Nature of Business
Nature of Business	1. Nature of Business Collegium Pharmaceutical, Inc. (the “Company”) was incorporated in Delaware in April 2002 and then reincorporated in Virginia in July 2014. The Company has its principal operations in Canton, Massachusetts. The Company is a specialty pharmaceutical company focused on becoming the leader in responsible pain management by developing and commercializing innovative, differentiated products for patients suffering from pain. The Company’s first product, Xtampza ER®, or Xtampza, is an abuse-deterrent, extended-release, oral formulation of oxycodone, a widely prescribed opioid medication. In April 2016, the U.S. Food and Drug Administration (“FDA”) approved the Company’s new drug application (“NDA”) filing for Xtampza for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. In June 2016, the Company announced the commercial launch of Xtampza. In December 2017, the Company and its wholly owned subsidiary, Collegium NF, LLC (“Collegium NF”) entered into a Commercialization Agreement with Depomed, Inc. (“Depomed”), pursuant to which Depomed agreed to grant a sublicense of certain of its intellectual property related to Nucynta ER and IR products (the “Nucynta Products”) to the Company for commercialization of the Nucynta Products in the United States. On January 9, 2018, the parties amended the Commercialization Agreement (as amended, the “Commercialization Agreement”) and consummated the transactions contemplated thereby. Nucynta ER is an extended release formulation of tapentadol that is indicated for the management of pain severe enough to require daily, around the clock, long term opioid treatment, including neuropathic pain associated with diabetic peripheral neuropathy in adults, and for which alternate treatment options are inadequate. Nucynta IR is an immediate release formulation of tapentadol that is indicated for the management of moderate to severe acute pain in adults. The Company began shipping and recognizing product sales on the Nucynta Products on January 9, 2018 and began commercial promotion of the Nucynta Products in February 2018. The assets and liabilities assumed by the Company in connection with the Commercialization Agreement are further described in Note 7. The Company’s operations are subject to certain risks and uncertainties. The principal risks include inability to successfully commercialize products, changing market conditions for products and product candidates (including development of competing products), changing regulatory environment and reimbursement landscape, negative outcome of clinical trials, inability or delay in completing clinical trials or obtaining regulatory approvals, key personnel retention and protection of intellectual property, patent infringement litigation and the availability of additional capital financing on terms acceptable to the Company. The Company has experienced net losses and negative cash flows from operating activities since its inception, and, as of March 31, 2018 had an accumulated deficit of $316,701. The Company expects to continue to incur net losses in the near future. A successful transition to profitable operations is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. The Company believes that its cash and cash equivalents at March 31, 2018, together with expected cash inflows from the commercialization of its products, will enable the Company to fund its operating expenses, debt service and capital expenditure requirements into 2020. The Company may never achieve profitability, and unless and until it does, the Company will continue to need to raise additional cash. Management intends to fund future operations through additional private or public debt or equity offerings and may seek additional capital through arrangements with strategic partners or from other sources. If the Company is unable to obtain financing or increase profitability, the related lack of liquidity will have a material adverse effect on the Company’s operations and future prospects.
