Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business	Note Nature of Operations Organovo Holdings, Inc. (“Organovo Holdings,” “Organovo,” and the “Company”) is an early-stage biotechnology company that focuses on building high fidelity, 3D tissues that recapitulate key aspects of human disease. The Company uses these models to identify gene targets responsible for driving the disease and intends to initiate drug discovery programs around these validated targets. The Company is initially focusing on the intestine and has ongoing 3D tissue development efforts in ulcerative colitis (“UC”) and Crohn’s disease (“CD”). Recently, the Company announced that it has successfully advanced its first inflammatory bowel disease (“IBD”) model to the next step of target discovery and validation for CD. The Company intends to add additional tissues/diseases/targets to its portfolio over time. In line with these plans, the Company is building upon both its external and in house scientific expertise, which will be essential to its drug development effort. The Company uses its proprietary technology to build functional 3D human tissues that mimic key aspects of native human tissue composition, architecture, function and disease. Organovo’s advances include cell type-specific compartments, prevalent intercellular tight junctions, and the formation of microvascular structures. Management believes these attributes can enable critical complex, multicellular disease models that can be used to develop clinically effective drugs across multiple therapeutic areas. The Company’s NovoGen Bioprinters ® The Company believes that the use of its bioprinting platform as well as complementary 3D technologies will allow it to develop an understanding of disease biology that leads to validated novel drug targets and therapeutics to those targets to treat disease. The majority of the Company’s current focus is in IBD, including CD and UC. The Company is creating high fidelity disease models, leveraging its prior work including the work found in its peer-reviewed publication on bioprinted intestinal tissues ( Madden et al. Bioprinted 3D Primary Human Intestinal Tissues Model Aspects of Native Physiology and ADME/Tox Functions. iScience. 2018 Apr 27;2:156-167. doi: 10.1016/j.isci.2018.03.015.) The Company’s current understanding of intestinal tissue models and IBD disease models leads it to believe that it can create models that provide greater insight into the biology of these diseases than are generally currently available. Using these disease models, the Company has identified and validated novel therapeutic targets and is actively focused on developing novel small molecule, antibody, or other therapeutic drug candidates to treat the disease, and advance these novel drug candidates towards an Investigational New Drug (“IND”) filing and potential future clinical trials. The Company expects to broaden its work into additional therapeutic areas over time and is currently exploring specific tissues for development. In the Company’s work to identify the areas of interest, it evaluates areas that might be better served with 3D disease models than currently available models as well as the potential commercial opportunity. Except where specifically noted or the context otherwise requires, references to “Organovo Holdings”, “the Company”, and “Organovo” in these notes to the consolidated financial statements refers to Organovo Holdings, Inc. and its wholly owned subsidiaries, Organovo, Inc., and Opal Merger Sub, Inc. COVID-19 Global health concerns relating to the COVID-19 pandemic continue to weigh on the macroeconomic environment, and the pandemic has significantly increased economic volatility and uncertainty. The extent to which the coronavirus impacts the Company’s operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the rise of vaccine-resistant variants, the duration of the outbreak, and any travel bans and restrictions or other limitations that may be imposed in the future

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2022 is derived from the Company’s audited consolidated balance sheet at that date. The unaudited condensed consolidated financial statements include the accounts of Organovo and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2022, as filed with the Securities and Exchange Commission (“SEC”). Operating results for any interim period are not necessarily indicative of the operating results for any other interim period or the Company’s full fiscal year ending March 31, 2023 (see “ Note 1. Description of Business” Liquidity As of September 30, 2022, the Company had cash and cash equivalents of approximately $13.3 million, short-term investments of $10.0 million, restricted cash of approximately $0.1 million and an accumulated deficit of approximately $314.3 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease agreement for its facilities. The Company also had negative cash flows from operations of approximately $4.6 million during the six months ended September 30, 2022. Through September 30, 2022, the Company has financed its operations primarily through the sale of convertible notes, warrants, the private placement of equity securities, the sale of common stock through public and at-the-market (“ATM”) offerings, and through revenue derived from product and research service-based agreements, collaborative agreements, licenses, and grants. During the three and six months ended September 30, 2022, the Company issued zero shares of its common stock through its ATM facility. The Company believes its cash and cash equivalents on hand will be sufficient to meet its financial obligations for at least the next 12 months of operations. As the Company continues to focus its efforts on drug discovery and development, it will need to raise additional