1. Momentum 1: A Multicenter, Double-blinded, Randomized, Placebo-Controlled, Parallel Group Study with Open-Label Extension Phase of Lorcaserin as Adjunctive Treatment In Subjects with Dravet Syndrome. (Olivia Kim-McManus, M.D.Mark Nespeca, M.D.)
The primary purpose of the study is to demonstrate that lorcaserin has superior efficacy compared to placebo on the percent change in frequency of convulsive seizures per 28 days in participants with Dravet syndrome. Participants will be randomized to receive lorcaserin administered as an oral suspension, twice daily for 14 weeks during the core treatment period. Dose will be based on body weight as follows: target dose for participants weighing 10 to less than (<) 20, 20 to <40, and greater than or equal to (>=) 40 kilogram (kg) will be 5, 10, and 20 milligram per day (mg/day) respectively. Based on clinical response and tolerability and within 2 weeks of treatment, dose can be increased up to 10, 20 mg/day for participants weighing 10 to <20, 20 to <40 kg respectively. Participants completing the core treatment period will enter a 12-week extension phase and will receive lorcaserin.

Richard Haas, M.D. | Natalie Guido-Estrada, M.D.

A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study of Trofinetide for the Treatment of Girls and Women with Rett Syndrome (phase 3)

This multi-site study will investigate the efficacy of treatment with oral Trofinetide versus placebo in girls and women with Rett syndrome. There are 184 subjects who are expected to be randomized (with a minimum of 12 subjects randomized for each age stratum [5-10 years old, 11-15 years old, and 16-20 years old]) with a total of 92 subjects per treatment. Subjects will receive an oral dose of Trofinetide or placebo, for up to 12 weeks. Dose will be based on weight. There is also an open-label extension of this study available.

1. Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Evaluate the Efficacy and Safety of Givinostat in Ambulant Patients with Duchenne Muscular Dystrophy

A total of 213 male ambulant subjects will be randomised 2:1 (givinostat:placebo). Subjects will be stratified for their concomitant use of steroids in four strata: 1) Deflazacort daily regimen; 2) Deflazacort intermittent regimen; 3) Other steroids daily regimen; 4) Other steroids intermittent regimen. The study duration is planned for 19 months.

2. Open-Label Extension for the Above Project

3. AVXS-101-RG-001 A Prospective Long-Term Registry of Patients with a Diagnosis of Spinal Muscular Atrophy (SMA)

Spinal muscular atrophy (SMA) is a neurogenetic disorder caused by a loss or mutation in the survival motor neuron 1 gene (SMN1) on chromosome 5q13, which leads to reduced SMN protein levels and a selective dysfunction of motor neurons. SMA is an autosomal recessive, early childhood disease with an incidence of 1:10,000 live births. SMA is the leading cause of infant mortality due to genetic diseases.Until recently, the mainstay of treatment for these patients was supportive medical care. However, advances in medical treatment focusing on gene replacement, gene enhancement, motor neuron protection and muscle enhancement is likely to change the management and prognosis of these patients in the future. The purpose of this registry is to assess the long term outcomes of patients with SMA in the context of advances in treatment options.

Multiple Sclerosis and Neuroinflammatory Disorders

Jennifer Graves, M.D., Ph.D., M.A.S. | Jennifer Yang, M.D.

1. NEOS:
A two-year randomized, three-arm, double-blind, non-inferiority study comparing the efficacy and safety of ofatumumab and siponimod versus fingolimod in pediatric patients with multiple sclerosis followed by an open-label extension: The main purpose of the study is to find out if ofatumumab and siponimod versus fingolimod are safe and beneficial to use in children/adolescents with MS aged 10 to 17 at the start of the study. This placebo controlled study is 2 years during the double blinded part of the study (core part) and up to 5 years in the open-label-extension part of the study. It involves MRIs, blood draws, functional testing and additional visits to monitor patients.

2.  Eyetracker Study
The visual system provides an opportune and elegant window into the inflammatory and degenerative aspects of MS. We can identify precise relationships between structural damage and functional outcomes that are difficult to achieve in other aspects of nervous system injury. In this study use technologically advanced eye tracking technology to analyze eye movement in MS patients and healthy controls, to learn more about the aspects of eye movement that cannot be seen with the naked eye, and how they are related to diseases of the central nervous system.

3. BioAging Study
Our BioAging study investigates the association of biological aging of senescent cells and aging in multiple sclerosis patients ages 14 and up. This study aims to identify potential pathways through which relapsing forms of MS advance into progressive forms of MS. This study consists of a single blood draw, and is now actively recruiting both MS and healthy control participants.

Observational Studies

4. PAW
The PAW study aims to investigate physical activity and wellness in pediatric neuroimmunological diseases through the use of physical activity questionnaires. This study will continue over the coming few years and consists of a few questionnaires completed at the time of a regularly scheduled neurology visit. PAW is currently actively recruiting pediatric subjects.

5. Diet and Relapses
The Diet and Relapses study explores the connection between rate of relapse and diet through the gut microbiome and amino acids found in the digestive tract. We hope to uncover the role that 25 (OH) vitamin D levels, fat and vegetable intake, and other nutrients take in the pediatric disease course, and to investigate the biological pathways relevant to this association.

Optional: By filling out a set of questionnaires, and a small blood draw, patients can help us to further understand pediatric MS.

6. PeMSDD Database Study
PeMSDD is a database registry study linked to the Diet and Relapses study. This registry strives to describe the number and characteristics of patients with suspected early onset demyelinating disases. This database will help investigators allied with the National Pediatric MS Center to support hypothesis generation, and study design development.

7. The CONNECT Registry (CONquering Neuroimmunology and Epilepsies ConsorTium)
A multicenter prospective cohort study of the clinical features and biomarker identification for autoimmune encephalitis, Landau-Kleffner Syndrome and Rasmussen encephalitis.

Doris Trauner, M.D.

1. Perinatal Arterial Stroke: A Multisite RCT of Intensive Infant Rehabilitation (I-ACQUIRE) 

This is an NIH StrokeNet-funded study to test the effectiveness of constraint-induced movement therapy on improving hand us in toddlers with hemiplegia caused by perinatal stroke. Children between the ages of 8-24 months are randomized to one of 3 groups, with either 3 hours/day or 6 hours/day of intensive occupational therapy for 4 weeks or “usual and customary” treatment.
