Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Description of Business | Organization and Description of Business Centessa Pharmaceuticals plc (“Centessa” or “the Company”) is a clinical-stage pharmaceutical company that aims to discover, develop and ultimately deliver medicines that are transformational for patients. Centessa was incorporated on October 26, 2020 as a limited liability company under the laws of England and Wales. In connection with the Company’s initial public offering, or IPO, the Company re-registered Centessa Pharmaceuticals Limited as an English public limited company and renamed it as Centessa Pharmaceuticals plc. Risks and Liquidity The Company is subject to risks common to other life science companies in various stages of development including, but not limited to, uncertainty of product development and commercialization, lack of marketing and sales history, development by its competitors of new technological innovations, dependence on key personnel, market acceptance of products, product liability, protection of proprietary technology, ability to raise additional financing and compliance with government regulations in the markets in which the Company is seeking approvals, including U.S. Food and Drug Administration (“FDA”) regulations. If the Company does not successfully advance its prog rams, into an d through human clinical trials and/or enter into collaborations for its programs and commercialize any of its product candidates, it may be unable to produce product revenue or achieve profitability. The Company has incurred losses and negative cash flows from operations since inception and the Company had an accumulated deficit of $791.0 million as of March 31, 2024. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of the product candidates currently in development. Substantial additional capital will be needed by the Company to fund its operations and to develop its product candidates. The Company expects its existing cash, cash equivalents and short-term investments as of March 31, 2024 of $230.2 million will be sufficient to fund its expected operating expenses and capital expenditure requirements for at least the next twelve months from the date of issuance of these unaudited interim consolidated financial statements. Shelf Registration Statement On July 12, 2022, the Securities and Exchange Commission (“SEC”) declared effective the Company’s filed shelf registration statement on Form S-3 (“Shelf”), which covers the offering, issuance and sale of an amount up to $350.0 million in the aggregate of the Company’s ordinary shares, American Depository Shares representing ordinary shares, debt securities, warrants, and/or units or any combination thereof. The Company entered into a Sales Agreement, dated January 27, 2023, by and between Centessa Pharmaceuticals plc and Leerink Partners LLC (formerly SVB Securities LLC). As sales agent, Leerink Partners LLC will provide for the issuance and sale by the Company of up to $125.0 million of its ordinary shares represented by American Depository Shares (“ADSs”) from time to time in “at-the-market” offerings under the Shelf (“ATM Program”). In January 2024, the Company sold 1,250,000 ordinary shares under the ATM Program, resulting in net proceeds of $9.7 million. As of March 31, 2024, the Company has sold 4,290,816 ordinary shares under the ATM Program, resulting in net proceeds to us of approximately $30.5 million. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The accompanying unaudited interim consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements of Centessa Pharmaceuticals plc and related notes which can be found in our Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”). The Summary of Significant Accounting Policies included in the Company’s annual financial statements have not materially changed, except as set forth below. Basis of Presentation and Consolidation The accompanying unaudited interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASUs”) promulgated by the Financial Accounting Standards Board (“FASB”). In the opinion of management, the accompanying unaudited interim consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the financial statements) considered necessary to present fairly: • the Company’s financial position as of March 31, 2024 and as of December 31, 2023; • the Company’s results of operations for the three months ended March 31, 2024 and March 31, 2023; and • the Company’s cash flows for the three months ended March 31, 2024 and March 31, 2023. Operating results for the Company for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the full year. The unaudited interim consolidated financial statements presented herein do not contain all of the required disclosures under U.S. GAAP for annual financial statements. Notes to the financial statements which would substantially duplicate the disclosure contained in the audited financial statements for fiscal 2023 as reported in the 2023 Annual Report have been omitted. Therefore, these unaudited interim consolidated financial statements should be read in conjunction with the annual audited consolidated financial state ments and related notes for Centessa Pharmaceuticals plc found in the Form 10-K for the year ended December 31, 2023 filed with the SEC. The Company’s unaudited interim consolidated financial statements include the accounts of Centessa Pharmaceuticals plc, and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Emerging Growth Company and Smaller Reporting Company We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act (“JOBS Act”) enacted in April 2012. For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier to occur of (1) the last day of the fiscal year that is five years following the closing of our initial public offering, (2) the last day of the fiscal year in which we have total annual gross revenues of at least $1.235 billion, (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer,” under the rules of the SEC, which means the market value of our equity securities