Vitamin C, Thiamine, and Steroids in Sepsis

Trial ID or NCT#



not recruiting iconNOT RECRUITING


The VItamin C, Thiamine And Steroids in Sepsis (VICTAS) Study is a double-blind, placebo-controlled, adaptive randomized clinical trial designed to investigate the efficacy of the combined use of vitamin C, thiamine and corticosteroids versus indistinguishable placebos for patients with sepsis. The objective of this study is to demonstrate the efficacy of combination therapy using vitamin C, thiamine and corticosteroids in reducing mortality and improving organ function in critically ill patients with sepsis.

Official Title

A Multi-center, Randomized, Placebo-controlled, Double-blind, Adaptive Clinical Trial of Vitamin C, Thiamine and Steroids as Combination Therapy in Patients With Sepsis.

Eligibility Criteria

Ages Eligible for Study: Older than 18 Years
Sexes Eligible for Study: ALL
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. * Suspected or confirmed infection as evidenced by ordering of blood cultures and administration of at least one antimicrobial agent* Anticipated or confirmed intensive care unit (ICU) admission* Acute respiratory or cardiovascular organ dysfunction attributed to sepsis as evidenced by at least one of the following requirements:
    1. 1. Vasopressor Requirement - Continuous infusion of norepinephrine, epinephrine, vasopressin, dopamine, phenylephrine or other vasopressor agents at any dose for greater than 1 hour and required to maintain a mean arterial pressure ≥ 65 mm Hg despite intravenous crystalloid infusion of at least 1000cc 2. Respiratory Support Requirement - Acute hypoxemic respiratory failure defined as persistent hypoxemia (partial pressure of arterial oxygen (PaO2)/fraction of inspired oxygen (FiO2) ≤ 300 or blood oxygen saturation (SpO2)/FiO2 ≤ 315) requiring (1) intubation and mechanical ventilation, or (2) positive pressure ventilation via tight-fitting face mask (i.e. continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) or (3) high flow nasal cannula ≥ 40 liter per minute (LPM) flow and FiO2 ≥ 0.40
Exclusion Criteria:
  1. * Weight \< 40 kilograms (kg)* Prior enrollment in this study* Qualifying organ dysfunction no longer present at the time subject would be randomized* Cardiovascular or respiratory organ failure caused by an illness other than sepsis* First episode of qualifying organ dysfunction during the current emergency department (ED) or ICU admission occurred \> 24 hours before the subject could be randomized* Limitations of care (defined as refusal of cardiovascular and respiratory support modes) including "do not intubate" (DNI) status* Current hospitalization \> 30 days at time of randomization* Chronic hypoxemia requiring supplemental non-invasive oxygen (nasal cannula or NIPPV) or home mechanical ventilation* Chronic cardiovascular failure requiring home mechanical hemodynamic support (e.g., LVAD) or home chemical hemodynamic support (e.g., milrinone)* Known allergy or contraindication to vitamin C, thiamine, and/or corticosteroids (including previously or currently diagnosed primary hyperoxaluria and/or oxalate nephropathy, or known/suspected ethylene glycol ingestion, or known glucose-6-phosphate dehydrogenase (G6PD) deficiency)* Use of vitamin C at a dose of \> 1 gram daily within the 24 hours preceding first episode of qualifying organ dysfunction during a given ED or ICU admission* Chronic disease/illness that, in the opinion of the site investigator, have an expected lifespan of \< 30 days unrelated to current sepsis diagnosis (e.g., stage IV malignancy, neurodegenerative disease, etc.)* Pregnancy or known active breastfeeding* Prisoner or Incarceration* Current participation in another interventional research study* Inability or unwillingness of subject or legal surrogate/representative to give written informed consent
