ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider carefully the risks described below, together with the other information included or incorporated by reference in this Annual Report. If any of the following risks occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected. In these circumstances, the market price of our common stock could decline. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our business, prospects, financial condition and results of operations.

Risks Related to Our Financial Position and Capital Requirements

We have incurred significant losses since our inception and anticipate that we will continue to incur losses for the foreseeable future. We are a clinical-stage company. We have no approved products and have generated no revenue to date and may never generate revenue or achieve profitability.

Our ability to implement our business strategy is subject to numerous risks that you should be aware of before making an investment decision. These are not the only risks we face. These risks include, among others, that:

Because of the numerous risks and uncertainties associated with drug development and commercialization, we are unable to accurately predict the timing or amount of expenses or when, or if, we will be able to achieve profitability. If we are required by regulatory authorities to perform studies in addition to those expected or if there are any delays in the initiation and completion of our clinical trials or the development of any of our product candidates, our expenses could increase.

It is highly likely that we will need to raise additional capital to meet our business requirements in the future, and such capital raising may be costly or difficult to obtain, and could dilute current stockholders’ ownership interests.

Our future capital requirements will depend on many factors, including the progress and results of our clinical trials, the timing and outcome of regulatory review of our product candidates, commercial manufacturing success, the number and development requirements of other product candidates that we pursue, and the costs of commercialization activities, including product marketing, sales, and distribution. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to reasonably estimate the amounts of additional capital outlays and operating expenditures that our business will require. It is likely that we will need to raise additional funds through public or private debt or equity financings to meet various objectives including, but not limited to:

Any additional capital raised through the sale of equity or equity-linked securities may dilute our current stockholders’ ownership in us and could also result in a decrease in the market price of our common stock. The terms of those securities issued by us in future capital transactions may be more favorable to new investors and may include preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect.

Furthermore, any debt or equity financing that we may need may not be available on terms favorable to us, or at all.

Additionally, we may incur substantial costs in pursuing future capital financing, including investment banking fees, legal fees, accounting fees, securities law compliance fees, printing and distribution expenses and other costs. We may also be required to recognize non-cash expenses in connection with certain securities we issue, such as convertible notes and warrants, which may adversely impact our financial condition.

If we are unable to obtain required additional capital, we may have to curtail our growth plans or cut back on existing business, and we may not be able to continue operating if we do not generate sufficient revenues from operations needed to stay in business.

Risks Related to the Discovery and Development of Our Product Candidates

We are heavily dependent on the success of our product candidates, which are in the early stages of clinical development. We cannot give any assurance that any of our product candidates will receive certification or regulatory approval, which is necessary before they can be commercialized. We cannot give any assurance that any of our product candidates will receive regulatory approval, which is necessary before they can be commercialized.

To date, we have invested substantially all of our efforts and financial resources to design and develop our product candidates, including conducting clinical trials and providing general and administrative support for these operations. Our future success is dependent on our ability to successfully develop, obtain regulatory certification or approval for, and then successfully commercialize one or more product candidates. Our future success is dependent on our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize one or more product candidates. We currently generate no revenue from sales of any product, and we may never be able to develop or commercialize a marketable product.

