XOMA Royalty has the potential to net up to $25 million in milestone payments and earn a low to mid-single digit royalty
EMERYVILLE, Calif., Dec. 02, 2024 (GLOBE NEWSWIRE) -- XOMA Royalty Corporation (NASDAQ: XOMA) announced today it now owns an economic interest in seralutinib, a Phase 3 asset being studied in pulmonary arterial hypertension (PAH), through its acquisition of Pulmokine Inc., a privately held company. In 2017, Pulmokine licensed seralutinib to Gossamer Bio, Inc., and in 2024, Gossamer Bio signed a global collaboration and license agreement with Chiesi Farmaceutici S.p.A.
“We acquired Pulmokine to add seralutinib, a Phase 3 asset with strong mechanistic rationale in PAH, to our growing royalty and milestone portfolio while creating a favorable outcome for Pulmokine’s founders and stockholders. In addition, we believe seralutinib has the potential to address several cardio-respiratory conditions beyond PAH in the future,” stated Brad Sitko, Chief Investment Officer of XOMA Royalty. “This transaction marks the second whole-company acquisition we have completed in 2024. We continue to offer creative royalty capital solutions to access assets with the potential to deliver attractive returns to XOMA Royalty’s diverse portfolio.”
Terms XOMA Royalty acquired all outstanding shares of Pulmokine for a $20 million cash payment at closing. In addition, XOMA Royalty will pay success-based consideration contingent on future development and commercial events to Pulmokine stockholders. XOMA Royalty’s net royalties will range from the low to mid-single digits on commercial sales; additionally, the Company will retain up to $25 million of the milestone payments.
Advisors XOMA Royalty was represented by Gibson, Dunn & Crutcher LLP.
