Can dapagliflozin be given by enteral tube?

Comment by InpharmD Researcher

Limited data are available to guide the administration of dapagliflozin via enteral feeding tubes. While the package insert for Farxiga (dapagliflozin) does not specify alternative routes and Xigduo XR (dapagliflozin/metformin) advises against crushing its extended-release tablets, two randomized clinical trials (Tables 1 and 2) have described the use of crushed or macerated dapagliflozin tablets mixed with water and administered via oroenteral, orogastric, gastrostomy, or jejunostomy tubes. Overall, due to the limited supporting evidence, administration of dapagliflozin via enteral feeding tubes should be approached with caution.

Background

A 2024 multicenter, randomized, open-label clinical trial, conducted across 22 intensive care units (ICUs) in Brazil, evaluated whether the addition of dapagliflozin to standard care improves clinical outcomes in critically ill patients with acute organ dysfunction. The trial enrolled 507 participants, aged 18 years or older, who had unplanned ICU admissions and presented with at least one organ dysfunction (e.g., respiratory failure, cardiovascular instability, or acute kidney injury). Participants were randomized 1:1 to receive either 10 mg of dapagliflozin orally or standard ICU care alone for up to 14 days or until ICU discharge. For patients with a contraindication to oral medication, dapagliflozin was administered enterally via oroenteral, orogastric, gastrostomy, or jejunostomy tube, following maceration and dilution in water. The primary outcome was a hierarchical composite of hospital mortality, initiation of kidney replacement therapy (KRT), and ICU length of stay, analyzed using the win ratio method. According to findings, the win ratio for this primary composite outcome was 1.01 (95% CI, 0.90-1.13; P=.89), indicating no significant advantage of dapagliflozin over standard care. [1]

A 2021 randomized, double-blind, placebo-controlled, international Phase III trial, known as the DARE-19 study, was conducted to evaluate the efficacy of dapagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, in reducing major clinical events and improving recovery in patients hospitalized with COVID-19. The trial enrolled approximately 1200 non-critically ill adult patients from multiple countries who had at least one cardiometabolic risk factor (such as hypertension or type 2 diabetes). Participants were randomized 1:1 to receive either 10 mg of dapagliflozin or a placebo for 30 days, followed by a 60-day observational period. Treatment with dapagliflozin or matching placebo was continued even if mechanical ventilation became necessary; in this scenario, the tablets were crushed and administered via the gastric tube. This trial was the first to explore the potential benefits of SGLT2 inhibitors in the context of COVID-19. Results indicated that treatment with dapagliflozin did not result in a statistically significant risk reduction in organ dysfunction or death, or improvement in clinical recovery, but was well tolerated.

Study Author Conclusions

The addition of dapagliflozin to standard care for critically ill patients and acute organ dysfunction did not improve clinical outcomes; however, confidence intervals were wide and could not exclude relevant benefits or harms for dapagliflozin.

Critique

The study was well-designed with a large sample size and multicenter approach, enhancing its generalizability. However, the open-label design may introduce bias, and the heterogeneous population may dilute potential effects in specific subgroups. The lack of blinding and absence of biological response data are notable limitations.

Study Author Conclusions

In patients with cardiometabolic risk factors hospitalised with COVID-19, treatment with dapagliflozin did not result in a statistically significant risk reduction in organ dysfunction or death, or improvement in clinical recovery, but was well tolerated.

Critique

The study was well-designed as a multicentre, randomised, double-blind, placebo-controlled trial, which is a strength. However, the lower-than-anticipated event rates due to improvements in standard care may have limited the ability to detect statistically significant differences. Additionally, the study's findings may not be generalisable to all populations due to specific eligibility criteria and the modest proportion of patients receiving remdesivir and systemic corticosteroids.
