Accounting Policies [Abstract] | |
Organization and Summary of Significant Accounting Policies | NOTE 1 — ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of the Business Molecular Templates, Inc. (the “Company”) is a clinical stage biopharmaceutical company formed in 2001, with a biologic therapeutic platform for the development of novel targeted therapeutics for cancer and other serious diseases, headquartered in Austin, Texas. The Company’s focus is on the research and development of therapeutic compounds for a variety of cancers. The Company operates its business as a single segment, as defined by U.S. generally accepted accounting principles (“U.S. GAAP”). In March 2020, the outbreak of COVID-19 caused by a novel strain of the coronavirus was recognized as a pandemic by the World Health Organization. While the COVID-19 pandemic has not had a material adverse impact on the Company’s operations to date, the full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain. Additionally, the duration of the pandemic (including any resurgences), impact of the new COVID-19 variants, the rollout of COVID-19 vaccines, new information that may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others, could have an adverse impact on the Company. Refer to Item 1A. “Risk Factors” in this Quarterly Report on Form 10-Q for a complete description of risks. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of the Company and its wholly owned subsidiary and reflect the elimination of intercompany accounts and transactions. The preparation of condensed consolidated financial statements requires management to make estimates and assumptions that affect the recorded amounts reported therein. A change in facts or circumstances surrounding the estimates could result in a change to estimates and impact future operating results. Certain accounts in the prior financial statements have been reclassified for comparative purposes to conform to the presentation in the current financial statements. These reclassifications have no material effect on previously reported financials. The unaudited condensed consolidated financial statements and related disclosures have been prepared with the presumption that users of the interim unaudited condensed consolidated financial statements have read or have access to the audited consolidated financial statements for the preceding fiscal year. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 29, 2022. Liquidity At March 31, 2022, the Company had cash, cash equivalents, and marketable securities of $124.5 million. The Company has devoted substantially all of our resources to developing our ETB candidates and platform technology, building our intellectual property portfolio, developing our supply chain, conducting business planning, raising capital and providing for general and administrative support for these operations. The Company expects that existing cash, cash equivalents and marketable securities will enable it to fund operating expenses and capital expenditure requirements to the end of 2023. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2022, as compared to the significant accounting policies disclosed in Note 1, “Summary of Significant Accounting Policies”, to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Cash and Cash Equivalents The Company considers temporary investments having original maturities of three months or less from date of purchase to be cash equivalents. Restricted cash is recorded in other assets, based on when the restrictions expire. Other assets include $2.7 million of restricted cash at March 31, 2022 related to letters of credit in lieu of a cash deposit for the Company’s leases . Fair Value Measurement The Company accounts for its marketable securities in accordance with ASC 820 “Fair Value Measurements and Disclosures.” Level 1 —Quoted prices in active markets for identical assets or liabilities. Level 2 —Observable inputs other than Level 1 prices 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. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. For Level 2 securities that have market prices from multiples sources, a “consensus price” or a weighted average price for each of these securities can be derived from a distribution-curve-based algorithm which includes market prices obtained from a variety of industrial standard data providers (e.g. Bloomberg), security master files from large financial institutions, and other third-party sources. Level 2 securities with short maturities and infrequent secondary market trades are typically priced using mathematical calculations adjusted for observable inputs when available. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to concentrations of risk consist principally of cash and cash equivalents, investments, long term debt and accounts receivable. The Company’s cash and cash equivalents are with two major financial institutions in the United States. The Company performs an ongoing credit evaluation of its strategic partners’ financial conditions and generally does not require collateral to secure accounts receivable from its strategic partners. The Company’s exposure to credit risk associated with non-payment will be affected principally by conditions or occurrences within Millennium Pharmaceuticals, Inc., a wholly owned subsidiary of Takeda Pharmaceutical Company Ltd. (“Takeda”), Vertex Pharmaceuticals Incorporated (“Vertex”) and Bristol Myers Squibb Company (“Bristol Myers Squibb” or “BMS”) Drug or biologic candidates developed by the Company may require approvals or clearances from the U.S. Food and Drug Administration (“FDA”) or international regulatory agencies prior to commercial sales. There can be no assurance that the Company’s drug or biologic candidates will receive any of the required approvals or clearances. If the Company were to be denied approval or clearance or any such approval or clearance were to be delayed, it would have a material adverse impact on the Company. Recently Issued Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Subtopic 470-20: Debt with Conversion and Other Options and Subtopic 815-40: Derivatives and Hedging - Contracts in Entity’s Own Equity). The new guidance simplifies accounting for convertible instruments by removing major separation models, removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. The amendment is effective for the Company for fiscal years beginning after December 15, 2023. