Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Principles of Consolidation: The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Arrys Therapeutics, Inc. (“Arrys”), Ikena Oncology Securities Corporation, and Amplify Medicines, Inc, (“Amplify”). All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates: The preparation of the Company’s financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and judgments are based on historical information and other market-specific or various relevant assumptions, including in certain circumstances, future projections, that management believes to be reasonable under the circumstances. Actual results could differ materially from estimates. Significant estimates and assumptions are used for, but not limited to the accruals for research and development expenses and research and development revenue under a collaboration agreement. Summary of Significant Accounting Policies: The significant accounting policies and estimates used in the preparation of the accompanying consolidated financial statements are described in the Company’s audited consolidated financial statements for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K that was filed with the SEC on March 14, 2023. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2023 except as discussed below. Concentration of Credit Risk and of Significant Suppliers: Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, and marketable securities. Cash and cash equivalents are deposited with federally insured financial institutions in the United States and may, at times, exceed federally insured limits. The Company places marketable securities with a highly rated financial institution. Additionally, as of June 30, 2023, the Company has not experienced any credit related losses on accounts that hold the Company’s cash, cash equivalents and marketable securities. The Company is dependent on third-party manufacturers and clinical research organizations (“CROs”) to supply products and provide services for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply it with its requirements for the active pharmaceutical ingredients and formulated drugs related to these programs. The Company also relies on at least two CROs to conduct its clinical trials. The Company’s programs could be adversely affected if a third-party manufacturer or a CRO is unable to successfully carry out their contractual obligations or meet expected deadlines. If a third-party manufacturer or a CRO needs to be replaced, the Company may not be able to complete its program development on its anticipated timelines and may incur additional expenses as a result, which could be significant. Recent Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial statements and disclosures.
