ASF Funded Research finds Critical Role of UBE3A

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 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

Newborn Screening Study for Rare Disorders

World’s Largest Newborn Screening Study for Angelman, Prader-Willi, Fragile X and Dup15q Syndromes Launches

Nonprofits co-fund feasibility study to test screening tool for 75,000 newborns for Angelman, Prader-Willi, Fragile X and Dup15q Syndromes

AURORA, Ill., and WALNUT, Calif. (November 8, 2018) – The Angelman Syndrome Foundation and the Foundation for Prader-Willi Research announce funding to support the world’s largest newborn screening study for four rare genetic disorders: Angelman, Prader-Willi, Fragile X and Dup15q syndromes. The Victorian Medical Research Acceleration Fund this year also contributed $100,000 toward the project.

In a pilot study, Associate Professor David Godler from the Murdoch Children’s Research Institute in Melbourne, Australia, will screen 75,000 newborns, establishing the feasibility of the test for large-scale screening.

“Newborn screening means families with loved ones with Angelman, Prader-Willi, Fragile X and Dup15q syndromes find a diagnosis in weeks instead of years, avoiding a painful diagnostic journey. And, if we can diagnose individuals earlier, we have the best chance of reversing the effects and improving their quality of life much sooner,” says Eileen Braun, Executive Director of the Angelman Syndrome Foundation and mother to a young woman with Angelman syndrome (AS). “Research, including studies funded by the ASF, is moving quickly toward therapeutics and a cure for AS, and experts are now pinpointing the optimal window for applying a cure. The sooner we can diagnose, the sooner we can apply life-changing treatments.”

“Having a cost-effective test to accurately diagnose these syndromes in the newborn period is key to ensuring that families receive optimal medical care and support,” adds Theresa Strong, Director of Research Programs for FPWR. “The study will validate the newborn screening tool so that, once approved for use, it can be used to screen all babies in the newborn period.”

“This would allow individuals to have standard-of-care therapies 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. “For example, for Prader-Willi Syndrome (PWS), this means growth hormones and early intervention therapies that we know from experience have huge benefits.”

When available, life-changing therapeutics and a cure for AS could be implemented within the first weeks of life.

Current rates of incidence of PWS and AS vary widely from 1:12,000 and 1:30,000 live births. The study will also help understand the true incidence and full spectrum of these disorders in the population. 

“I believe the prevalence of these disorders is underestimated, because all tests used to diagnose these conditions were developed more than 10 years ago and are not as sensitive,” says A/Prof. Godler.

AS in particular is often not diagnosed until individuals are between one to three years of age and delays are noted, significantly delaying therapies and creating stress and hardship for families.

The study was inspired by A/Prof. Godler’s previous work to develop a test called MS-QMA, which can accurately diagnose Fragile X syndrome, a common genetic disorder linked to autism spectrum disorder. With additional funding, he found the test could also be used to screen for PWS, AS and Dup15q.

“My dream is to one day have our tests included in newborn screenings around the world,” says A/Prof Godler. “That means the families with babies with these conditions get the support and care they need from day one.”

A/Prof Godler is also a member of the Paediatrics Department of the University of Melbourne.

A/Prof Godler’s Fragile X test is being trialed on samples of 100,000 babies, thanks to an earlier $800,000 Australian National Medical Research Council grant and a $500,000 Australian Federal Government’s Medical Research Future Fund fellowship awarded in 2015 and 2018, respectively.

About the Angelman Syndrome Foundation (ASF)

The Angelman Syndrome Foundation’s mission is to advance the awareness and treatment of Angelman syndrome through education and information, research, and support for individuals with Angelman syndrome, their families and other concerned parties. The ASF sponsors Angelman syndrome research through grants to researchers pursuing treatments and a cure for Angelman syndrome. Since 1996, the ASF has funded 101 research grants totaling more than $9.5 million. The ASF has awarded a majority of these funds ($9.2 million) beginning in 2005. 

