Melanoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview
Interleukin-2 (IL-2) was approved by the FDA in 1998 on the basis of durable complete response (CR) rates in a minority of patients (0% –8%) with previously treated metastatic melanoma in eight phase I and II studies. No improvement in OS has been demonstrated in randomized trials.
Dacarbazine (DTIC) was approved in 1970 based on overall response rates. Phase III trials indicate an overall response rate of 10% to 20%, with rare CRs observed. An impact on OS has not been demonstrated in randomized trials.[10,11,12,13,14] Temozolomide, an oral alkylating agent, appeared to be similar to DTIC (intravenous administration) in a randomized phase III trial with a primary endpoint of OS; however, the trial was designed for superiority, and the sample size was inadequate to prove equivalency.
Patients with all stages of melanoma may be considered candidates for ongoing clinical trials. Information about ongoing clinical trials is available from the NCI Web site.
