Immunome Exclusively Licenses Zentalis ROR1 Antibody-Drug Conjugate and Proprietary Technology Platform

- Exclusive worldwide license agreement for preclinical ROR1 ADC, on track to submit IND in 1Q 2025 -

- Proprietary ADC platform enhances Immunome's development of next-generation ADC programs -

- Zentalis to receive up-front payment of $35 million in cash and Immunome common stock and is eligible to receive up to $275 million of milestone payments and mid-to-high single-digit royalties -

Dr. Siegall continued: "The next generation of transformative ADCs will be built through combining rigorously selected targets with innovative linker-payload platforms. We believe that the linker-payload technology that underlies ZPC-21 may compare favorably to the platforms of successful ADC franchises-a testament to Zentalis' deep understanding of medicinal chemistry and cancer biology. Immunome will now evaluate and advance Zentalis' platform technology in the context of our multiple discovery-stage ADC programs against undisclosed targets."

Under the terms of the deal, Zentalis will receive an up-front payment of $35 million in cash and Immunome common stock. Zentalis will be eligible to receive up to $275 million of milestone payments for ZPC-21 and the platform technology in addition to mid-to-high single-digit royalties.

"Immunome's leadership team's track record of advancing paradigm-changing ADCs, along with Zentalis' commitment to apply cutting-edge medicinal chemistry to anti-cancer agents, makes Immunome the ideal partner to advance our ADC platform," said Cam Gallagher, President of Zentalis. "This transaction realizes immediate value for our shareholders while enabling the Zentalis team to focus on advancing azenosertib, our oral WEE1 inhibitor with first-in-class and best-in-class potential, through multiple ongoing clinical studies in tumor types with high unmet need."
