Condition(s) targeted: Thrombocytopenia; Thrombosis
Intervention: Argatroban (Drug)
Phase: Phase 4
Sponsored by: Encysive Pharmaceuticals
The purpose of this study is to evaluate the safe and effective dose of Argatroban for
prophylaxis and/or treatment of thrombosis in pediatric patients with current or previous
diagnosis of heparin-induced thrombocytopenia (HIT) and thrombosis syndrome (HITTS), or who
in the opinion of the investigator require alternative anticoagulation due to an underlying

Study design: Treatment, Non-Randomized, Open Label, Uncontrolled, Single Group Assignment, Safety/Efficacy Study
Minimum age: N/A.
Maximum age: 16 Years.
Criteria for Inclusion:
- Males and females ages birth to 16 years,inclusive, at enrollment. For neonates, the
minimum corrected gestational age should be 37 weeks.
- Documented HIT defined as a fall in platelet count to less than 100,000/uL or a >=50%
decrease in platelets after the initiation of heparin therapy with no apparent
explanation other than HIT, or
- Require anticoagulation and have a documented history of a positive HIT test in the
absence of current thrombocytopenia (i. e. patients at risk for HIT), or
- In the opinion of the investigator, require alternative anticoagulation due to an
underlying condition, such as AT-III deficiency or heparin resistance.
- Signed (written) informed consent or assent by the patient (if age appropriate) and
the patient's parent or guardian.
Criteria for Exclusion:
- Any condition which, in the investigator's opinion, would contraindicate the use of
Argatroban or would endanger the patient if he/she participated in this trial.
- Unexplained aPTT > 2 times the upper limit of normal at baseline, in the absence of
- International Normalized Ratio (INR) >1. 6 at baseline in the absence of warfarin.
- Known clinical site of bleeding or predisposition to bleeding (e. g., GI bleed,
hematuria, hemorrhagic CVA,retroperitoneal hematoma, diabetic retinopathy, hemorrhagic
pericardial effusion, or hemorrhagic pleural effusion. Patients who have a known
clinical site of bleeding may be enrolled if the investigator deems the risk of
continued thrombosis to outweigh the potential bleeding risk.
- Any patient who has received any investigational medication within 30 days prior to
the first dose of study medication or who is scheduled to receive an investigational
drug other than Argatroban during the course of the study.
- Known hypersensitivity to Argatroban or chemically related compounds.
- Females of childbearing potential who are pregnant (positive serum beta-HCG), breast
feeding, or sexually active and not taking adequate contraceptive precautions (e. g.
IUD or oral contraceptives).
- Any patient receiving a thrombolytic medication (e. g. tPA).
- Any neonate with a corrected gestational age of < or = 44 weeks and bleeding in the
head (Grade I or above) as determined by head ultrasound.
