E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary Objectives The primary objective is to investigate the safety and tolerability of JNJ-37822681 administered as qd or bid following a dose titration in male and female patients with stable schizophrenia. |
|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives The secondary objectives of this study include: • To investigate the plasma pharmacokinetic (PK) profile of JNJ-37822681 administered as once daily (qd) or twice daily (bid) in male and female patients with stable schizophrenia; • To investigate the effect of JNJ-37822681 on plasma prolactin (PRL) levels. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study • Male or female between 20 and 55 years of age, inclusive • Female subjects must meet one of the following: – postmenopauzal (amenorrhoea for at least 12 months and FSH levels of >40 MIU/mL at screening), – surgically sterile, (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy) • Men participating in this study have to use a condom at each sexual intercourse even when their partner is pregnant. They should not father a child and not donate sperm during the study and for 3 months after receiving the last dose of study drug. For men that have been clinically determined to be vasectomized, this restriction applies for 5 days after receiving the last dose of study drug. Also their female partner should use an effective method of contraception above the condom used by the male study subject. (Effective methods of contraception include prescription oral contraceptives, contraceptive injections, intrauterine device, doublebarrier method, contraceptive patch). • In- or outpatients with schizophrenia stably treated for at least 6 months with antipsychotic monotherapy (≤ 200mg/d chlorpromazine equivalent dose) or stable for at least 3 months without drug therapy; patients who receive a second antipsychotic at doses < recommended for antipsychotic efficacy may participate provided the second antipsychotic will be discontinued at least 2 weeks prior to first dose administration. PANSS at screening < 70 • DSM-IV criteria for Schizophrenia • In the opinion of the investigator and in compliance with local regulations, the subject can be withdrawn from current antipsychotic medication. • A known history of schizophrenia of at least 12 months by the referring psychiatrist. • Body Mass Index (BMI) between 18 and 35 kg/m2 inclusive (BMI = weight/height2) • Willing to be hospitalized during the double-blind treatment period of the study. • Willing to adhere to the prohibitions and restrictions specified in this protocol. |
|
E.4 | Principal exclusion criteria |
• A DSM-IV axis I diagnosis other than schizophrenia • A DSM-IV diagnosis of substance dependence within 6 months prior to screening evaluation (nicotine and caffeine dependence are not exclusionary; patients with a positive drug screen at screening may be included provided use does not lead to a DSM-IV diagnosis of substance dependence and patients consent to abstain from alcohol and illegal drugs within 3 days prior to Day –1 and at any time during the study) • Any medical condition that could potentially alter the absorption, metabolism, or excretion of the study medication, such as Crohn’s disease, liver disease, or renal disease • Relevant history of any significant and/or unstable cardiovascular, respiratory, neurologic (including seizures or significant cerebrovascular), renal, hepatic, endocrine, or immunologic diseases • History of neuroleptic malignant syndrome (NMS) • Other significant and/or unstable systemic illnesses • Allergy or hypersensitivity to any known antipsychotic compounds • Inability to swallow the study medication whole with the aid of water (subjects may not chew, divide, dissolve, or crush the study medication, as this may affect the release profile) • Exposure to an experimental drug or experimental medical device within 90 days before screening • Significant risk of suicidal or violent behavior • Female subjects of childbearing potential • Female subjects who are pregnant or breastfeeding • Alanine aminotransferase or aspartate aminotransferase levels more than 2 times the upper limit of normal at screening or baseline • Other biochemistry, hematology, or urinalysis results that are not within the laboratory’s reference range, and that are deemed by the investigator to be clinically significant • Use of beta-blockers (if used for any indication other than hypertension and still present at baseline) • Injection of a depot antipsychotic within 120 days before screening, or use of paliperidone palmitate within 10 months before screening • Use of fluoxetine or monoamine oxidase inhibitors within 4 weeks before screening • Use of all other antidepressants, anticonvulsants, or lithium within 2 weeks before baseline • Received electroconvulsive therapy within 3 months before screening • Have been involuntarily committed to psychiatric hospitalization • Donation of 1 or more units (approximately 450 mL) of blood or acute loss of an equivalent amount of blood within 90 days prior to study drug administration. • Any condition that, in the opinion of the investigator, would compromise the well-being of the subject or the study • Employees of the investigator or study center, with direct involvement in the proposed study or other studies under the direction of that investigator or study center, as well as family members of the employees or the investigator. |
