Brief summary

This phase IIa trial studies how well guadecitabine works in treating patients with acute myelogenous leukemia and myelodysplastic syndrome that has returned after a period of improvement after allogeneic stem cell transplant. Guadecitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving guadecitabine before the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

Detailed description

PRIMARY OBJECTIVES: I. To determine the complete response (CR) rate of guadecitabine (SGI-110) with or without donor lymphocyte infusion (DLI) either for the treatment of morphologic relapse or the presence of minimal residual disease (MRD) in patients with acute myeloid leukemia or myelodysplastic syndrome after hematopoietic stem cell transplantation in patients with AML and MDS (cohort 1 and 2). II. The relapse-free survival with the use of SGI-110 as maintenance therapy in patients with high risk acute myeloid leukemia or myelodysplastic syndrome after hematopoietic stem cell transplantation (cohort 3). SECONDARY OBJECTIVES: I. To determine the safety and toxicity of SGI-110 with or without DLI in this subject population. II. To evaluate overall response and survival. OUTLINE: Patients receive guadecitabine subcutaneously (SC) once daily (QD) on days 1-5. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive DLI intravenously (IV) over 10-30 minutes on day 6 of cycles 2, 4, and 6 in the absence of disease progression or unacceptable toxicity.
