Other Non-Current Liabilities Other Non-Current Liabilities
Included within other non-current liabilities at December 31, 2021 and 2020 is $2,531 and $2,263, respectively, relating to assumed contingent liabilities. As part of the acquisition of Discuva Limited in December 2017, the Company assumed certain contingent liabilities as certain employees, former employees and former directors of Discuva Limited are eligible for payments from Discuva Limited based on specified development and clinical milestones related to proprietary product candidates developed under the Discuva Platform. The timing of these potential payments is uncertain.

The contingent liability was remeasured in the third quarter of 2020 to reflect a change in the timing of expected payments following the Company's decision not to advance the DDS-01 series of antibiotics and to cease work on the gonorrhoeae program. The gain on the remeasurement of the liability recognized during the year ended December 31, 2020 of $480 is included within other (expense) income in the consolidated statements of operations and comprehensive loss. There were no remeasurement losses or gains recognized during the year ended December 31, 2021.
