This quarter was no exception and was accompanied by further progress in the pipeline”, commented David Loew, Chief Executive Officer. “We have also continued to launch across several indications and lines of therapy, including the recent rollouts of Iqirvo and Onivyde, which are progressing well. Supported by the performance so far this year, we are further increasing our 2024 sales and margin guidance.” “We have built a track record of delivery, grounded in a strong foundation of external innovation, commercial excellence and our ongoing mission to offer more choices for patients.” Full-year 2024 guidance Based on the strong performance in the third quarter, Ipsen has further increased its financial guidance for 2024: Total-sales growth greater than 8.0%, at constant currency (prior guidance of greater than 7.0%). Based on the average level of exchange rates in September 2024, an adverse impact on total sales of around 1.5% from currencies is expectedCore operating margin greater than 31.0% of total sales (prior guidance of greater than 30.0%) Pipeline update In September 2024, the European Commission conditionally approved Iqirvo 80mg tablets for the treatment of PBC in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA, or as a monotherapy in patients unable to tolerate UDCA. Iqirvo was approved in the same setting by the U.S. FDA in June 2024. In September 2024, the European Commission also approved Kayfanda as a treatment for pruritus in children from as young as six months of age who have Alagille syndrome (ALGS). Odevixibat, under the brand name Bylvay, is already marketed in the E.U. for the treatment of progressive familial intrahepatic cholestasis (PFIC), and in the U.S. and E.U. for PFIC, and in the U.S. for ALGS. In the same month, final results from the CABINET Phase III trial were presented at the 2024 European Society for Medical Oncology Congress and were published in the New England Journal of Medicine, reinforcing the efficacy benefits of Cabometyx in advanced neuroendocrine tumors. It was announced at that time that Ipsen had submitted an extension of indication Marketing Authorization to the European Medicines Agency. Business development In August 2024, Ipsen entered into an agreement to sell its rare pediatric disease Priority Review Voucher. As part of the agreement, Ipsen received a cash payment of $158m in the third quarter. In October 2024, Eton Pharmaceuticals entered into an agreement with Ipsen to acquire Increlex® (mecasermin injection). The transaction is expected to close before the end of 2024. Arbitration proceedings with Galderma As of 30 September 2024, two arbitration proceedings initiated by Galderma against Ipsen at the International Chamber of Commerce (ICC) were ongoing. The first dispute, initiated by Galderma in 2021, pertains to the territorial scope of the commercial partnership related to Azzalure® (abobotulinumtoxinA) and Dysport under an agreement signed in 2007 in the E.U., in certain Eastern European countries, and in Central Asia. The Tribunal of the ICC Internal Court of Arbitration issued a final award, in October 2024, dismissing most, if not all, of Galderma's claims in this first arbitration and ordered that Galderma bear the majority of the legal fees and arbitration costs incurred by Ipsen. A second dispute was initiated by Galderma in November 2023, related to the validity of Ipsen’s 2023 termination of a joint R&D collaboration agreement entered into in 2014 under the parties’ respective early-stage neurotoxin programs, including the development of IPN10200. At this stage, Ipsen cannot reasonably predict any potential financial impact from this final remaining arbitration process, for which it intends to fully defend and vindicate its rights.

Attachment Ipsen - YTD 2024 sales announcement

Cancer specialist Ipsen is signing on to help grow the reach of tovorafenib outside the U.S. Just three months after scoring an accelerated FDA approval for Ojemda, Day One Biopharmaceuticals is teaming up with another fellow oncology specialist to grow the medicine's global reach. Thursday, Day One and Ipsen unveiled an ex-U.S. licensing agreement for tovorafenib (approved as Ojemda in the U.S.) in pediatric low-grade glioma (pLGG) and "any future indications developed by Day One." In exchange for regulatory and commercial rights to tovorafenib outside the U.S., Ipsen is forking over $111 million upfront, including a $40 million equity investment in Day One. Based on potential success down the road, Day One could be in line for up to $350 million in milestones plus "tiered double-digit royalties." In a release, Ipsen said its "deep heritage and expertise in oncology" will allow the company to "accelerate the delivery of this innovation as teams focus on regulatory activities outside the U.S." As the company noted, patients with pLGG suffer from symptoms including vision and speech problems, neurological symptoms, fatigue, nausea and more. The disease can "significantly" impact a child's development and quality of life. The deal comes three months after Ojemda secured accelerated FDA approval as a treatment for pLGG in patients 6 months and older whose tumors have a BRAF fusion or rearrangement, or a BRAF V600 mutation. In their Thursday release, Ipsen and Day One described pLGG as the "most common childhood brain tumor." In the disease, Day One's drug is going up against Novartis' combination of Tafinlar and Mekinist, which in 2023 scored its own FDA nod to treat pLGG cases with BRAF V600 mutations, a more restricted use. Ojemda is California-based Day One's first commercial product and carries a peak sales estimate of $750 million from analysts at JPMorgan. As for Ipsen, the company separately on Thursday presented its first-half financial results. The drugmaker's first-half sales grew 8% year over year, reaching 1,659 billion euros ($1.8 billion). During the first half, Ipsen said its Exelixis-partnered cancer med Cabometyx and Dysport for spasticity and cervical dystonia drove its sales growth, along with Bylvay for patients with Alagille syndrome and Onvyide for certain cancers. While the company's profit margin declined slightly during the first six months of the year, Ipsen attributed the decrease to higher R&D spending. With the first half in the books, Ipsen said it expects a full-year sales increase of 7% compared with its prior guidance of 6%.