that is held by non-affiliates exceeds $700 million as of the prior June 30th after we have been subject to the SEC’s periodic reporting requirements for at least twelve calendar months and have filed at least one annual report, and (4) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We are electing to utilize the extended transition period and, as a result, will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for emerging growth companies. We are also a “smaller reporting company” as defined in the Securities Exchange Act of 1934 (“Exchange Act”). Even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company” if the market value of our ordinary shares held by non-affiliates is below $250 million (or $700 million if our annual revenue is less than $100 million) as of June 30 in any given year. As a smaller reporting company, we are eligible for scaled disclosure relief from certain Regulation S-X and Regulation S-K requirements. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts, certificate of deposits, money market funds and U.S. Treasury securities. Short Term Investments The Company invests its excess cash in cash deposits, U.S. Treasury securities and SEC-registered money market funds. Securities with original maturities of three months or less when purchased are included in Cash and cash equivalents. The Company considers investments with original maturities greater than three months and remaining maturities less than one year to be short-term investments. As of March 31, 2024, all investments in U.S. Treasury securities were classified as available-for-sale securities, which are recorded at fair value. Unrealized holding gains and losses on available-for-sale securities are reported net of related income taxes in accumulated other comprehensive income until realized. Purchase premiums and discounts are amortized to interest income over the terms of the related securities. Concentrations of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and short-term investments. The Company’s cash, cash equivalents and short-term investments are held by financial institutions primarily in the United States and the United Kingdom. Amounts on deposit may at times exceed federally insured limits. Management believes that the financial institutions are financially sound, and accordingly, the Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. These reclassifications had no effect on previously reported net loss or comprehensive loss. Use of Estimates The preparation of unaudited interim consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited interim consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined to be necessary. On an ongoing basis, an evaluation of estimates and judgments are required, including those related to accrued research and development expenses, the Note Purchase Agreement, share-based compensation and tax related matters. Estimates are based on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Property and Equipment, net and Capitalized Software under Cloud Computing Arrangements Property and equipment are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the respective assets. Property and equipment includes computer equipment, furniture and office equipment. The costs of maintenance and repairs are expensed as incurred. Improvements and betterment that add new functionality or extend the useful life of the asset are capitalized. Depreciation expense for the three-month periods ended March 31, 2024 and March 31, 2023 were $86 thousand and $37 thousand , respectively. Costs related to the implementation of cloud computing arrangements that are service contracts incurred during the application development stage are capitalized and included in the same line item as a prepayment for corresponding hosting service fees. Capitalized costs are amortized over the shorter of its estimated useful life and the term of the hosting arrangement, including anticipated extensions. Costs incurred during the preliminary project stage and the post-implementation-operation stage are expensed as incurred. Hosting fees associated with hosting as a service arrangement are expensed on a straight-line basis over the term of the hosting arrangement. Amortization expense for the three months periods ended March 31, 2024 and March 31, 2023 were $154 thousand and $52 thousand , respectively. Leases In accordance with ASU No. 2016-02, Leases (“ASC 842”) , the Company assesses whether an arrangement is a lease, or contains a lease at the inception of the arrangement. When an arrangement contains a lease, the Company categorizes leases with contractual terms longer than twelve months as either operating or finance. Finance leases are generally those leases that allow us to substantially utilize or pay for the entire asset over its estimated life. Assets acquired under finance leases are recorded in “Property and equipment, net.” All other leases are categorized as operating leases. The Company records right-of use ("ROU") assets and lease obligations for its finance and operating leases, which are initially recognized based on the discounted future lease payments over the term of the lease. As the rate implicit in the Company's leases may not be easily determinable, the Company uses its incremental borrowing rate to calculate the present value of the sum of the lease payments. Lease terms may include options to extend or terminate the lease. The Company will include such options in determining the lease term when it is reasonably certain that the Company will exercise such options. Operating and finance lease ROU assets are recognized net of any lease prepayments and incentives. The Company elected the practical expedient to not separate lease and non-lease components and, accordingly, accounts for them as a single lease component. