Answer

Howard Horn, Chief Financial Officer, stated that the financing, combined with continued double-digit revenue growth, managed expenses, and planned PRV monetizations (UX111, DTX401, UX143), supports the path to profitability in 2027. Erik Harris, Chief Commercial Officer, expressed confidence in both Orbit and Cosmic succeeding, but noted that even if one missed, the safety and bone density data would likely support a broad label, and adoption would be driven by the overall clinical picture.

Tazeen Ahmad from Bank of America questioned whether the magnitude of clinical benefit in the ORBIT trial's final 18-month readout would be more critical than just statistical significance, given the time taken to show separation from the control group.

Answer

Emil Kakkis, Founder, President & CEO, responded that the treatment effect size could be consistent, with variation merely extending the time to statistical separation. He argued that any fracture reduction in the 40-60% range is a substantial benefit. He emphasized that, similar to Crysvita, the key driver for adoption will be the drug's impact on functional ability and overall patient health, not just the primary endpoint percentage.

Tazeen Ahmad asked about the osteogenesis imperfecta (OI) study, questioning the likelihood of success and potential reasons for concern if the trial proceeds to its final analysis instead of stopping at the second interim.

Answer

CEO and President Emil Kakkis clarified that the next step after the second interim is the final analysis, not a third interim. He expressed high confidence that the study would succeed at one of these two points, noting the final analysis has a much easier p-value threshold of 0.04. He identified patient variability as the main risk in rare disease trials but stated that the study's large size (159 patients) and the drug's profound effect on bone mineral density provide a strong basis for success.

Tazeen Ahmad inquired about Ultragenyx's confidence in the second interim analysis of the Orbit study for osteogenesis imperfecta (OI) being sufficient to stop the trial early.

Answer

CEO Emil Kakkis expressed high confidence that the trial will succeed this year, either at the second interim analysis or the final readout. He noted the second interim has a greater chance of success than the first due to a stringent 0.01 p-value threshold and patients having at least 12 months of treatment, allowing for better separation between study groups.

Tazeen Ahmad asked about the setrusumab trial for Osteogenesis Imperfecta (OI), questioning if missing the first interim analysis would impact the overall likelihood of success and how the commercialization timeline would be affected by the different potential stopping points.

Answer

CEO Emil Kakkis clarified that missing the first interim analysis would not affect the ultimate efficacy determination, as it relates to the speed of event separation, not the drug's power. He emphasized that shortening the timeline by even a few months through an interim success has a substantial positive impact on the program's net present value (NPV), justifying the aggressive approach.

Regarding CRENESSITY, he explained that uptake is trending towards more pediatric and adolescent patients than adults, which aligns with the company's pre-launch expectations.

Tazeen Ahmad asked for expectations on INGREZZA's Q1 2025 performance, considering typical seasonality and a potential for lower revenue per script, and whether a quarter-over-quarter revenue decline is possible.

Answer

Chief Commercial Officer Eric Benevich acknowledged that Q1 is typically challenging due to prescription reauthorizations and gross-to-net pressures. Chief Financial Officer Matthew Abernethy clarified that while full-year 2025 net revenue per script is expected to be similar to 2024, there is a sequential gross-to-net headwind of about 3% from Q4 into Q1. He also noted potential for ordering pattern noise due to the calendar setup.

Tazeen Ahmad of Bank of America asked for color on INGREZZA's sequential growth expectations for Q4, noting that the updated guidance seems to imply a flattish quarter.

Answer

CFO Matt Abernethy clarified that the guidance implies sequential growth of $10 million to $20 million, which is consistent with historical Q4 trends. He attributed the moderation to the time it takes for the new sales force expansion to become fully productive and a typical sequential increase in the gross-to-net discount in the fourth quarter.

Tazeen Ahmad posed commercial questions regarding Vepdeq, asking how the launch preparation and salesforce plans have changed, and whether there could be a gap between potential FDA approval and launch if Pfizer returns the rights and a new partner must be found.

Answer

CEO John Houston explained that the original 50/50 co-commercialization deal with Pfizer is no longer sensible for a second-line monotherapy indication alone. Arvinas is not building out a salesforce and is in active negotiations with Pfizer to either revise the deal for Pfizer to lead the launch or for Arvinas to regain the asset. If the asset is returned, Arvinas would immediately seek a new partner to commercialize it, aiming to avoid any gap between approval and launch.

Tazeen Ahmad asked about the market opportunity for vepdegestrant versus Orserdu, details on remaining Pfizer milestones, including any for the KAT6 collaboration, and whether Arvinas still plans to explore vepdegestrant in first-line metastatic breast cancer.

