(1)During the year ended December 31, 2020, management identified an impairment related to the option over non-financial asset pursuant to an Evaluation and Option Agreement with a collaboration partner. The partner is no longer conducting antibiotic candidate programs over which the Company had the option, management therefore determined that the fair value of the option to acquire the assignment of the proprietary rights for antibiotic candidates is $0. Accordingly, the asset was written off in its entirety resulting in an impairment charge of $859 recognized in operating expenses.

						Amount
2022						$	999
2023						$	999
2024						$	999
