Abstract

Background: This randomized phase III trial was designed to demonstrate the superiority of autologous peptide-loaded dendritic cell (DC) vaccination over standard dacarbazine (DTIC) chemotherapy in stage IV melanoma patients. Patients and methods: DTIC 850 mg/m2 intravenously was applied in 4-week intervals. DC vaccines loaded with MHC class I and II-restricted peptides were applied subcutaneously at 2-week intervals for the first five vaccinations and every 4 weeks thereafter. The primary study end point was objective response (OR); secondary end points were toxicity, overall (OS) and progression-free survival (PFS). Results: At the time of the first interim analysis 55 patients had been enrolled into the DTIC and 53 into the DC-arm (ITT). OR was low (DTIC: 5.5%, DC: 3.8%), but not significantly different in the two arms. The Data Safety & Monitoring Board recommended closure of the study. Unscheduled subset analyses revealed that patients with normal serum LDH and/or stage M1a/b survived longer in both arms than those with elevated serum LDH and/or stage M1c. Only in the DC-arm did those patients with (i) an initial unimpaired general health status (Karnofsky = 100) or (ii) an HLA-A2+/HLA-B44− haplotype survive significantly longer than patients with a Karnofsky index

Only in the DC-arm did those patients with (i) an initial unimpaired general health status (Karnofsky = 100) or (ii) an HLA-A2+/HLA-B44− haplotype survive significantly longer than patients with a Karnofsky index <100 (P = 0.007 versus P = 0.057 in the DTIC-arm) or other HLA haplotypes (P = 0.04 versus P = 0.57 in DTIC-treated patients). Conclusions: DC vaccination could not be demonstrated to be more effective than DTIC chemotherapy in stage IV melanoma patients. The observed association of overall performance status and HLA haplotype with overall survival for patients treated by DC vaccination should be tested in future trials employing DC vaccines

Abstract

Stage melanoma IV has a poor prognosis, with a median survival time between 3 and 11 months from the diagnosis of distant metastases. Response rates in first-line regimens are around 20%. To date, no second-line treatment has been established. We performed a randomized, multicentre, second-line clinical phase II study of paclitaxel either as monotherapy or combined with carboplatin given on an outpatient basis. In arm A, paclitaxel was administered at a dose of 100 mg/m2 intravenously on day 1 each week for 6 weeks. In arm B, paclitaxel was administered at a dose of 80 mg/m2 intravenously followed by carboplatin 200 mg/m2 on day 1 each week for 6 weeks. The next cycle was administered after a 2 week intermission. The response rate, survival time, time-to-progression and toxicity were assessed in both arms. The study was stopped after 40 patients because the overall response rate was below 10% in both arms. The median survival time after initiation of second-line treatment was 209 days (+/- 196 days) for patients treated with paclitaxel only, and 218 days for those treated with paclitaxel/carboplatin. The median time-to-progression was around 56 days in both arms. Two partial responses were observed after 16 weeks, lasting for 8 and 12 weeks, respectively. Although both treatment modalities were well tolerated, haematological toxicity was higher in the combination arm. This is so far the largest second-line clinical phase II study reported in melanoma. However, paclitaxel with or without carboplatin had only limited efficacy, and the combination of these drugs adds significantly to haematological toxicity without improving response or survival rates.