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense is recognized based on the effective-interest method over the lease term. The Company elected not to recognize ROU assets and lease obligations for any short-term leases, which are defined as leases with an initial term of 12 months or less. Long-Lived Assets Long-lived assets, comprised of property and equipment and operating lease right-of-use assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, then an impairment charge is recognized for the amount by which the carrying value of the asset exceeds the estimated fair value of the asset. No impairments of long-lived assets for the three-month periods ended March 31, 2024 and 2023 were recognized by the Company. Note Purchase Agreement In October 2021, the Company entered into a Note Purchase Agreement (the “NPA”) with Oberland Capital. As described in further detail in Note 5 - "Debt" , as of March 31, 2024, in addition to a secured note in the principal amount of $75 million, which was funded on October 4, 2021, Oberland Capital has agreed to purchase tranches of secured notes in the aggregate principal amount of up to $175 million, including up to $75 million through September 2024, at the Company’s option ; and up to $100 million at any time at the Company’s and Purchasers’ option, to be used to finance certain permitted acquisitions as described in the NPA. In addition, the Company is obligated to pay a Milestone payment equal to 30% of the aggregate principal amount issued under the Notes by the Company upon regulatory approval of any drug candidate. The Company evaluated the Notes and determined that the Notes include embedded derivatives that would otherwise require bifurcation as derivative liabilities. Neither the debt instrument nor any embedded features are required to be classified as equity. Therefore, the hybrid financial instrument comprised of the debt host and the embedded derivative liability may be accounted for under the fair value option. The Company elected to carry the Notes at fair value, and the debt instrument is outside the scope of ASC 480, Distinguishing Liabilities from Equity , and thus will be classified as a liability under ASC 470, Debt , in the Company’s financial statements. As the Company has elected to account for the Notes under the fair value option, debt issuance costs were immediately expensed. The fair value of the Note Purchase Agreement represents the present value of estimated future payments, including interest, principal as well as estimated payments that are contingent upon the achievement of specified milestones. The fair value of the Notes is based on the cumulative probability of the various estimated payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving the milestones, anticipated timelines, probability and timing of an early redemption of all obligations under the Note Purchase Agreement and the discount rate. Any changes in the fair value of the liability in each reporting period are recognized in the consolidated statement of operations and comprehensive loss until it is settled. Net Loss Per Ordinary Share Basic loss per ordinary share is computed by dividing net loss by the aggregate weighted-average number of ordinary shares outstanding. Diluted loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred shares, stock options, unvested restricted ordinary shares and convertible debt which would result in the issuance of incremental ordinary shares. For diluted net loss per ordinary share, the weighted-average number of ordinary shares is the same for basic net loss per ordinary share due to the fact that when a net loss exists, dilutive securities are not included in the calculation as the impact is anti-dilutive. The following potentially dilutive securities have been excluded from the computation of diluted weighted-average ordinary shares outstanding for the three months ended March 31, 2024 and March 31, 2023, as they would be anti-dilutive: Three Months Ended Three Months Ended Unvested ordinary shares 253,518 481,623 Restricted stock units 2,447,121 2,730,370 Stock options 18,716,239 15,978,480 21,416,878 19,190,473 |

Fair Value Disclosures [Abstract] | |
Fair Value Measurement | Fair Value Measurement Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company’s financial instruments, including cash, prepaid expense and accounts payable, are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic 820, Fair Value Measurement , for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liabilities. Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following fair value hierarchy table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis (amounts in thousands): Fair value measurement at reporting date using Quoted prices Significant Significant March 31, 2024 Assets Money Market fund $ 26,700 $ — $ — U.S. Treasury securities $ 111,959 $ — $ — Liabilities Note Purchase Agreement $ — $ — $ 76,800 December 31, 2023 Assets Money Market fund $ 28,339 $ — $ — U.S. Treasury securities $ 128,519 $ — $ — Liabilities Note Purchase Agreement $ — $ — $ 75,700 We classify our investments in available-for-sale U.S. Treasury securities and the money market fund into Level 1 of the ASC Topic 820 hierarchy because fair values represent quoted market prices for identical or comparable instruments. The following represents the amortized cost bases and fair values of the Company’s U.S. Treasury securities and its money market fund as of March 31, 2024 (amounts in thousands): Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Money Market fund, included in Cash and cash equivalents $ 26,700 $ — $ — $ 26,700 U.S. Treasury securities, included in: Short-term investments 110,073 1,886 — 111,959 Total U.S. Treasury securities $ 110,073 $ 1,886 $ — $ 111,959 For the Company's financial instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the following table provides a reconciliation of the beginning and ending balances for each category therein (amounts in thousands): Note Purchase Agreement Balance at January 1, 2023 $ 69,800 Change in fair value 5,900 Balance at December 31, 2023 $ 75,700 Change in fair value 1,100 Balance at March 31, 2024 $ 76,800 The fair value of the Note Purchase Agreement represents the present value of