SEED Concurrently Enters into Share Purchase Agreements for its Series A-3 Financing Led by Eisai

• The SEED-Eisai Research Collaboration leverages Eisai’s leading expertise in neurodegeneration and cancer. SEED is entitled to receive upfront and milestone payments of up to $1.5 billion plus tiered royalties upon Eisai’s exercise of their exclusive rights under the strategic research collaboration

• Concurrently, SEED has launched Series A-3 financing with a first close of $24 million from investors led by Eisai. A second close is targeted for Q4 2024

• The Series A-3 financing will advance clinical development of SEED’s internal lead program in cancer, expand its TPD platform and pipeline, and supplement prior investments in SEED from Eli Lilly and BeyondSpring
  

KING OF PRUSSIA, Pa., Aug. 06, 2024 (GLOBE NEWSWIRE) -- SEED Therapeutics Inc. (“SEED”), a biotechnology company focused on harnessing and engineering Molecular Glues for targeted protein degradation (TPD) of disease-causing proteins, today announced a strategic research collaboration with Eisai Co., Ltd. (“Eisai”) to discover, develop, and commercialize novel molecular glue degraders for multiple undisclosed neurodegeneration and oncology targets. The collaboration is coupled with a Series A-3 financing led by Eisai.

Key Aspects of the SEED – Eisai Collaboration:

• Collaboration Roles: SEED will lead preclinical discovery activities for the selected targets, including E3 ligase selection and identification of the appropriate molecular glue degraders. Eisai will have exclusive rights to develop and commercialize compounds derived from this collaboration.

• Financial Terms: SEED is entitled to receive upfront payment and preclinical, clinical, regulatory and sales milestone payments of up to $1.5 billion, plus tiered royalties upon Eisai’s exercise of their exclusive rights under the strategic research collaboration.
  

The SEED–Eisai collaboration follows a separate and on-going research collaboration between SEED and Eli Lilly to discover and develop Molecular Glue Degraders for undisclosed targets. (Click here for related press release.)

Series A-3 Financing:

SEED also announces a Series A-3 financing with a first close of $24 million from investors led by Eisai. A second close is targeted for Q4 2024.

The Series A-3 financing is expected to further accelerate SEED’s clinical development of internal proprietary programs in cancer and in neurodegeneration, expand its TPD platform and pipeline, and supplement prior investments from Eli Lilly and BeyondSpring.

• SEED will advance its internal, potentially “best-in-class” oral RBM39 Degrader into Phase 1 safety/efficacy testing beginning in 2025 for rationally selected, biomarker-driven cancer indications. SEED’s program will build on Eisai’s pioneering discovery of a class of RBM39 degraders over three decades.

• SEED will also progress its internal Tau degrader program (for Alzheimer’s disease) into in vivo efficacy in 2025, and IND in 2026.

• SEED will scale its proprietary TPD platform development. With global neurodegeneration drug development leaders Eisai and Eli Lilly as investors and research collaborators, SEED will extend its research and thought leadership in the discovery and development of oral Molecular Glues for the treatment of neurodegenerative diseases.
  

Dr. Takashi Owa, Eisai’s Chief Scientific Officer, stated: “SEED has a cutting-edge technology platform to discover a class of molecular-glue target protein degraders, one of the most highlighted modalities in the modern drug discovery. While the anti-myeloma drug lenalidomide from the molecular-glue class has been successful in the oncology field, our research collaboration will also focus on utilizing this modality in the neurology field. Our collaboration with SEED is unique and clearly differentiated, and I look forward to learning of the important progress being made by both companies to achieve Social Good.”

Dr. Lan Huang, SEED’s Co-Founder, Chairman, and CEO, added, “We are honored to collaborate with Eisai, a world-leading drug development powerhouse, to discover impactful medicines for undruggable targets. Looking ahead, SEED’s unique Molecular Glue discovery platform on neurodegenerative disease will be further strengthened through our collaborations with both Eli Lilly and Eisai (under separate collaboration agreements), two global pioneers in the timely development of treatments for neurodegeneration, including approved therapies for Alzheimer’s disease. Finally, having demonstrated the scalability and versatility of our TPD platform through the success of multiple pipeline programs across various key therapeutic indications, our Series A-3 financing and non-dilutive funding of R&D milestone payments from both Eli Lilly and Eisai, SEED is well-positioned to advance our internal high-profile programs into clinics, and to create great value for patients and our shareholders.”
