Detailed Description
OUTLINE:
This is a phase I, dose escalation study of FH-MagIC TCR-T cells followed by a phase II study.
LYMPHODEPLETION: Patients receive cyclophosphamide intravenously (IV) and fludarabine IV on days -4, -3, and -2 before each T-cell infusion.
T-CELL INFUSION: Patients receive FH-MagIC TCR-T cells IV over 15-20 minutes. Six to twelve weeks after first T-cell infusion, patients with progressive disease and non-persisting transgenic TCR T cells may receive a second T-cell infusion.
In the Phase 2 portion of the study, atezolizumab will be administered as standard of care beginning 24-72 hours after T-cell infusion. Atezolizumab will be given IV every 3 weeks for at least 1 year in the absence of disease progression or unacceptable toxicity. An alternative PD1 inhibitor may be substituted if atezolizumab (preferred) is not available.
After completion of study treatment, patients are followed up annually for 15 years after final infusion of FH-MagIC TCR-T.

Confirmation of diagnosis must be or have been performed by internal pathology review of archival, initial or subsequent biopsy or other pathologic material at Fred Hutchinson Cancer Research Center (FHCRC)/Seattle Cancer Care Alliance (SCCA)/University of Washington Medical Center (UWMC). Patients with TNBC must meet the American Society of Clinical Oncology - College of American Pathologists (ASCO-CAP) definition of negative estrogen, progesterone and HER2 receptor expression. Baseline tissue will be stained to confirm MAGE-A1 expression
- Measurable disease by RECIST 1.1 criteria: Participants must have measurable disease, 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 for CT in patients unable to have CT contrast. Measurable disease is not required for purposes of leukapheresis /cell manufacturing storage for patients who meet HLA and expression criteria but not standard treatment criteria
Previous treatment with standard of care (SOC) Food and Drug Administration (FDA)-approved therapies. Patients with NSCLC who have actionable somatic mutations or alterations in EGFR, ROS1 and ALK with FDA-approved drug therapy options will be 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 prior treatment with enfortumab vedotin-ejfv has been offered or received
* Note: Participants will be eligible to enroll before standard therapy is received in order to expedite leukapheresis/cell manufacturing as long as the aforementioned agent is administered prior to lymphodepletion and/or cell infusion
- Previous treatment with PD-1 axis inhibitor: Patients in Phase I/2 must have been offered or been previously treated with at least one dose of a PD-L1 axis inhibitor (e.g. PD-1 or PD-L1 inhibiting monoclonal antibody such as pembrolizumab, nivolumab, avelumab, atezolizumab, durvalumab). If received, they must have either developed progression or still have detectable disease and not have developed Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher toxicity while on treatment. Patients may have received 1 or more prior systemic regimens for metastatic TNBC or NSCLC. There is no upper limit on prior regimens. Patients may have received prior anti-PD-1/anti-PD-L1 in the neoadjuvant or adjuvant setting

- Patients with active autoimmune disease requiring immunosuppressive therapy are excluded. Case-by-case exemptions are possible with approval by principal investigator (PI)
- Prior solid organ transplant or allogenic hematopoietic stem cell transplant: Kidney transplant patients will be considered on a case-by-case basis requiring discussion with PI. If kidney transplant, patient must have dialysis access, dialysis plan, supportive nephrologist, willingness to stop transplant immunosuppression, and express understanding that rejection is possible outcome. Dialysis or costs related to transplant kidney will not be supported by the study. Participants having had any other solid organ transplants will be excluded, as will those with any history of allogeneic stem cell transplant
