Inclusion criteria
The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- Patients with CD33+ AML who have experienced relapse after autologous or allogeneic
HSCT. Flow cytometry, performed at the study site, must demonstrate that the patient
has AML that is CD33 positive, based on local laboratory criteria (Patients with
history of MDS pretransplant will be eligible if their proportion of myeloblasts by
marrow aspirate exceeds 5% at time of evaluation for Gemtuzumab Ozogamicin treatment)

- The patient must be greater than or equal to 60 days post-HCST

- Patients of all ages may be entered in this study

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

- Peripheral white blood count (WBC) greater than or equal to 30,000/uL at the time of
initial Gemtuzumab Ozogamicin administration. (In order to reduce the peripheral blood
count, patients may be treated with Hydroxyurea. Hydroxyurea must be discontinued 24
hours prior to Gemtuzumab Ozogamicin administration.)

- Known active central nervous system (CNS) or testicular leukemia at time of study
entry.

- Prior therapy with anti-CD33 antibodies.

Descriptive Information
Brief Title  ICMJE Study Evaluating Gemtuzumab Ozogamicin in Acute Myelogenous Leukemia After Stem Cell Transplant
Official Title  ICMJE A Dose-Finding Study of the Safety of Gemtuzumab Ozogamicin as Single Agent Treatment of Patients With Relapsed Acute Myelogenous Leukemia After Autologous or Allogenic Hematopoietic Stem Cell Transplant (HSCT)
Brief SummaryThe primary objective of this study is to evaluate the safety of gemtuzumab ozogamicin in relapsed CD33-positive AML patients who received HSCT. If the MTD dose is not reached, 9 mg/m2 will be the maximum tested dose. A secondary objective is to assess efficacy in terms of the number of patients attaining a complete (CR) or morphological (CRp) remission.
