Alpelisib interactions

Food & lifestyle

• high-fat foods

  Moderate

  Absorption

  Food significantly enhances the oral absorption and bioavailability of alpelisib. When administered with a high-fat high-calorie meal (985 calories with 58.1 g of fat) or a low-fat low-calorie meal (334 calories with 8.7 g of fat) the AUC and Cmax of a single dose of alpelisib was increased by 73% and 84% and 77% and 145%, respectively. There were no clinically significant differences in alpelisib AUC between the two types of meals. In addition, food appears to have a more pronounced effect on the solubility of alpelisib than gastric pH.

  What to do: To ensure maximal oral absorption, alpelisib should be administered with a meal.

• Kidney Diseases

  Moderate

  No dose adjustment is recommended for patients with mild to moderate renal impairment (CrCl 30 to < 90 mL/min). Close monitoring is recommended when using alpelisib in patients with severe renal impairment (CrCl < 30 mL/min) as its effect on the pharmacokinetics is unknown.

• Skin Diseases

  Moderate

  Severe cutaneous reactions, including Stevens-Johnson Syndrome (SJS) and Erythema Multiforme (EM) were reported in patients treated with alpelisib.
