What is G-CSF?
• Granulocyte Colony Stimulating Factor
– Glycoprotein
– Growth factor
– Cytokine
• Produced by endothelium, macrophages and
other immune cells
• G-CSF receptor present on precursor cells in the
bone marrow
– Initiates proliferation and differentiation into mature
granulocytes
– Stimulates bone marrow cell release into circulation
Two important G-CSF uses
1.
MOST COMMON: Post chemotherapy febrile
neutropenia
2.
Potent inducer of hematopoietic stem cell
mobilization for stem cell transplantation
Side effects associated with G-CSF

STEM-AMI OUTCOME TRIAL
STUDY OBJECTIVES
To demonstrate that G-CSF in addition to state of the art
treatment is safe and significantly improves clinical
outcome in patients with reduced left ventricular EF
(≤45%) after successful reperfusion for large anterior
acute myocardial infarction
STEM-AMI OUTCOME TRIAL
DESIGN
Phase III, randomized, open label.
1530 Patients (50 centres) will be randomized to standard
therapy + G-CSF or standard therapy alone in 1:1 ratio.
Accrual time 3 years. Follow-up time 2 years.
TREATMENT
FILGRASTIM 5 µg/kg will be administered subcutaneously
bis in die for 6 days (from Day 1 to Day 6), starting within
24 h after PCI and reperfusion.
STEM-AMI OUTCOME TRIAL
PRIMARY EFFICACY END POINT
Clinical outcome will be assessed by the composite endpoint of:
• death or
• recurrence of MI or
• hospitalization due to heart failure
SAFETY ENDPOINTS
• Incidence and severity of bleeding complications
• Incidence of malignancy
• Incidence and intensity of AEs and SAEs
STEM-AMI OUTCOME TRIAL
INCLUSION CRITERIA
• Patients affected by acute anterior STEMI undergoing primary PCI
(or PCI-rescue with persistent occlusion of coronary artery)
• Time symptom-to-balloon ≥3 h and ≤12h (or ≤24 h if symptoms
persist)
• TIMI flow post PCI ≥2
• Evidence of LV dysfunction (EF biplane ≤ 45%) ≤ 24 h after
revascularization
• Men and women aged ≥18 years and ≤ 75 years,
• Informed consent must be signed before proceeding with any study
procedure.
