Collegium Pharmaceutical, Inc. is a U.S.-based specialty pharmaceutical company focused on commercializing branded products for pain, attention deficit hyperactivity disorder (ADHD), and opioid-induced constipation. Its portfolio includes Xtampza ER, Belbuca, Jornay PM, the Nucynta Products, and Symproic, all sold primarily in the United States. The company’s business model depends on maintaining access to prescribers, payors, and a concentrated wholesale distribution network while managing the regulatory and reputational complexity of opioid and stimulant therapies. Collegium also relies heavily on third-party manufacturing and limited-source active pharmaceutical ingredient supply, which makes supply continuity a central part of its operating model.
