Conditions: Acute Myeloid Leukemia With 11q23-abnormality in Relapse
Allocation: NON_RANDOMIZED | Intervention model: SINGLE_GROUP
Enrollment: 23
Healthy volunteers: no

Brief summary:
The purpose of the study is to first determine if temozolomide plus vorinostat in combination can control relapsed or refractory acute myeloid leukemia (AML) and determine if this combination can be safely taken. The study will look at the side effects of the Temozolomide plus Vorinostat in combination and whether the treatment schedule is tolerated.

Detailed description:
The primary endpoint of the study is to determine the clinical efficacy as determined by the rate of morphological complete remission, of 2 different treatment regimens of temozolomide and vorinostat administered to 2 distinct groups of participants patients with AML and poor prognostic features. Participants will be allocated to treatment on the basis of O6-methylguanine DNA methyltransferase (MGMT) promoter methylation status.

Arms:
arm 1: Participants with methylated O6-methylguanine DNA methyltransferase (MGMT) promoter, ie, expected to have no expression of MGMT protein, will be assigned into Group 1, and will receive vorinostat 500 mg orally 3 times daily for 3 days, followed by conventional doses of temozolomide (200 mg/m2 for 7 days). arm 2: Participants with non-methylated O6-methylguanine DNA methyltransferase (MGMT) promoter, ie, expected to have expression MGMT protein, will be assigned to into Group 2, and will initially receive daily, low doses (protracted dose schedule) of temozolomide (100 mg/m2) for 14 days in an attempt to inactivate MGMT activity. Following the protracted dose schedule, participants will receive vorinostat 500 mg orally 3 times daily for 3 days, followed by conventional doses of temozolomide (200 mg/m2 for 7 days).

Interventions: intervention 1: Temozolomide intervention 2: Vorinostat
Intervention descriptions: intervention 1: An alkylating agent administered for induction per standard of care at 200 mg/m²/day for 7days. intervention 2: A synthetic hydroxamic acid derivative with antineoplastic activity administered for both groups at 500 mg orally 3 times daily for 3 days prior to Temozolomide 200 mg/m²/day.
