XERS 2021 Annual Report

Trade Secrets and Other Protection In addition to patented intellectual property, we also rely on trade secrets and proprietary know-how to protect our technology and maintain our competitive position, especially when we do not believe that patent protection is appropriate or can be obtained. Our policy is to require each of our employees, consultants and advisors to execute a confidentiality and inventions assignment agreement before beginning their employment, consulting or advisory relationship with us. The agreements generally provide that the individual must keep confidential and not disclose to other parties any confidential information developed or learned by the individual during the course of the individual’s relationship with us except in limited circumstances. These agreements generally also provide that we own all inventions conceived and/or reduced to practice by the individual in the course of their employment with us or rendering services to us. Other Intellectual Property Rights We file trademark applications and pursue registrations in the United States and abroad when appropriate. We own registered trademarks for the mark Xeris Pharmaceuticals in the U.S., for the marks GVOKE, GVOKE HYPOPEN and HYPOPEN in the US and several ex-US countries, the registered trademark for OGLUO in the EU and the UK, and the registered trademarks for XERISOL and XERIJECT in Australia, the EU and the UK. We also own pending trademark applications for XERISOL and XERIJECT in the U.S. and a number of ex-US countries, and for the marks GVOKE and GVOKE HYPOPEN in a number of ex-U.S. countries, all for use in connection with our pharmaceutical research and development and products, as well as trade names that could be used with our product candidates. From time to time, we may find it necessary or prudent to obtain licenses from third-party intellectual property holders. Regulation Government Regulation United States Drug and Biological Product Development In the United States, the FDA regulates drugs, medical devices and combinations of drugs and devices, or combination products, under the FDCA and its implementing regulations and biologics under the FDCA and the Public Health Service Act ("PHSA") and their implementing regulations. Drugs, biologics, medical devices and combination products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, requests for voluntary product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. Certain of our products and product candidates are subject to regulation as combination products, which means that they are composed of both a drug product and device product. If our drug products, along with our combination product, marketed individually, each component would be subject to different regulatory pathways and reviewed by different centers within the FDA. A combination product, however, is assigned to a center that will have primary jurisdiction over its regulation based on a determination of the combination product’s primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of Gvoke and some of our product candidates, the primary mode of action is attributable to the drug component of the product, or biological component of the product, which means that the FDA’s Center for Drug Evaluation and Research ("CDER") or FDA’s Center for Biologics Evaluation and Research ("CBER") has primary jurisdiction over the premarket development, review and approval of the combination product. Accordingly, we plan to continue to investigate our products through the IND framework and seek approval through the NDA or BLA pathway. Based on our discussions with the FDA to date, we do not anticipate that the FDA will require a separate medical device authorization for the device component of our combination products, but this could change during the course of its review of any marketing application that we may submit. The process required by the FDA before a drug or biologic may be marketed in the United States generally involves the following: 20
