Acquisition of Fusion completed

AstraZeneca today announced the successful completion of the acquisition of Fusion Pharmaceuticals Inc., a clinical-stage biopharmaceutical company developing next-generation radioconjugates (RCs). The acquisition marks a major step forward in AstraZeneca delivering on its ambition to transform cancer treatment and outcomes for patients by replacing traditional regimens like chemotherapy and radiotherapy with more targeted treatments.

This acquisition complements AstraZeneca's leading oncology portfolio with the addition of the Fusion pipeline of RCs, including their most advanced programme, FPI-2265, a potential new treatment for patients with metastatic castration-resistant prostate cancer (mCRPC), and brings new expertise and pioneering R&D, manufacturing and supply chain capabilities in actinium-based RCs to AstraZeneca. It also strengthens AstraZeneca's presence in and commitment to Canada.

As a result of the acquisition, Fusion has become a wholly owned subsidiary of AstraZeneca, with operations in Canada and the US.

Financial considerations

Under the terms of the definitive agreement, AstraZeneca, through a subsidiary, has acquired all of Fusion's outstanding shares pursuant to a plan of arrangement for a price of $21.00 per share in cash at closing plus a non-transferable contingent value right of $3.00 per share in cash payable upon the achievement of a specified regulatory milestone prior to 31^st August, 2029. Combined, the upfront payment and maximum potential contingent value payment, if achieved, represent a transaction value of approximately $2.4bn. As part of the transaction, AstraZeneca acquired the cash, cash equivalents and short-term investments on Fusion's balance sheet, which totalled $211m as of 31^st March 2024. Fusion shares will be delisted from the Nasdaq Stock Market and deregistered under the U.S. Securities Exchange Act of 1934 and Fusion has applied to cease to be a reporting issuer under applicable Canadian securities laws.

Notes

Radioconjugates in oncology

Radioconjugates (RCs) combine the precise targeting of antibodies, small molecules or peptides with potent medical radioisotopes to deliver radiation directly to cancer cells. By seeking out cancer cells, RCs provide a more precise mechanism of cancer cell killing compared with traditional radiation therapy, with the goal of improving efficacy while minimising toxicity on healthy cells. RCs are administered via systemic delivery, which enables their use in tumour types not accessible to external beam radiation and the targeting of cancer cells that have spread from the main tumour to other sites in the body.

About FPI-2265

FPI-2265 is an actinium-225 based PSMA-targeting RC for mCRPC, currently in a Phase II trial.

Actinium-225 emits alpha particles and holds the promise of being a next-generation radioisotope in cancer treatment. By delivering a greater radiation dose over a shorter distance, alpha particles such as actinium-225 have the potential for more potent cancer cell killing, and targeted delivery, thereby minimising damage to surrounding healthy tissue.
