PRAGUE, October 10, 2017 /PRNewswire/ --

  • Treatment with Ped-PRM significantly improved total sleep time (TST), sleep
    initiation and maintenance 
  • Parents' quality of life and satisfaction from children's sleep increased significantly
     
  • Ped-PRM is under review of the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP)  
  • First study manuscript to be published in the Journal of American Academy of Child & Adolescent Psychiatry 

Neurim Pharmaceuticals ("Neurim") presented top line results of the pivotal placebo-controlled phase III study of pediatric prolonged-release melatonin formulation ("PedPRM") in ASD children (age 2-18 years) who suffer from insomnia. The study's primary endpoint showed a clinically meaningful and statistically significant increase in total sleep time (p=0.034).  Participants slept on average 57.5 minutes longer at night with PedPRM compared to 9.14 with placebo. Sleep latency (SL) decreased by 39.6 minutes on average with PedPRM compared to 12.5 with placebo (p=0.011) without causing earlier wakeup time. Sleep maintenance, parents' quality of life and satisfaction of child's sleep also improved significantly. The beneficial effects of PedPRM were maintained over the long term. Furthermore, compliance with the age-appropriate PedPRM formulation was good and it had a favorable safety profile over the short and long term period. Main study results were presented during the World Sleep Congress (Prague, October 9-12), and later will be presented at the American Academy of Child & Adolescent Psychiatry (AACAP) 64th Annual Meeting, (Washington DC, from October 23-28, 2017), and are in press in the Journal of American Academy of Child & Adolescent Psychiatry.

"Children with Autism Spectrum Disorder suffer from significant sleep problems which exacerbate their behavioral and functional deficits, and are particularly challenging to their families. Currently, there are no approved therapeutic options for pediatric insomnia, and that is particularly problematic for children with ASD" said Professor Gringras, lead for the Children's Sleep Medicine Dept, Evelina London Children Hospital and Principal Investigator of the study. "The results of the study indicate that PedPRM is an effective and safe treatment which is well tolerated even in this challenging population. It is effective in improving sleep problems that have been refractory to the usual behavioural interventions in this population, and furthermore improves parental quality of life and satisfaction from their child's sleep," he added.

ABOUT PEDPRM AND NEU_CH_7911 PHASE III STUDY 

PedPRM is an age-appropriate formulation of prolonged-release melatonin, a hormone involved in regulation of the circadian clock and sleep. The innovative formulation was designed for populations with swallowing difficulties, such as children with ASD, in response to the unmet medical need in the field of pediatric insomnia under EU-PIP and US-FDA IND.

The pivotal phase III study was a randomized, double-blind, placebo-controlled, parallel group, multi-center (EU and USA) study in children with ASD or neurogenetic diseases and sleep disorders. 125 patients, who had not shown improvement after standard sleep behavioural intervention, received 2 weeks placebo run-in, and were then randomized to PedPRM (2mg with optional increase to 5mg) or placebo in the evening, for 13 weeks. Completers received PedPRM open-label for additional 13 weeks. Primary efficacy endpoint was defined as the difference between PedPRM and placebo in mean change from run-in baseline to the end of double-blind treatment period, in parent-reported TST (Daily Sleep and Nap Diary). Additional endpoints assessed children's sleep initiation and maintenance, behavioral and social functioning, as well as, parent's quality of life. Patients are now being followed up to 78 weeks to assess the long-term efficacy and safety of PedPRM and results will be presented during 2018.
