Background and study aims
The treatment of critically ill patients represents a significant healthcare burden. Outside of pandemics, almost 1 in 5 patients admitted to ICUs in Scotland die during their hospital stay, and even among survivors to hospital discharge we have shown a 5-year mortality of 23% among ICU survivors. Importantly, patients surviving critical illness have a high prevalence of multimorbidity, and more have socioeconomic deprivation compared to the general Scottish population.
Precision Medicine (PM) refers to treatments that take individual variability into account and matches treatment to individual’s illness features. PM is growing in use in cancer care, providing precise treatments for patients based on their genetics. Currently it isn’t used in ICU because patients because, unlike cancer patients, they have a rapidly changing illness state. The TRAITS programme aims to enable time-critical precision medicine (TCPM) to be used in critically ill patients.

Who can participate?
Patients aged 16 years or older, receiving organ support in a critical care setting, and resident in Scotland.

What does the study involve?
• We will use routinely collected clinical data to enable efficient design, including linking clinical data from participants to collect trial defined outcomes
• We will collect blood samples to enable identification of treatable trait, changes following treatments and to help identify novel targets for future trials.
• We will run a Scotland-wide platform Randomised Controlled Drug Trial (RCT). Patients will be allocated to usual care only or to a trait linked trial treatment plus usual care.
The RCT will run multiple protocols at the same time, called Trait Specific Protocols (TSPs), which can investigate multiple treatments against pre-defined traits. Our trial design is adaptive which means we can identify new traits, introduce new treatments, and answer questions such as benefit, futility or harm as soon as sufficient data have accrued.
In summary, our clinical trial aims to enable time-critical precision medicine for critically ill patients in Scotland and inform such approaches globally.

TRAITS has 2 stages; (1) the platform and (2) the Trait Specific Protocol (TSP)
The platform requires one blood sample to be taken which will be used to identify a trait. Some baseline data will be collected from medical notes.
In the TSP, participants will be randomised to either IMP and usual care, or usual care.

What are the possible benefits and risks of participating?
Benefits:
Not provided at time of registration
Risks:
Bloods are routinely taken from ICU patients and this is always done by experienced members of the clinical team who are trained to do this. The risk for the platform are therefore very low.
If participants are randomised to receive IMP possible side effects represent a risk to participants and these are listed within the PIL but also discussed as part of the consent discussion. The side effects have been listed as common, rare etc. to help participants interpret this information.

Where is the study run from?
University of Edinburgh and NHS Lothian (ACCORD) (UK)

When is the study starting and how long is it expected to run for?
February 2023 to May 2027

Approved 11/09/2023, Scotland A Research Ethics Committee (South East Scotland Research Ethics Service, 2nd Floor Waverley Gate, 2-4 Waterloo Place, Edinburgh, EH1 3EG, United Kingdom; +44 7814609032; sesres@nhslothian.scot.nhs.uk), ref: 23/SS/0031

Health condition(s) or problem(s) studiedCritical illness
InterventionThis is a platform trial with multiple arms running within the protocol appendices called Trait Specific Protocols (TSPs). Each TSP recruits different sub set of TRAITS participants and randomises to different interventions.
1. LYMP-RESP TSP. Participants randomised to either Budesonide (1 mg every 12 h for 7 days) and usual care, OR baricitinib (4 mg per day for up to 14 days) and usual care OR usual care
2. ENDO-SHOCK TSP. Participants randomised to either imatinib (800-mg loading dose followed by 400 mg once daily for 9 days) and usual care or usual care.
Intervention typeDrug
Pharmaceutical study type(s)
PhasePhase IV
Drug / device / biological / vaccine name(s)Budesonide, baricitinib, imatinib
Primary outcome measure1. For the overall trial (i.e., referred to as stage-2 evaluation of interventions within each trait), the primary endpoint is number of Organ Support Free Days (OSFD) during the first 21 days from randomisation. This will apply to all treatable traits. Where the participant dies within the first 21 days, the OSFD primary endpoint will be assigned a value of minus 1.
2. For the intermediate adaptive analyses (i.e., stage-1 evaluations of interventions within each treatable trait), the intermediate endpoint will be specific for each treatable trait, and therefore highlighted in trait specific protocols.
Secondary outcome measuresSecondary endpoints are those included in the core-outcome set for mechanical ventilation measured using patient records, including:
1. Mortality at different time-points
2. Organ support free days in ICU
3. Days alive outside the hospital (hospital-free days) at 180 days of randomisation
This will apply to all treatable traits.

