Intervention/Treatmentcyclophosphamide tumor specific antigen induced cytotoxic lymphocyte fludarabine ...
The primary purpose of this study is to evaluate the safety of TSA-CTL in the treatment of the advanced melanoma.
The secondary purpose of this study is to evaluate preliminarily the effect of TSA-CTL in the treatment of the advanced melanoma.
This study is a Phase 1 clinical trial comprised of two parts. In part one, 9 subjects are assigned to group A,B,C. Dose escalation is used in In group A with no non-myeloablative chemotherapy, group B and group C will undergo a non-myeloablative chemotherapy before the cell infusion. Whether the part 2 of the trial continue is determined by the result of part 1. If continues, 15 subjects will be enrolled into the trial and receive a regimen of immune cell infusion combined with non-myeloablative chemotherapy.
On day 0,TSA-CTL will be infused intravenously on the Patient Care Unit over 20-30 minutes.
Cyclophosphamide 500 mg/m2/day IV in 250 ml on day -5 for one day.
Fludarabine 25 mg/m2/day IVPB daily over 30 minutes on day -5 and -4 for two days.
Cyclophosphamide 500 mg/m2/day IV in 250 ml on day -5 and -4 for two days.
Patients will receive medium dose of lymphodepleting preparative regimen consisting of cyclophosphamide and fludarabine followed by TSA-CTL.
Patients will receive low dose of lymphodepleting preparative regimen consisting of cyclophosphamide and fludarabine followed by TSA-CTL.
Patients will only receive TSA-CTL.

Measurable metastatic melanoma with at least one lesion that is resectable or tumor biopsies for DNA extraction. Patient failed or be intolerant in conventional treatment. Able to understand and sign the Informed Consent Document.Willing to sign a durable power of attorney. Clinical performance status of ECOG 0 or 1 and Life expectancy of greater than six months；able to cooperate to observe adverse reactions and the effect of the treatment. Patients of both genders must be willing to practice birth control from the time of enrollment on this study and for up to twelve months after treatment. Serology：Seronegative for HIV antibody，Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody. Women of child-bearing potential must have a negative pregnancy test because of the potentially dangerous effects of the treatment on the fetus.Hematology：Absolute neutrophil count greater than 1000/mm(3) without the support of filgrastim，WBC greater than or equal to 3000/mm(3)，lymphocyte count greater than or equal to 800/mm(3)，Platelet count greater than or equal to 100,000/mm(3)，Hemoglobin > 9.0 g/dl Chemistry：Serum ALT/AST less than or equal to 2.5 times the upper limit of normal，Serum Creatinine less than or equal to 1.6 mg/dl，Total bilirubin less than or equal to 1.5 mg/dl, except in patients with Gilbert s Syndrome who must have a total bilirubin less than 3.0 mg/dl. 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).Note: Patients may have undergone minor surgical procedures within the past 3 weeks, as long as all toxicities have recovered to grade 1 or less. Eight weeks must have elapsed from the time of any antibody therapy that could affect an anti cancer immune response, including anti-PD1 antibody and anti-CTLA4 antibody therapy, so at the time the patient receives the preparative regimen to allow antibody levels to decline. Exclusion Criteria: Women of child-bearing potential who are pregnant or breastfeeding. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease). Concurrent 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). The medical history of autoimmune disease. Active systemic infections, coagulation disorders or other active major medical illnesses of the cardiovascular, respiratory or immune system. Concurrent systemic steroid therapy(in 4 weeks). History of severe immediate hypersensitivity reaction to any of the agents used in this study. Patients with unstable brain metastases. The choroid melanoma and clear cell sarcoma patients. Negative for expression of MHC molecules.
