11. Net Loss per Share

Basic and diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common stock and pre-funded warrants outstanding during the period without consideration of common stock equivalents. For periods in which the Company generated a net loss, the Company does not include the potential impact of dilutive securities in diluted net loss per share, as the impact of these items is anti-dilutive.

The following equity instruments were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented:


	Six months ended June 30,
	2022		2021
Awards under equity incentive plan		6,064,278		5,125,189
Non-vested restricted shares and restricted stock units		1,141,875		357,022
Warrants to purchase common stock		77,793		3,552,695
Total		7,283,946		9,034,906