Additional secondary outcomes may be included in trait-specific protocols.

Target number of participants2,000
Key inclusion criteriaPlatform inclusion
1. Aged ≥18 years
2. Provision of consent (including deferred consent in accordance with Section 5.2)
3. Receiving organ support in a critical care setting
4. Organ dysfunction of at least one organ (SOFA Score>=2)
5. In clinical team’s opinion is likely to require organ support* for ≥24 h post randomisation
6. Resident in Scotland (required for ongoing data linkage)
*Organ support is defined as treatments provided in the critical care units to support one or more of the organ systems, as per the critical care minimum dataset (please see link: https://www.datadictionary.nhs.uk/attributes/organ_system_supported.html). Respiratory support refers to provision of invasive or non-invasive mechanical ventilation, including high-flow nasal cannula with a flow rate ≥30 L per minute and fractional inspired oxygen concentration ≥30%). Cardiovascular support refers to infusion of vasopressor or inotropes. Renal support refers to provision of renal replacement therapy.

Appendix 1: LYMP-RESP TSP inclusion
1. Provision of consent
2. Respiratory dysfunction is defined as PaO2/FiO2 ratio <40 KPa whilst receiving respiratory support with either non-invasive ventilation (including high flow nasal cannula) or invasive mechanical ventilation for 6 hours or longer. Arterial blood gas samples taken within 3 hours of trait eligibility assessment can be used to determine the PaO2/FiO2 criteria.
3. Lymphopenia defined as lymphocyte count <1.2 x 10(9)/L. The lymphocyte count measurements from blood samples done as part of routine clinical care, +/- 36 h of critical care admission could be used. The time window of +/- 36 h reflects the current routine clinical ordering of full blood counts.

Appendix 2: ENDO-SHOCK TSP inclusion
1. Provision of consent
2. Presence of shock: defined as hypotension requiring vasopressor therapy to maintain mean blood pressure 65 mm Hg or greater (equates to cardiovascular SOFA score of 2 or more) and having a blood lactate level greater than 2 mmol/L after adequate initial fluid resuscitation. The term adequate is a clinical judgement. The term initial fluid resuscitation refers to the first set of fluid administration in patients presenting with shock, and acknowledges the fact that resuscitation is an ongoing process. The lactate measurement done as part of routine clinical care using either arterial or venous blood gas, around the time of resuscitation could be used.
3. Evidence of inflammation: defined as C-reactive protein (CRP) 50 mg/L or more OR neutrophil count >=12 x 10(9)/L. The CRP levels and neutrophil count measurements from blood samples done as part of routine clinical care, around the time of trait eligibility assessment (+/- 36 h window) could be used. The time window of +/- 36 h reflects the current routine clinical care.

Any decision to share study data will be discussed and agreed between the study team (grant co-applicants). If sharing of data is deemed appropriate, we will share only anonymised data. The participant information leaflet (PIL) explains to patients that we would like to retain trial data after the trial has ended and so that it can be used in future research studies. Participants have to explicitly agree to this on the consent form (Yes/No) option. If participants do not agree to us retaining their data this will be recorded within the database thereby ensuring their data is removed from any future exports to external research groups.
IPD sharing planThe datasets generated during and/or analysed during the current study are available from the corresponding author on reasonable request from TRAITS@ed.ac.uk
