GSK is boosting its oncology presence with the £4 billion acquisition of Waltham, Massachusetts-based Tesaro.

The company said the deal will significant strengthen its pharmaceutical business and accelerate the build of its pipeline and commercial capability in oncology.

Tesaro is a commercial-stage biopharmaceutical company, with a major marketed product, Zejula (niraparib), an oral poly ADP ribose polymerase (PARP) inhibitor currently approved for use in ovarian cancer.

Zejula is currently approved in the US and Europe as a treatment for adult patients with recurrent ovarian cancer who are in response to platinum-based chemotherapy, regardless of BRCA mutation or biomarker status.

Clinical trials to assess the use of Zejula in “all-comers” patient populations, as a monotherapy and in combinations, for the significantly larger opportunity of first line maintenance treatment of ovarian cancer are also underway.

These ongoing trials are evaluating the potential benefit of Zejula in patients who carry gBRCA mutations as well as the larger population of patients without gBRCA mutations whose tumours are HRD-positive and HRD-negative.

In addition to, Tesaro has several oncology assets in its pipeline including antibodies directed against PD-1, TIM-3 and LAG-3 targets.

“The acquisition of TESARO will strengthen our pharmaceuticals business by accelerating the build of our oncology pipeline and commercial footprint, along with providing access to new scientific capabilities,” said Emma Walmsley, GSK CEO.

“This combination will support our aim to deliver long-term sustainable growth and is consistent with our capital allocation priorities. We look forward to working with TESARO’s talented team to bring valuable new medicines to patients.”

Lonnie Moulder, CEO of Tesaro, added: This transaction marks the beginning of a new global partnership that will accelerate our oncology business and allow our mission of delivering transformative products to individuals living with cancer to endure.”
