Plain-language summary
This study is a prospective, randomized, double-blinded, parallel-controlled, multi-central clinical trial for patients with severe acute pancreatitis (SAP). Patients with SAP in the early stage (within 7 days of onset) and over the age of 18, based on the routine treatment, will be randomly divided into a high-dose intravenous vitamin C group (HDIVC, 500mg/kg/24h, administered by iv. pump at a rate of 2g/h for 7 days) and a control group (an equal volume of normal saline). The primary endpoint is mortality rate in ICU, and secondary endpoints include free organ support duration (FOSD) within 14 days after enrollment, changes in inflammatory response and severity, disease severity scores and changes, fluid retention, incidence of infectious pancreatic necrosis (IPN), ICU mortality, pancreatic necrosis scores, monitoring of vitamin C plasma concentrations before and after HDIVC use, composition of gut microbiota, observation of vitamin C-related adverse reactions. The study hypothesis is that HDIVC can reduce mortality rate in ICU, significantly decrease the FOSD within 14 days and significantly reduce inflammatory response, decrease fluid retention, and improve disease severity.

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.
