2.1 Recommended Dosage

Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma and Waldenström’s Macroglobulinemia

The recommended dosage of IMBRUVICA for CLL/SLL and WM is 420 mg orally once daily until disease progression or unacceptable toxicity.

For CLL/SLL, IMBRUVICA can be administered as a single agent, in combination with rituximab or obinutuzumab, or in combination with bendamustine and rituximab (BR).

For WM, IMBRUVICA can be administered as a single agent or in combination with rituximab.

When administering IMBRUVICA in combination with rituximab or obinutuzumab, consider administering IMBRUVICA prior to rituximab or obinutuzumab when given on the same day.

​Chronic Graft versus Host Disease

​The recommended dosage of IMBRUVICA for patients age 12 years and older with cGVHD is 420 mg orally once daily, and for patients 1 to less than 12 years of age with cGVHD is 240 mg/m2 orally once daily (up to a dose of 420 mg), until cGVHD progression, recurrence of an underlying malignancy, or unacceptable toxicity. When a patient no longer requires therapy for the treatment of cGVHD, IMBRUVICA should be discontinued considering the medical assessment of the individual patient.

Administration

Administer IMBRUVICA at approximately the same time each day.

Swallow tablets or capsules whole with a glass of water. Do not open, break, or chew the capsules. Do not cut, crush, or chew the tablets.

Follow Instructions for Use for further administration details of IMBRUVICA oral suspension.

If a dose of IMBRUVICA is not taken at the scheduled time, it can be taken as soon as possible on the same day with a return to the normal schedule the following day. Do not take extra doses of IMBRUVICA to make up for the missed dose.

2.2 Dosage Modifications for Adverse Reactions

​For adverse reactions listed in Table 2, interrupt IMBRUVICA therapy. Once the adverse reaction has improved to Grade 1 or baseline (recovery), follow the recommended dosage modifications (see Table 2).

2.4 Dosage Modifications for Use in Hepatic Impairment

Adult Patients with B-cell Malignancies

The recommended dosage is 140 mg daily for patients with mild hepatic impairment (Child-Pugh class A).

​Patients with cGVHD

​The recommended dosage is 140 mg daily for patients 12 years of age and older with total bilirubin level >1.5 to 3 x upper limit of normal (ULN) (unless of non-hepatic origin or due to Gilbert’s syndrome).

​The recommended dosage is 80 mg/m2 daily for patients 1 to less than 12 years of age with total bilirubin level >1.5 to 3 x ULN (unless of non-hepatic origin or due to Gilbert’s syndrome).
