Baxter International Inc. has announced that it has signed a definitive agreement to acquire the Oncaspar® (pegaspargase) product portfolio from Sigma-Tau Finanziaria S.p.A. The acquisition further accelerates the innovation capabilities and the commercial presence of Baxter BioScience in growing oncology markets for rare and orphan diseases.

The company gains the leading marketed biologic treatment Oncaspar, the investigational biologic calaspargase pegol, and an established oncology infrastructure with clinical and sales resources.

The Oncaspar transaction is expected to close in the third quarter. By mid-year, Baxter expects to establish the BioScience business as a separate, publicly traded, innovation-oriented biopharmaceutical company, Baxalta Incorporated.

Oncaspar is a first-line biologic used as part of a multi-agent chemotherapy regimen to treat acute lymphoblastic leukemia (ALL). It is currently marketed in the United States, Germany, Poland and certain other countries and has approximately USD $100 million in annual sales. ALL is a rapidly progressing cancer of the white blood cells responsible for more than 80 percent of childhood leukemia cases.

"The Baxter BioScience legacy of delivering solutions for orphan diseases and small patient populations and our global presence positions us well to accelerate the growth of the Oncaspar portfolio globally," said Ludwig Hantson, Ph.D., president of Baxter BioScience. "With Oncaspar, Baxalta will bring an established standard of care therapy to more patients worldwide through the pursuit of additional indications and regulatory approvals across the globe."

"Oncaspar is a strong strategic fit for our rapidly expanding oncology business, as it complements our R&D programs in hematologic cancers," added David Meek, head of oncology for Baxter BioScience. "The acquisition provides an immediate commercial footprint in the United States and Europe with a heritage of expertise in treating this challenging disease."

In addition to the currently marketed formulation of Oncaspar, Baxter BioScience intends to continue the development of a lyophilized formulation, which is being investigated to enhance product stability to support product supply continuity.

As part of the acquisition, Baxter BioScience is also acquiring a related new chemical entity calaspargase pegol, a biologic in development for the treatment of ALL with an increased shelf life that is expected to reduce dosing frequency. Further, the company plans to investigate Oncaspar for potential new indications, including in additional ALL patient populations with significant unmet needs, as well as for acute myeloid leukemia (AML).

"We are confident that this transaction provides benefits for patients, our business and our employees. The Oncaspar team will gain beneficial resources by joining forces with Baxter BioScience to bring this valuable treatment to more patients around the world," said Andrea Montevecchi, CEO of Sigma Tau Finanziaria SpA.

The acquisition is expected to accelerate the company's efforts to capitalize on the rapidly growing oncology market, with an estimated $10 billion total market potential across current oncology indications for Baxter's pipeline assets. It also complements recent momentum on several partnerships within the oncology pipeline, including positive Phase III results for the investigational treatment pacritinib for myelofibrosis as well as the recent regulatory filings of MM-398 for metastatic pancreatic cancer.

Under the terms of the agreement, Baxter will purchase the portfolio for USD $900 million before working capital and other transaction adjustments. The company expects to finance the transaction through a combination of foreign cash and debt. This transaction is expected to be accretive to adjusted earnings on a cash basis in the first full year and increasingly accretive thereafter. The closing of the transaction, expected in the third quarter, is subject to regulatory approvals and other customary closing conditions.

Baxalta Incorporated will host an investor conference on Tuesday, May 19, during which the company's leadership will address the growing oncology business, strategy and emerging pipeline.
