Thanks, Alex. Good afternoon, and thank you, everyone, for joining the call. I want to start by acknowledging the challenging situation the COVID-19 pandemic continues to present for so many people. Our thoughts and hearts go out to everyone who has been impacted.
I'm pleased to report that our people are healthy, our supply chain is secure and our business is strong. In a year of extraordinary challenges, 2020 will be a transformative year for Collegium Pharmaceutical. We are on track to achieve our operational objectives in 2020 while concurrently setting the foundation for success in 2021.
I want to take a moment to thank my colleagues at Collegium for their commitment to our mission to become the leader in responsible pain management. I appreciate the effort that they put forth every day and admire their adaptability and resolve.
Business highlights from the third quarter include record net revenue of $79.2 million, which represents an 8.5% increase over the third quarter of 2019; Xtampza ER third quarter net revenue of $32.1 million, which represents a 21% increase versus the third quarter of 2019; total prescriptions were up 19% versus Q3 2019.
As anticipated, Xtampza ER grew at a moderated rate on a sequential basis, and we expect prescriptions to grow at a similar rate in the fourth quarter.
Nucynta franchise net revenue of $47.1 million, which represents a 1% increase versus the third quarter of 2019. Total prescriptions were down 10% versus Q3 2019. But it is worth noting that franchise prescriptions were stable sequentially, and that Nucynta ER TRx share has grown or been stable for 6 consecutive quarters.
OpEx for the quarter was down compared to the third quarter of 2019 and sequentially. We remain committed to leveraging, not growing, Collegium's cost structure in 2020 and beyond. We were profitable on a GAAP basis for the third consecutive quarter, meaningfully increased cash on hand and paid down debt. And we settled the Teva, Xtampza ER ANDA litigation. The settlement contemplates a generic launch no earlier than September 20 -- excuse me, it's September 2033. We believe this settlement confirms the strength of the Xtampza ER patent estate.
Looking forward to 2021. We believe that we have set the foundation upon which Xtampza ER will accelerate beginning in January and upon which sequential annual revenue stability will be achieved with the Nucynta franchise. Our market access team has done a great job executing our portfolio payer strategy.
As it pertains to Xtampza ER, Collegium's market access team has secured additional exclusive ER oxycodone formulary wins that cover approximately 7 million commercial and Medicare Part D lives. The biggest new win is UnitedHealthcare's Medicare Part D AARP PDP preferred business, which is a highly controlled plan and the second largest plan in terms of ER oxycodone prescription. Starting January 1, 2021, Xtampza ER will be the exclusive ER oxycodone for over 92 million commercial and Part D lives.
In addition, the team has secured parity formulary positions that cover approximately 5 million lives. These wins also take effect on January 1, 2021.
From the perspective of managed care pull-through, our commercial team's focus in 2021 will be on 3 buckets of growth: New 2021 wins, 2020 exclusive wins and the 2020 Optum commercial parity win, which covers approximately 17 million lives.
With regards to the Nucynta franchise, we improved rebates with a few plans and opted not to renew some unfavorable contracts that we inherited. We anticipate that the evolution of the payer landscape will have a positive impact on revenue, meaningfully offsetting any pressure on prescriptions.
As the company committed to being the leader of responsible pain management, we will continue to work with payers whenever possible to remove nonclinical barriers to our pain portfolio, which health care providers view favorably and as highly differentiated. The Collegium team is encouraged by, but not satisfied with the progress that we have made thus far in 2020. Every person in our organization is focused on finishing 2020 strong, while simultaneously preparing for a fast start to 2021. I'm confident that we have the people and the portfolio to make it happen.
I will now hand the call over to Paul for a discussion of the financials.
