Thanks, Christian, and good morning and good afternoon to everyone. Overall, I'm pleased to report another good quarter of execution and business momentum. We delivered very strong top line growth driven by SUBLOCADE, and we grew our adjusted operating income versus the prior year, despite absorbing a full quarter's worth of Opiant expenses. I'll now provide some more detail on the performance drivers in the quarter. Starting with top line, total net revenue of $276 million reflected growth of 25% versus a year ago quarter, both on a reported basis and at constant exchange rates. By geography total U.S. net revenue grew by 26% versus the prior year quarter, while the rest of the world was up 19% year-over-year and 20% excluding FX. The rest of the world is benefiting from the launch of SUBLOCADE and SUBOXONE Film in new markets, as Mark discussed, as well as strong performance in more established markets, particularly Canada. SUBLOCADE net revenue outside of the U.S. grew 67% year-over-year to $10 million in the quarter. Total SUBLOCADE net revenue of $155 million for the second quarter of 2023 was stronger than what we had expected. Sequential net revenue growth for SUBLOCADE was 17%. I would note that based on the timing of the July 4th U.S. holiday, the restocking in the low single digits late in the quarter that we expect to gradually unwind in Q3. U.S. dispensers were up 16% sequentially in the quarter and aligned with net revenue adjusting for the stocking impact. Moving to PERSERIS, net revenue of $11 million was up 57% versus the prior year. Sequential growth of 38% was positively impacted by the destocking we highlighted in the first quarter of 2023. We continue to be encouraged by the performance we are seeing in PERSERIS on a number of internal metrics and are confident of reach our net revenue guide of $45 million to $55 million for the full year. Turning to SUBOXONE Film, the average share of approximately 19% in the second quarter was flat compared with both the first quarter and the year ago quarter. I'll come back to the outlook for this product in a moment with my guidance discussion, but as a reminder, we do not promote SUBOXONE Film in the U.S. Moving down the P&L, our second quarter adjusted gross margin of 83% was similar to the prior year quarter, mainly reflecting improved product mix offset by inflationary impact. Adjusted SG&A expenses were $125 million in the quarter, an increase of 17% versus Q2 of last year, reflecting the full quarter of added Opiant expenses, together with increased legal cost and inflationary impacts. R&D expenses were $32 million in the quarter. The expected increase in R&D was primarily driven by the progression of SUBLOCADE studies and pipeline assets, as well as activities relating to our additional contract manufacturing site. As Mark mentioned, we expect startup of this site in second half of 2023 and are pleased with this extra supply and risk mitigation initiative. Our strong net revenue performance helped to absorb the Opiant and OPVEE pre-launch expenses that were added when we closed the transaction in early March. As a result, adjusted operating income of $71 million in the second quarter was up 18% versus the prior year's $16 million. You should note that we continue to expect Opiant transaction to be accretive to earnings after the second full year of the OPVEE launch. Lastly, on the P&L, our adjusted net income of $56 million grew 24% in the second quarter versus last year, reflecting the dynamics I just highlighted. Quickly touching on the balance sheet and our capital position, we ended the second quarter with gross cash and investments of $782 million. During the first half, positive operating earnings were all offset by litigation related payments including the anti-trust MDL settlement of $102.5 million in June. Lastly, taking a closer look at guidance, we are increasing total company full year 2023 net revenue guidance to $1,030 million to $1,090 million from $970 million to $140 million, primarily due to the strong performance of SUBLOCADE in the first half of 2023. For SUBLOCADE, based on current performance trends, we are raising the full year 2023 net revenue guidance to a range of $590 million to 630 million, which represents a growth rate of 50% at the midpoint compared to full year 2022. With our gross margin and OpEx expectations unchanged with the Opiant expenses added in the last guidance revision in Q1 2023, we now expect adjusted operating income to be higher than last year's performance of $212 million. For film our guidance now assumes commercial availability of a fourth film generic in the U.S. at the start of the fourth quarter, whereas our previous guidance assumed this entry more in the mid 2023 timeframe. As we have stated previously, we have no specific market intelligence as to exactly when, or even if, this generic will launch. In the event that the additional generic does not launch by the start of the fourth quarter, we may choose to reinvest some of the net revenue upside in tactical commercial initiatives to accelerate the uptake and adoption of SUBLOCADE. Let me close by saying we are pleased with our execution and our financial results for the quarter. We believe our first half performance puts us subtly on track to deliver strong results in 2023. Importantly, we are confident that we can deliver our increased full year guidance. I will now turn the call back over to Mark.
