The following table sets forth the computation of basic and diluted net loss per share (in thousands, except for share and per share amounts):

	2019			2018
Numerator:
Net loss	$	(51,373	)	$	(48,435	)
Denominator:
Weighted-average common shares outstanding - basic and diluted		30,284,068			23,882,685
Net loss per share - basic and diluted	$	(1.70	)	$	(2.03	)

The Company’s potentially dilutive shares, which include outstanding stock options and unvested restricted common stock, are considered to be common share equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following potential common shares, presented based on amounts outstanding at each period end, were excluded from the calculation of the diluted net loss per share attributable to common stockholders for the period indicated because including them would have had an anti-dilutive effect.

	As of December 31,
	2019		2018
Unvested restricted common stock awards		586,929		118,679
Outstanding options to purchase common stock		2,286,419		1,739,884
