Piqray vs. Kisqali
Are Piqray and Kisqali the Same Thing?
Piqray (alpelisib) and Kisqali (ribociclib) are kinase inhibitors used to treat metastatic breast cancer.
Piqray is used in combination with fulvestrant for the treatment of postmenopausal women, and men, with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated, advanced or metastatic breast cancer as detected by an FDA-approved test following progression on or after an endocrine-based regimen.
Kisqali is used in combination with an aromatase inhibitor as initial endocrine-based therapy for the treatment of postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer.
Side effects of Piqray and Kisqali that are similar include diarrhea, rash, nausea, fatigue, decreased appetite, inflammation of the mouth and lips, vomiting, hair loss, abdominal pain, swelling of extremities, fever, urinary tract infection (UTI), headache, and itching.
Side effects of Piqray that are different from Kisqali include weight loss, indigestion, dry nose, changes in taste, dry skin, prolonged aPTT, and laboratory abnormalities (increased or decreased blood sugar, increased creatinine, decreased lymphocyte count, increased GGT, increased ALT, decreased hemoglobin, increased lipase, and decreased calcium).
Side effects of Kisqali that are different from Piqray include low white blood cell count (neutropenia, leukopenia), constipation, back pain, anemia, low levels of lymphocytes in the blood (lymphopenia), insomnia, and shortness of breath.
Piqray may interact with CYP3A4 inducers, BCRP inhibitors, warfarin, and acid reducing agents.
Kisqali may interact with ritonavir, boceprevir, clarithromycin, conivaptan, grapefruit juice, pomegranates or pomegranate juice, indinavir, azole antifungals, lopinavir/ritonavir, nefazodone, nelfinavir, saquinavir, phenytoin, rifampin, carbamazepine, St John's wort, alfentanil, cyclosporine, dihydroergotamine, ergotamine, everolimus, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, amiodarone, disopyramide, procainamide, quinidine, and sotalol.
