Primary Outcome Measures:
  • To determine the maximum tolerated dose (MTD) of 188Re-PTI-6D2 in patients with metastatic melanoma [ Time Frame: Daily/Weekly/Monthy ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • to determine safety and tolerability; dose-limiting toxicities; evaluate the anti-tumor activity; to evaluate the HAMA response; and, to further characterize the pharmacokinetics, biodistribution, and dosimetry of 188Re-PTI-6D2 [ Time Frame: Daily/Weekly/Monthly ] [ Designated as safety issue: Yes ]

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients must have histologically or clinically confirmed malignant melanoma of one of the following stages (according to 2002 American Joint Committee on Cancer criteria: Appendix C): Unresectable Stage III disease or Stage IV disease
  • Patients must have measurable disease as defined by at least one target lesion ≥ 10 mm by spiral CT scan or ≥ 20 mm by conventional techniques
  • Males or females ≥ 18 years of age
  • Karnofsky performance status ≥ 60% (see Appendix D)
  • Life expectancy of greater than three months
  • Failure to respond to other therapy
  • At least 4 weeks since prior chemotherapy or radiation therapy and at least one week since IL-2 therapy
  • Patients must not have significant organ and marrow dysfunction as defined by the following Screening laboratory values: Leukocytes ≥ 3,000/mcL; Absolute neutrophil count ≥ 1,500/mcL; Platelets ≥ 50,000/mcL; Total bilirubin ≤ 2.0 × upper limit of normal(ULN); AST(SGOT)/ALT(SGPT) ≤ 3 × ULN or ≤ 6 × ULN if liver metastases present; Creatinine ≤ 2.0 or creatinine clearance ≥ 60 mL/min/1.73 m2 if creatinine > 2.0
  • Patients must have negative screening human anti-murine antibodies (HAMA).
  • Females who are postmenopausal, physically incapable of childbearing, or practicing an acceptable method of birth control. Acceptable methods of birth control include surgical sterilization, hormonal contraceptives, or double-barrier methods (condom or diaphragm with a spermicidal agent or IUD). If practicing an acceptable method of birth control, a negative urine pregnancy test result has been obtained at the Screening Visit
  • Patients must be able to understand study procedures and must sign a written informed consent form prior to entering the study
  • Patients must agree to comply with all treatment procedures and be willing and able to remain at the study site unit for no less than 48 hours after infusion with 188Re-PTI-6D2 or later as determined by the Investigator's clinical judgment

Exclusion Criteria:

  • Patients who have had chemotherapy or radiotherapy within 4 weeks (IL-2 therapy within one week) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
  • Patients who have participated in another investigational drug trial or therapeutic trial within 30 days of the Screening Visit
  • Patients with brain metastases (must be confirmed by contrast-enhanced MRI within 4 weeks of study entry - a CT scan may be substituted for patients who cannot tolerate the MRI procedure)
  • Patients with any ocular disease that, in the opinion of the PI, could lead to an impaired blood-retinal brain barrier: e.g. severe retinal detachment, ocular melanoma or other ocular neoplastic process, or ocular inflammatory disease
  • Patients with a prior parenteral exposure to murine proteins or a history of allergy or hypersensitivity to investigational or approved antibodies
  • HIV-positive patients on combination antiretroviral therapy are ineligible because of increased risk of lethal infections secondary to marrow-suppressive therapy
  • Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients who are pregnant or breast-feeding
  • Patients who are unwilling to reside in the study unit for a minimum of 48 hours after infusion with 188Re-PTI-6D2 or later as determined by the Investigator's clinical judgment, or to cooperate fully with the investigator or site personnel
