Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business | 1. Description of Business The Company’s mission is to identify, develop, and commercialize innovative therapies that change patients’ lives for the better. The Company focuses on small-molecule therapeutics with novel mechanisms of action for the treatment of severe, life-threatening diseases with few or no approved therapies. The Company’s lead programs are in rare forms of chronic kidney disease (CKD) and rare forms of neurological diseases. The Company’s lead product candidates, bardoxolone methyl (bardoxolone) in CKD and omaveloxolone in neurological diseases, activate the transcription factor Nrf2 to normalize mitochondrial function, restore redox balance, and resolve inflammation. Because mitochondrial dysfunction, oxidative stress, and inflammation are features of many diseases, the Company believes bardoxolone and omaveloxolone have many potential clinical applications. The Company has reported top-line efficacy and safety Year 1 results from its registrational CARDINAL Phase 3 clinical trial of bardoxolone in CKD caused by Alport syndrome. Alport syndrome is a rare and serious hereditary disease with no approved therapy. The trial met its primary and key secondary Year 1 endpoints. CARDINAL demonstrated a statistically significant change in the estimated glomerular filtration rate (eGFR) relative to placebo after 48 weeks of treatment and in retained eGFR, which is the change in eGFR after 48 weeks of treatment and a four-week withdrawal period. Subject to discussions with regulatory authorities, the Company plans to proceed with the submission of regulatory filings for marketing approval in the United States and internationally. The Company has reported top-line efficacy and safety results from its registrational part 2 portion of the MOXIe Phase 2 trial of omaveloxolone in Friedreich’s ataxia (FA). FA is a rare, inherited, debilitating, and degenerative neuromuscular disorder with no approved therapy. The trial demonstrated statistically significant evidence of efficacy for its primary endpoint of change in the modified Friedreich’s Ataxia Rating Scale (mFARS) relative to placebo after 48 weeks of treatment. Subject to discussions with regulatory authorities, the Company plans to proceed with the submission of regulatory filings for marketing approval in the United States and internationally. The Company is also conducting two additional registrational trials: FALCON, studying bardoxolone in patients with autosomal dominant polycystic kidney disease (ADPKD), and CATALYST, studying bardoxolone in patients with a rare and serious form of pulmonary arterial hypertension (PAH) caused by connective tissue disease (CTD-PAH). The Company initiated enrollment of FALCON in May 2019, and the Company expects to have top-line data from CATALYST in mid-2020. The Company’s consolidated financial statements include the accounts of all majority-owned subsidiaries. Accordingly, the Company’s share of net earnings and losses from these subsidiaries is included in the consolidated statements of operations. Intercompany profits, transactions, and balances have been eliminated in consolidation. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The consolidated balance sheet at December 31, 2018, has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, refer to the annual consolidated financial statements and footnotes thereto of the Company. The Company’s significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in its Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Annual Report on Form 10-K). During the first quarter of 201 9 , the Company adopted Accounting Standards Update (ASU) No. 201 6-02 , Leases (Topic 842). As a result of the adoption of Topic 842, the Company has updated its Lease s accounting policies. There were no other changes to its significant accounting policies from those disclosed in its 201 8 Annual Report on Form 10-K. Liquidity As of September 30, 2019, the Company had cash and cash equivalents of $240,149,000. The Company has experienced losses and negative operating cash flows for many years since inception and has no marketed drug or other products. The Company’s ability to generate future revenue depends upon the results of its development programs, the success of which cannot be guaranteed. The Company expects its current cash and its access to additional equity or debt funding will enable it to meet its current obligations through December 31, 2020. See Note 9, Subsequent Events Leases At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on the unique facts and circumstances present in that arrangement. Lease assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are initially recognized at the lease commencement date based on the present value of lease payments over the lease term calculated using its incremental borrowing rate based on the information available at commencement unless the implicit rate is readily determinable. Lease assets also include upfront lease payments, lease incentives paid, and direct costs incurred and exclude lease incentives received. The lease term used to calculate the lease assets and related lease liabilities includes the options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. Lease expense for operating leases is recognized on a straight-line basis over the expected lease term as an operating expense while the expense for finance leases is recognized as depreciation expense over the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. The Company will account for each lease component separately from the nonlease components. The depreciable life of lease assets and leasehold improvements is limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of its exercise. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expenses for these short-term leases and operating leases are recognized on a straight-line basis over the lease term. Recently Adopted Accounting Pronouncements The Company is an emerging growth company (EGC), as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected not to avail itself of this exemption from new or revised accounting standards, and, therefore, will be subject to the same new or revised accounting standards as public companies that are not emerging growth companies. The Company will remain an EGC until December 31, 2019. In February 2016, the Financial Accounting Standards Board (FASB) issued Topic 842, amended by ASU 2018-11, Leases (Topic 842): Targeted Improvements As a result of implementing Topic 842, the Company recognized an operating lease right-of-use asset of $1,544,000 and an operating lease liability of $1,659,000 on January 1, 2019, with no impact on its beginning retained earnings, consolidated statements of operations, or cash flows. See Note 5, Leases In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements (ASU 2018-09). This ASU provided various minor codification updates and improvements to address comments that the FASB had received regarding unclear or vague accounting guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year. The adoption of this guidance did not have a material impact on our financial position, results of operations or disclosures. In July 2019, the FASB issued ASU No. 2019-07, Codification Updates to SEC Sections . The ASU clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC’s regulations, thereby eliminating redundancies and making the codification easier to apply. The guidance is effective upon issuance. the Company’s reported consolidated financial results.

