocol and are positive for HLA-A2*02:01 and have tumor that express NY-ESO-1. The subjects will be evaluated DLT and MTD using a modified 3+3 cell dose escalation design to determine the cell dose range. Subjects will receive cytoreductive chemotherapy with cyclophosphamide 1g/day on days -3 and -2 followed by infusion of dose of about 5×109 TAEST16001.

      Subjects will stay in hospital for safety and efficacy assessment daily from T cell infusion (Day 0) through Day 7, and then weekly until week 4 and then at 8 weeks, 12 weeks, 16 weeks and every 3 months until progression of their disease.
