Clinical Trial Summary

Primary Objectives: To assess in overweight to obese T2DM patients: - The glucagon receptor occupancy of SAR425899 at two dose levels in the human liver with positron-emission tomography (PET) imaging using [68Ga]Ga-DO3A-VS-Cys40-Tuna-2 as a tracer compound. - The GLP-1 receptor occupancy of SAR425899 at two dose levels in the human pancreas with PET imaging using [68Ga]Ga-DO3A-VS-Cys40-Exendin-4 as a tracer compound. - Pharmacodynamic effects on fasting plasma glucose and biomarkers of lipid metabolism. - Pharmacokinetic parameters for SAR425899 after repeated subcutaneous (SC) doses in plasma. - Safety and tolerability of SAR425899.

Description:

Study duration is approximately 7 weeks with a 20 days treatment period.

• Presence or history of drug hypersensitivity (including known allergic reactions associated with glucagon like peptide-1 (GLP-1) agonist treatment [exenatide, liraglutide, lixisenatide]), or allergic disease diagnosed and treated by a physician.
• Any intake of menopausal hormone replacement therapy, systemic corticosteroids, growth hormones, weight-loss drugs, antihyperlipidemic treatment, antihyperglycemic treatment [e.g., GLP-1 agonists, insulin, thiazolidinediones, dipeptidylpeptidase (DPP-IV) inhibitors, sodium/glucose cotransporter-2 (SGLT-2) inhibitors etc.]) during the treatment period and within 21 days before first dosing or within 5 times the elimination half-life or pharmacodynamic half-life of the medication (if known), with the exception of metformin, sulphonylureas (SU), standard antihypertensive treatment, statins and acetyl salicylic acid.
• Any condition possibly affecting gastric emptying or absorption from gastro-intestinal tract (e.g., gastric surgery, gastrectomy, bariatric surgery, malabsorption syndromes, gastroparesis, abdominal surgery other than appendectomy, hysterectomy, cholecystectomy and herniaplasty).
• Surgically treated obesity, bariatric surgery.
• Severe dyslipidemia with fasting triglycerides >450 mg/dL at screening.
• Severe hypoglycemia resulting in seizure/unconsciousness/coma or hospitalization for diabetic ketoacidosis in the last 3 months before screening.
• Persistent hyperglycemia not adequately controlled by metformin, SUs and/or diet/exercise.
• Diagnosed diabetic neuropathy, retinopathy, nephropathy or renal impairment (GFR <60 mL/min; estimate after Cockcroft-Gault) at screening.

• History of pancreatitis or pancreatectomy.
• Amylase and/or lipase > 2 upper limit of normal (ULN) at screening.
• Personal history or family history of medullary thyroid cancer or a genetic condition that predisposes to medullary thyroid cancer.
• Elevated basal calcitonin (=20 pg/mL / 5.9 pmol/L) at screening.
• Known past or present diseases or disorders of any target organ (liver, pancreas, spleen).
• Medical positron emitting tomography (PET), single photon emission computer tomography (SPECT), abdominal or thoracic computer tomography (CT) examination during the previous 12 months' time period.
