The DEEp OCEAN Study

A New Wave of Hope

The DEEp OCEAN clinical study is assessing the safety of the investigational drug, bexicaserin, and its potential to reduce the number of seizures in children and adults with DEE.

Eligible participants include individuals aged 2 to 65 who have been diagnosed with Developmental and Epileptic Encephalopathies (DEE) and have experienced the onset of seizures from birth to 8 years of age for people with Lennox-Gastaut Syndrome (LGS) or birth to 5 years old for people with DEE (other). Additionally, they have experienced an average of four seizures per month over the past three months.