Two of our product candidates are in the early stages of development and will require additional clinical development (and in some cases additional preclinical development), management of nonclinical, clinical and manufacturing activities, regulatory certification or approval, obtaining adequate manufacturing supply, building of a commercial organization and significant marketing efforts before we generate any revenue from product sales. To date, we have conducted 3 pilot clinical trials involving 198 patients with bronchiolitis (mainly caused by RSV) and a pilot clinical trial in nine patients with CF. In addition, Rambam healthcare campus in Israel conducted a compassionate treatment for two patients with CF who suffer from NTM infections (specifically M. abscessus). Abscessus). All of these trials were conducted outside the U.S. and were not conducted pursuant to an FDA IND. The results of these trials demonstrated improvements in various endpoints and clinical outcomes. The results of these three studies showed improvements in various endpoints and clinical outcomes. The trials were small, however, and it is likely that the FDA will view them as not significant because of their size and scope. In addition, the delivery systems were different from the one that we intend to test and market, subject to FDA approval, in the U.S., further reducing the likelihood that FDA would view these test results as adequate or sufficient to support marketing applications. Two pilot clinical trials are ongoing, one in viral pneumonia and one in NTM lung infection. Both of these studies are using our LungFit^® system (PRO and GO, respectively) and are being conducted outside the United States. Once completed, if the data are favorable, these trials would support our efforts towards obtaining FDA approval. We therefore intend to conduct larger clinical trials aiming for statistically and clinically significant favorable results, or we will not be able to obtain regulatory certification nor approval to market such product candidates. We therefore intend to conduct larger clinical trials aiming for statistically and clinically significant favorable results, or we will not be able to obtain regulatory approval to market our product candidates. It may be years before a pivotal trial is initiated, if at all, for such product candidates. It may be years before a pivotal study is initiated, if at all. Before a medical device clinical trial can be undertaken in the U.S., the sponsor of the trial must submit an IDE application for a medical device and the FDA must permit the trial to go forward. We cannot assure that we will obtain such agency acquiescence in a timely manner, or at all.

In addition, we cannot be sure that we will be successful in completing the development of our NO Delivery System to the satisfaction of the FDA, which could lead to material delays in our ability to commence U.S.-based clinical trials, if at all. We are not permitted to market or promote any of our product candidates before we receive certification or regulatory approval from the FDA or comparable foreign regulatory authorities and notified bodies, and we may never receive such certification or regulatory approval for any of our product candidates. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates.

We as a company have submitted our first marketing application for approval of our LungFit^® PH product candidate to the FDA and approval is pending, but we can make no assurances as to what FDA shall decide or any other comparable foreign regulatory authorities and notified bodies where we are seeking regulatory approval; although in 2014 the FDA granted us orphan drug designation for the use of NO in the treatment of CF and in 2015, the EU also granted us orphan drug designation for the use of NO in the treatment of CF. We are no longer pursuing the drug regulatory pathway, so the orphan drug designation may have no application. We cannot be certain that any of our product candidates will be successful in clinical trials or receive certification or regulatory approval. We cannot be certain that any of our product candidates will be successful in clinical studies or receive regulatory approval. Further, our product candidates may not receive certification or regulatory approval even if they are successful in clinical trials. Further, our product candidates may not receive regulatory approval even if they are successful in clinical studies. If we do not receive certification or regulatory approvals for our product candidates, we may not be able to continue our operations. If we do not receive regulatory approvals for our product candidates, we may not be able to continue our operations. Even if we do receive FDA approval for our LungFit^® PH product candidate, the indications for which we are initially seeking approval are very narrow and this, as a result, may limit their commercial viability.

We generally plan to seek certification or regulatory approval to commercialize our product candidates in the U.S., the EU and in additional foreign countries. To obtain certification or regulatory approvals we must comply with the numerous and varying regulatory requirements of such countries regarding safety, efficacy, chemistry, manufacturing and controls, clinical trials, commercial sales, pricing and distribution of our product candidates. To obtain regulatory approvals we must comply with the numerous and varying regulatory requirements of such countries regarding safety, efficacy, chemistry, manufacturing and controls, clinical studies, commercial sales, pricing and distribution of our product candidates. Even if we are successful in obtaining marketing certification or regulatory approval in one jurisdiction, we cannot ensure that we will obtain certification or regulatory approval in any other jurisdictions. If we are unable to obtain clearance or approval for our product candidates in multiple jurisdictions, our revenue and results of operations would be negatively affected. If we are unable to obtain approval for our product candidates in multiple jurisdictions, our revenue and results of operations would be negatively affected.

The success of our business may also depend upon our ability to identify, license or discover additional product candidates.

