An investigation into the durability of glycemic control in patients with type II diabetes initiated on canagliflozin or sitagliptin: A real-world analysis of electronic medical records
Journal of Diabetes and its Complications, 2019
The aims of this study were to assess glycemic control, weight loss, and durability of glycemic control in patients initiated on canagliflozin (CANA) versus sitagliptin (SITA).
Adults with type II diabetes mellitus initiated on CANA or SITA (index date) were identified from IQVIA™ Real-World Data Electronic Medical Records - US database (03/29/2012-04/30/2016). Inverse probability of treatment weighting accounted for baseline differences between cohorts. Outcomes were compared using weighted Cox regression and Kaplan-Meier curves and included time to reaching HbA1c thresholds (<7%[53 mmol/mol], <8%[64 mmol/mol], <9%[75 mmol/mol]), weight loss ≥5%, failure to maintain HbA1c below threshold, new antihyperglycemic (AHA) prescription, and failure to maintain HbA1c/new AHA prescription.
Weighted cohorts were well balanced (NCANA = 14,542; NSITA = 15,151). CANA patients were 12-15% more likely to reach the HbA1c thresholds, 47% more likely to lose ≥5% of body weight, 31% less likely to have a new AHA prescription, 10-15% less likely to fail to maintain HbA1c, and 13-26% less likely to fail to maintain HbA1c or have a new AHA, versus SITA patients.
CANA patients were more likely to reach HbA1c and weight loss thresholds and maintain HbA1c below threshold versus SITA patients, while being less likely to have a prescription for a new AHA, suggesting more durable glycemic control with CANA.