capital to implement this business plan. The Company cannot predict with certainty the exact amount or timing for any future capital raises. If required, the Company may seek to raise additional capital through debt or equity financings, or through some other financing arrangement. However, the Company cannot be sure that additional financing will be available if and when needed, or that, if available, it can obtain financing on terms favorable to its stockholders. Any failure to obtain financing when required will have a material adverse effect on the Company’s business, operating results, financial condition and ability to continue as a going concern. Use of Estimates The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates used in preparing the unaudited condensed consolidated financial statements include those assumed in revenue recognition and the valuation of stock-based compensation expense. On an ongoing basis, management reviews these estimates and assumptions. Though the impact of the COVID-19 pandemic to its business and operating results presents additional uncertainty, the Company continues to use the best information available to inform its significant accounting estimates. Investments Short-term investments consist of investments in debt securities, specifically in U.S. Treasury bills. Any short-term investments that have original maturities of three months or less are classified as cash equivalents on the Condensed Consolidated Balance Sheet. All short-term investments are classified as held-to-maturity, as the Company has both the positive intent and the ability to hold these securities to maturity. Held-to-maturity debt securities are recorded at amortized cost, which approximates fair value. As U.S. Treasury bills are risk-free and will be held until they mature, any declines in fair value are considered temporary. Investments in equity securities consist of investments in the common stock of entities traded in active markets. The Company does not have the ability to exercise significant influence over any entities. Therefore, initial investments are recorded at cost, and are remeasured at fair value as of the balance sheet date. Any gains or losses resulting from the change in fair value is recorded in net income. The investments in equity securities are classified as current assets. Fair value measurement Financial assets and liabilities are measured at fair value, which is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of September 30, 2022, the Company held short-term investments in U.S. Treasury bills. These short-term investments are recorded at amortized cost, which approximates fair value. Please refer to "Note 3. Investments” for further information. As the short-term investments consist of U.S. Treasury bills from active markets, the fair value is measured using level 1 inputs. As of September 30, 2022, the Company held investments in equity securities. As the investments in equity securities consist of common stock from active markets, the fair value is measured using level 1 inputs. The following table presents the activity for investments in equity securities measured at fair value for the six months ended September 30, 2022: Fair Value Measurements Using Quoted Prices in Active Markets (Level 1) Investment in Equity Securities (in thousands) Balance at March 31, 2022 $ — Purchases at cost 1,061 Sales (368 ) Loss on investment in equity securities (75 ) Balance at September 30, 2022 $ 618 Net Loss Per Share Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“ESPP”), the assumed vesting of restricted stock units (“RSUs”), and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for the three and six months ended September 30, 2022 and 2021 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. Common stock equivalents excluded from computing diluted net loss per share due to their anti-dilutive effect were approximately 1.4 million at September 30, 2022 and 0.7 million at September 30, 2021. Revenue recognition The Company generates revenues from the licensing of intellectual property. Licenses The Company has entered into a license agreement with a company that includes the following: (i) non-refundable upfront fees and (ii) royalties based on specified percentages of net product sales, if any. At the initiation of the agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606. The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the Company is a principal vs. agent, whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-refundable upfront fees have been considered fixed, while sales-based royalty payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. Please refer to “Note 5: Collaborative Research, Development, and License Agreements” for further information. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption.

Investments All Other Investments [Abstract]
Investments	Note 3. Investments Short-term investments consist of investments in debt securities, specifically in U.S. Treasury bills. There were no unrealized gains or losses recorded on short-term investments for the three and six months ended September 30, 2022. As of September 30, 2022, the Company held $10.0 million of short-term investments in six month treasury bills. For the three and six months ended September 30, 2022, there was less than $0.1 million of interest income related to the short-term investments. Investments in equity securities consist of investments in the common stock of entities traded in active markets. For the six months ended September 30, 2022, there was $1.1 million of equity securities purchased, and $0.4 million of equity securities sold. As of September 30, 2022, the fair value of investment in equity securities was $0.6 million, resulting in a $0.1 million unrealized loss on investment in equity securities.

