CHAPEL HILL, NC – September 16, 2019 – A marijuana plant extract, also known as cannabidiol (CBD), is being commonly used to improve anxiety, sleep problems, pain, and many other neurological conditions. Now UNC School of Medicine researchers show it may alleviate seizures and normalize brain rhythms in Angelman syndrome, a rare neurodevelopmental condition.

Published in the Journal of Clinical Investigation, the research conducted using Angelman syndrome animal models shows that CBD could benefit kids and adults with this serious condition, which is characterized by intellectual disability, lack of speech, brain rhythm dysfunction, and deleterious and often drug-resistant epilepsy.

“There is an unmet need for better treatments for kids with Angelman syndrome to help them live fuller lives and to aid their families and caregivers,” said Ben Philpot, PhD, Kenan Distinguished Professor of Cell Biology and Physiology and associate director of the UNC Neuroscience Center. “Our results show CBD could help the medical community safely meet this need.”

CBD, which is a major phytocannabinoid constituent of cannabis, has already shown to have anti-epileptic, anti-anxiety, and anti-psychotic effects. And in 2018, the FDA approved CBD for the treatment of seizures associated with two rare forms of epilepsy, but little is known about the potential anti-seizure and behavioral effects of CBD on Angelman symptom.

The Philpot lab is a leader in the creation of genetically modified mouse models of neurodevelopmental disorders, and they use these models to identify new treatments for various diseases, such as Rett, Pitt-Hopkins, and Angelman syndromes.

In experiments led by first author Bin Gu, PhD, a postdoctoral fellow in the Philpot lab, the UNC-Chapel Hill researchers systematically tested the beneficial effects of CBD on seizures, motor deficits, and brain activity abnormalities – as measured by EEG – in mice that genetically model Angelman syndrome, with the expectation that this information could guide eventual clinical use.

The researchers found that a single injection of CBD substantially lessened seizure severity in mice when the seizures were experimentally triggered by elevated body temperature or loud sounds. A typical anti-convulsant dose of CBD (100 mg/kg) caused mild sedation in mice but had little effect on motor coordination or balance. CBD also restored the normal brain rhythms which are commonly impaired in Angelman syndrome.

“We’re confident our study provides the preclinical framework necessary to better guide the rational development of CBD as a therapy to help lessen seizures associated with Angelman syndrome and other neurodevelopmental disorders,” Gu said.

Philpot and Gu added that patients and families should always seek advice from their physician before taking any CBD products, and that a human clinical trial is needed to fully understand its efficacy and safety.

Other authors were Madison Glass, Marie Rougié, Viktoriya Nikolova, Sheryl Moy, PhD, and Paul Carney, MD, all of UNC-Chapel Hill.

ASF Funded Research finds Critical Role of UBE3A
30 May

Role of UBE3A in the Developing Brain

Your ASF donations hard at work at UNC and Erasmus Medical Center in the Netherlands. This pivotal study demonstrated that UBE3A is most critical in the developing brain and plays a less vital role later on in life.

This is important in designing clinical trials and knowing when is the best time to treat. But what does this mean for our loved ones? “This means that while developing a therapy that permanently reinstates UBE3A might be optimal, even a treatment that gives back UBE3A during critical periods of brain development could be truly transformative!” – Ben Philpot, PhD University of North Carolina at Chapel Hill

See the article in Molecular Autism.

ASF AS Clinic at UNC Chapel Hill Studies Anxiety
30 May

Anxiety in Angelman Syndrome

Important work coming out of the ASF Clinic Network at the University of North Carolina at Chapel Hill. Did you know that anxiety concerns are reported in 40% of people with AS? Characterizing that anxiety is critically important to design tools that can tell us if therapeutics are working!

Read the published paper. 

Thank you to all of our families who visit the clinics and make this research possible! And thank you to all of those generous donations that make our clinics possible. 

Roche, Biogen and Ionis Announce Collaborative Research Partnership
20 May

Roche, Biogen and Ionis logos

See the following announcement from May 16, 2019.

Also, see a Q&A on this collaboration for more details.  

 

Dear Angelman Syndrome Community,

We, Roche, Biogen and Ionis, are amongst several companies working towards finding potential treatments for Angelman Syndrome (AS). While Roche and the Biogen/Ionis team have two independent research programs, we all share the common goal of bringing potential new therapies for AS into clinical trials in the future. Improving the understanding of AS is a very important step in the drug development process, and AS families are at the center of our efforts. We are writing this letter to share with you an update on some of our current work in AS.

Today, we announce our collaborative research partnership on two new studies that will improve the understanding of AS and guide the design of future drug studies:

One study is called the AS CSF and Biomarker Study and is led by Biogen. The aim is to find potential biomarkers, biological signs of disease, that can be measured in CSF (cerebrospinal fluid, which is the fluid around the brain and spinal cord). These biomarkers could then be used to check if a drug has an effect on AS.

The other study is called the AS Endpoint Study, and is led by Roche. The aim is to find ways to measure disease impact in the home and clinic, and use new technologies to learn about AS. These measurements (endpoints) and technologies focus on areas such as sleep, communication and brain activity.

