E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
E2007 is given as adjunctive, long-term treatment in patients with refractory partial onset seizures with or without secondary generalization |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective for this study is to evaluate the safety of E2007 given as adjunctive, long-term treatment in patients with refractory partial onset seizures with or without secondary generalization that completed the E2007-A001-206 or the E2007-G000-208 study. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective for this study is to evaluate the long-term maintenance of E2007 efficacy for the control of partial onset seizures by the change in partial seizure frequency from Baseline in the E2007-A001-206 or E2007-G000-208 studies to the OLE Maintenance Phase (revised per Amendments 02 and 04). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Provide written informed consent signed by the patient or legal guardian prior to entering the OLE study or undergoing any study procedures.
2. Have completed all scheduled visits up to and including Visit 8 in the E2007-A001-206 study or Visit 9 of the E2007-G000-208 study (revised per Amendment 04).
3. Are reliable and willing to make themselves available for the study period and are able to record seizures and report adverse events themselves or have a caregiver who can record and report the events.
4. Male and female patients will be eligible for enrollment. Females of childbearing potential must continue practicing a medically acceptable method of contraception (eg, abstinence, a barrier method plus spermicide, or IUD) and for two months after the end of the OLE study. Those women using hormonal contraceptives must also continue using an additional approved method of contraception (eg, a barrier method plus spermicide, or IUD) starting with the Titration Phase and continuing throughout the entire study period (revised per Amendment 02).
5. Are between the ages of 18 and 70 years of age, inclusive.
6. Are at least 40 kg (88 lb) of weight.
7. Are currently being treated with a stable dose of one, or a maximum of three, marketed and approved AEDs and are known to take their medication(s) as directed (revised per Amendment 04).
|
|
E.4 | Principal exclusion criteria |
1. Show evidence of clinically significant disease (cardiac, respiratory, gastrointestinal, renal disease, etc.) that in the opinion of the Investigator(s) could affect the patient’s safety or trial conduct.
2. Show evidence of significant active hepatic disease and/or bilirubin > 1.5 mg/dL. Stable elevations of liver enzymes, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) due to concomitant medication(s) will be allowed if they are less than two times the upper limit of normal (ULN).
3. Show evidence of significant active hematological disease. White blood cell (WBC) count cannot be <= 2500/microliter (2.50 1E+09/L) or an absolute neutrophil count <= 1000/microliter (1.00 1E+09/L) (revised per Amendment 01).
4. Clinically significant ECG abnormality, including prolonged QTc (defined as >= 450 msec). (revised per Amendments 03 and 04).
5. Presence of major active psychiatric disease. Patients taking a stable dose of selective serotonin reuptake inhibitor (SSRI) antidepressant will be allowed (revised per Amendment 03).

E.5 End points |
E.5.1 | Primary end point(s) |
Safety of open-label study population exposed to E2007 in partial epilepsy patients with refractory seizures with or without secondary generalization will be examined based on nature, frequency, and severity of adverse events, vital signs, physical and neurological examination findings, 12-lead ECG abnormalities and chemistry and hematology laboratory test results. |
