Answer

Ludovic Helfgott (EVP - Product & Portfolio Strategy) noted stay time varies, with initiatives aimed at extending it by highlighting long-term benefits. For amicretin, Martin Lange (CSO) explained the Phase 2 data will help determine the optimal dose for diabetes, specifically whether it needs to be different from the obesity dose to balance glycemic control and weight loss.

Richard Vosser from JPMorgan Chase & Co. asked about the pricing outlook for Wegovy and Ozempic for the second half of 2025 and into 2026, and the potential impact of the SURPASS-CVOT trial results on competitive dynamics.

Answer

CFO Karsten Knudsen indicated Wegovy price erosion would be more skewed to H2 2025 due to channel mix and access investments. EVP Martin Lange noted that SURPASS-CVOT data showed non-inferiority to dulaglutide, reinforcing that semaglutide's 26% CV risk reduction remains unsurpassed in the incretin class. EVP Ludovic Helfgott added this validates that not all GLP-1s are the same.

Richard Vosser asked about the apparent conflict in partnering with telehealth companies that also offer compounded drugs and questioned the competitive landscape for Ozempic in International Operations (IO) against Mounjaro.

Answer

Dave Moore, EVP of U.S. Operations, clarified that Novo Nordisk does not support unlawful compounding and that telehealth partnerships are designed to provide patients access to authentic Wegovy. Maziar Doustdar, EVP of International Operations, stated that Novo Nordisk maintains a stable 64% volume market share for injectable GLP-1s in IO and is accelerating Wegovy launches as supply constraints ease.

Richard Vosser asked about the anticipated impact of the Medicare Part D redesign in 2025 on the net pricing for Ozempic and Rybelsus.

Answer

Karsten Knudsen, Group's CFO, indicated that the situation remains uncertain as formulary negotiations are ongoing. He noted that the company's view on the redesign's financial impact has shifted from positive to 'broadly neutral.' The final effect on Novo Nordisk will depend on how plan sponsors react, but he stated the underlying competitive dynamics are unchanged.

Richard Vosser of JPMorgan Chase & Co. questioned how the Inflation Reduction Act (IRA) and direct price negotiations could affect the long-term, mid-single-digit growth outlook for Cosentyx through 2029.

Answer

CEO Vasant Narasimhan confirmed that the potential impact of the IRA is already factored into the company's guidance. He noted that approximately 30% of Cosentyx sales are exposed to Medicare, an impact the company believes is manageable and consistent with its long-term forecast for the drug.

Richard Vosser questioned the dynamic for Scemblix, where strong prescription growth appeared to outpace revenue growth. He asked whether this was due to heavier rebating to gain first-line volume or if a revenue acceleration was expected later in the year.

Answer

CEO Vasant Narasimhan clarified that the discrepancy is likely an artifact of third-party data (IQVIA) versus the company's internal data. He stated that internal data shows TRx growth of 73%, which aligns closely with the 75% net sales growth. He attributed the difference to the product's specialty distribution channel and affirmed the focus is on accelerating first and second-line growth.

Richard Vosser noted that Kisqali's NBRx share in metastatic breast cancer has remained around 50% and asked what it would take to displace Ibrance further, questioning if the adjuvant launch provides a halo effect.

Answer

CEO Vasant Narasimhan acknowledged the share but highlighted that it began gaining last year after the positive early breast cancer (eBC) readout. He expressed hope that having a single medicine for both eBC and metastatic settings will help drive the NBRx share higher, toward a potential cap of 75-80%. However, he emphasized the main focus is maximizing the unique opportunity in node 0 and node 1 eBC patients.

Richard Vosser from JPMorgan Chase & Co. requested an update on the filing plans for pelabresib, asking what additional data is needed and what conversations are being held with regulators.

Answer

He mentioned that good discussions have occurred with both the FDA and EU regulators, and this upcoming data will clarify the specific requirements for filing in each region. He also noted the potential of the acquired EZH1/2 inhibitor to strengthen the prostate cancer portfolio.

Richard Vosser asked about the key learnings from the discontinued Novartis collaboration and whether the issue was with the DARPin technology or the targets themselves. He also requested clarification on what would constitute a good tumor-to-kidney ratio for MP0712.

Answer

CEO Patrick Amstutz explained the Novartis partnership ended due to a lack of strategic interest in the selected targets from both parties, not a failure of the DARPin technology. He noted the collaboration was a valuable learning experience in radiotherapeutics. Michael Stumpp, EVP of Projects, addressed the kidney ratio, stating that while a 2:1 ratio is ideal preclinically, the key clinical metric will be the overall therapeutic window in patients, rather than a single, specific number, due to tumor heterogeneity.

Inquired about the key learnings from the discontinued Novartis programs and what constitutes a good tumor-to-kidney ratio to look for in the upcoming MP0712 data.

Answer

The Novartis collaboration provided significant learnings on radiotherapeutic profiles and the need for rapid iteration, which wasn't possible within that collaboration's structure. The targets also failed to build scientific excitement. Regarding the tumor-to-kidney ratio for MP0712, the company aims for better than 2:1 preclinically but emphasized that in patients, the overall therapeutic window is more important than a single ratio, as it depends on many factors.

Richard Vosser asked about the key learnings from the discontinued Novartis programs and what would be considered a favorable tumor-to-kidney uptake ratio for MP0712 in the upcoming clinical studies.

Answer

CEO Patrick Amstutz explained that the Novartis collaboration provided crucial learnings on optimizing radiotherapeutics, particularly the need for rapid iteration of candidates to find the best tumor-to-kidney ratio. He clarified the partnership ended due to a mutual lack of strategic interest in the specific targets, not a technological failure. Michael Stumpp, EVP of Projects, noted that while a preclinical tumor-to-kidney ratio above 1 (ideally 2:1) is targeted, the clinical goal is to deliver a therapeutically effective dose to tumors while remaining within kidney safety limits, which will be discussed with the FDA.
