Inclusion Criteria

-INCLUSION CRITERIA:

1. Measurable metastatic melanoma. The diagnosis of metastatic melanoma and positivity
for gp100 will be confirmed by the Laboratory of Pathology of the the National Cancer
Institute (NCI).

2. Patients must be refractory to high dose aldesleukin treatment if they are medically
eligible to receive it. Patients with noncutaneous melanoma are not required to be
refractory to high dose aldesleukin.

3. gp100:154-162 reactive peripheral blood lymphocytes derived from a

leukapheresis.

4. HLA-A*0201 positive.

5. Greater than or equal to 18 years of age.

6. Willing to practice birth control during treatment and for four months after
receiving the preparative regimen.

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 Eastern Cooperative Oncology Group (ECOG) 0 or 1 for
the high dose aldesleukin cohort or ECOG 0, 1 or 2 for the low dose aldesleukin
cohort.

11. Hematology:

- Absolute neutrophil count greater than 1000/mm^3 without support of filgrastim

- Normal white blood cell (WBC) (greater than 3000/mm^3).

- Hemoglobin greater than 8.0 g/dl

- Platelet count greater than 100,000/mm^3.

12. Serology:

- Seronegative for human immunodeficiency virus (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
be less responsive to the experimental treatment and more susceptible to its
toxicities.)

- Seronegative for hepatitis B or hepatitis C.

13. Chemistry:

- Serum alanine aminotransferase (ALT)/aspartate aminotransferase (AST) less than
less 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 2.0 mg/dl, 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 within the past 3 weeks, as
long as all toxicities have recovered to grade 1 or less or as specified in the
eligibility criteria in Section 2.1.1.

16. Six weeks must have elapsed since prior cytotoxic T-lymphocyte antigen 4 (anti-CTLA4)
antibody therapy to allow antibody levels to decline.

17. Patients who have previously received anti-CTLA4 antibody and experienced treatment
must have a normal colonoscopy with normal colonic biopsies.

EXCLUSION CRITERIA:

1. Women of child-bearing potential who are pregnant or breastfeeding because of the
potentially dangerous effects of the preparative chemotherapy on the fetus or infant.

2. Systemic steroid therapy required.

3. For patients receiving high dose IL-2 only: 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.

4. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency
Disease).

5. 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.)

6. History of severe immediate hypersensitivity reaction to any of the agents used in
this study.

7. The following patients will be excluded from the high-dose IL-2 arm (but will be
eligible for the low-dose arm):

1. History of coronary revascularization or ischemic symptoms

2. Any patient known to have an left ventricular ejection fraction (LVEF) less than
or equal to 45%.

3. Documented LVEF of less than or equal to 45% 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

- Age greater than or equal to 60 years old

4. Documented forced expiratory volume 1 (FEV1) less than or equal to 60% predicted
tested in patients with:

- A prolonged history of cigarette smoking (20 pk/yrs of smoking)

- Symptoms of respiratory dysfunction