Income Taxes | 6. Income Taxes The Company’s effective tax rate varies with the statutory rate due primarily to the impact of nondeductible stock-based compensation and the changes in valuation allowance related to certain deferred tax assets generated or utilized in the applicable period. The Company’s deferred tax assets have been fully offset by a valuation allowance at September 30, 2019, and the Company expects to maintain this valuation allowance until there is sufficient evidence that future earnings can be achieved, which is uncertain at this time. The IRS examination team has completed its examination of the Company’s 2013, 2014, and 2015 U.S. tax returns and proposed adjustments with respect to certain items that were reported by the Company for the 2013 tax year. In June 2018, the Company received the Revenue Agent Report from the IRS. The Company believes that it has accurately reported all amounts in its tax returns and has submitted an administrative protest with the IRS contesting the examination team’s proposed adjustments. The Company intends to vigorously defend its reported positions and believes the ultimate resolution of the adjustments proposed by the IRS examination team will not have a material adverse effect on its consolidated financial statements. |

Basis of Presentation | Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The consolidated balance sheet at December 31, 2018, has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

Liquidity | Liquidity As of September 30, 2019, the Company had cash and cash equivalents of $240,149,000. The Company has experienced losses and negative operating cash flows for many years since inception and has no marketed drug or other products. The Company’s ability to generate future revenue depends upon the results of its development programs, the success of which cannot be guaranteed. The Company expects its current cash and its access to additional equity or debt funding will enable it to meet its current obligations through December 31, 2020. See Note 9, Subsequent Events |
Leases | Leases At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on the unique facts and circumstances present in that arrangement. Lease assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are initially recognized at the lease commencement date based on the present value of lease payments over the lease term calculated using its incremental borrowing rate based on the information available at commencement unless the implicit rate is readily determinable. Lease assets also include upfront lease payments, lease incentives paid, and direct costs incurred and exclude lease incentives received. The lease term used to calculate the lease assets and related lease liabilities includes the options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. Lease expense for operating leases is recognized on a straight-line basis over the expected lease term as an operating expense while the expense for finance leases is recognized as depreciation expense over the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. The Company will account for each lease component separately from the nonlease components. The depreciable life of lease assets and leasehold improvements is limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of its exercise. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expenses for these short-term leases and operating leases are recognized on a straight-line basis over the lease term. |
Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements The Company is an emerging growth company (EGC), as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected not to avail itself of this exemption from new or revised accounting standards, and, therefore, will be subject to the same new or revised accounting standards as public companies that are not emerging growth companies. The Company will remain an EGC until December 31, 2019. In February 2016, the Financial Accounting Standards Board (FASB) issued Topic 842, amended by ASU 2018-11, Leases (Topic 842): Targeted Improvements As a result of implementing Topic 842, the Company recognized an operating lease right-of-use asset of $1,544,000 and an operating lease liability of $1,659,000 on January 1, 2019, with no impact on its beginning retained earnings, consolidated statements of operations, or cash flows.

The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year. The adoption of this guidance did not have a material impact on our financial position, results of operations or disclosures. In July 2019, the FASB issued ASU No. 2019-07, Codification Updates to SEC Sections .
