(1) In December 2020 and January 2021, the Company sold pre-funded warrants to purchase up to 5,238,043 and 2,420,910 shares of common stock, respectively. The shares of common stock associated with the pre-funded warrants are considered outstanding for the purposes of computing earnings per share prior to exercise because the shares may be issued for little or no consideration, are fully vested, and are exercisable after the original issuance date. The pre-funded warrants sold in December 2020 and January 2021 were exercised during the period and included in the denominator for the period of time the warrants were outstanding.

The following outstanding potentially dilutive securities have been excluded from the calculation of diluted net loss per share for the periods presented due to their anti-dilutive effect:
