(the Company) was incorporated in Massachusetts in 1981 and is focused on the development and commercialization of antibody-drug conjugates (ADCs) for the treatment of cancer. The Company has generally incurred operating losses and negative cash flows from operations since inception, incurred a net loss of $163.9 million during the nine months ended September 30, 2022, and had an accumulated deficit of approximately $1.6 billion as of September 30, 2022. The Company has primarily funded these losses through payments received from its collaborations and equity, convertible debt, and other financings. To date, the Company has had no revenues from commercial sales of its own products and management expects to continue to incur substantial operating losses for at least the near term as the Company incurs significant operating expenses related to research and development and potential commercialization of its portfolio.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 6pt 0pt;">As of September 30, 2022, the Company had $309.5 million of cash and cash equivalents on hand. The Company anticipates that its current capital resources will enable it to meet its operational expenses and capital expenditures for more than twelve months after the date these financial statements were issued. The Company expects to raise additional funds through equity, debt, or other financings, or generate revenues from product sales of the Company’s lead product candidate, mirvetuximab soravtansine (MIRV), if approved, as well as revenues from collaborations through a combination of upfront license payments, milestone payments, royalty payments, and research funding to support its planned operating activities. There can be no assurance, however, that the Company will be able to obtain additional equity, debt, or other financing or generate revenues from product sales of MIRV, if approved, or from collaborations on terms acceptable to the Company or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed 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, and/or clinical 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, complexities associated with managing collaboration arrangements, third-party reimbursements, and compliance with governmental regulations.</p> | ||
