This study tested whether an antisense drug called AEG35156 can be given safely to patients with acute myeloid leukemia (AML). The drug is designed to lower levels of a protein called XIAP so that cancer cells become more sensitive to chemotherapy (ara-C and idarubicin). This Phase 1/2 trial enrolled patients with refractory or relapsed AML, excluding those with acute promyelocytic leukemia (APL).
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria * Subjects with relapsed or refractory AML, except those with APL (acute promyelocytic leukemia), that are about to receive their initial treatment for first relapse after an initial CR that lasted less than 6 months or for primary refractory AML that have an expected complete response rate ≤20%. The initial diagnosis of AML has to be based on the presence of \> 10% blasts in marrow or blood, and the diagnosis of relapsed/refractory AML based on the presence of either \> 10% blasts in marrow or blood or 5-10% blasts in either site together with cytopenia (Hb \< 10 g/dL, or platelets \< 100,000 /uL, or neutrophil count \< 1000 /uL). * Peripheral AML blast count \< 50,000 /uL that is not projected to rise above 50,000 /uL within 5 days of beginning treatment. * Subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of ≤2. * Subjects must be \>18 years old. * Male, or female subjects who are post-menopausal (amenorrhagic for at least 12 months), or surgically or biologically sterile. Females of childbearing potential with a negative serum pregnancy test 72-96 hours prior to the 1st infusion in the study and using adequate forms of contraception for the duration of the study, including 30 days after the last treatment. Adequate methods of contraception should be used by both male and female subjects. * Subjects must have adequate organ and immune function as indicated by the following laboratory values: * Parameter Laboratory Values * Serum creatinine; \<2.0mg/dL * Total Bilirubin \<2.0mg/dL * AST (SGOT) and ALT (SGPT) \<3 X ULN \* \*ULN: Institution's upper limit of normal. * The subject must understand and be able and willing and likely to fully comply with study procedures, including scheduled follow-up, and restrictions. * The subject, or the subject's legal guardian, must have given written personally signed and dated informed consent to participate in the study, in accordance with the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) Guidelines, before completing any study related procedures. Exclusion Criteria * Clinical evidence of active CNS leukemic involvement. * Patients with left-ventricular ejection fractions \<50%. * Active and uncontrolled infection. Patients with an infection that are under active treatment with antibiotics and whose infections are controlled may be entered to the study. * Current evidence of invasive fungal infection (blood or tissue culture). * Current evidence of an active second malignancy except for non-melanoma skin cancer. * Uncontrolled medical problems, unrelated to the malignancy, or of sufficient severity that in the opinion of the investigator, impair a subject's ability to give informed consent or unacceptably reduce the safety of the proposed treatment. * Neurological or psychiatric disorders that would interfere with consent or study follow-up. * Known or suspected intolerance or hypersensitivity to the study materials \[or closely related compounds\] or any of their stated ingredients. * History of alcohol or other substance abuse within the last year. * Use of another investigational agent or participation in a clinical trial within the last 14 days prior to enrolment. Subjects who have used a previous AS agent for at least 90 days will be excluded. * Female subjects who are pregnant or lactating, or females with a positive pregnancy test at screening must be excluded. * Subjects that have previously been enrolled into this study and subsequently withdrawn must also be excluded.
