This study compared HbA1c control, treatment patterns, and costs in adults with T2DM initiated on CANA or a GLP-1 based on administrative claims data from the HealthCore Integrated Research Database (4/2013-02/2016) augmented with laboratory data. The analysis included adult patients with ≥1 HbA1c result at baseline (BL) and in the 12-month follow-up period; statistical analysis was performed at 3-month intervals. Inverse probability of treatment weighting (IPTW) accounted for differences in BL characteristics. From 12 months pre- to 12 months post-index (Figure), there were no significant differences in HbA1c at each 3-month interval in patients initiated on CANA (n = 750) or GLP-1 (n = 2417); results were consistent regardless of BL HbA1c (≥7%, ≥8%, or ≥9%) (data not shown). A greater proportion of patients were adherent to index medication (proportion of days covered ≥80%) over 12 months with CANA vs. GLP-1 (47.5% vs. 37.5%; P <0.001). The likelihood of discontinuation from index medication was lower with CANA than GLP-1 (49.6% vs. 57.4%; HR [95% CI]: 0.78 [0.70, 0.88]). Continuous 12-month pharmacy costs were $1,421 lower with CANA vs. GLP-1.
In summary, CANA initiation resulted in similar HbA1c values, greater adherence, less discontinuation, and lower treatment cost compared to GLP-1 in T2DM patients.
