DOSAGE AND ADMINISTRATION
Recommended Dose for Hepatocellular Carcinoma, Renal Cell Carcinoma, and Differentiated Thyroid Carcinoma
The recommended daily dose of NEXAVAR is 400 mg (2 x 200 mg tablets) taken twice daily without food (at least 1 hour before or 2 hours after a meal). Treatment should continue until the patient is no longer clinically benefiting from therapy or until unacceptable toxicity occurs.
Dose Modifications for Suspected Adverse Drug Reactions
Temporary interruption of NEXAVAR is recommended in patients undergoing major surgical procedures [see Warnings and Precautions].
Temporary interruption or permanent discontinuation of NEXAVAR may be required for the following:
-
•Cardiac ischemia or infarction [see Warnings and Precautions]:
-
•Hemorrhage requiring medical intervention [see Warnings and Precautions]
-
•Severe or persistent hypertension despite adequate anti-hypertensive therapy [see Warnings and Precautions]
-
•Gastrointestinal perforation [see Warnings and Precautions]
-
•QTc prolongation [see Warnings and Precautions]
-
•Severe drug-induced liver injury [see Warnings and Precautions]
Dose modifications for Hepatocellular Carcinoma and Renal Cell Carcinoma
When dose reduction is necessary, the NEXAVAR dose may be reduced to 400 mg once daily. If additional dose reduction is required, NEXAVAR may be reduced to a single 400 mg dose every other day [see Warnings and Precautions].
Suggested dose modifications for dermatologic toxicities are outlined in Table 1.

When dose reduction is necessary for dermatologic toxicities, reduce the NEXAVAR dose as indicated in Table 3 below.

|
Continue treatment with NEXAVAR
|
Grade 2: Painful erythema and swelling of the hands or feet and/or discomfort affecting the patient’s normal activities
|
1st occurrence
|
Decrease NEXAVAR dose to 600 mg daily
If no improvement within 7 days, see below
|
|
No improvement within 7 days at reduced dose
or
2nd occurrence
|
Interrupt NEXAVAR until resolved or improved to grade 1
If NEXAVAR is resumed, decrease dose (see Table 2)
|
|
3rd occurrence
|
Interrupt NEXAVAR until resolved or improved to grade 1
If NEXAVAR is resumed, decrease dose (see Table 2)
|
|
4th occurrence
|
Discontinue NEXAVAR permanently
|
Grade 3:
Moist desquamation, ulceration, blistering, or severe pain of the hands or feet, resulting in inability to work or perform activities of daily living
|
1st occurrence
|
Interrupt NEXAVAR until resolved or improved to grade 1
If NEXAVAR is resumed, decrease dose by one dose level (see Table 2)
|
|
2nd occurrence
|
Interrupt NEXAVAR until resolved or improved to grade 1
When NEXAVAR is resumed, decrease dose by 2 dose levels (see Table 2)
|
|
3rd occurrence
|
Discontinue NEXAVAR permanently
|
Following improvement of Grade 2 or 3 dermatologic toxicity to Grade 0–1 after at least 28 days of treatment on a reduced dose of NEXAVAR, the dose of NEXAVAR may be increased one dose level from the reduced dose. Approximately 50% of patients requiring a dose reduction for dermatologic toxicity are expected to meet these criteria for resumption of the higher dose and roughly 50% of patients resuming the previous dose are expected to tolerate the higher dose (that is, maintain the higher dose level without recurrent Grade 2 or higher dermatologic toxicity)
