Market Dynamics and Financial Trajectory for Xtampza ER

Introduction

Xtampza ER, an extended-release (ER) formulation of oxycodone, has been a significant player in the opioid market since its introduction in 2016. Developed by Collegium Pharmaceutical, this drug is designed with abuse-deterrent properties to mitigate the risks associated with opioid misuse. Here, we delve into the market dynamics and financial trajectory of Xtampza ER.

Market Position and Growth

Xtampza ER has demonstrated robust growth in the market. The drug's prescriptions increased 50-fold during the study period from its launch, indicating strong adoption by healthcare providers[1].

Prescription Trends

• The number of prescriptions for Xtampza ER has shown consistent growth. For instance, in the first half of 2021, Xtampza ER saw a 7% growth, which was the highest among all branded ER opioids[3].
• The drug's market share has continued to increase, with new prescribers and patients being added to its user base. As of 2021, Xtampza ER's unique prescribers had increased, and its new prescription (NBRx) share exceeded its total prescription (TRx) share[3].

Abuse-Deterrent Features

Xtampza ER is formulated using DETERx® technology, which incorporates microspheres of oxycodone myristate to limit the solubility of oxycodone in water. This design aims to discourage tampering and abuse.

Clinical Evidence

• Studies have shown that Xtampza ER maintains its pharmacokinetic (PK) profile even when manipulated, and it is less preferred when crushed and administered intranasally compared to immediate-release (IR) oxycodone[4].
• Data from the RADARS System indicates that cases of abuse, misuse, and diversion for Xtampza ER were infrequent and did not increase despite the significant rise in prescriptions[1].

Financial Performance

Collegium Pharmaceutical's financial reports provide insight into the financial trajectory of Xtampza ER.

Revenue Growth

• In the third quarter of 2024, Xtampza ER net revenue reached a record $49.5 million, representing a 24% year-over-year increase[2].
• The overall net revenue for Collegium Pharmaceutical in the third quarter of 2024 was $159.3 million, a 17% increase from the same period in 2023[2].

Operating Expenses and EBITDA

• Adjusted operating expenses for Collegium Pharmaceutical increased by 23% year-over-year in the third quarter of 2024, but the company maintained a strong adjusted EBITDA of $105.1 million, an 18% increase from the previous year[2].
• The company's cash balance as of September 30, 2024, was $120.0 million, although this was down from $310.5 million at the end of 2023[2].

Market Access and Coverage

Xtampza ER enjoys broad market access, which has been a key factor in its growth.

Commercial and Medicare Coverage

• As of 2021, Xtampza ER was covered by 84% of commercial plans and 57% of Medicare Part D plans, providing access to a significant portion of the insured population[3].
• The drug is also covered through exclusive and parity contracts for a substantial number of lives, enhancing its market reach[3].

Competitive Landscape

Xtampza ER operates in a competitive opioid market, but its abuse-deterrent features and strong market access have helped it stand out.

Comparison with Other Opioids

• When compared to other ER opioids, Xtampza ER has shown lower rates of abuse and misuse. For example, poison center exposures were greater for IR oxycodone and non-abuse-deterrent ER opioids than for Xtampza ER[1].
• The drug's unique formulation and lower abuse liability have positioned it favorably against competitors like OxyContin, Hysingla ER, and Embeda[1].

Clinical Efficacy

Xtampza ER has demonstrated significant clinical efficacy in managing moderate to severe chronic pain.

Clinical Trials

• In a 12-week clinical trial, Xtampza ER showed a significant reduction in average pain intensity compared to placebo, with a mean difference of 1.85 (P < 0.0001)[4].
• Patients were titrated to a stable and tolerated dose, and the drug maintained its efficacy throughout the trial period[4].

Future Outlook

Given its strong market position, financial performance, and clinical efficacy, Xtampza ER is poised for continued growth.
