Important Facts About Verzenio® (ver-ZEN-ee-oh). It is also known as abemaciclib.
Verzenio is a prescription medicine used to treat certain types of breast cancer known as HR+/HER2– (hormone receptor positive/human epidermal growth factor receptor 2 negative) breast cancer.
It is a medicine you can take if:
- You have node-positive early breast cancer that has a high risk of coming back as determined by your healthcare provider. Verzenio is given along with hormonal therapy to women and men.
- Or, the cancer has spread to other parts of the body (metastasized). If you are postmenopausal, or male, then Verzenio is given with an aromatase inhibitor as initial endocrine-based therapy. If you are a female or male, and the cancer has gotten worse after hormone therapy, then Verzenio is given with fulvestrant. If you are female or male and the cancer has gotten worse after both hormone therapy and chemotherapy, then Verzenio is given by itself.
It is not known if Verzenio is safe and effective in children.
