Mantle Cell Lymphoma
The recommended dose of IMBRUVICA for MCL is 560 mg (four 140 mg capsules) orally once daily.
Dose Modifications for Adverse Reactions
Interrupt IMBRUVICA therapy for any Grade 3 or greater non-hematological, Grade 3 or greater neutropenia with infection or fever, or Grade 4 hematological toxicities. Once the symptoms of the toxicity have resolved to Grade 1 or baseline (recovery), IMBRUVICA therapy may be reinitiated at the starting dose. If the toxicity reoccurs, reduce dose by one capsule (140 mg per day). A second reduction of dose by 140 mg may be considered as needed. If these toxicities persist or recur following two dose reductions, discontinue IMBRUVICA.
Recommended dose modifications are described below:
|Toxicity Occurrence||MCL Dose Modification After Recovery
Starting Dose = 560 mg
|CLL Dose Modification After Recovery Starting Dose = 420 mg|
|First||Restart at 560 mg daily||Restart at 420 mg daily|
|Second||Restart at 420 mg daily||Restart at 280 mg daily|
|Third||Restart at 280 mg daily||Restart at 140 mg daily|
|Fourth||Discontinue IMBRUVICA||Discontinue IMBRUVICA|
Dose Modifications for Use with CYP3A Inhibitors
Avoid co-administration with strong or moderate CYP3A inhibitors and consider alternative agents with less CYP3A inhibition.
Concomitant use of strong CYP3A inhibitors which would be taken chronically (e.g., ritonavir, indinavir, nelfinavir, saquinavir, boceprevir, telaprevir, nefazodone) is not recommended. For short-term use (treatment for 7 days or less) of strong CYP3A inhibitors (e.g., antifungals and antibiotics) consider interrupting IMBRUVICA therapy until the CYP3A inhibitor is no longer needed [see Drug Interactions (7.1)].
Reduce IMBRUVICA dose to 140 mg if a moderate CYP3A inhibitor must be used (e.g., fluconazole, darunavir, erythromycin, diltiazem, atazanavir, aprepitant, amprenavir, fosamprevir, crizotinib, imatinib, verapamil, grapefruit products and ciprofloxacin) [see Drug Interactions (7.1)].
Patients taking concomitant strong or moderate CYP3A inhibitors should be monitored more closely for signs of IMBRUVICA toxicity.
