    Huidong Wang's questions to Intellia Therapeutics Inc (NTLA) leadership • Q1 2025

    Question

    Huidong Wang inquired about the MAGNITUDE Phase III trial's enrollment progress and the baseline characteristics of patients, specifically the percentage on baseline stabilizers and the rate of patients dropping off to use silencers.

    Answer

    Chief Medical Officer David Lebwohl confirmed that enrollment is progressing well and that the company expects over 50% of patients to be on baseline tafamidis, which is valuable for demonstrating added benefit. He noted that while no patients have crossed over to a silencer therapy yet, the trial's statistical plan accounts for this possibility.

    Huidong Wang's questions to Intellia Therapeutics Inc (NTLA) leadership • Q4 2024

    Question

    Huidong 'Gena' Wang questioned the confidence behind the projection of enrolling 550 patients in the ATTR cardiomyopathy trial by year-end and whether that implies full enrollment in the first half of 2026.

    Answer

    CEO John Leonard expressed high confidence, citing the company's track record of under-promising and over-delivering. He stated that enrolling 550 patients by year-end is a 'very highly likely outcome' based on robust current enrollment rates and that the study is expected to complete enrollment well within the 2027 timeframe.

    Huidong Wang's questions to Vertex Pharmaceuticals Inc (VRTX) leadership • Q1 2025

    Question

    Huidong (Gena) Wang asked for more color on the tolerability issue that led to the temporary pause of the VX-522 study. She also inquired how the ALYFTREK launch trajectory compares to previous CFTR modulator launches and if the trend is expected to pick up.

    Answer

    CEO Reshma Kewalramani declined to provide more detail on the VX-522 pause to maintain study integrity, reiterating that the team is assessing a tolerability issue. COO Stuart Arbuckle explained that comparing ALYFTREK's launch to ORKAMBI or TRIKAFTA is difficult because those drugs opened up treatment to tens of thousands of new patients, whereas ALYFTREK's new patient population is smaller. He affirmed the company is pleased with the launch to date.

    Huidong Wang's questions to BioCryst Pharmaceuticals Inc (BCRX) leadership • Q1 2025

    Question

    Huidong Wang asked for a detailed walkthrough of the process that enabled the significant and rapid improvement in the ORLADEYO paid rate. She also inquired about the specific benchmark for retinal edema reduction in the DME trial that would be considered encouraging enough to advance the program.

    Answer

    CEO Jon Stonehouse described the paid rate improvement as a 'snapback.' Chief Commercial Officer Charlie Gayer elaborated that it was driven by the IRA resolving Medicare affordability issues and the team's use of long-term real-world data to convince commercial payers. For the DME program, Chief R&D Officer Dr. Helen Thackray stated they are looking for a 'clear and uncontroversial reduction in edema' rather than a specific micron number, which would signal that the dose is effective. If not, the dose will be increased.

    Huidong Wang's questions to BioCryst Pharmaceuticals Inc (BCRX) leadership • Q4 2024

    Question

    Huidong Wang, on behalf of Gena Wang, asked for the percentage of ORLADEYO patients covered by Medicare and the expected trend in their paid status. She also requested details on the Netherton syndrome trial design, including dose escalation and the KLK5 activity benchmark for advancing to patients.

    Answer

    Chief Commercial Officer Charlie Gayer stated that Medicare patients constitute about 20% of the total patient base and their paid rate was around 55-56% at year-end, a figure that is now improving. Chief R&D Officer Dr. Helen Thackray explained the Phase 1 trial design involves dose escalation in healthy volunteers to establish safety before moving to patients to assess KLK5 activity, with the goal of achieving nearly complete suppression of the target.

    Huidong Wang's questions to BioCryst Pharmaceuticals Inc (BCRX) leadership • Q3 2024

    Question

    Huidong Wang asked what actions BioCryst could take if the Medicare paid rate situation becomes unfavorable and requested details on the upcoming Phase 1 data for BCX-17725, including the use of biopsies and specific biomarkers.

    Answer

    CEO Jon Stonehouse stated the Medicare trend is positive, with the paid rate already improving to 55%, and the only uncertainty is the speed of further improvement. Chief R&D Officer Dr. Helen Thackray confirmed that skin biopsies are a critical first step for BCX-17725 to demonstrate drug penetration and target binding. Key biomarkers will assess KLK5 inhibition and potentially downstream cytokines, with the drug's potency possibly allowing for extended dosing intervals.

    Question

    Huidong (Gena) Wang asked for guidance on a comparable benchmark for AMVUTTRA's first full quarter revenue in cardiomyopathy, referencing competitor launches. She also sought to confirm if any of the Q1 TTR franchise revenue growth was attributable to the new indication.

    Question

    Huidong Wang questioned if the low Q1 U.S. COVID revenue signaled a future market share loss and asked for the number of events planned for the flu vaccine's interim analysis.

    Answer

    CFO Jamey Mock attributed the low Q1 revenue to customer inventory management rather than market share loss, pointing to script data showing a stable 38% share. President Stephen Hoge declined to provide a specific number of events for the flu analysis but confirmed it was a large number due to an intense flu season.

President Stephen Hoge explained that a priority review voucher for the combo vaccine was not used because it would not accelerate approval in time for the 2025 contracting season.