Equity [Abstract]
Stockholders' Equity	Note 4. Stockholders’ Equity Stock-based Compensation Expense and Valuation Information Stock-based awards include stock options and RSUs under the Company’s Amended and Restated 2012 Equity Incentive Plan (“2012 Plan”), inducement awards, performance-based RSUs under an Incentive Award Performance-Based Restricted Stock Unit Agreement, the Company’s 2021 Inducement Equity Incentive Plan (“Inducement Plan”), and rights to purchase stock under the ESPP. The Company calculates the grant date fair value of all stock-based awards in determining the stock-based compensation expense. Stock-based compensation expense for all stock-based awards consists of the following (in thousands): Three Months Ended Three Months Ended Six Months Ended Six Months Ended September 30, 2022 September 30, 2021 September 30, 2022 September 30, 2021 Research and development $ 125 $ 80 $ 246 $ 156 General and administrative $ 548 $ 346 $ 1,087 $ 685 Total $ 673 $ 426 $ 1,333 $ 841 The total unrecognized compensation cost related to unvested stock option grants as of September 30, 2022 was approximately $3.4 million and the weighted average period over which these grants are expected to vest is 2.3 years. The total unrecognized compensation cost related to unvested RSUs (not including performance-based RSUs) as of September 30, 2022 was approximately $0.1 million, which will be recognized over a weighted average period of 2.38 years. The Company uses either the Black-Scholes or Monte Carlo option-pricing models to calculate the fair value of stock options, depending on the complexity of the equity grants. Stock-based compensation expense is recognized over the vesting period using the straight-line method. The assumed dividend yield is based on the Company’s expectation of not paying dividends in the foreseeable future. The Company uses the Company-specific historical volatility rate as the indicator of expected volatility. The risk-free interest rate assumption is based on U.S. Treasury rates. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the options. The measurement and classification of share-based payments to non-employees is consistent with the measurement and classification of share-based payments to employees. The fair value of stock options was estimated at the grant date using the following weighted average assumptions: Three Months Ended Three Months Ended Six Months Ended Six Months Ended September 30, 2022 September 30, 2021 September 30, 2022 September 30, 2021 Dividend yield — — — — Volatility 95.93 % 116.83 % 95.41 % 116.83 % Risk-free interest rate 3.30 % 0.73 % 3.18 % 0.73 % Expected life of options 6.00 years 6.00 years 6.00 years 6.00 years Weighted average grant date fair value $ 1.85 $ 6.52 $ 1.99 $ 6.52 The fair value of each RSU and performance-based RSU is recognized as stock-based compensation expense over the vesting term of the award. The fair value is based on the closing stock price on the date of the grant. The Company uses the Black-Scholes valuation model to calculate the fair value of shares issued pursuant to the ESPP. Stock-based compensation expense is recognized over the purchase period using the straight-line method. The fair value of ESPP shares was estimated at the purchase period commencement date using the following assumptions: Three Months Ended Three Months Ended Six Months Ended Six Months Ended September 30, 2022 September 30, 2021* September 30, 2022 September 30, 2021* Dividend yield — — — — Volatility 86.58 % 0.00 % 86.58 % 0.00 % Risk-free interest rate 3.34 % 0.00 % 3.34 % 0.00 % Expected term 6 months — 6 months — Grant date fair value $ 0.82 $ — $ 0.82 $ — *There were no participants in the ESPP for the purchase periods beginning March 1, 2021 or September 1, 2021. The assumed dividend yield is based on the Company’s expectation of not paying dividends in the foreseeable future. The Company uses the Company-specific historical volatility rate as the indicator of expected volatility. The risk-free interest rate assumption is based on U.S. Treasury rates. The expected life is the 6-month purchase period. There was one participant in the ESPP for the current purchase period (beginning September 1, 2022). Preferred Stock The Company is authorized to issue 25,000,000 shares of preferred stock. There are no shares of preferred stock currently