INSYS Therapeutics Initiates Phase 3 Clinical Trial of Cannabidiol (CBD) Oral Solution for Treatment of Infantile Spasms

PHOENIX, March 02, 2018 -- INSYS Therapeutics, Inc. (NASDAQ:INSY), a leader in the development, manufacture and commercialization of pharmaceutical cannabinoids and spray technology, today announced the initiation of a Phase 3 clinical trial to study cannabidiol (CBD) oral solution for the treatment of infantile spasms, a rare type of pediatric epilepsy that occurs in very young children, with the first trial site’s activation.

“We need better treatments for infantile spasms, one of the more severe and dangerous seizure disorders of early childhood,” said Shaun Hussain, M.D., a pediatric neurologist at UCLA Mattel Children’s Hospital and director of its Infantile Spasms Project. “That’s why we’re excited about this pivotal study, which has the potential to reveal a new piece of the treatment puzzle for infantile spasms.”

In previous studies, CBD—one of the main molecules in cannabis—has demonstrated sustained clinical benefits in a variety of medically refractory pediatric epilepsies, including infantile spasms, an uncommon condition estimated by the Child Neurology Foundation (CNF) to be diagnosed in about 1,200 children in the United States each year.

“We have great hope in the potential of our proprietary formulation of pharmaceutical-grade, synthetically manufactured CBD oral solution in combination with vigabatrin to offer greater seizure control to children with infantile spasms,” said Steve Sherman, senior vice president of regulatory affairs for INSYS Therapeutics. “The need for more efficacious and better tolerated products to treat this devastating disorder continues to motivate us to advance this investigational therapy through the clinical and regulatory pathway.”

According to the Infantile Spasms Action Network (ISAN), a collaborative advocacy network of 25 national and international organizations convened by CNF, infantile spasms have an average age of onset of around four months, although in some cases the first seizure occurs as early as one month or as late as two years. In most cases, infantile spasms appear to be slight head drops, which belie the seriousness of the condition. Evidence shows that infantile spasms are a more serious seizure disorder than generalized convulsions.

INSYS Therapeutics recently became a member of ISAN, which hosts an annual awareness and education initiative, Infantile Spasms Awareness Week (ISAW), held Dec. 1–7.
