E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the long-term safety of 1 and 2 mg doses of EVP-6124 tablets administered once daily for up to 52 weeks in subjects who received EVP-6124 in both the pivotal and extension studies and up to 26 weeks in subjects who were randomized from placebo to EVP-6124 upon entry into this extension study. |
|
E.2.2 | Secondary objectives of the trial |
To assess the extended clinical effects of 1 and 2 mg doses of EVP-6124 tablets administered once daily for up to 26 weeks. Clinical effects assessments will include Clinical Global Impression (CGI) – Severity (CGI-S) and Change (CGI-C) scales, quality of life using the EuroQol-5D™ (EQ-5D-5L), and healthcare resource utilization using the Client Socio-Demographic and Service Receipt Inventory-European Version (CSSRIEU). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Completion of the Day 182 visit in a previous 26-week double-blind study (EVP-6124-015 or EVP-6124-016). 2. Subject has signed informed consent for this extension study, indicating that the subject understands the purpose of and procedures required for the study, before the initiation of any extension study specific procedures. Subjects who are unable to provide informed consent will not be included in the study. 3. No clinically significant changes in the subject's medical status during participation in EVP-6124-015 or EVP-6124-016. Any significant changes in health care status and their impact on subject eligibility will be reviewed by the investigator and sponsor on a case-by-case basis. 4. In the opinion of the investigator, the extension treatment is in the best interest of the subject. 5. Fertile, sexually active subjects (men and women) must use an effective method of contraception during the study. Females and the female partners of males must be surgically sterile (hysterectomy or bilateral tubal ligation), postmenopausal for at least 1 year, or willing to practice adequate methods of contraception if of childbearing potential (defined as consistent use of combined effective methods of contraception [including at least one barrier method]). Female subjects must have a negative urine pregnancy test predose on Day 1. |
|
E.4 | Principal exclusion criteria |
1. Significant risk for suicidal or violent behavior, as determined by the investigator. Significant risk for suicidal behavior is defined as 1) suicidal ideation as endorsed on items 4 and 5 of the C-SSRS; 2) suicidal behaviors detected by the C-SSRS; or 3) psychiatric interview and examination. 2. Adverse events from the previous study (EVP-6124-015 or EVP-6124-016) that have not resolved, are of moderate or greater severity, and judged to be possibly related or related to study drug and are thought by the investigator to be contraindications to study participation. 3. Any condition which would make the subject, in the opinion of the investigator, unsuitable for the study. 4. Female subjects who are pregnant. 5. Subjects who received any other investigational treatment during participation in either EVP-6124-015 or EVP-6124-016 other than assigned study medication. |

E.5 End points |
E.5.1 | Primary end point(s) |
The safety analysis is intended to describe the safety and tolerability of each dose of EVP-6124 (1 and 2 mg). The assessment of safety will be based primarily on the following assessments: AEs, clinical laboratory tests, vital signs measurements, ECGs, SAS, CDSS, C-SSRS, and directed physical examinations. All safety data will be analyzed descriptively. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Clinical efficacy will be evaluated by the CGI-S, CGI-C, EQ-5D and the CSSRI-EU. Descriptive statistics to assess the change from baseline will be provided for each clinical effects variable by dose group and overall at each visit. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
All efficacy assessments will be performed on one or more of the following study visits Days 1, 56, 112, and 182/ET. |