estimated future payments, including interest, principal as well as estimated payments that are contingent upon the achievement of specified milestones. The fair value of the notes is based on the cumulative probability of the various estimated payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving the milestones, anticipated timelines, probability and timing of an early redemption of all obligations under the agreement and discount rate. Any changes in the fair value of the liability are recognized in the consolidated statement of operations and comprehensive loss until it is settled. For the three months ended March 31, 2024, the Company recorded an unrealized loss of $1.1 million for the estimated change in fair value of the Note Purchase Agreement, which was recorded in Other (Expense) Income, net in the consolidated statement of operations and comprehensive loss. The unrealized loss primarily reflects the accretion of discount. |

Debt | Debt Debt as of March 31, 2024 and December 31, 2023 (in thousands): March 31, December 31, Note Purchase Agreement $ 76,800 $ 75,700 On October 1, 2021 (the “Signing Date”), the Company, as issuer, and certain of the Company’s wholly owned subsidiaries, as guarantors (the “Guarantors”), entered into a Note Purchase Agreement (the “NPA”) with Oberland Capital Management LLC (the “Purchasers”) and Cocoon SA LLC (the “Agent”), an affiliate of Oberland Capital Management LLC, as agent for the Purchasers. On February 11, 2022, on November 7, 2022 and on June 23, 2023, the Company, the Guarantors, the Purchasers and the Agent agreed to certain amendments to the Note Purchase Agreement, memorialized in the “Amendment”, the “Second Amendment”, and the “Third Amendment” respectively. The Note Purchase Agreement, collectively with the amendments, is hereinafter referred to as the NPA. As of March 31, 2024, in addition to a secured note in the principal amount of $75 million , which was funded on October 4, 2021 (the “First Purchase Date”), the Purchasers have agreed to purchase tranches of secured notes in the aggregate principal amount of up to $175 million, including up to $75 million through September 2024, at the Company’s option ; and up to $100 million at any time at the Company’s and Purchasers’ option, to be used to finance certain permitted acquisitions as described in the NPA. The notes under the NPA will mature on the six-year anniversary of the First Purchase Date, unless earlier accelerated under the terms of the NPA. At maturity, the Company must repay the outstanding principal amount of the Notes, together with any accrued and unpaid interest thereon and other outstanding obligations thereunder. Interest is payable quarterly during the term of the Notes at a rate per annum equal to the sum of (a) the greater of (i) the Secured Overnight Financing Rate (“SOFR”) (which may be subject to replacement as contemplated by the NPA) and (ii) 0.25%; plus (b) 7.75% (which percentage is subject to adjustment as described in the NPA); provided that the interest rate shall never be less than 8.00%. The average interest rate over the three months ended March 31, 2024 was 13.3% per annum compared with an average interest rate of 12.50% per annum over the three months ended March 31, 2023. The Company’s obligations under the facility are secured by a first priority security interest in all assets of the Company and Guarantors, subject to variation in accordance with local law with respect to assets held by the Company and the Guarantors outside of the United States. Upon the first regulatory approval of any of the Company’s product candidates by either the FDA or the European Medicines Agency (“EMA”), the Company is obligated to pay the Purchasers an amount equal to 30% of the aggregate principal amount issued under the Notes by the Company (the “Milestone Payment”). The Milestone Payment shall be paid in quarterly installments over 5 years beginning on the earlier of (i) the date of the first commercial sale following such regulatory approval; and (ii) the six month anniversary of such regulatory approval. The Milestone Payment is triggered one time only, and applies only to the Company’s first product to obtain regulatory approval. The Company may redeem all, but not less than all, of the outstanding notes (if any) and pay all other outstanding obligations under the NPA. On the applicable date, the Company shall repurchase the notes by paying an amount of up to (i) 175% of the principal amount issued under the notes if such repurchase occurs on or prior to the third anniversary of the First Purchase Date, (ii) 185% of the principal amount issued under the notes if such repurchase occurs between the third and sixth anniversaries of the First Purchase Date, and (iii) 205% of the principal amount issued under the notes if such repurchase occurs thereafter, in each case less specified deductions and exclusions described in the NPA, including amounts paid by the Company to the Purchasers in respect of certain asset sale or strategic transactions, the interest payments and the Milestone Payments (the “Final Payment Amount”). As of March 31, 2024 , the Company has made cumulative payments under the NPA, including interest payments, totaling $21.2 million . Conversely, the Purchasers may require the Company to redeem any outstanding notes by payment of the Final Payment Amount upon a sale, divestment or transfer of all or substantially all assets of the Company in a transaction or series of transactions or a change of control of the Company, a material breach of the NPA and related transaction documents, an event of default under the NPA or the tenth anniversary of the First Purchase Date (or such earlier date as described in the NPA). In addition, upon certain asset sales and similar strategic transactions by the Company with respect to its own or its subsidiaries’ assets or businesses as described in the NPA (other than a change of control described above), the Purchasers may require the Company to pay an amount in cash equal to up to 75% of