Zusammenfassung
Purpose The adoptive transfer of in vitro generated tumor antigen-specific cytotoxic T lymphocytes (CTL) provides a promising approach to the immunotherapy of cancer. A phase I study was conducted to test the feasibility, safety, and survival of adoptively transferred Melan-A-specific CTL lines in melanoma patients. Patients and Methods Eleven HLA-A2(+) patients with metastatic melanoma received at least three intravenous infusions of Melan-A -specific CTL at 2-week intervals. CTL were generated by four rounds of in vitro stimulation of purified CD8(+) peripheral blood lymphocytes with autologous dendritic cells pulsed with an HLA-A2 binding Melan-A peptide. Each T-cell infusion was accompanied by a 6-day course of low-dose interleukin-2. Results A total of 52 T-cell infusions were administered, averaging 2.1 x 10(8) Melan-A -specific CTL per infusion. Clinical adverse effects were mild and consisted of chills and low-grade fever in seven of 11 patients. Clinical and immunologic responses revealed an antitumor response in three of 11 patients ( one complete regression, one partial regression, one mixed response), an elevated frequency of circulating Melan-A tetramer(+) T cells up to 2 weeks in all the patients with a maximal frequency of 2% of total CD8(+) T cells, an increase in eosinophils to up to 50% in seven of 11 patients, and a selective loss of Melan-A expression in lymph node metastases in two evaluated patients after T-cell transfer. Conclusion Our data indicate that the adoptive transfer of antigen-specific T cells in melanoma patients can induce clinical tumor-specific immune responses without major adverse effects.
