About

This is a phase 1, dose escalation study of Plerixafor in combination with granulocyte-colony stimulating factor , Daunorubicin and Cytarabine in adults patients with relapsed acute myeloid leukemia .

Full description

The Primary objective is to determine the maximal tolerated dose and Recommended Phase 2 Dose of plerixafor when used in combination with granulocyte-colony stimulating factor, Daunorubicin and Cytarabine during induction therapy Then determine the tolerability of plerixafor administered in combination with G-CSF and cytarabine during consolidation therapy.

Enrollment: 11 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
