BioMarin signs settlement and license deal with Ascendis, with royalties on TransCon CNP sales
BioMarin entered into a Settlement and License Agreement with Ascendis Pharma on September 24, 2026, replacing an August 2026 binding term sheet. Ascendis receives a non-exclusive license to BioMarin patents covering TransCon CNP (navepegritide, Yuviwel), and BioMarin receives royalties on net sales until May 2030. The filing says the parties will dismiss all pending litigation between them over the patents, and it does not disclose dollar amounts.
Key points
- Agreement dated September 24, 2026, deemed effective August 28, 2026, and supersedes the term sheet reported on August 31, 2026
- Royalty of 20% of annual net sales in the United States and 18% in the EU, Brazil and South Korea, until May 2030
- Pending litigation between the parties relating to the BioMarin patent rights to be dismissed with prejudice
- Ascendis agreed not to challenge BioMarin's patent rights; no dollar figures disclosed
