Liquidity And Capital Resources |
LIQUIDITY AND CAPITAL RESOURCES | 2) LIQUIDITY AND CAPITAL RESOURCES The Company has incurred significant operating losses and has an accumulated deficit as a result of its efforts to develop product candidates, including conducting clinical trials and providing general and administrative support for operations. As of June 30, 2024, the Company had an unrestricted cash balance of approximately $2.6 million and an accumulated deficit of approximately $199.2 million. For the three and six months ended June 30, 2024, the Company incurred a net loss of $5.5 million and $12.2 million, respectively, and for the six months ended June 30, 2024, the Company used cash of $6.0 million in operating activities. In October 2022, the Company entered into a sublease for approximately 45,500 square feet of office and laboratory space in Somerville, Massachusetts. Pursuant to the sublease, the Company delivered to the sublessor a security deposit in the form of a letter of credit in the amount of $4.1 million. The letter of credit was issued by the Company’s commercial bank, which required that the Company cash collateralize the letter of credit by depositing $4.1 million in a restricted cash account with such bank. On August 5, 2024, the sublessor drew down on the letter of credit for the full $4.1 million to cover past due rent, plus penalties and interest. On August 9, 2024 the Company and the sublessor entered into a sublease termination agreement, effective August 31, 2024. See Note 8 for additional information regarding the sublease, and see Note 17 for additional information regarding the sublease termination agreement. In April 2023, the Company entered into a standby equity purchase agreement (the “SEPA”) and a registration rights agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park committed to purchase up to $10.0 million of the Company’s common stock in an “equity line” financing arrangement. During the year ended December 31, 2023, the Company issued and sold approximately 214,000 shares of common stock under the SEPA for gross proceeds of $0.3 million. No shares have been sold under the SEPA during the three and six months ended June 30, 2024. In July and December 2023, the Company received $16.5 million in aggregate gross proceeds from the issuance of convertible notes and in January 2024 received an additional $1.4 million in gross proceeds from the issuance of additional convertible notes. See Note 5 for additional information regarding these financings. In connection with preparing the accompanying condensed consolidated financial statements as of and for the three and six months ended June 30, 2024, the Company’s management concluded that there is substantial doubt regarding the Company’s ability to continue as a going concern because it does not expect to have sufficient cash or working capital resources to fund operations for the twelve-month period subsequent to the issuance date of these condensed consolidated financial statements. The Company will need to raise additional capital, which could be through the sales of shares of its common stock under the SEPA, public or private equity offerings, debt financings, out-licensing the Company’s intellectual property, strategic partnerships or other means. Other than the SEPA, the Company currently has no arrangements for capital, and no assurances can be given that it will be able to raise capital when needed, on acceptable terms, or at all. The accompanying condensed 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 condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to the Company’s ability to continue as a going concern.
