Is Palbociclib a chemotherapy drug?

Palbociclib (Palbociclib) is not a traditional form of chemotherapy (chemo). Palbociclib is a"targeted drug therapy" known as a CDK 4/6 inhibitor. Targeted therapies are only effective in certain cancers with specific genetic characteristics. For example, some cancer cells contain proteins, such as CDK, HER2, or mTOR, that can promote rapid or abnormal growth. Doctors can testpatients to see if they have cancer that responds to targeted drug treatments.

Chemotherapy is the use of oral or injected drugs to kill cancer cells. Chemotherapy also affects healthy cells, but the body can usually repair the damage to healthy cells once treatment stops. Targeted drugs like palbociclib can be used with certain hormone therapies to combat advanced hormone receptor-positive (HR+) breast cancer in HER2-negative patients. Palbociclib blocks specific proteins in cells called CDK4 and CDK6. Blocking these proteins helps slow cell division that leads to the growth of new cancer cells. Because these drugs target specific areas, they may be associated with fewer, less severe, or different side effects than traditional chemotherapy.
