The ORCA (Observer-Reported Communication Ability) outcome measure

In 2018, FAST funded Dr. Bryce Reeve of Duke University to create a novel communication measurement tool as an outcome measure assessment of caregiver observations of a child’s ability for expressive communication in nonverbal patients with complex communication needs like Angelman syndrome (AS).  We are happy to announce that not only was Dr. Reeve successful in creating such a tool, but that it is being used by others in the Angelman space. This successful partnership and strong engagement with the Angelman community allowed the development of the Observer-Reported Communication Ability (ORCA) measure to be fast-tracked (<1.5 years from conception to having a measure). 

In a FAST survey among its Facebook members, 332 parents/caregivers indicated one of the most important improvements they wanted to see in their child with AS was changes in their communication. In response, FAST made improvements in communication ability one of the key markers for effectiveness of therapies to be tested in clinical trials. However, there lacked good quality parent/caregiver-reported measures of communication ability that would provide a reliable and valid assessment for individuals with AS. Recognizing this limitation, the FAST organization partnered with the Center for Health Measurement (CHM) at Duke University School of Medicine to design and evaluate a measure with the goal to use the measure in clinical trials to detect change in communication ability over time.

As a result, CHM, in collaboration with FAST, designed the Observer-Reported Communication Ability measure with direct feedback and involvement from the AS community. FAST funded the creation of the ORCA as part of our Angelman Biomarker and Outcome Measure Initiative (ABOM) efforts.  The purpose of the ABOM initiative is to create and/or identify biomarkers and outcome measures to be used in a pre-competitive spirit, non-proprietary manner across all parties’ interest in developing therapeutics for Angelman syndrome.  One of FAST’s goals in funding Dr. Reeve’s grant was to provide this valuable tool for researchers within the Angelman space, as well as for other disorders.

The ORCA measure includes 72 questions that capture various types of expressive, receptive, and pragmatic forms of communication and is able to place each individual with AS along a continuum of communication ability that allows for examination of their changes over time. The ORCA does not rely on speech, but allows gestures, vocalizations, and use of aids to capture communication ability. It takes about 15-20 minutes for a parent/caregiver to complete the measure independently without the help of a clinician or speech language pathologist.

The ORCA measure was designed following best practice recommendations by the U.S. Food and Drug Administration (FDA) and other organizations. First, the CHM team conducted in-depth interviews with both caregivers of individuals with AS and communication experts with experience working with individuals with AS to identify relevant types of communication behaviors. From these interviews, the CHM team learned of 22 communication concepts that were important to include on the ORCA measure such as seeking attention, requesting “more” of something (e.g., food), making choices, and greeting people. Second, the CHM team conducted additional interviews with caregivers of individuals with AS to make sure the questions included in ORCA were understandable and appropriate. Third, the CHM team collected responses to the ORCA questionnaire from 290 caregivers/parents of individuals with AS. With this data, the CHM was able to find strong evidence for both the reliability and validity of the ORCA measure to capture communication ability. All these steps are currently being written-up by the CHM team and FAST representatives and will be published in the scientific literature and shared with the FDA.

The ORCA measure is now being used in clinical trials and natural history studies for individuals with AS. Additionally, the CHM team is working to translate the English version of the ORCA into other languages so it may be used globally. Also, the ORCA measure may be used in other conditions/disorders that have significant communication deficits. 

Dr. Reeve is the Director for the Center for Health Measurement, as well as a Professor of Population Health Sciences and Pediatrics within the Duke University School of Medicine. Dr. Reeve is an internationally recognized psychometrician.  Dr. Reeve’s areas of expertise include developing patient-reported questionnaires using qualitative and quantitative methodologies and the integration of patient-reported data in research and healthcare delivery to inform decision-making. 

FAST Awards Drs. Silverman (UC-Davis) and Duis (Children’s Hospital Colorado) Grant to Study Gait as an Outcome Measure for Angelman Syndrome

Movement disorders affect nearly all individuals with Angelman syndrome (AS), with the most common concerns being spasticity, ataxia (as observed in the majority of ambulatory individuals), tremor, and muscle weakness. Clinically, over time, individuals may develop a crouched gait which can cause a progressive decline in mobility.  Similar motor disorders are observed in Angelman syndrome rodent models; dysfunction on the rotarod and reduced activity have been consistently reported in AS rodents. Under this grant, this translational research will explore various aspects of gait across different age groups and will be assessed and compared from both a non-clinical (rodent) and clinical (human) perspective.

