Introduction: Therapeutic inertia is a major contributor to people with diabetes not achieving glycemic goals. We assessed for patients with T2D the impact of using the FreeStyle Libre system (FSL) vs. blood glucose monitoring (BGM) on treatment intensification. Method: We carried out a matched retrospective cohort study using secondary private payer claims data including >30 million diabetes drug and device claims filled by over 850,000 patients with T2D >18 in Canada over 24 months. Each month, patients were classified by level of therapy progression: 1. No diabetes drug therapy; 2. Mono Oral Antihyperglycemic Agents (OHAs) ; 3. Dual OHAs; 4. Triple OHAs; 5. Quad or more OHAs; 6. Injectable GLP1-RA (±concomitant OHAs) ; 7. Basal insulin (±concomitant OHAs) ; 8. MDI insulin (±concomitant OHAs) . Results: A total of 373,871 patients met the inclusion criteria. Across all treatment cohorts, the FSL treatment groups were found to have a statistically higher probability of treatment intensification relative to BGM: Conclusion: Reimbursement of FSL for patients with T2D in Canada is associated with decreased time lag for glucose lowering therapy compared to those using BGM alone. These findings suggest that FSL data impact clinicians to facilitate earlier and more intensive therapy modifications and thus reduce treatment inertia.

Most prediction models for diabetes-related iatrogenic severe hypoglycemia (SH) have derived from trial/administrative records subject to poor generalizability, ascertainment bias, and incomplete data capture. Redressing this gap, iNPHORM leveraged the clinical and methodological advantages of prospective self-report to develop and internally validate a 1-year SH prediction model for use in real-world clinical contexts. Adults (18-90 years old) with insulin- and/or secretagogue-treated type 1 or 2 diabetes (T1D, T2D) were recruited from a US-wide probability-based internet panel and followed for one year. Monthly emailed questionnaires assessed SH incidence and related factors. To model recurrent 1-year SH (daytime + nocturnal) , Andersen-Gill Cox proportional hazards regression was performed on participants completing ≥1 follow-up. Missing data were multiply imputed with chained equations. Machine learning penalized regression with lasso was used to select clinically plausible predictors. A total of 986 (T1D: 17%) participants were analyzed (retention rate: 86.2%) . The mean age was 51 (SD: 14.3) years, 49.6% were male, and the median duration of T1D/T2D was 12 (IQR: 14) years. Among T2D participants, 38% were on insulin (without secretagogues) , 38% on secretagogues (without insulin) , and 24% on insulin plus secretagogues. Across follow-up, 35.1% (95% CI: 32.2-38.1%) reported ≥1 SH, and the annual rate was 4.97 (95% CI: 4.13-5.99) . Combination insulin-secretagogue therapy; use of an insulin pump and continuous glucose monitoring; decreased age; increased previous SH requiring healthcare utilization; chronic kidney disease; and food insecurity predicted 1-year SH risk. The optimism adjusted c-statistic was 0.75. iNPHORM is the first long-term, prospective study on SH prediction in the general US population with T1D and T2D. Our 7-variable model can be used to identify patients at high-risk of SH, leading to more valid, cost-effective prevention strategies in the real world.

The PIONEER 8 (NCT03021187) trial demonstrated significant glucose-lowering efficacy of oral semaglutide vs. placebo (pbo) in patients (pts) with T2D inadequately controlled with insulin. Additionally, those assigned to oral semaglutide (7 or 14 mg daily) had a lower total daily insulin dose at end of treatment (week 52) relative to baseline, vs. those treated with pbo, suggesting an insulin-sparing effect. This post-hoc analysis of PIONEER 8 aimed to characterize the transition of adding a GLP-1RA to insulin therapy and to quantify reductions in total insulin dose seen with the addition of oral semaglutide. A 20% reduction in total daily insulin dose was recommended at randomization up to week 8. Total daily insulin was not to exceed pre-randomization dose between weeks 8 and 26 but was freely adjustable at the investigator’s discretion from week 26 to 52. For all doses of oral semaglutide, a greater proportion of pts were able to maintain a greater level of insulin dose reduction vs. pbo at week 26 (Figure) . Greater proportions of pts on oral semaglutide 3, 7, and 14 mg achieved ≥20% reductions in insulin vs. those in the pbo group at both weeks 26 and 52 (Treatment policy estimand; 27.5%, 28.9%, 31.2% vs. 12.4% and 19.5%, 25.0%, 32.0% vs 5.7%, respectively; P Disclosure V.R.Aroda: Consultant; Applied Therapeutics, Fractyl Health, Inc., Novo Nordisk, Pfizer Inc., Sanofi, Other Relationship; Janssen Pharmaceuticals, Inc., Merck & Co., Inc., Research Support; Applied Therapeutics, Fractyl Health, Inc., Novo Nordisk, Sanofi.

