Trial Summary

What is the purpose of this trial?

The purpose of this study is to prospectively assess the impact of TIPS creation on muscle mass and physical function in patients with cirrhosis, and to determine whether these changes correlate with improved outcomes in patients awaiting liver transplantation. Retrospective observational studies have shown improvement in muscle mass and body composition in cirrhotic patients undergoing TIPS. The investigators aim to now prospectively study this through a pilot randomized controlled trial tracking patients managed with TIPS creation compared to those managed without TIPS to determine whether these observational findings can be seen in a randomized cohort. The investigators hypothesize that TIPS creation will lead to improved muscle mass, body composition and muscle function within the first 12 months after the procedure compared to a control group without TIPS, and that these changes will improve liver disease outcomes in patients awaiting liver transplantation.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the TIPS treatment for liver cirrhosis and muscle loss?

TIPS is effective in treating complications of severe portal hypertension, such as variceal bleeding, and has a high technical success rate with most patients showing clinical improvement. It is also used in managing conditions like Budd-Chiari syndrome and has a low complication rate, although long-term shunt patency remains a concern. ^{1 2 3 4 5}

Is the TIPS procedure generally safe for humans?

The TIPS procedure is generally considered safe, with a high technical success rate and clinical improvement in most patients. However, some complications can occur, such as encephalopathy (a brain condition that affects thinking and behavior), and there is a risk of mortality, especially in patients with severe liver disease. ^{1 6 7 8 9}

How does the TIPS procedure differ from other treatments for liver cirrhosis and muscle loss?

The TIPS procedure is unique because it is a minimally invasive treatment that creates a shunt (a passage) inside the liver to reduce high blood pressure in the portal vein, which can help prevent complications like bleeding and fluid buildup. Unlike traditional surgery, it avoids the risks of general anesthesia and major surgery, making it a safer option for patients with liver cirrhosis. ^{1 2 10 11 12}

Research Team

Eligibility Criteria

This trial is for adults aged 18-99 with cirrhosis listed for liver transplant, experiencing complications like persistent fluid buildup or bleeding due to portal hypertension. It's not suitable for those with frequent brain function issues from liver disease, severe clotting problems, current infections, pregnancy, urgent need for TIPS, no other treatment options, active cancer outside the liver or a MELD score over 25.

Inclusion Criteria

I need a procedure to open a blocked vein in my liver for a transplant.

I have stomach issues due to liver problems and anemia from bleeding.

I am between 18 and 99 years old, have cirrhosis, and am on the liver transplant list.

Exclusion Criteria

I am unable to make my own medical decisions.

I have had more than one episode of severe confusion due to liver problems.

I have no other treatment options besides TIPS for my condition.

Treatment Details

Interventions

• Transjugular Intrahepatic Portosystemic Shunt (TIPS) creation (Procedure)

Trial Overview The study tests if creating a Transjugular Intrahepatic Portosystemic Shunt (TIPS) in cirrhotic patients improves muscle mass and physical function compared to those without TIPS. The goal is to see if these changes lead to better outcomes while waiting for a liver transplant.

Participant Groups

Group I: TIPS Experimental Treatment 1 Intervention

Patients in this arm will undergo TIPS creation in addition to their current management.

Group II: Standard of care Active Control 1 Intervention

Patients in this arm will continue to be treated with their current management

Transjugular Intrahepatic Portosystemic Shunt (TIPS) creation is already approved in Canada for the following indications:

Approved in Canada as TIPS for:

• Refractory ascites
• Variceal bleeding
• Hepatic hydrothorax

Findings from Research

The transjugular intrahepatic portosystemic shunt (TIPS) procedure has a high technical success rate of 95% and effectively prevents rebleeding from esophageal varices, showing clinical improvement in 93% of patients.

While TIPS carries a lower risk than surgical alternatives and has no immediate mortality, 17% of patients experienced encephalopathy requiring treatment, indicating the need for careful monitoring post-procedure.

In a study of 467 patients with cirrhosis undergoing TIPS for variceal bleeding, those with spontaneous portosystemic shunts (SPSSs) experienced similar long-term outcomes and safety profiles compared to those without SPSSs, indicating that TIPS is effective for both groups.

The procedure was safe, with only one case of asymptomatic pulmonary embolism and one case of serious gastric ulcer bleeding in the SPSS group, and overall complication rates were not significantly different between the two groups during a median follow-up of over 2 years.

Transjugular intrahepatic portosystemic shunts (TIPS) is a minimally invasive surgical technique that effectively treats portal hypertension, reducing risks associated with general anesthesia and major surgeries.

The first reported case of TIPS in Brazil for a cirrhotic alcoholic patient highlights its potential as a bridge to liver transplantation, improving surgical outcomes and reducing complications like bleeding and the need for blood transfusions.