About Prader-Willi syndrome (PWS)
Prader-Willi syndrome
is a rare, genetic disorder affecting approximately 1 in 15,000 people. PWS is a complex condition that impacts nearly every system in the body. The hallmark symptom of PWS is hyperphagia, an unrelenting appetite and extreme hunger. A person with PWS never feels full.  There are currently no effective treatments to regulate appetite in PWS and individuals with PWS require a highly restricted environment to prevent life-threatening overeating and obesity.  Additional associated problems include growth hormone deficiency, behavioral challenges, intellectual disability, anxiety, sleep disturbances, and scoliosis. For many individuals with PWS, the elimination of hyperphagia would represent a critical advance, bringing new possibilities for an independent life.

About Foundation for Prader-Willi Research (FPWR)
FPWR is composed of thousands of parents, family members, researchers, and others who are interested in addressing the many issues related to PWS, including childhood obesity, developmental delays, psychiatric disorders, and autism spectrum disorders. The mission of FPWR is to eliminate the challenges of Prader-Willi syndrome through the advancement of research and therapeutic development. FPWR supports cutting edge research studies around the world to advance the understanding of PWS, and collaborates with research institutions, pharmaceutical companies and the FDA to advance new treatments that will help those with PWS.  To date, FPWR has funded over $10 million in PWS research.

Ovid Therapeutics Presents Additional Data and Analyses from the Phase 2 STARS Clinical Trial with OV101 for the Treatment of Angelman Syndrome at the 65th AACAP Annual Meeting

Additional Data and Analyses from the Phase 2 STARS Clinical Trial with OV101

Ovid Therapeutics Presents Additional Data and Analyses from the Phase 2
STARS Clinical Trial with OV101 for the Treatment of Angelman Syndrome at the
65th AACAP Annual Meeting

— Additional data and analyses suggest that in the OV101 15 mg once-daily dose group, changes in sleep parameters and motor domains contributed to the statistically significant improvement in overall clinical global symptoms (CGI-I) observed in previously announced topline data —

— Conference call and webcast today at 10:30 a.m. EDT during 65th American Academy of Child and Adolescent Psychiatry Annual Meeting —

SEATTLE, Oct. 25, 2018 (GLOBE NEWSWIRE) — Ovid Therapeutics Inc. (NASDAQ: OVID), a biopharmaceutical company committed to developing medicines that transform the lives of people with rare neurological diseases, today announced additional exploratory efficacy data and analyses from the company’s Phase 2 STARS trial that further support the potential of OV101, a novel selective extrasynaptic GABAA receptor agonist that is being investigated to treat Angelman syndrome. Angelman syndrome is a life-long genetic disorder that is characterized by a variety of signs and symptoms, and for which there are no FDA-approved medicines or an established treatment paradigm.

The additional efficacy data and analyses are being presented in a poster today at the American Academy of Child and Adolescent Psychiatry (AACAP) annual meeting by Alex Kolevzon, M.D., professor of psychiatry and pediatrics at the Icahn School of Medicine at Mount Sinai. The additional data and analyses revealed changes in certain sleep parameters and motor domains in both adults and adolescents in the OV101 15 mg once-daily dose group as further described in the detailed STARS data summary below. Ovid believes these observed changes may have contributed to the statistically significant improvement observed in the clinician-rated clinical global impressions of improvement (CGI-I) symptoms overall in the 15 mg once-daily OV101 dose group compared to placebo after 12 weeks of treatment, as reported in the topline data from the STARS trial on August 6, 2018. CGI-I is a global measure commonly used in clinical trials that allows the clinician to capture improvement in a constellation of clinical symptoms.

“Angelman syndrome is an extremely complex disorder in which any given patient may present with a variety of symptoms with different degrees of severity,” said Dr. Kolevzon. “These additional data from the STARS trial are encouraging, particularly the efficacy signals observed across the domains of sleep and motor, which appear to have driven the overall improvements seen in CGI-I. There are no established tools or endpoints to measure a drug’s effect on signs and symptoms of Angelman syndrome, and the information gained from the Phase 2 STARS trial establishes the potential of OV101 to offer a clinically meaningful benefit specific to people living with Angelman syndrome.”

“STARS was informed by extensive collaboration with the Angelman community,” said Jeremy Levin, DPhil, MB, BChir, chairman and chief executive officer of Ovid Therapeutics. “The data presented today contribute to a greater understanding and appreciation of the outcomes observed after administration of OV101 on key clinical aspects of Angelman syndrome. These results, together with those reported in August 2018, will help inform our discussions with the FDA when we meet with them later this year.”

