Brief Summary:
The aim of this study is to determine the safety, tolerability and anti-tumoral activity of autologous T cells transduced with a T cell receptor specific for MAGE-A1 in eligible patients with advanced solid tumors.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Biological: Autologous CD8+ T-cells, transduced with MAGE-A1 directed TCR Phase 1 Phase 2

Detailed Description:
This is a Phase 1/2, first-in-human, open-label, two-part clinical trial of TK-8001 (MAGE-A1-directed TCR-transduced autologous CD8+ T-cells) in patients with HLA-A*02:01 genotype and advanced-stage/metastatic, MAGE-A1+ solid tumors that either have no further approved therapeutic alternative(s) or are in a non-curable state as per the Investigator's assessment and have received a minimum of two lines of systemic therapy. The trial will consist of a Phase 1 Part and a Phase 2 Part. In the Phase 1 Part (dose-escalation), at least 6 patients and up to 18 patients (if DLT occurs) will receive escalating doses of TK-8001. In the Phase 2 Part (expansion), up to 30 patients will receive TK-8001 to further evaluate the efficacy and safety of TK-8001 and to confirm the RP2D. Both the Phase 1 Part (dose-escalation) and Phase 2 Part (expansion) of the trial will consist of the following periods: Screening and Leukapheresis Period, Screening II, Conditioning Period, TK-8001 Treatment Period, DLT Monitoring Period, Core Follow-up Period (Year 1), Long-term Follow-up Period (Year 2 - 15).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 48 participants
Allocation: N/A
Intervention Model: Sequential Assignment
Intervention Model Description: The trial will consist of a Phase 1 Part and a Phase 2 Part. After Phase 1 Part (dose-escalation) a Phase 2 Part (expansion) will follow. In total, up to 48 patients may receive TK-8001 to further evaluate the efficacy and safety of TK-8001 and to confirm the recommended phase 2 dose (RP2D).
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/2, First-in-Human, Open-Label, Two Part Clinical Trial of TK-8001 (MAGE-A1--Directed TCR Transduced Autologous CD8+ T-cells) in Patients With HLA-A*02:01 Genotype and Advanced Stage/Metastatic, MAGE-A1+ Solid Tumors That Either Have No Further Approved Therapeutic Alternative(s) or Are in a Non-Curable State and Have Received a Minimum of Two Lines of Systemic Therapy
Actual Study Start Date : July 29, 2022
Estimated Primary Completion Date : June 2024
Estimated Study Completion Date : June 2037

Arm Intervention/treatment
Experimental: MAGE-A1 - directed TCR transduced autologous T-cells
Single-dose, intravenous infusion
Biological: Autologous CD8+ T-cells, transduced with MAGE-A1 directed TCR
Single-dose intravenous infusion of MAGE-A1 directed TCR-transgenic T cells following a conditioning chemotherapy

Primary Outcome Measures :
  1. Number of participants with treatment-emergent Adverse Events as assessed by CTCAE v5.0 (Part 1 of trial) [ Time Frame: Up to 15 years after TK-8001 treatment (52 weeks core follow-up, 14 years long-term follow up) ]
    Incidence and grade of treatment emergent adverse events and serious adverse events number and type of dose-limiting toxicities

  2. Antitumoral activity of TK-8001 (Part 2 of trial) [ Time Frame: Up to 15 years after TK-8001 treatment, or until disease progression ]
    Evaluation of overall response rate, rate of stable disease, partial response, and complete response rates of TK-8001 monotherapy, according to RECIST Version 1.1 and iRECIST

Secondary Outcome Measures :
  1. End of dose escalation [ Time Frame: 28 days after TK-8001 treatment of last patient in part 1 ]
    RP2D will be determined through integrated evaluation of adverse events, serious adverse events, antitumoral activity, and evaluation of the biological and physiological effects of TK-8001 in the body.
