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 September 30,								Nine Months Ended September 30,
		2018				2017				2018				2017
Net loss		$	(4,377,747	)		$	(1,575,098	)		$	(43,620,120	)		$	(10,760,150	)
Weighted average shares of common stock outstanding			77,447,599				64,960,354				74,934,774				49,509,486
Net loss per share of common stock—basic and diluted		$	(0.06	)		$	(0.02	)		$	(0.58	)		$	(0.22	)

 

The following potentially dilutive securities outstanding at September 30, 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:

 

		September 30,
		2018				2017
Options to purchase common stock			7,248,198				6,016,984
Warrants to purchase common stock			31,265,182				36,270,103
Total			38,513,380				42,287,087
