Phase II study of YNK01 (1-beta-D-arabinofuranosylcytosine-5'-stearylphosphate), a derivative of cytosine arabinoside, on hematological malignancies was conducted by multi-institutional cooperative group. YNK01 was administered orally at dose of 100-300 mg/body/day for more than 2 weeks. The number of registered and evaluated patients were 211 and 156, respectively. Of 23 patients with acute myelogeneous leukemia (AML), 2 complete response (CR), one partial response (PR) were observed (CR + PR: 13.0%). Hypoplastic leukemia (1/4: 25%), acute unclassified leukemia (1/1: 100%). Of 45 patients with MDS, 2CRs, 6 good response (GR) and 5PRs were observed (CR + PR: 28.9%). AML developing after a prior history of MDS (5/17: 29.4%), CML-BC (2/9: 22.2%). Of 19 patients with CML, 9 achieved CR, 3 achieved PR (63.2%). Of 11 patients with polycythemia vera, 4 achieved CR, 5 achieved PR (81.8%). Of 6 patients with essential thrombocytosis, 2 achieved CR, one achieved PR (50%). The major adverse effects included gastrointestinal toxicities such as nausea, vomiting, anorexia, diarrhea, and elevation of GOT and GPT which were tolerable and reversible. This study indicates that YNK01 is a useful agent against acute leukemia and MDS, especially RAEB, RAEB in T, CMMoL.

A phase II clinical trial on MDS was conducted in a cooperative study with orally administrable ara-C analogue, PLAC, which is resistant to cytidine deaminase and had shown an anti-tumor activity on various experimental tumors by oral route. Fifty MDS (3 RA, 18 RAEB, 11 RAEB-T, 18 RAEB-blast crisis (BC) were treated orally with 100 to 400mg/body of daily PLAC. One good response (GR) and 3 partial responses (PR) were obtained in 18 RAEB, and 2 complete remissions, 1 GR and 1 PR were noted in 11 RAEB-T, while 3 PR were seen in 18 RAEB-BC. Overall CR rates were 4%, GR rates 4% and PR rates 14%. Thus, 22% of MDS responded to oral PLAC. No clear daily dose-response was noted. Response, however, was dependent on the treatment period and was obtained in cases which had been treated for more than 20 days. Besides myelosuppression, side effects were mainly gastrointestinal, and anorexia (32%), nausea/vomiting (30%) and diarrhea (8%) were observed. Oral PLAC seems to be active on MDS which does not necessarily require admission to hospital.

Autologous peripheral blood stem cell transplantation(auto-PBSCT)combined with high-dose chemotherapy has been considered as the standard therapy for relapsed or induction therapy-refractory aggressive lymphomas sensitive to chemotherapy. While various regimens have been applied as the conditioning,none has yet been established as the standard. We have begun to employ high-dose ranimustine,cytarabine,etoposide and cyclophosphamide(MCVAC)regimen. The present study was undertaken to review the efficacy and safety of MCVAC. Regimen: We carried out a retrospective analysis of 20 patients diagnosed as diffuse large B-cell lymphoma. The median follow-up duration of 20 patients was 13.05 months(range, 0.57-49.5 months). The 4-year OS and PFS were 57.8% and 30.2%,respectively. Relapse was the most frequent cause of treatment failure(n=7). The major toxicities were anorexia/nausea(95%),diarrhea (75%),hypokalemia (70%). One patient died of hepatic veno-occlusive disease(VOD). The serious adverse events included hypokalemia,arrhythmia,cerebral hemorrhage,and heart failure(1 case[5%]each). There was 1 case of a late-onset adverse event: therapy-related myelo- dysplastic syndrome/acute myeloblastic leukemia(MDS/AML). MCVAC regimen was concluded as effective and well-toler- ated. However,we should carefully monitored for the possible development of VOD and MDS/AML. Further follow-up is needed to evaluate the long-term efficacy and safety.