the Net Proceeds (as defined in the NPA) received from such asset sales, subject to a $100 million deductible such that the Purchaser Agent will not collect any repurchase amounts until $100 million has been received by the Company from such sale event (the “Deductible”). The NPA contains customary affirmative and negative covenants, including with respect to notice obligations, limitations on new indebtedness, liens, investments and transactions with affiliates of the Company, restrictions on the payment of dividends, maintenance of collateral accounts in the amount of 90% of the aggregate outstanding principal amount of all issued notes, maintenance of insurance and addition of new subsidiaries as obligors. It also contains customary representations and warranties in favor of the Purchasers and the Agent and customary events of default, which may cause the obligations of the Company to be accelerated. Such events include among others, failure to make payments when due, breach of covenants, insolvency, a cross-default to other indebtedness, a judgment event of default, and delisting of the Company’s securities from the Nasdaq Global Select Market. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Commitments As of March 31, 2024, the Company had non-cancellable commitments for purchase of clinical materials, contract manufacturing, maintenance, and committed funding of up to $68.7 million, of which the Company expects to pay $51.6 million within one year and $17.1 million over one to five years. The amount and timing of these payments vary depending on the rate of progress of development. Future clinical trial expenses have not been included within the purchase commitments because they are contingent on enrollment in clinical trials and the activities required to be performed by the clinical sites. Leases On February 7, 2022, the Company entered into an operating lease for its new corporate headquarters in Boston, Massachusetts (the “Boston Lease”). After a build out of the space, the Boston Lease commenced on March 31, 2023. The 10-year Boston Lease is for 18,922 square feet with a fixed annual rent of approximately $1.6 million commencing in 2023 and escalating to approximately $1.9 million by year 10 . The Boston Lease required the Company to issue a letter of credit in the amount of $0.7 million in favor of the landlord. The Company may, at its discretion, extend the Boston Lease for one extension term of five years. As of March 31, 2024, the Company has recognized an operating lease right-of-use asset, net of $11.7 million, including capitalized leasehold improvements that will be owned by the landlord, prepayments of rent, and a corresponding lease liability of $9.3 million . On October 11, 2023, the Company entered into a five-year agreement to sublet 4,242 square feet of the Boston Lease, which may be extended at subtenant’s option. The following table provides balance sheet information related to leases as of March 31, 2024 (amounts in thousands): March 31, 2024 Assets: Operating lease, right-of-use asset $ 11,694 Liabilities: Current portion of operating lease liabilities $ 528 Operating lease liabilities, net of current portion 8,744 Total operating lease liabilities $ 9,272 In calculating the present value of the lease payments, the Company elected to utilize its incremental borrowing rate based on the original term of the lease.

As of March 31, 2024 , the Company had no licensing and collaborative arrangement milestone obligations recorded on its balance sheet. License Agreement with Heptares Limited in connection with Orexin Program The Company is party to a license, assignment, and research services agreement with Heptares Therapeutics Limited (“Heptares”), relating to certain specific molecules with, among other criteria, the primary mode of action of an orexin agonist or orexin positive modulator (“Molecules”). Under the agreement, Heptares assigned to the Company all of Heptares’ right, title, and interest in and to intellectual property that is already in existence and that is developed as a result of the agreement that relates solely to Molecules or products that contain Molecules (“Products”), including all rights to obtain patent or similar protection throughout the world for such intellectual property and to take any and all actions regarding past infringements of existing intellectual property. Additionally, Heptares granted to the Company an exclusive, sublicensable (subject to certain terms) license to make, import, export, use, sell, or offer for sale, including to development, commercialization, registration, modification, enhancement, improvement, manufacturing, holding, keeping or disposing of Molecules and Products. Heptares must not by itself or through a third party (other than a single company) exploit, use or dispose of ( inter alia ) any product in the field of orexin agonism and orexin positive modulation for the duration of the agreement and for three years thereafter. In consideration for the assignment and license, the Company is to pay Heptares a royalty in the low single-digits on net sales of Products (subject to limitations in certain scenarios). Royalties are on a Product-by-Product and country-by country basis. Payments shall commence with the first commercial sale of such product in a country and shall continue until the later of: (a) the duration of regulatory exclusivity in the country; or (b) ten years after the first commercial sale. Further, the Company is responsible for all development costs incurred by itself or Heptares in the performance of the research program (within the confines of the research budget). Additionally, the Company must pay Heptares, on a Molecule-by-Molecule basis, development milestone payments in the aggregate of a low double-digit number in the millions of pounds sterling. Milestone payments are payable once per Molecule. The Company anticipates paying between the low single digits millions of pounds sterling to low double digit millions of pounds sterling in the next twelve months. The