Abstract:
:Tricot et al have reported that the nucleoside analog tiazofurin can induce hematologic remissions in patients with chronic myelogenous leukemia in blast crisis (CML-BC). These reports prompted us to begin a derivative, phase II trial of tiazofurin in CML-BC to determine if the promising findings reported by these investigators could be reproduced. In our ongoing trial patients receive tiazofurin by IV infusion (2200-4400 mg/m2 over 1 hr) once every 24-48 hrs for up to 10 days. Each of 3 patients, treated to date on this trial, experienced substantial hematologic responses with normalization of WBC counts and complete or partial clearance of blasts from the blood within 4-11 days of treatment. These responses were relatively brief, in that leukemic blasts reaccumulated in the marrow and blood of patients within 4 weeks following treatment, but were re-induced with subsequent courses of treatment. Of interest, the rates of blast cell reaccumulation appeared to increase progressively following sequential courses of treatment. Tiazofurin, which inhibits IMP-dehydrogenase (IMPDH) and blocks guanine ribonucleotide synthesis, has been shown to increase IMPDH mRNA expression in various cell lines in vitro, as an apparently compensatory response to guanylate deprivation. Studies of IMPDH mRNA expression in the leukemic blasts of CML-BC patients receiving tiazofurin treatment showed that this same phenomenon occurs in vivo. Since IMPDH activity is linked to the proliferative activity of neoplastic cells an amplification of IMPDH message expression induced by tiazofurin may lead to an increased sensitivity of the leukemic clone to cycle active agents.
