Biotech Giant Expands Cell Therapy Capabilities with ENaBL Platform
In a major move to strengthen its cell and gene therapy portfolio, AstraZeneca has announced the acquisition of biotechnology firm EsoBiotec for up to $1 billion. The deal includes a $425 million upfront payment and an additional $575 million tied to regulatory and development milestones.
The acquisition will give AstraZeneca access to EsoBiotec’s Engineered NanoBody Lentiviral (ENaBL) platform, a groundbreaking technology that enables rapid genetic modification of immune cells inside the body, drastically reducing the time required for cell therapy treatments.
Revolutionizing Cell Therapy with ENaBL Technology
The ENaBL platform represents a significant breakthrough in cell therapy, offering a faster and more efficient alternative to traditional methods.
- Traditional cell therapy treatments require weeks of processing, involving the extraction, modification, and reinfusion of immune cells.
- EsoBiotec’s ENaBL technology eliminates this extended process by genetically modifying immune cells directly inside the body, cutting treatment times down to minutes.
- This platform has the potential to enhance patient access to life-saving therapies while reducing treatment costs and logistical challenges associated with conventional cell therapies.
“This acquisition aligns with AstraZeneca’s long-term strategy to expand our capabilities in cell and gene therapy and bring next-generation treatments to patients faster,” the company stated.
Deal Structure and Financial Terms
AstraZeneca will acquire 100% of EsoBiotec’s outstanding equity on a cash and debt-free basis.
- $425 million upfront payment will be made upon deal closing.
- Up to $575 million will be paid in contingent milestones based on development progress and regulatory approvals.
- The deal is expected to close in Q2 2025, subject to regulatory approvals.
- AstraZeneca confirmed that the acquisition will not impact its financial guidance for 2025.