Although a substantial amount of our effort will focus on the continued clinical testing, potential certification, regulatory approval and commercialization of our existing product candidates, the success of our business may also depend upon our ability to identify, license or discover additional product candidates. Our research programs or licensing efforts may fail to yield additional product candidates for clinical development for a number of reasons, including but not limited to the following:

If any of these events occur, we may be forced to abandon our development efforts for a program or programs, or we may not be able to identify, license or discover additional product candidates, which would have a material adverse effect on our business and could potentially cause us to cease operations. Research programs to identify new product candidates require substantial technical, financial and human resources. We may focus our efforts and resources on potential programs or product candidates that ultimately prove to be unsuccessful.

The certification or regulatory approval processes of the FDA and comparable foreign regulatory authorities and notified bodies are lengthy, time consuming and inherently unpredictable. If we are ultimately unable to obtain certification or regulatory approval for our product candidates, our business will be substantially harmed. If we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.

The time required to obtain certification or regulatory approval by the FDA or notified bodies in Europe is unpredictable, typically takes many years following the commencement of clinical trials and depends upon numerous factors. In addition, certification or regulatory approval policies, regulations or the type and amount of clinical data necessary to gain certification or regulatory approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions, which may cause delays in the certification or regulatory approval or the decision not to certify or approve an application. We have not obtained certification or regulatory approval for any product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain certification or regulatory approval. We have not obtained regulatory approval for any product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain regulatory approval.

The process required by the FDA before a new medical device may be marketed in the U.S. generally involves the following:

An IDE application is a request for authorization from the FDA to administer an investigational medical device to humans. We currently do not have any IDEs in effect.

Clinical trials involve the administration of the medical device to human subjects under the supervision of qualified investigators in accordance with current Good Clinical Practices (“GCPs”) which include the requirement that all research subjects provide their informed consent for participation in any clinical trial. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IDE. Additionally, approval must also be obtained from each clinical trial site’s Institutional Review Board (“IRB”) before the trials may be initiated, and the IRB must monitor the study until completed and re-assess and approve the study at least annually. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

Clinical trials for medical devices are usually conducted in two phases. Pilot clinical trials are normally conducted in small groups of patients to assess safety, find the optimal dosing range and assess potential efficacy. After a successful pilot study or studies, the device is administered to a population of patients large enough to meet the requirements for regulatory approval. This size of trial is usually multi-center, controlled and potentially double-blind.

During the course of a clinical trial, we are required to inform the FDA and the IRB about adverse events associated with our product candidate. The FDA, the IRB, or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee, or DSMB. This group reviews unblinded data from clinical trials and provides authorization for whether a trial may move forward at designated check points based on access to certain data from the study. We may also suspend or terminate a clinical trial based on evolving business objectives or competitive climates. Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed investigational medical device information is submitted to the FDA in the form of an PMA requesting approval to market the product for one or more indications. The application includes all relevant data available from pertinent preclinical and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things.

Once the PMA submission has been accepted for filing, the FDA’s goal is to review applications within six months of filing. However, the review process is often significantly extended by FDA requests for additional information or clarification as well as pandemic related delays. However, the review process is often significantly extended by FDA requests for additional information or clarification. The FDA may refer the application to an advisory committee for review, evaluation, and recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it typically follows such recommendations.

An IDE is a request for authorization from the FDA to administer an investigational medical device to humans. We currently do not have any IDEs in effect.

Applications for our product candidates could fail to receive regulatory approval for many reasons, including but not limited to the following:

This lengthy certification or regulatory approval process, as well as the unpredictability of the results of clinical studies, may result in our failing to obtain certification or regulatory approval to market any of our product candidates, which would significantly harm our business, results of operations and prospects.

Our business and eventual sale of our product candidates are subject to extensive regulatory requirements, including compliance with labelling, manufacturing and reporting controls. If we fail or are unable to timely obtain the necessary 510(k) clearances, de-novo authorizations, or premarket approval, or PMA, approvals for new products, or equivalent steps in third countries including the EEA, our ability to generate revenue could be materially harmed.

