GARDEN CITY, N.Y., March 17, 2026 (GLOBE NEWSWIRE) -- Beyond Cancer, Ltd., a clinical stage biotechnology company developing ultra-high concentration nitric oxide (UNO) as an investigational immunotherapeutic for solid tumors and subsidiary of Beyond Air, Inc. (NASDAQ: XAIR), today announced early signs of clinical activity and a favorable safety and tolerability profile from its Phase 1 clinical trial evaluating a single intratumoral UNO injection administered as monotherapy. These data were included in an Online Itinerary Planner issued today for the American Association for Cancer Research (AACR) Annual Meeting 2026, which is scheduled to be held from April 17-22, 2026 at the San Diego Convention Center in San Diego, California.

The Phase 1 trial (NCT05351502) was a clinical proof-of-concept trial that assessed the intratumoral administration of UNO in patients with unresectable cutaneous or subcutaneous histologically confirmed primary or metastatic lesions. The trial enrolled ten heavily pretreated patients, including breast cancer (n=6), squamous cell carcinoma (n=2), and melanoma (n=2). Patients received a mean of 5.5 prior systemic therapies and 10.3 total cancer-directed treatments. Six patients received 25,000 ppm UNO and four patients received 50,000 ppm UNO.

As of October 1, 2025, seven of ten patients remain alive between 19 to 37 months following a single UNO injection. One patient died of disease progression 25 months after treatment. Two patients with triple negative breast cancer have no evidence of disease. No deaths occurred within 12 weeks after treatment. Treatment demonstrated a favorable safety and tolerability profile, with most treatment‑related adverse events limited to Grade 1. One treatment-related serious adverse event (hypoxia) occurred during administration at 25,000 ppm; the event was not considered dose-limiting and resolved fully.

“The combination of favorable safety and tolerability and early clinical activity strengthen our belief that UNO could serve as a differentiated complement to anti‑PD‑1 therapy in metastatic disease and perhaps as monotherapy prior to metastases,” said Steve Lisi, Chief Executive Officer of Beyond Air. “The duration of survival in this end-stage, heavily pre-treated population is compelling, and we look forward to future studies to better understand the potential of UNO therapy.”

The poster presentation at AACR will include data from an updated analysis of the ongoing Phase 1 trial beyond what is reflected in the published abstract referenced in this release.

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 Cancer, Ltd.
Beyond Cancer, Ltd. 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.

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 and CE Mark 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 revolutionary 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).

Additionally, 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. For more information, visit www.beyondair.net.

Forward Looking Statements
This press release contains “forward-looking statements” concerning the potential safety, tolerability and efficacy of inhaled nitric oxide and the ultra-high concentration nitric oxide product candidate, as well as its therapeutic potential in a number of indications; and the potential impact on patients and anticipated benefits associated with inhaled nitric oxide and the ultra-high concentration nitric oxide product candidate. Forward-looking statements include, but are not limited to, statements regarding the potential safety, tolerability, efficacy and therapeutic potential of ultra-high concentration nitric oxide (UNO”); the significance of interim clinical data from Beyond Cancer’s Phase 1 trial; the potential for UNO to be studied as a monotherapy, in combination with anti-PD-1 therapy, or in earlier lines of treatment; the expected content and timing of the AACR presentation; and the development, clinical, regulatory, and commercial prospects of Beyond Cancer’s and Beyond Air’s product candidates. Forward-looking statements may be identified by words such as “aim,” “anticipate,” “believe,” “could,” “expect,” “goal,” “intend,” “look,” “may,” “plan,” “potential,” “project,” “target,” “will,” “would,” and similar expressions, or the use of future tense or conditional constructions (such as “will,” “may,” “could,” “should” and the like) and by the fact that these statements do not relate strictly to historical or current matters. Rather, forward-looking statements relate to anticipated or expected events, activities, trends or results as of the date they are made. Because forward-looking statements relate to matters that have not yet occurred, many of which are outside the control of Beyond Air or Beyond Cancer, these statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from any future results expressed or implied by the forward-looking statements.

Many factors could cause actual activities or results to differ materially from the activities and results anticipated in forward-looking statements, including risks related to the ability to raise additional capital; the timing and results of future pre-clinical studies and clinical trials; the potential that regulatory authorities, including the FDA and comparable non-U.S. regulatory authorities, may not grant or may delay approval for our product candidates; the approach to discover and develop novel drugs, which is unproven and may never lead to efficacious or marketable products; the ability to fund and the results of further pre-clinical studies and clinical trials of our product candidates; obtaining, maintaining and protecting intellectual property utilized by products; obtaining regulatory approval for products; competition from others using similar technology and others developing products for similar uses; dependence on collaborators; and other risks, which may, in part, be identified and described in the “Risk Factors” section of Beyond Air’s most recent Annual Report on Form 10-K and other of its filings with the Securities and Exchange Commission, all of which are available on Beyond Air’s website.