outstanding, and the Company has no current plans to issue shares of preferred stock. Common Stock The Company previously had an effective shelf registration statement on Form S-3 (File No. 333-222929) and the related prospectus previously declared effective by the SEC on February 22, 2018 (the “2018 Shelf”), which registered $100.0 million of common stock, preferred stock, warrants and units, or any combination of the foregoing, that was set to expire on February 22, 2021. On January 19, 2021, the Company filed a shelf registration statement on Form S-3 (File No. 333-252224) to register $150.0 million of the Company’s common stock, preferred stock, debt securities, warrants and units, or any combination of the foregoing (the “2021 Shelf”) and a related prospectus. The 2021 Shelf was declared effective by the SEC on January 29, 2021 and replaced the 2018 Shelf at that time. On March 16, 2018, the Company entered into a Sales Agreement (“Sales Agreement”) with H.C. Wainwright & Co., LLC and Jones Trading Institutional Services LLC (each an “Agent” and together, the “Agents”). On January 29, 2021, the Company filed a prospectus supplement to the 2021 Shelf (the “ATM Prospectus Supplement”), pursuant to which the Company may offer and sell, from time to time through the Agents, shares of its common stock in ATM sales transactions having an aggregate offering price of up to $50.0 million. Any shares offered and sold will be issued pursuant to the 2021 Shelf. During the three and six months ended September 30, 2022, the Company issued zero shares of common stock in ATM offerings under the ATM Prospectus Supplement. As of September 30, 2022, the Company has sold an aggregate of 1,580,862 shares of common stock in ATM offerings under the ATM Prospectus Supplement, with gross proceeds of approximately $21.7 million. As of September 30, 2022, there was approximately $100.0 million available for future offerings under the 2021 Shelf (excluding amounts available but not yet issued under the ATM Prospectus Supplement), and approximately $28.3 million available for future offerings through the Company’s ATM program under the ATM Prospectus Supplement. In March 2021, the Company’s Board of Directors (“Board”) approved the Inducement Plan. The Inducement Plan authorized the issuance of up to 750,000 shares of common stock for awards of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, RSUs, performance units, performance shares, and other stock or cash awards. RSUs The following table summarizes the Company’s RSUs (not including performance-based RSUs) activity from March 31, 2022 through September 30, 2022: Number of Shares Weighted Average Price Unvested at March 31, 2022 15,500 $ 10.58 Granted — $ — Vested (2,726 ) $ 11.07 Cancelled / forfeited — $ — Unvested at September 30, 2022 12,774 $ 10.47 Stock Options During the three and six months ended September 30, 2022 under the 2012 Plan, 126,262 and 199,921 stock options were granted at various exercise prices, respectively. On October 7, 2021, the Company granted 30,000 and 7,500 stock options, respectively, to its Executive Chairman and its Chief Scientific Officer under the 2012 Plan. These stock options have unique vesting criteria based on specific Company performance conditions. The vesting criteria relates to the Company closing a seven-figure cash up front deal with a major pharmaceutical company. As of September 30, 2022, management estimated there was a 0% probability of achievement, and therefore no expense has been recorded to date. The following table summarizes the Company’s stock option activity from March 31, 2022 to September 30, 2022: Options Outstanding Weighted Average Exercise Price Aggregate Intrinsic Value Outstanding at March 31, 2022 1,203,671 $ 7.36 $ 71,650 Options granted 199,921 $ 2.56 $ — Options cancelled / forfeited — $ — $ — Options exercised — $ — $ — Outstanding at September 30, 2022 1,403,592 $ 6.68 $ 1,503 Vested and Exercisable at September 30, 2022 339,232 $ 7.57 $ — The weighted average remaining contractual term of stock options exercisable and outstanding at September 30, 2022 was approximately 8.27 years Employee Stock Purchase Plan In June 2016, purchase common stock through payroll deductions, limited to 15 percent of each employee’s compensation up to $ 25,000 per employee per year or shares per employee per six -month purchase period.

