What You Should Know:
– Pfizer announced it will acquire biotechnology company Seagen for $229 per Seagen share in cash, for a total enterprise value of approximately $43 billion. The proposed combination enhances Pfizer’s position as a leading company in Oncology.
Seagen’s medicines, late-stage development programs and pioneering expertise in Antibody-Drug Conjugates (ADCs) strongly complement Pfizer’s Oncology portfolio.
Seagen Background
Seagen is a pioneer in ADC technology, with four of the twelve total FDA-approved and marketed ADCs using its technology industry-wide. ADCs are a transformative modality that is emerging as a powerful tool across a broad range of cancers designed to preferentially kill cancer cells and limit off-target toxicities. Seagen has developed a leadership position in ADC technologies since its founding 25 years ago, with groundbreaking and proprietary technology that is positioned for significant growth in 2023 and beyond. Seagen’s portfolio includes four approved medicines2 that are first- or best-in-class in their respective indications across solid tumors and hematologic malignancies, including three ADCs: ADCETRIS® (brentuximab vedotin), PADCEV® (enfortumab vedotin), and TIVDAK® (tisotumab vedotin). The company also commercializes TUKYSA® (tucatinib). Clinical development programs are ongoing for each of these medicines for potential new tumor types or expanded indications in earlier lines of therapy, with catalysts expected annually through 2027.
Seagen is also poised to expand the impact of its therapeutic approach with its broad and deep pipeline that includes eleven new molecular entities, many with the potential to treat large patient populations and all with global commercial rights.3 The proposed acquisition is also expected to enable for combination potential across both the Seagen and Pfizer pipelines and will leverage Pfizer’s protein engineering and medicinal chemistry capabilities to advance Seagen’s ADC technology to unlock potential novel target combinations and next-generation biologics.
Acquisition Impact
Seagen expects to generate approximately $2.2 billion of revenue in 20231, representing 12% year-over-year growth, from its four in-line medicines, royalties and collaboration and license agreements. When combining the expected strong growth trajectories for these medicines with candidates that could emerge from Seagen’s pipeline, subject to clinical trial and regulatory success, Pfizer believes Seagen could contribute more than $10 billion in risk-adjusted revenues in 2030, with potential significant growth beyond 2030.