Answer

CEO John Houston highlighted a significant opportunity, noting a targeted launch to ~6,000 oncologists could be highly effective. CFO Andrew Saik confirmed a milestone is due on first approval but not its amount, and none are specific to the KAT6 combo. Houston reiterated that the first-line trial is not proceeding at this time, with funds being reallocated to other pipeline assets.

Tazeen Ahmad asked what data would be needed to build confidence among Key Opinion Leaders for atirmociclib, given their familiarity with other CDK inhibitors. She also inquired about the differentiation of Arvinas's KRAS G12D degrader in a competitive field.

Answer

Chief Medical Officer Noah Berkowitz suggested that an improvement in median PFS of over 5-6 months would be needed to be viewed as a substantial advance. Chief Scientific Officer Angela Cacace highlighted that their KRAS degrader is significantly more potent than competitors, binds both active and inactive KRAS states, and has a distinct mechanism that could overcome resistance, a point reinforced by Dr. Berkowitz who noted potency could be key to avoiding toxicity issues seen with other agents.

Tazeen Ahmad of Bank of America inquired about the ARV-102 program, asking about the size of the Parkinson's disease population with elevated LRRK2 and how biomarkers will be used for patient segmentation.

Answer

CSO Angela Cacace estimated that about one-third of idiopathic Parkinson's patients have elevated LRRK2 and noted a partnership with the Michael J. Fox Foundation to understand how to use biomarkers for stratification. CMO Noah Berkowitz added that the current healthy volunteer study is in all-comers, and the data will inform the patient selection strategy for future trials.

Tazeen Ahmad of Bank of America asked for clarification on the upcoming Prader-Willi syndrome data, questioning if it's an exploratory or high-conviction study, what would be considered 'good data', and the number of patients expected in the readout.

Answer

David Meeker, Chairman, President & CEO, described the study as exploratory with a 'legitimate fifty-fifty' chance of success. He explained that while there is high conviction in the MC4R pathway's role, the disease is challenging. He noted the goal is to report on 10 to 20 patients by the end of the year to have a meaningful basis for assessment.

Tazeen Ahmad of Bank of America questioned the necessity of continual data updates at conferences given the strength of existing data and asked about expectations for revenue seasonality for the rest of the year.

Answer

David Meeker, Chairman, CEO, and President, explained that early in a launch, every incremental patient data point, like the upcoming 24-patient French HO data, is valuable for building confidence. Jennifer Chien, Head of North America, noted that Q1 sees the biggest seasonal impact from insurance changes, and while Q4 can have some specialty pharmacy ordering variability, significant seasonality is not expected in other quarters.

Tazeen Ahmad asked what level of weight loss physicians want to see in HO patients for immediate adoption and whether the company would consider another capital raise following the HO data readout.

Answer

CEO David Meeker responded that physicians are focused on having an effective therapy where none exists, not a specific weight loss percentage. CFO Hunter Smith added that the recent ATM provides flexibility, so they do not have to raise post-data, but they haven't ruled out future raises to fund pipeline success.

Tazeen Ahmad asked if the H1 2025 guidance for the Phase III hypothalamic obesity (HO) data readout could be narrowed and inquired about physician interest in combining setmelanotide with GLP-1s.

Answer

Chairman, CEO and President David Meeker explained that the H1 2025 timeline is based on the last patient's 60-week follow-up and subsequent data cleanup, making it difficult to refine the guidance further publicly. He confirmed there is physician interest in combination therapies, noting that adding a GLP-1 could provide incremental benefit for patients and that anything improving patient outcomes is a positive.

Tazeen Ahmad of Bank of America inquired if povetacicept (POVY) is planned to launch with an auto-injector for IgAN and asked for the rationale behind prioritizing generalized myasthenia gravis (gMG) in what appears to be a crowded market.

Answer

President and CEO Dr. Reshma Kewalramani confirmed the plan to launch POVY with an auto-injector. She justified prioritizing gMG due to high unmet need, POVY's mechanism targeting the underlying cause, promising class data, an efficient regulatory path, and the drug's best-in-class engineering.

Tazeen Ahmad inquired about the profile of early JOURNAVX patients and the specific treatment settings where scripts are being written. She also asked about the timing of revenue acceleration and whether it would begin in Q2 or be more back-end loaded in 2025.

