An open, multicentre non-randomised study was performed to evaluate the activity and toxicity of combination chemoimmunotherapy, consisting of cisplatin, interleukin-2 and interferon-alpha, in metastatic malignant melanoma. Between March 1992 and September 1993, 28 patients with pathologically proven metastatic malignant melanoma, bidimensionally measurable disease and an Eastern Co-operative Oncology Group score < or = 1 were treated with the combination chemoimmunotherapy. The regimen consisted of cisplatin (100 mg/m2 on day 0), interleukin-2 (Proleukin, Chiron, Middlesex, U.K.) 18 x 10(6)IU/m2/d continuous intravenous infusion on days 3-7 and 17-22, with interferon-alpha (Roferon-A, Roche, Hertfordshire, U.K.) 9 x 10(6) U/d subcutaneously on days 3, 5, 7, 17, 19, 21 during the interleukin-2 infusions. The treatment cycle lasted 28 days. Among 27 assessable patients, 5 patients achieved partial responses, for an overall response rate of 18% (95% CI 6-37%). Median progression-free survival was 44 days (range 8-279) and median overall survival was 264 days (range 41-1432). Differential responses were noted in 41% of patients and responses were more frequent in non-visceral disease (skin, lymph node and soft tissue disease) (P = 0.04). These results indicate that differential responses to chemoimmunotherapy are common in patients with metastatic melanoma. This may account for the broad range of response rates reported in the literature.

A recombinant human IL-2 analog (rIL-2, Proleukin) is currently being evaluated for clinical benefit in HIV infected patients. It is approved for therapy of patients with metastatic melanoma and renal cell carcinoma. Treatment of cancer patients with rIL-2 results in durable responses but is associated with life-threatening toxicity, which limits its use to patients in relatively good health. Antitumor efficacy associated with rIL-2 therapy are hypothesized to be mediated by distinct types of cells that express structurally different forms of the IL-2 receptor. This hypothesis suggests that it might be possible to engineer an IL-2 variant addressing the risks associated with the therapeutic use of IL-2. In this article, we review the clinical experience with IL-2 and its analogs, the evidence that different IL-2 receptors may dissociate efficacy and toxicity, and describe the generation of a novel IL-2 variant with the potential for a superior therapeutic index.

Interleukin-2 (IL-2, Proleukin) is one of the most effective agents in the treatment of metastatic renal cell carcinoma and metastatic melanoma. High-dose IL-2 therapy produces overall response rates of 15% to 20%; however, it is associated with significant toxicities that affect essentially every organ system. Although IL-2-related toxicities are usually reversible with therapy discontinuation, alternative IL-2 regimens have been evaluated. Several phase II studies have demonstrated that administering lower doses of IL-2 by IV bolus or continuous IV infusion or subcutaneously produces overall response rates similar to those with high-dose IL-2 therapy; however, randomized clinical trials have not yet been completed. In renal cell carcinoma, combining IL-2 with interferon alfa (Intron A, Roferon-A) or chemotherapy agents produces similar or increased overall response rates compared with the response rates of IL-2 alone, with no survival advantage. Combination IL-2 regimens in metastatic melanoma patients have produced variable results. The most promising regimens have included various IL-2-based biochemotherapy regimens in other patients. Randomized studies confirming the superiority of these regimens over high-dose IL-2 therapy are needed.

Aldesleukin is a human recombinant interleukin-2 product. It also is known as interlukin-2 and Proleukin in the United States. It is indicated for the treatment of adults with metastatic renal cell carcinoma as well as for adults with metastatic melanoma. However, its use has been limited because of severe systemic toxicity. There have been no reports of aldesleukin producing a hypersensitivity reaction. This is the first reported case of an immediate systemic hypersensitivity reaction occurring after aldesleukin administration confirmed by enzyme-linked immunosorbent assay for specific immunoglobulin E against aldesleukin.

The results of treatment for metastatic melanoma remain disappointing. Single-agent chemotherapy produces response rates ranging from 8% to 15%, and combination chemotherapy, from 10% to 30%. However, these responses are usually not durable. Immunotherapy, particularly high-dose interleukin (IL)-2 (Proleukin), has also shown a low response rate of approximately 15%, although it is often long-lasting. In fact, a small but finite cure rate of about 5% has been reported with high-dose IL-2. Phase II studies of the combination of cisplatin-based chemotherapy with IL-2 and interferon-alfa, referred to as biochemotherapy, have shown overall response rates ranging from 40% to 60%, with durable complete remissions in approximately 8% to 10% of patients. Although the results of the phase II single-institution studies were encouraging, phase III multicenter studies have reported conflicting results, which overall have been predominantly negative. Various factors probably explain these discrepancies including different biochemotherapy regimens, patient selection, and, most importantly, "physician selection." Novel strategies are clearly needed, and the most encouraging ones for the near future include high-dose IL-2 in combination with adoptive transfer of selected tumor-reactive T cells after nonmyeloablative regimens, BRAF inhibitors in combination with chemotherapy, and the combination of chemotherapeutic agents and biochemotherapy with oblimersen sodium (Genasense).
