Based on our ability to raise funds through the ATM Program and its cash, cash equivalents and marketable securities as of December 31, 2022, we have concluded that it is probable that such proceeds would provide sufficient additional capital to meet our operating, debt service and capital requirements for the next twelve months following the date of this Annual Report.

In January 2018, the FDA granted LUMRYZ orphan drug designation for the treatment of narcolepsy, which makes LUMRYZ potentially eligible for certain development and commercial incentives, including potential U.S. market exclusivity for up to seven years. Additionally, thirteen LUMRYZ-related U.S. patents have been issued, and there are additional patent applications currently in development and/or pending at the U.S.
In June 2023, we announced the U.S. commercial launch of LUMRYZ for the treatment of cataplexy or EDS in adults living with narcolepsy . Numerous LUMRYZ-related U.S. patents have been issued having expiration dates spanning from mid-2037 to early-2042, and there are additional patent applications currently in development and/or pending at the U.S.
Our lead product candidate, LUMRYZ, also known as FT218, is an investigational once-at-bedtime, extended-release formulation of sodium oxybate for the treatment of cataplexy or excessive daytime sleepiness (“EDS”) in adults with narcolepsy. We are primarily focused on obtaining final U.S. FDA approval of LUMRYZ and the launch of LUMRYZ, if approved.
LUMRYZ is an extended-release formulation of sodium oxybate indicated to be taken once at bedtime for the treatment of cataplexy or EDS in adults with narcolepsy. As of the date of this Annual Report, LUMRYZ is the only commercialized product in our portfolio. We continue to evaluate opportunities to expand our product portfolio .
