-- Continued Improvements in RSBQ and CGI-I scores seen with long-term DAYBUE treatment in Phase 3 LAVENDER™ and LILAC studies
-- DAYBUE safety profile was consistent with findings from the LAVENDER trial
Acadia Pharmaceuticals Inc. (Nasdaq: ACAD) today announced that the journal Med published results from two open-label extension studies, LILAC-1™ and LILAC-2™, which showed that patients treated with DAYBUE™ who completed these studies experienced improvement in Rett symptoms as measured by the Rett Syndrome Behaviour Questionnaire (RSBQ). LILAC-1 was a 40-week, open-label extension study of the 12-week Phase 3 LAVENDER™ trial, evaluating the long-term safety and efficacy of DAYBUE in patients with Rett syndrome five to 21 years of age. LILAC-2 was a 32-month open-label extension study, evaluating the long-term safety and efficacy of DAYBUE in females aged five to 22 years who completed LILAC-1. The most common side effects reported in these studies were diarrhea and vomiting. Results from both studies also showed DAYBUE’s safety profile was consistent with results from the LAVENDER trial.
“These data from the open-label extension LILAC studies provide deeper insight into the long-term safety and potential benefit of DAYBUE for patients with Rett syndrome,” said Alan Percy, M.D., Professor of Pediatrics, Neurology, Neurobiology, Genetics, and Psychology at University of Alabama, Birmingham and lead author for the LILAC-1 and LILAC-2 studies. “These publications add to the growing body of research on clinical experience with DAYBUE and its potential ongoing impact for those living with this condition.”
“These findings from LILAC-1 and LILAC-2 add to the results from the pivotal Phase 3 LAVENDER trial and the ongoing LOTUS real-world evidence study and include patients who have been on treatment for over two years, contributing to a robust and growing portfolio of impactful data furthering our understanding of DAYBUE for the treatment of Rett syndrome,” said Ponni Subbiah, M.D., M.P.H., Acadia’s Senior Vice President, Global Head of Medical Affairs and Chief Medical Officer.

About Rett Syndrome
Rett syndrome is a rare, complex, neurodevelopmental disorder that may occur over four stages and affects approximately 6,000 to 9,000 patients in the U.S., with approximately 5,000 patients currently diagnosed according to an analysis of healthcare claims data.1-4 A child with Rett syndrome exhibits an early period of apparently normal development until six to 18 months, when their skills seem to slow down or stagnate. This is typically followed by a duration of regression when the child loses acquired communication skills and purposeful hand use. The child may then experience a plateau period in which they show mild recovery in cognitive interests, but body movements remain severely diminished. As they age, those living with Rett may continue to experience a stage of motor deterioration which can last the rest of the patient’s life.3 Rett syndrome is typically caused by a genetic mutation on the MECP2 gene.5 In preclinical studies, deficiency in MeCP2 function is thought to lead to impairment in synaptic communication, and the deficits in synaptic function may be associated with Rett manifestations.5-7
Symptoms of Rett syndrome may also include development of hand stereotypies, such as hand wringing and clapping, and gait abnormalities.8 Most Rett patients typically live into adulthood and require round-the-clock care.2,9
About DAYBUE™ (trofinetide)
Trofinetide is a synthetic analog of the N-terminal tripeptide of insulin-like growth factor 1. The mechanism by which trofinetide exerts therapeutic effects in patients with Rett syndrome is unknown. In animal studies, trofinetide has been shown to increase branching of dendrites and synaptic plasticity signals.10
Important Safety Information for DAYBUE™ (trofinetide)
DAYBUE is available as an oral solution (200 mg/mL).
