Earnings Per Share [Abstract] |
Net Loss per Share Attributable to Common Stockholders | 5. Net Loss per Share Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Because the Company has reported a net loss for all periods presented, diluted net loss per common share is the same as basic net loss per common share for those periods. The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company:
| Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
| 2023 |  |  | 2022 |  |  | 2023 |  |  | 2022 |

The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in common stock equivalent shares):
|  | September 30, |
|  | 2023 |  |  | 2022 |
Options to purchase common stock |  |  | 10,530,750 |  |  |  | 7,386,063 |