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements. In November 2021, the FASB issued ASU No. 2021-10, “Government Assistance: Disclosures by Business Entities about Government Assistance”. The amendments in this Update improve financial reporting by requiring disclosures that increase the transparency of transactions with a government. The amendments require the following annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy (i) the type of transaction, (ii) the accounting for the transaction, and (iii) the effect of the transaction on the entity’s financial statements. The Company adopted this standard as of January 1, 2022, using a prospective approach and it did not have a material impact on the Company’s financial statements and related disclosures |

Earnings Per Share [Abstract] | |
Net Loss Per Common Share | NOTE 2 — NET LOSS PER COMMON SHARE Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period utilizing the two-class method. Preferred Stock Shareholders participate equally with Common Stock Shareholders in earnings, but do not participate in losses, and are excluded from the basic net loss calculation. Diluted net loss per share is computed by giving effect to all potential dilutive common shares, including outstanding options, warrants and convertible preferred stock. More specifically, at March 31, 2022 and March 31, 2021, stock options, warrants and, if converted, preferred stock totaling approximately 12,999,361 and 12,144,173 common shares, respectively, were excluded from the computation of diluted net loss per share as their effect would have been anti-dilutive. |

In April 2021, the Company received a notice of termination from Takeda for the Takeda Development and License Agreement. F As of the same date, the Company assumed full rights to MT-0169, including full control of MT-0169 clinical development, per the terms of the terminated Takeda Development and License Agreement. Following the transfer of the full MT-0169 rights to the Company, the Company may owe low-single digit royalties on future net sales of MT-0169 to Takeda as well as to certain third-party licensors. The Company may also owe certain third-party licensors potential aggregate clinical and regulatory milestone payments of up to $22.25 million. The Company recognized revenue using a cost-based input measure. In applying the cost-based input method of revenue recognition, the Company used actual costs incurred relative to budgeted costs expected to be incurred for the combined performance obligation. These costs consist primarily of internal employee efforts and third-party contract costs. Revenue was recognized based on actual costs incurred as a percentage of total budgeted costs as the Company completes its performance obligation over the estimated service period. Takeda Multi-Target Agreement In June 2017, the Company entered into a Multi-Target Collaboration and License Agreement with Millennium Pharmaceuticals, Inc., a wholly owned subsidiary of Takeda (the “Takeda Multi-Target Agreement”), in which the Company agreed to collaborate with Takeda to identify and generate ETBs, against two targets designated by Takeda. I n March 2022, following the Company’s request to bring the agreement to an end, the Company and Takeda mutually agreed to terminate the Takeda Multi-Target Agreement. As a result of the termination, the Company regained full rights to pursue the targets worked on under the Takeda Multi-Target Agreement. There are no ongoing activities or economic obligations in connection with the Takeda Multi-Target Agreement. As of March 31, 2022, t he Company received cumulative payments of $5.0 million from Takeda pursuant to the Takeda Multi-Target Agreement. Prior to the termination, the Company also had the opportunity to receive payments of the following: • $ 30.0 million in aggregate through the exercise of the option to license ETBs. • Up to approximately $ 397.0 million in clinical development milestone payments for achievement of development milestones and regulatory approval of collaboration products under the Takeda Multi-Target Agreement. • Up to $ 150.0 million in commercial milestone payments for achievement of pre-specified sales milestones related to net sales of all collaboration products under the Takeda Multi-Target Agreement. • Tiered royalty payments of a mid-single to low-double digit percentage of net sales of any licensed ETBs, subject to certain reductions. • Up to $ 10.0 million in certain contingency fees. At March 31, 2022 there was no deferred revenue related to the performance obligation and at December 31, 2021, deferred revenue was $2.6 million. Vertex Collaboration Agreement In November 2019, the Company entered into a Master Collaboration Agreement (the “Vertex Collaboration Agreement”) with Vertex Pharmaceuticals Incorporated (“Vertex”), to perform strategic research leveraging the Company’s engineered toxin body (“ETB”) technology platform to discover and develop novel targeted biologic therapies for applications outside of oncology. In October 2021, the Company received a notice of termination from Vertex for the Vertex Collaboration Agreement. The termination of the Vertex Collaboration Agreement was effective in October 2021. There are no ongoing activities or economic obligations in connection with the Vertex Collaboration Agreement. Vertex paid the Company an upfront