Lundbeck agreed to acquire the company developing bexicaserin, an investigational treatment for seizures associated with Dravet syndrome and other developmental and epileptic encephalopathies (DEEs). Lundbeck will buy Longboard Pharmaceuticals for $60 a share in cash, or a total of about $2.6 billion, the companies announced. “Bexicaserin…

Longboard Pharmaceuticals has launched a Phase 3 clinical trial evaluating the efficacy and safety of bexicaserin, its investigational treatment for seizures associated with Dravet syndrome and other forms of developmental and epileptic encephalopathies, known as DEEs. The worldwide study, dubbed DEEp SEA, expects to enroll about 160…

The Dravet Syndrome Foundation (DSF) is partnering with the Mason’s Movement Foundation to provide bereavement support to families who have lost someone to Dravet syndrome. The partnership connects bereaved families to a Mason’s Movement initiative called the Good Mourning Project, which provides resources, support, and remembrance items…

The U.S. Food and Drug Administration (FDA) has granted breakthrough therapy designation to Longboard Pharmaceuticals‘ bexicaserin to treat seizures associated with developmental and epileptic encephalopathies (DEEs), including Dravet syndrome, in patients 2 and older. The designation is meant to accelerate the development and regulatory review of medications intended to…

Epidiolex (cannabidiol) can help to reduce seizure frequency in some adults with generalized or localized forms of epilepsy — including Dravet syndrome — that are resistant to other anti-seizures medications, according to a retrospective study in France. Among the 27% of patients who responded to this treatment, most…

Epygenix Therapeutics, the company developing EPX-100 (clemizole) as a potential add-on treatment for people with Dravet syndrome, has been acquired by Harmony Biosciences. “This acquisition builds on our leadership position in sleep/wake and our franchise in neurobehavioral disorders, allowing us to leverage our expertise in CNS…

Brain-like organoids, or “mini-brains,” that are specific to affected brain regions and derived from patients could act as models for studying the underlying molecular mechanisms of Dravet syndrome, a study shows. Researchers created patient-derived organoids of the forebrain, a region enriched with types of nerve cells called GABAergic neurons…
