Abstract
AimsExamine real‐world outcomes in patients with type 2 diabetes mellitus (T2DM) initiating injectable therapy as part of the Initiation of New Injectable Treatment Introduced after Antidiabetic Therapy with Oral‐only Regimens (INITIATOR) study.Materials and methodsLinked insurance claims and medical record data were collected from 2 large US health insurers (April 1, 2010 to March 31, 2012) of T2DM adults initiating treatment with glargine (GLA) or liraglutide (LIRA). Baseline characteristics were examined and changes in 12‐month follow‐up outcomes were described for both treatment groups: HbA1c, weight change, hypoglycaemia, persistence, healthcare utilisation and costs.ResultsA total of 4490 patients were included (GLA, 2116; LIRA, 2374). At baseline, GLA patients had significantly higher HbA1c vs LIRA patients (9.72% vs 8.19%; P < .001), lower likelihood of having HbA1c < 7% (7.1% vs 23.8%; P < .001), lower bodyweight (100.9 kg vs 110.9 kg, P < .001), higher Charlson Comorbidity Index score (0.88 vs 0.63; P < .001), and higher diabetes‐related costs ($3492 vs $2089; P < .001), respectively.During 12‐months of follow‐up, treatment persistence was 64%, mean HbA1c reduction was −1.24% and weight change was + 1.17 among GLA patients, and was 49%, −0.51% and −2.74 kg, respectively, among LIRA patients. Diabetes‐related costs increased significantly from baseline to follow‐up for LIRA patients ($2089 vs $3258, P < .001) but not for GLA patients ($3492 vs $3550, P = .890).ConclusionsThere were clinically relevant baseline differences in both groups, suggesting that GLA and LIRA are prescribed for different patient groups, and highlighting that efficacy results from clinical trials do not always translate into real‐world practice. Significant increases in healthcare costs were observed in the LIRA group, warranting further cost‐effectiveness analysis.