Background: This study describes the impact of the pandemic on the management of people with type 2 diabetes (PwT2D) in a primary care network with existing virtual care capabilities in Ontario, Canada. Methods: Using de-identified primary care electronic medical records, PwT2D who had at least one healthcare touchpoint between March 1, 2018 and February 28, 2021 were analyzed by time period (baseline: 2018-19, pre-COVID-19: 2019-20, COVID-19: 2020-21) . The primary outcome measures include the number of people with at least one visit, number of people with vital measurements or lab tests, and the vital or lab results. Results: The three time periods had a similar average age and gender distribution (Table 1) . Compared to the pre-COVID-period, fewer people had any healthcare touchpoint (17% reduction) . In-person visits were reduced while more people had virtual visits. Fewer people had test results recorded during the COVID-vs. two pre-COVID-time periods, however, average results were similar across all three time periods. Conclusion: Our study described the immediate impact of the COVID-pandemic on patterns of primary care for PwT2D. While the total number people getting tests remains below pre-pandemic levels, of those who sought care, the mean A1c, LDL-c and eGFR were comparable across the three time periods.

Background: COVID-public health measures may have impacted diabetes care through delayed care and reduced medication access. This study describes antihyperglycemic medication prescription patterns among adults with type 2 diabetes (T2D) before and during the COVID-pandemic in Canada. Methods: Using IQVIA’s longitudinal pharmacy based prescription data, antihyperglycemic prescriptions from March 1, 2018 to February 28, 2021 were analyzed among adults who had ≥1 prescription for a non-insulin antihyperglycemic drug. The number of people who: 1) had antihyperglycemic prescriptions,2) were newly started on antihyperglycemic drugs, and3) were newly diagnosed with T2D (inferred from prescriptions) were reported. Results: The number of people who had ≥1 antihyperglycemic prescription was comparable in the year of the COVID-pandemic (March 2020 to February 2021) and the year prior (March 20to February 2020) . The number of people who newly initiated a GLP-1RA, SGLT2i or second-generation basal insulin analogue decreased for the first few months of the pandemic (April to September 2020) with recovery thereafter. The number of people who were newly diagnosed with T2D decreased by 7% in the COVID-year. Conclusion: Fewer people initiated newer antihyperglycemic medications and fewer people were newly diagnosed with T2D in the first few months for the pandemic which may reflect reduced health care access.

Introduction: Hypoglycemia after BI initiation can negatively impact patient adherence to titration and glycemic target achievement. We report on 2 surveys to better understand patient and physician perspectives/experiences of hypoglycemia during BI titration. Methods: Adults with T2D and ≥2 claims (≥30 days apart in last 12 months) in the Optum Research Database who initiated BI (February-April 2021) , and physicians who treated ≥30 patients with T2D, ≥1 initiating BI (October 2020-March 2021) , completed a mailed survey. Results: Responders were 416 patients (51% male, 71% white, mean age 70 years, 72% >years T2D duration) and 386 physicians (45% general practice) . Most physicians reported discussing hypoglycemia signs/symptoms (93%) and how to titrate BI in response to blood glucose (BG) levels (81%) with patients. Among patients who experienced hypoglycemia (49%; Table) , 57% felt very/extremely confident titrating BI during hypoglycemia. Only 35% met fasting BG (FBG) targets. Diabetes Treatment Satisfaction Questionnaire hypoglycemia score (1.34/6) suggests patients felt hypoglycemia was infrequent. Conclusion: While physicians educate patients on hypoglycemia awareness and BI titration, nearly half of patients surveyed experienced hypoglycemia during titration, and only a third met FBG targets, suggesting new strategies and tools are needed for effective BI titration.

