ASTRAZENECA COMPLETES TRANSACTION FOR MAJORITY EQUITY STAKE INVESTMENT IN ACERTA PHARMA

AstraZeneca today announced that it has completed the transaction to acquire a majority equity stake in Acerta Pharma, a privately-owned biopharmaceutical company based in the Netherlands and US. The transaction, announced in December 2015, provides AstraZeneca with a potential best-in-class irreversible oral Bruton's tyrosine kinase (BTK) inhibitor, acalabrutinib (ACP-196), currently in Phase II/III development for B-cell blood cancers and in Phase I/II clinical trials in multiple solid tumours.

Upon completion of the agreement, AstraZeneca acquired 55% of the entire issued share capital of Acerta for an upfront payment of $2.5 billion and a further unconditional payment of $1.5 billion, to be paid either on receipt of the first regulatory approval for acalabrutinib for any indication in the US, or the end of 2018, depending on which is first.

An extensive development programme is underway for acalabrutinib with the opportunity for initial regulatory submissions in the second half of 2016 for the treatment of patients with specific types of haematological malignancies. Expanding further into B-cell cancers, acalabrutinib is estimated to reach potential peak-year sales in excess of $5 billion globally.

The investment also establishes in-house expertise for AstraZeneca in blood cancers, through the substantial expertise offered by Acerta's approximately 150 employees.

NOTES TO EDITORS

About Acalabrutinib

Acalabrutinib is a highly selective, irreversible, second generation BTK inhibitor, with approximately 1,000 patients treated to date in clinical studies across the entire development programme. More than 600 patients have been treated with acalabrutinib monotherapy. Phase I/II data showing a favourable safety profile and strong efficacy in relapsed/refractory chronic lymphocytic leukaemia patients was presented at the American Society of Hematology Annual Meeting & Exposition in December 2015, with simultaneous publication in the New England Journal of Medicine.

Potentially registrational studies in haematological malignancies are expected to be submitted for regulatory filings in second half 2016. In addition, a head-to-head study versus ibrutinib in high risk chronic lymphocytic leukaemia patients is currently ongoing.

Acalabrutinib is also currently being tested in multiple Phase I/II studies in solid tumours, as monotherapy or in combination with immune checkpoint inhibitors or other standard of care regimens.