Our product candidates are classified as medical devices and are subject to extensive regulation in the United States by the FDA and other federal, state and local authorities and by comparable foreign regulatory authorities. The FDA can delay, limit or deny 510(k) clearance or PMA approval of a device for many reasons, including:

● we may not be able to demonstrate to the FDA’s satisfaction that our systems are safe and effective for its intended use;

● the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where required;

● the manufacturing process or facilities we use or contract to use may not meet applicable requirements; and

● disruptions at the FDA caused by funding shortages or global health concerns, including the COVID-19 pandemic.

The FDA may refuse our requests for 510(k) clearance, de-novo or PMA of new products, new intended uses or modifications to existing products.

From time to time, legislation is drafted and introduced in the United States that could significantly change the statutory provisions governing any regulatory approval or clearance that we receive in the United States. In addition, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions which may prevent or delay approval or clearance of our test kits under development or impact our ability to modify our currently approved or cleared test kits on a timely basis.

Our products are also subject to approval, certification and regulation by foreign regulatory and safety agencies. For example, the EU has adopted the EU MDR, which imposes stricter requirements for the marketing and sale of medical devices, including in the area of clinical evaluation requirements, quality systems and post-market surveillance. Complying with the requirements of the EU MDR may require us to incur significant expenditures. Failure to meet these requirements could adversely impact our business in the EEA and other regions that tie their product registrations to the EU requirements.

Once commercialized, modifications to our marketed products may require new 510(k) clearances or approval of PMA supplements, or equivalent steps in third counties including the EEA, or may require us to cease marketing or recall the modified products until certifications, clearances or regulatory approvals are obtained.

Modifications to any of our products once they are commercialized may require new regulatory approvals or clearances, including 510(k) clearances or approval of PMA supplements, or require us to recall or cease marketing the modified systems until these clearances or approvals are obtained. The FDA requires device manufacturers to initially make and document a determination of whether or not a modification requires a new approval, supplement or clearance. A manufacturer may determine that a modification could not affect safety or efficacy and does not represent a major change in its intended use, so that no new clearance or approval is necessary. However, the FDA can review a manufacturer’s decision and may disagree. The FDA may also on its own initiative determine that a new clearance or approval of a PMA Supplement is required. We may make modifications in the future that we believe do not or will not require additional clearances or approvals. If the FDA disagrees and requires new clearances or approvals for the modifications, we may be required to recall and to stop marketing our products as modified, which could require us to redesign our products and/or seek new marketing authorizations and harm our operating results. In these circumstances, we may be subject to significant enforcement actions.

For example, if a manufacturer determines that a modification to a PMA approved device could affect its safety or effectiveness or would constitute a major change in its intended use, then the manufacturer must file for a new a new PMA or approval of a PMA supplement. Where we determine that modifications to our products require a new PMA approval, we may not be able to obtain those additional approvals for the modifications or additional indications in a timely manner, or at all. Obtaining new approvals can be a time-consuming process, and delays in obtaining required future approvals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our future growth.

For those products sold in the EEA, we must notify our EU notified body if significant changes are made to the products or if there are substantial changes to our quality assurance systems affecting those products. Obtaining certification can be a time-consuming process, and delays in obtaining required future clearances or approvals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our future growth.

Medical device development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies may not be predictive of future study results.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical study process. The results of preclinical studies and early clinical studies of our product candidates may not be predictive of the results of later-stage clinical studies. Product candidates that have shown promising results in early-stage clinical studies may still suffer significant setbacks in subsequent advanced clinical studies. There is a high failure rate for medical devices proceeding through clinical studies, and product candidates in later stages of clinical studies may fail to show the desired safety and efficacy traits despite having progressed satisfactorily through preclinical studies and initial clinical studies. A number of companies in the medical device and biopharmaceutical industry have suffered significant setbacks in advanced clinical studies due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier studies. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses. We do not know whether any pivotal studies we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain certification or regulatory approval to market our product candidates. We do not know whether any pivotal studies we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain regulatory approval to market our product candidates. Nor do we know whether the FDA will permit us to proceed directly to pivotal trials without performing pilot trials in the U.S. using the same delivery system that we will seek approval by the agency.

