GLP-1 RECEPTOR AGONIST: LIRAGLUTIDE (SAXENDA ) - OBESITY
GLP-1 MODULATES NUMEROUS FUNCTIONS IN HUMANS GLP-1: Secreted upon the ingestion of food Promotes satiety and reduces appetite Alpha cells: Glucose-dependent postprandial glucagon secretion Beta cells: Enhances glucose-dependent insulin secretion Liver: Glucagon reduces hepatic glucose output Stomach: Helps regulate gastric emptying Data from Flint A, et al.

RESULTS OF THE STUDY
QUESTION ON EMPAREG STUDY The EmpaREg Study demonstrated positive outcomes in all of the following CV outcomes, EXCEPT: RED BLUE GREEN YELLOW Myocardial Infarction; Stroke Heart Failure Hospitalization Cardiovascular Death All Cause Mortality
BIOEQUIVALENCE: HUMALOG U 200 VS 100 SAME DOSE; ½ THE VOLUME
INSULIN GLARGINE U-300 (TOUJEO ) NONBIOEQUIVALENT TO GLARGINE U-100 Noninferior: similar A1c lowering More basal insulin use of Toujeo in both T1 and T2DM Rates of hypoglycemia? For patients controlled on insulin glargine U100, a higher daily dose of TOUJEO will be needed From twice-daily NPH insulin to once-daily TOUJEO, the recommended starting TOUJEO dose is 80% of the total daily NPH dosage
HUMULIN R U-500 KWIKPEN Available in April 2016 Onset of Action = within 30 min Duration of Action = 1 hour Pen: No Dose Conversion compared to Vial
POTENTIAL CANDIDATES FOR U-500 HUMAN REGULAR INSULIN T2DM Patients with obesity/severe insulin resistance Patients requiring >200 units of insulin per day High glucocorticoid therapy Severe systemic infection Gestational diabetes with severe insulin resistance Genetic defects of insulin action Type A insulin resistance syndromes Immune mediated diabetes (anti-insulin receptor antibodies)
INSULIN DEGLUDEC (TRESIBA ) U- 200 AND U-100 FLEXTOUCH
INSULIN DEGLUDEC (TRESIBA ): BEGIN STUDIES Ultra long acting insulin (dosed daily) Onset of Action: 30 90 minutes Its duration of action is up to 42 hours compared to 18 to 26 hours (glargine and insulin detemir) Efficacy: Non inferior to Lantus (glargine) Benefit: Flexibility in day to day dosing time Gough SCL, Harris S, Woo V, et al. Insulin degludec: overview of a novel ultra longacting basal insulin. Diabetes, Obesity and Metabolism. 2013 (15): 301 9
TRESIBA DOSING NO dose conversion between TRESIBA U-100 or U-200 FlexTouch pens The dose window for both FlexTouch pens shows the number of insulin units to be delivered Starting Dose in Insulin Naïve T1DM Patients in insulin naïve patients with type 1 diabetes is ~ 1/3 to ½ of TDD Starting dose in insulin naïve T2DM patients is 10 units once daily
QUESTION ON INSULIN Which of the following insulin(s) is/are bioequivalent (require no dose conversion)? RED BLUE Toujeo (Glargine) U-300 vs. Lantus (Glargine) U-100 Humalog Kwikpen U-200 vs. Humalog Kwikpen U-100 GREEN Humulin R Kwikpen U-500 vs. Humulin R U-100 YELLOW Tresiba (Insulin Degludec) U-200 vs. Tresiba U-100
MINI-CASE PATIENT AB Chief complaint: I want to lose weight HPI: 52-year-old woman with Type 2 DM, HTN Vitals: Weight: 220 lb; Height 5 4 ; BMI 37.8 Labs: HbA1c 8.8% Diet: None Medications Metformin (Glucophage XR) 1,000 mg bid Empagliflozin (Jardiance ) 25 mg daily Liraglutide (Victoza ) 1.8 mg daily HCTZ 25 mg once daily 46
QUESTION ON PATIENT - AB Is this patient, AB a candidate for Saxenda? RED BLUE Saxenda (Liraglutide) is safe Use if you discontinue her Glucophage (Metformin) GREEN Use if you discontinue her Victoza (Liraglutide) YELLOW Use if you discontinue her Jardiance (Empagliflozin)
KEY TAKE AWAY POINTS Clinical trials show 62% and 34% of patients on Saxenda (Liraglutide) 3 mg, decrease weight by 5% and 10% respectively from baseline Empagliflozin demonstrated positive CV outcomes in decreasing HF hospitalizations; CV death and all cause mortality (not MI or Stroke) PK/PD studies must demonstrate bioequivalence in order to maintain dosing in concentrated insulin with their U-100 counterparts Concentrated insulin has the same dose but less volume
QUESTION FOR AUDIENCE On completion of this presentation, RED I learnt at least one important fact today BLUE I am still muddy about one point GREEN I need one area clarified today YELLOW I slept through, so I have no questions