Iatrogenic non-severe hypoglycemia (NSH) is a common and known precursor of severe hypoglycemia. Still, virtually no valid risk estimators exist to predict daytime and nocturnal NSH (NSDH, NSNH) in the general US population with diabetes. To redress this gap, we analyzed primary, self-reported data from the 1-year, prospective iNPHORM study. Adults (18-90 years old) with insulin- and/or secretagogue-treated type 1 or 2 diabetes (T1D, T2D) were recruited from a US-wide probability-based internet panel. Twelve monthly emailed questionnaires assessed NSH risk. Prognostic models were built for recurrent 30-day NSDH and NSNH using negative binomial and machine learning penalized regression with lasso. Missing data were multiply imputed with chained equations. N=986 were analyzed (T1D: 17%; age: 51 [SD: 14.3] years; male: 49.6%; T1D/T2D duration: 12 [IQR: 14] years; retention rate: 86.2%) . Among T2D respondents, 38% were on insulin alone, 38% secretagogues alone, and 24% insulin plus secretagogues. Follow-up incidence proportions and 30-day rates of NSDH and NSNH were 79.6% (95% CI: 77.0-82.0%) and 1.70 (95% CI: 1.59-1.82) , and 53.7% (95% CI: 50.5-56.7%) and 0.69 (95% CI: 0.64-0.75) , respectively. Risks of 30-day NSDH and NSNH increased with insulin+secretagogue therapy; A1C≤7%; insulin pump, continuous glucose monitoring, beta blockers, and antibiotics use; decreased number of medications; T1D and diabetes education; increased past severe hypoglycemia requiring healthcare; chronic kidney disease; depression; food insecurity; lack of insurance; younger age; female sex; and White race; risks decreased with A1C≥7.1%, cognitive impairment, hypoglycemia unawareness, and insurance. As well, higher income predicted NSNH risk. The optimism adjusted c-statistics for NSDH and NSNH risks were 0.78 and 0.77, respectively. As the first US study to prospectively estimate real-world NSDH and NSNH risk, iNPHORM provides important insight into individual-level event detection and prevention.

Patients' satisfaction is a key determinant of treatment adherence and persistence, for optimal management of T2D. ATOS, a 12-month prospective observational study conducted in Asia, Middle East, North Africa, Latin America, and Eastern Europe, showed that initiation of Gla-300 in insulin-naïve people with T2D resulted in improved glycemic control with low rates of hypoglycemia. This analysis evaluated changes in treatment satisfaction and health status among participants. Data was collected using PRO questionnaires - Diabetes Treatment Satisfaction Questionnaire status (DTSQs) and change versions (DTSQc) , EuroQoL 5-dimension scale version 3L (EQ-5D-3L) at baseline, Month 3, 6 and 12. Overall, 3931 participants completed the questionnaires. Mean ±SD age was 57.5 ±10.6 years, duration of diabetes was 10.1 ±6.2 years and baseline HbA1c was 9.3 ±1.0 %. Treatment satisfaction improved over time (DTSQs score of 21.7 at baseline to 29.8 and 31.3 at Month 6 and 12, respectively) and perceived frequency of hyperglycemia decreased over 12 months. DTSQc results were aligned with DTSQs. EQ-5D-3L results showed that proportion of people with better health status increased over time (Table) . Results showed that initiating Gla-300 in insulin-naïve people with T2D across multiple geographic regions improved treatment satisfaction and health status. Disclosure N.Khan: None.

Background: Individual and societal determinants can affect the need and propensity for healthcare utilization (HCU) following diabetes-related severe hypoglycemia (SH). This is the first US study to explore the real-world risk factors of HCU- versus non HCU-based SH. Methods: Data were collected online from a generalized cohort of Americans (≥18 years old) with type 1 or type 2 diabetes (T1D, T2D) on insulin and/or secretagogues. Multivariable logistic regression using backward selection was performed to identify the socio-demographic/clinical risk factors of past-year HCU- versus non HCU-based SH (daytime/nocturnal SH resulting in hospital or paramedical services). Results: Results are based on 642 (T1D: 22.7%; female: 46.3%) of 1694 baseline respondents who experienced ≥1 SH events (past year). People with T1D were 40.9 (SD:12.5) years old, while those with T2D were 45.4 (SD: 13.3) years old. Among T2D respondents, 42.5% were on insulin and secretagogues, 31.1% were on insulin alone, and 26.4% on secretagogues alone. Almost half (44.6%) of participants (T1D: 29.9%; T2D: 49.0%) reported ≥1 HCU-based SH events (past year). In the final backward logistic model, the odds of past-year HCU-based SH decreased significantly with female sex, increasing age, decreasing income, and suburban or rural (versus urban) living. Diabetes type did not have an independent effect. However, for individuals on combination insulin-secretagogue therapy, the adjusted odds of HCU-based SH were 2- and 3-times that of those on insulin alone and secretagogues alone, respectively. High A1C (versus Conclusion: Our study reveals several factors that can promote or reduce the odds of HCU-based SH. Therapeutic optimizations to mitigate non-essential HCU should prioritize patients on combination insulin-secretagogue therapy and those with poor glycemic control. Disclosure A.