Topline Data Announced August 6, 2018

Primary endpoint: Safety and Tolerability 
The study met its primary endpoint of safety and tolerability given that the adverse events (AEs) with OV101 treatment were similar to placebo treatment, with the majority of AEs being mild. OV101 showed a favorable risk profile and was well tolerated through 12 weeks of treatment. The most common AEs reported in the trial were vomiting, somnolence, irritability, aggression, and pyrexia. Serious adverse events (SAEs) of seizure were reported in two patients with a previous history of  seizures: one patient in the once-daily (QD) dose experienced a seizure and that was deemed unrelated to study drug; one patient experienced a seizure in the twice-daily (BID) dose group and that was assessed as possibly related to study drug by the investigator.

Exploratory endpoints:
The STARS trial explored the clinical utility of OV101 on changes in CGI-I, behavior, sleep, and gross and fine motor ability. The study randomized 88 patients and analyses were performed on 87 patients (mean age=22.6), which includes all patients who enrolled in the study and received at least one dose of study drug.

Prespecified analysis outcome
Following 12 weeks of treatment, OV101 showed a statistically significant improvement in CGI-I symptoms overall compared to placebo in a responder analysis (p=0.0206, combined dose group, Fisher’s Exact Test) and in the 15 mg QD dose group (p=0.0006, mixed model repeated measures (MMRM) analysis1 ).

Remaining prespecified analyses were conducted across subsets in the domains of behavior [Aberrant Behavior Checklist (ABC-C), Anxiety, Depression and Mood Scale (ADAMS)], sleep (e-diary – caregiver reported sleep changes) and motor [Modified Performance Oriented Mobility Assessment–Gait tool (mPOMA- G)], and analyses of these endpoints did not show a statistically significant difference from placebo.

Comprehensive Data Presented Today at AACAP

Results from Additional Exploratory Endpoints and Further Analyses of Domains of Sleep, Motor, Behavior and Quality of Life

Overall, the results indicate that OV101 seems to positively impact several relevant clinical features of Angelman syndrome (global functioning, sleep, motor disruption) and therefore support further clinical development of OV101 in Angelman syndrome.

Sleep Domain
Change from Baseline in Sleep Efficacy at Week 12 (MMRM Analysis)

An actigraphy watch was used to assess sleep parameters including latency to sleep, mean daytime sleepiness and changes in sleep efficiency. Approximately 45 percent (n=39) of patients tolerated the device. The clinician-rated clinical impression of sleep domain was analyzed using MMRM, to assess overall sleep. Sleep as reported by caregiver diary showed no changes.

Latency to Sleep Onset:

  • Latency to sleep onset (LSO) is the duration of time it takes a person to transition from full wakefulness to sleep. Sleep dysfunction has been identified as clinically relevant in Angelman syndrome, and the observed reduction in LSO may therefore be indicative of target engagement.
  • LSO was improved in OV101 15 mg QD dose group compared with placebo (Diff=-25.7 minutes, p=0.0147).

Mean Daytime Sleepiness and Sleep Efficiency:

  • Reduction in mean total sleep time during day (~50 minutes) and increase in sleep efficiency (3.65%) were seen in OV101 15 mg QD dose group compared with placebo.

Overall Sleep:

  • An improvement in clinical impression of sleep domain at Week 12 was observed in the OV101 15mg QD group compared to placebo (Diff=-0.77, p=0.0141). The OV101 BID group did not separate from placebo (Diff= -0.45, p=0.1407).

Gross and Fine Motor Domain
Change from Baseline in Motor Efficacy at Week 12 (MMRM Analysis)

Bayley Scales of Infant and Toddler Development Third Edition (BSID-III) was used to assess changes of ≥3 points from baseline (posthoc, responder analysis).

  • Changes in overall motor response (54%, p=0.0889; n=14/26) and gross motor only (36%, p=0.0522; n= 9/25) were observed in OV101 15 mg QD dose group compared to placebo at Week 12. No change was seen in fine motor ability alone with either dose.

PEDI-CAT mobility and daily activity summary score (post-hoc analysis)

  • Signals were observed in gross motor scores in OV101 15 mg QD group compared with placebo in: mobility score (0.91+/- 0.281 versus 0.08 +/- 0.294; mean +/- standard error (SE); per protocol set; p=0.0475), and in daily activity score (0.79 +/- 0.340 versus 0.00 +/- 0.300; per protocol set; p=0.0869).

