Phase II trial of prednimustine, L-1031, (NSC-134087) in advanced breast cancer

Abstract
The therapeutic effect of prednimustine was studied in 35 patients with advanced breast cancer resistant to previous cytotoxic and/or endocrine therapy. Response (PR + CR) was obtained in 14 patients (40%) of a median duration of five months. Among the 14 responding patients, 10 were resistant to previous endocrine therapy and chemotherapy, in all cases including alkylating agents, and 4 were resistant to previous endocrine therapy. Hematologic toxicity was rather pronounced, but other toxicities were only moderate.
