ETCAMAH is for adults with HR+/HER2- metastatic breast cancer in combination with a CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) upon detection of an ESR1 mutation during first-line hormone therapy. ETCAMAH is approved based on a study that measured time to cancer growth or spread (progression-free survival). ETCAMAH is still being studied to confirm these results.
Stay on your first CDK4/6 inhibitor for mBC longer by replacing your current hormone therapy with ETCAMAH
Ask your doctor about taking a proactive approach and getting ahead of metastatic breast cancer (mBC) growth with ETCAMAH
Next-generation oral therapy
ETCAMAH is a next-generation, FDA-approved oral hormone therapy for HR-positive, HER2-negative metastatic breast cancer. It’s approved to take with your current CDK4/6 inhibitor such as palbociclib (Ibrance®), ribociclib (Kisqali®), or abemaciclib (Verzenio®) treatment.
ETCAMAH is approved based on a study that measured time to cancer growth or spread (progression-free survival). ETCAMAH is still being studied to confirm these results.
Upon testing positive for an ESR1 mutation, a clinical trial has shown that replacing your current hormone therapy with ETCAMAH can slow the growth of cancer and extend your time on first CDK4/6 inhibitor.
How Etcamah works in the body
ETCAMAH may work in two ways to help overcome changes in your cancer and slow growth.

IMPORTANT SAFETY INFORMATION ABOUT ETCAMAH® (camizestrant)
What is the most important information I should know about ETCAMAH?
ETCAMAH can cause serious side effects including:
- Changes in electrical activity of your heart (QTc interval prolongation). Taking ETCAMAH in combination with ribociclib or other QTc interval prolonging drugs may cause life-threatening heart rhythm problems and may lead to death. Before starting and during treatment with ETCAMAH, your healthcare provider will do an electrocardiogram (ECG) to check the electrical activity of your heart and do blood tests to check the blood levels of your body salts (electrolytes). Your healthcare provider will treat abnormal electrolyte levels
- Slow heart rate (bradycardia). Your healthcare provider will check your heart rate frequently during the first 30 days of treatment with ETCAMAH if you have bradycardia (heart rate less than 60 beats per minute) before starting treatment and if you take medicines that lower heart rate
Get medical help right away if you get the following signs or symptoms of QTc prolongation and bradycardia including: dizziness, lightheadedness, fainting, feeling that your heart is pounding or racing (palpitations), shortness of breath, or chest pain.
Your healthcare provider may delay treatment or completely stop treatment with ETCAMAH if you have severe side effects.
Before you take ETCAMAH, tell your healthcare provider if you:
- have any liver-related problems
- have a slow heartbeat (bradycardia)
- have heart problems including irregular heartbeats and QTc prolongation
- are pregnant or plan to become pregnant. ETCAMAH can harm your unborn baby
- Females who are able to become pregnant
- Your healthcare provider will check that you are not pregnant before you start treatment with ETCAMAH
- Use effective non-hormonal birth control (contraception) during treatment with ETCAMAH and for 1 month after the last dose. Talk to your healthcare provider about birth control methods that may be right for you during this time
- Tell your healthcare provider if you become pregnant or think you may be pregnant
- Males with female partners who can become pregnant
- Use effective birth control during treatment with ETCAMAH and for 1 week after your last dose
- are breastfeeding or plan to breastfeed. It is not known if ETCAMAH passes into your breast milk. Do not breastfeed during treatment with ETCAMAH and for 1 week after the last dose. Talk to your healthcare provider about the best way to feed your baby during treatment with ETCAMAH
Tell your healthcare provider about all the medicines you take, including prescription and over‑the‑counter medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take any heart and blood pressure medicines.
