title: Phase II study of recombinant human interferon gamma for treatment of cutaneous T-cell lymphoma.
abstract: Recombinant human interferon gamma (rIFN-gamma) was used for the treatment of 16 patients with various stages of cutaneous T-cell lymphoma (CTCL). All patients had been previously treated with standard topical and/or systemic therapies, and some had received experimental treatment with retinoids, recombinant human interferon alfa-2a (rIFN-alpha 2a), or radiolabeled monoclonal antibodies; most patients had an advanced stage of disease. Objective partial responses (PRs) were noted in five patients (31%) and lasted 3 months to greater than 32 months (median, 10 mo). One of these five patients had previously had disease progression after an initial PR with rIFN-alpha 2a. Six other patients (38%) showed minor or mixed responses. The most common side effects of rIFN-gamma included fever, weight loss, mild neutropenia, elevated lactate dehydrogenase, and elevated hepatic transaminases. Additionally, one episode of nephrotic syndrome and one cutaneous allergic reaction were noted. None of the toxic effects were life threatening, and all were reversible. These results suggest that rIFN-gamma has efficacy in the treatment of CTCL refractory to rIFN-alpha 2a.
