Effects of Liraglutide on Worsening Renal Function Among Patients With Heart Failure With Reduced Ejection Fraction: Insights From the FIGHT Trial.

ABSTRACT:

Background

The FIGHT (Functional Impact of GLP-1 [glucagon-like peptide-1] for Heart Failure Treatment) trial randomized 300 patients with heart failure with reduced ejection fraction (HFrEF) and a recent hospitalization for heart failure to liraglutide versus placebo. While there was no difference in the primary outcome (rank score of time to death, time to rehospitalization for heart failure, and change in NT-proBNP [N-terminal pro-B-type natriuretic peptide]), there was a significant increase in cystatin C among patients randomized to liraglutide raising concern of adverse renal outcomes. We performed a post hoc analysis of FIGHT to investigate whether liraglutide was associated with worsening renal function (WRF).

Methods

The relationship between randomization to liraglutide and WRF was evaluated using logistic regression models. Two hundred seventy-four patients (91%) had complete data to assess for WRF defined as: increase in SCr ≥0.3 mg/dL, or ≥25% decrease in estimated glomerular filtration rate, or an increase in cystatin C ≥0.3 mg/L from baseline to 180-days.

Results

Patients with WRF (n=113, 41%), compared with those without, were older, had more comorbidities, and lower utilization of guideline-directed medical treatment. Logistic regression models showed that age and baseline cystatin C levels were associated with WRF. In adjusted models, liraglutide was not associated with excess risk of WRF compared with placebo (odds ratio, 1.02 [95% CI, 0.62-1.67]). There was also no difference in the rank score when WRF was added as a fourth-tier outcome.

Conclusions

Liraglutide was not associated with WRF among patients with HFrEF and a recent hospitalization for heart failure. These data support the relative renal safety profile of liraglutide among patients with HFrEF. Registration: URL: http://www.clinicaltrials.gov. Unique identifier: NCT01800968.

Project description:IntroductionA worsening heart failure event (WHFE) is defined as progressively escalating heart failure signs/symptoms requiring intravenous diuretic treatment or hospitalization. No studies have compared the burden of chronic heart failure with reduced ejection fraction (HFrEF) following a WHFE versus stable disease to inform healthcare decision makers.MethodsA retrospective study using the IBM® MarketScan® Commercial Database included patients younger than 65 years of age with HFrEF (one inpatient or two outpatient claims of systolic HF or one outpatient claim of systolic HF plus one outpatient claim of any HF). The first claim for HFrEF during 2016 was the index date. Patients were followed for the first 12 months after the index date (the worsening assessment period) to identify a WHFE, and for an additional 12 months or until the end of continuous enrollment (the post-worsening assessment period). Mean per patient per month (PPPM) health care resource use (HCRU) and costs were compared between patients following a WHFE and stable patients during the two periods using generalized linear models adjusting for patient characteristics.ResultsOf 16,646 patients with chronic HFrEF, 26.8% developed a WHFE. Adjusted all-cause hospitalizations (0.16 vs. 0.02 PPPM, P < 0.0001), outpatient visits (3.54 vs. 2.73 PPPM, P < 0.0001), and emergency department visits (0.25 vs. 0.06 PPPM, P < 0.0001) were higher in patients following a WHFE than stable patients during the worsening assessment period. Similar differences in HCRU were observed between the two cohorts during the post-worsening assessment period. Mean total adjusted cost of care PPPM was $8657 in patients with HFrEF following a WHFE versus $2195 in stable patients during the worsening assessment period, and $6809 versus $2849, respectively, during the post-worsening assessment period.ConclusionHCRU and costs were significantly greater in patients with chronic HFrEF following a WHFE compared to those who remained stable, suggesting an unmet need to improve clinical and economic outcomes among these patients.
