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).

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

Study Groups

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

Eligibility 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;

11. Patients of both genders must be willing to practice a highly effective method of birth control during treatment and for four months after receiving the preparative regimen;

12. Patients must meet the following laboratory values at the screening visit in the absence of growth factors and/or transfusion support:

Hematology:

• absolute neutrophil count greater than 1.5x10^9/L;
• platelet count greater than 75x10^9/L;
• hemoglobin greater than 5 mmol/L or 8.0 in g/dl;

Chemistry:

• serum ALAT/ASAT less than 3 times the upper limit of normal (ULN), unless patients have liver metastasis (<5 times ULN);
• serum creatinine < 1.5 ULN;
• total bilirubin ≤ 20 micromol/L, except in patients with Gilbert's Syndrome who must have a total bilirubin ≤ 50 micromol/L;

Serology:

• seronegative for HIV antibody;
• seronegative for hepatitis B antigen, and hepatitis C antibody;
• seronegative for lues.

Exclusion Criteria

Subjects who meet any of the following criteria will be excluded from participation of this study:

1. presence of symptomatic brain metastasis. Note: subjects with symptomatic brain lesions who have been definitively treated with stereotactic radiation therapy, surgery, or gamma knife therapy are eligible;

2. Presence of active brain metastasis defined as new or progressive brain metastasis at the time of study entry. Note: subjects with treated or stable brain metastasis are eligible;

3. Presence of leptomeningeal metastasis;

4. Presence of malignant pleural effusion or ascites;

5. Systemic chronic steroid therapy (>10 mg/day prednisone or equivalent) or any other immunosuppressive therapy within 7 days prior to leukapheresis or 72 hours prior to infusion of the MC2 TCR T cells. Note: local steroids such as topical, inhaled, nasal and ophthalmic steroids are allowed;

6. Active, known or suspected autoimmune disease or a documented history of autoimmune disease. Note: subjects with vitiligo, controlled type 1 diabetes mellitus on stable insulin dose, residual autoimmune-related hypothyroidism only requiring hormone replacement or psoriasis not requiring systemic treatment are permitted;

7. Any active systemic infections, coagulation disorders or other active major medical illnesses, such as active autoimmune diseases requiring anti-TNF treatment;

8. History of myocardial infarction, cardial angioplasty or stenting, unstable angina, or other clinically significant cardiac disease within 6 months of enrollment;

9. AEs of previous treatment. Toxicities associated with prior systemic and non- systemic treatment must have recovered to a grade 1 or less. Patients may have undergone minor surgical procedures or palliative radiotherapy (for non-target lesions) within the past 4 weeks, as long as all toxicities have recovered to grade 1 or less;

10. Women who are pregnant or breastfeeding. A negative pregnancy test before inclusion in the trial is required for all women of child bearing age;

11. Use of any live vaccines against infectious diseases within the last 3 months;

12. Active infection requiring systemic antibiotic therapy at start of study treatment;

13. Prior allogenic bone marrow or solid organ transplant;
