Royalty Pharma Acquires Royalty Rights of Tysabri® for up to $2.85 Billion

The Life Sciences team advised RPI Finance Trust, an affiliate of Royalty Pharma, in its definitive agreement with Perrigo Company plc to acquire royalty rights on worldwide sales of Tysabri® (natalizumab) for $2.2 billion plus potential milestone payments of $250 million in 2018 and $400 million in 2020 to be paid if Tysabri sales exceed certain levels. Tysabri is an FDA-approved treatment for multiple sclerosis. Perrigo acquired the rights to the Tysabri royalty stream through the company’s 2013 acquisition of Elan Corporation plc.

Under the terms of the agreement, Royalty Pharma will acquire all of Perrigo’s rights to receive Tysabri royalty payments from and after January 1, 2017, which Perrigo has under an agreement with Biogen, Inc. Royalty Pharma will pay a cash purchase price of $2.2 billion at closing, plus additional payments of $250 million if the royalties earned on global net sales of Tysabri meet specified thresholds during 2018, and $400 million if the royalties earned on global net sales of Tysabri meet specified thresholds in 2020. Perrigo will also assign to Royalty Pharma certain information and audit rights, and the parties have agreed to allocate certain other obligations under Perrigo’s existing agreement with Biogen. The transaction is expected to close within 30 business days, subject to certain specified closing deliverables.

The team was led by partners Art McGivern, Kingsley Taft, Mitzi Chang and associate Bethany Withers.