Disability Index of CHAQ:

  • A signal (n=24, p=0.0704) was observed in the Disability Index of the Childhood Health Assessment Questionnaire (CHAQ) in the OV101 15 mg QD dose group compared to placebo.

ZenoTM Walkway:

  • Reduction in mean cadence (n=24, p=0.0340) and stride velocity (n=24, p=0.0406) was observed in the OV101 15 mg QD dose group compared to placebo.

Behavior Domain
In a post-hoc analysis, among patients who showed changes on the CGI-I, the Parent Global Impression (PGI) scale reported improvements in communication, challenging behavior, and anxiety. However, no significant differences were found on the ABC-C and ADAMS.

Quality of Life Domain
No changes were found between groups on EuroQoL 5-Dimension (EQ-5D-SL), Short-Form Health Survey (SF-36), or PGI.

Phase 2 STARS Trial Design
STARS was a 12-week, double-blind, placebo-controlled Phase 2 study. Eighty-eight patients (adults, n=66; adolescents, n=22) aged 13 to 49 years of age diagnosed with Angelman syndrome. The study randomized patients to one of three arms: once-daily (QD) dose of OV101 at night (15 mg), twice-daily (BID) dose of OV101 (10 mg in the morning and 15 mg at night), and placebo.

The primary endpoint of the trial was to assess the safety and tolerability of OV101 compared to placebo. The STARS trial also explored the clinical utility of OV101 on improvements in clinical global impressions, behavior, sleep, and gross and fine motor skills.

ELARA 1-year Extension Study
In the fourth quarter of 2018, Ovid expects to initiate ELARA, an open-label extension study that will enable individuals with Angelman syndrome who completed any prior OV101 study to be eligible to receive the investigational medicine. The study will use once-daily dosing and will assess long term safety and tolerability in addition to efficacy measures.

About Angelman Syndrome 
Angelman syndrome is a genetic disorder that is characterized by a variety of signs and symptoms. Characteristic features of this disorder include delayed development, intellectual disability, severe speech impairment, problems with movement and balance, seizures, sleep disorders and anxiety. The most common cause of Angelman syndrome is the loss of function of the gene that codes for ubiquitin protein ligase E3A (UBE3A), which plays a critical role in nerve cell communication, resulting in impaired tonic inhibition. Individuals with Angelman syndrome are highly social with a typical lifespan; however, they require constant support from a network of specialists and caregivers. Angelman syndrome affects approximately 1 in 12,000 to 1 in 20,000 people in the U.S. There are currently no U.S. Food and Drug Administration (FDA)-approved therapies for the treatment of Angelman syndrome.

Angelman syndrome is associated with a reduction in tonic inhibition, a function of the delta (δ)-selective GABAA receptor that allows a human brain to decipher excitatory and inhibitory neurological signals correctly without being overloaded. If tonic inhibition is reduced, the brain becomes inundated with signals and loses the ability to separate background noise from critical information.

About OV101
OV101 (gaboxadol) is believed to be the only delta (δ)-selective GABAA receptor agonist in development and the first investigational drug to specifically target the disruption of tonic inhibition, a central physiological process of the brain that is thought to be the underlying cause of certain neurodevelopmental disorders. OV101 has been demonstrated in laboratory studies and animal models to selectively activate the δsubunit of GABAA receptors, which are found in the extrasynaptic space (outside of the synapse), and thereby impact neuronal activity through tonic inhibition.

Ovid is developing OV101 for the treatment of Angelman syndrome and Fragile X syndrome to potentially restore tonic inhibition and relieve several of the symptoms of these disorders. In preclinical studies, it was observed that OV101 improved symptoms of Angelman syndrome and Fragile X syndrome. This compound has also previously been tested in over 4,000 patients (over 1,000 patient-years of exposure) and was observed to have favorable safety and bioavailability profiles.

The FDA has granted Orphan Drug and Fast Track designations for OV101 for both the treatment of Angelman syndrome and Fragile X syndrome. The U.S. Patent and Trademark Office has granted Ovid patents directed to methods of treating Angelman syndrome and Fragile X syndrome using OV101. The issued patents expire in 2035.