Current patient mobility tests such as the 6-minute walking test or the 4-stair climbing test are inaccurate, lack rigor and reproducibility because they are highly dependent on patient motivation at the time of assessment and are not granular enough to discover quality changes in gait over time. They represent a single time point evaluation in a controlled environment, where the patients must travel to be assessed. Functional assessments are often not representative of a skill set when a patient is in their own environment. In addition, there is associated anxiety in unfamiliar environments for both the patient and the caregiver. Knowing that an individual will perform most accurately in a familiar environment, utilizing a measure that can be applied in that setting is ideal.   

Current mobility tests in humans and rodents can be inaccurate, or not translatable; therefore, improved motor-based outcomes that can be assessed across species for gross motor skills, fine motor skills, and gait quality, require further dedicated research and resources. Drs. Duis and Silverman have narrowed down and developed several outcome assessments that can be utilized in parallel across both rodents and humans.  This grant focuses on various spatial and temporal aspects of gait as an outcome measure in both preclinical (rodent) and clinical (human) research models, and will assess how that changes across developmental ages.  

This study will test the production and accuracy of sensor-based technology in individuals with AS across all genetic subtypes (deletion, UPD, ICD, UBE3A mutation), as well as AS rodents in relationship to gross and fine motor markers. Dr. Duis will recruit 40 individuals with AS for the clinical half of the study.  Drs. Duis and Silverman will utilize cutting edge sensor-based technology such as DigiGATE, ActiMyo® (using wearable brace-anklets to collect a wide variety of motor metrics), gait laboratory assessments via treadmills and 3D motion, and Zeno walkway.   Drs. Silverman and Duis will also identify spatial and temporal parameters in the Ube3a mouse and the FAST Ube3a rat model.  The information developed through this grant will provide truly translational outcome measures to test therapeutics across age groups in both rodent and human, with the goal of expediating its utility for human clinical trials.

By increasing the number of relevant, innovative, in vivo functional outcome measures in our wheelhouse, we will create more opportunities for identifying and moving forward successful medical interventions where we have accurate ways to assess motor improvements over time.

FAST update on the impact of Covid-19

While the world as we know it has changed, abruptly and dramatically, we at FAST want you to know that we are here and we continue to move forward in our mission to cure Angelman syndrome.

What COVID-19 precautions should parents of children with Angelman syndrome be taking?

Although individuals with Angelman syndrome are not known to be in the Center for Disease Control defined higher risk categories, the concerns about infection are always heightened in our community. In addition to the preventive measures we are all now very much aware of (washing hands, social distancing, disinfecting, etc.), here are a few resources you may find helpful:

How do school closures affect our children with Angelman syndrome?

We realize that as a community, our kids being home from school is more complicated than it is for their neurotypical peers. Most of our children with Angelman syndrome have IEPs (Individualized Educational Plans) which makes distance learning much more challenging. Without any formal training, we are now acting as educators, para-educators, therapists, social workers, and behaviorists. If you haven’t already done so, reach out to your child’s educational team to request a tele-consult for guidance on your child’s unique needs.

FAST advises all of us to take a deep breath, be kind to ourselves, be patient, and check out some of these helpful resources:

What local resources are available for support?

FAST has complied a list of potential resources for families within the United States that may be faced with hardship or are searching for local resources.

What is happening with FAST-funded research?

FAST has recently approved funding for three novel research projects and have several additional research contracts in process. We realize that the state mandated closures will most likely delay progress in the labs; however, as soon as restrictions are lifted, our researchers are ready, excited, and anxious to get back to the work of developing therapeutics to treat all individuals with Angelman syndrome. FAST will be sharing summaries of our exciting new research projects and our new caregiver support initiatives soon, so stay tuned!

What is happening with the GeneTx Biotherapeutics’ clinical trial?

Scott Stromatt, M.D., CMO of GeneTx Biotherapeutics provided the following update,

“The first group of patients in the clinical trial of GTX-102 have received their first dose. The clinical trial is proceeding as planned and we are closely monitoring the COVID-19 pandemic and how it might impact this clinical study. Patient safety is paramount and we are making adjustments as necessary to continue the required monitoring while reducing the burden to families where possible. The FDA has also recognized the need for flexibility for patients in clinical trials and issued a document to help companies implement changes to studies in-tended to help protect patients during this difficult time. One site is activated and treating patients, while the other six sites are in various stages of the activation process. The pandemic has slowed down the site activation process as each institution is addressing the COVID-19 pandemic in their region.”

