Sandoz acquires rights to Perjeta biosimilar

12 November 2025

Swiss generics and biosimilars leader Sandoz (SIX: SDZ) today announced the signing of a global license agreement to commercialize a proposed biosimilar of oncology medicine pertuzumab.

The agreement with Taiwan-based (6589: TW) is milestone-based for a total consideration of up to $152 million, including an upfront payment and further potential incentives dependent upon market performance. The reference medicine market is worth an estimated $4.1 billion in global sales, and pertuzumab will join the deep Sandoz pipeline with the strategic objective to capitalize on a projected ~$300 billion biosimilar market opportunity over the next 10 years.

Roche posted Perjeta sales of 2.32 billion francs ($2.88 billion) for the first nine month of 2025, down 13% year-on-year.