If we or our suppliers fail to comply with ongoing FDA or other foreign regulatory authority requirements, or if we experience unanticipated problems with our products, these products could be subject to restrictions or withdrawal from the market.

Once we obtain certification or marketing authorization for our product candidates, any product for which we obtain certification, clearance or approval, and the manufacturing processes, post-market surveillance, post-approval clinical data and promotional activities for such product, will be subject to continued regulatory review, oversight, requirements, and periodic inspections by the FDA and other domestic and foreign regulatory and notified bodies. We must comply with equivalent standards in third countries.

In particular, we and our suppliers are required to comply with FDA’s QSR in the U.S. and other regulations enforced outside the United States which cover the manufacture of our products and the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of medical devices. Regulatory bodies, such as the FDA, and notified bodies enforce the QSR in the U.S. and other regulations through periodic inspections. The failure by us or one of our suppliers to comply with applicable statutes and regulations administered by the FDA, or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions:

If any of these actions were to occur it would harm our reputation and cause our product sales and profitability to suffer and may prevent us from generating revenue. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory requirements which could result in our failure to produce our products on a timely basis and in the required quantities, if at all. Furthermore, if our suppliers fail to meet contractual requirements and we are unable to secure one or more replacement suppliers capable of production at a substantially equivalent cost, our clinical studies may be delayed or we could lose potential revenue.

In addition, we are required to conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products, and we must comply with medical device reporting requirements, including the reporting of adverse events and malfunctions related to our products. For example, the FDA has issued to us a post-market surveillance order under Section 522 of the FDCA which requires that we conduct a human factors study, as well as conduct a detailed analysis of adverse events and complaints from home users. Later discovery of previously unknown problems with our products, including unanticipated adverse events or adverse events of unanticipated severity or frequency, manufacturing problems, or failure to comply with regulatory requirements such as QSR, may result in changes to labeling, restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects.

In addition, we may be required to conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products in the EEA. We must comply with medical device reporting requirements, including the reporting of adverse events and malfunctions related to our products. Later discovery of previously unknown problems with our products, including unanticipated adverse events or adverse events of unanticipated severity or frequency, manufacturing problems, or failure to comply with regulatory requirements may result in changes to labeling, restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, suspension of regulatory clearances or approvals, product seizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects.

Our products may cause or contribute to adverse medical events or be subject to failures or malfunctions that we are required to report to the FDA, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, financial condition and results of operations. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us.

Once commercialized, we will be subject to the FDA’s medical device reporting regulations and similar foreign regulations, which require us to report to the FDA when we receive or become aware of information that reasonably suggests that one or more of our products may have caused or contributed to a death or serious injury or malfunctioned in a way that, if the malfunction were to recur, it could cause or contribute to a death or serious injury. The timing of our obligation to report is triggered by the date we become aware of the adverse event as well as the nature of the event. We may fail to report adverse events of which we become aware within the prescribed timeframe. We may also fail to recognize that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of the product. If we fail to comply with our reporting obligations, the FDA could take action, including warning letters, untitled letters, administrative actions, criminal prosecution, imposition of civil monetary penalties, revocation of our device clearance or approval, seizure of our products or delay in clearance or approval of future products.

The FDA and comparable foreign regulatory authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture of a product or in the event that a product poses an unacceptable risk to health. The FDA’s authority to require a recall must be based on a finding that there is reasonable probability that the device could cause serious injury or death. We may also choose to voluntarily recall a product if any material deficiency is found. A government-mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, malfunctions, manufacturing defects, labeling or design deficiencies, packaging defects or other deficiencies or failures to comply with applicable regulations. Product defects or other errors may occur in the future.

