Phase I clinical trial of 13-cis-retinoic acid in myelodysplastic syndromes.
    Cancer treatment reports, 1983, Volume: 67, Issue:11

    13-cis-Retinoic acid (13-cRA) induces maturation and differentiation of neoplastic myeloid cell lines in vitro. We conducted a phase I clinical trial of 13-cRA in patients with myelodysplastic syndromes (MDS), using a single daily oral dose schedule. Seventeen patients with MDS and one each with acute nonlymphoblastic leukemia and chronic myelogenous leukemia in blast crisis were treated with 13-cRA at doses ranging from 20 to 125 mg/m2/day. Hepatotoxicity was dose-limiting and was manifested by hyperbilirubinemia and increased SGOT levels. This effect was seen only at the highest dose level of 125 mg/m2/day and was completely reversible upon cessation of the drug. Other toxic effects were mild, and included cheilosis, hyperkeratosis, stomatitis, and elevation of serum triglyceride levels. Fifteen patients with MDS were evaluable for therapeutic response. Five patients showed improvement in hematologic parameters. These responses included normalization of bone marrow blast count and increases in leukocyte count, platelet count, and/or hemoglobin concentration. Responses were generally not seen until at least 3 weeks of therapy were completed. We conclude that further study of 13-cRA in myelodysplastic syndromes is warranted and recommend that future studies utilize a starting dose of 100 mg/m2.
