AstraZeneca, a global biopharmaceutical leader, has announced a definitive agreement to acquire EsoBiotec, a Belgium-based biotechnology company specializing in in vivo cell therapies. The transaction, valued at up to $1 billion, aims to advance EsoBiotec’s innovative Engineered NanoBody Lentiviral (ENaBL) platform, which has shown encouraging early-stage results in oncology and immune-mediated diseases.
Enhancing Cell Therapy with ENaBL
EsoBiotec’s ENaBL platform represents a breakthrough in cell therapy by leveraging targeted lentiviral vectors to genetically program immune cells directly within the body. This in vivo approach eliminates the need for traditional ex vivo cell modification, which typically involves extracting, engineering, and reinfusing patient cells—a process that can take weeks and requires complex manufacturing infrastructure.

By delivering genetic instructions via intravenous (IV) administration, ENaBL enables immune cells, including T cells, to recognize and attack cancer cells or autoreactive cells involved in immune disorders. This innovation has the potential to significantly reduce treatment costs, streamline manufacturing, and improve accessibility for patients worldwide.

Strategic Impact & Financial Terms
Under the terms of the acquisition, AstraZeneca will acquire all outstanding equity of EsoBiotec for a total consideration of up to $1 billion. This includes an upfront payment of $425 million at closing and additional milestone-based payments of up to $575 million, contingent upon the achievement of specific development and regulatory goals.
The transaction, expected to close in Q2 2025, is subject to customary regulatory approvals. AstraZeneca has confirmed that the acquisition will not impact its financial guidance for 2025.

Expanding AstraZeneca’s Cell Therapy Pipeline
With this acquisition, EsoBiotec will become a wholly owned subsidiary of AstraZeneca while maintaining its operational base in Belgium. The move is poised to strengthen AstraZeneca’s position in oncology and immune-mediated diseases by integrating a disruptive, scalable cell therapy approach into its pipeline.
Susan Galbraith, Executive Vice President of Oncology and Haematology R&D at AstraZeneca, highlighted the significance of the acquisition: “We are excited about the opportunity to accelerate the development of EsoBiotec’s ENaBL platform. This innovative in vivo technology aligns with our vision of transforming cell therapy and making it more accessible to patients worldwide.”
Jean-Pierre Latere, CEO of EsoBiotec, also emphasized the potential of this collaboration: “Partnering with AstraZeneca provides us with the resources and expertise needed to scale our technology and bring novel cell therapies to a broader patient population. We look forward to driving forward this shared mission.”
Future Outlook
As cell therapy continues to evolve, in vivo approaches like ENaBL are expected to redefine the treatment landscape for cancer and immune disorders. AstraZeneca’s investment in EsoBiotec reinforces its commitment to pioneering next-generation therapies and expanding patient access to cutting-edge medical innovations.
For the Indian healthcare industry, this acquisition signals a shift towards more efficient, scalable, and cost-effective cell therapies—offering new opportunities for research collaborations, biotech partnerships, and advanced therapeutic solutions in oncology and beyond.
