Patients with relapse of acute leukemia often only receive supportive therapy. Our hypothesis is that a combination therapy can stabilize the disease for patients with early relapse after allogeneic stem cell transplantation. The investigators will combine 5-azacitidine 100 mg daily subcutaneously (days 1-3), valproic acid (continuous therapy from day 1), All-trans retinoic acid (days 1-14) and hydroxurea (continuous treatment from day 15 of first cycle. Azacitidine and ATRA can be repeated with 5 weeks intervals, donor leukocyte infusions on day 10 is allowed from the second cycle.

Condition Intervention Phase
Acute Myeloid Leukemia Drug: Combined use of azacitidine, valproic acid, hydroxurea and eventually donor leukocyte infusions. Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Treatment of Relapsed Acute Leukemia After Allogeneic Stem Cell Transplantation: Disease Stabilization Through Chemotherapy, Immunomodulatory Treatment and Immunotherapy
