BioMarin signs binding term sheet with Ascendis, ending patent disputes for royalties
BioMarin entered a binding term sheet with Ascendis Pharma on August 30, 2026, to settle all pending proceedings over its patent rights covering the C-type natriuretic peptide TransCon CNP (navepegritide, Yuviwel). Ascendis will pay BioMarin royalties on Licensed Product sales, and the parties will dismiss all related litigation with prejudice, including the ITC Section 337 investigation. The filing gives no financial value for the settlement or the royalties beyond the rates, so the effect on BioMarin's results cannot be measured from this filing.
Key points
- Royalty of 20% of annual net sales in the United States and 18% in the European Union, Brazil and South Korea, running until May 2030
- BioMarin grants Ascendis a non-exclusive, worldwide, royalty-bearing license to its patents for all current and potential indications, including achondroplasia and hypochondroplasia
- Term sheet is binding as of August 30, 2026; parties must sign the full Agreement by September 24, 2026, or the term sheet terms continue to bind
