Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be allocated in a 1:1:1 ratio to the RESPOND treatment groups.
Arm 1 - Intervention 1 - Early intravenous resuscitation with Vitamin C and Hydrocortisone.
After initial shock treatment including fluids and a first intravenous inotrope, patients then receive concomitant treatment with Vitamin C and Hydrocortisone.
Ascorbic acid (Vitamin C): the dosing schedule is 100 mg/kg (maximum 5,000 mg per dose) intravenously every 6 hours for the duration of study treatment and will be infused over 60 minutes.

Hydrocortisone: The dosing schedule is 1 mg/kg (maximum 50 mg per dose) intravenously infused over 5 minutes every 6 hours for the duration of study treatment given as a slow bolus.

Arm 2 - Intervention 2 - Hydrocortisone only.
Hydrocortisone: the dosing schedule is 1mg/kg (maximum 50 mg per dose) intravenously infused over 5 minutes every 6 hours for the duration of study treatment given as a slow bolus.

All three arms will be monitored for adherence to interventions by a formal data monitoring and audit of the medication records.

Duration of treatment
After shock resolution - defined as cessation of inotropes for at least 4 hours - or after a maximum of 72hours study drugs should be ceased. The treatment will continue until (whichever occurs first):
- Septic shock resolves defined as ability to cease inotropes for less than 4 hours with good perfusion and no signs of shock.
- 72 hours of treatment has been administered
- The patient is discharged from ICU
- Contraindications to Vitamin C or Hydrocortisone therapy arise
- Death occurs
- Serious adverse events suspected to be secondary to the intervention therapy develop

Treatment: Drugs
Comparator / control treatment
Arm 3 - Standard care: Patients in the standard treatment arm of the study can receive Hydrocortisone only if clinically indicated at the discretion of the attending ICU staff specialist.
The dose and duration of hydrocortisone in the standard care arm will be decided by the clinician, usually this would be a dose of 1mg/kg 6 hourly administered intravenously over 5 minutes.

Eligibility
Key inclusion criteria
Criterion 1: Child aged >=7 days and <18 years and admitted to PICU.
Criterion 2: Decision by treating physician to treat as sepsis (including parenteral antibiotics and inotropes)
Criterion 3: Treatment of septic shock with vasopressor/inotrope therapy for >1 hour, or at a Vasopressor-Inotrope-Score of at least 10.

Inotrope requirement will be calculated by means of the Vasoactive-Inotrope Score (VIS)63: VIS = dopamine dose (micgrogram/kg/min) + dobutamine dose (microgram/kg/min) + 100 x adrenaline dose (microgram/kg/min) + 100 x noradrenaline dose (microgram/kg/min) + 10 x milrinone dose (microgram/kg/min) + 10,000 x argipressin(vasopressin) dose (unit/kg/min). Note: vasopressin doses are often recorded as mU/kg/hour, which needs conversion to U/kg/min for the VIS score.
Minimum age

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
No blinding will be performed, all three interventions will be open labelled. The main aim of this study is investigate the effect of vitamin c and hydrocortisone while being cognisant of safety of the interventions. To ensure evidence of safety can be provided and reduce the logistic challenges with blinding three arms, it is acceptable to perform this study as a open label format.
Allocation concealment will occur by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be performed by the site investigator or research coordinator opening the next sequential sealed opaque envelope which are prepared using a randomization sequence provided by The University of Queensland, Child Health Research Centre.
Variable block randomisation will be used to allocate children in a 1:1:1 ratio stratified by administration of steroids prior to enrolment, and site

Statistical methods / analysis
Descriptive statistics will be utilised to report on the baseline characteristics of the total study cohort and each subgroup, as well as by site. The primary outcome measure will be analysed using competing-risks regression. Stratification variables (administration of steroids prior to enrolment, and site) will be accounted for as fixed effects in the model. Analysis of secondary outcomes will be undertaken using a similar approach using appropriate regression models for the outcome under investigation. Main analyses will be by intention-to-treat. Per-protocol analyses will be performed as well and compared to intention-to-treat. Statistical significance will be set at the 0.05 level for the primary outcomes. Post-hoc power analyses may be undertaken to determine if results found in sub-group analyses are reliable.
