Abeona Therapeutics, Inc. is enrolling patients in a Phase I/II non-randomized, open-label clinical trial studying a one-time gene therapy for Sanfilippo syndrome type A (MPS IIIA). They have entitled this study ‘The Transpher A Study.’ Caregivers interested in enrolling their children can visit AbeonaTrials.com to take an eligibility survey and learn more about the study. Additional details can be found at ClinicalTrials.gov under study number NCT02716246 or by contacting email@example.com.
Study Locations: University of Minnesota in the Twin Cities; and New York University in New York City.
The search is on for Gaucher disease patients who fit the eligibility criteria for the Lysosomal Disease Network’s ongoing research study entitled “Role of Oxidative Stress and Inflammation in Type 1 Gaucher Disease (GD1): Potential Use of Antioxidant/Anti-inflammatory Medications.” (The Rare Diseases Clinical Research Network will make every effort to enroll all the patients it can, but it cannot make any guarantees that it will be able to enroll everyone in a particular study who wants to participate.) Many details about this study can be found at ClinicalTrials.gov under its study number NCT02583672.
Briefly, the purpose of this study is to measure blood and brain chemicals related to oxidative stress and inflammation in healthy volunteers and individuals with type 1 Gaucher disease (“GD1”). The investigators want to learn if these levels are abnormal in patients with GD1. They will also examine if there is a change in these blood and brain chemicals in GD1 patients after treatment with orally-administered N-acetylcysteine (“NAC”). NAC is available both as a prescription medication and as a “natural supplement” product in some retail markets. NAC has antioxidant and anti-inflammatory effects, and has been used for many years for the treatment of lung diseases, such as chronic obstructive pulmonary disease, and cystic fibrosis. The findings from this study may add to our understanding of how Gaucher disease causes tissue damage, and may lead to better treatment options for GD1.
The principal investigator of this study is Reena Kartha, PhD, located at the University of Minnesota in the Twin Cities. To see if you may be eligible to participate, first read the entry at ClinicalTrials.gov, and after that, you may e-mail your questions to Dr. Kartha at the University of Minnesota. Thank you for your time and consideration!

A research team led by Simon Körver of Amsterdam Academic Medical Center, University of Amsterdam’s Department of Endocrinology and Metabolism, has conducted and published in-depth analyses of forty-six published research studies that included the results of brain MRI investigations in 1,276 Fabry disease patients. These research studies were identified using Pubmed, EMBASE and CINAHL databases dated from inception to February 15, 2018. The researchers assessed the prevalence, severity, location and course of white matter lesions in these Fabry disease patients. Prevalence and severity were assessed for all patients combined, as well as divided by gender. They systematically reviewed the studies’ evidence on the relation between white matter lesions, disease characteristics, and clinical parameters.
One of their findings is that men and women showed comparable prevalence and severity of white matter lesions. Males, however, were significantly younger at time of white matter lesion assessment. Follow-up brain MRI in both men and women 38 months later revealed white matter lesion progression in 24.6% of patients, with and without enzyme replacement therapy, but at an earlier age in men.
Among their conclusions is that a significant group of Fabry disease patients has substantial white matter lesions, and male patients develop white matter lesions earlier compared to female patients. They suggested that future studies should focus on longitudinal brain MRI follow-up using state-of-the-art imaging techniques. They also suggested a clinical focus on the consequences of white matter lesions in Fabry disease patients. The article dives deeply into the details of their important findings.
National Institute of Neurological Disorders and Stroke (NINDS) at NIH has awarded $229,560 to Collaborations Pharmaceuticals Inc of Raleigh, NC to initiate a project at Washington University (St. Louis, MO) aimed at developing an enzyme replacement therapy to treat infantile Batten disease, also known as CLN1. The company will partner with Batten disease researcher Jonathan Cooper, PhD, Professor of Pediatrics at Washington University School of Medicine.
This treatment approach, originally funded by Taylor’s Tale (an LDN-affiliated patient advocacy group) and NINDS, began in the lab of Sandra Hofmann, MD, PhD, at the University of Texas Southwestern (Dallas, TX). Supported by these funds, Dr. Hofmann and her research team performed extensive development of the protein as well as pre-clinical assessment. Taylor’s Tale, a 501(c)3 public charity based in Charlotte, NC, funded Dr. Hofmann’s work beginning in 2007.
Moving forward, Collaborations Pharmaceuticals Inc will further develop the PPT1 enzyme, setting the stage for future clinical studies of this potential treatment for CLN1. In 2017 Collaborations Pharmaceuticals Inc received Orphan Drug Designation from the FDA for this PPT1 enzyme.
Collaborations Pharmaceuticals Inc is led by CEO Sean Ekins, PhD, who is also the President, CEO, and co-founder of Phoenix Nest, Inc.
The Legacy of Angels Foundation, which vigorously supports research into treatments and a cure for Krabbe disease and Cystic Fibrosis, and works to promote the expansion of newborn screening, announces the recipient of the 2019 Sue Rosenau Legacy Award. The award was created to honor the late Co-Founder and Chief Operating Officer of The Legacy of Angels Foundation, Sue Rosenau. This remarkable woman died on July 31st, 2018. To keep Sue’s legacy alive within the Foundation and community at large, The Legacy of Angels Foundation honors an individual for his\her achievements in Sue’s name each year. This legacy award recognizes an inspirational leader who has delivered extraordinary contributions, worked to propel progress towards a better treatment, and continuously gives altruistic support to the patient community; a replica of Sue Rosenau.
This year’s recipient is Dr. David A. Wenger, PhD, Director of the Lysosomal Disease Testing Laboratory at Sidney Kimmel Medical College (formerly Jefferson Medical College), part of Thomas Jefferson University in Philadelphia, Pennsylvania. This laboratory was established in 1973 by Dr. Wenger, and currently receives the largest number of samples for lysosomal diseases in the world. Testing has resulted in the diagnosis of over 4,600 individuals with a lysosomal disease.
Dr. Wenger is known for being the first to purify the missing enzyme in Krabbe disease, GALC, and the first to clone the GALC cDNA gene. He’s also identified over 100 mutations causing Krabbe disease in humans, successfully placed human and mouse GALC cDNA into several viral vectors including retroviral, adeno-associated viruses, lentiviruses and SV40. Dr. Wenger has transduced oligodendrocytes from the twitcher mouse with viral vectors containing human GALC cDNA, and corrected them to a normal phenotype. He has published many prominent peer-reviewed journal articles. Thanks to Dr. Wenger’s five decades of commitment and hard work, the Krabbe disease community remains hopeful that a clinical trial for Krabbe disease will be available by 2020.
