- Hb ≥ 9 g/dL

- No evidence of significant liver disease:

- Serum bilirubin ≤1.5 x ULN

- INR < 1.3

- ALT and AST ≤ 2 x ULN

- Estimated glomerular filtration rate (eGFR) >30 ml/min/m2

- Serum amylase and lipase ≤ 1.5 x ULN

- Alkaline phosphatase ≤ 2.5 x ULN

- Written informed consent obtained prior to any screening procedures

- Willingness and ability to comply with scheduled visits, treatment plans, laboratory
tests and other study procedures

Exclusion Criteria:

- Patients will be considered ineligible for this study if they meet any of the
following criteria:

coagulation parameters before study inclusion.

- Patients with symptomatic cholelithiasis.

- Patients who are not biochemically euthyroid.

- Patients with known history of hypothyroidism are eligible if they are on adequate
and stable re-placement thyroid hormone therapy for at least 3 months.

- QT-related exclusion criteria:

- QTcF at screening > 470 msec

- Patients with a history of syncope or family history of idiopathic sudden death

- Patients who have sustained or clinically significant cardiac arrhythmias

- Risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia, cardiac
failure, clinically significant/symptomatic bradycardia, or high-grade AV block

- Patients with concomitant disease(s) that could prolong QT such as autonomic
neuropathy (caused by diabetes, or Parkinson's disease), HIV, cirrhosis, uncontrolled
hypothyroidism or cardiac failure

- Family history of long QT syndrome

- Concomitant medications known to prolong the QT interval.

- Potassium < or = to 3.5

- Patients who have any severe and/or uncontrolled medical conditions or other
conditions that could affect their participation in the study such as:

- Patients who have Uncontrolled diabetes as defined by HbA1c>8%* despite adequate
therapy

- Patients with the presence of active or suspected acute or chronic uncontrolled
infection or with a history of immunodeficiency, including a positive HIV test result
(ELISA and Western blot). An HIV test will not be required; however, previous medical
history will be reviewed.

- Non-malignant medical illnesses that are uncontrolled or whose control may be
jeopardized by the treatment with this study treatment.

- Liver disease such as cirrhosis, decompensated liver disease, chronic active
hepatitis or chronic persistent hepatitis.

- Baseline ALT or AST >3x ULN

- Patients with life-threatening autoimmune and ischemic disorders.

- Uncontrolled hypertension

- Patients who have a history of a primary malignancy, with the exception of locally
excised non-melanoma skin cancer and carcinoma in situ of uterine cervix. (Patients
who have had no evidence of disease from primary cancer for 3 or more years are
allowed to participate in the study.)

- History of pancreatitis

- Patients with a known history of hepatitis B or C

- Presence of Hepatitis B surface antigen (HbsAg)

- Presence of Hepatitis C antibody (anti-HCV)

- Patients with a history of, or current, alcohol misuse/abuse within the past 12
months

- Known gallbladder or bile duct disease, acute or chronic pancreatitis

- Patients who have any current or prior medical condition that may interfere with the
conduct of the study or the evaluation of its results in the opinion of the
Investigator or the Sponsor's Medical Monitor

- Patients with a history of non-compliance to medical regimens or who are considered
potentially unreliable or will not be able to complete the entire study