Background: Diabetes remission due to non-surgical approaches has not been well studied. We investigated induction of diabetes remission following a short-term treatment with insulin glargine, lixisenatide and metformin and changes in exercise and dietary behaviours. Methods: We randomized 160 individuals with type 2 diabetes to (i) 12-week intensive treatment with insulin glargine, lixisenatide, metformin and lifestyle approaches or (ii) standard glycemic management. At 12 weeks, diabetes medications were stopped in patients with HbA1C Results: The intervention significantly reduced the hazard of diabetes relapse (HR 0.57, 95% CI 0.40-0.81; p=0.002). The proportion of participants with diabetes remission was significantly higher in the intervention group compared to the control group at 24 weeks (38% vs. 20%; relative risk RR 1.92 (1.14-3.24)) and at 36 weeks (32% vs. 17%; RR 1.83 (1.03-3.26)), but not at 48 and 64 weeks (RR 1.88 (1.00-3.53) and 2.05 (0.98-4.29), respectively). Conclusion: Short-term intensive treatment targeting normoglycemia and weight loss with insulin glargine, lixisenatide, metformin and lifestyle changes can induce sustained remission of type 2 diabetes.

The combination of basal insulin with a GLP-1 RA may be helpful for people with T2DM to achieve and maintain HbA1c targets compared with each used individually. This randomized, 26-week, multicenter Phase 3 study (NCT03767543) in people with T2DM included participants with HbA1c ≥7.5% and ≤10.5%, and on basal insulin for ≥6 months (dose of ≤40 units/day). In addition to background oral glucose lowering medications, all participants received once-daily iGlarLixi, a fixed-ratio combination given within 1 hour prior to their first meal of the day, and were randomized 1:1 with instructions to titrate daily using a 1 unit per day algorithm or the traditional once-weekly titration (2 or 4 units per week) with target FPG of 4.4 to 5.6 mmol/L (79.2 to 100.8 mg/dL). Daily titration of iGlarLixi was superior to a weekly titration for the primary endpoint of change from baseline in HbA1c at week 26. The proportion of participants experiencing ≥1 gastrointestinal event(s) (27.9% daily vs. 27.8% weekly titration) and incidence of hypoglycemic events (84% daily vs. 81% weekly titration) were similar between the two arms. In this randomized trial, a daily titration algorithm for iGlarLixi was demonstrated as a safe alternative to the traditional weekly titration, while allowing patients to reach their maintenance dose earlier.

An exploratory subgroup analysis of the 52-week, double-blind PIONEER 8 trial (NCT03021187) evaluated the effect of background insulin regimen (basal, premixed, or basal-bolus) with or without metformin on the efficacy and safety of oral semaglutide (sema). Patients (pts) (N=731) with type 2 diabetes and treated with insulin were randomized to once-daily oral sema (3, 7, or 14 mg) or placebo (pbo). Endpoints included change from baseline in HbA1c, body weight (BW), and total daily insulin dose at week 52. Baseline age and HbA1c were similar across insulin regimen subgroups whereas BW was greater and diabetes duration was longer in pts on basal-bolus vs. basal and premix subgroups. There were greater dose-dependent HbA1c and BW reductions with oral sema vs. pbo; these were generally similar across all insulin subgroups (Table). Total daily insulin dose at week 52 was decreased for pts on basal (oral sema 7 and 14 mg), premix (oral sema 14 mg), and basal-bolus (oral sema 3, 7, and 14 mg), mainly driven by the bolus component for pts on basal-bolus (Table). Most hypoglycemic episodes were in pts on basal-bolus insulin. Fewer pts had hypoglycemia with oral sema vs. pbo except in the basal-bolus subgroup (Table). In conclusion, oral sema reduced HbA1c and BW in a dose-dependent manner, and reduced insulin dose regardless of background insulin regimen, with a safety profile similar to other glucagon-like peptide-1 receptor agonists.

BI analogs can help optimize glycemic control in people with T2D, but the patients’ satisfaction is key for acceptance and treatment adherence. ACHIEVE, REACH, and REGAIN were open-label real-world studies comparing Gla-300 with standard of care BI (ACHIEVE: insulin glargine 100 U/mL [Gla-100] or insulin detemir [IDet]; REACH and REGAIN: Gla-100, IDet, insulin degludec [IDeg] or neutral protamine Hagedorn). EDITION 1-3 and BRIGHT were open-label RCTs comparing Gla-300 with Gla-100 and IDeg, respectively. All studies were in people with uncontrolled T2D and used the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs; Table). In RCTs and real-world studies, initiating BI in insulin-naïve participants was associated with improved treatment satisfaction after 6 months (ACHIEVE, 12 months) and a reduction in the perceived frequency of hyperglycemia. Perceived hypoglycemia increased slightly from low baseline values. Similar findings were found in patients switching BI, with improved patient satisfaction and reduced perceived frequency of hyperglycemia after 6 months of treatment, and no change in perceived hypoglycemia. Initiating or switching BI in people with uncontrolled T2D can improve patient satisfaction, irrespective of baseline diabetes treatment. Disclosure S.B.