Answer

CCO Duncan McKechnie stated that JOURNAVX is being used broadly across surgical and non-surgical settings (e.g., joint replacements, ankle sprains) by a wide range of physicians. He confirmed that the company has consistently guided that prescription volume would ramp in the first half of the year, with revenue accelerating in the second half as payer coverage is secured.

Tazeen Ahmad asked if Vertex anticipates cannibalization of TRIKAFTA by ALYFTREK this year and at what rate. She also inquired about expectations for the upcoming data from the Type 1 Diabetes program.

Answer

COO Stuart Arbuckle confirmed that Vertex expects patients to switch from TRIKAFTA to ALYFTREK due to its favorable profile but did not provide guidance on the rate of switching. CEO Reshma Kewalramani detailed the Type 1 Diabetes program, VX-880, noting the initial target population is about 60,000 patients and that the company aims to complete enrollment in the pivotal study this year.

Tazeen Ahmad from Bank of America asked if the upcoming lumbosacral radiculopathy (LSR) data for suzetrigine would have a read-through to other indications and sought commentary on a competitor's discontinuation of a NaV1.8 inhibitor due to a narrow therapeutic window.

Answer

CEO Dr. Reshma Kewalramani stated there is no read-through from LSR to the DPN program, which is already in Phase III. Regarding the competitor, she was not surprised, explaining that achieving high specificity for NaV1.8 is a major challenge that Vertex has overcome with its molecule.

Tazeen Ahmad of Bank of America asked about Orlodeyo's current market penetration, the source of new prescriptions (new vs. existing prescribers), and the expected 'stickiness' of patients with potential new oral competitors on the horizon.

Answer

President & CCO Charlie Gayer stated that with approximately 11,000 diagnosed patients, there is still significant room for growth. He noted a strong influx of 69 new prescribers in Q2. Both Gayer and CEO Jon Stonehouse asserted that patients who do well on Orlodeyo are 'extremely sticky' and unlikely to switch, as they do not see a superior profile among potential future oral therapies compared to the convenience and efficacy of once-daily Orlodeyo.

Tazeen Ahmad inquired about the expected timing for patient data from the Netherton syndrome program, what would constitute a positive outcome, and the potential regulatory path forward for BCX17725.

Answer

Chief R&D Officer Dr. Helen Thackray stated that initial patient data is expected this year, noting that even a small number of patients could validate the mechanism. Positive data would involve suppressing KLK5 activity and observing subsequent skin healing. She suggested the regulatory path could be a single, short pivotal trial. CEO Jon Stonehouse added that the ultimate goal is a "functional cure," and a larger treatment effect could accelerate the development timeline.

Tazeen Ahmad inquired about the specific data investors should expect from the Netherton syndrome program in 2025 and asked for directional guidance on operating expenses for the upcoming year.

Answer

Chief R&D Officer Dr. Helen Thackray outlined a progressive data release for the Netherton program, starting with skin penetration, followed by markers of activity, and then longer-term skin recovery. CEO Jon Stonehouse emphasized the goal is a 'functional cure.' CFO Anthony Doyle indicated that while OpEx will increase in 2025 to support clinical trials, revenue growth will significantly outpace this spending, leading to continued margin accretion.

Tazeen Ahmad from Bank of America inquired about the clinical read-through from the CALR (989) data in essential thrombocythemia (ET) to myelofibrosis (MF) and asked about the minimum activity threshold for monotherapy.

Answer

President and Head of R&D Pablo Cagnoni explained that the drug's mechanism is identical in both diseases, increasing the probability of success in MF. He noted the data release was shifted to later in the year to include combination data with ruxolitinib. For MF, he stated they expect to see improvements in spleen volume, symptoms, and potentially hemoglobin.

Tazeen Ahmad inquired about the data timeline and expected level of detail for Incyte's monoclonal antibody pipeline asset, Klar, anticipated in 2025.

Answer

Pablo Cagnoni, an executive at Incyte, confirmed that a substantive data update for the monoclonal antibody will be presented in 2025. The update will include dose escalation data, results in both ET and myelofibrosis, and information on clinical endpoints and variant allele fraction burden.

Tazeen Ahmad from Bank of America asked for details on how Incyte formulated its 2025 guidance for Opzelura, particularly regarding assumptions on tube usage for atopic dermatitis and vitiligo. She also asked what would be considered clinically meaningful data for povorcitinib in hidradenitis suppurativa (HS), beyond just statistical significance.

