Brief Summary:
Single-centre, first-in-man phase I/II trial to demonstrate safety and efficacy of MAGE-C2/HLA-A2 TCR T cells (MC2 TCR T cells) in advanced melanoma (MEL) and head-and-neck carcinoma (HNSCC).

Condition or disease Intervention/treatment Phase
Melanoma Melanoma, Uveal Head and Neck Cancer Biological: Adoptive therapy with autologous MC2 TCR T cells Phase 1 Phase 2

Detailed Description:

In this patient study, the investigators target the Cancer Germline Antigen (CGA) MAGE-C2 (MC2), and use T cells with a young phenotype. MC2 is highly expressed in melanoma (MEL) and head-and-neck squamous cell carcinoma (HNSSC), but not in healthy adult tissues. The investigators isolated MC2-specific TCRs from MEL patients who showed clinical responses following vaccination that were accompanied by significant frequencies of anti-MC2 CD8 T cells in blood and tumor without apparent side effects. Following extensive evaluation of in vitro anti-tumor and self-reactivities, the investigators have selected a TCR that recognizes the ALK epitope in the context of HLA-A2 for clinical development. Furthermore, preclinical studies showed that epigenetic pretreatment of tumor cells, but not normal cells, up-regulated MC2 gene expression and resulted in enhanced recognition of MC2 by the selected TCR. In parallel to the above studies, the investigators renewed their GMP protocol to process T cells, using stimulating antibodies and cytokines, to generate T cells with a young phenotype.

In the current phase I/II study, the investigators explore the safety and anti-tumor efficacy of T cells engineered with the selected TCR in patients with MC2-positive MEL and HNSSC. The study contains the following unique elements:

  • CGA not targeted before by T cell therapy
  • New T cell processing method to generate young T cells
  • Pretreatment of patients with epigenetic drugs
  • No chemotherapy prior to T cell infusion

  • Clinical PI: Astrid van der Veldt, MD, PhD
  • Clinical logistics: Karlijn de Joode, MD
  • T cell production: Monique de Beijer, PhD; and Cor Lamers, PhD
  • Coordinator/Preclinical PI: prof. Reno Debets, PhD

Arm Intervention/treatment
Experimental: Adoptive therapy with autologous MC2 TCR T cells
  • Accelerated titration phase I design and a subsequent single arm phase II study
  • Prior to T cell transfer (day 0), patients will be treated with valproic acid (dose 50 mg/kg/d, 7d; days -9 to day -3) and 5' azacytidine (dose 75mg/m2/d, 7d; days -9 to day -3)
  • Phase I: patients will be treated with one single intravenous administration of MC2 TCR T cells at 5 different escalated doses of 5x10E7, 5x10E8, 5x10E9,1.0x10E10, and the total number of cultured TCR T cells (i.e., usually 1.0-5.0 x10E10 TCR T cells). MC2 TCR T cell infusions will be supported by low dose of IL-2 administrations (s.c. 5x10E5 IU/m2 2qd for 5 days)
  • T cells will be processed using IL-15 and IL-21 to generate young T cells
Biological: Adoptive therapy with autologous MC2 TCR T cells
Adoptive therapy with autologous MC2 TCR T cells combined with AZA/VP
Other Names:
  • 5' Azacytidine (AZA)
  • Valproic acid (VP)
  • Interleukin 2 (IL2)




Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) of MC2 TCR T cells [ Time Frame: 1 year ]
    MTD is determined using an accelerated titration phase with T cell doses as described in treatment arm; AEs are recorded according to CTCAE 5.0

  2. Objective anti-tumor responses of MC2 TCR T cells [ Time Frame: 2 years ]
    Anti-tumor responses are recorded according to RECIST v1.1 using the MTD from outcome 1

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Written informed consent;
  2. Age ≥ 18 years;
  3. One of the following three malignancies:

    • Previously treated for unresectable or metastatic cutaneous or mucosal melanoma for whom no standard treatment is available (anymore);
    • Metastatic uveal melanoma, progressing after standard of care therapy, if available;
    • R/M HSNCC for whom no standard treatment is available anymore;
  4. Patients must be HLA-A2*0201 positive;
  5. Primary tumor and/or metastasis (archival or fresh biopsy) is positive for MC2 (>5% of tumor cells) according to immunohistochemistry;
  6. Measurable disease according to RECIST v1.1;
  7. At least one lesion, suitable for sequential mandatory tumor biopsies;
  8. ECOG performance status of 0 or 1. Life expectancy ≥ 12 weeks;
  9. Patients with melanoma must have had objective evidence of disease progression while on or after standard systemic therapy. The last dose of prior therapy (e.g. anti- PD-1, chemotherapy) must have been received more than 4 weeks prior to the start of study treatment. For melanoma patients who are treated with BRAF- and MEK inhibitors, an interval of 2 weeks between discontinuation of BRAF- and MEK inhibition and start of study treatment is sufficient;
  10. Patients with R/M HNSCC must have had objective evidence of disease progression and are ineligible for or unwilling to get platinum-based chemotherapy or for whom no standard treatment is available;
