Dosing for CLL/SLL
Oral, infusion-free* dosing
IMBRUVICA® is available in two formulations, including capsules and a single tablet, once-daily option.
Combination regimens require infusion.
- Administer IMBRUVICA® at approximately the same time each day with a glass of water
- Swallow tablets or capsule whole. Do not open, break, or chew the capsules. Do not cut, crush, or chew the tablets
- 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
Once-daily dosing is necessary to ensure inhibition of BTK enzymatic activity1
Inhibition of BTK by IMBRUVICA® has a disruptive effect on 3 key B-cell processes as shown by in vitro and in vivo studies1:
- Inhibits survival and proliferation1-6
- Inhibits adhesion1,6-11
- Modulates chemotaxis and trafficking1,5,7,9,11-14
Correlation to clinical effect has not been established.
Discontinuation and dose reduction rates in the CLL/SLL registration studies1
The data below are pooled from 5 randomized controlled clinical trials (RESONATE™, RESONATE™-2, HELIOS, iLLUMINATE™, and E1912) and 1 single-arm, open-label clinical trial (Study 1102) in patients with CLL/SLL (N=2,016 total and n=1,133 patients exposed to IMBRUVICA®)
- 4% to 10% of patients discontinued due to ARs
- ARs leading to discontinuation included pneumonia, hemorrhage, atrial fibrillation, neutropenia, arthralgia, rash, and thrombocytopenia
- Approximately 9% of patients had a dose reduction due to ARs
