Is ibrutinib toxic?
Among the patients treated front-line with ibrutinib, the three most common toxicities leading to discontinuation were arthralgia (41.6%), atrial fibrillation (25%), and rash (16.7%).
Can Ibrutinib cause liver damage?
Increased liver damage from ibrutinib will occur if not detected early, since it is metabolized in the liver by the P450 cytochrome enzyme CYP3A [16], and, therefore, drug levels will rise once liver damage has commenced.
How long do Ibrutinib side effects last?
The irritating side effects that sometime occur with ibrutinib including fatigue, heart burn, diarrhea, and arthritic symptoms typically are noted more at the beginning of therapy. Interestingly, for most patients, these tend to resolve quickly with time and are often non-existent within 2-3 month.

How is ibrutinib toxicity treated?
The ibrutinib clinical trials recommended holding ibrutinib for grade 3+ toxicities until resolution to grade 1, followed by resuming at full dose at least once. The goal was to maintain full BTK occupancy (considered >95%), which is predicted in only 26% to 51% of patients treated at 140 to 280 mg daily.

Can ibrutinib cure CLL?
