MAGE-A10ᶜ⁷⁹⁶T for Urothelial Cancer, Melanoma or Head and Neck Cancers
Phase 1 Cell Dose Escalation Study to Assess the Safety and Tolerability of Genetically Engineered MAGE-A10ᶜ⁷⁹⁶T in HLA-A2+ Subjects With MAGE-A10 Positive Urothelial, Melanoma or Head and Neck Tumors
This study will investigate the safety and tolerability of MAGE A10ᶜ⁷⁹⁶T cell therapy in subjects who have the appropriate HLA-A2 tissue marker and whose melanoma or bladder or head and neck tumor has the MAGE-A10 protein expressed. This study will take a subject's T cells and give them a T cell receptor protein that recognizes and attacks the tumors.

This Phase 1 study is designed as a cell dose escalation trial in HLA-A2*02:01 and -A*02:06 subjects with MAGE-A10 positive urothelial, melanoma or head and neck tumors. 16-22 subjects with inoperable or metastatic (advanced) urothelial cancer, head and neck cancer, or melanoma will be treated in this study. The study will enroll subjects using a modified 3+3 cell dose escalation design to evaluate dose limiting toxicities and determine the target cell dose range. Following the dose escalation phase additional subjects will be enrolled until 10 subjects are treated at the target cell dose range to further characterize safety, tolerability and anti-tumor activity.

Subjects may be screened in the Screening Protocol (ADP-0000-001) for the presence of HLA-A2*02:01 and/or HLA-A*02:06 and have MAGE-A10 expression in the tumor. The absence of HLA-A*02:05 in either allele, HLA-B*15:01 or HLA-B*46:01 will also be assessed. The presence of HLA A*02 null allele (designated with an "N", e.g. A*02:32N) as the sole HLA-A*02 allele will also be assessed as these are study exclusion criteria.

Leukapheresis is performed to obtain cells for the manufacture of autologous MAGE-A10ᶜ⁷⁹⁶T cell receptor (TCR) bearing T cells. Leukapheresis should be performed as soon as possible after the subject is determined to be eligible for study participation.

When the manufactured MAGE-A10ᶜ⁷⁹⁶T cells are available, subjects will undergo lymphodepleting chemotherapy with cyclophosphamide and fludarabine followed by infusion of MAGE-A10ᶜ⁷⁹⁶T on Day 1.

Safety and tolerability as well as anti-tumor activity and biomarker assessments to be conducted at each visit are outlined in the Schedule of Procedures. Anti-tumor activity will be assessed using RECIST v1.1 criteria.

All subjects, completing or withdrawing from the interventional portion of the study, will be rolled over to a long term follow-up (LTFU) protocol for observation of delayed adverse events for 15 years post-infusion in accordance with FDA and EMA requirements for gene therapy clinical trials as well as for overall survival. FDA and EMA follow-up requirements for gene therapy clinical trials, continues after the subject has been confirmed to have progression of disease.

  5. Subject has measurable disease according to RECIST 1.1 criteria prior to lymphodepletion. Measurable disease is not required prior to leukapheresis.
  6. Subject has the following disease specific requirements for their tumor type:

    • Inoperable or metastatic (advanced) urothelial cancer

      • Has received a platinum containing regimen in the adjuvant or metastatic setting or is ineligible for, or has refused platinum as part of the prior chemotherapy regimen; may have received prior immunotherapy.
    • Inoperable or metastatic (advanced) melanoma

      • Has received a PD-1 inhibitor and/or a CTLA-4 inhibitor.
      • Has received BRAF inhibitor or the combination of BRAF and MEK inhibitors for BRAFv600 mutant melanoma.

      • May have received a platinum containing chemotherapy for treatment of primary tumor in adjuvant or metastatic setting or refused such treatment. May have received prior immunotherapy.
  7. Subject is HLA-A*02:01 and/or HLA-A*02:06 positive. (This determination will be made under screening protocol ADP-0000-001).
  8. Subject's tumor (either an archival specimen or a fresh biopsy) shows positive MAGE-A10 expression. The threshold requirement for MAGE-A10 expression by IHC is defined in the Study Procedures Manual. All samples must have been pathologically reviewed by an Adaptimmune designated central laboratory confirming expression. (This determination will be made under screening protocol ADP-0000-001).
  9. Subject has anticipated life expectancy >3 months

  7. Subject has symptomatic CNS metastases. Subject with a prior history of symptomatic CNS metastases must have received treatment (i.e., stereotactic radiosurgery (SRS), whole brain radiation (WBRT) or surgery) and be neurologically stable for at least 1 month, not requiring anti-seizure medications and off of steroids for at least 14 days prior to leukapheresis and lymphodepletion. Subject who has asymptomatic CNS metastatic disease without associated edema, shift, requirement for steroids or anti-seizure medications are eligible. If such a subject receives SRS or WBRT, a minimum period of 2 weeks needs to lapse between the therapy and lymphodepletion. Patients with leptomeningeal disease or carcinomatous meningitis are NOT eligible.
  8. Subject has any other active malignancy besides the tumor under study within 3 years prior to Screening (prior to leukapheresis and prior to lymphodepletion). Exceptions: adequately treated malignancies not likely to require therapy (e.g., completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma). Subjects must be in complete remission from prior malignancy in order to be eligible to enter the study.
  9. Subject has an electrocardiogram (ECG) showing clinically significant abnormality at Screening or showing an average QTc interval ≥450 msec in males and ≥470 msec in females (≥480 msec for subjects with bundle branch block [BBB]) over 3 consecutive ECGs.