Collaborative Research, Development, and License Agreements	Note 5. Collaborative Research, Development, and License Agreements License Agreements From June 2021 to February 2022, certain patents owned or sublicensed by the Company became the subject of IPR proceedings filed by Cellink AB and its subsidiaries, MatTek Incorporated and Visikol, Inc. (collectively, “BICO Group AB”). The Company and BICO Group AB were also engaged in litigation regarding patent infringement during the same time period. On February 22, 2022, the Company and BICO Group AB signed a settlement and patent license agreement (“License Agreement”) to close all matters noted above. In addition to closing all legal matters and patent disputes noted above, as part of the agreement, the Company agreed to grant a non-exclusive license to BICO Group AB to use the Company’s aforementioned patents for its business operations of manufacturing and selling bioprinters as well as bioinks. The Company concluded that the nature of the license granted represents functional intellectual property. As part of the License Agreement, BICO Group AB agreed to pay the Company a one-time, nonrefundable upfront fee of $1,500,000. Based on Topic 606, the Company concluded that the performance obligation related to this upfront fee consisted of the Company filing stipulations of dismissal of all legal matters noted above, as well as the Company granting the non-exclusive license of the aforementioned patents within five days of receiving the upfront payment. The conditions of the performance obligation were satisfied, and therefore the Company recognized revenue of $1,500,000 on February 22, 2022, the executed date of the License Agreement. Additionally, as part of the License Agreement, BICO Group AB agreed to pay the Company ongoing sales-based royalties (based on percentages of BICO Group AB’s net sales) for the use of the granted license. The sales-based royalties became effective beginning on February 22, 2022, the effective date of the License Agreement, and continue until the expiration of the last surviving licensed patent. As the sales-based royalties are required to be paid 45 days after the end of every quarter, there is variable consideration that must be estimated to determine royalty revenue within a given reporting period. For the three and six months ended September 30, 2022, the Company recorded $77,000 There is an additional performance obligation for sales-based royalties occurring from July 1, 2022 to September 30, 2022. As the sales-based royalties are required to be paid 45 days after the end of every quarter, there is variable consideration that must be estimated to determine royalty revenue within a given reporting period. However, after analyzing all available information, the Company concluded that there are constraints on the estimates of variable consideration because there is a lack of complete and accurate information available. BICO Group AB has been unable to timely deliver complete sales reports by product as stipulated in the License Agreement. Therefore, the Company concluded that there is a risk of significant reversal when the uncertainty associated with the variable consideration is resolved. As a result, no revenue is recognized related to this performance obligation for the three months ended September 30, 2022. Also as part of the License Agreement, certain patents involved in the agreement are sublicensed by the Company from the University of Missouri and Clemson University. See below for further information. University of Missouri In March 2009, the Company entered into a license agreement with the Curators of the University of Missouri to in-license certain technology and intellectual property relating to self-assembling cell aggregates and to intermediate cellular units. The Company received the exclusive worldwide rights to commercialize products comprising this technology for all fields of use. The Company is required to pay the University of Missouri royalties ranging from 1% to 3% of net sales of covered tissue products, and of the fair market value of covered tissues transferred internally for use in the Company’s commercial service business, depending on the level of net sales achieved by the Company each year. The Company paid minimum annual royalties of $25,000 in January 2022 and January 2021 for their respective calendar years, which is credited against royalties due during the subsequent twelve months. No payments have been made in excess of the minimum annual royalties in the years ended March 31, 2022 and 2021. The license agreement terminates upon expiration of the patents licensed and is subject to certain conditions as defined in the license agreement, which is expected to expire after 2029. The license agreement with the University of Missouri also includes an additional sales royalty of 3% of all revenue received from a sublicensee, when such sublicense is entered pursuant to settlement of litigation. Such revenue shall include, but not be limited to, all option fees, license issue fees (up-front payments), license maintenance fees, equity, and all royalty payments. Such revenue shall not include research funding provided to licensee by sublicensee. However, per the agreement, in the event that the Company defends the technology by litigation, it can offset any royalties due by legal expenses incurred. As of September 30, 2022, the Company’s legal expenses exceeded royalties owed from the upfront payment and sales-based royalties related to the License Agreement. Therefore, no royalty expense to the University of Missouri was recorded for the six months ended September 30, 2022. No royalty expense related to sales-based royalties has been recorded to date. Clemson University In May 2011, the Company entered into a license agreement with Clemson University Research Foundation to in-license certain technology and intellectual property relating to ink-jet printing of viable cells. The Company received the exclusive worldwide rights to commercialize products comprising this technology for all fields of use. The Company is required to pay the university royalties ranging from 1.5% to 3% of net sales of covered tissue products and the fair market value of covered tissues transferred internally for use in the Company’s commercial service business, depending on the level of net sales reached each year. The license agreement terminates upon expiration of the patents licensed, which are expected to expire in May 2024, and is subject to certain conditions as defined in the license agreement. Minimum annual royalty payments of $20,000 were due for each of the two years beginning with calendar 2014, and $40,000 per year beginning with calendar 2016. Royalty payments of $40,000 were made in each of the years ended March 31, 2022 and 2021. The annual minimum royalty is creditable against royalties owed during the same calendar year. In addition to the annual royalties noted above, the University is owed 40% of all payments including but not limited to, upfront payments, license fees, issue fees, maintenance fees, and milestone payments received from third parties, including sublicensees, in consideration for sublicensing rights to licensed products. However, per the agreement, in the event that the Company defends the technology by litigation, it can offset any royalties due by legal expenses incurred. As of September 30, 2022, the Company’s legal expenses exceeded royalties owed from the upfront payment and sales-based royalties related to the License Agreement. Therefore, no royalty expense to Clemson University was recorded for the six months ended September 30, 2022. No royalty expense related to sales-based royalties has been recorded to date.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 6. Commitments and Contingencies Legal Matters In addition to commitments and obligations in the ordinary course of business, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected .

