Efficiency of a Composite Personalised Care on Functional Outcome in Early Psychosis (PSYCARE)

PsyCARE Trial - "Efficiency of a Composite Personalised Care on Functional Outcome in Early Psychosis : A Prospective Randomised Controlled Trial "

Chronic psychosis, including schizophrenia is now viewed as a progressive disorder where cognitive deficits predate the clinical onset. Early intervention programs improve the general outcome with staged care strategies, supporting the view that the period before and around the first episode of psychosis is a window of opportunity for improving its functional recovery. Pioneering epigenetic analyses indicate that psychosis onset involves oxidative stress and inflammation suggesting that neuroprotective strategies could limit or even prevent the onset of or the transition into a chronic disorder. Several biological factors associated with the emergence of psychosis can all be rectified by using safe and easily accepted supplements including alterations folate deficiency/hyperhomocysteinemia; redox imbalance and deficit in polyunsaturated fatty acids (PUFA). The prevalence of these anomalies (20-30%) justifies a systematic detection and could guide personalised add-on strategy. Cognitive remediation improves quality of life (QoL) and functional outcome in patients with chronic psychosis. It would even be more efficacious in the early phase of psychosis by tackling the negative impact of psychosis on education achievement and employment. However, cognitive dysfunctions are often overlooked in patients at ultra-high risk (UHR) for psychosis and patient with a first episode of psychosis (FEP) and cognitive remediation is not always accessible. New technologies can provide us with youth-friendly, non-stigmatising tools, such as applications with cognitive strategies, motivational tools and functioning guidance personalised according to the need of each individual. Patients can have access to it, wherever they live. Early psychosis can be associated with inflammation, metabolic deficiency, as well as early structural brain anomalies that reflect brain plasticity abilities and could influence the prognosis and response to cognitive training. The study hypothesis is that promoting neuroplasticity by cognitive training and personalised virtual psychoeducation guidance could attenuate or reverse early cognitive deficits and improve the overall functional outcome in young patients UHR or FEP and that this effect is modulated by individual brain plasticity abilities. The overall objective of PsyCARE_trial is to improve early intervention in psychosis by providing a composite personalised care (CPC) that will enable personalised cognitive training and psychoeducation guidance, adapted to individuals' needs, cognitive abilities and biological background.

Phase III, Prospective Randomised Open, Blinded End-point (PROBE) controlled trial stratified according to the developmental burden and centre, with 2x2 factorial designs (equivalent to a 4-arms clinical trial) in a 1:1:1:1 ratio.

Cognitive reinforcement using digital applications (PSYCARE application) during 12 weeks +/- virtual reality based cognitive remediation application : 24 sessions over 12 weeks (only for patients who have a higher cognitive deficits (TMTB score >110s))

Personalised neuroprotective medication adapted to the individual's biological profile : Vitamin B12 : 500 micrograms per day Folinic acid : 50 mg per day Omega 3 : 1380 mg EicosaPentaenoic Acid (EPA) + 1140 mg DocosaHexaenoic Acid (DHA) per day N-acetyl-cysteine (NAC) : 2400 mg per day duration of supplementation(s) : 12 weeks

Treatment as usual (TAU), including a standardised psycho-education program with a group cognitive behavioural therapy (e.g. I_Care - You Care) and, in FEP only, second generation antipsychotic from a restricted list (following the recommendations www.orygen.org.au)

Global functioning will be assessed using the Personal and Social Performance Scale (PSP), a well-validated tool for the measurement of social functioning previously used in early psychosis. PSP is a 100-point single-item rating scale (minimum value 1; maximum value: 100). The scale evaluates four main areas: 1) socially useful activities; 2) personal and social relationships; 3) self-care; and 4) disturbing and aggressive behaviours during a determined reference period

Score on the Personal and Social Performance Scale (PSP) PSP is a 100-point single-item rating scale (minimum value 1; maximum value: 100). The scale evaluates four main areas: 1) socially useful activities; 2) personal and social relationships; 3) self-care; and 4) disturbing and aggressive behaviours during a determined reference period

Scores at Global Functioning Scale-Social and Role [120], measured at V2 and V3. This scale provides a 1 to 10 score separately for social role and for functioning.

Comprehensive Assessment of At Risk Mental State (CAARMS) CAARMS evaluates seven dimensions of symptomatology. It provides operational criteria to categorise subjects as 'at-risk' or as psychotic (psychosis threshold) on the basis of the first subscale (10 min), 'positive symptoms' encompassing four sub-scales (Unusual Thought Content, Non-Bizarre Ideas, Perceptual Abnormalities, Disorganised Speech)

- SOFAS (Social and Occupational Functioning Assessment Scale or EFSP. SOFAS specifically estimates social functioning on a scale between 0 and 100.

- MADRS (Montgomery-Asberg depression scale). MADRS is a 10 -item scale that evaluates different aspects of depressive symptomatology. It provides a good estimation of the severity of depression and is sensitive to change.

- Brief Psychiatric Rating Scale (BPRS). BPRS is a scale that evaluates general psychiatric symptomatology.

PANSS (Positive and Negative Syndrome Scale) PANSS is a 30-item scale widely used in schizophrenia research to assess positive and negative psychotic dimensions as well as general symptomatology

Clinical Global Impression (CGI) scale. CGI estimates the current severity, of illness on a 7-point scale, as well as evolution and therapeutic index in reference to the clinicians past experiences of similar patients (3 items).

The recording of the interview will allow to extract reliable linguistic metrics that will be processed semi-automatically.

Neurological Soft Signs rating scale (NSS) assesses five factors: motor coordination, motor integration, sensory integration, quality of lateralization and involuntary movements or posture; as well as extrapyramidal symptoms (Simpson Angus Scale) and lateralization (Edinburgh questionnaire).

Electronic Neurological Soft Signs (eNNS) This device incorporates a new, tablet-based and clinically suitable app (behavioral tasks), including tasks designed to probe balance of excitation/inhibition (multi-finger tapping task), body scheme tasks where finger posture recognition is measured and visuomotor sequence learning under variable cognitive load (using visual attentional distractors).

Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS) is a 21-item Likert-type scale that allows a quantitative approach of cognitive complaint.

Embodiment ability in virtual reality environment will be assessed using a simulation of two districts of a lively city via the Vive Pro virtual reality kit

Short Form -12 items quality of life questionnaire (SF-12) SF-12 is a multipurpose self-report measure of both physical and mental health status

European Quality of Life - 5 Dimensions - 5 Levels (EQ-5D-5L) EQ-5D-5L investigates 5 dimensions: mobility, self care, usual activities, pain/discomfort, anxiety/depression. These 5 dimensions are rated on 5 levels ranging from no problems to extreme problems.

Levels of RNA (messenger RNA, microRNA, long non-coding RNA) will be assessed using next generation sequencing methods.

Levels of RNA (messenger RNA, microRNA, long non-coding RNA) will be assessed using next generation sequencing methods.

Incremental cost-effectiveness ratios (ICER) will assess the efficiency of CPC vs. TAU (overall and by component). They will be expressed in cost per quality-adjusted life-years (QALY) gained and in cost per PSP point gained.

Total costs and health benefits associated with generalizing CPC will be assessed and compared to TAU over a 5-year period.
