Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Treatment-emergent Adverse Events	Treatment-emergent adverse events (TEAEs) are defined as adverse events (AEs) which started on or after the date of the first LCIG Infusion in this study and within 30 days of the date of the last PEG-J exposure.; At least possibly drug-related is defined as TEAEs assessed as having a "Possible" or "Probable" or missing relationship to study drug.; Serious AEs included any untoward medical occurrence that: Resulted in death; Was life-threatening; Required inpatient hospitalization or prolongation of an existing hospitalization; Resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect; The severity of all AEs was characterized as mild, moderate or severe according to the following definitions: Mild: usually transient and do not interfere with daily activities.; Moderate: low level of inconvenience or concern to the subject, may interfere with daily activities.; Severe: events interrupt the subject's usual daily activity.	From first dose of LCIG in this study up to 30 days after the date of last PEG-J exposure; median duration of treatment was 1178 days, with a maximum of 4217 days (11.5 years).
Secondary	Number of Participants With Device Complications	Device complications include complications with the pump, intestinal tube, PEG-J or stoma.	From first dose of LCIG in this study up to 30 days after the date of last PEG-J exposure; median duration of treatment was 1178 days.
Secondary	Number of Participants With Sleep Attacks	Participants were asked whether they experienced any events in which they fell asleep suddenly or unexpectedly, including while engaged in some activity (e.g., eating/drinking, speaking, or driving) or at rest, with or without any previous warning of sleepiness. If yes, participants were asked if they suffered any "bad" outcome or problem from the falling asleep event.	Baseline (final assessment period of the previous open-label LCIG study) and every 6 months until final visit; median duration of treatment was 1178 days.
Secondary	Number of Participants With Intense Impulsive Behavior	To monitor for the development of intense impulsive behavior the Minnesota Impulsive Disorder Interview (MIDI) was administered.

Secondary	Number of Participants With Any Suicidal Ideation or Behavior	The Columbia-Suicide Severity Rating Scale (C-SSRS) was implemented with Protocol Amendment 3 (20 March 2012) in order to assess suicidal behavior and ideation.; Suicidal ideation includes the wish to be dead, nonspecific active suicidal thoughts, active ideation without intent to act, active ideation with some intent to act, and active ideation with specific plan or intent. Suicidal behavior includes actual attempts, interrupted attempts, aborted attempts, completed suicide, and preparatory acts or behaviors.; The number of participants with affirmative responses on the C-SSRS at any time during the treatment period is reported.	Every 6 months (beginning with implementation of Protocol Amendment 3) until final visit; median duration of treatment was 1178 days.
Secondary	Number of Participants With Potentially Clinically Significant Vital Sign Values	A vital sign value was considered potentially clinically significant if it satisfied the pre-specified criteria presented in the table and was also more extreme than the participant's corresponding Baseline value.	Baseline and every 6 months until final visit; median duration of treatment was 1178 days.
Secondary	Number of Participants With Potentially Clinically Significant Hematology Laboratory Values	A laboratory value was considered potentially clinically significant if it satisfied the pre-specified criteria presented in the table and was also more extreme than the participant's corresponding Baseline value.