What is happening with Ovid Therapeutic’s Angelman Trials?

Ovid clinical trials are continuing. We are closely monitoring COVID-19 and the evolving impact on families in our clinical trials. Every location where our clinical trials are being conducted faces different challenges and disruptions, so it is crucial that families and site study teams remain in close contact. Ovid is in regular contact with each site to provide guidance. In the event you lose contact with your study team, please contact Ovid and we will provide immediate support.

Currently, Ovid has two ongoing clinical trials in Angelman syndrome: The Phase 3 NEPTUNE study, and the Open-Label ELARA study. Both of these clinical trials are proceeding. The safety of every member of the Angelman community is the core focus for Ovid during this global crisis, and we plan to proceed with empathy, integrity and responsibility.

What is happening with the Angelman Natural History Trial?

As you are probably aware, all of the institutions that are involved in the ongoing Angelman Syndrome Natural History study have suspended non-urgent clinical operations, including all elective surgeries, clinic visits, and research visits, until the pandemic is under control and the physical distancing recommendations are lifted. While we hope that research visits can be conducted again from May-June 2020 onwards, no one knows when normal operations will resume at each institution.

We greatly appreciate your ongoing support of our study. The health and safety of our families is paramount, so we will not be having in-person visits until it is safe to do so again. We plan to continue with the Angelman Syndrome Natural History study by completing the questionnaires and standardized assessments that can be performed remotely via telephone calls, Skype, Zoom, or other means.

FAST funds pioneering infrastructure grant

FAST is thrilled to announce a grant to our continued partners and renowned scientists dedicated to advancing therapeutics for Angelman syndrome – David Segal, Ph.D., Jill Silverman, Ph.D., and the team at the University of California, Davis.  This grant provides the funding to build a lab devoted to Angelman syndrome (AS) research, establishing an infrastructure in which this team can evaluate multiple therapeutics simultaneously.

Dr. Jill Silverman is a behavioral neuroscientist with 18 years of training and experience focusing on preclinical rodent model systems with a strong emphasis in neurodevelopmental disorders and intellectual disability.

Dr. David Segal is a UC Davis professor of Biochemistry and Molecular Medicine with joint appointments in the Genome Center, the MIND Institute, and the Department of Pharmacology.  His area of expertise is in gene editing.

This funding will:

  • Create a stable infrastructure for rapid testing of potential therapeutics in AS rodent models through at least 2025
  • Train and retain staff dedicated to these studies, creating a new generation of scientists focused on AS research with combined expertise in molecular and behavioral components of AS
  • Provide lab equipment and supplies
  • Maintain AS cell lines and rodent model colonies at the University
  • Provide long term stability for this dedicated team to keep their focus on identifying and evaluating potential therapeutics for the treatment of Angelman syndrome

Drug evaluation is incredibly complex as various animal models and cell lines need to be carefully and thoroughly evaluated in order to gain accurate conclusions. This team has dedicated their careers to perfecting this task, and have become key opinion leaders in understanding Angelman syndrome specific models. Dr. Silverman has developed the experimental design, in collaboration with Dr. Segal, validated and standardized testing procedures, and will oversee all aspects of results interpretation.  Dr. Segal will direct the molecular analysis of the experiments.  They bring with them an impressive team of geneticists and researchers with vast experience in working with disease specific models. This program will allow external researchers and industry partners to have access to this wealth of expertise.

There are multiple pharmaceutical companies that have potentially promising therapeutics for the treatment of AS.  However, they do not have expertise in AS, or the specific tools necessary to properly evaluate these drugs for this population.  This infrastructure grant allows AS experts to provide those services and elucidate if a potential therapeutic warrants further development toward potential human clinical trials.

As examples, two new projects are currently being sent to this UC Davis team:

  • Evaluation of a small molecule in Angelman rodent models that was recently reported to rescue deficits in motor function and learning in an adult AS mouse model.  The lab will seek to independently validate these reports in mice and rats.
  • Screening of a new drug library in AS reporter neurons.  These compounds will be evaluated in primary neuronal cultures and carefully evaluate for paternal Ube3a gene activation.

FAST is incredibly hopeful about therapeutics already in and nearing human clinical trials.  But we are not finished until every person with Angelman syndrome sees a meaningful therapeutic benefit.  We keep pushing, and this lab with these amazing individuals will be part of what enables us to do this even more efficiently and effectively.

