A Multicenter, Double-blind, Randomized, Parallel-group Evaluation of LAMICTAL Extended-Release Adjunctive Therapy in Patients With Primary Generalized Tonic-Clonic Seizures
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is being conducted to compare the efficacy and safety of LAMICTAL (lamotrigine) extended-release with placebo in the treatment of Primary Generalized Tonic-Clonic (PGTC) seizures. LAMICTAL extended-release is an investigational drug. Placebo tablets look like LAMICTAL extended-release tablets but do not contain active medication.
