Subjects must have an HbA1c value of ≥7.0% to ≤10.5% 7. Subjects must have a fasting plasma glucose of ≤260 mg/dL 8. Subjects must have a body mass index (BMI) between 25 kg/m2 and 40 kg/m2, inclusive, and must weigh more than 45 kg Exclusion Criteria: 1.

Unwilling to comply with study restrictions, including restrictions on strenuous exercise 5. Presence of any of the following conditions: renal impairment (defined as history or estimated glomerular filtration rate at screening of \<45 mL/min using the Modification of Diet in Renal Disease equation), diabetic proliferative retinopathy, severely symptomatic diabetic neuropathy requiring treatment, diabetic gastroparesis, active liver disease (other than asymptomatic nonalcoholic fatty liver disease), cirrhosis, symptomatic gall bladder disease, or pancreatitis 6. Serum triglyceride level \> 400 mg/dL at screening 7. Liver transaminase levels (AST or ALT) \>150% ULN, total bilirubin \>2 ULN, or creatine kinase (CK) levels \> 3 × ULN at screening 8. History or evidence of clinically significant cardiovascular, pulmonary, renal, endocrine (other than T2DM), hepatic, neurologic, psychiatric, immunologic, hematologic, gastrointestinal, or metabolic disease or surgical intervention (eg, bariatric surgery) or allergic conditions (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) 9. Myocardial infarction, unstable angina, arterial revascularization, stroke, symptomatic peripheral artery disease, deep vein thrombosis, New York Heart Association Functional Class III or IV heart failure, or transient ischemic attack within 6 months prior to screening 10. History of malignant hypertension or a recent history of uncontrolled high blood pressure or at screening has a seated systolic blood pressure \>160 mmHg and/or diastolic blood pressure \>100 mmHg after at least a 5 minute rest. Blood pressure is determined as the mean of triplicate measurements collected at 2- minute intervals after the subject has been sitting quietly for at least 5 minutes. Therapy for hypertension (beta blockers excluded) that has been stable for at least 8 weeks prior to screening is permitted 11. Arm size in excess of the maximum limit of the largest cuff provided with the study blood pressure monitor 12. History of malignancy (except adequately treated basal or squamous cell skin cancer or cervical carcinoma in situ) within 5 years prior to screening 13. History or evidence of QT prolongation or clinically significant QT prolongation (QTcF \>450 msec) at screening, or other significant ECG findings at screening that may place the subject at increased risk by participating in the study 14. Treatment with any type of insulin (injected or inhaled) for \> 6 consecutive days within 6 months prior to screening or any insulin therapy within 12 weeks prior to screening 15. Treated with peroxisome proliferator-activated receptor-gamma agonists (thiazolidinediones \[TZDs\]), incretin therapy (GLP-1 agonists). or amylin mimetics within 12 weeks prior to screening 16. Taking any of the following prohibited medications * Antidepressants, antipsychotics, anti-epileptics, hormone replacement therapies (estrogen, progestin), testosterone therapies, and thyroid replacement medications that are not at a stable dose for at least 12 weeks prior to screening * Lipid-modifying medications and anti-hypertensive medications that have not been at a stable dose for at least 8 weeks prior to the Screening Visit (excluding bile acid sequestrants, ezetimibe, and beta blockers, which are prohibited * Over-the-counter herbal medications and supplement (aside from once daily multivitamins) 17. Treatment with systemic corticosteroids, which must be discontinued at least 4 weeks prior to screening. Note: Inhaled, intraarticular, intranasal and topical corticosteroids are permitted 18.

History or evidence of intravenous illicit drug use, active hepatitis B virus (HBV), hepatitis C virus (HCV), and/or human immunodeficiency virus (HIV) infection 20. Known hypersensitivity or idiosyncratic reaction to glucagon receptor (GCGR) antagonists or LGD-6972 21. Participation in another interventional clinical trial within 30 days prior to dosing or treatment with an investigational product with 14 days or 5 half-lives of the Screening Visit (whiche…