These two studies do not involve any drug. Their purpose is to help design possible drug trials for AS in the future. The specific goals of these studies have not been covered before by other observational studies in AS. These studies are expected to start in the second half of 2019. More information will be available on ClinicalTrials.gov when the first sites are opened. We will let you know as soon as this information is available. 

Families will be able to join one or both of these studies, and they can also be part of other non-drug studies such as the FDA funded Natural History Study at the same time. As you may already know, gathering natural history data in Angelman Syndrome patients is a critical component to understanding the disease. To design the best clinical study for a treatment, we need to better understand the disease progression in the absence of a treatment. Taking part in non-drug studies typically does not prevent someone from taking part in any studies involving an investigational drug in the future, as long as the individual matches the inclusion criteria for a future drug study.

Our companies are working together on these two new studies, in collaboration with researchers and families in the Angelman community, so that important scientific information on AS is collected and shared. In parallel to these non-drug studies, our companies continue to independently research potential drug candidates for future clinical studies.

We are very grateful to all families who volunteer to take part in research and drug development efforts. Only with your support can we advance potential therapies towards clinical trials. We look forward to enhancing our partnership with the community by providing regular updates on the status of these studies and our independent programs.

Sincerely,
The Roche, Biogen and Ionis Teams

Dr. Harry Angelman Honored on International Angelman Day

Angelman Syndrome Foundation Honors Dr. Harry Angelman With International Angelman Day Celebration

 

ASF partners with AS father and advocate to celebrate global strides in Angelman syndrome research, patient care

AURORA, Ill. (Feb. 15, 2019) – Today, in celebration of International Angelman Day on Feb. 15, the Angelman Syndrome Foundation (ASF) partnered with Angelman syndrome (AS) advocate and father Peter Patterson to honor Dr. Harry Angelman, the British pediatrician who first identified Angelman syndrome. More than 50 years after Dr. Angelman’s discovery of this rare neurogenetic disorder, a plaque commemorating the global impact of his accomplishments was unveiled at Gosport Memorial Hospital in the United Kingdom today.

Plaque honoring Dr. Harry Angelman

The plaque installed at The War Memorial Hospital in Gosport (UK) when Harry Angleman retired too and passed away in 1996.

Patterson, who lost his son to Angelman syndrome in 2003, campaigned for years to have Dr. Angelman’s achievements recognized in the U.K. Thanks to his dedication, the plaque now rests where Dr. Angelman passed, minutes from where he retired in Lee-on-the-Solent.

In recognizing Dr. Angelman’s work, ceremony attendees also reflected on how far the global research community has come since his discovery, as well as the now global accessibility of ASF Angelman Syndrome Clinics (AS Clinics), founded by the ASF to provide the specific treatments that are desperately needed by people with AS of all ages.

“Dr. Angelman spent his life committed to helping those with Angelman syndrome, and we continue to honor his legacy by advancing patient care through the ASF AS Clinics,” says Eileen Braun, executive director of the Angelman Syndrome Foundation and mother to a young woman with AS. “After decades of ASF-funded research spanning the globe, we are so much closer to a cure. We are proud to continue his legacy by working hard every day to support families and fund important research aimed at finding treatments and ultimately a cure for AS.” 

Since 1996, the ASF has funded more than $10 million in research studying AS, the root cause of the disorder, potential therapeutics, and ultimately a cure. Of that, more than $2 million has funded researchers outside the U.S., including those in Australia, Canada, Israel, Japan, The Netherlands, and the U.K.

Most recently, the ASF, along with global partners, funded groundbreaking research to support the world’s largest newborn screening study for four rare genetic disorders, including AS. This pilot study, currently underway by Associate Professor David Godler from the Murdoch Children’s Research Institute in Melbourne, Australia, will validate the screening tool on a large-scale—ultimately leading to earlier and more accurate diagnosis, allowing therapies to be implemented at a much younger age. 

“If we could have newborn screening for Angelman syndrome, it would help families by eliminating the diagnostic odyssey and having therapies available right from the beginning,” says Dr. Jessica Duis, MD, MS, Director of the Comprehensive Angelman Syndrome and Prader-Willi Clinics at Vanderbilt University Medical Center. “We know that if we implement these therapies early, that we will change the course of these disorders as we know them today.”

For Patterson, having an early diagnosis of AS for his son, Anthony, would have been life-changing. His family struggled for years without knowing what was wrong with their son, dealing with confusion and stress while battling the host of health challenges that come with AS.

“Dr. Angelman identified my son’s health issues,” said Patterson. “With his diagnosis, it was comforting to know what was wrong. I want his work to be recognized in hopes of supporting more families who are struggling with Angelman syndrome around the world.”

Clinical Trial of OV101 in Pediatric Patients
06 Dec

On December 6, 2018, Ovid Therapeutics announced plans to move ahead with a single, pivotal Phase 3 trial of once-daily dosing of OV101 in pediatric patients with Angelman syndrome. This is based on its End-of-Phase 2 Meeting with the U.S. Food and Drug Administration (FDA). If successful, the Phase 3 efficacy and safety trial is intended to support a New Drug Application (NDA) for OV101 in AS.