payment of $38.0 million, consisting of $23.0 million in cash and a $15.0 million equity investment pursuant to a Share Purchase Agreement (the “SPA”). In addition to the upfront payments, the Company was also eligible to receive an additional $22.0 million through the exercise of the options to license ETB products or to add an additional target. The Company would have been entitled to receive, subject to certain reductions, tiered mid-single digit royalties as percentages of calendar year net sales, if any, on any licensed product. The Company also had the opportunity, for each target under the Vertex Collaboration Agreement The Company would have been entitled to receive, subject to certain reductions, tiered mid-single digit royalties as percentages of calendar year net sales, if any, on any licensed product. With the termination of the agreement, the Company’s performance obligations under the Vertex Collaboration Agreement Bristol Myers Squibb Collaboration Agreement In February 2021, the Company, entered into a Collaboration Agreement (the “BMS Collaboration Agreement”), as amended, with Bristol Myers Squibb Company (“Bristol Myers Squibb”) to perform strategic research collaboration leveraging the Company’s ETB technology platform to discover and develop novel products containing ETBs directed to multiple targets. Pursuant to the terms of the BMS Collaboration Agreement, the Company granted Bristol Myers Squibb a series of exclusive options to obtain one or more exclusive licenses under the Company’s intellectual property to exploit products containing ETBs directed against certain targets designated by Bristol Myers Squibb. Bristol Myers Squibb paid the Company an upfront payment of $70.0 million. In addition to the upfront payment, the Company may receive near term and development and regulatory milestone payments of up to $874.5 million. The Company will also be eligible to receive up to an additional $450.0 million in payments upon the achievement of certain sales milestones, and subject to certain reductions, tiered royalties ranging from mid-single digits up to mid-teens as percentages of calendar year net sales, if any, on any licensed product. The Company will be responsible for conducting the research activities through the designation, if any, of one or more development candidates. Upon the exercise of its option for a development candidate, Bristol Myers Squibb will be responsible for all development, manufacturing, regulatory and commercialization activities with respect to that development candidate. Unless earlier terminated, the BMS Collaboration Agreement will expire (i) on a country-by-country basis and licensed product-by-licensed product basis, on the date of expiration of the royalty payment obligations under the BMS Collaboration Agreement with respect to such licensed product in such country and (ii) in its entirety upon the earlier of (a) the expiration of the royalty payment obligations under the BMS Collaboration Agreement with respect to all licensed products in all countries or (b) upon Bristol Myers Squibb’s decision not to exercise any option on or prior to the applicable option deadlines. Bristol Myers Squibb has the right to terminate the BMS Collaboration Agreement for convenience upon prior written notice to the Company. Either party has the right to terminate the BMS Collaboration Agreement (a) for the insolvency of the other party or (b) subject to specified cure periods, in the event of the other party’s uncured material breach. The Company has the right upon prior written notice to terminate the BMS Collaboration Agreement in the event that Bristol Myers Squibb or any of its affiliates asserts a challenge against the Company’s patents. The Company identified multiple performance obligations at the inception of the BMS Collaboration Agreement consisting of research and development services and material rights related to additional developmental targets. The transaction price of $70.0 million was allocated to the performance obligations based upon their relative stand-alone selling price and will be recognized over time as the underlying research and development services are performed. The Company recognizes revenue for research and development services under the BMS Collaboration Agreement using a cost-based input measure. In applying the cost-based input method of revenue recognition, the Company will use actual costs incurred relative to budgeted costs expected to be incurred. These costs consist primarily of internal employee efforts and third-party contract costs. Revenue is recognized based on actual costs incurred as a percentage of total budgeted costs as the Company completes its performance obligation over the estimated service period. The Company had $34.3 million and $32.8 million of deferred revenue, current, at March 31, 2022 and December 31, 2021 respectively, related to the BMS Collaboration Agreement.

This cost will be recorded as compensation expense on a ratable basis over the remaining weighted average requisite service period of approximately 2.76 years. Valuation Assumptions The Company estimated the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. This fair value is being amortized ratably over the requisite service periods of the awards, which is generally the vesting period. The fair value of employee stock options was estimated using the following weighted-average assumptions: Three Months Ended March 31, 2022 2021 Employee Stock Options: Risk-free interest rate 2.02 % 0.87 % Expected term (in years) 6.08 6.08 Dividend yield — — Volatility 90.41 % 113.12 % Weighted-average fair value of stock options granted $ 2.07 $ 11.62 Equity Incentive Plans These plans consist of the 2018 Equity Incentive Plan, the 2014 Equity Incentive Plan, as amended; the 2004 Amended and Restated Equity Incentive Plan; and the Amended and Restated 2004 Employee Stock Purchase Plan.

