Combined Therapy With Valproic Acid, All-trans Retinoic Acid (ATRA) and Cytarabine in Human Acute Myelogenous Leukemia (AML) - Full Text View

Sponsor:	University of Bergen
Information provided by:	University of Bergen
ClinicalTrials.gov Identifier:	NCT00995332

Purpose

Hypothesis: Combined treatment with valproic acid and ATRA can be used to achieve disease stabilization for a subset of patients with acute myelogenous leukemia (AML), and this effect can be improved without serious toxicity by adding low-dose cytarabine to this treatment.

Adult patients >18 years of age who can be included:

Elderly patients who cannot achieve standard chemotherapy, patients with relapsed or resistant AML.

Treatment: Combined therapy with:

Valproic acid, continuous therapy until disease progression ATRA, oral therapy for 14 days every three months Low-dose cytarabine 10 mg/m2 up to 10 injections during week 2 and 3, repeated every 3 months.

Condition	Intervention	Phase
Acute Myelogenous Leukemia	Drug: Cytarabine, all-trans retinoic acid, valproic acid	Phase I Phase II

Study Type:	Interventional
Study Design:	Treatment, Non-Randomized, Open Label, Uncontrolled, Single Group Assignment, Safety/Efficacy Study
Official Title:	Treatment of Acute Myelogenous Leukemia With the Histone Deacetylase Inhibitor Valproic Cid in Combination With All-trans Retinoic Acid (ATRA) and Low Dose Cytarabine

Arms	Assigned Interventions
ATRA+valproc acid+low-dose cytarabine: Experimental	Drug: Cytarabine, all-trans retinoic acid, valproic acid ATRA: 22.5 mg/m2 twice daily for 2 weeks every third month Valproic acid: continuous therapy, dosage guided by serum levels Cytarabine: 10 mg/m2 once daily for up to 10 days every third month

Detailed Description:

Patients to be included:

Elderly patients (>60 years of age) or other patients unfit for conventional intensive chemotherapy with newly diagnosed acute myelogenous leukemia (AML).
Adult patients of any age (>18 years of age) with relapsed or resistant AML who cannot receive conventional therapy.

Treatment:

Valproic acid to be started on day 1 as continuous therapy until disease progression.

ATRA administered from day 8 orally as 22.5 mg/m2 twice daily for 14 days, repeated every third month.

Low-dose cytarabine 10 mg/m2 from day 14 and continued as daily injections for up to 10 days, repeated every third month.

Supportive therapy is given according to the hospitals general guidelines.

Followup: The first 2 days treatment in hospital, later regular out-patient treatment. Controls will include clinical examination, peripheral blood parameters (including serum valproic acid levels), bone marrow samples.
