Inclusion Criteria:

• Males or females aged from 18 to 65 years (inclusive).

• Hyperthyroidism, including abnormal screening lab values with FT4 > ULN and TSH < LLN.
• Fasting triglycerides > 499 mg/dL(5.64 mmol/L) ,if elevated at Screening, but not on a subsequent re-check, patient will be eligible. Otherwise, patients can't be enrolled.
• LDL-cholesterol ≥ 190 mg/dL(4.92 mmol/L).
• HbA1c greater than 9.0%
• Fasting glucose > 270 mg/dL(11.0 mmol/L) ,if elevated at Screening, but not on a subsequent re-check, patient will be eligible. Otherwise, patients can't be enrolled.
• Clinically significant abnormal hepatic (e.g., AST or ALT > 2.5x ULN, or total bilirubin > 1.5x ULN) or renal function lab tests (e.g., creatinine > 1.25x ULN) suggestive of hepatic or renal impairment.
