Newer Therapies Tell me what you know about: DPP-4i GLP-1 RA SGLT-2i

GLP-1 Receptor Agonists short-acting GLP-1 agonists Exenatide (Byetta ) 5 mcg & 10 mcg Twice-daily dosing Lixisenatide (Lyxumia ) ** 10 mcg & 20 mcg once-daily dosing ** Not FDA approved yet long-acting GLP-1 agonists Liraglutide (Victoza ) 0.6 mg, 1.2 mg, & 1.8 mg Once-daily dosing Exenatide (Bydureon ) 2 mg Once-weekly dosing Albiglutide (Tanzeum ) 30mg & 50mg Once-weekly dosing Dulaglutide (Trulicity ) 0.75 mg & 1.5 mg Once-weekly dosing

GLP-1 Receptor Agonists GLP-1 agonists fix 4 dysfunctional organs in T2DM Glucagon suppression Results in liver glucose production Enhances appropriate insulin and amylin secretion from the pancreas Results in brain satiety Regulates the GI tract to slow gastric emptying time Can be used thru duration provided insulin is present Promising durability Short-acting agonists lowers postprandial glucose Decreases A1c by 0.8% to 1.5% (~20-45 mg/dl; most postprandial) Long acting agonists lowers fasting and postprandial glucose Decreases A1c by 0.8% to 1.8% (~20-50 mg/dl) Most common side effects Weight loss Stomach upset Caution in patients at risk for pancreatitis Cornell S, et al. Postgrad Med. 2012;124(4):84-94.

Comparison of Short-Acting vs Long-Acting GLP-1 Receptor Agonists Parameter Short-Acting GLP-1 RAs Long-Acting GLP-1 RAs HbA1c reduction ~0.5%-1.2% ~0.8%-1.9% Body Weight Reduction ~1-4 kg ~1-4 kg SBP Reduction ~3-4 mm Hg Up to 6 mm Hg Heart Rate Increase Lipids No effect or small increase (0-2 beats/min) Small improvement in some studies 2-4 beats/min Small improvement in some studies HbA1c = glycated hemoglobin; SBP = systolic blood pressure Lund A, et al. Eur J Intern Med. 2014;25(5):407-414.

SGLT-2 Inhibitors Canagliflozin (Invokana ) FDA approved 2013 Dapagliflozin (Farxiga ) FDA approved 2014 Empagliflozin (Jardiance ) FDA approved 2014

SGLT-2 Inhibitors Renal glucose reabsorption in the early proximal tubule of the kidney Body fat - possibly due to water and fat urination (elimination) Lowers fasting glucose Decreases A1C by 0.7% to 1% (~20-30 mg/dl) Most common side effects Weight loss Vaginal and male genital infections Rash UTI Frequent urination Increased thirst GI problems (when combined with metformin) UTI = urinary tract infection. List JF, et al. Diabetes Care. 2009;32:650-657. Wilding JP, et al. Diabetes Care. 2009;32:1656-1662.

Glucose Regulation by the Kidney (180 L/day) (1000 mg/l)=180 g/day Glucose 90% SGLT-2 S1 SGLT-1 S3 10% No Glucose

Mechanistic Differences in Weight Loss SGLT-2 inhibitors Mechanism: glucose loss in urine 1 g glucose = 4 kcal Loss of potentially 200 to 300 kcal/day Maximum weight loss at approximately 6 months Weight loss is, in general, maintained GLP-1 agonists Mechanism: central satiety, other mechanisms? Direct stimulation of several areas of brain Maximum weight loss at approximately 6 months Weight loss is, in general, maintained Berhan A et al. BMS Endocr Disord. 2013;13:58-69. Vilsbøll T et al. BMJ. 2012;344:d7771.

