New Pill for Hormone-Positive Advanced Breast Cancer

Etcamah (camizestrant) — oral ER antagonist with CDK4/6 for ESR1m HR+/HER2− advanced breast cancer

Health Canada/FDA Approved · United States, Canada, Japan, European Union · September 11, 2026

Condition: Breast Cancer

Who this is for

This is for adults with HR-positive, HER2-negative locally advanced or metastatic breast cancer who are already on an aromatase inhibitor plus a CDK4/6 inhibitor and whose blood ctDNA test shows an ESR1 mutation before imaging progression — and who may be candidates for labelled Etcamah switched onto the same CDK4/6 backbone. It explains the US accelerated label, the Canadian Product Monograph route, the EU EC marketing authorisation (20 July 2026), and the Japanese エトカマ錠75mg approval (19 June 2026), the SERENA-6 progression-free survival numbers, QTc / bradycardia / visual-disturbance watchpoints, how the once-daily 75 mg tablet works with continued CDK4/6 therapy, and how to talk with a breast oncology clinician — without treating an Orbis partner review or a DIY import as the care plan. Authorized is not funded.
