Earnings Per Share [Abstract]  
Net Loss Per Share Net Loss Per Share
Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares.

As a result of the Company’s net loss incurred for the three months ended March 31, 2022 and 2021, all potentially dilutive instruments outstanding would have anti-dilutive effects on per-share calculations for the periods.  Therefore, basic and diluted net loss per share were the same for all periods presented as reflected below.

As of March 31, 2022 and 2021, respectively, the Company’s potentially dilutive instruments included 5,259,847 and 3,905,192 options to purchase common shares and 166,700 and 13,491 unvested restricted stock units that were excluded from the computation of diluted weighted average shares outstanding because these securities had an antidilutive impact due to the losses reported. Similarly excluded as of March 31, 2022 and 2021, were potentially dilutive warrants for the purchase of 1,714,429 for both periods.
