Organization, Consolidation and Presentation of Financial Statements [Abstract]
Liquidity and Going Concern	Liquidity and Going Concern The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The accompanying consolidated financial statements do not reflect any adjustments relating to the recoverability and reclassifications of assets and liabilities that might be necessary if the Company is unable to continue as a going concern. The Company expects its costs and expenses to increase as it continues to develop its product candidates and progress its current and planned clinical programs. Pursuant to the requirements of Accounting Standard Codification ("ASC") 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date these financial statements are issued, but will consider such plans if (1) it is probable that the plans will be effectively implemented within one year after the date the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant condition or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the consolidated financial statements are issued. Certain elements of the Company’s operating plan to alleviate the conditions that raise substantial doubt are outside of the Company’s control and cannot be included in management’s evaluation under the requirements of Accounting Standard Codification (ASC) 205-40. Since inception, the Company has incurred recurring losses and negative cash flows from operations and has an accumulated deficit of $138.6 million as of December 31, 2021. During the year ended December 31, 2021, the Company incurred a net loss of $20.7 million and used $26.0 million of cash in operations. The Company continues to expect to generate operating losses and negative cash flows for the next few years and will need additional funding to support its planned operating activities through profitability. The transition to profitability is dependent upon the successful development, approval, and commercialization of the Company's product candidates and the achievement of a level of revenues adequate to support its cost structure. As of December 31, 2021, the Company had cash and cash equivalents of $21.4 million. The Company expects its cash and cash equivalents will not be sufficient to fund its current planned operations for at least the next twelve months from the date of issuance of these financial statements. These conditions give rise to a substantial doubt over the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. On April 16, 2021, the Company entered into a Controlled Equity OfferingSM Sales Agreement, or the Sales Agreement, with Cantor Fitzgerald & Co., or the Agent. From time to time during the term of the Sales Agreement, the Company may offer and sell shares of common stock having an aggregate offering price up to a total of $50.0 million in gross proceeds. The Agent will collect a fee equal to 3% of the gross sales price of all shares of common stock sold. Shares of common stock sold under the Sales Agreement are offered and sold pursuant to the Company's registration statement on Form S-3, which was filed with the SEC on April 16, 2021 and declared effective on April 29, 2021. During the year ended December 31, 2021, the Company sold 786,927 shares of common stock pursuant to the Sales Agreement at an average price of $12.04 per share for aggregate net proceeds of approximately $9.0 million. Other than the Sales Agreement, the Company currently does not have any commitments to obtain additional funds. During the year ended December 31, 2021, the Company received $3.1 million from the exercise of warrants to acquire shares of the Company's common stock. During the year ended December 31, 2021, the Company received $2.0 million from milestones achieved pursuant to the 3DMed Agreement (See Note 11). In January 2022, the Company announced that an IND application for a small Phase I clinical trial investigating safety of GPS in China was accepted by China's National Medical Products Administration ("NMPA"). 3D Medicines expects to initiate the trial by mid-2022 and will be responsible for all expenses related to executing the trial in China. On March 30, 2022, the IND was approved by the NMPA triggering a $1.0 million milestone payment to the Company which is expected to be received in the second quarter of 2022. The current clinical development plan provides for initiation of a Phase II clinical trial following receipt of satisfactory safety data from the Phase I study; the initiation of the Phase II study will also trigger a milestone payment to the Company which is expected in the second half of 2022. Total remaining potential milestone payments to the Company under the 3DMed Agreement total $192.5 million, not including future royalties. The Company will require substantial additional financing to commercially develop any current or future product candidates. Alternatively, the Company will be required to scale back its plans and place certain activities on hold. Other than the Sales Agreement, the Company currently does not have any commitments to obtain additional funds, and may be unable to obtain sufficient funding in the future on acceptable terms, if at all. The Company's management continues to evaluate different strategies to obtain the required funding for future operations. These strategies may include utilizing the Sales Agreement, public and private placements of equity and/or debt securities, payments from potential strategic research and development collaborations, and licensing and/or marketing arrangements with pharmaceutical companies. Additionally, the Company continue to pursue discussions with global and regional pharmaceutical companies for licensing and/or co-development rights to its product candidates. There can be no assurance that these future funding efforts will be successful. If the Company cannot obtain the necessary funding, the Company will need to delay, scale back or eliminate some or all of its research and development programs; consider other various strategic alternatives, including a merger or sale; or cease operations.
