AstraZeneca said a late-stage trial confirmed the benefit of breast cancer drug Enhertu in patients with an innovative form of the disease who formerly treated with another therapy.
In a 600-patient trial called DESTINY-Breast02, Enhertu -developed with Japan’s Daiichi Sankyo- likened in contradiction of a treatment pre-determined by physicians in people with HER2-positive metastatic breast cancer.
The trial assessed a comparable breast cancer patient population as the DESTINY-Breast01 mid-stage trial, which was the basis for early approvals in Europe and numerous other countries, AstraZeneca said.
In the DESTINY-Breast02 study, Enhertu met the chief goal of statistically significant and clinically meaningful upgrading in progression-free survival, a measure of how long a person can live without their disease getting worse. The drug also improved inclusive survival, a key secondary goal.
Detailed results will have obtainable at a forthcoming scientific conference.
The HER2 protein contributes to the growth and spread of breast cancer. About one in five patients with breast cancer measured HER2-positive, rendering to AstraZeneca.
AstraZeneca’s shares were up about 2% on Monday morning, although Daiichi’s shares jumped about 15%.
Drug Enhertu:
Formerly this month, AstraZeneca and Daiichi secured U.S. approval precisely targeting patients with so-called HER2-low breast cancer, paving the way for billions in sales.
Enhertu’s first support came in late 2019, as a third-line treatment for breast cancer patients with HER2-positive disease, in the United States.
It has since also secured numerous approvals in other breast cancer settings, as well as forms of lung and gastric cancer.

The drug, which produced sales of $214 million in 2021, goes to a class of therapies called antibody drug conjugates. It includes a monoclonal antibody chemically linked to a cell-killing chemotherapy drug.
AstraZeneca protected partial rights to the Daiichi Sankyo compound three years ago in a deal worth up to $6.9 billion.
