6. Net Loss Per Share of Common Stock

Diluted net loss per share is the same as basic net loss per share for all periods presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss. Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding.

 

The following table sets forth the computation of basic and diluted net loss per share for common stockholders:

 

		Three Months Ended March 31,
		2018				2017
Net loss		$	(19,106,481	)		$	(6,348,164	)
Weighted average shares of common stock outstanding			73,656,534				41,656,006
Net loss per share of common stock—basic and diluted		$	(0.26	)		$	(0.15	)

The following potentially dilutive securities outstanding at March 31, 2018 and 2017 have been excluded from the computation of diluted weighted average shares outstanding, as they would have been anti-dilutive given the Company’s net loss:

 

		March 31,
		2018				2017
Options to purchase common stock			7,475,106				5,907,782
Warrants to purchase common stock			36,267,603				20,334,442
Total			43,742,709				26,242,224