Leases

Leases [Abstract]
Leases	Note 7. Leases After the initial adoption of Accounting Standards Codification Topic 842 (“ASC 842”), on an on-going basis, the Company evaluates all contracts upon inception and determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If a lease is identified, the Company will apply the guidance from ASC 842 to properly account for the lease. Operating Leases From October 2019 to July 2021, the Company rented office space in Solana Beach, California. This agreement was a month-to-month contract and could be terminated at-will by either party at any time. As such, the Company concluded that this agreement did not contain a lease and was expensed as incurred (referred to as “rent expense”). Monthly rental payments were approximately $4,000 per month. On November 23, 2020, the Company entered into two lease agreements, pursuant to which the Company temporarily leased approximately 3,212 square feet of lab and office space (the “Temporary Lease”) in San Diego and permanently leased approximately 8,051 square feet of lab and office space (the “Permanent Lease”) in San Diego once certain tenant improvements for the Company’s permanent premises were completed by the landlord and the premises were ready for occupancy. Additionally, on November 17, 2021, the Permanent Lease was amended to add an additional 2,892 square feet of office space in the same building. The Temporary Lease commenced on November 27, 2020 and served as temporary premises until the Permanent Lease was ready for occupancy. The Permanent Lease commenced on December 17, 2021 and is intended to serve as the Company’s permanent premises for approximately sixty-two months. Monthly rental payments will be approximately $40,800 with 3% annual escalators. The Company determined that the Temporary Lease is considered a short term lease under ASC 842 and therefore elected an accounting policy for short term leases to recognize lease payments as an expense on a straight-line basis over the lease term (referred to as “short term lease expense”). Variable lease expenses related to the short term lease, such as payments for additional monthly fees to cover the Company’s share of certain facility expenses (common area maintenance, or CAM) are expensed as incurred. The Company determined that the Permanent Lease is considered an operating lease under ASC 842, and therefore upon the lease commencement date of December 17, 2021, recognized lease liabilities and corresponding right-of-use assets of $2.3 million. The Company records operating lease expense on a straight-line basis over the life of the lease (referred to as “operating lease expense”). Variable lease expenses associated with the Company’s leases, such as payments for additional monthly fees to cover the Company’s share of certain facility expenses (common area maintenance, or CAM) are expensed as incurred. The table below summarizes the Company’s lease liabilities and corresponding right-of-use assets as of September 30, 2022 (in thousands): September 30, 2022 ASSETS Operating lease right-of-use assets $ 1,958 Total lease right-of-use assets $ 1,958 LIABILITIES Current Operating lease liability $ 486 Noncurrent Operating lease liability, net of current portion $ 1,515 Total lease liabilities $ 2,001 Weighted average remaining lease term: 4.33 years Weighted average discount rate: 6 % The Company recorded no rent expense for the three and six months ended September 30, 2022, respectively, and approximately $5,000 and $18,000 for the three and six months ended September 30, 2021, respectively. Variable lease expense was approximately $41,000 and $76,000 for the three and six months ended September 30, 2022, respectively, and approximately $9,000 and $18,000 for the three and six months ended September 30, 2021, respectively. For the three and six months ended September 30, 2022, short term lease expense was $0, respectively, and approximately $39,000 and $78,000 for the three and six months ended September 30, 2021, respectively. Lastly, operating lease expense was approximately $129,000 and $258,000 for the three and six months ended September 30, 2022, respectively, and $0 for the three and six months ended September 30, 2021. Cash flows associated with the Company’s operating lease for the three and six months ended September 30, 2022 was approximately $122,000 and $245,000, respectively. Future lease payments relating to the Company’s operating lease liabilities as of September 30, 2022, are as follows (in thousands): Fiscal year ending March 31, 2023 $ 250 Fiscal year ending March 31, 2024 509 Fiscal year ending March 31, 2025 524 Fiscal year ending March 31, 2026 539 Fiscal year ending March 31, 2027 461 Total future lease payments 2,283 Less: Imputed interest (282 ) Total lease obligations 2,001 Less: Current obligations (486 ) Noncurrent lease obligations $ 1,515

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2022 is derived from the Company’s audited consolidated balance sheet at that date. The unaudited condensed consolidated financial statements include the accounts of Organovo and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2022, as filed with the Securities and Exchange Commission (“SEC”). Operating results for any interim period are not necessarily indicative of the operating results for any other interim period or the Company’s full fiscal year ending March 31, 2023 (see “ Note 1. Description of Business”
