Inclusion Criteria:

             defined as at least one target lesion that can be measured in at least one dimension
             (longest diameter to be recorded) as >= 10 mm, unless lymph node in which case short
             axis must be >= 15 mm. Baseline imaging (for example diagnostic computed tomography
             [CT] chest/abdomen/pelvis and imaging of the affected extremity as appropriate), brain
             imaging (magnetic resonance imaging [MRI] or CT scan) must be obtained within 45 days
             of prior to start of first planned FH-MAGEA1-A2TCR infusion. MRI can be substituted

             eligible for study only after treatment with targeted therapies for those mutations
             have been offered or received. Patients with urothelial carcinoma who are candidates
             for enfortumab vedotin (enfortumab vedotin-ejfv) will be eligible for study after

             still be considered for participation, at discretion of the sponsor and in
             consultation with the investigator. Similarly, should an investigator determine that a
             biopsy cannot be performed safely for clinical reasons biopsies may be cancelled or
             retimed after confirming plan with the sponsor

          -  Participants must be at least three weeks from last systemic treatment: At least 3
             weeks must have passed since any: immunotherapy (for example, T-cell infusions,

             cancer treatment, other investigational agents. There is no washout period for
             radiation, so long as radiated lesion is not the lesion being evaluated for RECIST
