About
The purpose of this study is to evaluate the change from baseline in hemoglobin A1c (HbA1c) during 12 weeks of treatment with 3 dose levels of LGD-6972 compared to placebo in subjects with Type 2 Diabetes Mellitus (T2DM)
Full description
This will be a 12-week, randomized, double-blind, placebo-controlled, 4-arm, parallel group, multi-center study to evaluate the safety and efficacy of LGD-6972 in subjects with T2DM inadequately controlled on metformin monotherapy (a stable [≥12 weeks], daily dose of ≥1000mg at randomization). Subjects with T2DM will be treated with one of 3 dose levels of LGD-6972 (5 mg, 10 mg, or 15 mg) or placebo once daily (QD) for 12 weeks. Randomization will be stratified by HbAlc ≤8.5% or >8.5% at the Placebo Lead-in Visit.
Qualified subjects who require adjustment or stabilization of their metformin dose will participate in a run-in period of up to 12 additional weeks prior to randomization. Subjects will have the option to participate in an oral glucose tolerance test (OGTT) at baseline and end of treatment for assessment of exploratory endpoints.

Unwilling to comply with study restrictions, including restrictions on strenuous exercise
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
Serum triglyceride level > 400 mg/dL at screening
Liver transaminase levels (AST or ALT) >150% ULN, total bilirubin >2 ULN, or creatine kinase (CK) levels > 3 × ULN at screening
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)
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
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
Arm size in excess of the maximum limit of the largest cuff provided with the study blood pressure monitor
History of malignancy (except adequately treated basal or squamous cell skin cancer or cervical carcinoma in situ) within 5 years prior to screening
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
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
Treated with peroxisome proliferator-activated receptor-gamma agonists (thiazolidinediones [TZDs]), incretin therapy (GLP-1 agonists). or amylin mimetics within 12 weeks prior to screening
Taking any of the following prohibited medications
Treatment with systemic corticosteroids, which must be discontinued at least 4 weeks prior to screening. Note: Inhaled, intraarticular, intranasal and topical corticosteroids are permitted
Currently treated with weight-loss medications. These must be discontinued ≥12 weeks prior to screening

Known hypersensitivity or idiosyncratic reaction to glucagon receptor (GCGR) antagonists or LGD-6972
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 (whichever is longer)
Donated ≥ 450 mL of blood within 56 days of screening or has donated blood products within 30 days of screening
Inability to comply with study procedures or to adhere to study-required restrictions
