An Open-Label Extension Study Of Lamotrigine In Subjects With Bipolar Disorder
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The precursor study (SCA101469) was an open-label, prospective multicentre study in adult subjects diagnosed with bipolar disorder consisting of 36 weeks treatment with lamotrigine. The current study is to provide 12 months post study access to open-label lamotrigine for participants of the SCA101469 study.
Number of Participants With Serious Adverse Events (SAEs) [ Time Frame: Up to 54 weeks ]
An adverse event (AE) is defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event is therefore any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. An SAE is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect. Only SAEs were recorded and reported in this extension study.