Liquidity	Liquidity As of September 30, 2022, the Company had cash and cash equivalents of approximately $13.3 million, short-term investments of $10.0 million, restricted cash of approximately $0.1 million and an accumulated deficit of approximately $314.3 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease agreement for its facilities. The Company also had negative cash flows from operations of approximately $4.6 million during the six months ended September 30, 2022. Through September 30, 2022, the Company has financed its operations primarily through the sale of convertible notes, warrants, the private placement of equity securities, the sale of common stock through public and at-the-market (“ATM”) offerings, and through revenue derived from product and research service-based agreements, collaborative agreements, licenses, and grants. During the three and six months ended September 30, 2022, the Company issued zero shares of its common stock through its ATM facility. The Company believes its cash and cash equivalents on hand will be sufficient to meet its financial obligations for at least the next 12 months of operations. As the Company continues to focus its efforts on drug discovery and development, it will need to raise additional capital to implement this business plan. The Company cannot predict with certainty the exact amount or timing for any future capital raises. If required, the Company may seek to raise additional capital through debt or equity financings, or through some other financing arrangement. However, the Company cannot be sure that additional financing will be available if and when needed, or that, if available, it can obtain financing on terms favorable to its stockholders. Any failure to obtain financing when required will have a material adverse effect on the Company’s business, operating results, financial condition and ability to continue as a going concern.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates used in preparing the unaudited condensed consolidated financial statements include those assumed in revenue recognition and the valuation of stock-based compensation expense. On an ongoing basis, management reviews these estimates and assumptions. Though the impact of the COVID-19 pandemic to its business and operating results presents additional uncertainty, the Company continues to use the best information available to inform its significant accounting estimates.
Investments	Investments Short-term investments consist of investments in debt securities, specifically in U.S. Treasury bills. Any short-term investments that have original maturities of three months or less are classified as cash equivalents on the Condensed Consolidated Balance Sheet. All short-term investments are classified as held-to-maturity, as the Company has both the positive intent and the ability to hold these securities to maturity. Held-to-maturity debt securities are recorded at amortized cost, which approximates fair value. As U.S. Treasury bills are risk-free and will be held until they mature, any declines in fair value are considered temporary. Investments in equity securities consist of investments in the common stock of entities traded in active markets. The Company does not have the ability to exercise significant influence over any entities. Therefore, initial investments are recorded at cost, and are remeasured at fair value as of the balance sheet date. Any gains or losses resulting from the change in fair value is recorded in net income. The investments in equity securities are classified as current assets.
Fair value measurement	Fair value measurement Financial assets and liabilities are measured at fair value, which is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of September 30, 2022, the Company held short-term investments in U.S. Treasury bills. These short-term investments are recorded at amortized cost, which approximates fair value. Please refer to "Note 3. Investments” for further information. As the short-term investments consist of U.S. Treasury bills from active markets, the fair value is measured using level 1 inputs. As of September 30, 2022, the Company held investments in equity securities. As the investments in equity securities consist of common stock from active markets, the fair value is measured using level 1 inputs. The following table presents the activity for investments in equity securities measured at fair value for the six months ended September 30, 2022: Fair Value Measurements Using Quoted Prices in Active Markets (Level 1) Investment in Equity Securities (in thousands) Balance at March 31, 2022 $ — Purchases at cost 1,061 Sales (368 ) Loss on investment in equity securities (75 ) Balance at September 30, 2022 $ 618
Net Loss Per Share	Net Loss Per Share Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“ESPP”), the assumed vesting of restricted stock units (“RSUs”), and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for the three and six months ended September 30, 2022 and 2021 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive.

Revenue recognition	Revenue recognition The Company generates revenues from the licensing of intellectual property. Licenses The Company has entered into a license agreement with a company that includes the following: (i) non-refundable upfront fees and (ii) royalties based on specified percentages of net product sales, if any. At the initiation of the agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606. The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the Company is a principal vs. agent, whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-refundable upfront fees have been considered fixed, while sales-based royalty payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. Please refer to “Note 5: Collaborative Research, Development, and License Agreements” for further information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption.
