Earnings Per Share [Abstract] |
Net Loss Per Share | Note 2—Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common share equivalents outstanding for the period, determined using the treasury-stock method. Common share equivalents are excluded from the diluted net loss per share computation if their effect is anti-dilutive. The basic and diluted net loss per share amounts for the three and nine months ended September 30, 2019 and 2018 were computed based on the shares of common stock outstanding during the respective periods. Potentially dilutive securities excluded from the diluted loss per share calculation are as follows: ​
​ | ​ | ​ | ​ | ​
​ | ​ | September 30,
​ |  | 2019 |  | 2018
Outstanding options to purchase common stock | ​ | 11,494,722 |  | 10,123,530
Outstanding warrants to purchase common stock | ​ | 243,115 |  | 243,115
Total potentially dilutive shares excluded from loss per share | ​ | 11,737,837 |  | 10,366,645