Minimizing hypoglycemia is a key clinical goal for healthcare providers (HCPs) in the care of patients with T1DM and T2DM as the associated morbidity and mortality of hypoglycemia is well understood. Yet, there is a paucity of literature regarding the impact of reported hypoglycemia on HCPs. Using qualitative data from the InHypo-DM Study, Canada’s largest mixed methods study of hypoglycemia to date, we explored the emotional impact of patients’ hypoglycemia on HCPs. Our research team conducted semi-structured interviews lasting 30-45 minutes. Interviews were transcribed verbatim. An iterative and interpretative process was used during both individual and team analysis to identify the main themes. A purposive sample of twenty HCPs was interviewed including endocrinologists (4), family physicians (4), nurse practitioners (3), and diabetes educators (9). Three themes emerged in the analysis: (1) a sense of professional responsibility with the subsequent feeling that the HCP must have failed or inadequately fulfilled their professional duties; (2) a mix of personal emotions including sadness, “feeling bad,” guilt and distress; and (3) the desire to act on these emotions through a “call to action” expressed as a strong desire to identify potential causes of patients’ hypoglycemia and ways in which to help prevent future events. This qualitative study highlights the emotional impact on HCPs as they care for patients at risk of hypoglycemia. While it may have been expected that HCPs have a strong sense of professional responsibility, it was unexpected to discover that these responses often became personal emotions. Clinical strategies that support HCPs in their efforts to optimize hypoglycemia detection and prevention should be promoted. Such strategies could help facilitate not only reductions in hypoglycemia among patients, but also lessen the emotional burden experienced by diabetes care providers over the span of their careers.

Titration following initiation of BI tends to occur in the first 8-12 weeks. At this time, patients may be at risk of experiencing hypoglycemia, which itself may present a barrier to optimal glycemic control. BRIGHT was the first randomized controlled trial comparing efficacy and safety of two second-generation BI analogs in insulin-naïve patients with T2DM, and showed less hypoglycemia with insulin glargine 300 U/mL (Gla-300) vs. insulin degludec 100 U/mL (IDeg) in the initial 12-week titration period. We investigated patient characteristics and clinical outcomes (including HbA1c change, and hypoglycemia incidence during weeks 13-24) by the occurrence of early confirmed (≤70 mg/dL) hypoglycemia (in the titration period) using descriptive statistics. Participants experiencing hypoglycemia within the first 12 weeks tended to be older, had lower BMI, more impaired renal function, longer duration of diabetes, and were more likely to be using SUs at baseline (Table). Overall, hypoglycemia incidence during weeks 13-24 was lower in the group that did not experience hypoglycemia within the first 12 weeks. HbA1c reductions at week 12 were greater in those with hypoglycemia in the titration period. These findings suggest that patients experiencing early hypoglycemia with second-generation BI analogs have increased hypoglycemia risk in later stages of therapy. Disclosure S.B.

Long-acting insulin analogs have the potential to optimize glycemic control in type 2 diabetes, but the patients’ perspective is key for acceptance and treatment adherence. BRIGHT investigated safety and efficacy of initiating the second-generation basal insulin analogs insulin glargine 300 U/mL (Gla-300) vs. insulin degludec 100 U/mL (IDeg-100) in insulin-naïve people with T2DM. We report data on patient satisfaction from the BRIGHT trial and the EDITION 3 trial (Gla-300 vs. insulin glargine 100 U/mL [Gla-100]). BRIGHT and EDITION 3 were both multicenter, open-label, randomized, parallel-group trials with primary endpoint at 6 months. Randomized participants titrated to a fasting SMPG of 80-100 mg/dL (once-daily evening dosing). The Diabetes Treatment Satisfaction Questionnaire (DTSQ) was completed at baseline and 6 months. Overall, initiating basal insulin analogs was associated with improved treatment satisfaction (Table). There was a numerically greater decrease in perceived hyperglycemia frequency for Gla-300 and IDeg-100 vs. Gla-100 and only a very small increase in the perceived hypoglycemia frequency for all insulins. Similar treatment satisfaction improvement for all insulins was observed. In randomized controlled trials, initiating basal insulin analogs is associated with improved treatment satisfaction, with little increase in perceived hypoglycemia frequency. Disclosure L.

