Improvement in Patient-Reported Outcomes in Adults with Type 1 Diabetes Treated with Sotagliflozin plus Insulin...

Diabetes-related distress is common among persons affected by diabetes and is associated with suboptimal glycemic control and complications, thus constituting a relevant patient-report outcome (PRO). Improving glycemic control may reduce diabetes distress and improve treatment satisfaction. This post hoc analysis evaluated PRO data for a pooled cohort of adults with type 1 diabetes (T1D) receiving sotagliflozin as adjunct to optimized insulin in the inTandem1 and inTandem2 studies. Clinically meaningful changes in the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and the two-item Diabetes Distress Scale (DDS2) total and individual scores were examined in the pooled data from the first 24 weeks of the studies. In the cohort of patients with a baseline DTSQs total score ≤32 (∼76% of entire cohort), nearly twice as many patients treated with sotagliflozin 200 (45.9%) or 400 mg (42.3%) experienced a >3-point improvement from baseline versus those treated with placebo (24%). Treatment with sotagliflozin led to statistically significant (P < 0.05) improvements across all DTSQs items. Approximately 42% of all patients were considered to have a high risk of diabetes distress (total DDS2 score ≥6) at baseline following insulin optimization. More patients shifted from high to low risk with sotagliflozin compared with placebo (∼40% vs. 23%; P ≤ 0.0002). The baseline-adjusted difference in DDS2 from placebo was significantly (P < 0.001) reduced by -0.5 and -0.6 for sotagliflozin 200 and 400 mg, respectively. Patients with T1D treated with sotagliflozin in addition to optimized insulin therapy reported meaningful improvements in treatment satisfaction and diabetes distress. NCT02384941 and NCT02421510.
