Phase II clinical trial of recombinant alpha 2b interferon and 13 cis retinoic acid in patients with metastatic melanoma

Abstract

Treatment for metastatic melanoma is limited by low response rates to single- or combination-agent chemotherapy. Recent studies have examined the role of biologic modifiers and differentiating agents. This phase II study examined the efficacy and toxicity of combining alpha-2b-interferon (IFN alpha) and 13 cis retinoic acid (cRA) in the treatment of metastatic malignant melanoma. Thirteen patients were treated with IFN alpha (5 x 10(6) units/m2 three times weekly) and cRA (1 mg/kg per day). One patient with lung and adrenal metastases had a partial response 6 months in duration and two patients had stabilization of lung metastases for 2 months. All other patients had progressive disease. Tox..
