(Loss) Per Share [Abstract] |
(Loss) Per Share | 9. Loss Per Share Basic and diluted net loss per share attributable to common stockholders was calculated for the periods indicated (in thousands, except share and per share data):
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  |  | Year Ended December 31,
​ | ​ | ​ | 2022 | ​ | 2021
Numerator: | ​ | ​ | ​ |  |  | ​ |
Net loss | ​ | ​ | $ | (41,428) | ​ | $ | (43,078)
Denominator: | ​ | ​ |  |  | ​ |  |
Weighted average common shares outstanding — basic and diluted | ​ | ​ |  | 20,532,838 | ​ |  | 10,360,054
Net loss per share attributable to common stockholders — basic and diluted | ​ | ​ | $ | (2.02) | ​ | $ | (4.16)
​ The Company’s potentially dilutive securities, which include stock options, shares of convertible preferred stock, warrants to purchase shares of convertible preferred stock and warrants to purchase shares of common stock, have been excluded from the computation of diluted net loss per share attributable to common stockholders, as the effect would be to reduce the net loss per share attributable to common stockholders. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect: ​

​ |  | Year Ended December 31,

Options to purchase common stock |  | 3,756,835 |  | 2,749,441
Warrants to purchase common stock | ​ | 716,131 | ​ | 716,131
​ |  | 4,472,966 |  | 3,465,572
