Stock-Based Compensation Expense

 

Stock-based compensation expense related to stock options is recognized on a straight-line basis over the requisite service period for the award and is allocated to research and development expense or general and administrative expense based upon the classification of the individuals to whom the awards are granted. Stock-based compensation expense related to stock option grants was $103,569 and $228,039 during the three-month periods ended March 31, 2024 and 2023, respectively, and as of March 31, 2024, there is $451,023 of unrecognized compensation expense that we expect to recognize over a weighted-average period of 1.3 years.

 

We have also issued shares of our restricted common stock to consultants and recognize the related expense over the terms of the related agreements. During the three-month periods ended March 31, 2024 and 2023 we recorded stock-based compensation expense of $54,167 and $18,000, respectively, associated with common stock issued for consulting services.
