  • Total Positive and Negative Syndrome Scale (PANSS) score = 75 at V0
  • Stable antipsychotic treatment dose for at least one week prior to inclusion
  • Stable CNS-active treatment substance and dose (e.g. antidepressants and mood stabilizers) for at least one week prior to inclusion
  • Female participants with reproductive potential must have a negative pregnancy test using a pregnancy test strip as part of the screening visit
  • Female participants with reproductive potential must have a negative serum pregnancy test within seven days prior to randomization
  • Male participants and female participants who are not capable of bearing children or who use a method of contraception that is medically approved by the health authority of the respective country at screening
  • A woman who is not capable of bearing a child is defined as follows: post-menopausal (12 months natural (spontaneous) amenorrhea or 6 months spontaneous amenorrhea with serum-FSH-values (follicle-stimulating hormone) of >40 mIU/mL); 6 weeks after a bilateral ovariectomy with or without hysterectomy or sterilization by means of tubal ligation
  • A woman capable of bearing child is defined as follows: a woman who is physiologically capable of becoming pregnant, including women whose occupation, lifestyle or sexual orientation exclude sexual intercourse with a male partner and women whose partners have been sterilized by vasectomy or other measures.
  • Medically-approved acceptable methods of contraception with a low failure rate (i.e. less than 1% per year) when used consistently and correct can include the following: hormonal contraceptives, intrauterine device and double barrier method. Acceptable preventive measures can include total abstinence at the discretion of the investigator, in cases where compliance is ensured because of the study participant’s age, occupation, lifestyle or sexual orientation. Periodical abstinence (e.g. calendar, ovulation, symptothermal methods or abstinence until the 4th day after the ovulation) as well as coitus interruptus are not acceptable methods of contraception.
  • A reliable method of contraception (CTFG guideline) must be used for the entire duration of the study.