Depending on the corrective action we take to redress a product’s deficiencies or defects, the FDA may require, or we may decide, that we will need to obtain new clearances or approvals for the device before we may market or distribute the corrected device. Seeking such clearances or approvals may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our devices, we may face additional regulatory enforcement action, including FDA warning letters, product seizure, injunctions, administrative penalties or civil or criminal fines.

Companies are required to maintain certain records of recalls and corrections, even if they are not reportable to the FDA. We may initiate voluntary withdrawals or corrections for our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, it could require us to report those actions as recalls and we may be subject to enforcement action. A future recall announcement could harm our reputation with customers, potentially lead to product liability claims against us and negatively affect our sales. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital, will distract management from operating our business and may harm our reputation and financial results.

All manufacturers placing medical devices on the market in the EEA are legally bound to report to the relevant competent authorities (a) any serious incident involving devices made available on the EU market, except expected side-effects which are clearly documented in the product information and quantified in the technical documentation and are subject to trend reporting, and (b) any field safety corrective action in respect of devices made available on the EU market, including any field safety corrective action undertaken in a third country in relation to a device which is also legally made available on the EU market, if the reason for the field safety corrective action is not limited to the device made available in the third country. Reports should be submitted through the electronic system set up and managed by the EU commission in collaboration with EEA countries. Report of serious incidents will be automatically transmitted to the competent authority of the EEA country in which the incident occurred and reports on field safety corrections actions will be automatically transmitted to the competent authority of the EEA country in which the field safety corrective action is being or is to be undertaken and the EEA country in which the manufacturer has its registered place of business.

Under the EU MDR, a ’serious incident’ means any incident that directly or indirectly led, might have led or might lead to any of the following: (a) the death of a patient, user or other person; (b) the temporary or permanent serious deterioration of a patient’s, user’s or other person’s state of health; or (c) a serious public health threat. A ‘field safety corrective action’ means corrective action taken by a manufacturer for technical or medical reasons to prevent or reduce the risk of a serious incident in relation to a device made available on the market.

Malfunction of our products could result in future voluntary corrective actions, such as recalls, including corrections, or customer notifications, or agency action, such as inspection or enforcement actions. If malfunctions do occur, we may be unable to correct the malfunctions adequately or prevent further malfunctions, in which case we may need to cease manufacture and distribution of the affected products, initiate voluntary recalls, and redesign the products. Regulatory authorities may also take actions against us, such as ordering recalls, imposing fines, or seizing the affected products. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results.

Our product candidates may in the future be subject to product recalls that could harm our reputation, business and financial results.

Medical devices can experience performance problems in the field that require review and possible corrective action. The occurrence of component failures, manufacturing errors, software errors, design defects or labeling inadequacies affecting a medical device could lead to a government-mandated or voluntary recall by the device manufacturer, in particular when such deficiencies may endanger health. The FDA requires that certain classifications of recalls be reported to the FDA within 10 working days after the recall is initiated. Companies are required to maintain certain records of recalls, even if they are not reportable to the FDA. We may initiate voluntary recalls involving our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, they could require us to report those actions as recalls. Product recalls may divert management attention and financial resources, expose us to product liability or other claims, harm our reputation with customers and adversely impact our business, financial condition and results of operations.

We may be subject to regulatory or enforcement actions if we engage in improper marketing or promotion of our product candidates.

Our educational and promotional activities and training methods must comply with FDA and other applicable laws, including the prohibition of the promotion of a medical device for a use that has not been cleared or approved by the FDA. Use of a device outside of its cleared or approved indications is known as “off-label” use. Physicians may use our products off-label in their professional medical judgment, as the FDA does not restrict or regulate a physician’s choice of treatment within the practice of medicine. However, if the FDA determines that our educational and promotional activities or training constitutes promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of warning letters, untitled letters, fines, penalties, injunctions, or seizures, any of which could have an adverse impact on our reputation and financial results.

