A Phase 2, Single-Center, Open Label Study of Autologous, Adoptive Cell Therapy Following a Reduced Intensity, Non-myeloablative, Lymphodepleting Induction Regimen in Metastatic Urothelial Carcinoma Patients

This is an interventional treatment trial for Metastatic Urothelial Carcinoma focused on measuring Urothelial cancer, Tumor infiltrating lymphocytes, Cellular therapy Read More

Inclusion Criteria:

1. Histologically confirmed Urothelial Carcinoma
2. Progressed on first line platinum-based chemotherapy and on second line immunotherapy or targeted therapy (FGFR inhibitor)
3. Measurable metastatic Urothelial Carcinoma with at least one lesion that is resectable for TIL generation.
4. Patients with one or more brain metastases less than 1 cm each, and any patients with 1 or 2 brain metastases greater than 1 cm must have been treated and stable for 4 weeks.
5. Greater than or equal to 18 years of age.
6. Willing to practice birth control from the start of chemotherapy until 120 days after release from the hospital.
7. Life expectancy of greater than three months
8. Willing to sign a durable power of attorney
9. Able to understand and sign the Informed Consent Document
10. Clinical performance status of ECOG 0 or 1

11. Hematology:

    • Absolute neutrophil count greater than 1000/mm3 without support of filgrastim
    • Normal WBC ( > 3000/mm3).
    • Hemoglobin greater than 8.0 g/dL
    • Platelet count greater than 100,000/mm3

12. Serology:

    • Seronegative for HIV antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune competence and thus can be less responsive to the experimental treatment and more susceptible to its toxicities.)
    • Seronegative for Hepatitis B or Hepatitis C. (patients who recovered from previous infection and have no detected HBSAg or HCV RNA are allowed).

13. Chemistry:

    • Serum ALT/AST less than three times the upper limit of normal (ULN).
    • Serum creatinine less than or equal to 1.6 mg/dL
    • Total bilirubin no more than x1.5 times the ULN, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3 mg/dL.
14. Negative pregnancy test in women of child bearing potential because of the potentially dangerous effects of the preparative chemotherapy on the fetus.
15. More than four weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen, and patients' toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo). Patients may have undergone minor surgical procedures with the past 3 weeks, as long as all toxicities have recovered to grade 1 or less.

Exclusion Criteria:

1. Upper tract Urothelial Carcinoma
2. History of nephrectomy
3. Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the non-myeloablative, lymphodepleting induction regimen on the fetus or infant.
4. Systemic steroid therapy required (patients that require replacement therapy for adrenal insufficiency may be enrolled if steroid treatment dose do not exceed 10 mg of prednisone or equivalent).
5. Active systemic infections, coagulation disorders or other active major medical illnesses of the cardiovascular, respiratory or immune system, as evidenced by a positive stress thallium or comparable test, myocardial infarction, cardiac arrhythmias, obstructive or restrictive pulmonary disease.
6. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease and AIDS).
7. Opportunistic infections (the experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities.)
8. History of severe immediate hypersensitivity reaction to any of the agents used in this study, including history of an anaphylactic reaction to penicillin or gentamicin
9. History of coronary revascularization or ischemic heart disease.
10. Any patient known to have an LVEF less than or equal to 50%.
11. Documented LVEF of less than or equal to 50% tested in patients with clinically significant atrial and/or ventricular arrhythmias including but not limited to: atrial fibrillation, ventricular tachycardia, second- or third-degree heart block
12. Documented FEV1 and DLCO (relative to predicted) less than or equal to 60%
