Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements of the Company and its wholly-owned subsidiaries are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and are presented in U.S. dollars. All significant intercompany accounts and transactions between the Company and its subsidiaries have been eliminated on consolidation. The unaudited condensed consolidated financial statements presented in this Quarterly Report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 9, 2022 (the “Annual Report”). The condensed consolidated statement of financial position as of December 31, 2021 was derived from the audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. The Company’s critical accounting policies are detailed in the Annual Report. The Company’s critical accounting policies have not changed materially since December 31, 2021. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from these interim financial statements. However, these condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary to fairly state the results of the interim period. These interim financial results are not necessarily indicative of results to be expected for the full fiscal year ending December 31, 2022, or any other future period.
Use of estimates	Use of estimates The preparation of the Company’s condensed consolidated financial statements requires the use of estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of income and expenses during the period. The Company bases its estimates and assumptions on historical experience and other factors that it believes to be reasonable under the circumstances. The Company evaluates its estimates and assumptions on an ongoing basis. The actual results may differ from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (1) evaluation of costs and measure of progress of the development activities conducted as part of the collaboration agreement with Nestlé Health Science, (2) research tax credits, (3) assumptions used in the valuation of right of use assets - operating lease, (4) impairment of right-of-use assets related to leases and property, plant and equipment, (5) recoverability of the Company's net deferred tax assets and related valuation allowance, (6) assumptions used in the valuation model to determine the fair value and vesting conditions of share-based compensation plan, and (7) estimate of contingencies.
Accounting Pronouncements adopted in 2022	Accounting Pronouncements adopted in 2022 The Company has not adopted any new accounting pronouncements in 2022 to date.
Accounting Pronouncements issued not yet adopted	Accounting Pronouncements issued not yet adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 - Financial Instruments - Credit losses, which replaces the incurred loss impairment methodology for financial instruments in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The FASB has issued ASU 2019-10 which has resulted in the postponement of the effective date of the new guidance for eligible smaller reporting companies to the fiscal year beginning January 1, 2023. The guidance must be adopted using a modified-retrospective approach and a prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The Company is currently evaluating the impact of the guidance on its Consolidated Financial Statements. The Company does not expect this new standard will have a material impact on its consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s Consolidated Financial Statements upon adoption.
