Abstract Introduction Sepsis is a severe disease with a complex pathogenesis and is an important factor in the mortality of patients in intensive care units (ICUs). The administration of vitamin C and its combination treatment in sepsis was not supported by the results of multiple randomized controlled clinical trials. However, the efficacy of a higher vitamin C dose in treating patients with sepsis remains unclear. Therefore, the effectiveness of administering a larger dosage of vitamin C to patients with sepsis remains unclear. Methods and Analysis The Clinical Efficacy of Megadose Vitamin C in Sepsis (CEMVIS) trial is a multicenter, single-blind, randomized, placebo-controlled trial with 234 individuals with sepsis. The following adult patients will be enrolled: those with procalcitonin (PCT) ≥ 2 ng/mL and sepsis 3.0 diagnostic criteria. Patients will be randomly assigned to receive 12 g vitamin C or the same volume of 5% glucose injection intravenously pumped every 12 h for 4 days or up to the moment they are discharged from ICU. The primary outcome will be the mortality within 28 days. Secondary outcomes will mainly include protection and support of organ functions, improvement in inflammatory status, and length of ICU stay. Moreover, adverse events and serious adverse events will be meticulously recorded. Ethics This study was approved by the Clinical Ethics Committee of Zhujiang Hospital of Southern Medical University (2020-KY-069-05). The trial results will be published in peer-reviewed journals or at national or international conferences.
