12. Patients with abnormal coagulation (PT or PTT elevated by 30% above normal limits)
13. Patients on continuous anticoagulation therapy. Patients who were on anticoagulant therapy must complete a washout period of at least 10 days prior to baseline and have confirmed normal coagulation parameters before study inclusion
14. Patients who are not biochemically euthyroid
