Phase II Study of Flt3 Ligand Alone or in Combination With Melanoma Peptide Immunization in Patients With Metastatic Melanoma or Renal Cell Cancer
Alternate Title flt3L With or Without Vaccine Therapy in Treating Patients With Metastatic Melanoma or Renal Cell Cancer
Objectives I. Evaluate the immunologic and biologic activity of flt3 ligand (Flt3L) alone in patients with metastatic renal cell cancer or HLA-A2.1 negative melanoma. II. Evaluate the immunologic and biologic activity of Flt3L alone or in combination with melanoma peptide immunization (MART-1, gp100:209-217, gp100:280-288, and tyrosinase) in patients with metastatic, HLA-A2.1 positive melanoma. Entry Criteria Disease Characteristics: Histologically proven metastatic melanoma or renal cell cancer Patients receiving melanoma peptide immunizations must be HLA-A2.1 positive Measurable disease Prior/Concurrent Therapy: Biologic therapy: At least 1 month since prior biologic therapy Chemotherapy: At least 1 month since prior chemotherapy Endocrine therapy: No concurrent systemic steroid therapy At least 1 month since prior steroid therapy Radiotherapy: At least 1 month since prior radiotherapy Surgery: Prior surgery allowed Other: Greater than 1 month since prior therapy Patient Characteristics: Age: Not specified Performance Status: ECOG 0-1 Life Expectancy: Greater than 3 months Hematopoietic: WBC at least 3,000/mm3 Platelet count at least 90,000/mm3 No coagulation disorders Hepatic: Bilirubin no greater than 1.6 mg/dL AST and ALT less than 2 times normal Renal: Creatinine no greater than 2 mg/dL Cardiovascular: No major cardiovascular disease Pulmonary: No major pulmonary disease Other: Not pregnant or nursing Negative pregnancy test HIV negative Hepatitis B surface antigen negative No allergic reaction to Montanide ISA-51 No active systemic infection No prior autoimmune disorders Expected Enrollment Approximately 54-96 patients (18-32 per treatment group) will be accrued for this study within 16 months. Outline Patients are assigned to 1 of 3 treatment groups: Group 1 (renal cell cancer): Patients receive Flt3 ligand (Flt3L) subcutaneously (SQ) alone on days 1-14. Group 2 (HLA-A2.1 negative melanoma): Patients receive Flt3L SQ alone on days 1-14. Group 3 (HLA-A2.1 positive melanoma): Patients may receive either Flt3L SQ alone on days 1-14 or in combination with melanoma peptide immunization. Patients may receive melanoma peptide immunization comprised of MART-1 immunodominant peptide, gp100:209-217, gp100:280-288, and tyrosinase peptide emulsified in Montanide ISA-51 SQ on day 12 of Flt3L administration. Treatment repeats every 4 weeks for 2 courses. Patients with no response or minor response may receive 2 additional courses. Patients with disease progression after 1 course are removed from study.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. |