Company may terminate the agreement at any time following the expiration or termination of the research program. In addition, customary termination rights exist for both parties for breach and insolvency. In the event of termination, all licenses automatically terminate. The term of the agreement is until the later of: (i) the expiration of the last to expire patent within the licensed intellectual property; (ii) the expiration of the royalty term; and (iii) the fifteenth anniversary of the effective date. Upon expiration, with respect to any given Molecule, the license granted to the Company shall become perpetual, irrevocable, and fully-paid up. Other License and Collaboration Agreements The Company is a party to other license and collaboration agreements to develop and commercialize intellectual property in addition to the agreement discussed above. In aggregate, Centessa is obligated to make up to $4.8 million and $15.0 million in development and commercial milestone payments, respectively, related to these other agreements. Contingencies From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. Litigation On September 28, 2022 (“Original Complaint”), the Company and certain of its current and former officers were named as defendants in a proposed class-action lawsuit filed in the United States District Court for the Central District of California. The complaint generally alleges that the Company violated Sections 10(b) and 20(a) and Sections 11 and 15 of the Securities Act of 1933, as amended (the “Securities Act”) by allegedly making materially false and/or misleading statements, as well as allegedly failing to disclose material adverse facts relating to the safety profile and future clinical and commercial prospects of each of its lixivaptan and ZF874 programs, which caused the Company’s securities to trade at artificially inflated prices. On October 12, 2022, by order, the lawsuit was transferred to the United States District Court for the Southern District of New York. On February 10, 2023, an amended complaint was filed (“Amended Complaint”) in which our IPO underwriters were added as co-defendants. A number of the claims set forth in the Original Complaint have been abandoned including with respect to intentional fraud theory and claims pursuant to Sections 10(b) or 20(a) of the Securities Exchange Act of 1934. The only claims alleged in the Amended Complaint are violations of Sections 11 and 15 of the Securities Act based on alleged misstatements in the S-1 filed by the Company in connection with its Initial Public Offering. The Amended Complaint also abandoned any claims concerning ZF874 and focuses entirely on lixivaptan. The Amended Complaint seeks damages and attorneys’ fees, among other things. On August 23, 2023, the Company submitted its motion to dismiss all claims, which remains pending. The Company believes this lawsuit is without merit and intends to defend the case vigorously. Litigation is subject to inherent uncertainty and a court could ultimately rule against the Company. In addition, the defense of litigation and related matters are costly and may divert the attention of the Company’s management and other resources that would otherwise be engaged in other activities. The Company has not recorded an estimate of the possible loss associated with this legal proceeding due to the uncertainties related to both the likelihood and the amount of any possible loss or range of loss. |

Share-Based Payment Arrangement [Abstract] | |
Share-based Compensation | Share-based Compensation Centessa Pharmaceuticals plc Stock Option and Incentive Plan In January 2021, the Company’s board of directors approved the 2021 Stock Option and Incentive Plan (the “2021 Plan”). The 2021 Plan provides for the granting of ordinary shares, incentive stock options, non-qualified stock options, restricted share awards, restricted stock units and/or share appreciation rights to employees, directors, and other persons, as determined by the Company’s board of directors. The number of shares authorized under the 2021 Plan was increased in May 2021 at the time of the IPO, whereby the total number of shares authorized under the 2021 Plan was 20,026,816. Beginning on January 1, 2022 and each January 1 thereafter, the number of shares reserved and available for issuance under the 2021 Plan shall be cumulatively increased by 5% of the number of shares issued and outstanding on the immediately preceding December 31, or such lesser number as the board of directors may determine. Remaining shares available for future grants as of March 31, 2024 were 9,445,643. Share-based Compensation Expense The Company recorded share-based compensation expense in the following expense categories in the unaudited interim consolidated statements of operations and comprehensive loss (amounts in thousands): Three Months Ended Three Months Ended Research and development $ 3,725 $ 3,284 General and administrative 4,429 3,906 $ 8,154 $ 7,190 Stock Options The following table summarizes stock option activity for the three months ended March 31, 2024: Number of Shares Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term Balance at January 1, 2024 16,069,015 $ 7.09 7.9 years Granted 2,874,100 $ 8.10 Exercised (176,460) $ 5.41 Forfeited (50,416) $ 8.18 Balance at March 31, 2024 18,716,239 $ 7.25 8.0 years Exercisable at March 31, 2024 9,250,365 $ 7.41 7.3 years Vested and expected to vest at March 31, 2024 18,716,239 $ 7.25 8.0 years The weighted-average grant date fair value of options granted was $5.57 per share for the three months ended March 31, 2024. As of March 31, 2024, the total unrecognized compensation expense related to unvested stock option awards was $41.1 million, which the Company expects to recognize over a weighted-average period of 2.6 years. Based on the trading price of $11.30 per ADS, which is the closing price as of March 31, 2024, the aggregate intrinsic value of options as of March 31, 2024 was $81.2 million. During the three months ended March 31, 2024, the fair value of each