E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to investigate the efficacy, safety and tolerability of BI 409306 compared to placebo given for 52 weeks to patients with attenuated psychosis syndrome. The study is designed to show superiority of BI 409306 over placebo in achieving remission of APS as well as improvement in cognition and functional capacity. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Biomarker sub-study: EEG, Version 1.0 dated 31-Jan-2017
Resting state EEG, auditory and visual ERP measurements will be explored and evaluated at the baseline Visit 2 (pre-dose) and Visit 23 (EOT) from a subset of the main study patient population.
The objective of this sub-study is to measure and analyse the change of neurophysiological functions of the brain from baseline to the end of treatment in a subset of patients from the main study which is in patients with attenuated psychosis syndrome who are treated with BI 409306 50 mg b.i.d. or placebo over a treatment period of 52 weeks. The study will investigate the clinical utility of resting qEEG/ERP/auditory and visual ERP
biomarkers for risk stratification and targeted intervention. The evaluation of EEG data will be exploratory in nature and will provide further insights on the methodologies themselves, neurophysiological changes in patients with attenuated psychosis syndrome, and the potential effect of the treatment on these measurements.
Ocular Safety Substudy, Version 4.0 dated 04- Oct-2018
A subset of patients from the main study will complete ocular safety tests to further characterise the ocular safety of BI 409306. Best Corrected Visual Acuity and colour vision wil be evaluated at the baseline Vist 2 ( pre-dose), 24 weeks and 52 weeks or EOT. Ocular safety wil be assessed in a descriptive way based on chnage from baselines for the following endpoints:
-Best Corrected Visual Acuity test (BCVA) determined using a Snellan Chart
-Total erorr score from the Farnsworth- Munsel 100 hue testing (F-M 100) |
|
E.3 | Principal inclusion criteria |
1. Meet diagnostic criteria for attenuated psychosis syndrome as defined in DSM-5 and determined by SIPS administered at screening, and diagnosis confirmed by Central Rating Committee after review of video-taped SIPS interview.
2. Inclusion criterion 2 removed in global amendment 3. Numbering of subsquent criteria not changed.
3.Age ≥16 and ≤ 30 years at the time of consent/assent.
4. Male or female patients willing to use highly effective methods of contraception.
- Female patients of childbearing potential1 must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. Patients must agree to use birth control throughout the trial and for at least 28 days after treatment has ended. Acceptable methods of birth control include combined estrogen-progestin oral, intravaginal or transdermal contraceptives, progestogen-only oral, injectable or implantable contraceptives, intrauterine devices (IUDs), intrauterine hormone releasing systems (IUSs), bilateral tubal occlusion, vasectomized sexual partner, and complete sexual abstinence (if acceptable by local health authorities) is allowed when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptom-thermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
- Male patients who are able to father a child must be ready and able to be abstinent or use adequate contraception for the duration of study participation and for at least 28 days after treatment has ended.
5. Signed and dated written informed consent in accordance with Good Clinical
Practice (GCP) and local legislation prior to any study-related procedures OR
signed and dated informed consent provided by the patient’s parent(s) (or legal
guardian) and assent by the patient prior to any study-related procedures in
accordance with GCP and local legislation2. If the patient has a legal
representative, then this legal representative must give written informed consent
as well. |
|
E.4 | Principal exclusion criteria |
1. Present or past diagnosis of schizophrenia, schizophreniform, schizoaffective disorder, bipolar disorder I, or major depressive disorder with psychotic symptoms according to DSM-5.
2. Patients taking antipsychotic medication for less than 8 weeks, or patients taking antipsychotic medication for a longer duration but who have not been on a stable dose fro 8 weeks prior to informed consent.

4. Patients who have discontinued an antipsychotic medication less than two weeks prior to randomization.
5. Patients taking Clozapine.
6. Suicidal behavior in the past 2 years reported in the Columbia Suicide Severity Rating sacele ( C-SSRS) with a lethality of attempt of ≥1 , or with a lethality of 0 but a potential lethality of 2, or that in the judgement of the investigator would jeopardise the patient's safety while participating in the trial. The investigator/qualified rater must review all screening C-SSRS reports prior to randomisation, documenting an additional interivew asessing lethality of the behaviour history when appropriate.
7. Any suicidal ideation of type 4 or 5 in the Columbia Suicide Severity Rating Scale (CSSRS) in the past 3 months (i.e. active suicidal thought with intent but without specific plan, or active suicidal thought with plan and intent).
8. In the judgment of the investigator, any clinically significant finding from the physical examination or laboratory value deviating from normal or any evidence of a clinically significant concomitant disease or any other clinical condition that would jeopardize a patient’s safety while participating in the clinical trial.
9. Known diseases of the central nervous system (including but not limited to any kind of seizures or stroke).
10. History of significant head injury (>5minute without consciousness).
11. A serious developmental disorder that in the judgement of the investigator would inhibit the patient's ability to comply with all study procedures, or mental retardation (documented IQ <70), or acute attenuated symptoms exclusively related to intoxication from a psychotropic substance.
12. Any documented active or suspected malignancy or history of malignancy within 5 years prior to screening, except appropriately treated basal cell carcinoma of the skin or in situ carcinoma of uterine cervix.
13. Planned elective surgery requiring general anesthesia, or hospitalization for more than 1 day during the study period.

Patients taking medication known to be strong or moderate inhibitors of CYP1A2 must be prospectively genotyped to ensure they are not poor metabolizers of CYP2C19. (A list of CYP1A2 and CYP2C19 inhibitors can be found in the ISF.).
17. Patients taking strong or moderate CYP1A2 inhibitors who are also taking concomitant strong or moderate CYP2C19 inhibitors. (A list of CYP1A2 and CYP2C19 inhibitors can be found in the ISF.)

|
E.5.2 | Secondary end point(s) |
