Background We recently reported improved glycemic control with reduced insulin dose in subjects with type 1 diabetes treated with the sodium glucose co-transporter-2 inhibitor empagliflozin. To further characterize the effects, we analyzed diurnal glycemic patterns by continuous glucose monitoring (CGM). Methods In an 8-week single-arm open-label pilot study of empagliflozin, we compared ambulatory glucose profiles produced from CGM data during 2-week intervals in a placebo run-in baseline period, end-of-treatment, and post-treatment. Change in glycemic exposure was evaluated by area under the median curve according to time of day (AUCTOTAL 12:00am-11:55pm; AUCDAY 7:05am-10:55pm, AUCNIGHT 11:00pm-7:00am), as well as glycemic variability, glycemic stability and time-in-target (≥70 to ≤140mg/dL). Results The 40 patients (26 on insulin pump) were aged 24±5 years and BMI 24.5±3.2 kg/m2. Consistent with the observed HbA1c decrease (8.0±0.9% to 7.6±0.9%, p

OBJECTIVE Adjunctive-to-insulin therapy with sodium-glucose cotransporter 2 (SGLT2) inhibition may improve glycemic control in type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS We evaluated the glycemic efficacy and safety of empagliflozin 25 mg daily in 40 patients treated for 8 weeks in a single-arm open-label proof-of-concept trial (NCT01392560). RESULTS Mean A1C decreased from 8.0 ± 0.9% (64 ± 10 mmol/mol) to 7.6 ± 0.9% (60 ± 10 mmol/mol) (P < 0.0001), fasting glucose from 9.0 ± 4.3 to 7.0 ± 3.2 mmol/L (P = 0.008), symptomatic hypoglycemia ( CONCLUSIONS This proof-of-concept study strongly supports a randomized clinical trial of adjunctive-to-insulin empagliflozin in patients with T1D.

Background— The primary objective of this mechanistic open-label, stratified clinical trial was to determine the effect of 8 weeks’ sodium glucose cotransporter 2 inhibition with empagliflozin 25 mg QD on renal hyperfiltration in subjects with type 1 diabetes mellitus (T1D). Methods and Results— Inulin (glomerular filtration rate; GFR) and paraaminohippurate (effective renal plasma flow) clearances were measured in individuals stratified based on having hyperfiltration (T1D-H, GFR ≥ 135 mL/min/1.73m 2 , n=27) or normal GFR (T1D-N, GFR 90–134 mL/min/1.73m 2 , n=13) at baseline. Renal function and circulating levels of renin-angiotensin-aldosterone system mediators and NO were measured under clamped euglycemic (4–6 mmol/L) and hyperglycemic (9–11 mmol/L) conditions at baseline and end of treatment. During clamped euglycemia, hyperfiltration was attenuated by −33 mL/min/1.73m 2 with empagliflozin in T1D-H, (GFR 172±23–139±25 mL/min/1.73 m 2 , P P P ≤0.04). Conclusions— In conclusion, short-term treatment with the sodium glucose cotransporter 2 inhibitor empagliflozin attenuated renal hyperfiltration in subjects with T1D, likely by affecting tubular-glomerular feedback mechanisms.

Study objective To compare the efficacy and safety of ipratropium bromide reformulated with the chlorofluorocarbon (CFC)-free propellant hydrofluoroalkane (HFA)-134a (ipratropium bromide HFA) to that of the marketed ipratropium bromide inhalation aerosol (containing CFC) in patients with COPD. Design This was a randomized, double-blind, parallel-group, placebo-controlled, multicenter trial. The primary efficacy parameter was acute bronchodilator response. The primary end points were peak change in FEV 1 from baseline and area under the response-time curve. Setting Thirty-one clinical centers in the United States participated in this project. Patients A total of 507 patients with moderate-to-severe COPD were randomized, and 444 patients completed the trial. Interventions Twelve weeks of treatment four times daily with one of the following: ipratropium bromide HFA, 42 μg; ipratropium bromide HFA, 84 μg; HFA placebo; ipratropium bromide inhalation aerosol, 42 μg; or CFC placebo. Measurements and results Patients in all active treatment groups had significant bronchodilator responses as shown by increases in mean FEV 1 from baseline of at least 15%. Bronchodilator response in all active treatment groups was also significantly more than their respective placebo treatments based on FEV 1 , area under the time-response curve from 0 to 6 h, and peak response. FVC results were similar to those seen with FEV 1 . There were no significant differences in adverse events, laboratory findings, or ECG findings among the treatment groups. Conclusions Ipratropium bromide HFA, 42 μg, provided bronchodilation comparable to the marketed ipratropium bromide CFC, 42 μg, over 12 weeks of regular use.

Background Individuals with type 1 diabetes mellitus are at high risk for the development of hypertension, contributing to cardiovascular complications. Hyperglycaemia-mediated neurohormonal activation increases arterial stiffness, and is an important contributing factor for hypertension. Since the sodium glucose cotransport-2 (SGLT2) inhibitor empagliflozin lowers blood pressure and HbA1c in type 1 diabetes mellitus, we hypothesized that this agent would also reduce arterial stiffness and markers of sympathetic nervous system activity. Methods Blood pressure, arterial stiffness, heart rate variability (HRV) and circulating adrenergic mediators were measured during clamped euglycaemia (blood glucose 4–6 mmol/L) and hyperglycaemia (blood glucose 9–11 mmol/L) in 40 normotensive type 1 diabetes mellitus patients. Studies were repeated after 8 weeks of empagliflozin (25 mg once daily). Results In response to empagliflozin during clamped euglycaemia, systolic blood pressure (111 ± 9 to 109 ± 9 mmHg, p = 0.02) and augmentation indices at the radial (-52% ± 16 to -57% ± 17, p = 0.0001), carotid (+1.3 ± 1 7.0 to -5.7 ± 17.0%, p