It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our educational and promotional activities or training methods to constitute promotion of an off-label use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could be damaged, and adoption of the products could be impaired. Although our policy is to refrain from statements that could be considered off-label promotion of our products, the FDA or another regulatory agency could disagree and conclude that we have engaged in off-label promotion. It is also possible that other federal, state or foreign enforcement authorities might take action, including, but not limited to, through a whistleblower action under the FCA, if they consider our business activities constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal, civil or administrative penalties, treble damages, fines, disgorgement, exclusion from participation in government healthcare programs, reporting requirements and compliance oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations. In addition, the off-label use of our products may increase the risk of product liability claims. Product liability claims are expensive to defend and could divert our management’s attention, result in substantial damage awards against us, and harm our reputation.

The advertising and promotion of our products in the EEA is subject to EEA countries’ national laws implementing Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other national legislation of individual EEA country governing the advertising and promotion of medical devices. EEA country legislation may also restrict or impose limitations on our ability to advertise our products directly to the general public. In addition, voluntary EU and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with healthcare professionals.

Legislative or regulatory reforms may make it more difficult and costly for us to obtain regulatory clearance or approval of any future products and to manufacture, market and distribute our products after clearance or approval is obtained.

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulatory approval, manufacture and marketing of regulated products or the reimbursement thereof. In addition, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval or clearance of our future products under development or impact our ability to modify our currently cleared products on a timely basis. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of planned or future products. It is impossible to predict whether legislative changes will be enacted or FDA regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be.

FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new statutes, regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of any future products or make it more difficult to obtain clearance or approval for, manufacture, market or distribute our products. We cannot determine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future. Such changes could, among other things, require: additional testing prior to obtaining clearance or approval; changes to manufacturing methods; recall, replacement or discontinuance of our products; or additional record keeping.

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be promulgated that could prevent, limit or delay regulatory clearance or approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. For example, the recent change in administration may impact our business and industry. Any change in the laws or regulations that govern the clearance and approval processes relating to our current, planned and future products could make it more difficult and costly to obtain clearance or approval for new products or to produce, market and distribute existing products. Significant delays in receiving clearance or approval or the failure to receive clearance or approval for any new products would have an adverse effect on our ability to expand our business. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing clearance that we may have obtained and we may not achieve or sustain profitability.

In addition, on May 25, 2017, the new EU MDR entered into force for medical devices marketed in the EEA. Implementation of the EU MDR was delayed by one year due to the COVID-19 pandemic. Following its entry into application on May 26,2021, the EU MDR introduced substantial changes to the obligations with which medical device manufacturers must comply in the EEA. High risk medical devices are subject to additional scrutiny during the conformity assessment procedure. Specifically, the EU MDR repeals and replaces the EU Medical Devices Directive. Unlike directives, which must be implemented into the national laws of the European Economic Area (EEA) Member States, the regulations is directly applicable, i.e., without the need for adoption of EEA country laws implementing them, in all EEA countries and are intended to eliminate current differences in regulation of medical devices among EEA countries. The EU MDR, among other things, is intended to establish a uniform, transparent, predictable and sustainable regulatory framework across the EEA for medical devices to ensure a high level of safety and health while supporting innovation. The EU MDR entered into application on May 26, 2021 and among other things:

The EU MDR imposes a number of new requirements on manufacturers of medical devices. Notified bodies need to be accredited by the EU Member States’ accreditation bodies to conduct assessment procedures for medical devices in accordance with the Regulation. There are currently a relatively small number of notified bodies that have been accredited to conduct these assessments. This may delay conformity assessment procedures in the future in the EU. This may impact our activities in the EEA and the UK, the renewal of our existing CE Certificates of Conformity and conformity assessment related to future bodies.

