|Official title||A Pilot Pharmacokinetic, Pharmacodynamic and Feasibility Study of Sorafenib in Combination With Cytarabine and Clofarabine in Patients With Refractory or Relapsed Hematologic Malignancies|
|Principal investigator||Hiroto Inaba, MD, PhD|
|Description||Research is performed in patients with age of ≥ 0 months old and < 31 years old. In course 1, sorafenib will be given orally (PO) on days 1 to 7. Pharmacokinetic studies on days 1 and 7 and pharmacodynamic assessment on day 8 will be performed. Inter-patient dose escalation or de-escalation of clofarabine and sorafenib will be performed based on tolerability and toxicity. On days 8 to 12, clofarabine and cytarabine will be administered intravenously (IV) without concurrent twice daily sorafenib. Sorafenib will then be given on days 15 to 28 (14 days). Cytarabine and clofarabine may be given before day 8 when the treating physician feels it is necessary after consulting with the primary investigator based on the participant's clinical condition (e.g. disease progression). Intrathecal (IT) methotrexate (age-adjusted doses) with leucovorin rescue (24 and 30 hours after IT therapy) can be given on day 8. Participants with central nervous system (CNS) disease can receive IT therapy weekly until the cerebrospinal fluid (CSF) becomes free of leukemia (minimum of 4 doses). Triple intrathecal therapy with methotrexate, hydrocortisone and cytarabine is allowed other than day 8 therapy. Response evaluation will be performed on day 22 (or 15 days after initiation of cytarabine and clofarabine) in the first course. One course of therapy will be for 28 days unless disease progression is seen. Participants may receive subsequent courses (up to 5 courses) if there is no disease progression or unacceptable toxicity. Sorafenib is given on days 1 to 7 and 15 to 28 in subsequent courses, and cytarabine with or without clofarabine will be administered starting on days 8 to 12 (clofarabine can be removed after course 2).|