Impaired awareness of hypoglycemia (IAH) has been linked to an increased rate of severe hypoglycemia (SH) in T1DM. Yet, few investigations have focused on quantifying this relationship in the context of T2DM, particularly from a pragmatic epidemiological lens. This study leverages the value of self-reported SH data to explore the real-world, population-based effect of IAH severity on SH rates in T2DM. A validated questionnaire (InHypo-DMPQ) was administered online to a nationally representative panel comprising Canadians (≥18 years) with T2DM using insulin and/or secretagogues. Data were collected on respondents’ socio-demographic/clinical traits; self-reported incidence of SH (in the past year); and IAH severity, trisected by no, moderate, and severe impairment. Multivariable negative binomial regression (NBR) analysis was used to isolate the effect of IAH on SH. A directed acyclic graph was devised to identify the minimally sufficient adjustment set. Of the 452 complete respondents (mean age: 53.2 (SD: 14.7) years; male: 56%), 6% were classified with severe IAH, 67% with moderate IAH, and 27% with no IAH. Those with severe IAH had the highest crude annual SH rate (5.89 events/person-year, 95% CI: 5.01-6.88), which over doubled and tripled the SH rate in people with moderate IAH (p This real-world, population-based study provides timely insight into the high prevalence of moderate and severe IAH in people with T2DM using insulin and/or secretagogues. The marked impact of IAH on increased SH rates underscores a pressing need for the clinical prioritization of IAH assessment and management in T2DM. Disclosure A. Ratzki-Leewing: None. S.B.

Patients (pts) with T2D uncontrolled on insulin ± metformin were randomized to oral semaglutide (sema) 3 mg (N=184), 7 mg (N=182) or 14 mg (N=181), or placebo (pbo; N=184) in a 52-week (week) double-blind trial (NCT03021187). Total daily insulin dose was reduced by an optional 20% and capped at baseline (BL) level for week 0-26 and freely adjustable for week 26-52. Endpoints were change from BL to week 26 in HbA1c (primary) and body weight (BW; confirmatory secondary). Two scientific questions were addressed by defining two estimands: a treatment policy estimand (regardless of trial product discontinuation or rescue medication use), and a trial product estimand (on trial product without rescue medication use) in all randomized pts. Oral sema was superior to pbo in reducing HbA1c and BW at week 26 (treatment policy estimand). Significantly greater, dose-dependent HbA1c and BW reductions vs. pbo were achieved at week 26 and 52 (both estimands; Table). Total daily insulin dose was significantly reduced from BL with oral sema vs. pbo at week 26 (except 3 mg) and 52. The rate of hypoglycemia was not significantly different vs. pbo (Table). Most frequent AE with oral sema was nausea (11.4-23.2% of pts vs. 7.1% with pbo) and 7.1-13.3% of pts prematurely discontinued due to AEs (vs. 2.7% with pbo). As add-on to insulin ± metformin, oral sema had superior HbA1c and BW reductions vs. pbo at week 26. It also reduced insulin use by week 52 and was well tolerated without significantly increasing hypoglycemia rate. Disclosure B.

While sulfonylureas (SUs) are known to induce hypoglycemia, their low cost and ease-of-use has made them a mainstay therapy for T2DM. Second-generation SUs (SGSUs), compared to first-generation SUs (FGSUs), have been successful at reducing these events. Pragmatic evidence substantiating this association remains limited; this study leverages data from the population-based InHypo-DM study to describe the real-world patterns of SU use and impact on hypoglycemia incidence in Canada. A validated questionnaire (InHypo-DMPQ) was administered online to a nationwide panel consisting of adults with SU-treated T2DM. Questions related to respondents’ past hypoglycemia events, as well as socio-demographic and clinical traits. Negative binomial regression (NBR) was used to test the effect of SU type (FGSUs (chlorpropamide/tolbutamide) vs. SGSUs (glyburide/gliclazide/glimepiride)) on the annual rate of any hypoglycemia. A directed acyclic graph was constructed to identify the adjustment set. Of the 255 adults with SU-treated T2DM (56% male, mean age: 53.1 (SD: 14.4) years), 10.6% were on FGSUs (chlorpropamide: 7.5%, tolbutamide: 3.1%) and 89.5% on SGSUs (glyburide: 27.5%, gliclazide: 54.9%, glimepiride: 7.1%). Annualized crude event frequencies revealed that those on FGSUs, vs. SGSUs, were 1.57 times as likely to have ≥1 event; this group also experienced an average of 2.70 more events/person-year. Based on the NBR, FGSUs vs. SGSUs was associated with a 2.76 (95% CI: 1.07-7.11, p=0.035) factor increase in the rate of hypoglycemia, adjusting for drug coverage, T2DM duration, income, and clinician type. These results confirm that FGSUs induce a dangerous, real-world risk for hypoglycemia. It exposes a worrying trend for the continued use of outdated SUs for T2DM, despite the availability of safer alternatives in Canada. Our study serves as a pressing call-to-action to ensure that clinicians provide the safest and most effective therapeutic management for patients with T2DM. Disclosure N.H. Au: None. A.

