Details and patient eligibility

About

Assessment of long-term safety and efficacy of oral lacosamide (LCM) as an adjunctive therapy for uncontrolled primary generalized tonic-clonic seizures (PGTCS) in subjects >= 4 years of age with idiopathic generalized epilepsy (IGE). This study will enroll subjects from the LCM SP0982 [NCT02408523] study.

Enrollment: 239 patients

Sex: All

Ages: 4+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Subject must have completed or be an eligible Baseline failure from the parent study (SP0982 [NCT02408523]). Note: Other subjects screened for SP0982 may be considered for roll-over to EP0012 if the investigator considers that the subject could benefit from treatment with open-label lacosamide (LCM) and based on prior discussion with and approval from the UCB Study Physician or representative

Exclusion criteria

• Subject is receiving any investigational drugs or using any experimental devices in addition to lacosamide (LCM)
• Subject meets the withdrawal criteria for SP0982 or is experiencing an ongoing serious adverse event (SAE)
• Subject has an active suicidal ideation as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the "Since Last Visit" version of the Columbia-Suicide Severity Rating Scale (C-SSRS)
• Subject has >=2x upper limit of normal (ULN) of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or >ULN total bilirubin (≥1.5xULN total bilirubin if known Gilbert's syndrome). If subject has elevations only in total bilirubin that are >ULN and <1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin <35%). For all subjects who entered EP0012 directly with a Baseline result >ULN for ALT, AST, ALP, or total bilirubin, a Baseline diagnosis and/or the cause of any clinically meaningful elevation must be understood and recorded in the electronic Case Report form (eCRF). Tests that result in ALT, AST, or ALP up to 25% above the exclusion limit may be repeated once for confirmation.
