Brief Summary:
This is a study in healthy subjects. There are two parts to the study. In the first part of the study each subject will receive a single 10mg dose of each of the four formulations of E550. Based on the results from Part 1, an optimal formulation will be selected for further evaluation in Part 2.

Criteria

Inclusion Criteria:

  • Healthy adult men and women (age ≥ 18 to ≤ 55 years)
  • Body mass index ≥ 18.0 kg/m2 and ≤ 32.0 kg/m2 at the time of screening and baseline of Treatment Period 1

  • Evidence of organ dysfunction or any clinically significant event or illness in the subject's medical history, e.g., history of splenectomy.
  • History of arterial or venous thrombosis, including partial or complete thrombosis (e.g., stroke, transient ischemic attack, myocardial infarction, deep vein thrombosis, or pulmonary embolism). Known family history of hereditary thrombophilic disorders (e.g., Factor V Leiden, antithrombin III deficiency, etc.)
  • Hemoglobin less than the lower limit of normal levels.

In addition, other standard criteria for healthy subjects will be used.
