On June 17, 2024, PTC Therapeutics, Inc. (“PTC”) exercised an option to sell half of its retained royalties on Roche’s Evrysdi to a subsidiary of Royalty Pharma plc (“Royalty Pharma” or the “Company”) for approximately $242 million upfront. This option arose from the Evrysdi royalty transaction with PTC announced in October 2023.
Evrysdi, marketed by Roche, is an orally administered survival motor neuron-2 (SMN2) splicing modifier for the treatment of spinal muscular atrophy (SMA) that was approved by the U.S. Food and Drug Administration in 2020. In 2023, Evrysdi generated sales of approximately CHF 1.4 billion ($1.6 billion), an increase of 39% at constant exchange rates versus the prior year.
Transaction Terms
The total royalty that Roche pays on worldwide net product sales of Evrysdi is tiered ranging from 8% to 16%. Following the transaction announced today, in total, Royalty Pharma is increasing its ownership of the Evrysdi royalty from 81% to 90.5% (before the cap, as detailed below), equating to a royalty of 7.2% to 14.5% (not including any exercise of future options by PTC). Royalty Pharma will receive the increased 90.5% of the Evrysdi royalty starting with royalties paid in respect of sales for the second quarter of 2024.
Additionally, until December 31, 2025, PTC will have the option to sell its remaining 9.5% of the Evrysdi royalty to Royalty Pharma for $250 million less royalties received.
