Clinical Research: A sampling of current studies
Boston Children’s is a focal point for neurology research. We are a member site in two NIH consortia for clinical trials, NeuroNEXT and NIH StrokeNet. Below is just a selection of some of our other ongoing clinical research studies.
Genetics of severe early onset epilepsies
This long-term study, led by Annapurna Poduri, MD, seeks to identify genetic alterations that cause severe early-onset epilepsies, focusing on epileptic encepha¬lopathies and Ohtahara syndrome in particular, with the goal of improving diagnosis and treatment.
The Rett Syndrome Research Program at Boston Children’s Hospital, led by David Lieberman, MD, PhD and Mustafa Sahin, MD, PhD, is committed to advancing our understanding of Rett syndrome and MECP2-related disorders by conducting research studies for patients with these rare neurodevelopmental disorders. In addition to offering multiple interventional clinical trials, we are also an active member of the NIH-sponsored Rett & Related Disorders Natural History Study and offering a new innovative biomarker study with two investigational devices that can track motion, breathing, and sleep of subjects through the collection of biometric, physiologic and electronic clinical outcome assessment data to be used for future clinical trials.
CDKL5 deficiency disorder
Boston Children’s Hospital’s CDKL5 Center of Excellence (COE), led by Heather Olson, MD, offers a comprehensive clinical care program dedicated to the care and evaluation of children and adults with CDKL5 deficiency disorder (CDD). The BCH COE enrolls patients in our clinic-based research program designed in collaboration with the other COEs and in the newly launched NIH UO1 funded International CDKL5 Clinical Research Network. We also have a strong collaborative network of researchers for translational and basic science CDKL5 research, which can be done in parallel with studies in our clinical center, including several interventional clinical trials.
PTEN Hamartoma Tumor Syndrome (PHTS)
The Multi-Disciplinary PTEN program, led by Siddharth Srivastava, MD in collaboration with the Developmental Synaptopathies Consortium, is conducting a Phase I/II clinical trial of the mTOR inhibitor, everolimus (Afinitor, Novartis Pharmaceuticals) in children and adolescents with PTEN mutations (U54NS092090). The primary aim of the study is to evaluate the safety of everolimus in this population of patients. Secondary outcomes include the short-term efficacy of everolimus on neurocognition and behavior, electrophysiological responses, dermatological features, and the microbiome of individuals with PTEN mutations.
Pediatric Status Epilepticus Research Group (pSERG)
pSERG is an international consortium coordinated out of Boston Children’s Hospital and lead by Dr. Tobias Loddenkemper. This consortium is developing a registry of refractory status epilepticus episodes with the goal of investigating outcomes of prolonged seizures that are resistant to at least two lines of antiepileptic rescue medications.
Tuberous sclerosis complex (TSC)
The Multi-Disciplinary Tuberous Sclerosis Program, led by Mustafa Sahin, MD, PhD, is currently conducting a clinical trial of the antiepileptic vigabatrin (Sabril, Lundbeck Pharmaceuticals). The primary objective of the study is to test whether early treatment versus delayed treatment with vigabatrin in infants with TSC will have a positive impact of developmental outcomes at 24 months of age. A second objective is to determine if early intervention will prevent or lower the risk of the child developing infantile spasms and refractory seizures
Duchenne Muscular Dystrophy
The Neuromuscular Program at Boston Children’s, led by Basil Darras, MD, is conducting a Phase III study of Golodirsen and Casimersen (Sarepta 4045-301 and 4045-302) of these two exon skipping drugs with the aim to ncrease production of dystrophin protein in boys with DMD. Another phase II study is investigating the drug Pamrevlumab by Fibrogen Inc. in the hopes that it will slow muscle degeneration in boys with DMD. Lastly, another phase III study by Catabasis Pharmaceuticals is investigating the use of Edasalonexent in boys with DMD, to see if it could be a viable replacement for steroid therapy, with reduced negative side effects.
Spinal Muscular Atrophy
The Spinal Muscular Atrophy Program at Boston Children's Hospital is led by Basil Darras, MD. His program was part of Phase I , II, III trials testing the safety and efficacy of Nusinersen or Spinraza which was the first FDA approved treatment for SMA for all types of SMA. Spinraza works by altering the splicing of the SMN2 gene, leading to the increased production of fully functional SMN protein. We continue to follow our original trial patients, through an extension protocol. Biogen, maker of Spinraza is starting a new study, to test higher doses of Spinraza. Our program is also participating in the phase II & III trials of an oral small molecule, Risdiplam by Roche that is also designed to alter the splicing of the SMN2 gene. These studies; Firefish and Jewelfish studies led to Risdiplam being approved by the FDA in August 2020. Additionally, we have participated in AveXis Inc.’s, gene therapy for SMA type I patients(STR1VE), and SMA Type II patients (STRONG) using an AAV9 virus vector to deliver the SMN1 gene. STR1VE delivers the medication intravenously, and STRONG delivers the medication intrathecally. This gene therapy was FDA approved as Zolgensma, via IV administration for patients under 2 years of age. Lastly, we have started the TOPAZ trial, sponsored by Scholar Rock Inc., which is investigating a myostatin inhibitor, a muscle growth inhibitor to be used in combination therapy with other SMA therapies to improve muscle strength. The SMA Program also has an ongoing natural history study and is collecting specimens for a biorepository, which are sponsored by the charitable foundation, Cure SMA.
Janet Soul, MD, of Boston Children’s Fetal-Neonatal Neurology Program, is conducting a clinical trial directed at controlling neonatal seizures with bumetanide. Bumetanide is a diuretic that investigators at Boston Children’s and Massachusetts General Hospital have shown to lower chloride levels in the newborn brain, making neurons more responsive to GABA activation.
Neurofibromatosis and pediatric brain tumors
Nicole Ullrich, MD, PhD, Director of Neuro-Oncology, is a founding member of a national collaborative group currently conducting a series of clinical trials in patients with neurofibromatosis. Recent trials have included testing the MEK inhibitor binimetinib and Cabozantinib in neurofibromatosis type 1 (NF-1) and bevacizumab and crizotinib for vestibular schwannomas in NF-2. Ullrich was national study chair for a randomized, placebo-controlled trial of modafinil to reverse cognitive deficits in survivors of pediatric brain tumors through the Children's Oncology Group. She is opening a new study using memantine to prevent cognitive decline related to radiation for primary brain tumors in children.
Advanced seizure tracking and warning systems
Seizures frequently are not identified by patients and families. This trial, led by Tobias Loddenkemper, MD, tests novel, portable epilepsy monitoring sensors and tools that can detect seizures by means of autonomic nervous system features, patient movement and other vital signs and parameters. The devices allow for rescue measures and tracking of less severe seizures and treatment responses and may help patients gain better control over seizures.
The purpose of this study conducted by Alexander Rotenberg, MD, PhD (PI: Neurology) and Wen-Hann Tan, MD (co-I: Genetics & Genomics) is to evaluate the reliability and validity of select neurobehavioral assessments and EEG biomarkers as endpoints for future clinical trials in children and adults with Angelman Syndrome (AS). This multisite study is sponsored by Roche Pharmaceuticals.
Alexander Rotenberg, MD, PhD is conducting this study to validate a software solution for detecting absence seizures with wearable and clinical EEG systems. This project is both retrospective and prospective in nature and it is sponsored by Epihunter NV in collaboration with the Epilepsy Foundation.