Many patients fail to report severe hypoglycemia (SH) events to their healthcare provider (HCP). This limits the ability of HCPs to adjust treatment regimens and optimize glycemia. This study aimed to explore the independent association between patients’ disclosure of SH events to their HCP and self-reported rates of SH. Data were obtained from the InHypo-DM population-based study, Canada’s largest hypoglycemia-specific survey. To indicate SH disclosure, patients at risk for hypoglycemia rated how often they reported their SH events (using ADA definitions) to their HCP on a scale from Never to Always. Univariable analyses identified significant clinical or demographic confounders (p≤0.2). Based on the distribution of SH events, zero-inflated negative binomial (ZINB) regression was used to test the relationship between hypoglycemia disclosure and the retrospective incidence of SH events. A total of 552 people with T1DM (17%) or T2DM (83%) completed the InHypo-DM survey. Forty percent of respondents reported at least one or more SH events. The overall incidence rate of SH was 2.45 events/person-year. Thirty-four percent of respondents indicated that they always report SH events. Results of the ZINB model showed that the odds of experiencing any event was not significantly associated with disclosure behaviour (p=0.86). However, the rate of repeated events was almost double (IRR=1.9, 95% CI: 1.2 to 3.0, p=0.004) among individuals who under-reported their SH as compared to those who did not. These results persisted after adjusting for age, medication type, income, most recent HbA1c, and presence of comorbidities. This population-based study revealed a nearly two-fold higher rate of SH among those who under-report to their HCP. Thus, HCPs should be aware that patient reporting may not be a true reflection of SH events and make efforts to elicit accurate information regarding SH events from their patients, especially for those at risk for repeated SH.

Insight into the self-reported frequency of third-party assisted severe hypoglycemia (SH) is critical for the therapeutic optimization of type 2 diabetes (T2D). This study presents real-world epidemiological evidence on the self-reported incidence and related risk indicators of SH. A validated questionnaire (InHypo-DMPQ) was administered to a population-based panel of adult Canadians with T2D treated with insulin and/or secretagogues. Questions pertained to respondents’ past hypoglycemia events as well as socio-demographic and clinical characteristics, including hypoglycemia unawareness. Univariable analyses (p≤0.20) followed by a multivariable zero-inflated negative binomial (ZINB) analysis were performed to explore the influence of potential risk indicators on the occurrence of any and repeated SH events. The current evaluation is based on a cohort of 436 respondents (mean age: 53 years; male: 54%). Among these individuals, 37.8% (95% CI: 33.3%-42.4%) self-reported at least one SH event in the past year; the incidence rate was 2.4 events (95% CI: 2.26-2.55) per person-year. Based on the ZINB analysis, only non-severe (NH) hypoglycemia was independently associated with SH, holding other indicators constant. Among respondents who reported ≥1 (vs. zero) NH events, the odds of never experiencing an SH event decreased by 82% (95% CI: 39.3%-94.7%, p=0.006). Likewise, a history of NH, among those who had a chance of experiencing SH, increased the expected rate of SH by a factor of 4.29 (95% CI: 2.25-8.17, p Real-world estimates of SH in T2D are often limited by sub-optimal reporting and gaps in clinical practice. To help clarify the true frequency of SH, this large, population-based study leveraged the value and clinical relevance of self-reported hypoglycemia data. The results of this study suggest that the burden of third-party assisted SH is substantial in people with T2D. Clinical strategies to prevent NH may reduce the risk of any/repeated SH events and resulting sequelae. Disclosure A. Ratzki-Leewing: None. S.

