EsoBiotec SA, a biotechnology company specializing in in vivo cell therapies, has announced a definitive agreement to be acquired by AstraZeneca ( AZN ) PLC .

The agreement represents a major step forward for EsoBiotec, which has demonstrated encouraging early clinical results with its Engineered NanoBody Lentiviral (ENaBL) platform.

AstraZeneca ( AZN ) is acquiring all of EsoBiotec’s outstanding equity for a total of up to $1 billion. The deal includes an initial $425 million payment at closing, with up to an additional $575 million in contingent consideration based on development and regulatory milestones.

EsoBiotec’s ENaBL platform utilizes highly targeted lentiviruses to deliver genetic instructions directly to immune cells like T cells. The technology programs these cells to recognize and destroy cancerous cells or autoreactive cells related to immune-mediated diseases.

In contrast to conventional treatments that require extracting cells from patients, modifying them externally, and enduring prolonged manufacturing periods, ENaBL works by enhancing the immune system within the patient’s body itself, by administering therapies through a simple intravenous (IV) injection.

AstraZeneca ( AZN ) held $5.6 billion in cash and equivalents as of December 31.

Price Action: AZN shares traded lower by 0.66% at $77.08 in premarket at last check Monday.
