2 Clinical Trials for Various Conditions
The purpose of this study is to assess the safety and feasibility of Magnetic Resonance Imaging-guided focused ultrasound (MRgFUS) in patients with epilepsy whose medicines are not working well. The ExAblate (ExAblate) transcranial system is the name of the device that will be used to create and send ultrasound waves through the scalp and skull precisely to a small structure located in the center of the brain. This structure is known as the "Anterior Nucleus", and is an important region in the brain that may cause the seizures. Safety will be measured by recording and analyzing any adverse effects that may occur from the day of the experimental surgery through 12 months following the surgery.
Subjects enrolled in the SP615, SP756, or SP774 open-label extension (OLE) trials receiving oral SPM 927 for at least 8 weeks and a stable dose of up to 3 antiepileptic medications may participate in a research trial at approximately 30 locations. Trial objectives include investigating whether iv SPM 927 is safe and well tolerated when given twice daily for a short period of time and identifying the appropriate infusion rate(s). Subjects will receive SPM 927 as a 30-, 15- or 10- minute infusions twice daily for 2 - 5 days based on notification by the research doctor and subject choice. Subjects will remain on the same stable dose as received in the OLE trial. Trial procedures will include medical history update, physical/ neurological exams, ECGs, blood /urine sample collections and seizure diary completion. Subjects completing the trial will return to the OLE trial to resume dosing with oral SPM 927.
