Thank you, Peter. Good afternoon, everyone and thanks for taking the time to join us as we discuss our 2022 third quarter results. During the first nine months of 2022, we continued to execute on our long-term growth strategy, focusing on successfully transitioning from our legacy and mature products to our growth products. Products acquired or launched since 2020 accounted for 42% of our total net product sales, slightly surpassing Trokendi XR's net product sales contribution in the third quarter. For the first nine months of this year, total revenues were $500 million, representing a 19% increase over the same period last year. Adjusted non-GAAP operating earnings of $91 million, reflected continued significant investment in Qelbree. During the third quarter, the company increased its commercial efforts, including a direct-to-consumer campaign to build more momentum behind the adult launch and to support the important back-to-school season. Qelbree’s launch continues to progress well with increased momentum in prescription growth and shipments due to the launch in the adult population and the back-to-school season. And during the third quarter of 2022, total IQVIA prescriptions for Qelbree reached 94,328, representing an increase of 50%, compared to the second quarter of 2022. Prescriptions in the most recent month of September reached 34,633, the highest monthly total since the launch. Based on weekly IQVIA prescription data by age, at the end of the third quarter, adult prescriptions represented approximately 23% of total Qelbree’s prescriptions. During the third quarter, which was the first full quarter after the launch in adults, adult prescriptions grew by 77% and pediatric prescriptions showed solid growth of 43%. Qelbree continues to expand its base of prescribers with over 14,265 prescribers in the third quarter of 2022, up from 9,276 prescribers in the second quarter of 2022. We continue to receive positive feedback…

Thank you, Jack. Good afternoon, everyone. As I review our third quarter 2022 results, please refer to today's press release. Total revenue for the third quarter 2022 was $177.4 million, a 19% increase, compared to $148.5 million in the same quarter last year. Total revenue in the third quarter of 2022 was comprised of net product sales of $172.7 million and royalty revenue of $4.7 million. The third quarter revenue is the highest quarterly revenue in the company’s history. The increase was primarily due to net product sales of GOCOVRI from the acquisition of Adamas in November of 2021 and growth in net product sales of Qelbree and Oxtellar XR. For the third quarter of 2022, combined R&D and SG&A expenses were $131.9 million, as compared to $91.7 million for the same period in 2021. This increase was primarily due to activities to support the launch of Qelbree and the investment in the Qelbree direct to consumer campaign. As Jack mentioned, the DTC campaign and associated expenditures were substantially complete in the third quarter of 2022. Amortization of intangible assets for the third quarter of 2022 was 20.6 million, compared to 6 million for the same period in 2021. The increase is due to the Adamas acquisition. Operating loss on a GAAP basis for the third quarter of 2022 was 1.5 million as compared to an operating gain of 32.6 million in the same period of 2021. The decrease in GAAP operating earnings, which was expected is primarily attributable to higher expenses to support the launch of Qelbree, the investment in the DTC campaign, and the aforementioned amortization of intangibles associated with the Adamas acquisition. Income tax for the third quarter 2022 was a tax benefit of 2.2 million as compared to income tax expense of 7.4 million for the…

Thank you. [Operator Instructions] Our first question will come from David Amsellem of Piper Sandler. Your line is open.

Hey, thanks. So, just had a few first on Qelbree. Can you just talk about the gross to net in 3Q? Looks like it was stable or trended down a little bit. So, talk about those dynamics and are you still sticking to your aspirational target of 50% to 55% over time? And then related to that, talk about your [payer/PBM] [ph] contract negotiations and where things may stand there? So, that's number one. Number two is, on Trokendi, might be a little bit early to talk about this, but can you give us some of your latest thoughts on what you think the erosion might look like or as differently how you are thinking about generic market formation and overall erosion of volumes and sales next year? That would be helpful as well. Thank you.

