Developing medical device products, including conducting clinical studies, if required, and establishing manufacturing capabilities, requires substantial funding. Additional financing may be required to fund the research and development of our medical device product candidates. We have not generated any product revenues, and do not expect to generate any revenues until, and only if, we develop such products, and receive clearance from FDA to sell our product candidates in the U.S. and receive product clearance from other regulatory authorities to sell our product candidates internationally.
We may not have the resources to complete the development and commercialization of any of our proposed product candidates. We may require additional financing to further the clinical development of our product candidates. In the event that we cannot obtain such financing, we will be unable to complete the development necessary to make submissions to FDA for 510(k) premarket clearance. This will delay or require termination of research and development programs, clinical studies, material characterization studies, and regulatory processes, which could have a materially adverse effect on our business.
The amount of capital we may need will depend on many factors, including the progress, timing and scope of our research and development programs; the progress, timing and scope of our clinical studies, if required; the time and cost necessary to obtain regulatory clearance; the time and cost necessary to establish our own marketing capabilities or to seek marketing partners; the time and cost necessary to respond to technological and market developments; changes made or new developments in our existing collaborative, licensing and other commercial relationships; and new collaborative, licensing and other commercial relationships that we may establish.
Until we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings, or corporate collaboration and licensing arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. In addition, we could be forced to discontinue product development and reduce or forego attractive business opportunities. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates, or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.
Our fixed expenses, such as rent and other contractual commitments, will likely increase in the future, as we may enter into leases for new facilities and capital equipment and/or enter into additional licenses and collaborative agreements. Therefore, if we fail to raise substantial additional capital to fund these expenses, we could be forced to cease operations, which could cause you to lose all of your investment.