Answer

Christiana Stamoulis, CFO, explained that the Opzelura guidance of $630M-$670M reflects 24-32% growth driven by demand in AD/vitiligo, the pediatric AD launch, and EU contribution, with the range accounting for variables in patient adherence. Pablo Cagnoni, President, Head of R&D, added that for povorcitinib, a competitive profile would involve replicating the overall Phase II results, including strong effects on HiSCR levels and pain, coupled with a clean safety profile.

Tazeen Ahmad of Bank of America Corporation asked for clarification on how the hidradenitis suppurativa (HS) opportunity would differ for ruxolitinib cream versus povorcitinib, and inquired about the expected tube usage for the cream in HS.

Answer

Steven Stein, an executive, differentiated the two by patient population: ruxolitinib cream targets the mild-to-moderate HS population (100k-150k patients) with limited abscesses and no draining tunnels, while oral povorcitinib targets the moderate-to-severe population with more extensive disease. He noted that determining tube usage and treatment duration would require data from the Phase III studies but anticipated it would likely be long-term therapy.

Tazeen Ahmad questioned how Apellis calculates its new patient share for SYFOVRE compared to its competitor and asked for the rationale behind not issuing sales guidance when its competitor has.

Answer

Executive David Acheson stated that Apellis uses a highly accurate site-of-care dataset covering 50% of the market, contrasting it with less accurate claims data. Executive Timothy Sullivan explained that the company is holding off on guidance due to recent market dynamics, including a competitor's CRL and co-pay funding issues, as well as the upcoming EMPAVELI launch. Executive Caroline Baumal added that GA market adoption will likely be a steady growth process, similar to the early wet AMD market.

Tazeen Ahmad from Bank of America Securities asked for the Q1 SYFOVRE sales outlook, the potential impact of Medicare Advantage preferred status, and the significance of the competitor's updated label.

Answer

EVP of Commercial David Acheson stated that Q1 net revenue is expected to be lower than Q4 due to temporary factors like sample usage, but noted that underlying injection demand is growing. Regarding the competitor's label, Mr. Acheson and CMO Dr. Caroline Baumal highlighted SYFOVRE's differentiated profile, including its proven efficacy with every-other-month dosing, as a key competitive advantage.

Tazeen Ahmad from Bank of America asked when Apellis might provide formal sales guidance for SYFOVRE and how the company views the growth rate and ultimate size of the geographic atrophy (GA) market.

Answer

CFO Timothy Sullivan responded that providing 2025 guidance is currently under consideration. He explained that the company wants to first observe the impact of its new commercial initiatives and allow market dynamics to settle before committing to a formal sales forecast. The immediate focus remains on solidifying SYFOVRE's market leadership.

Tazeen Ahmad asked which of the three headwinds—site capacity, administrative delays, or the patient death—was the biggest driver of the revised guidance, and whether the situation has worsened in Q2 2025.

Answer

President and CEO Douglas Ingram responded that it was a mix of all three factors, with longer cycle times having the largest mechanical effect on the forecast. He clarified the situation is not worsening and that the company is assuming a steady state for planning purposes, though this may be conservative. He noted the Q2 softness was expected as delays from the late Q1 safety event flowed into the new quarter, but "green shoots" like new start forms are appearing.

Tazeen Ahmad of Bank of America inquired about the patient onboarding cadence for ELEVIDYS in Q1 2025 and the expected trajectory of uptake for the remainder of the year.

Answer

CEO Douglas Ingram reiterated strong confidence in the full-year guidance of $2.9 billion to $3.1 billion, with over two-thirds from ELEVIDYS. He confirmed expectations for sequential quarter-over-quarter growth throughout 2025, attributing the ramp-up pace to the natural cadence of the patient journey, which includes administrative steps, contracts, and infusion scheduling.

Tazeen Ahmad of Bank of America sought clarification on Sarepta's Q4 guidance for ELEVIDYS, asking if the previously guided 100% upside for Q4 would be based on the original Q3 guidance or the newly reported, higher Q3 results.

Answer

President and CEO Doug Ingram confirmed that the company remains comfortable with its prior guidance, which was based on the original Q3 forecast. He also reiterated confidence in the 2025 guidance of approximately $3 billion in revenue and the long-term peak sales forecast of $5 billion or more across its four approved therapies.

Tazeen Ahmad asked for clarification on the primary bottleneck causing the 3-to-5-month patient journey for ELEVIDYS, questioning if this timeline has changed since the initial narrow approval.

