1. Evaluation of the Efficacy, Safety, and Tolerability of Sarizotan in Rett Syndrome With Respiratory Symptoms
This is a randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability and efficacy of multiple doses of sarizotan in patients with Rett syndrome with respiratory abnormalities. The study participants will be randomized to either sarizotan between 2 and 10 mg bid or placebo bid, based on age and weight criteria.
2. Natural History of Rett Syndrome & Related Disorders
The purpose of this study is to advance understanding of the natural history of Rett syndrome (RTT), MECP2-duplication disorder (MECP2 Dup), RTT-related disorders including CDKL5, FOXG1, and individuals with MECP2 mutations who do not have RTT including the range of clinical involvement and to correlate genotype-phenotype over a broad spectrum of phenotypes. While much has been learned about RTT, improvements are required in understanding the role of factors such as X chromosome inactivation, genetic background, and others including the environment, on the great variability observed even between individuals with the same MECP2 mutation. These data will be essential to the development and conduct of clinical trials that are anticipated from ongoing studies in animal models for RTT. This study will not include clinical trials, but should set the stage for such trials and other translational research projects (e.g., development of biomarkers).
3. A Randomized, double-blind, placebo-controlled, trial to investigate the efficacy and safety of cannabidiol oral solution (GWP42003-P, CBD-OS) in patients with Rett syndrome
This study will evaluate the efficacy of cannabidiol oral solution (GWP42003-P, CBD-OS) in reducing symptom severity when compared with placebo, in patients with Rett syndrome. The trial is recruiting a total of 252 females with Rett syndrome aged 2 to 18 years. The trial procedures include physical exams, blood and urine sampling, PK blood sampling, ECG, caregiver questionnaires, and a weekly symptom diary completed by the caregiver. Trial subjects will have the option to continue on to an ‘open-label’ period at the end of trial. The trial will last approximately 8 months, with 3 telephone consultations and 8 in-clinic visits.
4. A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study of Trofinetide for the Treatment of Girls and Women with Rett Syndrome (phase 3)
This study will investigate the efficacy of treatment with oral Trofinetide versus placebo in girls and women with Rett syndrome.184 subjects 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.
5. A 40-Week, Open-label Extension Study of Trofinetide for the Treatment of Girls and Women with Rett Syndrome
This is a 40-week, multicenter, open-label extension (OLE) study. Subjects who complete the preceding double-blind study will be eligible to enroll in the OLE. Study participants must be consented prior to the procedures being performed at the Week 12/end of treatment (EOT) visit of the preceding study. Procedures performed at the Week 12/EOT visit of the antecedent study will serve as the Baseline visit of this study. The study will have 2 periods: Treatment period of 40 weeks and Safety follow-up period.

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.
Dr. Jennifer Graves is involved in the following studies:
1. An Open-Label, Randomized,Multicenter, Active-Controlled, Parallel-Group Study to Evaluate the Safety, Tolerability, and Efficacy of BIIB017 in Pediatric Subjects Aged 10 to Less Than 18 Years for the Treatment of Relapsing-Remitting Multiple Sclerosis, With Optional Open-Label Extension
This study will evaluate the safety, tolerability, and descriptive efficacy of BIIB017 in pediatric participants with relapsing-remitting multiple sclerosis (RRMS) and to assess the pharmacokinetics (PK) of BIIB017 in pediatric participants with RRMS in Part 1. In Part 2, the study will evaluate the long-term safety of BIIB017 and further describe safety and the long-term multiple sclerosis (MS) outcomes after BIIB017 treatment in participants who completed the study treatment at Week 96 in Part 1 of the study.
2. CHARGE (Biogen 105MS306)
CHARGE is a Biogen-sponsored clinical trial investigating the safety, tolerability and efficacy of Plegridy (BIIB017, or peginterferon beta-1a) in comparison to Avonex (interferon beta-1a) in pediatric relapsing-remitting Multiple Sclerosis for volunteers 10-17 years old. While Plegridy reduces inflammation associated with MS relapse, Avonex reduces inflammation and suppresses the immune responses which attack the central nervous system in rMS. We will follow participants for up to 45 weeks collecting data from electrocardiograms (ECG), blood tests, MRI scans and questionnaires.

3. 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.

5. Outcomes of perinatal stroke
Unfunded, student research project (Bridget MacDonald, UC San Diego MS2)
This study explores the role of neonatal EEG in predicting developmental outcome in infants with perinatal stroke.
Dr. Dillon Chen is leading in the following research initiatives:
1. Understanding the roles of polysialic acid and Sialic acid-binding immunoglobulin-type lectins (Siglecs) in the developing brain and how they affect neuro-injury and neuro-inflammation
Perinatal and neonatal brain injury often leads to long-term morbidity including neurodevelopmental impairment. Understanding the effects of injury during these critical periods of brain development may result in improved morbidity and mortality for infants with brain injury. One of the most fundamental building blocks of the brain is the sialic acid and a major protein-bound sialic acid in the brain is polysialic acid (polySia). The goals of the project are to characterize and explore the functions and expression levels of polySia, Siglec-11 and Siglec-16 in the developing brain, especially in the setting of neural injury.
2. A simple method to detect neurologic disease in neonates
