FDA Approves AstraZeneca’s Etcamah for Mutation-Driven Breast Cancer
The U.S. Food and Drug Administration approved a new AstraZeneca cancer medicine called Etcamah.
It is made for some people whose breast cancer has spread and contains a specific mutation.
Doctors must use an approved test to look for that mutation first.
Etcamah works by stopping estrogen from helping cancer cells grow.
AstraZeneca says the medicine delayed cancer progression by more than six months in eligible patients.
An FDA advisory group had earlier said the evidence did not show enough benefit.
The FDA later decided Etcamah could give patients another treatment choice.
AstraZeneca hopes the drug will become a major source of future sales.
The U.S. Food and Drug Administration approved AstraZeneca’s camizestrant, marketed as Etcamah, through its accelerated approval process.
Etcamah can be used with other cancer treatments for metastatic breast cancer patients with a specific mutation linked to disease progression.
Patients must receive an FDA-approved diagnostic test confirming the mutation before taking the therapy.
A prior FDA Oncology Drugs Advisory Committee vote opposed the treatment, citing insufficient evidence of meaningful patient benefit.
AstraZeneca forecasts more than $5 billion in annual Etcamah sales, while analysts project about $2.3 billion by 2032.
