    Liisa Bayko's questions to Altimmune Inc (ALT) leadership • Q1 2025

    Question

    Liisa Bayko of Evercore ISI asked about patient discontinuation rates in the IMPACT study, the importance and expected benchmark for weight loss, and potential Phase 3 trial design elements like dose and endpoint timing.

    Answer

    CBO Ray Jordt expressed satisfaction with the trial's discontinuation rates and highlighted that weight loss is a key differentiator, benchmarking it against semaglutide's results adjusted for a 24-week timeline. CEO Dr. Vipin Garg confirmed they are strongly considering using the higher 2.4mg dose in Phase 3 to maximize weight loss and are also considering a 6-month endpoint to potentially accelerate the development timeline, pending FDA discussions.

    Liisa Bayko's questions to Altimmune Inc (ALT) leadership • Q4 2024

    Question

    Liisa Bayko of Evercore ISI asked about the strategy for prioritizing and funding pivotal NASH studies alongside new indications, the competitive positioning against survodutide and retatrutide, and for an update on the oral formulation of pemvidutide.

    Answer

    CEO Dr. Vipin Garg stated that the focus remains on the NASH Phase III program, with the new indications being relatively inexpensive options. CMO Dr. Scott Harris differentiated pemvidutide from competitors by highlighting its superior glucagon activity, liver defatting, and tolerability profile, noting the FDA did not require a cardiovascular safety trial. CBO Raymond Jordt mentioned progress on the oral formulation, stating they are nearing a commercially viable bioavailability.

    Liisa Bayko's questions to Altimmune Inc (ALT) leadership • Q3 2024

    Question

    Liisa Bayko of Evercore ISI questioned whether the FDA views cardiac safety issues as a class effect for GLP-1/glucagon agonists, given competitor data, and asked about the timing of initiating trials for the new indications relative to the MASH data readout.

    Answer

    CMO Dr. Scott Harris firmly stated that cardiac issues are not a class effect, noting pemvidutide has shown no such signals across its trials and that the FDA agreed with this assessment, concluding the issue is likely compound-specific to survodutide. He confirmed the first new indication trial will launch in H1 2025, with the exact timing relative to the MASH readout to be determined. CEO Dr. Vipin Garg reinforced that no additional safety studies are required for pemvidutide.

    Liisa Bayko's questions to Insmed Inc (INSM) leadership • Q4 2024

    Question

    Liisa Bayko asked if reauthorization for brensocatib treatment would likely require patients to meet certain markers of drug response.

    Answer

    CEO Will Lewis explained that the company's market access strategy is designed to prevent such requirements. By engaging in minor discounting and contracting, Insmed aims to establish a reauthorization process based on a physician's verbal attestation rather than specific clinical markers. He expressed confidence in this approach due to brensocatib's position as a first-in-disease, novel mechanism therapy.

    Liisa Bayko's questions to Insmed Inc (INSM) leadership • Q3 2024

    Question

    An analyst on behalf of Liisa Bayko of Evercore ISI questioned the flat sequential revenue growth for ARIKAYCE in Japan and its future outlook. They also asked about the likelihood of the FDA granting accelerated approval for ARIKAYCE's label expansion, given that Japan did not find the ARISE data sufficient.

    Answer

    CEO Will Lewis characterized the chance of accelerated approval based on ARISE data as a "long shot" with a low probability (less than 25%), though it remains a prudent discussion to have with the FDA. CFO Sara Bonstein addressed the Japan performance, explaining that flat sequential revenue was due to working down favorable inventory from Q2, while underlying fundamentals remain strong with over 30% year-over-year growth.

    Question

    An analyst on for Liisa Bayko asked about the flat sequential revenue for ARIKAYCE in Japan and the rationale for seeking accelerated approval in the U.S. given Japan's rejection of the ARISE data.

    Answer

    CFO Sara Bonstein explained that Japan's Q3 revenue was impacted by inventory dynamics after a strong Q2, but year-over-year growth was over 30% and fundamentals remain strong. CEO Will Lewis characterized the U.S. accelerated approval attempt as a 'long shot' with a low probability (<25%), but a prudent step to take with the FDA, acknowledging the most likely path to label expansion remains the full ENCORE data.

    Liisa Bayko's questions to Ultragenyx Pharmaceutical Inc (RARE) leadership • Q1 2025

    Question

    Liisa Bayko sought greater clarity on the timing for the setrusumab data readout and asked whether a positive announcement would be made separately from the release of the actual data.

    Answer

    CEO Emil Kakkis explained that cleaning and locking the international Phase III database is a lengthy process, estimating it takes around 8 weeks before analysis. He emphasized that because the full database is being prepared for a potential BLA, the time to see top-line data will be much faster than after the first interim. He left open whether the top-line announcement and subsequent data release would be simultaneous.

    Liisa Bayko's questions to Vertex Pharmaceuticals Inc (VRTX) leadership • Q1 2025

    Question

    Liisa Bayko requested more granularity on JOURNAVX prescriptions, asking about the number of fully paying patients and the current and target gross-to-net figures. She also asked for more color on the 60,000-patient population for the type 1 diabetes product, [ZEMACELL].

    Answer

    CFO Charlie Wagner explained that it was too early to provide specific gross-to-net details for JOURNAVX, as it is heavily impacted by patient assistance programs during the initial launch. He expects it to normalize as payer coverage expands through 2025 and into 2026. CEO Reshma Kewalramani described the initial 60,000-patient T1D population as the most severe cases with brittle diabetes, with plans to expand to broader populations later.

    Question

    Liisa Bayko questioned the sustainability of the improved paid drug rate for ORLADEYO, asking if it could potentially reverse. She also asked for an update on the current number of patients on treatment and the size of the remaining patient pool in the U.S. that has not yet tried the therapy.

    Question

    Liisa Bayko of Evercore ISI asked for context on how the kilopascal reduction in F4 patients translates to changes in fibrosis stage (e.g., F4 to F3). She also inquired about Rezdiffra's positioning against a potential MASH-indicated semaglutide, particularly concerning the price differential.

    Answer

    CEO William Sibold positioned Rezdiffra as having a superior profile for MASH due to its liver-directed mechanism, ease of use, and tolerability, suggesting semaglutide would expand the market, benefiting Madrigal as the leader. Dr. Michael Charlton explained that a 25% reduction in liver stiffness is highly predictive of a one-stage or greater improvement in fibrosis.