NEW YORK – August 6, 2018 – Ovid Therapeutics Inc. (NASDAQ: OVID), a biopharmaceutical company committed to developing medicines that transform the lives of people with rare neurological diseases, today announced that the Phase 2 STARS trial of OV101 achieved its primary endpoint of safety and tolerability. The investigational medicine showed a favorable safety profile and was well tolerated in adults and adolescents with Angelman syndrome. OV101 is the only selective extrasynaptic GABAA receptor agonist in development shown to mediate tonic inhibition, a key underlying pathophysiological mechanism of Angelman syndrome. Ovid’s founder, president and chief scientific officer, Matthew During, M.D., DSc,FACP, will present the data today at the 2018 Angelman Syndrome Foundation/Duplication15q Research Symposium in Chapel Hill, North Carolina.

The Phase 2 STARS international study is the first industry-sponsored, randomized, doubleblind,placebo-controlled clinical trial for Angelman syndrome. The study randomized 88 patients across three groups: a once-daily or twice-daily dose of OV101 or placebo. At the prespecified efficacy analysis at 12 weeks of treatment, OV101 showed a statistically significant improvement compared to placebo in the physician-rated clinical global impressions of improvement (CGI-I) – a measure commonly used in clinical trials that allows the physician to capture a constellation of clinical symptoms. CGI-I was ranked first in the topline statistical plan. Subsequent analyses in the hierarchy were conducted on a prespecified subset of scales across the domains of behavior, sleep and gait. While the analysis of these prespecified subsets did not show a statistically significant difference from placebo, full data analyses on these domains are ongoing and will be communicated in the future. Ovid intends to discuss these data with regulatory authorities to determine the next steps for a registrational pathway. Based on these data, the company plans to initiate in the fourth quarter of 2018 an open-label extension study (named ELARA); Angelman syndrome patients who completed any prior OV101 study may be eligible to receive the investigational medicine in this study.

Angelman syndrome is a rare, lifelong, genetic disorder that affects 1 in 15,000 people in the U.S. It is characterized by severe impairment in behavior, learning, verbal communication, motor skills, and sleep, and there are no FDA-approved medicines or an established treatment paradigm for this condition. If approved, OV101 could be the first medicine to specifically target a key underlying neurological dysfunction of Angelman syndrome — impaired tonic inhibition that is most commonly caused by a disruption of the UBE3A gene.

“We are excited by these data, as this is the first demonstration of positive clinical effect on overall symptomology in Angelman syndrome,” said Jeremy Levin, DPhil, MB, BChir, chairman and chief executive officer of Ovid Therapeutics. “In collaboration with the Angelman community, we designed a robust study to evaluate prespecified endpoints that may pave the way for a registrational pathway for a disorder that has no previously approved medicines. These data are a tribute to the patients and their families and we thank them.”

“These initial data from the STARS study are encouraging, particularly the statistically significant improvement in overall symptoms that we see in the CGI-I scale in the once-daily dosing group. Angelman syndrome is a complex disorder and the CGI-I scale captures the totality of global neurological deficits and helps to define the impact of medicines on the individual and their families,” said Ron Thibert, D.O., MsPH, chairperson, STARS clinical trial steering committee, director, Angelman syndrome clinic at Mass General Hospital for Children, and assistant professor at Harvard Medical School. “The data reported today are the first data in Angelman syndrome to show a compound specifically targeting the syndrome having a clinical effect. Ovid is the first company to have conducted a double-blind, placebo-controlled study in Angelman syndrome, providing important clinical and scientific data. Based on these data, I believe OV101 has the potential to offer a clinically meaningful benefit specific to people living with Angelman syndrome.”

“The STARS study was designed to provide information to allow us to progress the development of OV101,” said Amit Rakhit, M.D., MBA, chief medical and portfolio management officer of Ovid Therapeutics. “With these findings, we have advanced our understanding of relevant endpoints to evaluate key symptoms of Angelman syndrome. Furthermore, we demonstrated that a once-daily dose of OV101 could be sufficient to drive clinically meaningful benefit to patients. We look forward to discussing the data with regulatory authorities to inform our future development plans.”

