Organization, Business and Basis of Presentation | Organization, Business, and Basis of Presentation Organization and Business Madrigal Pharmaceuticals, Inc. (the “Company” or “Madrigal”) is a biopharmaceutical company dedicated to transforming care for patients with nonalcoholic steatohepatitis (“NASH”), a serious liver disease that can lead to cirrhosis, liver failure and premature mortality. The Company's medication, Rezdiffra (resmetirom), is a once-daily, oral, liver-directed THR-β agonist designed to target key underlying causes of NASH. In March 2024, Rezdiffra became the first and only FDA-approved therapy for patients with NASH. Rezdiffra is indicated in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principle of Consolidation The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, and the reported amounts of revenues and expenses during the reporting periods. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits. The primary objective of the Company’s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company’s cash is deposited in highly rated financial institutions in the United States. The Company invests in money market funds and high-grade, commercial paper and corporate bonds, which management believes are subject to minimal credit and market risk. Marketable Securities Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets. The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion as a component of interest income, net. Realized gains and losses and declines in value, if any, that the Company judges to be the result of impairment or as a result of recognizing an allowance for credit losses on available-for-sale securities are reported as a component of interest income. To determine whether an impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three months ended March 31, 2024 and 2023, the Company determined it did not have any securities that were other-than-temporarily impaired. Marketable securities are stated at fair value, including accrued interest, with their unrealized gains and losses included as a component of accumulated other comprehensive income or loss, which is a separate component of stockholders’ equity. The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method. During the three months ended March 31, 2024 and 2023, the Company did not have any realized gains or losses on marketable securities. Fair Value of Financial Instruments The carrying amounts of the Company’s financial instruments, which include cash equivalents and marketable securities, approximate their fair values. The fair value of the Company’s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels: Level 1—quoted prices in active markets for identical assets and liabilities. Level 2—observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3—unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Financial assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third- party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. As of March 31, 2024, the Company’s financial assets valued based on Level 1 inputs consisted of cash and cash equivalents in a money market fund, its financial assets valued based on Level 2 inputs consisted of high-grade corporate and government agency bonds and commercial paper, and it had no financial assets valued based on Level 3 inputs. During the three months ended March 31, 2024 and 2023, the Company did not have any transfers of financial assets between Levels 1 and 2. As of March 31, 2024 and December 31, 2023, the Company did not have any financial liabilities that were recorded at fair value on a recurring basis on the balance sheet. Inventory Inventory is stated at the lower of cost or estimated net realizable value, using actual cost, based on a first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels quarterly and writes down inventory subject to expiry or in excess of expected requirements, or that has a cost basis in excess of its expected net realizable value. These write downs are charged to cost of goods sold in the accompanying Consolidated Statements of Income. The Company considered regulatory approval of its product candidate to be uncertain and product manufactured prior to regulatory approval could not have been sold unless regulatory approval was obtained. As such, the manufacturing costs incurred prior to regulatory approval were not capitalized as inventory, but were expensed as incurred as research and development expenses. Research and Development Costs Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation), costs for consultants, milestone payments under licensing agreements, and other costs associated with the Company’s preclinical and clinical programs. In particular, the Company has conducted safety studies in animals, optimized and implemented the manufacturing of its drug, and conducted clinical trials, all of which are considered research and development expenditures. Management uses significant judgment in estimating the amount of research and development costs recognized in each reporting period. Management analyzes and estimates the progress of its clinical trials, completion of milestone events per underlying agreements, invoices received and contracted costs when estimating the research and development costs to accrue in each reporting period. Actual results could differ from the Company’s estimates. Patents Costs to secure and defend patents are expensed as incurred and are classified as selling, general and administrative expense in the Company’s consolidated statements of operations. Intangible Assets Intangible assets with finite lives are amortized to cost of goods sold over their estimated useful lives using the straight-line method. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Stock-Based Compensation The Company recognizes stock-based compensation expense based on the grant date fair value of stock options, restricted stock units, and other stock-based compensation awards granted to employees, officers, directors, and consultants. Awards that vest as the recipient provides service are expensed on a straight-line basis over the requisite service period. The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company’s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary. For other stock-based compensation awards granted to employees and directors that vest based on market conditions, such as the trading price of the Company’s common stock achieving or exceeding certain price targets, the Company uses a Monte Carlo simulation model to estimate the grant date fair value and recognize stock compensation expense over the derived service period. The Monte Carlo simulation model requires key inputs for risk-free interest rate, dividend yield, volatility, and expected life. The assumptions used in computing the fair value of equity awards reflect the Company’s best estimates but involve uncertainties related to market and other conditions. Changes in any of these assumptions may materially affect the fair value of awards granted and the amount of stock-based compensation recognized. Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets. Income Taxes The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company’s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. The Company currently maintains a 100% valuation allowance on its deferred tax assets. Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company’s net loss and comprehensive loss. Basic and Diluted Loss Per Common Share Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the three months ended March 31, 2024 and 2023, diluted net loss per share is the same as basic net loss per share because the inclusion of weighted average shares of common stock issuable upon the exercise of stock options and warrants or vesting of restricted stock units, and common stock issuable upon the conversion of preferred stock would be anti-dilutive. The following table summarizes outstanding securities not included in the computation of diluted net loss per common share, as their inclusion would be anti-dilutive: Outstanding at March 31, 2024 2023 Common stock options 2,458,227 2,676,598 Restricted stock units 530,671 199,125 Performance-based restricted stock units 252,404 — Preferred stock 2,369,797 2,369,797 Warrants 3,625,244 17,352 Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for operating segments in the Company's annual and interim consolidated financial statements.

