Earnings Per Share [Abstract]

Basic and Diluted Net Loss Per Common Share

The following table sets forth the computation of the basic and diluted net loss per common share during the three months ended March 31, 2019 and 2018 (in thousands, except share and per share data):

		Three Months Ended March 31,
		2019				2018
Net loss attributable to common stockholders		$	(15,083	)		$	(5,042	)
Weighted-average number of shares used in computing net loss per    share, basic and diluted			11,963,586				8,989,669
Net loss available for common stockholders per share, basic and    diluted		$	(1.26	)		$	(0.56	)

Anti-dilutive Security not Included In Diluted per Share Calculations

Since the Company was in a loss position for all periods presented, diluted net loss per share is the same as basic net loss per share for all periods as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities on an as-if converted basis that were not included in the diluted per share calculations because they would be anti-dilutive were as follows:

		Three Months Ended March 31,
		2019				2018
Options to purchase common stock			1,612,871				1,026,393
Common stock warrants			10,194				12,039
Redeemable convertible notes			—				—
Total			1,623,065				1,038,432

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
