Patientheque in Patients With a Psychosis (LONGIPEP)

June 24, 2026 updated by: University Hospital, Brest

Formation of a Patientheque in Patients With a Beginner Psychosis

Establishment of a patient library for patients who have had a first psychotic episode and who have an "at risk" status for psychotic disorder (GRD, APS, BLIPS group) or a psychosis threshold during CAARMS administration. Samples are taken on inclusion, at 2 years, and if relapse or significant clinical event within 5 years of inclusion, on 250 patients for 10 years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The constitution of this patient library will include results of clinical tests carried out in current practice, neurocognitive tests, blood samples, audio recordings, clinical follow-up, urine samples, fecal samples, brain imaging, EEG.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
250

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

15 years to 30 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Major and or minor aged 15 to 30 assessed within the CEVUP (Consultation for the Assessment of Psychological Vulnerability) and cared for at the psychiatry center as part of a first psychotic episode (Diagnosis CIM 10: F20 -F29 first hospitalization). These patients are referred by care and medico-social partners (general practitioners, school doctors, school nurses, educators, addictologists, psychiatrists
  • "At risk" status for psychotic disorder (GRD, APS, BLIPS group) or psychosis threshold during the CAARMS test (psychometric scale for the assessment of psychotic symptoms)
  • Consent of the patient or his legal guardian

Exclusion Criteria:

  • History of psychosis for more than one year
  • "Not at risk" status for psychotic disorder on the CAARMS (psychometric scale for the assessment of psychotic symptomatology)
  • IQ<70 (WAIS)
  • Neurological disorder or other health problem that may explain the disorders
  • Refusal to participate - History of psychosis for more than one year

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Patient library
All the patients are included in one arm. They will undergo various type of samples.
Other: Blood samples (36 mL) + fecal samples + hair sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
CAARMS (Comprehensive assessment of at-risk mental states) score.
Time Frame: 5 years

The test will determine the mental state of the patient :

  • "Not at risk of psychosis"
  • "At risk of psychosis"
  • "Psychosis threshold exceeded"

It is organized into 7 clinical dimensions: 1) positive symptoms 2) cognitive changes: attention / concentration 3) emotional disturbance 4) negative symptoms 5) behavioral change 6) physical and motor changes 7) general psychopathology.

Each category is scored between 0 and 6 depending on the level of intensity, frequency and duration of each symptom.

In order to determine if a subject meets the UHR criteria for CAARMS, only the first category (positive symptoms) and its four subscales are used according to a scoring algorithm.
5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
CAARMS sub-assemblies
Time Frame: 5 years
If the patient is classified at risk of psychosis, the test will classify this risk into one of the three following categories : trait and state risk factor group, APS (attenuated psychotic symptoms) group, BLIPS (Brief, Limited or Intermittent Psychotic Symptoms) group.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
