Why Slenyto® ?

Slenyto® Clinical Evidence

Slenyto® efficacy was demonstrated in a randomized placebo-controlled, multi-center confirmatory, Phase III trial conducted in 4 countries including 125 pediatric ASD and SMS patients. Patients were aged 2-18 year old and were treated with either Slenyto® (60 patients) or placebo (65 patients) for a period of 13 weeks, followed by a long term follow up (91 weeks) in which all patients were treated with Slenyto® (total of 2 years) with additional 2 weeks placebo run-out period.

28.8% of participants had comorbid ADHD, and 12.8% participants had comorbid epilepsy. Prior ADHD treatment was reported by 10.4% of the participants, antidepressant by 8%, anti-epileptics by 6.4%, clonidine by 5.6%, and β-blockers by 0.8%.

The study was successfully completed demonstrating Slenyto® efficacy in improving children sleep variables (sleep onset, maintenance and total sleep time), children daytime behavior and parents well-being , both in the short- and long-term, demonstrating Slenyto® ability to provide patients with Good Nights and Better Days.