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of the Company and its wholly owned subsidiary and reflect the elimination of intercompany accounts and transactions. The preparation of condensed consolidated financial statements requires management to make estimates and assumptions that affect the recorded amounts reported therein. A change in facts or circumstances surrounding the estimates could result in a change to estimates and impact future operating results. Certain accounts in the prior financial statements have been reclassified for comparative purposes to conform to the presentation in the current financial statements. These reclassifications have no material effect on previously reported financials. The unaudited condensed consolidated financial statements and related disclosures have been prepared with the presumption that users of the interim unaudited condensed consolidated financial statements have read or have access to the audited consolidated financial statements for the preceding fiscal year. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 29, 2022. |
Liquidity | Liquidity At March 31, 2022, the Company had cash, cash equivalents, and marketable securities of $124.5 million. The Company has devoted substantially all of our resources to developing our ETB candidates and platform technology, building our intellectual property portfolio, developing our supply chain, conducting business planning, raising capital and providing for general and administrative support for these operations. The Company expects that existing cash, cash equivalents and marketable securities will enable it to fund operating expenses and capital expenditure requirements to the end of 2023. |
Significant Accounting Policies | Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2022, as compared to the significant accounting policies disclosed in Note 1, “Summary of Significant Accounting Policies”, to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers temporary investments having original maturities of three months or less from date of purchase to be cash equivalents. Restricted cash is recorded in other assets, based on when the restrictions expire. Other assets include $2.7 million of restricted cash at March 31, 2022 related to letters of credit in lieu of a cash deposit for the Company’s leases . |
Fair Value Measurement | Fair Value Measurement The Company accounts for its marketable securities in accordance with ASC 820 “Fair Value Measurements and Disclosures.” Level 1 —Quoted prices in active markets for identical assets or liabilities. Level 2 —Observable inputs other than Level 1 prices 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. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. For Level 2 securities that have market prices from multiples sources, a “consensus price” or a weighted average price for each of these securities can be derived from a distribution-curve-based algorithm which includes market prices obtained from a variety of industrial standard data providers (e.g. Bloomberg), security master files from large financial institutions, and other third-party sources. Level 2 securities with short maturities and infrequent secondary market trades are typically priced using mathematical calculations adjusted for observable inputs when available. |
Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to concentrations of risk consist principally of cash and cash equivalents, investments, long term debt and accounts receivable. The Company’s cash and cash equivalents are with two major financial institutions in the United States. The Company performs an ongoing credit evaluation of its strategic partners’ financial conditions and generally does not require collateral to secure accounts receivable from its strategic partners. The Company’s exposure to credit risk associated with non-payment will be affected principally by conditions or occurrences within Millennium Pharmaceuticals, Inc., a wholly owned subsidiary of Takeda Pharmaceutical Company Ltd. (“Takeda”), Vertex Pharmaceuticals Incorporated (“Vertex”) and Bristol Myers Squibb Company (“Bristol Myers Squibb” or “BMS”) Drug or biologic candidates developed by the Company may require approvals or clearances from the U.S. Food and Drug Administration (“FDA”) or international regulatory agencies prior to commercial sales. There can be no assurance that the Company’s drug or biologic candidates will receive any of the required approvals or clearances. If the Company were to be denied approval or clearance or any such approval or clearance were to be delayed, it would have a material adverse impact on the Company. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Subtopic 470-20: Debt with Conversion and Other Options and Subtopic 815-40: Derivatives and Hedging - Contracts in Entity’s Own Equity). The new guidance simplifies accounting for convertible instruments by removing major separation models, removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. The amendment is effective for the Company for fiscal years beginning after December 15, 2023. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements. In November 2021, the FASB issued ASU No. 2021-10, “Government Assistance: Disclosures by Business Entities about Government Assistance”. The amendments in this Update improve financial reporting by requiring disclosures that increase the transparency of transactions with a government. The amendments require the following annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy (i) the type of transaction, (ii) the accounting for the transaction, and (iii) the effect of the transaction on the entity’s financial statements. The Company adopted this standard as of January 1, 2022, using a prospective approach and it did not have a material impact on the Company’s financial statements and related disclosures |
