A Study of Clofarabine in Japanese Patients With Acute Myeloid Leukemia (AML)

2014-07-23 21:09:47 | BioPortfolio

Summary

This study is sponsored by Genzyme Japan K.K. The purpose of this study is to assess the safety, tolerability and pharmacokinetics of Clofarabine (JC0707) intravenously administered to Japanese adult patients with newly diagnosed or relapsed/refractory AML at 20, 30, and 40 mg/m2/day on a 5-day dose schedule

Description

This is a Phase I, open-label, multi-center study of Clofarabine administered to Japanese patients with AML who are relapsed/refractory or elderly untreated AML for whom standard induction chemotherapy is unlikely to be of benefit.

Cohort 1 will receive 20 mg/m2/day of Clofarabine once daily for five consecutive days, Cohort 2 will receive 30 mg/m2/day, and Cohort 3 will receive 40 mg/m2/day. Patients will receive one cycle as a rule. However, if there is evidence of some hematologic response after one cycle of treatment with Clofarabine, patients may receive up to a maximum of three cycles. If patients fail to achieve CR or CRp after two cycles of treatment with Clofarabine, further dosing for such patients should be stopped.

Three patients constituting a cohort will receive Clofarabine and will then be assessed for dose limiting toxicities (DLT) at Cycle 1. If none of these three patients develops DLT, the next cohort will be introduced. If one of them develops DLT, three new patients will be added to the cohort, so that six patients in total are included in the tolerability assessment. In this case, treatment of the next cohort is allowed only in the case the number of patients who develop DLT is still one in this six-patient cohort. If two of the six patients develop DLT, however, the tolerability is ruled out. However, if two DLTs are observed at the 20mg/m2/day dose cohort, new patients will be enrolled at cohort -1 15mg/m2/day; and if no more than one of six patients in the cohort develop DLT, it will be considered as the last cohort for this study.

Medical and Biotech [MESH] Definitions

A rare acute myeloid leukemia characterized by abnormal EOSINOPHILS in the bone marrow.

An acute myeloid leukemia in which abnormal PROMYELOCYTES predominate. It is frequently associated with DISSEMINATED INTRAVASCULAR COAGULATION.

An acute leukemia exhibiting cell features characteristic of both the myeloid and lymphoid lineages and probably arising from MULTIPOTENT STEM CELLS.

Conditions in which the abnormalities in the peripheral blood or bone marrow represent the early manifestations of acute leukemia, but in which the changes are not of sufficient magnitude or specificity to permit a diagnosis of acute leukemia by the usual clinical criteria.

An acute myeloid leukemia in which 80% or more of the leukemic cells are of monocytic lineage including monoblasts, promonocytes, and MONOCYTES.
