Beyond Air® Licenses Commercial Rights to Selective Neuronal Nitric Oxide Synthase (nNOS) Inhibitors for the Treatment of Autism Spectrum Disorder from Hebrew University of Jerusalem


Hebrew University’s preclinical results recently published in Advanced Science show a reversal of the molecular, synaptic and behavioral autism spectrum disorder (ASD) phenotypes

Plan to initiate a first-in-human clinical trial of nNOS for treatment of ASD in 2025

Conference call at 4:30 PM ET today, June 15, 2023


GARDEN CITY, N.Y., June 15, 2023 (GLOBE NEWSWIRE) — Beyond Air, Inc. (NASDAQ: XAIR) (“Beyond Air” or the “Company”), a commercial stage medical device and biopharmaceutical company focused on harnessing the power of endogenous and exogenous nitric oxide (NO) to improve the lives of patients suffering from respiratory illnesses, neurological disorders and solid tumors (through its affiliate Beyond Cancer, Ltd.), today announced that it has entered into an agreement with Yissum Research Development Company of the Hebrew University of Jerusalem, LTD. to license the commercial rights for multiple neuronal nitric oxide synthase (nNOS) inhibitor candidates, currently being developed for the treatment of autism spectrum disorder (ASD) and other neurological conditions. There are currently no therapies approved by the U.S. Food and Drug Administration (FDA) specifically for the treatment of ASD.

“We are the world’s leading developer of nitric oxide based therapies, as evidenced by FDA approval of our LungFit PH to treat term and near-term neonates with hypoxic respiratory failure (“persistent pulmonary hypertension of the newborn” or “PPHN”), our robust pipeline of revolutionary LungFit systems in clinical trials for the treatment of various severe lung infections using inhaled NO, the development of ultra-high concentration NO to treat solid tumors through Beyond Cancer, and now the development of nNOS inhibitors to treat autism,” stated Steve Lisi, Chairman and Chief Executive Officer of Beyond Air. “The results of groundbreaking preclinical studies conducted by Dr. Haitham Amal of the Hebrew University suggest a direct link between NO and ASD, which may lead to the first therapy to reverse ASD behavioral deficits. We are pleased to have entered into this partnership and look forward to initiating a planned first-in-human study in 2025.”

“This is an exciting novel approach to treating ASD. The partial inhibition of nNOS reduces nitrosative stress biomarkers and reverses the molecular, synaptic and behavioral ASD-associated phenotypes. Confirming these results in humans should be expedited,” commented Dr. Amal.

Dr. Amal is an Assistant Professor at the Institute for Drug Research, Faculty of Medicine at the Hebrew University of Jerusalem. He began his academic journey at the age of seventeen, with a degree in Pharmacy, from the Hebrew University. From there he moved to Tel Aviv University for his master’s degree in neuropharmacology in the Faculty of Medicine. His PhD was conducted at the Technion Institute of Technology in Israel. Dr. Amal started his work on ASD and Alzheimer’s disease at MIT in 2015. At MIT, the first paper of his postdoctoral research was published in the Journal of Molecular Psychiatry – the leading journal in Psychiatry. Dr. Amal’s research has been widely published, with more than 30 publications on cancer, autism, Alzheimer’s disease, and other brain disorders; he has been the recipient of many awards including from the Wolf Foundation. Dr. Amal is a member of many local and international scientific committees and societies. 

Under the terms of the agreement, Beyond Air will pay the Hebrew University of Jerusalem, LTD. fees associated with certain pre-clinical, clinical, regulatory and sales milestones. Additionally, the Company will pay a low single digit royalty on net sales.

At normal physiological levels, NO production and degradation are balanced and involved in normal cell signaling and in regulating numerous physiological functions. At higher concentrations, however, NO produced via nNOS becomes toxic and can lead to abnormal cell signaling and cell death. This dysregulation of nNOS may be responsible for various neurodevelopmental, neuropsychiatric, and neurodegenerative disorders including ASD.

Dr. Haitham Amal’s lab at the Hebrew University of Jerusalem conducted multidisciplinary comprehensive experiments using cellular and mouse models, as well as clinical samples and human induced pluripotent stem cells (iPSCs) to investigate the role of NO in ASD. To establish if NO leads to biochemical and cellular ASD-like phenotypes, C57BL/6J wild-type (WT) male mice were treated with an NO donor, S-nitroso-N-acetyl penicillamine (SNAP). The study demonstrated, biochemically and behaviorally, that treating WT mice with a NO donor led to an ASD-like phenotype. To determine the involvement of NO in ASD, the study inhibited NO production pharmacologically in the Shank3 mouse (M1) model. For this purpose, M1 mice were treated with a nNOS inhibitor, 7-nitroindazole (7-NI). The Cntnap2(-/-) mutant mouse (M2) model was also used. Like the M1 model, the M2 mice were treated with 7-NI. The results showed that pharmacological intervention with a neuronal NO synthase inhibitor in both models led to a reversal of the molecular, synaptic, and behavioral ASD-associated phenotypes.

Additionally, the study showed that treating human iPSC-derived cortical neurons from patients with SHANK3 mutations with the nNOS inhibitor showed similar therapeutic effects.

This innovative work suggests that NO may play a significant role in ASD development and suggests a novel strategy for an effective treatment. These important findings have unlocked a new pathway to examine NO in diverse mutations on the spectrum, as well as in other neurodevelopmental disorders and psychiatric diseases.

The pre-clinical research, funded by HUJI, was published in Advance Science on May 22, 2023 and can be found here.

About Autism Spectrum Disorder (ASD)

ASD is a serious neurodevelopmental and behavioral disorder, and one of the most disabling conditions and chronic illnesses in children. ASDs include a wide range of developmental disorders that share a core of neurobehavioral deficits manifested by abnormalities in social interactions, deficits in communication, restricted interests, and repetitive behaviors. In 2023, the CDC reported that approximately 1 in 36 children in the U.S. is diagnosed with an ASD. On average, ASD costs an estimated $60,000 a year through childhood, with the bulk of the costs in special services and lost wages related to increased demands on one or both parents. Mothers of children with ASD, who tend to serve as the child’s case manager and advocate, are less likely to work outside the home. On average, they work fewer hours per week and earn 56 percent less than mothers of children with no health limitations and 35 percent less than mothers of children with other disabilities or disorders. The cost of caring for Americans with autism reached $268 billion in 2015 and is expected to rise to $461 billion by 2025 in the absence of more-effective interventions and support across the life span. 

About Beyond Air®, Inc.
Beyond Air is a medical device and biopharmaceutical company dedicated to harnessing the power of nitric oxide through its revolutionary NO Generator and Delivery System, LungFit, that uses NO generated from ambient air to deliver precise amounts of NO to the lungs for the potential treatment of a variety of pulmonary diseases. LungFit can generate up to 400 ppm of NO, for delivery either continuously or for a fixed amount of time and has the ability to either titrate dose on demand or maintain a constant dose. The Company has received FDA approval for its first system, LungFit PH, for persistent pulmonary hypertension of the newborn. Beyond Air is currently advancing its other revolutionary LungFit systems in clinical trials for the treatment of severe lung infections such as viral community-acquired pneumonia (including COVID-19), nontuberculous mycobacteria (NTM) and severe lung infections in other settings. Additionally, Beyond Cancer, an affiliate of Beyond Air, is investigating ultra-high concentrations of NO with a proprietary delivery system to target certain solid tumors in the pre-clinical setting.
