E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
We will investigate the potential benefit of early administration of high doses of Vitamin C in addition to standard care in patients with sepsis or septic shock. |
|
E.1.1.1 | Medical condition in easily understood language |
Sepsis and septic shock are potentially life-threatening conditions characterized by a deregulated body's response to infection causing injury to its own tissues and organs. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the trial is to evaluate the efficacy of early administration of Vitamin C in addition to the standard of care in patients with sepsis or septic shock. This will be done by determining the average post-baseline patient SOFA score (on day 1-5 after patient inclusion). The SOFA score is widely employed in daily monitoring of acute morbidity and is an acceptable surrogate marker of efficacy in exploratory trials of novel therapeutic agents in sepsis. We aim to proof that through early admission of Vitamin C, patients who present at an early stage of the disease course will get less sick, resulting in a lower max SOFA score. However, administration of Vitamin C in our sickest population might not necessarily reflect in a lower max SOFA score, but rather in faster recovery (higher delta SOFA between 2 points in time). To capture both phenomena, we will look at the average post-baseline SOFA score as primary outcome supported by a maximum SOFA score as secondary outcome |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to evaluate other patient oriented outcome measures and cost-effectiveness of Vitamin C. o Maximal SOFA score o Length of hospital stay (days) o Length of ICU stay o 28-day mortality o Ventilator days during hospital admission o Steroid use o Total dose of steroids given (d1-d5) o Total duration and dosage during admission o RRT duration and need during hospital admission o EQ-5D-5L health questionnaire at baseline, day 5, day 28 and month 3 in the view of a possible health economic analysis. If the patient's clinical status doesn't allow self-completion, the questionnaire may becompleted by proxy. o Time to return to work (if applicable) o Changes in creatinine, CRP and sodium over time (d1-5) (part of standard of care). o Changes in procalcitonin between d1 and d4 |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Participants eligible for inclusion in this trial must meet all of the following criteria: 1. Patient is ≥ 18 years old. 2. Patient has a 'suspected infection': this requires the combination of AB administration and body fluid cultures within the first 6 hours after ED presentation. 3. NEWS score ≥ 5.
NEWS is based on a simple aggregate scoring system in which a score is allocated to physiological measurements, already recorded in routine practice, when patients present to the hospital. Six simple physiological parameters form the basis of the scoring system: respiration rate, oxygen saturation, systolic blood pressure, pulse rate, level of consciousness or new confusion and temperature. |
|
E.4 | Principal exclusion criteria |
Participants eligible for this trial must not meet any of the following criteria: 1. Patient (≥18 years old) or legally authorized representative (LAR) didn't provide informed consent. Delayed informed consent can be applied in cases where the patient is critically ill and no LAR is available 2. AB administration as a single dose or as a prophylactic treatment. 3. AB administered without an accompanying body fluid culture according to the timeframe (within 6 hours after ED presentation). 4. 'Do no intubate' or 'comfort measures only' status. 5. Failure to randomize within 6 hours. 6. Weight < 45 kg. 7. Pregnant or breastfeeding. 8. Allergy for Vitamin C. 9. Known history of oxalate nephropathy or hyperoxaluria. 10. Known history of glucose-6-phosphate dehydrogenase deficiency. 11. Known history of chronic iron overload due to iron storage and other diseases. 12. The patient is already on IV steroids for a reason other than septic shock. 13. Proven active COVID-19 infection (positive swab and/or CT scan positive for COVID). |

E.5 End points |
E.5.1 | Primary end point(s) |
Clinical Severity SOFA score: o Average post-baseline patient SOFA score (on day 1-5 after patient randomisation). o To avoid missing data for deceased patients, the maximum SOFA score of 24 will be assigned to mortality. Missing values for the non-deceased patients will be imputed (see statistical analysis plan). o The SOFA score is a morbidity/mortality prediction score based on the degree of dysfunction of 6 organ systems: the respiratory, cardiovascular, hepatic, coagulation, renal and neurological systems. Organ scores range from 0 to 4, with the best score being 0 and the worst score being 4. The higher the SOFA score, the higher the likely mortality. |
