Clinical Trial Summary

In this multicenter, randomized, single-blind, placebo-controlled clinical trial. Patients will be randomly assigned to receive Vitamin C or placebo for 4 days or until ICU discharge (whatever come first). The primary outcome is 28-day all-cause mortality.


Description:

Investigational drug: Vitamin C for injection Study title: Clinical efficacy of megadose vitamin C in sepsis (CEMVIS): A Multicenter, Randomized, Single-blind, Placebo-controlled Clinical Trial Principal Investigator: Zhanguo Liu, professor, Department of Critical Care Medicine, Zhujiang Hospital, Southern Medical University Study subjects: Adult septic/septic shock patients with procalcitonin(PCT)≥2ng/ml at recruitment. Study phase: Investigator Initiated Trial(IIT) Study objectives: The objective of the study is to determine whether megadose vitamin c, compared to placebo, improve the prognosis of sepsis, including the reduction in mortality, the protection of organ function and reduction of inflammatory response, and to determine the safety of megadose vitamin c in patients with sepsis. Study design: A Multicenter, Randomized, Single-blind, Placebo-controlled Clinical Trial Method: Megadose vitamin C group: routine treatment follow the recommendation of the guidelines for sepsis in 2021+ 12 g vitamin C (48 ml) injection every 12 h for 4 days or until ICU discharge (death or transfer from ICU to general ward or discharge), whatever come first. Placebo control group: routine treatment follow the recommendation of the guidelines for sepsis in 2021 + 48ml 5% glucose injection every 12 h for 4 days or until ICU discharge (death or transfer from ICU to general ward or discharge), whatever come first.

Secondary Sequential Organ Failure Assessment (SOFA) score Organ dysfunction assessed by Sequential Organ Failure Assessment (SOFA) score. SOFA score is based on six different scores, one each for the respiratory, cardiovascular, hepatic, coagulation, renal and neurological systems. The highest score for each of the six items is 4 points, and the lowest score is 0 points. Finally, the scores of the six items are summed to get the value of the sofa score. The range of the sofa score is 0-24.Higher values represent a worse outcome. The outcome will be assessed at the 0, 1 ,2 ,4 day after enrollment