option was estimated on the date of grant using the weighted average assumptions in the table below: Expected term 5.9 years Expected stock price volatility 76.3 % Risk-free interest rate 3.8 % Expected dividend yield 0 % The Company uses the Black-Scholes option pricing model to value its stock option awards. The expected life of the stock options is estimated using the “simplified method,” as the Company has limited historical information from which to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for its stock option grants. The simplified method is the midpoint between the vesting period and the contractual term of the option. For share price volatility, the Company uses comparable public companies as a basis for its expected volatility to calculate the fair value of option grants. The risk-free rate is based on the U.S. Treasury yield curve commensurate with the expected life of the option. Forfeitures of stock options are recognized in the period the forfeiture occurs. Restricted Share Awards and Units In connection with the acquisition of the Centessa subsidiaries in January 2021, the Company issued 379,905 ordinary shares subject to future vesting under its Restricted Stock Awards program. For the period subsequent to the acquisition, the Company issued an additional 833,897 ordinary shares subject to future vesting to an employee. The fair value of the awards were based upon the estimated fair value of the Company’s ordinary shares at the time of grant. The Board, following the recommendations of the Company’s Compensation Committee, grants service-based restricted stock unit awards under the Company’s Stock Incentive Plan to certain executive officers and employees of the Company to encourage employee retention. Periodic grants are made at fair market value, representing the NASDAQ market close quoted price on the day of the grant. The following table summarizes ordinary share activity related to the restricted stock programs for the three months ended March 31, 2024: Restricted Stock Awards Restricted Stock Units Number of Shares Weighted-Average Grant Date Fair Value Per Share Number of Shares Weighted-Average Grant Date Fair Value Per Share Unvested at January 1, 2024 310,052 1,949,463 Granted — n/a 938,850 $ 8.01 Vested (56,534) (424,392) Forfeited — (16,800) Unvested at March 31, 2024 253,518 2,447,121 Unrecognized compensation expense at March 31, 2024 (in thousands) $ 4,632 $ 13,575 Expected weighted average recognition period 1.1 years 2.9 years Employee Share Purchase Plan In January 2021, the Company’s board of directors approved the 2021 Employee Share Purchase Plan (the “ESPP”). The initial number of shares reserved for issuance under the 2021 ESPP was 860,000. On January 1, 2022 and each January 1 thereafter, the number of shares reserved and available for issuance under the ESPP shall be cumulatively increased by a number of shares equal to the lesser of: (i) 1% of the number of Shares issued and outstanding on the immediately preceding |

Accounting Policies [Abstract] | |
Basis of Presentation and Consolidation | Basis of Presentation and Consolidation The accompanying unaudited interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASUs”) promulgated by the Financial Accounting Standards Board (“FASB”). In the opinion of management, the accompanying unaudited interim consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the financial statements) considered necessary to present fairly: • the Company’s financial position as of March 31, 2024 and as of December 31, 2023; • the Company’s results of operations for the three months ended March 31, 2024 and March 31, 2023; and • the Company’s cash flows for the three months ended March 31, 2024 and March 31, 2023. Operating results for the Company for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the full year. The unaudited interim consolidated financial statements presented herein do not contain all of the required disclosures under U.S. GAAP for annual financial statements. Notes to the financial statements which would substantially duplicate the disclosure contained in the audited financial statements for fiscal 2023 as reported in the 2023 Annual Report have been omitted. Therefore, these unaudited interim consolidated financial statements should be read in conjunction with the annual audited consolidated financial state ments and related notes for Centessa Pharmaceuticals plc found in the Form 10-K for the year ended December 31, 2023 filed with the SEC. The Company’s unaudited interim consolidated financial statements include the accounts of Centessa Pharmaceuticals plc, and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts, certificate of deposits, money market funds and U.S. Treasury securities. |
Short Term Investments | Short Term Investments The Company invests its excess cash in cash deposits, U.S. Treasury securities and SEC-registered money market funds. Securities with original maturities of three months or less when purchased are included in Cash and cash equivalents. The Company considers investments with original maturities greater than three months and remaining maturities less than one year to be short-term investments. |
Concentrations of Credit Risk | Concentrations of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and short-term investments. The Company’s cash, cash equivalents and short-term investments are held by financial institutions primarily in the United States and the United Kingdom. Amounts on deposit may at times exceed federally insured limits. Management believes that the financial institutions are financially sound, and accordingly, the Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. |
Reclassifications | Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. These reclassifications had no effect on previously reported net loss or comprehensive loss. |