Angelman Syndrome Infrastructure Grant Update

From Dr. David Segal, Dr. Jill Silverman, and Dr. Kyle Fink at UC Davis

Having rebounded from the limiting conditions of COVID-19 restrictions, the Infrastructure Team is hard at work for the Angelman syndrome (AS) community. We have been busy building a lab that is devoted to Angelman syndrome research, establishing an infrastructure in which our group can evaluate multiple therapeutics simultaneously. The four key areas that we have been working on are:

Area 1) Antisense Oligonucleotides (ASO): Our top priority is testing rat specific ASOs in our AS rat model to understand the molecular biology that underlies effects observed in clinical trials. This information could help inform near term clinical trials as well as test our translation research endpoints.

Area 2) Known Compounds: A major area of focus is evaluating drugs that have shown some utility for Angelman syndrome in the scientific literature. We are currently performing behavioral pharmacology on three novel compounds in the AS mouse.  We know that these compounds are safe and effective in other conditions, and if they are validated and well characterized, showing robust behavioral changes in AS models, they could be prioritized for clinical trials.

Area 3) Unknown Compounds: We are working with various pharmaceutical companies to robustly screen and evaluate their proprietary compound libraries/therapeutic targets. Our aim is to de-risk new potential therapeutics for efficacy in Angelman syndrome. We are screening 2-3 libraries of compounds in fluorescent reporter neurons. In this way, we capture compounds previously identified for particular targets (Area 2) as well as completely new compounds that we don’t yet know to be useful.

 Area 4) Biomarkers: We are starting new experiments to look for biomarkers that might provide molecular clues to response to treatments. We have prioritized 24 candidate proteins to be assessed in multiple brain regions, cerebral spinal fluid (CSF), and plasma in multiple rodent models of AS that are currently being maintained at UC Davis through the infrastructure effort. These candidates will also be assessed in individuals with AS, in collaboration with Dr. Jessica Duis, using plasma and the existing biobank of samples in her lab. This effort leverages our unique tools and animal models with the knowledge and assistance of the broader scientific AS community.

We will continue to provide updates on a regular basis! 

“As you can see, we are hard at work trying to understand how these drugs can affect the course of Angelman syndrome. We are grateful to FAST for giving us the opportunity to bring the impressive capabilities at UC Davis to serve our Angelman community”

Dr. Segal.

About Angelman Syndrome

Angelman syndrome is a rare, neurogenetic disorder caused by loss-of-function of the maternally inherited allele of the UBE3A gene. It is estimated to affect 1 in 12,000 to 1 in 20,000 people globally. Individuals with Angelman syndrome have developmental delays, balance issues, motor impairment, and debilitating seizures. Some are unable to walk and most do not speak. While individuals with Angelman syndrome have a normal lifespan, they require continuous care and are unable to live independently. There are currently no approved therapies for Angelman syndrome; however, several symptoms of this disorder can be reversed in adult animal models of Angelman syndrome, suggesting that improvement of symptoms can potentially be achieved at any age.

Community statement from Ionis

 Dear Angelman Syndrome Community, 

We are writing this letter to share with you an update on our progress towards initiating our clinical trial in people living with Angelman syndrome. Last year was incredibly difficult on so many levels, and while 2021 will continue to have its challenges, we remain hopeful that our lives will begin to return to normal, and that there will be many great advancements towards a treatment for those living Angelman syndrome in the year ahead. 

As we announced in December 2020, we anticipate starting our clinical trial in the latter half of 2021, and we remain on track to meet that goal. We are completing the necessary preclinical studies with our lead compound and we are confident that we have selected best compound to take forward as a potential treatment for the broadest Angelman syndrome population. We have also begun preparing for the operational activities to launch our clinical trial. Some of those activities include discussions with local regulatory authorities in the US and other countries, site identification, as well as the development of Angelman syndrome specific tools, to create optimal opportunities to capture and measure potential participant changes that may be seen in the clinical trial. 

We are on track to initiate the global Phase 1-2a study later this year. The study will enroll up to 50 participants, and it will include a broad age range from young kids to adults. The primary goal of this first study is to determine the safety and tolerability of our drug. The study will include several clinical assessments completed at the clinic visits, as well as questionnaires that the parents or caregivers will complete at home. 

We understand that it’s vitally important to communicate often with the community and we are committed to providing regular updates on our progress. Our goal is to keep you informed on the clinical trial process, the activities related to the study start up, and the expected timelines. 

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 continuing our remarkable partnership with the community as we advance towards a treatment for Angelman syndrome.
