Generic PI3K Inhibitor for Breast Cancer

This inhibitor, Alpelisib, is made to help treat breast cancer in people who have the PIK3CA mutation and their cancer doesn’t have the HER2 protein on its surface, and it’s positive for hormone receptors. Alpelisib really zeroes in on the PI3K signaling pathway. It comes in three doses—50, 200, and 300 milligrams—all in these film-coated tablet things.

The dose doctors usually go for is 300 milligrams of the stuff, once a day, and it’s best taken with a meal. Each pack of them has 28 tablets, making it a good four-week supply.
