A Phase II, Open-Label Study of Clofarabine in Paediatric Patients With Refractory/Relapsed Acute Lymphoblastic Leukaemia

This study has been completed.

Sanofi Identifier:
First received: June 17, 2009
Last updated: February 10, 2014
Last verified: February 2014
This study is for a population of patients with few or no alternative options that was conducted to determine the response rate to clofarabine. Additionally the study will provide information on the safety profile, impact of overall survival, and impact on remission duration with clofarabine. It is a single arm study and has no comparator.

Condition Intervention Phase
Acute Lymphoblastic Leukemia
Drug: clofarabine
Phase 2

Study Type: Interventional

Primary Outcome Measures:
  • Overall response rate after 1 course or more [ Time Frame: minimum of 1 course and maximum of 12 courses ]

Secondary Outcome Measures:
  • Overall response rate after 2 courses or more [ Time Frame: minimum of 2 courses and maximum of 12 courses ]
  • Rate of response (complete, complete with incomplete blood count recovery, partial) after 1 course or more [ Time Frame: minimum of 1 course and maximum of 12 courses ]
  • Time-to-event parameters including duration of remission and overall survival [ Time Frame: Until death of patient or until end of study treatment for last enrolled patient ]
  • Safety and tolerability [ Time Frame: Until death of patient or until end of study treatment for last enrolled patient ]
  • Number of patients received bone marrow or peripheral blood stem cell transplantation and the time to transplant following commencement of Clofarabine [ Time Frame: Until death of patient or until end of study treatment for last enrolled patient ]
  • Determine pharmacokinetic profile and intracellular triphosphate and levels of clofarabine [ Time Frame: every day during the first course of treatment ]
  • Document the metabolic pathways that may predict Clofarabine sensitivity or resistance [ Time Frame: day 1, day 5, day 6 and day 7 of the first course ]
