Questions and Answers About PIQRAY
Click below to find answers to some of the most common questions about PIQRAY.
PIQRAY is a prescription medicine used in combination with the medicine fulvestrant to treat women who have gone through menopause, and men, who have hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer with an abnormal PIK3CA gene whose disease has progressed on or after endocrine (hormone) therapy.
Your health care provider will test your cancer for an abnormal PIK3CA gene to make sure that PIQRAY is right for you.
It is not known if PIQRAY is safe and effective in children.
PIQRAY is a biomarker-driven treatment approach that specifically targets proteins created by an abnormal (or mutated) PIK3CA gene, which are linked to cancer growth. PIQRAY affects cancer cells, but can also affect healthy cells. Although PIQRAY has been studied in patients with HR+, HER2- mBC, how PIQRAY works has only been demonstrated in laboratory studies.
PIK3CA mutations can only be detected through a specific genomic test ordered by your doctor. Even if you’ve had genetic testing done before, ask your doctor about getting tested specifically for a PIK3CA mutation.
Combination therapy is a treatment strategy of taking multiple medicines. By combining PIQRAY and fulvestrant, you’ll have 2 medicines working differently, but together, to help treat your HR+, HER2- metastatic breast cancer (mBC) with a PIK3CA mutation.
The most common side effects of PIQRAY when used with fulvestrant include hyperglycemia, diarrhea, rash, nausea, tiredness and weakness, decreased appetite, mouth sores, vomiting, weight loss, hair loss, and changes in certain blood tests. PIQRAY can also cause more serious side effects. Learn more about potential side effects here.

Although not all the side effects of PIQRAY can be managed, your health care team may offer suggestions to help manage some of them. It’s important to talk with your doctor or nurse about side effects you experience and the best ways to manage them. Get tips about managing some side effects .
Your doctor will monitor your blood sugar levels before starting and while taking PIQRAY. Your doctor may also have you monitor your blood sugar levels at home, which you should do in the morning, before eating or drinking. Though hyperglycemia is different from diabetes, your doctor may monitor your blood sugar levels more often if you have a history of Type 2 diabetes.
Visit our side effect management page for guidance on a recommended monitoring schedule and more information.
Hyperglycemia is high blood sugar due to any cause, and also a characteristic of diabetes. Type 1 Diabetes is a condition where your body stops making the insulin it needs to allow blood sugar to enter the cells of the body. Type 2 Diabetes is a condition where your body either doesn't make enough insulin or is unable to use it correctly.
If you have a history of diabetes, talk to your doctor about how that could affect your experience with PIQRAY.
Before a rash appears: Your doctor may prescribe an antihistamine to help reduce the chances of a rash developing. Taking antihistamines before a rash appears may decrease the chances of rash and severity of rash, based on the clinical trial.
If a rash does occur: Your doctor may prescribe one or more types of medication to help with symptoms, depending on their severity. Additionally, tips such as wearing loose clothing and using mild and unscented detergent can help you take care of a rash at home.