Liquidity and Uncertainties | Liquidity and Uncertainties The Company is subject to risks common to development stage companies and early commercial companies in the biopharmaceutical industry including, but not limited to, uncertainty of product development and commercialization, dependence on key personnel, uncertainty of market acceptance of products and product reimbursement, product liability, uncertain protection of proprietary technology, potential inability to raise additional financing necessary for development and commercialization, and compliance with the U.S. Food and Drug Administration (“FDA”) and other government regulations. The Company has incurred losses since inception, including approximately $147.5 million for the three months ended March 31, 2024, resulting in an accumulated deficit of approximately $1,483.8 million as of March 31, 2024. To date, the Company has funded its operations primarily through proceeds from sales of the Company’s capital stock and debt financings. In March 2024, the FDA approved Rezdiffra in the U.S. for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Rezdiffra became available in the U.S. in April 2024. In March 2024, the Company completed a public offering and received approximately $574.0 million net cash proceeds. In April 2024, underwriters exercised in full their option to purchase additional shares as part of the public offering, resulting in additional net cash proceeds of approximately $85.9 million.

Debt Disclosure [Abstract] | |
Long Term Debt | Long Term Debt In May 2022 the Company and its wholly-owned subsidiary, Canticle Pharmaceuticals, Inc., entered into the $250.0 million Loan Facility with the several banks and other financial institutions or entities party thereto (each, a “Lender” and collectively referred to as the “Lenders”), and Hercules Capital, Inc. (“Hercules”), in its capacity as administrative agent and collateral agent for itself and the Lenders. Under the terms of the Loan Facility, the first $50.0 million tranche was drawn at closing. The Company also could draw up to an additional $125.0 million in two separate tranches upon achievement of certain resmetirom clinical and regulatory milestones. A fourth tranche of $75.0 million could have been drawn by the Company, subject to the approval of Hercules. The Loan Facility had a minimum interest rate of 7.45% and adjusted with changes in the prime rate. The Company was originally scheduled to pay interest-only monthly payments of accrued interest under the Loan Facility through May 1, 2025, for a period of 36 months. In March 2024, the interest-only period was extended to May 1, 2026 when the Company achieved a milestone when Rezdiffra received FDA approval. The interest only period can further be extended to May 3, 2027, upon the achievement of future revenue milestones, subject to compliance with applicable covenants. The Loan Facility originally matured in May 2026, but the maturity date was extended to May 2027 when the Company achieved a milestone upon receipt of FDA approval in March 2024. The Loan Facility is secured by a security interest in substantially all of the Company’s assets, other than intellectual property. It includes an end of term charge of 5.35% of the aggregate principal amount, which is accounted for in the loan discount. In connection with the first tranche drawn at closing, the Company issued Hercules a warrant to purchase 14,899 shares of Company common stock, which had a Black-Scholes value of $0.6 million. On February 3, 2023, the Company entered into the First Amendment (the “Amendment”) to the Loan Facility (as amended, the “Amended Loan Facility”). Under the Amended Loan Facility, an additional $35.0 million was drawn under a second, expanded, $65.0 million tranche (“Tranche 2”) in February of 2023 following the Company’s achievement of the Phase 3 clinical development milestone. An additional $15.0 million was drawn under Tranche 2 in June of 2023. The remaining $15.0 million available under Tranche 2 was drawn in September of 2023 in accordance with the Amended Loan Facility. The third tranche (“Tranche 3”) of $75.0 million remains unchanged by the Amendment, and such borrowings became available when the Company achieved a milestone with FDA approval for Rezdiffra in March 2024. As of March 31, 2024, the Company has not drawn down on Tranche 3, and the $75.0 million remains available until June 12, 2024. Coincident with the expansion of Tranche 2 borrowing capacity by $15.0 million, the Amendment reduced the fourth tranche under the Loan Facility (“Tranche 4”) by $15.0 million to $60.0 million, which is available subject to Hercules’ sole discretion. In connection with the $35.0 million drawn under Tranche 2 at the closing of the Amendment, $15.0 million drawn in June of 2023, and $15.0 million drawn in September of 2023, the Company issued to Hercules and affiliates Tranche 2 Warrants to purchase an aggregate of 4,555 shares of common stock, which had a Black-Scholes value of $0.9 million. The Amendment reduced the interest rate under the Amended Loan Facility to the greater of (i) the prime rate as reported in The Wall Street Journal plus 2.45% and (ii) 8.25%. The Amendment and the Amended Loan Facility summary terms were disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on