Answer

CEO Douglas Ingram responded that there is no fundamental bottleneck, explaining that the 3-to-5-month timeline is a normal process for complex gene therapies, which includes antibody testing. He emphasized that demand, start forms, and payer interactions are all strong, and the company is performing brilliantly. He noted that Q3 will see moderate growth, with a significant ramp in Q4 and into 2025, consistent with prior successful Duchenne therapy launches.

Tazeen Ahmad of Bank of America Securities asked for clarification on the 'onetime' nature of the VPAG rebate, the positioning of Pombiliti/Opfolda in new markets, and if the DMX-200 deal signals a broader strategic move into nephrology.

Answer

President and CEO Bradley Campbell clarified the 'onetime' issue was the unexpectedly large size of the annual VPAG rebate, not the rebate itself. He stated Pombiliti/Opfolda's positioning is based on its strong data, leading to favorable reimbursement. Chief Business Officer Sebastien Martel added that while the deal expands their U.S. presence in rare kidney disease, their strategy remains focused on adjacencies like neuromuscular and rare cardiology.

Tazeen Ahmad questioned the status of the remaining litigants in the Galafold IP case, the potential for a better settlement outcome, and asked for an update on Galafold's patient dropout rates.

Answer

President and CEO Bradley Campbell confirmed two remaining litigants but expressed high confidence in the company's IP position, noting he would not expect a settlement date later than the January 2037 agreement with Teva. He also highlighted that Galafold's patient discontinuation rate has progressively decreased, contributing to sustained growth.

Tazeen Ahmad inquired about the launch cadence for Pombiliti and Opfolda, comparing the dynamics in Europe versus the U.S. given their different labels.

Answer

President and CEO Bradley Campbell explained that both markets are progressing well but have distinct dynamics. The U.S., as the largest single market, will see strong, consistent new patient growth. Europe's growth will be driven by the phased addition of new countries. Campbell noted that in Europe, they see switches from both Myozyme and Nexviazyme plus naive patients, while the U.S. launch primarily involves switches from existing therapies.

Inquired about the ease of identifying Mayo Stage IV patients, the expected ramp-up time for patient onboarding post-launch, and the potential for the drug's label to extend beyond Stage IV patients.

Answer

The quoted patient numbers are for diagnosed and treated patients, so they are not hard to find as they are already in the healthcare system. The company expects a gradual uptake as it will be their first launch, requiring time for contracting and physician education. The current focus is on Mayo Stage IV patients.

Tazeen Ahmad from Bank of America inquired about the commercial launch of birtamimab, including the ease of identifying the ~5,000 U.S. Mayo Stage IV patients, the expected onboarding timeline, and whether the label could extend beyond Stage IV patients.

Answer

COO Brandon Smith stated that since these patients are already diagnosed and treated, they are identifiable, though he acknowledged that building uptake for a first commercial launch will take time.

Tazeen Ahmad asked for a repeat explanation of the inventory dynamics for ZURZUVAE and how analysts should incorporate these factors into their models for 2025.

Answer

CEO Barry Greene and COO Chris Benecchi reiterated that patient shipments are the truest measure of demand, showing over 20% quarter-over-quarter growth. They explained that reported revenue is recognized upon shipment to wholesalers and can fluctuate based on inventory management at both wholesalers and specialty pharmacies. They advised focusing on the underlying demand trend rather than short-term inventory shifts.

Tazeen Ahmad asked about the breadth versus depth of Zurzuvae prescribing and sought more detail on the rationale for discontinuing the development of zuranolone for Major Depressive Disorder (MDD).

Answer

CEO Barry Greene explained the MDD decision was a matter of resource prioritization, given the significant time and investment new trials would require. Chief Business Officer Chris Benecchi added that for Zurzuvae, both prescriber breadth and depth are increasing quarter-over-quarter as physicians gain positive real-world experience with the drug.

Tazeen Ahmad asked for guidance on R&D expenses for the remainder of the year, considering the recent decrease and the planned Q4 sales force expansion.

Answer

CEO Barry Greene noted that the Q3 2023 restructuring successfully lowered both R&D and SG&A expenses. CFO Kimi Iguchi reaffirmed that overall operating expenses are expected to decrease in 2024 compared to 2023 and that the company's cash runway guidance remains unchanged, extending into 2026.

Asked about the efficacy bar for FT576 in multiple myeloma, the expected timing for FT522 data, and whether the company would confirm safety before the data release.

Answer

For FT576 to advance, its efficacy profile must be similar to T-cell engagers, with response rates over 60% and complete response rates around 40%. An initial clinical data update for FT522, which will include the no-conditioning arm, is expected in the second half of 2024. The company will provide updates on safety as the study progresses.
