Empagliflozin in Diuretic Refractory Ascites

Phase 1

Completed

• Conditions: Sodium-Glucose Transporter 2 Inhibitors; Liver Cirrhosis; Cirrhosis; Ascites; Ascites Hepatic
• Interventions: Drug: Empagliflozin 10 MG

• Registration Number: NCT05013502
• Lead Sponsor: Stanford University

Brief Summary

Ascites is the most frequent complication of liver cirrhosis and results in increased morbidity and mortality but current medical management options are limited. Here, the investigators will conduct an interventional single-arm pilot clinical trial toevaluate the feasibility of empagliflozin in managing diuretic-resistant ascites in patients with decompensated cirrhosis. This single site, open label pilot study will enroll participants with decompensated cirrhosis at a single site. Participants will receive empagliflozin 10mg oral tablets once daily for 12 weeks with monitoring for safety and adverse events.

Detailed Description

Pharmacologic options for the management of ascites are limited to diuretics only. Each year approximately 10% of patients with cirrhosis develop diuretic-resistant ascites, necessitating the use of more invasive procedures such a paracentesis, transjugular intrahepatic portosystemic shunting (TIPS), and transplantation; each modality is associated with significant risks and limitations. Patients treated with diuretics may also develop complications such as acute kidney injury, encephalopathy, muscle cramping, or hyponatremia, limiting optimal dosages of these medications and hence, resulting in inadequate control of fluid retention. Thus, ascites that is resistant to our current therapies is an important unmet medical need.

Recently, SGLT2-Is have been shown to reduce heart failure hospitalizations and cardiovascular death in patients with and without diabetes in landmark, large-scale clinical trials. Empagliflozin improved heart failure outcomes without altering hemoglobin A1c or increasing risk of hypoglycemia in individuals without diabetes, suggesting that SGLT2-Is may act through a neurohormonal mechanism independent of blood glucose changes. Because cirrhosis and heart failure are disorders with a common pathophysiology of decreased effective arterial blood volume with resultant stimulation of the renin-angiotensin-aldosterone system (RAAS), sympathetic nervous system, and total body fluid overload, the investigators hypothesize that SGLT2-Is may be effective in the management of ascites. Multiple lines of evidence suggest SGLT2-Is may have a beneficial role in chronic liver disease. Several case reports of patients with cirrhosis and diuretic-resistant ascites have found that SGLT2-I treatment was associated with near resolution of ascites and pedal edema. SGLT2-I treatment has also demonstrated improved hepatic function, reduction of fibrosis and normalization of liver enzymes in non-alcoholic fatty liver disease (NAFLD).Although SGLT2-I are partially cleared by the liver, empagliflozin is well tolerated in patients with cirrhosis. Thus, the investigators initiated a feasibility study to test the hypothesis that the SGLT2-I, empagliflozin, will decrease ascites by attenuating maladaptive neurohormonal and inflammatory responses in cirrhosis.
