(the Company) was incorporated in Massachusetts in 1981 and is focused on the development and commercialization of antibody-drug conjugates (ADCs). On November 14, 2022, the U.S. Food and Drug Administration (FDA) granted accelerated approval for ELAHERE<sup style="color:#231f20;font-size:9pt;line-height:100%;top:0pt;vertical-align:top;">®</sup> (mirvetuximab soravtansine-gynx) for the treatment of adult patients with folate receptor alpha (FRα)-positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. ELAHERE was approved under the FDA's accelerated approval program based on objective response rate (ORR), duration of response (DOR), and safety data from the pivotal SORAYA trial. Continued approval may be contingent upon verification and description of clinical benefit in a confirmatory trial.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 6pt 0pt;">The Company has generally incurred operating losses and negative cash flows from operations since inception, incurred a net loss of $14.5 million during the nine months ended September 30, 2023, and had an accumulated deficit of approximately $1.7 billion as of September 30, 2023. To date, the Company has funded these losses through payments received from its collaborations, equity, convertible debt, and other financings, such as royalty financing transactions and a term loan facility, and, more recently, through<span style="font-size:12pt;"> </span>commercial sales of ELAHERE. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 6pt 0pt;">At September 30, 2023, the Company had $605.5 million of cash and cash equivalents on hand. The Company currently believes that its existing capital resources will be sufficient to fund its operating expenses and capital expenditures for more than twelve months after the date these financial statements were issued. The Company expects to generate additional funds through a combination of commercial sales of ELAHERE and revenues from collaborations, including upfront license payments, milestone payments, royalty payments, and research funding, to support its planned operating activities<span style="background:#ffffff;">; however, </span>such activities may not succeed. If such activities do not raise sufficient funds, the Company may be required to seek additional funding through equity or other financings. The failure of the Company to generate sufficient funds from commercial sales of ELAHERE and collaborations or obtain additional funding through equity or other financings on acceptable terms could have a material adverse effect on the Company’s business, results of operations, and financial condition and require the Company to defer or limit some or all of its research, development, clinical, and/or commercial projects.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 6pt 0pt;">The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, the development by its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, manufacturing and marketing limitations, challenges entering into new collaborations, complexities associated with managing collaboration arrangements, third-party reimbursements, and compliance with governmental regulations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;"></span></p> | ||