Further, the EU MDR imposes increased compliance obligations for us to access the EEA market. Our failure to comply with applicable foreign regulatory requirements, including those administered by authorities of the EEA countries, could result in enforcement actions against us, including refusal, suspension, variation, or withdrawal of our CE Certificates of Conformity by our EU notified body, which could impair our ability to market products in the EEA in the future. Any changes to the membership of the EU, such as the recent departure of the United Kingdom (Brexit), may impact the regulatory requirements for the impacted countries and impair our business operations and our ability to market products in such countries.

Brexit, has created significant uncertainty concerning the future relationship between the UK and the EU. On 24 December 2020, the EU and UK reached an agreement in principle on the framework for their future relationship, the EU-UK Trade and Cooperation Agreement. The Agreement primarily focuses on ensuring free trade between the EU and the UK in relation to goods. The Agreement does not however, specifically address medical devices. The Agreement seeks to ensure that the parties ensure “regulatory cooperation”. Among the changes that will now occur are that Great Britain (England, Scotland and Wales) will be treated as a third country. Northern Ireland will, with regard to EU regulations, continue to follow the EU regulatory rules. In light of the fact that the CE marking process is set out in EU law, which no longer applies in the UK, the UK has devised a new route to market culminating in a UK Conformity Assessed (UKCA) mark to replace the CE mark. Northern Ireland will, however, continue to be covered by the regulations governing CE marks. As part of the Agreement, the EU and the UK have agreed to continue to recognize declarations of conformity based on a self-assessment in the other territory. Given the lack of comparable precedent to Brexit, it is unclear what the financial, regulatory, and legal implications of Brexit will be and how it will affect us. However, potentially changing regulatory schemes and tariffs engendered by Brexit may add additional complexity, cost and delays in marketing or selling our products in the United Kingdom.

We are working on NTM lung infection which is very rare.

NTM lung infection is a very rare disease and only a small number of people suffer from this condition. As a result of these small numbers, we may not be able to complete the study related to NTM or, even if approved, the device for that indication may never be profitable. As a result of these small numbers, we may not be able to complete the study related to NTM Abscessus or, even if approved, the device for that indication may never be profitable.

We are working on bronchiolitis in infants that usually is caused by the RSV virus.

RSV is a seasonal virus (only in the winter). In our trial, we are heavily dependent on the occurrence and the severity of this virus. Treating for RSV is highly reliant on the weather conditions in winter. The weather in the winter is not predictable. For example, if the winter is warm or short, or the RSV infection was not severe enough when we conducted our trial, or the length of stay in the hospital at the year that trial was conducted was different from previous seasons, then we might miss the season or the results can be significantly different between two seasons or between different countries or even between different sites.

We are working on PPHN which is a highly competitive market and certification or regulatory approval may not be easily obtained.

A delivery system with a generator of NO has never been approved anywhere in the world and this may cause significant delays in the approval process.

Clinical trials may be necessary to support future product submissions to the FDA. The clinical trial process is lengthy and expensive with uncertain outcomes, and often requires the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. Delays or failures in our clinical trials will prevent us from commercializing any modified or new products and will adversely affect our business, operating results and prospects.

Initiating and completing clinical trials necessary to support any future PMAs, and additional safety and efficacy data beyond that typically required for a 510(k) clearance, for our possible future product candidates, will be time-consuming and expensive and the outcome uncertain. Moreover, the results of early clinical trials are not necessarily predictive of future results, and any product we advance into clinical trials may not have favorable results in later clinical trials. The results of preclinical studies and clinical trials of our products conducted to date and ongoing or future studies and trials of our current, planned or future products may not be predictive of the results of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Our interpretation of data and results from our clinical trials do not ensure that we will achieve similar results in future clinical trials. In addition, preclinical and clinical data are often susceptible to various interpretations and analyses, and many companies that have believed their products performed satisfactorily in preclinical studies and earlier clinical trials have nonetheless failed to replicate results in later clinical trials. Products in later stages of clinical trials may fail to show the desired safety and efficacy despite having progressed through nonclinical studies and earlier clinical trials. Failure can occur at any stage of clinical testing. Failure can occur at any time during the clinical study process. Our clinical studies may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical and no
