Show details

- Patients with prior treatment with gemtuzumab ozogamicin (GO).

- Patients with prior history of VOD/SOS.

- Prior HSCT is not allowed, if it was conducted within 2 months prior to study
enrollment.

- Patients with known active central nervous system (CNS) leukemia.

- Uncontrolled or active infectious status.

- Uncontrolled cardiac dysrhythmias of NCI CTCAE Grade 2, uncontrolled atrial
fibrillation of any grade.

- Sero?positivity to human immunodeficieny virus (HIV).

- Active hepatitis B or hepatitis C infection

- Chemotherapy, radiotherapy, or other anti?cancer therapy (except hydroxyurea as
cytoreduction) within 2 weeks prior to enrollment in the study.

- Major surgery within 4 weeks prior to enrollment.

- QTc interval >470 milliseconds (msec) using the Fridericia (QTcF), family or personal
history of long or short QT syndrome, Brugada syndrome or known history of QTc
prolongation, or Torsade de Pointes (TdP).

- The use of medications known to predispose to Torsades de Pointes within 2 weeks prior
to enrollment

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to gemtuzumab ozogamicin (GO).

Evaluating QTc, PK, Safety of Gemtuzumab Ozogamicin (GO) in Patients With CD33+ R/R AML
A Single Arm, Open-label, Phase 4 Study Evaluating Qt Interval, Pharmacokinetics, And Safety Of Gemtuzumab Ozogamicin (Mylotarg (Trademarker)) As A Single-agent Regimen In Patients With Relapsed Or Refractory Cd33-positive Acute Myeloid Leukemia
This is a single?arm, open?label, Phase 4 study evaluating the effect of GO on the QTc, pharmacokinetics, safety, and immunogenicity of GO as a single?agent monotherapy in adult and pediatric patients with relapsed or refractory CD33?positive AML.
This is a single?arm, open?label, Phase 4 study evaluating the effect of GO on the QTc, pharmacokinetics, safety, and immunogenicity of GO as a single?agent monotherapy in adult and pediatric patients with relapsed or refractory CD33?positive AML. Approximately 50 adult (age >=18 years) and 6 pediatric (12 years =< age =< 17 years) patients who satisfy the study eligibility criteria will be enrolled. Enrolled patients will receive GO 3 mg/m2 up to 2 cycles on Days 1, 4, and 7 at each cycle. The impact of GO on VOD/SOS in the context of previous and subsequent HSCT will also be assessed. Patients enrolled in the study will receive three doses of GO 3 mg/m2 (up to one vial) as a 2?hour intravenous infusion on Cycle 1 Days 1, 4, and 7. A second cycle of GO 3mg/m² (up to one vial) on Cycle 2 Days 1, 4, and 7 will be allowed at the investigator's discretion for patients who meet the following criteria after Cycle 1: Bone marrow with a decrease of blast percentage to at least 25% or a decrease of pretreatment blast percentage by at least 50%; and Blood count with neutrophils >=1,000/µL, and platelets >=50,000/µL, except in patients with the bone marrow blasts >=5%, the decrease in neutrophils and platelets thought to be due to the underlying leukemia. After GO treatment, subsequent anticancer therapy such as consolidation or conditioning regimen and/or HSCT could be considered at the investigator's discretion. A minimum interval of 2 months is recommended between the last dose of GO and HSCT.
