Nature of Business |
Nature of Business | 1. Nature of Business ​ Collegium Pharmaceutical, Inc. (the “Company” or “Collegium”) was incorporated in Delaware in April 2002 and then reincorporated in Virginia in July 2014. The Company has its principal operations in Stoughton, Massachusetts. The Company’s mission is to build a leading, diversified specialty pharmaceutical company committed to improving the lives of people living with serious medical conditions. The Company’s portfolio includes Xtampza ER, Nucynta ER and Nucynta IR (collectively the “Nucynta Products”), Belbuca, and Symproic. ​ Xtampza ER, an abuse-deterrent, oral formulation of oxycodone, was approved by the U.S. Food and Drug Administration (“FDA”) in April 2016 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. The Company commercially launched Xtampza ER in June 2016. ​ The Nucynta Products are extended-release (“ER”) and immediate-release (“IR”) formulations of tapentadol. Nucynta ER 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 indicated for the management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate in adults. The Company began shipping and recognizing product sales on the Nucynta Products in January 2018 and began marketing the Nucynta Products in February 2018. ​ On March 22, 2022 (the “Acquisition Date”), the Company acquired BioDelivery Sciences International, Inc. (“BDSI”), a specialty pharmaceutical company working to deliver innovative therapies for individuals living with serious and debilitating chronic conditions, pursuant to an Agreement and Plan of Merger, dated as of February 14, 2022, by and among the Company, Bristol Acquisition Company Inc., the Company’s wholly owned subsidiary, and BDSI (the “BDSI Acquisition”). Upon closing, the Company acquired the Belbuca and Symproic products. Belbuca is a buccal film that contains buprenorphine, a Schedule III opioid, and was approved by the FDA in October 2015 for use in patients with pain severe enough to require daily, around-the-clock, long-term opioid treatment for which alternative options are inadequate. Symproic was approved by the FDA in March 2017 for the treatment of opioid-induced constipation (“OIC”) in adult patients with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g., weekly) opioid dosage escalation. The Company began shipping and recognizing product sales related to Belbuca and Symproic in March 2022. ​ The Company’s operations are subject to certain risks and uncertainties. The principal risks include inability to continue successfully commercializing products, changing market conditions for products and development or introduction of competing products, changing regulatory environment and reimbursement landscape, product-related litigation, manufacture of adequate commercial inventory, inability to secure adequate supplies of active pharmaceutical ingredients, key personnel retention, protection of intellectual property, and patent infringement litigation. ​ The Company believes that its cash and cash equivalents as of September 30, 2023, 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 under its current business plan for at least one year from the date the consolidated financial statements were issued.
