About this study
Official title: Real-world Effectiveness and Safety of Antipsychotics in Individuals at Clinical High-risk for Psychosis: Study Protocol for a Prospective Observational Study (SHARP-2)
The current study will improve knowledge on the effectiveness and safety of the use of antipsychotics at the prodromal phase and on factors influencing the outcome, and will eventually facilitate optimisation of individualised interventions for psychosis prevention and treatment.
Read the detailed description
Help-seeking first-visit participants will be consecutively recruited. Every participant meeting the inclusion criteria will be fully informed of the study and asked to sign the written informed consent before enrolment.
Two senior nurses that will conduct the initial screenings were employed to collect all diagnostic and medication information from medical records on every follow-up visit. The four psychiatrists are qualified and well-trained and will conduct the SIPS/SOPS interview at baseline and follow-up.
The investigators will systematically record medication information. A model will be established to correlate antipsychotics with clinical and functional outcomes and demonstrate whether antipsychotics are useful and safe for preventing CHR individuals from converting to psychosis.
Based on experience from the sampling process in the SHARP-1 project, the investigators will recruit 600 participants at CHR. Considering a dropout rate of 20%, 510 cases of CHR will be followed up. According to the sample size calculation formula in superiority clinical trials of new drugs, the sample size of 600 cases is adequate for the demonstration of the effectiveness and safety of antipsychotics in CHR subjects.

What is being measured
The primary outcome is the main question the study is designed to answer.
Conversion to psychosis
It will be determined using the criteria for the Presence of Psychotic Symptoms from SIPS. Specifically, the conversion will be defined by the presence of level 6 positive symptoms (the rating "6" refers to severe and psychotic symptoms) identified as either dangerous, disorganised, or occurring at least one hour a day on average, over four days a week for at least 16 hours.
Measured: 4 weeks
Poor function
It will be determined by GAF score. Specifically, poor function outcome is defined as the GAF score of less than 60 at the follow-up point.
Measured: 4 weeks

Detailed description
Help-seeking first-visit participants will be consecutively recruited. Every participant meeting the inclusion criteria will be fully informed of the study and asked to sign the written informed consent before enrolment.
Two senior nurses that will conduct the initial screenings were employed to collect all diagnostic and medication information from medical records on every follow-up visit. The four psychiatrists are qualified and well-trained and will conduct the SIPS/SOPS interview at baseline and follow-up.
The investigators will systematically record medication information. A model will be established to correlate antipsychotics with clinical and functional outcomes and demonstrate whether antipsychotics are useful and safe for preventing CHR individuals from converting to psychosis.

Questions about this trial
What is this clinical trial studying?
An observational study of Clinical High-risk, run by Shanghai Mental Health Center at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 22 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact TianHong Zhang, Doctor (13127577024, zhang_tianhong@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Conversion to psychosis (time frame: 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04010864, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