STARS Phase 2 Topline Data Summary and Design
STARS was a 12-week, double-blind, placebo-controlled Phase 2 study. Eighty-eight patients (adults, n=66; adolescents, n=22) aged 13 to 49 years of age diagnosed with Angelman syndrome were randomized at 13 clinical trial sites in the U.S. and Israel. The study randomized patients to one of three arms: once-daily (QD) dose of OV101 at night (15mg), twice-daily (BD) dose of OV101 (10mg in the morning and 15mg at night), and placebo.

The intent to treat (ITT) population was 88 patients. A modified intent to treat (mITT) analysis of 87 patients (mean age = 22.6), which includes any patient who enrolled in the study and received at least one dose of study drug, was performed to evaluate the efficacy endpoints.

The primary endpoint of the trial was to assess the safety and tolerability of OV101 compared to placebo. The STARS trial explored the clinical utility of OV101 on improvements in clinical global impressions, maladaptive behavior, sleep, and gross and fine motor skills.

Primary Endpoint: Safety and Tolerability Data
The study met its primary endpoint of safety and tolerability given that the adverse events (AEs) with OV101 treatment were similar to placebo treatment, with the majority of AEs being mild. OV101 showed a favorable risk profile and was well tolerated through 12 weeks of treatment. Overall, the data are consistent with the favorable risk profile observed in previous insomnia trials with this investigational medicine.

The most common AEs reported in the trial were vomiting, somnolence, irritability, aggression, and pyrexia.

Table 1: Most Frequent Adverse Events*

Table 1: Most Frequent Adverse Events

Events occurring in greater than 5 percent (two or more patients) compared to placebo in either treatment arm included pyrexia, rash, seizure, enuresis and myoclonic epilepsy.

Adverse Events Occurring More Frequently in OV101 Arms vs. Placebo

Serious adverse events (SAEs) of seizure were reported in two patients: one patient in the QD dose experienced a seizure and that was deemed unrelated to study drug; one patient experienced a seizure in the BID dose group and that was assessed as possibly related to study drug by the investigator.

Treatment discontinuations due to adverse events were low. One patient in the placebo arm discontinued compared to no patients and three patients in the once-daily dose group and twicedaily dose group, respectively.

  • Placebo arm: one patient with irritability
  • Twice-daily arm: one patient with myoclonus; one patient with seizure, and one patient with irritability/anxiety/sleep disorder

Efficacy Endpoint Data
At 12 weeks of treatment, the first prespecified efficacy endpoint (CGI-I) demonstrated a robust and statistically significant difference (p=0.0206; Fisher’s Exact test) between the combined OV101 treatment arms and placebo. This reflects an improvement in two-thirds of the combined treatment groups versus one-third in placebo.

In the prespecified analysis using the rigorous Mixed Model Repeated Measures (MMRM), which evaluated each OV101 treatment arm independently against placebo, the difference in CGI-I mean score at 12 weeks was statistically significant (p=0.0006) in the once-daily OV101 group versus placebo and also in the combined OV101 treatment group versus placebo (p=0.0103).

In a post-hoc analysis of patients who were “much” or “minimally” improved having a CGI-I score of ≤3, the data suggest that younger patients who received a once-daily dose had the greatest response to OV101 compared to older age groups.

Ovid Therapeutics plans to present the full clinical data from the STARS study at an upcoming medical meeting.

ELARA 1-year Extension Study
In the fourth quarter of 2018, Ovid expects to initiate ELARA, an open-label extension study that will enable individuals with Angelman syndrome who completed any prior OV101 study to be eligible to receive the investigational medicine. The study will use once-daily dosing and will assess long term safety and tolerability in addition to efficacy measures.

Ovid Therapeutics has created a website specifically to provide disease education on Angelman syndrome. Learn more at anglemansyndrome.com.

About Angelman Syndrome
Angelman syndrome is a genetic disorder that is characterized by a variety of signs and symptoms. Characteristic features of this disorder include delayed development, intellectual disability, severe speech impairment, problems with movement and balance, seizures, sleep disorders and anxiety. The most common cause of Angelman syndrome is the loss of function of the gene that codes for ubiquitin protein ligase E3A (UBE3A), which plays a critical role in nerve cell communication, resulting in impaired tonic inhibition. Individuals with Angelman syndrome are highly social with a typical lifespan; however, they require constant support from a network of specialists and caregivers. Angelman syndrome affects approximately 1 in 15,000 people in the U.S. There are currently no U.S. Food and Drug Administration (FDA)-approved therapies for the treatment of Angelman syndrome.