Yes, sure. Regarding the first question on Qelbree, the gross-to-net in Q3 is fairly stable, a little bit better than Q2, but that's a quarter-to-quarter type of fluctuation. So, yes, it did trend down. It's more in the 60% in the third quarter. The target absolutely is still in the 50% to 55%. That would be great. We're working pretty hard to get to that target as soon as we can within reasonable contracting parameters if we can achieve those. So, we will continue to have discussions with the various PBMs on hopefully reaching something that could be reasonable that will also help us on the gross to net eventually. As far as Trokendi XR and the erosion, we are, I mean, planning at this point, obviously, we're getting very close to next year and we'll talk more about it hopefully in February, but we're going to plan at this point and we ask people to look for as we said earlier erosion, probably around 90% erosion by December. So, over the 12 months, kind of 90% erosion by the end of 2023. It might be a little bit slower in the first quarter and then it will later dip quicker, the timing is really difficult to predict on whether you have a second generic and on how many SKUs out of the four different SKUs or product strengths that we have. So, it looks like there will be a first generic that will come in January 1 as the settlements allow on three product strengths, but there is still a very open question on 180 exclusivity on these three product strength as well, open question on the 180-day exclusivity on the fourth product strength. There is a second generic who has approval on all four product strengths. So, depending on the 180-day exclusivity status of these product strengths, it will determine then the timing of the entry of the second generic. So, all that is still at this point not 100% clear or certain, but that's where we are at this point and that's the latest information we have on that.

Okay. That's helpful. Thanks.

Sure.

Thank you. [Operator Instructions] One moment please for our next question. The next question will come from Annabel Samimy of Stifel. Your line is open.

Hi. This is Jack calling in for Annabel. Thanks for taking our questions. Two from us. So, first on Qelbree, we've seen a pretty meaningful uptick in prescription since the adult launch. Is this early penetration, primarily from a growing desire for non-stimulant options or more due to either a rebound from the back-to-school season or a lack of availability from Adderrall, given manufacturing delays? Just wanted to know if you think this is a sustainable trend or one that you could see reversal of when stimulant supplies return? And secondly on GOCOVRI, I know you've mentioned previously that your intentions with the effective re-launch or to essentially rework the narrative and focus on dyskinesia first and [off episodes] [ph] second to better differentiate it from competitors, do you have any early indications on how receptive physicians have been to this new strategy? And if they've begun to more meaningfully understand the advantages of the dual profile? Thanks.

Yes. Regarding the first question on Qelbree and the uptick, in the prescriptions. Certainly, we had two dynamics on top of each other working together in growing Qelbree and accelerating its growth in third quarter. As you well pointed out, first the adult launch, which we launched at the end of May, but then as the summer season, dwindled down so to speak and back to school season start coming up, you had the back to school effect on the pediatric. As I mentioned in the remarks, as far as the adult growth was around 77% growth in the third quarter, which was fairly the first full quarter right after the launch, and we continue to see adult growing. So, that is still growing. And then at the same time, we didn't see pediatric slowing down. So, pediatric continues to grow in the third quarter because of the back to school season. So, we're pretty pleased right now with both patient populations continue to show solid growth in both sides of the business. As I mentioned, 23% of our prescriptions per the weekly data that we get, which breaks it down by age is showing that about 23% is in adult. So, we have a long way to go as far as growth potential because if you remember the market is split up 67% adult and the remainder of pediatrics. So, we have a lot of potential out there that we can tap into. And what really keeps us positive about all this is certainly at the end of the day is the feedback we get from physicians about the performance of the product. So, consistent with what we've seen now for almost a year and a half, almost soon will be two years in the pediatric side. We're seeing…

Great. Thank you.

Thank you. [Operator Instructions] And I am seeing no further questions in the queue. I would now like to turn the conference back to Jack Khattar for closing remarks.

Thank you. In concluding our call this afternoon, I would like to emphasize that Qelbree’s and GOCOVRI's growth are our top priority. We're excited about Qelbree’s momentum, as well as GOCOVRI's performance and continued growth since the completion of the Adamas acquisition. We look forward to building on the momentum and finishing the year strong. I would like to thank all our employees for delivering a solid quarter with record revenues for Supernus and look forward to updating everyone on our next call.

This concludes today's conference call. Thank you all for participating. You may now disconnect and have a pleasant day.
