Thanks, Paul. Xtampza ER finished 2019 with momentum and as a result of 20 new exclusive ER oxycodone formulary wins impacting over 35 million predominantly commercial lives, is positioned for its next phase of accelerated growth in the first half of 2020. Xtampza ER achieved all-time highs for total prescriptions and market share in a quarter. In the fourth quarter, total prescriptions grew to 124,067, up 36.6% versus the fourth quarter of 2018.Xtampza ER exited 2019 with a 19% share of the ER oxycodone market, up 7 percentage points from December 2018. In the fourth quarter, there were 13,406 unique prescribers of Xtampza ER, an increase of 31% versus the fourth quarter of 2018. Importantly, the productivity of the prescriber base increased every quarter in 2019. In the fourth quarter, the average total prescriptions per prescriber increased to a new high of 9.3. Xtampza ER ended 2019 as the Number 1 prescribed ER oxycodone in 22 accounts of 29 accounts in which it was exclusive. Within exclusive accounts, Xtampza ER's market share of the ER oxycodone market grew to 63% in the fourth quarter. Based off of quantitative market research conducted in the fall of 2019, 51% of our targeted healthcare providers intend to prescribe more Xtampza ER over the next 12 months compared to 60% that intend to prescribe less OxyContin.Nucynta franchise total prescriptions were 128,383 in the fourth quarter of 2019, representing a sequential decline of 2%. In the fourth quarter, Nucynta ER new-to-brand share grew to 6%, its highest level in 2019 and total prescription share was stable for the third consecutive quarter.In 2020, our commercial priorities are clear, grow Xtampza ER and moderate the decline of the Nucynta franchise. The market access position for Xtampza ER is strong and broad with Xtampza ER being covered for 95% of commercial lives and 50% of Part D lives. And with 20 new exclusive formulary position that are in place as of January 1, Xtampza ER is the exclusive ER oxycodone for approximately 40% of commercial and Part D covered lives. Xtampza ER has surpassed OxyContin in terms of both breadth and strength of market access. Our primary focus for the first half of 2020 will be on aggressively pulling through Xtampza ER's 49 exclusive ER oxycodone formulary positions, 20 of which went into effect on January 1, 2020. Concurrently, we'll be pulling through Xtampza ER's overall broad market access.Early on in 2020, we've seen strong growth in Xtampza ER new-to-brand volume and ER oxycodone market share. New-to-brand ER oxycodone market share for Xtampza ER was 37% the week ending January 31, up from 23% the last week of December 2019. In the month of January, Xtampza ER's TRx share of the ER oxycodone market grew by 2% to 21%. We are encouraged by these early indicators, but recognize that we have a lot of work to do.Tapentadol is a molecule that our targeted healthcare providers view favorably relative to all other branded ER opioids and Nucynta ER is differentiated as the only extended-release opioid indicated for pain associated with diabetic peripheral neuropathy. Although we aspire to grow the Nucynta franchise in 2020, we anticipate the total prescriptions will be pressured. Our focus will be on driving brand awareness and pulling through Nucynta's broad market access position.2020 is going to be a transformative year for Collegium. I look forward to updating you on our progress as the year progresses.With that, I'll turn the call back to Joe.