Angelman syndrome is associated with a reduction in tonic inhibition, a function of the delta (δ)- selective GABAA receptor that allows a human brain to decipher excitatory and inhibitory neurological signals correctly without being overloaded. If tonic inhibition is reduced, the brain becomes inundated with signals and loses the ability to separate background noise from critical information.

About OV101
OV101 (gaboxadol) is believed to be the only delta (δ)-selective GABAA receptor agonist in development and the first investigational drug to specifically target the disruption of tonic inhibition, a central physiological process of the brain that is thought to be the underlying cause of certain neurodevelopmental disorders. OV101 has been demonstrated in laboratory studies and animal models to selectively activate the δ-subunit of GABAA receptors, which are found in the extrasynaptic space (outside of the synapse), and thereby impact neuronal activity through tonic inhibition.

Ovid is developing OV101 for the treatment of Angelman syndrome and Fragile X syndrome to potentially restore tonic inhibition and relieve several of the symptoms of these disorders. In preclinical studies, it was observed that OV101 improved symptoms of Angelman syndrome and Fragile X syndrome. This compound has also previously been tested in over 4,000 patients (over 1,000 patient-years of exposure) and was observed to have favorable safety and bioavailability profiles.

The FDA has granted Orphan Drug and Fast Track designations for OV101 for both the
treatment of Angelman syndrome and Fragile X syndrome. The U.S. Patent and Trademark Office has granted Ovid patents directed to methods of treating Angelman syndrome and Fragile X syndrome using OV101. The issued patents expire in 2035.

Designation of Unique ICD-10 Code for Angelman Syndrome
19 Jun

Designation of Unique ICD-10 Code for Angelman Syndrome

Availability of Dedicated Code Will Advance Research and Development of Treatments for this Unique, Well-defined Syndrome and Lead to Improved Clinical Care

Nashville, TN, June 19, 2018 — The Angelman Biomarkers and Outcome Measures (A-BOM) Alliance today announced that the National Center for Health Statistics has designated a specific ICD-10 code for Angelman syndrome, a neurodevelopmental disorder caused by genetic mutations. The designation of the ICD-10 code resulted from a combined effort of the A-BOM Alliance, leaders in the biopharmaceutical industry, family physicians, specialists, pharmacists and other health professionals. The new ICD-10 code (Q93.51) will take effect on October 1, 2018.

Until now, Angelman syndrome was included in the ICD-10 code Q93.5, which contains a large group of disorders with different genetic causes and different treatment strategies and is not specific to Angelman syndrome. The dedicated ICD-10 code for Angelman syndrome will make it easier for the field to conduct epidemiologic research and retrospective studies, determine true prevalence and morbidity and mortality rates, recruit patients for clinical trials, track outcomes of clinical interventions, and develop protocols for standard of care.

“We are grateful to everyone who joined with A-BOM to make the new ICD-10 code a reality, including the clinicians who contributed their expertise, and the companies and foundations that provided funding and letters of support,” said Terry Jo V. Bichell, MPH, Ph.D., director and scientific officer of the A-BOM Alliance. “The designation of a unique ICD-10 code for Angelman syndrome is a significant development that will lead to improved clinical care for patients with this disorder. What a difference one number will make!” 

The ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list from the World Health Organization (WHO). ICD-10 codes are used to document an individual’s medical condition for epidemiology, research, health insurance billing and reimbursement, and administration. The United States uses the ICD-10-CM, a Clinical Modification of the WHO standard, while Europe and other parts of the world use the ICD-10.

“Ovid would like to congratulate everyone involved in the successful effort to designate a unique ICD-10 code for Angelman syndrome,” said Jeremy Levin, DPhil, MB, BChir, chairman and chief executive officer of Ovid Therapeutics. “This is an important development for the field and we were pleased to lend our support. With clinical trials of investigational therapeutics under way, a dedicated ICD-10 code will help healthcare professionals better understand the impact of the illness, track outcomes of clinical interventions, and fully identify the patient population that could benefit.”
