“In 2017, our focus on operational execution generated significant momentum with Xtampza ER,” said Joe Ciaffoni, Chief Operating Officer of Collegium. “In 2018, the Collegium team is committed to continuing this focus so that patients who require opioid pain management can benefit from abuse-deterrent Xtampza ER, as well as the Nucynta franchise.”

Fourth Quarter and 2017 Financial Results

Net Product Revenues for Xtampza ER were $10.8 million for the quarter ended December 31, 2017 (the “2017 Quarter”) compared to $1.3 million for the quarter ended December 31, 2016 (the “2016 Quarter”).  For the year ended December 31, 2017, Net Product Revenues were $28.5 million compared to $1.7 million for the year ended December 31, 2016. The quarter ended September 30, 2017 included a one-time $4.4 million increase to Net Product Revenue as a result of the Company’s change to the sell-in method of recognizing revenue during the quarter.

Net loss for the 2017 Quarter was $17.4 million, or $0.54 per share (basic and diluted), as compared to net loss of $27.6 million, or $1.02 per share (basic and diluted), for the 2016 Quarter.  Net loss includes stock-based compensation expense of $2.1 million and $1.6 million for the 2017 Quarter and 2016 Quarter, respectively.

Research and development expenses were $2.2 million for the 2017 Quarter compared to $3.3 million for the 2016 Quarter.  The decrease was primarily related to a decrease in product development manufacturing costs of $664,000 and a decrease in research-related regulatory costs of $584,000.

Selling, general and administrative expenses were $25.1 million for the 2017 Quarter compared to $25.4 million for the 2016 Quarter.  The decrease was primarily related to higher sales and marketing costs of $3.4 million in the 2016 Quarter due to the launch of Xtampza and a decrease in Post Marketing Requirements and other regulatory costs of $1.4 million in the 2017 Quarter.  These decreases were partially offset by increased personnel related costs of $2.8 million and a one-time impairment charge of $1.8 million relating to the termination of the Onsolis license and development agreement.

Collegium had cash and cash equivalents of $118.7 million as of December 31, 2017, compared to $153.2 million as of December 31, 2016.  Cash used in operating and investing activities for the 2017 Quarter was $13.5 million.

As of December 31, 2017, there were 32,770,678 common shares outstanding.

Financial Outlook

Based on our current operating plans, we believe that our existing cash resources, together with expected cash inflows from the commercialization of Xtampza ER and the Nucynta franchise will fund our operating expenses, debt service and capital expenditure requirements into 2020.

About Collegium Pharmaceutical, Inc.

Collegium 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.

About Xtampza ER

Xtampza® ER is Collegium’s first product utilizing the DETERx technology platform. Xtampza ER is an abuse-deterrent, extended-release, oral formulation of oxycodone approved by the FDA 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.

LIMITATIONS OF USE

Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve Xtampza ER for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.

Xtampza ER is not indicated as an as-needed (prn) analgesic.

The Full Prescribing Information for Xtampza ER contains the following Boxed Warning:

WARNING:  ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; and CYTOCHROME P450 3A4 INTERACTION; AND RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS

Addiction, Abuse, and Misuse
Xtampza ER exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death.  Assess each patient’s risk prior to prescribing Xtampza ER and monitor all patients regularly for the development of these behaviors or conditions.

Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of Xtampza ER.  Monitor for respiratory depression, especially during initiation of Xtampza ER or following a dose increase.

Accidental Ingestion
Accidental ingestion of even one dose of Xtampza ER, especially by children, can result in a fatal overdose of oxycodone.

Neonatal Opioid Withdrawal Syndrome
Prolonged use of Xtampza ER during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Cytochrome P450 3A4 Interaction
The concomitant use of Xtampza ER with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an

increase in oxycodone plasma concentration. Monitor patients receiving Xtampza ER and any CYP3A4 inhibitor or inducer.

Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants

Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.

· Reserve concomitant prescribing of Xtampza ER and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.

· Limit dosages and durations to the minimum required.

· Follow patients for signs and symptoms of respiratory depression and sedation.

IMPORTANT SAFETY INFORMATION

Xtampza ER is contraindicated in patients with: significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment; known or suspected gastrointestinal obstruction, including paralytic ileus; and hypersensitivity (e.g., anaphylaxis) to oxycodone.

Xtampza ER contains oxycodone, a Schedule II controlled substance. As an opioid, Xtampza ER exposes users to the risks of addiction, abuse, and misuse. As extended-release products, such as Xtampza ER, deliver the opioid over an extended period of time, there is a greater risk for overdose and death due to the larger amount of oxycodone present.

Potential serious adverse events caused by opioids include addiction, abuse, and misuse, life-threatening respiratory depression, neonatal opioid withdrawal syndrome, risks of concomitant use or discontinuation of cytochrome P450 3A4 inhibitors and inducers, risks from concomitant use with benzodiazepines or other CNS depressants, risk of life-threatening respiratory depression in patients with chronic pulmonary disease or in elderly, cachectic, or debilitated patients, adrenal insufficiency, severe hypotension, risks of use in patients with increased intracranial pressure, brain tumors, head injury, or impaired consciousness, risks of use in patients with gastrointestinal conditions, risk of use in patients with seizure disorders, withdrawal, risks of driving and operating machinery, and laboratory monitoring.

The most common AEs (>5%) reported by patients in the Phase 3 clinical trial during the titration phase were:  nausea (16.6%), headache (13.9%), constipation (13.0%), somnolence (8.8%), pruritus (7.4%), vomiting (6.4%), and dizziness (5.7%).