February 9, 2023. The Loan Facility includes affirmative and restrictive financial covenants commencing on January 1, 2023, including maintenance of a minimum cash, cash equivalents and liquid funds covenant of $35.0 million, which may decrease in certain circumstances if the Company achieves certain clinical milestones and a revenue milestone, and a revenue-based covenant that could apply commencing at or after the time that financial reporting is due for the quarter ending September 30, 2024. The Loan Facility contains event of default provisions for: the Company’s failure to make required payments or maintain compliance with covenants under the Loan Facility; the Company’s breach of certain representations or default under certain obligations outside the Loan Facility; insolvency, attachment or judgment events affecting the Company; and any circumstance which has occurred or could reasonably be expected to have a material adverse effect on the Company, provided that, any failure to achieve a clinical milestone or approval milestone under the Loan Facility shall not in and of itself constitute a material adverse effect. The Loan Facility also includes customary covenants associated with a secured loan facility, including covenants concerning financial reporting obligations, and certain limitations on indebtedness, liens (including a negative pledge on intellectual property and other assets), investments, distributions (including dividends), collateral, investments, distributions, transfers, mergers or acquisitions, taxes, corporate changes, and deposit accounts. As of March 31, 2024, the outstanding principal under the Loan Facility was $115.0 million. The interest rate as of March 31, 2024 was 10.95%. As of March 31, 2024, the Company was in compliance with all loan covenants and provisions. Future minimum payments, including interest and principal, under the loans payable outstanding as of March 31, 2024 are as follows (in thousands): Period Ending March 31, 2024: Amount 2024 $ 9,619 2025 12,768 2026 79,604 Thereafter 53,387 $ 155,378 Less amount representing interest (34,225) Less unamortized discount (5,018) Loans payable, net of discount $ 116,135 |

Principle of Consolidation | Principle of Consolidation |
Use of Estimates | Use of Estimates |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits. |
Marketable Securities | Marketable Securities Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying amounts of the Company’s financial instruments, which include cash equivalents and marketable securities, approximate their fair values. The fair value of the Company’s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels: Level 1—quoted prices in active markets for identical assets and liabilities. Level 2—observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3—unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability. |
Inventory | Inventory Inventory is stated at the lower of cost or estimated net realizable value, using actual cost, based on a first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels quarterly and writes down inventory subject to expiry or in excess of expected requirements, or that has a cost basis in excess of its expected net realizable value. These write downs are charged to cost of goods sold in the accompanying Consolidated Statements of Income. |
Research and Development Costs | Research and Development Costs Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation), |
Patents | Patents |
Intangible Assets | Intangible Assets Intangible assets with finite lives are amortized to cost of goods sold over their estimated useful lives using the straight-line method. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. |
Stock-Based Compensation | Stock-Based Compensation The Company recognizes stock-based compensation expense based on the grant date fair value of stock options, restricted stock units, and other stock-based compensation awards granted to employees, officers, directors, and consultants. Awards that vest as the recipient provides service are expensed on a straight-line basis over the requisite service period. The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company’s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary. For other stock-based compensation awards granted to employees and directors that vest based on market conditions, such as the trading price of the Company’s common stock achieving or exceeding certain price targets, the Company uses a Monte Carlo simulation model to estimate the grant date fair value and recognize stock compensation expense over the derived service period. The Monte Carlo simulation model requires key inputs for risk-free interest rate, dividend yield, volatility, and expected life. The assumptions used in computing the fair value of equity awards reflect the Company’s best estimates but involve uncertainties related to market and other conditions. Changes in any of these assumptions may materially affect the fair value of awards granted and the amount of stock-based compensation recognized. Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets. |
Income Taxes | Income Taxes The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company’s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the |
