Thereafter, on August 20, 2020, the board of directors granted 21,112 stock options to the same individuals with a grant date fair value of $12.81 per share. There were 3,959 stock option grants that were considered vested on the grant date. The effects of the stock option modifications resulted in $20,900 of stock compensation expense allocable to general and administrative for the three months ended March 31, 2021.

All granted shares that are canceled, forfeited, or expired are returned to the 2017 Plan and are available for grant in conjunction with the issuance of new common stock awards. Restricted stock units (“RSUs”) vest over a specified amount of time or when certain performance metrics are achieved by the Company. In the three months ended March 31, 2022 and 2021, the fair value of the shares of common stock underlying restricted stock units was determined by the closing stock price listed on the Nasdaq Capital Market on the grant date. The following table summarizes the activity for all RSUs outstanding at March 31 under the 2017 Plan: 2022 2021 Weighted Average Weighted Average Grant Date Grant Date Fair Value Fair Value Shares Per Share Shares Per Share Nonvested RSUs at beginning of year, as restated 510,851 $ 12.48 946,245 $ 12.81 Granted — — 6,019 9.00 Vested (2,947) 8.71 — — Cancelled and forfeited (334,271) 12.81 — — Nonvested RSUs at March 31, 173,633 $ 11.91 952,264 $ 12.79 Subsequent to the issuance of the December 31, 2021 consolidated financial statements, the Company identified an error related to the calculation of the number of vested shares of restricted stock units related to the Company’s 2017 Equity Incentive Plan. The Company used an incorrect number of vested shares of restricted stock units for the year ended December 31, 2021. Accordingly, the Company restated the number of vested shares of restricted stock units for the year ended December 31, 2021 from 37,802 shares to 393,909 shares, and the resulting total non-vested restricted stock units at December 31, 2021 from 866,958 shares to 510,851 shares. Additionally, the weighted average grant date fair value of vested shares for the year ended December 31, 2021 was restated from $6.51 per share to $11.21 per share, and the weighted average grant date fair value for total nonvested restricted stock units as of December 31, 2021 was restated from $12.16 per share to $12.48 per share. This change did not have any impact on our earnings per share calculations, nor did it have any impact on any previous disclosures related to potentially dilutive securities excluded from the computations of diluted weighted-average shares of common stock outstanding. The Company has evaluated the materiality of this error and concluded that it is not material to the December 31, 2021 consolidated financial statements. Further, the Company will also prospectively restate the previously reported financial information for the related error in future and annual filings for the year ending December 31, 2022. Total stock compensation expense recognized from stock-based compensation awards classified as restricted stock units were recognized in the condensed consolidated statements of operations for the three months ended March 31, 2022 and 2021, as follows: Three Months Ended March 31, 2022 2021 Research and development $ 12,000 $ 267,700 General and administrative (7,100) 556,600 Total $ 4,900 $ 824,300 On August 20, 2020, the board of directors canceled and terminated RSUs, granted during the quarter ended June 30, 2020.
