PURPOSE: In phase I/II trials, the cytotoxic T lymphocyte-associated
antigen-4-blocking monoclonal antibody tremelimumab induced durable responses in
a subset of patients with advanced melanoma. This phase III study evaluated
overall survival (OS) and other safety and efficacy end points in patients with
advanced melanoma treated with tremelimumab or standard-of-care chemotherapy.
PATIENTS AND METHODS: Patients with treatment-naive, unresectable stage IIIc or
IV melanoma were randomly assigned at a ratio of one to one to tremelimumab (15
mg/kg once every 90 days) or physician's choice of standard-of-care chemotherapy
(temozolomide or dacarbazine). RESULTS: In all, 655 patients were enrolled and
randomly assigned. The test statistic crossed the prespecified futility boundary
at second interim analysis after 340 deaths, but survival follow-up continued. At
final analysis with 534 events, median OS by intent to treat was 12.6 months (95%
CI, 10.8 to 14.3) for tremelimumab and 10.7 months (95% CI, 9.36 to 11.96) for
chemotherapy (hazard ratio, 0.88; P = .127). Objective response rates were
similar in the two arms: 10.7% in the tremelimumab arm and 9.8% in the
chemotherapy arm. However, response duration (measured from date of random
assignment) was significantly longer after tremelimumab (35.8 v 13.7 months; P =
.0011). Diarrhea, pruritus, and rash were the most common treatment-related
adverse events in the tremelimumab arm; 7.4% had endocrine toxicities. Seven
deaths in the tremelimumab arm and one in the chemotherapy arm were considered
treatment related by either investigators or sponsor. CONCLUSION: This study
failed to demonstrate a statistically significant survival advantage of treatment
with tremelimumab over standard-of-care chemotherapy in first-line treatment of
patients with metastatic melanoma.
