Precise Profiling of Liver Disease Patients With DPMAS Therapy, Treating Optimal Patients and Achieving Hard Endpoint (PADSTONE Study)

China1,300 participantsStarted 2021-09-15

Plain-language summary

Acute-on-chronic liver failure (ACLF) is a life-threatening syndrome occurring in patients with chronic liver disease. In China, hepatitis B virus (HBV) is the main cause of cirrhosis. HBV related ACLF is characterized by multiple organs failure (liver, coagulation and kidney, etc.) and confers with high risk of short-term mortality. For the treatment of ACLF patients, recent studies have explored the therapeutic efficacy of extracorporeal liver support therapies, such as albumin dialysis, plasma exchange. However, the clinical efficacy remains to be fully elucidated. Liver transplantation is the most efficient way to improve the survival of ACLF patients, especially for those suffering from three or more organ failures. Recently, a novel extracorporeal system which is called double plasma molecular adsorption system (DPMAS) has been applied for the treatment of ACLF patients. DPMAS is an extracorporeal therapeutic procedure that combines two hemoperfusion devices. During treatment, toxic plasma is isolated and purified via perfusion through two adsorbers, after which the purified plasma is reinfused back into the patient's circulation. This technique requires no massive plasma supply and avoids the risks of plasma-related allergic reactions and pathogen transmission. DPMAS can rapidly alleviate jaundice and lower serum bilirubin levels, thereby mitigating the hepatotoxic effects induced by excessive bilirubin and bile acids. Despite the widespread clinical application of DPMAS in patients with liver failure, high-quality evidence supporting its definite clinical efficacy remains insufficient. Accordingly, this prospective, multicenter cluster-controlled study is designed to evaluate the clinical benefits of DPMAS via validated hard clinical endpoints, including short-term mortality and disease progression, and screen out suitable candidate patients. Furthermore, biological specimens including plasma, urine and feces will be collected to characterize the molecular profiles of ACLF patients receiving DPMAS treatment through multi-omics analyses.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
