complied with the inclusion and exclusion criteria for that study (excluding criteria
that are related to seizure occurrences).

2. Provided written informed consent signed by participant or legal guardian prior to

was provided by the legal guardian because the participant was unable to do so, a
written or verbal assent from the participant was obtained).

3. Who was considered reliable and willing to be available for the study period and
record seizures and report adverse events them self or have a caregiver who can record
and report the events for them.

4. Females who were either of non-childbearing potential (defined as having undergone
surgical sterilization, or postmenopausal [>age 50 and amenorrheic for 12 months]) or

diaphragm with spermicide], IUD, or have a vasectomised partner) throughout the study
period and for 2 months after the last dose of study drug. Women using hormonal
contraceptives were required to use an additional approved method of contraception (as
described previously) continuously throughout the entire study period and for 2 months
after the last dose of study drug. (It was not required for male subjects to use
contraceptive measures based on preclinical toxicology data).

5. Continued to be treated with a stable dose of 1 or a maximum of 3 approved
