Thanks Martine and good morning, everyone. As Martine noted, today, we reported yet another quarter of record revenue at $715 million and 20% growth from the second quarter of 2023. We saw meaningful worldwide revenue growth for all of our key products, Tyvaso, Orenitram, Remodulin, and Unituxin. First, I want to touch on Tyvaso, which when viewing the nebulizer and dry powder inhaler delivery systems together, remains the number one prescribed prostacyclin treatment in the U.S. Total Tyvaso revenue for the second quarter was $398 million, up 25% over last year with growth led by continued uptake of Tyvaso DPI, increase in pricing, and increased commercial utilization, following the implementation of the Part D redesign provisions under the Inflation Reduction Act, or IRA. For the franchise, we saw record referrals and starts during the quarter, leading us to have confidence in the durability of our growth profile, as Martine mentioned. The percentage of Tyvaso DPI patients using our patient access programs continues to tick down following the implementation of the first provisions of the IRA earlier this year, albeit not at the same rate we saw between the fourth quarter of 2023 and the first quarter of 2024. We could continue to see a modest decline in patient access program utilization through the remainder of the year as new patients on therapy are less likely to need patient assistance, having met their copay obligations on another product before starting Tyvaso DPI. The benefit from this could be offset by modest rebates from our initial contracting efforts to ensure a period of access in the future for Tyvaso DPI. As an aside, we understand that CMS will soon publish the negotiated prices for the first 10 drugs selected under the IRA's drug price negotiation provision. I want to remind investors that our drugs are not on this list. In addition, based on our current understanding of the IRA statute and guidance issued by CMS thus far, we expect our treprostinil products will not be subject to price negotiation under the IRA because there is at least one marketed generic version of treprostinil. Moving to Orenitram. We reported getting another quarter of record revenue at $107 million, representing 13% growth from the second quarter of 2023. Like the first quarter, this was driven by a combination of increased commercial utilization, pricing, and a modest increase in average dose from prior quarter levels. Recall that Orenitram and Remodulin are priced on a per milligram basis. Like with Tyvaso DPI, we saw a modest decrease in patient access program used for Orenitram in the second quarter, driven by the same dynamics. Likewise, we expect a modest decline in patient access program used through the remainder of the year. Our medical teams continue to have scientific discussions based on recent scientific publications, with healthcare providers on the EXPEDITE induction protocol where PAH patients initiate on Remodulin and then transition to Orenitram as an option for appropriate patients who may not want or need to go on long-term parenteral therapy. Moving to Remodulin. Worldwide revenue of $147 million was up 16% from last year with very strong performance across all of our underlying demand metrics. And this comes five years after the first launch of generic Remodulin, reflecting our continued commitment to our patients and Remodulin. Remodulin, both intravenous and subcutaneous remains the most prescribed parental prostacyclin in the US. Our Remunity pump remains the only option for new subcutaneous patient starts. Last quarter, we heard through the channel that specialty pharmacy distributors are going to start proactively converting all subcu treprostinil use, to Remodulin and our immunity pump given the discontinuation of support for the CAD MS3 system by its manufacturer. We've seen this trend continue through the second quarter. Finally, Unituxin. Worldwide revenue of $52 million was up 17% from the prior year quarter and US Unituxin revenue of $47 million was up 18%. US growth was driven by price and volume. To wrap-up with our fifth quarter in a row of record revenue, our commercial products clearly have the innovation, interest momentum and muscle to continue to grow serve our patients. With that, I'll turn the call back over to Martine to run the Q&A.
