Beyond Cancer™ Presents Positive First-in-Human Clinical Data for Ultra-High Concentration Nitric Oxide (UNO) Therapy in Solid Tumors During the Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting


First-in-human Phase 1 study demonstrates early clinical proof of concept

Positive clinical biomarker data demonstrate evidence of immune system activation and the translation of the immunogenic response previously observed in preclinical studies

Data represent the first successful administration of intratumoral UNO therapy


Additional Phase 1 data for UNO expected in 2024

GARDEN CITY, N.Y. and HAMILTON, Bermuda, Nov. 03, 2023 (GLOBE NEWSWIRE) — Beyond Cancer, Ltd., an affiliate of Beyond Air, Inc. (NASDAQ: XAIR) that is developing ultra-high concentration nitric oxide (UNO) as an immunotherapeutic for solid tumors, today announced encouraging first-in-human and first-in-class clinical data demonstrating a promising safety profile and clear evidence of immune system activation via biomarker response. The single agent treatment in relapsed or refractory unresectable, primary or metastatic cutaneous and subcutaneous malignancies represents an unprecedented use of ultra-high concentration nitric oxide as an immunotherapeutic. These data were presented today at the Society for Immunotherapy of Cancer (SITC) Annual Meeting 2023, which is being held in San Diego, California from November 1st to 5th via a poster presentation of abstract number 733.

“The development of immunotherapy has pushed the frontier of cancer medicine further than ever expected,” stated Dr. Jedidiah Monson, Chief Medical Officer. “Beyond Cancer is thrilled to contribute to this rapidly evolving landscape with a straightforward, minimally invasive procedure that may very well become a part of the immunotherapeutic armamentarium.”

The Company’s abstract presented at SITC includes safety, tolerability, biomarker and initial antitumor activity results from 5 subjects dosed with 25,000 ppm UNO. The data show UNO at 25,000 ppm delivered over 5-minutes upregulates cytotoxic T-cells, T-central memory cells, M1 macrophages, and dendritic cells while downregulating T-regulatory cells and mononuclear-myeloid-derived suppressor cells (M-MDSC).

Specifically, by Day 21, a single UNO administration resulted in an immunostimulatory effect. Dendritic cells increased more than 250%, representing more than a 2-fold increase in the magnitude observed in a murine model utilizing 50,000 ppm UNO. In addition, more than a 150% increase in T-central memory cells was observed, consistent with previously reported murine data (Sela Y et al. AACR/NCI/EORTC 2023). Encouragingly, there was also a greater than 50% increase in M1 macrophages over the same time period.

UNO also had a favorable impact on the inhibitory cells of the immune system. T-regulatory cells decreased by 40% by Day 21 and myeloid derived suppressor cells (M-MDSC) decreased by greater than 30% by Day 7.

Dr. Frederick Dirbas, Head of the Beyond Cancer Scientific Advisory Board, commented, “Prior preclinical data convincingly demonstrated immunostimulatory and anti-tumor effects of UNO compared to control in mice. To see the same immunostimulatory effects from preclinical studies carry over to humans is an important milestone in assessing the potential anti-tumor effects of UNO in humans.”

Of the five heavily pre-treated patients treated as of this data cut, UNO was well tolerated with primarily Grade 1 related toxicities observed with an early clinical response (Day 7) in a highly refractory, salvage population.       

The poster presentation detailing the emerging early clinical data titled, “Phase 1 study of ultra-high concentration nitric oxide (UNO) in relapsed or refractory, unresectable, primary, or metastatic cutaneous and subcutaneous malignancies,“ at the SITC 2023 Annual Meeting will be made available on the company’s website (click here).

About Beyond Cancer, Ltd.
Beyond Cancer, Ltd., an affiliate of Beyond Air, Inc., is a development-stage biopharmaceutical and medical device company utilizing ultra-high concentration nitric oxide (UNO) via a proprietary delivery platform to treat primary tumors and prevent metastatic disease. Nitric oxide at ultra-high concentrations has been reported to show anticancer properties and to potentially serve as a chemosensitizer and radiotherapy enhancer. A first-in-human study is underway in patients with solid tumors. The Company is conducting preclinical studies of UNO in multiple solid tumor models to inform additional treatment protocols. The company’s Scientific Advisory Board (SAB) includes several prominent key opinion leaders in oncology including Dr. Fred Dirbas, Assoc. Prof. of Surgery, Div. of Surgical Oncology, Stanford University School of Medicine, Dr. Sunil Panchal, President of the National Institute of Spine and Pain, and Dr. Mark Pegram, Susy Yuan-Huey Hung Professor of Medicine (Oncology), Medical Director, Clinical Translational Research Unit, and Associate Dean for Clinical Research Quality at Stanford University.

About Nitric Oxide
Nitric Oxide (NO) is a potent molecule, naturally synthesized in the human body, proven to play a critical role in a broad array of biological functions. In the airways, NO targets the vascular smooth muscle cells that surround the small resistance arteries in the lungs. Currently, exogenous inhaled NO is used in adult respiratory distress syndrome, post certain cardiac surgeries and persistent pulmonary hypertension of the newborn to treat hypoxemia. Additionally, NO is believed to play a key role in the innate immune system and in vitro studies suggest that NO possesses anti-microbial activity not only against common bacteria, including both gram-positive and gram-negative, but also against other diverse pathogens.

About UNO Therapy for Solid Tumors
Cancer is the second leading cause of death globally, with tumor metastases responsible for approximately 90% of all cancer-related deaths. Current cancer treatment modalities generally include chemotherapy, immunotherapy, radiation, and/or surgery. Ultra-high concentration Nitric Oxide (UNO) therapy is a completely new approach to preventing relapse or metastatic disease. In vitro murine data show that local tumor ablation with UNO stimulates an anti-tumor immune response in solid tumor cancer models. Beyond Cancer, Ltd. believes that UNO has the potential to prevent relapse or metastatic disease with as little as a single 5-minute treatment and with limited toxicity or off-target effects.

About Beyond Air®, Inc.
Beyond Air is a commercial stage medical device and biopharmaceutical company dedicated to 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. The Company has received FDA approval for its first system, LungFit® PH for the treatment of term and near-term neonates with hypoxic respiratory failure. Beyond Air is currently advancing its other LungFit systems in clinical trials for the treatment of severe lung infections such as viral community-acquired pneumonia (including COVID-19), and nontuberculous mycobacteria (NTM). The Company has also partnered with The Hebrew University of Jerusalem to advance a pre-clinical program dedicated to the treatment of autism spectrum disorder (ASD) and other neurological disorders. Beyond Cancer, Ltd., 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.