Clinical Pearls Newer Non-Insulin Therapies New therapies have low risk of hypoglycemia, are weight neutral or promote weight loss and have CV benefit SGLT-2i promotes most weight loss Incretin based therapies fix dysfunctional organs: DPP-4i fix liver and pancreas GLP-1 agonists fix liver, pancreas, GI tract and brain DPP-4i, GLP-1 agonists and SGLT-2i are ideal second line (possibly first line) treatment options for many people with T2D. Metformin, GLP-1 agonists and SGLT-2i are in current clinical trials for T1D people with metabolic syndrome (insulin resistance)

Concentrated Insulin

The Basal-Bolus Concept Basal insulin: 50% of daily needs Controls nighttime and between-meal glucose at a nearly constant level Bolus insulin: 50% of daily needs Controls mealtime glucose 10 20% of total daily insulin requirement at each meal Correction dose (sensitivity factor) Correct hyperglycemia reactively

Rationale for true Concentrated Insulin Use When daily insulin requirements are in excess of 200 units/day, the volume of U-100 injected insulin may become an issue Physically too large for a single SC administration Multiple injections are required to deliver a single dose Increased injections may lead to compliance issues and poor glycemic control Discomfort Unpredictable absorption (rate-limiting step in insulin activity)

U-100 Insulin vs U-500 Insulin Humulin R U-500 is highly concentrated and contains 5 times as much insulin in 1 ml as standard U-100 insulin Truly used for patients on high doses of insulin (usually > 200 units daily) Both have onset of action at 30 minutes U-500 insulin exhibits a delayed and lower peak effect relative to U-100 U-500 insulin typically has a longer duration of action compared with U-100 (up to 24 hours following a single dose) Clinical experience has shown that U-500 insulin frequently has time-action characteristics reflecting both prandial and basal activity 40 de la Peña et al. Diabetes Care 2011;34(12):2496-501.

PK and PD profiles for U-500 vs. U-100 Human Insulin 50-unit dose 100-unit dose 50-unit dose 100-unit dose IRI = immunoreactive insulin. de la Peña A, et al. Diabetes Care. 2011;34:2496-2501.

Humulin R U-500 KwikPen Can deliver up to 300 units in a single injection no dose conversion for pen Vials/syringes will need dose conversion dials in 5-unit increments holds 1500 units of insulin in every pen for severely insulin-resistant patients When daily insulin requirements are in excess of 200 units/day

High-Concentration Glargine (U300) U300 insulin glargine offers a smaller depot surface area, leading to a reduced rate of absorption Provides flatter and prolonged pharmacokinetic and pharmacodynamic profiles and more consistency Half-life is ~23 hours Steady state in 4 days Duration of action 36 hours FDA approved February 25, 2015 (Toujeo ) Garber AJ.

Clinical Pearls Concentrated Insulin Watch for over basalization High basal dose with no or little bolus insulin Continually increasing insulin doses does not reduce insulin resistance Humulin R U-500 is useful for patients on very high total daily insulin doses (e.g > 200 TDD/day) Ultra long acting basal insulins (Glargine U-300 and Degludec U-200) provide longer duration of action for better basal coverage with low noctunal hypoglycemia

Importance of Patient Education

BG Lowering Agents and the Best Time to Take Them Agents to be taken before meals AGIs Dopamine agonists Glinides Short-acting GLP-1 agonists Bolus insulin Agents to be taken with or after meals SU Metformin Bolus insulin Agents that can be taken with or without food TZDs DPP-4 inhibitors Long-acting GLP-1 agonists SGLT-2 inhibitors Basal insulin Cornell S, et al.

Six Key Questions to Ask Patients for EVERY Medication They Take 1. What are you taking this medication for? 2. How are you currently taking it? 3. What problems have you noticed since starting this medication? 4. What side effect concerns do you have about your medication? 5. What cost concerns do you have about your medications? 6. What days of the week do you NOT take your medication? How often does this happen? Cornell S et al. Diabetes Trends. 2009; 21(suppl A):3-11.

Take Home Message Diabetes management is constantly evolving Clinicians must stay current with new therapies and trends The longer we wait the more damage is done! Earlier diagnosis and treatment is needed Appropriate drug therapy plus lifestyle modification is needed Monotherapy rarely works, and does so only on a short-term basis Newer and emerging therapies target key organ defects Individualize glycemic goals and therapy One size does NOT fit all Key considerations in therapy Protect β-cell, minimize hypoglycemia, & minimize weight gain
