On December 3, 2024 Beyond Cancer, Ltd., a clinical-stage biotechnology company developing ultra-high concentration nitric oxide (UNO) as an immunotherapeutic for solid tumors, reported that the Israeli Ministry of Health (IMOH) has approved the use of Low Volume UNO (LV UNO) in a Phase 1b clinical trial of LV UNO in combination with anti-PD-1 therapy (Press release, Beyond Cancer, DEC 3, 2024, View Source [SID1234648763]). The trial will be conducted at four sites in Israel and patient screening will begin in the first quarter of 2025.

The Phase 1b trial (NCT05351502) is a clinical proof-of-concept trial that will assess the intratumoral administration of LV UNO in patients with unresectable cutaneous or subcutaneous histologically confirmed primary or metastatic lesions, who have shown disease progression or prolonged stable disease ( 12 weeks) after receiving a single agent anti-PD-1 containing treatment. The trial, which is expected to enroll up to 20 subjects, is designed to assess the preliminary efficacy of LV UNO by objective response rate (ORR) and duration of response (DOR) per RECIST v1.1 and secondarily immune-related response via iRECIST. Safety and tolerability of LV UNO in combination with anti-PD-1 therapy, as well as its potential to enhance the type, density, and distribution of immune cells within the tumor microenvironment will also be observed. Topline data from the Phase 1b portion of the study are anticipated in the second half of 2025.
"We are excited to initiate the Phase 1b trial of LV UNO, a potentially groundbreaking solid tumor treatment approach, in combination with PD-1 inhibitors," said Dr. Jedidiah Monson, Chief Medical Officer of Beyond Cancer. "In preclinical studies, a single dose of UNO has been shown to increase PD-L1 expression and improve overall survival in animal models compared to anti-PD-1 alone. Further, Phase 1a human data that demonstrated immune system activation were presented at ASCO (Free ASCO Whitepaper)’s Key Opinion Leader Event held in June 2024. We look forward to the Phase 1b trial results to establish the basis of further investigation of UNO in combination with PD-1 inhibitors."
"The initiation of the Phase 1b trial represents a major step forward in our vision for personalized cancer treatment. We see UNO as a complementary therapy for future cancer treatment paradigms, particularly for patients with anti-PD-1 refractory or resistant disease, potentially offering more patients access to effective treatment," stated Dr. Selena Chaisson, Chief Executive Officer, and Director of Beyond Cancer.
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.
