Empagliflozin may not exhibit clinical or mortality benefit in COVID-19 patients
The RECOVERY trial has concluded that empagliflozin, a drug proposed for its anti-inflammatory and metabolic effects, does not provide substantial benefits or effects for COVID-19 treatments in patients hospitalized with the virus. The critical findings were published in The Lancet Diabetes & Endocrinology.
This randomized, controlled, open-label study was aimed to assess the safety and efficacy of empagliflozin in COVID-19 patients. From July 28, 2021 to March 6, 2023, a total of 4271 patients were randomly assigned to receive either empagliflozin (2113 patients) or usual care alone (2158 patients).
The primary outcome of 28-day mortality showed no significant difference between the two groups, with a mortality rate of 14% in both the empagliflozin and usual care groups. Also, secondary outcomes, including the duration of hospitalization and the composite of invasive mechanical ventilation or death, did not reveal observable distinctions.
The data monitoring committee recommended a review of the data on March 3, 2023, leading to the halt of recruitment on March 7, 2023. Notably, two serious adverse events believed to be related to empagliflozin were reported, both involving ketosis without acidosis.
The findings suggest that empagliflozin, at a dosage of 10 mg once daily for 28 days or until discharge, does not confer a significant advantage in terms of mortality, hospitalization duration, or the risk of progression to invasive mechanical ventilation or death in adults hospitalized with COVID-19.
Empagliflozin, commonly used in the treatment of diabetes, does not appear to be a recommended intervention for COVID-19 unless there is a pre-existing indication for its use due to another condition. This outcome underscores the complexity of finding effective therapeutics for COVID-19 and emphasizes the importance of evidence-based, thoroughly tested treatments in the ongoing battle against the pandemic.