OBJECTIVE To examine the prospective associations of baseline vitamin D [25-hydroxyvitamin D; 25(OH)D] with insulin resistance (IR), β-cell function, and glucose homeostasis in subjects at risk for type 2 diabetes. RESEARCH DESIGN AND METHODS We followed 489 subjects, aged 50 ± 10 years, for 3 years. At baseline and follow-up, 75-g oral glucose tolerance tests (OGTTs) were administered. IR was measured using the Matsuda index (ISOGTT) and the homeostasis model assessment of IR (HOMA-IR), β-cell function was determined using both the insulinogenic index divided by HOMA-IR (IGI/IR) and the insulin secretion sensitivity index-2 (ISSI-2), and glycemia was assessed using the area under the glucose curve (AUCglucose). Regression models were adjusted for age, sex, ethnicity, season, and baseline value of the outcome variable, as well as baseline and change in physical activity, vitamin D supplement use, and BMI. RESULTS Multivariate linear regression analyses indicated no significant association of baseline 25(OH)D with follow-up ISOGTT or HOMA-IR. There were, however, significant positive associations of baseline 25(OH)D with follow-up IGI/IR (β = 0.005, P = 0.015) and ISSI-2 (β = 0.002, P = 0.023) and a significant inverse association of baseline 25(OH)D with follow-up AUCglucose (β = −0.001, P = 0.007). Progression to dysglycemia (impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes) occurred in 116 subjects. Logistic regression analyses indicated a significant reduced risk of progression with higher baseline 25(OH)D (adjusted odds ratio 0.69 [95% CI 0.53–0.89]), but this association was not significant after additional adjustment for baseline and change in BMI (0.78 [0.59–1.02]). CONCLUSIONS Higher baseline 25(OH)D independently predicted better β-cell function and lower AUCglucose at follow-up, supporting a potential role for vitamin D in type 2 diabetes etiology.

The Oji-Cree population of the Sandy Lake region of Ontario, Canada, has the third highest prevalence of type 2 diabetes in the world. Changes in their diet and physical activity over the past half-century, particularly the marked increase in consumption of dietary fats, are felt to be important factors accounting for this epidemic. The aim of the present study was to examine the beta-cell response to a 48-h approximately twofold elevation of plasma free fatty acids (FFAs) (induced by Intralipid and heparin infusion) in members of the Sandy Lake Oji-Cree population (n = 12) and to compare the response to that in healthy age-matched nondiabetic Caucasian subjects (n = 16). The insulin secretion rate, insulin sensitivity index (S(I)), and disposition index (D(I)) (an index of insulin secretion that takes into account the ambient S(I)) were assessed in response to a 4-h graded intravenous glucose infusion followed by a 20 mmol/l 2-h hyperglycemic clamp. Total insulin secretory response to the graded glucose infusion did not change after a 48-h FFA elevation versus saline control in Caucasians and increased by approximately 30% in Oji-Cree individuals (P = 0.04 for difference between the two groups). Infusion of heparin-Intralipid reduced S(I) by approximately 40% in both groups (P = 0.002). Although D(I) was markedly reduced by heparin-Intralipid infusion in Caucasians (by approximately 40%), it was reduced by only 15% in Oji-Cree individuals (P = 0.03 for difference of response between the two groups). However, S(I) and D(I) in the Oji-Cree individuals were already much lower than in Caucasians at baseline, in keeping with the very high risk of type 2 diabetes in this population. It is concluded that Oji-Cree individuals from a community at very high risk for developing type 2 diabetes are not more susceptible to the FFA-induced desensitization of glucose-stimulated insulin secretion than healthy non-Natives and, in fact, appear to be less susceptible. Whether this reflects an inherent resistance to lipotoxicity or an already-present lipotoxic effect in this population will require further study.

Neurogenin3 (ngn3), a basic helix-loop-helix (bHLH) transcription factor, functions as a pro-endocrine factor in the developing pancreas: by itself, it is sufficient to force undifferentiated pancreatic epithelial cells to become islet cells. Because ngn3 expression determines which precursor cells will differentiate into islet cells, the signals that regulate ngn3 expression control islet cell formation. To investigate the factors that control ngn3 gene expression, we mapped the human and mouse ngn3 promoters and delineated transcriptionally active sequences within the human promoter. Surprisingly, the human ngn3 promoter drives transcription in all cell lines tested, including fibroblast cell lines. In contrast, in transgenic animals the promoter drives expression specifically in regions of ngn3 expression in the developing pancreas and gut; and the addition of distal sequences greatly enhances transgene expression. Within the distal enhancer, binding sites for several pancreatic transcription factors, including hepatocyte nuclear factor (HNF)-1 and HNF-3, form a tight cluster. HES1, an inhibitory bHLH factor activated by Notch signaling, binds to the proximal promoter and specifically blocks promoter activity. Together with previous genetic data, these results suggest a model in which the ngn3 gene is activated by the coordinated activities of several pancreatic transcription factors and inhibited by Notch signaling through HES1.
