2 DOSAGE AND ADMINISTRATION

2.1 Important Dosage Information

  • AFINITOR and AFINITOR DISPERZ are two different dosage forms. Select the recommended dosage form based on the indication [see Indications and Usage (1)]. Do not combine AFINITOR and AFINITOR DISPERZ to achieve the total dose.
  • Modify the dosage for patients with hepatic impairment or for patients taking drugs that inhibit or induce P-glycoprotein (P-gp) and CYP3A4 [see Dosage and Administration (2.10, 2.11, 2.12)].

2.2 Recommended Dosage for Hormone Receptor-Positive, HER2-Negative Breast Cancer

The recommended dosage of AFINITOR is 10 mg orally once daily until disease progression or unacceptable toxicity.

2.3 Recommended Dosage for Neuroendocrine Tumors (NET)

The recommended dosage of AFINITOR is 10 mg orally once daily until disease progression or unacceptable toxicity.

2.4 Recommended Dosage for Renal Cell Carcinoma (RCC)

The recommended dosage of AFINITOR is 10 mg orally once daily until disease progression or unacceptable toxicity.

2.5 Recommended Dosage for Tuberous Sclerosis Complex (TSC)-Associated Renal Angiomyolipoma

The recommended dosage of AFINITOR is 10 mg orally once daily until disease progression or unacceptable toxicity.

2.6 Recommended Dosage for Tuberous Sclerosis Complex (TSC)-Associated Subependymal Giant Cell Astrocytoma (SEGA)

The recommended starting dosage of AFINITOR/AFINITOR DISPERZ is 4.5 mg/m2 orally once daily until disease progression or unacceptable toxicity [see Dosage and Administration (2.8)].

2.7 Recommended Dosage for Tuberous Sclerosis Complex (TSC)-Associated Partial-Onset Seizures

The recommended starting dosage of AFINITOR DISPERZ is 5 mg/m2 orally once daily until disease progression or unacceptable toxicity [see Dosage and Administration (2.8)].

2.8 Therapeutic Drug Monitoring (TDM) and Dose Titration for Tuberous Sclerosis Complex (TSC)-Associated Subependymal Giant Cell Astrocytoma (SEGA) and TSC-Associated Partial-Onset Seizures

  • Monitor everolimus whole blood trough concentrations at time points recommended in Table 1.
  • Titrate the dose to attain trough concentrations of 5 ng/mL to 15 ng/mL.
  • Adjust the dose using the following equation:

New dose* = current dose x (target concentration divided by current concentration)

* The maximum dose increment at any titration must not exceed 5 mg. Multiple dose titrations may be required to attain the target trough concentration.

  • When possible, use the same assay and laboratory for TDM throughout treatment.
