Zymeworks Secures $250M Funding from Royalty Pharma

Zymeworks (ZYME) and Royalty Pharma (RPRX) announced an agreement for $250M in funding from Royalty Pharma in the form of a non-recourse royalty-backed note with repayments due from 30% of worldwide tiered royalties on Ziihera owed to Zymeworks from Jazz Pharmaceuticals (JAZZ) and BeOne Medicines (ONC). Under the terms of the agreement, Zymeworks will receive $250 million from Royalty Pharma through the issuance of a non-recourse royalty-backed note. Repayment of the note will be secured by 30% of future royalties from the global sales of Ziihera, generated under collaboration agreements with partners Jazz and BeOne, equating to an approximately low to mid-single digit upward tiering royalty up to a pre-specified repayment limit. Royalty Pharma will cease receiving any such royalties when it receives cumulative payments of either 1.65x the note amount by December 31, 2033, or 1.925x the note amount at any time thereafter, at which time no further repayments will be owed with respect to the note. Under the collaboration agreement with Jazz, Zymeworks is eligible to receive tiered royalties of 10% to high teens on global (outside of Asia (other than Japan), Australia and New Zealand) annual sales of Ziihera up to $2.0 billion and 20% on annual net sales above $2.0 billion. Under the collaboration agreement with BeOne, Zymeworks is eligible to receive tiered royalties of mid-single to mid-double digits on annual net sales of Ziihera up to $1.0 billion and 19.5% on annual net sales above $1.0 billion. BeOne holds marketing rights to Ziihera in Asia (excluding Japan), Australia and New Zealand. Zymeworks will retain 70% of royalties on Ziihera sales during the note repayment period, with full royalty rights reverting to Zymeworks once the royalty payments to Royalty Pharma have ceased. All earned regulatory and commercial milestone payments under its agreements with Jazz and BeOne will be retained by Zymeworks, including up to $440.0 million in near-term milestone payments tied to future regulatory approvals of Ziihera in mGEA, $89.0 million regulatory milestones for third indications beyond biliary tract cancer and mGEA, and up to $977.5 million in potential commercial milestone payments, for total potential remaining payments of up to $1.5 billion.
