Deerfield, IL: Tekeda Pharmaceutical Compay; 2013 FUTURE THERAPIES: SODIUM-GLUCOSE CO-TRANSPORTER-2 (SGLT2) INHIBITORS Renal Handling of Glucose, Non-Diabetic Individual SGLT2 is a low-affinity, high-capacity transporter requiring 1 glucose and 1 sodium molecule. SGLT2 in the kidney plays a critical role in the reabsorption of glucose. It is almost exclusively found in the S1 segment of the proximal renal tubule; accounts for ~ 90% of the renal reabsorption of glucose (180 grams of glucose/day) Breakdown: blocks reabsorption of glucose by the kidney and increases excretion of glucose in urine S1 part of proximal tubule Glucose filtered/day = 180 g Reabsorption Glucose SGLT2 ~90% ~10% S G L T 1 Virtually all the glucose filtered is reabsorbed and glucose does not appear in the urine.

SODIUM-GLUCOSE CO-TRANSPORTER-2 (SGLT2) INHIBITORS First drug in class, dapagliflozin, rejected by FDA in January 2012 Concerned drug raised risk of bladder and breast cancer in 11 phase III clinical trials Second drug, canagliflozin (Invokana) received FDA approval on March 29, 2013 A third SGLT2 inhibitor, ipragliflozin (Astellas Pharma) has been filed for marketing approval in Japan, and a fourth, empagliflozin (Eli Lilly/Boehringer Ingelheim), is in phase 3 trials and has just been filed for approval in the United States. Canagliflozin (Invokana) 26-week, randomized, double-blind, placebo-controlled, phase 3 trial 584 adult subjects with T2DM received canagliflozin 100 or 300 mg or placebo once daily. At week 26, canagliflozin 100 and 300 mg (compared with placebo) significantly reduced A1C from baseline, ( 0.77, 1.03 and 0.14%, respectively; p<0.001 for both). Adverse events The incidence of genital mycotic infections was higher with canagliflozin compared with placebo There incidence of urinary tract infections was higher with canagliflozin compared with placebo The percentage of subjects with documented hypoglycaemia was similar with canagliflozin 100 and 300 mg and placebo (3.6, 3.0 and 2.6%, respectively), with no report of severe hypoglycaemia.

9 CLINICAL INERTIA Defined as failure to intensify treatment of a patient who is not at evidence-based A1c goal Clinical inertia postulated as major barrier to better diabetes care Concern of clinical inertia focusing too closely on sole glucose control; may divert attention from other diabetes quality measures such as blood pressure and LDL control All healthcare providers should be aware of clinical inertia and focus on optimizing all patient outcomes PRINCIPLES OF COMBINATION THERAPY SELECTION Early vs late disease How much A1c lowering needed? Patients with frequent hypoglycemia events? Intolerable side effects Safety profiles Too costly? Insurance coverage? Nonadherence to multiple self-monitoring blood glucose values Ease of use Frequency Injectable vs noninjectable Berlowitz DR, Ash AS, Glickman M, Friedman RH, Pogach L, Nelson AL. Developing a Quality of Measure for Clinical Inertia in Diabetes Care Health Services Research doi: /j x available online at Nathan DM et al. Diabetes Care. 2009; 32: PATIENT CASE # 1 JP is a 62-year-old female with an 2-year history of T2DM. Current A1c = 7.4% Serum creatinine = 1.1 mg/dl; CrCl = 65 ml/min - Body mass index = 30 Current DM therapy includes: Metformin ER 2000 mg daily and Glipizide 20 mg XL daily Question: What changes should be made to DS s T2DM therapy? A) Continue with current therapy and lifestyle changes B) Add sitagliptin (DPP-4) and reduce dose of glipizide C) Add exenatide (GLP-1) and reduce dose of glipizide D) Add basal insulin and discontinue glipizide TACTICS TO IMPROVE PATIENT ADHERENCE Find that teachable moment : Explain how medication would benefit patient Explain goals of diabetes control Explain how patients are in control of their outcomes Identify barriers to adherence: Do patients need to demonstrate injection technique? Are patients concerned about side effects? Is it too expensive? Are they spreading out their supply Encourage, Motivate, Encourage Questions THANK YOU 9
