Nitric Oxide Therapeutics Platform

Nitric Oxide

NO is recognized as a vital molecule involved in many physiological and pathological processes. NO is naturally produced by the body’s immune system to provide a first line of defense against invading pathogens. It is a powerful molecule with a short half-life of a few seconds in the blood, enabling it to be cleared rapidly from the body. NO has been shown to play a critical role in the function of several body systems. For example, as vasodilator of smooth muscles, NO enhances blood flow and circulation. In addition, NO is involved in regulation of a wound healing and immune responses to infection. The pharmacology, toxicity and other data for NO in humans is generally well known, and its use has been approved by the FDA in a number of therapeutic applications, mainly as a vasodilator.

Nitric Oxide & Infection

NO has multiple immunoregulatory and antimicrobial functions that are likely to be of relevance to inhaled NO therapy. In vitro studies suggest that NO possesses anti-microbial activity against common bacteria, gram positive and gram negative, as well as mycobacteria, fungi, yeast, parasites and helminthes. It has the potential to eliminate multi-drug resistant strains of the above. Anti-viral activity covers respiratory viruses such as influenza, corona viruses, RSV and others. In healthy humans, NO has been shown to stimulate muccocilary clearance, and low levels of nasal NO correlate with impaired muccociliary function in the human upper airway. Unlike other inhaled drugs, NO is also a smooth muscle relaxant and avoids the concomitant bronchial constriction often associated with inhaled antibiotics and muccolytics. In addition to treating CF infections, this suggests that NO may be useful in directly treating the mucus caused by CF, which is the principal manifestation of the disease.

Development Status

We have completed a phase 1 clinical safety trial on ten healthy humans. In addition, we acquired positive human clinical data on over 50 patients with Cystic Fibrosis (CF), RSV (Bronchiolitis) and Non Tuberculosis Mycobacterium (NTM). These data show not only that our product is safe, but also suggest effectivity.

Our combined product of drug and device is a revolutionary respiratory targeted system designed to safely and effectively deliver 160 ppm NO (Nitric Oxide) to non-intubated patients (home or hospital) in order to treat severe lung infections.

We plan to continue clinical trials and enter the market in Israel, the US and EU for NTM and RSV, with launches for both planned in 2022 through 2024. In addition, we plan to commence clinical trials for our fourth indication, Chronic Obstructive Pulmonary Disease (COPD), with a market potential that exceeds the first 3 indications –its launch in the market is expected after the launch of NTM and bronchiolitis.

With our Orphan indications (NTM, CF) combined with prior familiarity with the drug, NO, we expect fast track to regulatory approvals.