Use of Estimates | Use of Estimates The preparation of unaudited interim consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited interim consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined to be necessary. On an ongoing basis, an evaluation of estimates and judgments are required, including those related to accrued research and development expenses, the Note Purchase Agreement, share-based compensation and tax related matters. Estimates are based on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. |

Capitalized costs are amortized over the shorter of its estimated useful life and the term of the hosting arrangement, including anticipated extensions. Costs incurred during the preliminary project stage and the post-implementation-operation stage are expensed as incurred. Hosting fees associated with hosting as a service arrangement are expensed on a straight-line basis over the term of the hosting arrangement. |
Leases | Leases In accordance with ASU No. 2016-02, Leases (“ASC 842”) , the Company assesses whether an arrangement is a lease, or contains a lease at the inception of the arrangement. When an arrangement contains a lease, the Company categorizes leases with contractual terms longer than twelve months as either operating or finance. Finance leases are generally those leases that allow us to substantially utilize or pay for the entire asset over its estimated life. Assets acquired under finance leases are recorded in “Property and equipment, net.” All other leases are categorized as operating leases. The Company records right-of use ("ROU") assets and lease obligations for its finance and operating leases, which are initially recognized based on the discounted future lease payments over the term of the lease. As the rate implicit in the Company's leases may not be easily determinable, the Company uses its incremental borrowing rate to calculate the present value of the sum of the lease payments. Lease terms may include options to extend or terminate the lease. The Company will include such options in determining the lease term when it is reasonably certain that the Company will exercise such options. Operating and finance lease ROU assets are recognized net of any lease prepayments and incentives. The Company elected the practical expedient to not separate lease and non-lease components and, accordingly, accounts for them as a single lease component. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense is recognized based on the effective-interest method over the lease term. The Company elected not to recognize ROU assets and lease obligations for any short-term leases, which are defined as leases with an initial term of 12 months or less. |
Long-Lived Assets | Long-Lived Assets Long-lived assets, comprised of property and equipment and operating lease right-of-use assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, then an impairment charge is recognized for the amount by which the carrying value of the asset exceeds the estimated fair value of the asset. No impairments of long-lived assets for the three-month periods ended March 31, 2024 and 2023 were recognized by the Company. |
Note Purchase Agreement | Note Purchase Agreement In October 2021, the Company entered into a Note Purchase Agreement (the “NPA”) with Oberland Capital. As described in further detail in Note 5 - "Debt" , as of March 31, 2024, in addition to a secured note in the principal amount of $75 million, which was funded on October 4, 2021, Oberland Capital has agreed to purchase tranches of secured notes in the aggregate principal amount of up to $175 million, including up to $75 million through September 2024, at the Company’s option ; and up to $100 million at any time at the Company’s and Purchasers’ option, to be used to finance certain permitted acquisitions as described in the NPA. In addition, the Company is obligated to pay a Milestone payment equal to 30% of the aggregate principal amount issued under the Notes by the Company upon regulatory approval of any drug candidate. The Company evaluated the Notes and determined that the Notes include embedded derivatives that would otherwise require bifurcation as derivative liabilities. Neither the debt instrument nor any embedded features are required to be classified as equity. Therefore, the hybrid financial instrument comprised of the debt host and the embedded derivative liability may be accounted for under the fair value option. The Company elected to carry the Notes at fair value, and the debt instrument is outside the scope of ASC 480, Distinguishing Liabilities from Equity , and thus will be classified as a liability under ASC 470, Debt , in the Company’s financial statements. As the Company has elected to account for the Notes under the fair value option, debt issuance costs were immediately expensed. The fair value of the Note Purchase Agreement represents the present value of estimated future payments, including interest, principal as well as estimated payments that are contingent upon the achievement of specified milestones. The fair value of the Notes is based on the cumulative probability of the various estimated payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving the milestones, anticipated timelines, probability and timing of an early redemption of all obligations under the Note Purchase Agreement and the discount rate. Any changes in the fair value of the liability in each reporting period are recognized in the consolidated statement of operations and comprehensive loss until it is settled. |
Net Loss Per Ordinary Share | Net Loss Per Ordinary Share Basic loss per ordinary share is computed by dividing net loss by the aggregate weighted-average number of ordinary shares outstanding. Diluted loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred shares, stock options, unvested restricted ordinary shares and convertible debt which would result in the issuance of incremental ordinary shares. For diluted net loss per ordinary share, the weighted-average number of ordinary shares is the same for basic net loss per ordinary share due to the fact that when a net loss exists, dilutive securities are not included in the calculation as the impact is anti-dilutive. |
